Questions related to Thinking
Can I change my reality with my thoughts and what is stopping you from turning your invention idea into a reality?
So, I want to extract bone marrow from mice for an experiment, but I don't need all tens of millions of cells that I would get. So I was thinking that I could freeze down the left over cells for future use. I would want to eventually culture the cells into eosinophils with SCF/Flt-3 and IL-5 media. But I've never frozen down freshly extracted bone marrow (or anything, actually) and neither has anyone in my lab. What would be the best procedure for this?
Im asking this to get understanding of what the experts think is research topics that is easy for me to do when i get to honours .A topic that needs research to be done .Im writing a concept and will attach it to my Hons Biokinetics and Hons Sports Sci application .I want to write this concept on a topic that a Bio and HP student can work on so if i get into either honours programme i can just get going with my research .Instead of writing two concept notes i just want to write one since it will be my first time writing it .Im going to write it up in my june holidays before semester 2 starts so i can apply to honours with it .Any advice would be appreciated
When preparing an article, you cannot change geographical names, species names and especially similar words in methodology. Can you share your thoughts on this issue?
Is sustainable development or social capital essential for Africa's socioeconomic transformation? Despite widespread preaching of sustainable development by institutions like the United Nations and NGOs, tangible progress has been lacking, akin to an overdue pregnancy—quantitative rather than qualitative. Is Africa still in need of this gospel or what it requires now not just sustainable development but robust social capital to achieve lasting socioeconomic transformation. My thinking. What is yours.

Just as in the human animal, and even more often than in the human animal, petting among the other mammals is primarily, although not exclusively, male activity which is directed toward the female. As in the human species, it is the male which is more likely to be aroused psychologically and usually before he makes any physical contact. (Alfred Kinsey)
Who do you think is the most famous, or rather influential, person in human history?
Hello,
I am a student from Vytautas Magnus University. I am currently writing my bachelor's thesis on decision-making styles and divergent thinking. I read your article about adapting its decision-making to another language. I wanted to ask, maybe you know which order the questions of the questionnaire are supposed to be in and could tell it to me?
Thanks for Your response in advance.

Dear Alessio Ishizaka · Enrique MU
I read your paper
What is so special about the analytic hierarchy and network process?
My comments
First of all, I want to congratulate you for your extensive bibliographical search about AHP and ANP. I am impressed by the number of authors you mention in your paper, and by your comments.
However, it is only a bibliographic search enumerating papers written on AHP and ANP, but there is not a single line that justifies these methods, other than mentioning the large number of papers published, which is undisputable, and by far more than other MCDM methods
Obviously, you are an advocate of the method and wanted to make its virtues known, but you do not even mention its drawbacks, that outperform several times over those good attributes it may have. You mention multiple applications of AHP, the same as other methods that are not ‘special’, and no mention is done on AHP abundant limitations. Therefore, your analysis is biased.
Technically, AHP is a descriptive process, and as that irrational, considering that it is based on intuitions, very useful in many aspects of life, but normally useless when applied to serious MCDM scenarios, and thus, assuming that the DM judgements are applicable to real-life, and to thousands or millions of persons, against common sense and something that nobody can accept.
AHP is based on the wishes and moods of individuals pursuing what they perceive or feel, without reasoning, which is natural in many instances of our life, instead on addressing on what it ought to be as in normative rational methods, which not coincidently constitute the largest number of MCDM methods. In my opinion, AHP may be appropriate to personal decisions like selecting a restaurant or a site for and you say that it is due to easiness of uses and a vacation, but it has no place in complex scenarios. Simply, it cannot manage them.
However, as you mention, it is the most used MCDM method, due to its easiness, which is true, and to its rigorous mathematical base, which is false.
AHP is probably the easiest MCDM method to learn. The DM determines the criteria, alone or with experts, but curiously, without considering the alternatives they must evaluate, and then compares two criteria at a time and assign a value according to his intuition, and that is all.
Even if he does not reason ‘appropriately’, that is, transitively or consistently according to percentage, the software refutes him and -suggests’ a correction. The DM has no alternative but accept, as a robot, it does not matter if he agrees or not.
What the DM does not realize is that a decrease, for instance from 7 to 6, is not minor, due to the ratio or logarithm scale, the method remains silent about that. Please, correct me If I am mistaken.
In addition, one wonders, and AHP does not explain it, why the DM must be coherent or consistent in his/her estimates? As an example, if you must select among three restaurants A, B and C for dinner and comparing quality and price, and you already determined that for you, quality is three times more important than price, and for that reason, close A, that is, you prefer to lose some money to get a gain in quality.
Now you compare A and C and finds that C has also a good quality, but at a considerably lower price, and you decide that you prefer to lose a little quality, to get a gain in price. That is, you reversed your priorities.
Finally, comparing B and C you reach the conclusion that both have good quality and good price, so it is indistinct what you chose
Consequently, A>B=C>A, there is not transitivity here. And what is wrong with this analysis? Nothing, just human decision. This elemental example also shows two AHP errors.
First, it considers that weights are constant. As you can see, they could not be, and
Second, criteria depend on the alternatives, not the other way around. If you do not have alternatives, it means that always, and for everything, i.e., houses, trips, careers, cars, food, furniture, etc. you prefer quality on price.
A>B=C>A, does this mean that you must respect transitivity?
In AHP, it does not matter that the DM must judge on items on what he may not have the faintest idea, like comparing cost with contamination, cost with public health, or cost with manufacture, and thus, assuming that he must be an expert or knowledgeable in each area, or posses the expertise each stakeholder has in the company that owns the project. I think that you will agree that this is something hard to digest.
In my opinion you should explain which were the advances in AHP that you mention. Which advances, using fuzzy, or becoming hybrid with other methods like TOPSIS or DEMATEL, to name only some of them?
When you consider these serious hidden shortcomings. it is natural that people select AHP; it makes practitioners believe that complex problems can be solved by intuition. Reasoning, researching, consulting, examining? What for? That is unnecessary as per AHP standards. One of the things that bother the most in AHP it is the lack of rational explanations.
What happens if the scenario demands using Boolean notation, i.e., 1 or 0, or if there is precedence between alternatives, or if criteria are interrelated, or if some alternatives are exclusive and other inclusive, or if a criterion establishes conditions on another? According to AHP the solution is easy: Just disregard all of these irrelevant and annoying characteristics of the problem.Don’t worry, simply, ignore all of them; nobody will notice, because the results cannot be validated, since there is not a yardstick to compare to, and also because many journals’ reviewers will accept that and approve the manuscript, something extremely frequent.
Just read the abstracts of problems ‘solved’ by AHP in Scopus on in the Web. The most common is that they disregard something that Saaty said very clearly and in writing: AHP works only - and with reason - with independent criteria, something difficult to find in most real-life projects. Just for that simple fact most AHP solutions are invalid. By the way, it is very easy to prove that Saaty was right in this.
This is the reason of the ‘success’ of AHP. Nobody will discuss it, as nobody rebutted me when I denounced these things along my eight years in RG, and after 270,380 readings of my questions and answers, and 2,277 contributions as of today, according to metrics from this platform.
Curiously, along these years nobody rebutted none of what I assert. Extract your own conclusions.
AHP was useful back in the 70s, but now it is history, ANP, based on the same principles and arbitrariness of AHP, is however a little better, because it is more realistic although very difficult to understand, and also assuming some inexistent concepts such as impact and feedback, and that were never explained by Saaty.
AHP violates System’s’ Theory by claiming that one of its greatest advantages is the decomposition of a problem. True, for understanding it, but not for solving.
You cannot maximize or minimize a criterion independently of the others, because a problem is a system, and as that, it must be solved considering everything at the same time. It is as studying the performance of a car selecting independently the best engine, the best transmission, the best tires, and the best style. It cannot be done separately, due to the fact that the aerodynamics of the car, its tires, its transmission, electronic and electric system, etc. are input to design the best engine. Sounds reasonable?
However, this is what AHP does, and that ANP improvedby using a network.
I guess that Saaty understood that AHP was faulty on this regard, and then decided to correct it by developing ANP, and in so doing burying AHP, and this took place more that 30 years ago.
AHP is the most used MCDM in the world? Absolutely true, but why?
Because it has managed to convince people that real-life problems can be easily solved by intuition, as for instance complex problems like regional planning, or deciding by intuition that photovoltaics cells are better than wind turbines to generate electricity.
They are only technical issues, why to bother with them?
AHP is a system based on false assumptions such as:
1- You can compare two different criteria, that is legit, but what you cannot do is assign a value to those preferences. How for instance, do you decide that tenderness is say three times more important than love? This comparison is fantasy.
2- AHP assumes (Saaty words), that trade-offs are equivalent to weights. Both are completely different concepts and not interchangeable.
3- AHP assumes that what is the mind of the DM, can be applied to the real-world. This may be true only in his / her imagination, and convinced because AHP quietly equals them.
Explanation? No, what for?
4- On what grounds AHP assumes that criteria weights are constant? This misjudgement can be easily demonstrated, as I have done many times in RG
5- To say nothing that the DM is reduced to the role of a robot, when a formula instructs him/her to correct him or herself
6- Where is the rational in using compensation, that means that increasing in 0.5 human health is compensated by a proportional decrease in land use or in paving roads? This is a disparate.
7- Who says they these trade-offs are lineal? Only suppositions and because they were normalized to sum 1.
8- What axiom says that the DM may vote for hundreds or thousands of people? Quite the opposite, the Arrow ‘s theorem just addresses this issue and of course denies it, calling this action a dictatorship.
9- Even the so-called fundamental table is dubious, because it is a poor imitation of the Weber and Fechter law relating incentives increases with log responses. AHP happily assumes that the value in criterion C1 on C5 or ratio importance, equals to incentives increases.
10- Can you imagine using AHP or ANP in simulation where you have to change parameters hundreds of times? It would be a nightmare.
11- How useful can be a method where the criteria must be independent?
I can continue, but this is enough to prove the falsehood of AHP.
I have been many years in RG and since the very first date I commented AHP, mentioning these very aspects. If I were wrong it would have been natural that scientists and practitioners would have rebutted me. Again, I never received a rebuttal. Why?
For obvious reasons: There are not responses to them.
I want now to address some specific points of your paper:
1- In page 2 you say “development of the theoretical foundations of the AHP”
A researcher may have as many theories as he wants; the problem is to demonstrate a mathematical as well as common sense foundation, both absent in AHP, other than the Eigen Value and geometric mean. All other are only assumptions like results from pair-wise comparisons, trade-offs equivalence to weights, need of transitivity, weights that can evaluate alternatives, sensitivity analysis using the ceteris paribus principle, existence of feedback in ANP. etc.
None of them are mathematical, and many rejected by scientists
2- Using fuzzy AHP? What for? To improve arbitrary values?
3- In page 3 you speak about modelling, possibly the most important aspect to be considered in MCDM. It appears that the meaning and importance of modelling is absent in AHP, where it reduces to putting values in a matrix.
Modelling means to represent as close as possible a project or scenario in a mathematical format or matrix. Since I speak based on facts, I will put some examples:
a) How do you model in AHP, that alternative A4 must precede only alternatives A1, A2, A3, A9?. This is applied anywhere as in manufacturing, construction, health cate, etc.
b) How do you model in AHP, that considering alternatives A2 and A7 they are exclusive, i.e., it is one or the other, therefore, one of them must not be in the ranking. This is usual in road projects, for instance determining the best route between two cities.
c) How do you model in AHP that a criterion such as heavy snowfall may alter another criterion as maximum speed in a road, or in other words, the speed criterion depends on the heavy snowfall criterion, only when a certain value is reached. Used in hgh mountain highway is comparison with lower-level routes, of in modal transportation.
d) How do you model in AHP that an alternative must comply with a certain number of criteria? For instance: A6 and A8 must satisfy at least these four criteria C5, C7, C8 and C14. A common question when analyzing urban planning
e) How do you model in AHP, that if alternative A7 is selected, also A1 must be selected?
Found in sewerage networks
f) How do you model in AHP that a certain alternative must forcefully be in the ranking? Typical of projects already initiated or for pollical reasons.? For instance, a promise made by a candidate to major before elections
g) How do you model in AHP that out of 89 environmental indicators, the DM wants as a result only 25 to analyze. Used in selecting indicators
h) . How do you model in AHP, that when you reduce indicators, the resulting indicators in the final result must incorporate as much as possible the information contained in the alternatives not considered in the ranking? Used in urban and regional planning
i) How can you use the same criterion with two different means? For example, in providing water to a housing complex you need to establish a minimum and a maximum limit simultaneously, in such a way for the software to work within these limits?
I have many more questions like these most of them encountered in real-life problems in my life and all of them addressed using MCDM methods. Could you please consider answering how would you model them in AHP or even in ANP?
I will be grateful for your answer
I my humble opinion, it is evident in analyzing these real-world scenarios that AHP was not designed to solve complex problems, but perhaps I am mistaken of did not understand the power of AHP, and for this reason I ask for your answers. Using your own words, which are then the morphological ways used in AHP to solve real problems?
4- In page 7 you cite “I get it, it is like going to the optometrist who asks you whether you see better with one lens or the other; except that there is the additional question of how much better can you see?”
This known example reminds me another from Saaty relative to determine areas of geometrical figures. Both examples are biased because in both cases you know the real result which allows you to make comparisons. As you know, this situation ss inexistent in MCDM
5- In your page 8 you make references to rank reversal in AHP
Yes, it was discovered in AHP, but later it was discovered that it is common practically in all MCDM methods.
In my opinion it is an unavoidable phenomenon related not with the MCDM methods but due to geometrical reasons. It was nothing to do with inconsistencies.
I would love to discuss this subject with you publicly or privately, either in RG, email, or WhatsApp.

I was recently watching a lecture on EM (lesson on E fields from sources with density λ) at a US university. (As a masters holders on general pedsgory&learning, something rare for a physics background, i think I can have an opinion.)
Things that impressed me.
** accuracy, linear logic and causal progression, clarity, simplicity.
** he pointed on magic word i.e keywords, which helps student focus and he thereby centered his lesson i.e it was not unrelated parts
** elements of the lesson reolicated standard physics skills practices such as identifying symmetry, taking limit fsctors for derived expressions, step by step construction of differentials and integration
**he dramstized lesson i.e unexpected simplifications or cool /fancy results
Things that didn't.
** he assumed students are familiar with polar coordinates
** he started with an expressions of coulimb's law& E fields definition without reasoningbits origins (maybe previews class?), so many students were lost
** he used a very plain pedagogical plan: develop a few laws in previews lesson and do applications of them, in volume, thinking students will get dragged into the bottom line physics.
** the importance of the main skill, finding exact expressions for E fields, was soaring in the levels of mandatory with no hint to possibilities knowing it opens, novelty it enables, so to motivate them to endorse the skill
I know teaching physics is not an easy task and maybe each teachers can master a few facets of it but not all. This teacher passed the minimum for me. But overall, his ommisions, if they reflect the general situation, show that students could be learning more if they were absent and that we should sdmit fault and revamp the field.
I will try to dry a 50% ethanol solution to obtain my dry extract. When I tried to have a 3rd party remove the solvent from my 20mL sample using purely the rotavap, they told me there was difficulty in drying it so I was thinking of only removing the ethanol such that I can safely lyophilize it. I was thinking of concentrating the sample to around 10% of its initial volume such that even if there's still some ethanol in it, I can simply dilute the extract with water to avoid any problems in the freeze dryer.
Dear scientists,
Faced now with the rediscovery of already known compounds, which natural source do you think would be best for screening and isolating new bioactive molecules?

Hi everyone,
I am staining leukocytes isolated from mouse kidneys in flow cytometry. I stimulated the cells with PMA/Ionomycin + BFA for 4 hrs in T-cell medium (RPMI + Pen/Strep + 10 % FCS + 50 uM beta-mercaptoethanol) and stained them for surface markers, T-cell transcription factors and IFNg and IL17A.
When I plot the cytokine production (IFNg-BV711 vs IL17A-BV650) in CD4+ T cells, I noticed that beside my single-positive populations, there are events on a somewhat straight diagonal line that seem to be double-positive. There are some other events that are double-positive that are more scattered around, which is why I think the events on the diagonal could be a technical artifact (see attached plot).
I am also attaching my FMOs for IFNg-BV711 and IL17A-BV650 where these events are not present.
I'd highly appreciate your thoughts on this.
Thanks a lot,
Jasper

As part of a capstone project, we are a group of graduate students researching innovations (technological or otherwise) that have the potential to transform the business model in American journalism. Our challenge is to propose ideas that make it more financially sustainable without sacrificing public trust. Much of our focus has been on advertising as the adjacent business and we also have been exploring different applications of AI, blockchain, etc., but are hoping to gain more insights generated by "out-of-the-box" thinking.
What innovations have you encountered that you think could help support a unique business like news? We will credit you for any new paths you might set us on!
Thank you.
What cognitive skills are necessary for creativity and innovation and how does cognitive flexibility support creativity within the critical thinking process?
Hello there,
in the lab we have a Fritsch Pulverisette 7 planetary ball mill. If one wants to dry-grind dried and "smallish-cut" banana peel to a powder, the usage of the device isn't recommended. A colleague tried to grind grape pomace in it and it didn't work ( I believe he used the ~5mm ZrO2 balls).
So, why doesn't this work that well? And even more important: with what kind of balls (which substance, diameter..) do you think this would work best?
Thank you for an answer!
Regards, Vera

In my theory, the speed of gravitational waves could be 76 m/sec greater than the speed of photons. If what I'm saying could be true (i.e. experimentally verifiable), then it would be proof that the photon has a non-zero mass!!
Hi,
if someone has data that are scored:
1 for poor, 2 for adequate and 3 for good.
Can you take a mean average if a score of less than 1 is not possible?
I'm thinking if a mean score of 2.5 were calculated, it'd be assumed this is out of 3, ie including the possibility of a score of <1
Tips welcome please,
Thank you.
Dear all, I found a unique soil having CEC (cation exchange capacity) below 50 cmolc/kg but PBS (percent base saturation) as high as 260%. Actually, the soil has very high amounts of calcium (Ca) and sodium (Na).
Why do you think that the soil contains PBS greater than 100% ?
I have a question regarding your recent manuscript submission experiences, especially with Elsevier. It appears that there has been an increase in desk rejections, a decrease in available reviewers, and longer review times❗❓
While the impatience caused by COVID-19 and the rise of AI-driven research have contributed to the surge in paper submissions, I'm curious to know if there could be any political factors influencing these trends in specific countries 🤔
I would appreciate hearing your thoughts on whether you have observed similar trends and your perspective on the potential influence of politics in this context.
Hello,
I am trying to use the linear finite element method combined with the Newmark method to calculate the dynamic response of a floating frame system. I don't want to use the modal superposition method in this code. So I build an equation of Md2x/dt2+Kx=F directly where F presents the external force. The stiffness matrix is established from the Euler beam.
The origin frame structure is a square that has a side length of 15 m and the cross-section of it is a circle whose diameter is 0.7m. A constant force of 1000N is set on the lower side of the square frame. When I set one of the points as a fixed point, the code seems to run well as shown in Fig.1.
However, when I make the frame a floating one, the beams start to deform unexpectedly as shown in Fig. 2. The length of the beam becomes much larger than 15 m. I think the stiffness is strong enough for such a structure as it hardly deformed in the fixed scenario.
I wonder if there must be a fixed point or if something else should be considered in solving the dynamic response of such a floating frame system.
Thank you for your reply.
Hi All,
I am an academician and doing some research.
In this research, I have collected a few mind maps for a specific scenario. Now i want to analyze them and try to identify any patterns in them. Can anyone suggest any tool/software in which i could upload all the mind maps in graphical format (network) and look for any patterns in thinking processes?
Let me explain more. I gave a specific scenario to some participants and asked them to think about the scenario and draw their thinking process as a mind map (A sample mind map is attached). Now I have five mind maps and want to analyze them in network format (instead of converting them to text) to look for any patterns in thinking processes. How i can do this? Can anyone guide please?
Thanks.

Can we stop global climate change? Does human scientific power reach the world's climate change? What is the response of the researchers?
As you know, humans are very intelligent and can predict the future climate of the world with hydrology, climatology and paleontology. But don't countries, especially industrialized countries, that produce the most harmful gases in the earth's atmosphere and think about the future of the earth's atmosphere? Do they listen to the research of climatologists? What would have to happen to get them to listen to climate scientists?
Miloud Chakit added a reply
Climate change is an important and complex global challenge, and scientific theories about it are based on extensive research and evidence. The future path of the world depends on various factors including human actions, political decisions and international cooperation.
Efforts to mitigate and adapt to climate change continue. While full recovery can be challenging, important steps can be taken to slow progression and lessen its effects. This requires global cooperation, sustainable practices and the development and implementation of clean energy technologies.
Human scientific abilities play an important role, but dealing with climate change also requires social, economic and political changes. The goal is to limit global warming and its associated impacts, and collective action at the local, national, and international levels is essential for a more sustainable future.

We can stop climate change, but we won't! We have scientific knowledge but no political will. One can blame Russia and China for refusing to cooperate, but half of the US population (Republicans) deny that climate change is a problem and prefer their promiscuous lifestyles to the answer:
All climate change is loaded on CO2 responsible for the greenhouse effect. Therefore, scientific experiments from several independent scientific institutions around the world should be conducted to determine what the greenhouse effect is at different concentrations of CO2. Then, a conference of a reputable and professional organization with the participation of all independent scientific bodies should be held to establish standards on CO2 concentrations and propose policy measures accordingly.
The second action that can be taken is to plant as many trees and plants as possible to breathe CO2 and release oxygen. Stop any deforestation and immediately plant trees in any tree-filled areas.
Lucy George added a reply:
We have the knowledge, tools and resources to ensure a livable and sustainable future for all. Carbon dioxide and other heat-trapping gases are major contributors to global warming. Therefore, reducing greenhouse gas emissions is very important and should be done as soon as possible to achieve zero greenhouse gas emissions. Both forests and oceans play an important role in regulating our climate, so increasing their natural ability to absorb carbon dioxide can also help prevent global warming.

I think it is difficult to stop global climate change, but, on the other hand, we can develop adaptation mechanisms with this change
Mrutyunjay Padhiary added a reply:
The challenge of combating global climate change is complicated and multidimensional, involving scientific, technological, political, economic, and social initiatives. Even though we may not be able to "stop" climate change entirely at this time, we can surely lessen its worst consequences and adjust to the changes that are already occurring. It is true that advances in science have allowed us to gain an in-depth knowledge of the mechanisms causing climate change as well as the tools and techniques that can be used to slow it down. Scholars from diverse fields such as ecology, engineering, economics, climatology, and social sciences are actively investigating climate change and devising remedies for it.
How does futures thinking contribute to sustainability?
Ibn Rushd proposed that intellect is just one, that is a sub-set of god. We can think of the forms that this intellect forms, thus we have common notions, laws of physics, general physiology etc. (This is my understanding, but I just have started learning Rushd.) Is that intellect continuously creating new forms?
Or in general where can I find more about this concept? Because I believe it can be stretched to extended mind hypothesis and probabilistic distributions.
A new trend of open an transparent peer reviewing is growing. In one hand, this would encourage reviewers to actively review because this save their intellectual property they add to the articles. In addition review reports will be more serious. On the other hand, being exposed to the Author(s) may lead to some critics. Please add your thoughts.

Introducing Artificial Intelligence in the first year of engineering studies offers students a foundational understanding of its principles and applications. This early exposure fosters relevance, interdisciplinary skills, and prepares them for future technological demands. It cultivates critical thinking and creativity, equipping them with essential tools to tackle complex problems in diverse fields. But, what about their personal skill and learning process?

How can I sterilize the pipette without autoclaving? I am afraid that the autoclave would ruin the mechanics of the pipette.
Thanks
More than 360 million tons of plastic waste is being generated every year, and only 9% of this is being recycled. Who is building solutions around this mammoth issue. What's being researched and what technological solutions are ready to be implemented on mass scale.
Please share your thought and useful links.

Dear colleagues,
I have confirmed that people are beginning to use ChatGPT to do their NIH reviews. I believe this is a dangerous precedent given its well-known errors, biases, and lack of original thought. I’ve written a letter to NIH regarding these concerns and would welcome your input (please use “suggest” mode) and signatures. Please feel free to distribute this note to others who may find it of interest. I’m also happy to discuss whether to send this just to NIH or jointly, as an opinion piece to somewhere open with a reasonably high profile, like JAMA.

I have been using a rheometer to characterize my sample and recently we found out that our gap setting is very wide compared to the recommended gap of x3 the particle size.
the Dz particle size of the DLS result has found to be around 0.005 mm which 3x0.005mm should be our measuring gap but we used 1mm gap ever since the project started without DLS test results that time.
Should we change the settings accordingly and disregard previous rheo results?
Would like to know your thoughts. Thanks!
Should we prohibit the false statements from the papers published in academia journals?
The words that “Einstein's famous equation E=mc2” is a sentence directly copied from internet. It is a general sentence about E=mc2. But, it is clear, this is a false statement. Now, it is well known that it is De Pretto who originally presented E=mc2 from the energy of atomic nuclei. His explanation about E=mc2 is the current explanation in today’s theory of relativity. And, Ohanian showed that in 7 papers, Einstein’s mathematics derivations about this equation are wrong.
And, these sentences are also false statement: 1) Einstein predicted the invariance of the speed of light or Einstein’s postulation of the invariance of the speed of light, 2) Einstein predicted the gravitational light bending or Einstein’s gravitational light bending.
(PDF) Anti-ethics and pseudoscience: On Albert Einstein's theory of relativity (V2) (researchgate.net)
these problems are introduced in detailed.
I was astonished at that, in the books or articles about the theory of relativity, this kinds of statement: Einstein predicted xxx, Einstein’s principle/postulation about xxx, Einstein obtained xxx, and so on, are all false statement. Could you find out one of such kinds of statement is true?
In the past 100 years, we obtained the maximum scientific innovations. These innovations are much more than the sum of that before 100 years. But, it is very unfortunate, the development of theoretical physics is stopped or slowed. Some people think that “Physics is dead”. Here we emphasize, the main reason for the death of physics is that the false statements are prevailing in the papers and books published in the famous academia journals.
We think, we are all the honest people. We don’t like or hate lie and false statement. Therefore, could we reject the false statement in scientific papers with the journals, magazines, books and so on that publish the false statements?
How can we do?

Hi everyone, I hope someone could help me. I have two bacterial strains that I isolated by streaking them in solid media and collecting an individual colony, repeating this process 2-3 times to ensure their purity. Then I extracted their DNA from a liquid culture and run an electrophoresis on Agarose gel 1%. Now, I found four bands, one of which I think may be a plasmid, but two of them are above my hypotetical genomic DNA. Is it possible for this bands to be a superplasmid? I also thought about the possibility of a contaminant, but I doubt it because all my media are superselective (for chimolitoautotrophs acidophiles) and also because I'm sure I cultured an isolated colony for each one.
Waiting for answers or hypothesis. I hope all of you are doing well :)
Akin to the oral "polio vaccine technology", is it possible for a healthy human to build antibodies against a said "bacterium, an example being a Steptococcal infection?".
In my opinion, yes we can. Our bodies have the required armoury "an adept immune system and the relevant enzymes", to tackle bacterial infections.
Please elucidate in detail, how you think our bodies could fight against a bacterial infection.
The previous discussion had been answered so well by "Rizzi". Looking forward to an answer like that of "Rizzi'.
In order to submit a paper some authors choose journals which offer one side blinded revision, so that the identity of the referee/s remains/remain unknown for the author. Nevertheless other authors prefer journals with two side blinded revision.
I personally prefer the last option, more impartial in my opinion. I wonder what is your opinion. What do you think about this? Thank you very much in advance.
Its very interesting topic, when the AI can be implemented in personal counselling.
Dear colleagues

Clinical > book. Therefore, if a barber was trained and had a track record of successfully giving a very specific surgery then, is more likely to succeed than an MD who only has read books without clinical experience.
It's important to remember that while there may be conflicts and divisions among people based on various factors such as race, nationality, religion, or ideology, it is essential to recognize and respect the shared humanity that unites us all. Embracing our common humanity can help bridge divides and promote understanding and empathy.
The shared humanity that unites all of us refers to the fundamental qualities and characteristics that we all possess as human beings. These include:
- Emotions: We all experience a range of emotions, including joy, sadness, anger, fear, and love.
- Capacity for Reason: We all have the ability to reason, think critically, and solve problems.
- Social Connections: We all have a need for social connections and relationships with others.
- Physical Needs: We all have basic physical needs such as food, water, and shelter.
- Vulnerability: We are all vulnerable to illness, injury, and death.
- Diversity: We all come from different backgrounds, cultures, and experiences.
Recognizing and embracing these shared qualities can help us to connect with others, promote empathy and understanding, and work towards a more peaceful and just world.

Hello!
I want to know how to test the electrochemical stability of the electrolyte (2M ZnSO4 solution)
I have measured electrochemical stability window of a electrolyte by 3 electrode system(WE:SS RE: ag/agcl CE:SS) before.
However, the measurement results show that ESW is measured too broadly. so i think it is not proper to measure the potential window of electrolyte.
then How should I configure a three-electrode system to obtain appropriate measurement results?
WE:Pt RE: ag/agcl CE:Pt Is this configuration appropriate? or WE:Zn RE: ag/agcl CE:Pt?
We use synthetic gRNA from IDT but we think have some problems for sgRNA hybridization with Cas9.
any suggestion is welcomed!
Telomere length has been recognized as one of the best biomarkers of aging, indicating its importance in understanding the aging process. However, the evidence suggesting telomere length as a definitive biomarker of aging in humans is not conclusive and remains equivocal.
Staying in harsh environments like space stations can lead to telomere lengthening as an adaptive response to stress and radiation exposure. Research on astronauts and individuals in high background radiation areas has revealed interesting findings regarding telomere dynamics in such conditions. Stressors such as space radiation and microgravity can trigger telomere lengthening, which typically reverses upon returning to Earth. This phenomenon is influenced by factors like radiation dose, dose-rate, and radiation type, underscoring the complexity of telomere modifications in extreme environments.
Similarly, residing in another challenging setting, such as an underwater compound in a Florida lagoon, may also result in telomere lengthening due to increased pressure and exposure to environmental stressors. The compound's atmospheric pressure is 70% higher than at the surface, impacting bodily functions such as urination and metabolism. Researchers like Dr. Joseph Dituri are investigating the prolonged effects of this heightened pressure on the human body, as it could potentially offer insights into reversing the aging process and extending lifespan.
The elevated pressure is thought to boost stem cell proliferation, telomere length, and collagen production, potentially slowing down or reversing aging effects. Nonetheless, it's crucial to recognize that continuous telomere replenishment is a hallmark of immortal cells like cancer cells, necessitating further research to grasp the possible consequences of these transformations.
I welcome your comments.

what are your thoughts ?
Critical thinking and problem solving are considered fundamental skills for the 21st century learner. This requires that the 21st century teacher must first of all be a critical thinker and a problem solver. To what extent do you think graduate teachers are being prepared to be critical pedagogues?
Nowadays, Researchers are more inclined towards hybrid-based models of analysis such socio-pragmatics, stylistic-pragmatics and the like.........What do you think?

I am struggling to get my work on Fermat's last theorem peer reviewed as it appears to be too simplistic/ not relevant to the mathematical journals I have so far contacted. However, being biased I think it's at least worthy of logical consideration and would appreciate any advice to this end.
For reference:
Abstract
This investigation assumed Fermat’s conjecture to be incorrect, i.e. that his equation has a whole number solution to enable consideration of the rationality of the equation’s terms by constructing a 1st triangle with sides representing the whole number, i.e. rational digits, a, b and c, with perpendicular divisors, h1, h2 andh3, and a 2nd, ‘similar triangle’, (with identical angles) but two sides representing divisors h1, and h2. Logical analysis then showed that the perpendicular divisors are also rational digits. Hence the two right angle triangles formed by the divisor, h1, in the 1st triangle can be analysed as Pythagorean Triples since all 3 sides of each triangle being rational can be represented as a fraction p/q of two integers, as long as the denominator q is not equal to zero. Thus, by appropriate multiplication of a combination of all their denominators the sides of the two right angled triangles can be transformed into integers of a larger, scaled triangle, with the same mathematical properties as the original.
This was further interrogated by the use of a Mathcad computer program to determine a Difference Ratio, DR, based on variations between the trigonometric functions calculated as per Fermat’s equation and those as Pythagorean Triples. It was seen, as expected, that both sets of calculations gave identical results unless the integrity of the latter was maintained by limiting certain internal ratios to a given number of decimal points thereby ensuring their sides rationality. The Fermat’s set should automatically give a rational number solution if his conjecture is incorrect as per this supposition and the DR value should at some point equate to zero. However, graphical representation of these calculations shows that DR actually diverges away from zero, for any given set of analysis, with increases in both the Fermat index, n, and the number of decimal points. Hence, it is concluded that this investigation demonstrates, at least to engineering standards, that Fermat’s last theorem is correct, but also that this methodology could be a possible pathway to Fermat’s claimed ‘marvelous’ proof.

If humans are so "complex", is it always harder to understand human behavior [patterns] than to understand similarly functioning patterns in other animals? NO !!
Of course not: we see as other humans see and, to some notable extent, what they see; we hear what they can hear; we smell what they can smell; we understand the types of things they are trying to understand and master; and we understand (roughly) what they are trying to accomplish at each stage of life ('stage' both in the strict sense, of the ontogeny that is child development, and otherwise). WITH RESPECT TO NO OTHER ANIMAL DO WE HAVE THESE COMMONALITIES TO USE AS PART OF OUR UNDERSTANDING.
Then, how is it that all this does not help us; I , for one, am not willing to believe that we are yet otherwise extremely complex to any point of not being able to come to understand humans (ourselves). [( In most cases, claims of complexity can be regarded as simply indications of confusion* (and ignorance) -- and not necessarily anything more. And, the confusions are often not necessary at all, even in the first place.)]
FOOTNOTE: Try the proposed word substitution ("confused/confusion" for "complex/complexity") and see.
Let me explain:
It is as if bad philosophy has put a "spell" (actually: blocks and limitations, over-generalizations and other wrongful mental behavior patterns, aka "thought") on us that incapacitate our moving forward, thinking along/upon more constructive lines such as (in small part) indicated above [(but much more clearly indicated, and then outlined, in other parts of my writings)]. We very much too often ask "what have the philosophers thought?" when, frankly, that hardly matters at all (they may have had some point sometimes at some junctures but, with their same body of philosophy, they commonly very much over-"define" (notably wrongly and falsely), and then overgeneralize their 'position' to make unsubstantiated CLAIMS -- yet these thought-out armchair claims are accepted!! BIG EXAMPLES OF THEIR WRONGFULNESS COME UP in statements beginning "ONLY Man can ... ". And this is in addition to THEM saying in other ways (which I am now characterizing in vague outline and obviously paraphrasing): only some 'this' or 'that' [way] will work or only some 'this' or 'that' can be the "way it is", as they "determined". They analyze any single words they choose (e.g. how we can supposedly "understand" our "will" or understand certain particular other things) as if any of these are well established concepts, when they are not; THEY then "define" other things and move on from there, both of these wrongful ways [further] making a fundamental breach with empiricism and then necessarily also with science (AND all this CAUSES CONFUSION (and it should be clear it is based on ignorance)).
Those large aspects of many, many of the philosophies are not only incongruent with science, but lead to unnecessary confusions (on larger "related" topics, like "consciousness" -- something they go on to develop ideas about, based on their initial "definitions", all that yielding the "complex" "understanding" and then also "finding" that which "cannot be understood" (e.g. the " 'hard problem' of "consciousness" " -- [a problem I see as nonexistent from another standpoint]) .
I am considering undertaking a quant + qual research by providing teachers with a questionnaire to measure their feelings and practice with regards to a type of music.
I was thinking of gathering the values from the questionnaire, and, based on the results, I will draw a sample from respondents and interview them. That is pretty straightforward mixed methods, right?
I was thinking, conversely, of meeting a small sample of participants (20-25) one on one, and handing them out the questionnaire, and based on their responses, conduct a semi-structured interview. My question is then; is this a functioning design? Is this second scenario multi-method instead of mixed methods?
I have a few questions and I am interested in your thoughts on the subject.
To what extent can the phenomena of consciousness be effectively modeled within the constraints imposed by limitative theorems? Can we devise a computational framework that adequately captures the nuances of conscious experience, or do these theorems suggest an intrinsic limitation to such endeavors?
How do limitative theorems affect our understanding of time within formal logical systems, and what consequences does this have for our subjective experience of time? Can formal models of time ever fully align with the phenomenological aspects of temporal perception?
In light of the constraints identified by limitative theorems, how can we refine or develop new meta-theoretical structures that allow for a more nuanced exploration of time and consciousness? Are there specific informal approaches that could complement formal methods in this context?
What are the broader consequences of these theorems for interdisciplinary research into time and consciousness? How can insights from mathematics and computer science inform philosophical and cognitive science inquiries into these topics, and vice versa?
How do limitative theorems inform the debate between physicalism and dualism in the philosophy of mind? Do they suggest that certain aspects of consciousness are inherently non-computable or beyond the reach of formal systems?
Its terms are different, but the theory and thought proposed are very close.
"Case conceptualization" and "psychological analysis" are the same or very similar concepts
"Psychological program" and "psychological process" are very close, attention, "psychological program" this article on the definition of psychological program is "psychological process" and "physiological process".
The first article and the second article use "case conceptualization" to obtain the psychological process, and the third article uses "psychological analysis" to obtain the psychological procedures, and they are actually doing the same things. The article "psychological program" uses a flow chart to present "psychological program", and the other two also use a flow chart to present "psychological process", The difference is that its arrow can be oriented in two directions.

Hello everyone,
I'm performing my firsts CFA in Amos and I come here with a doubt. I've tested 2 models: an unidimensional model and second-order factor model and the fit indices are exactly the same ones for both of them. How is this possible? I've thought the small sample (n = 200) could be part of the explanation, but I'm not sure at all... Any suggestion?
I understand how important it is for teachers to promote intrinsic motivation in their students. It can be challenging at times, but with the right teaching strategies, it is achievable. Would you like to share your thoughts on what strategies you think might work best in engaging and motivating your students?
I'm doing a research proposal and want to compare bilingual people to monolingual people on a dot perspective task.
- The first IV (IV1) will be language ability with two levels: monolingual (control) /bilingual
- The second IV (IV2) will ONLY be applied to the bilingual group: Ps are informed the avatar is bilingual or not (so two levels again, repeated measures with counterbalancing)
The DV is reaction times in the dot perspective task.
I am just wondering how I would go about analysing this? I was thinking an ANOVA, but as the control group are not exposed to IV2 do I just simply compare the means of all groups?
I want to compare
- Control group reaction times to BOTH levels of IV2 combined (overall RT for bilinguals)
- Control group reaction times to each level of IV2
- Level 1 vs level 2 of IV2 (whether avatar is said to be bilingual or not)
Is it best to split this study into 2 experiments or is it possible to keep it as one and analyse it as one?
Does anyone know about literature concerning this questions or wants to share thoughts?

I wanted to confirm the binding of a lncRNA to a known protein. The protein is mostly disordered except for the part that may be involved in the binding (a coiled-coil region at the end). I was thinking of performing an EMSA to confirm the binding. And then maybe I was thinking of doing a CLIP-seq to delve deep into the binding motifs and sites to see if the RNA binds to the binding domain or some other site of the protein.
My question is - is CLIP-seq something that one can perform after establishing a binding between two components? As far as I know, CLIP-seq can give more detailed and confirmed binding data concerning motif and site-based proof of the RNA binding to the protein. If not, what can be some other in-vivo experiment that can be done to check the nucleotide-level binding of the RNA-protein?
or what do you think you will offer him in the future?
