Hello, My understanding of the scientific approach when faced with an unknown sequence: Hypothesis: There is an order/signal/bias/code = Goal to achieve Null hypothesis: Absence of bias/order/code = Equal Probability = Target to destroy. Science tries to break the code. In order to prove the...

Looking for suggestions on books (or other learning material) that will help me improve my skills using Python for scientific computing. I am comfortable with Python programming (syntax, conditional statements, loops, etc.), and use it for data analysis in my undergraduate experimental physics...

I've been logging daily temperature and humidity data for two years now. In the end of each year I will put a graph like this Those are daily minimum and maximum temperatures. But I was wondering, if all this has any scientific value at all. I've been using WS2300 weather station for these...

I've been up all night writing and I want to go to bed, but for the life of me I can't find the paper or even the title of the paper that has been referenced in another paper. All I have is... M.A. Margulis, A.N. Maltsev. Russ J Phys Chem, 42 (1968), p. 1412 Which should be enough to locate...

Hello and good day. I am currently involved in research that seeks to utilized a Walker Scientific power supply and magnetic. The system is old but functional. We seek to utilize the magnet in order to conduct some low temperature experiments. We need information on this power supply, of which...

This is the provocative question posed by Sabine Hossenfelder in her article in Forbes, covering the ongoing debate of inflation critics like Paul Steinhardt (once one of the theory founders) and scientists who develop models of inflation. Link to her article...

Hi all, I am a professor in mechanical engineering and I have several master thesis students and I am facing the problem with the quality of their thesis. Especially, most of the thesis I have to correct are often very long because they are rich in useless information and lack of literature...

Is there scientific studies that confirm that a race or ethnic group is physically superior to any other? I think we can examine sports records can make some judgement on what type of groups of people are superior in each type of sports. But I don't know how you would go about judging who is...

I tried a search for this first and had negative results so I thought it might be helpful. Google has launched a new https://www.techsupportalert.com/content/google-launches-new-dataset-search-engine.htm feature that enables laypersons to retrieve highly specific results from millions of...

I'm going to assume there will be some strong options on this piece! https://www.theatlantic.com/science/archive/2018/04/the-scientific-paper-is-obsolete/556676/

I like to start a graduate program in scientific computing within the next 4-5 years, once my kids are a little older, my wife finishes her degree, and I have more money saved. In the meantime, I’m not going to waste time. Using the MIT challenge completed by Scott Young as inspiration, I’ve...

Hi, I wanted you guys to tell me whether you like this idea I had and if you have any ideas on the implication of it, and whether it would work as I describe it or not. So, in this world I created, there is a basic understanding of physics by the scholars, but most people don't even understand...

I am studying the scientific method and have come to the following conclusion. Since X -> Y does not imply X is true (or real), it is impossible for the scientific method (SM) to prove that anything is true. So like mathematics, the scientific method builds knowledge on axioms which cannot be...

I want to casually discuss possible scientific theories but it seems like all forums prohibit that type of discussion...

I find both subjects interesting, to the point where every night after putting the kids to bed, I spend a few hours self-studying, but I wonder if going back for a master's degree would be worth the effort. I know that if I want to do professional work in either of these two subjects I'll need...

Hey. So I was curious what are the main differences between: 1) Fiction: Time Loops, like the one seen in Groundhog Day or Edge of Tomorrow And 2) Scientific: Closed Timelike Curves: Which occur in certain solutions of General Relativity. Note: Sorry, a lot of the time before I thought time...

I know this publication is not peer reviewed, but when I saw this article it was exactly the same way I came to “understand” the twin paradox myself. I literally did this exact calculation (with a different gamma value). So I was wondering if the article was valid. If it isn’t, where isn’t it...

Hello! I'm very interested in physics, and relatively new to it. I'm doing a degree in Engineering but interested in shifting the Major to physics. I'm requesting suggestions about scientific paper that EVERY physicist must read in order to get a certain command on the subject. I mean by that...

When I asked this question in another forum, some people argued that scientific and mathematical discoveries are born out of curiosity and a way to explain unknown elements that surrounds us. Others say it comes from originality. In my opinion, I think it does come from curiosity, but you have...

Hi Everyone, My college runs a student run academic journal in which students read and write a review of a topic in physics and then some are selected for publication. I am determined to get mine accepted but am struggling to pick good topics. Topics must have research being carried out...

The Scientific Method says that if a theory disagrees with observations, it has been falsified (according to Karl Popper). String theory predicts that spacetime is 10-D, but it is observed to be 4-D. This is a wrong prediction by the theory. So string theory is falsified. String theorists then...

Of interest: New York Times - October 13, 2017 Fraud Scandals Sap China’s Dream of Becoming a Science Superpower By AMY QIN BEIJING — Having conquered world markets and challenged American political and military leadership, China has set its sights on becoming a global powerhouse in a...

My son is taking a chemistry class in high school, and he was telling me this morning that their teacher had taught them there was some kind of fundamental distinction between scientific laws and theories. He said the teacher had told them that laws are just fundamental regularities observed in...

Hello, I have been wondering how it is possible for us to encourage international scientific research collaboration. I mean what can governments, normal people and research groups do to encourage it? I value your thoughts. Thank you.

It would save time if we could just say "it's the CHIDIP effect again." So, what a sciencey name for the following: The first one is: You never run out of chips and dip at the same time? Then: There ten hot dog buns in a package but hot dogs come eight to the pack?

---I am not sure in which section i should post this question , so if it is wrong section kindly move it to the proper section ---- I am really confused to draw a clear line between what is science and what is not . I know science has some characteristics which differentiates it from...

An interesting article in Ars Technica on p-hacking vs deep data dives: https://arstechnica.com/science/2017/04/the-peer-reviewed-saga-of-mindless-eating-mindless-research-is-bad-too/ We shouldn't look at data trying to find something interesting but should instead have a hypothesis in mind...

Is there anywhere we can rate each (scientific) journals? Publication ethics is for both sides. Not only authors should follow some ethics, but editors should also follow. There are some journal editors not following praction ethics.

I am going to be writing an argumentative essay on the topic, and was wondering what people think about ideologies and their influence on the sciences. I have not been on the forum before, but from what I have seen this seems like a good place to get some interesting feedback. Thanks in advance...

This is in the way of a rant, but I am posting it here as it relates to education and to encourage you educators to do a better job. :wink: I recently bought a well-known manufacturer’s LED light bulb at a home center. I was curious to know the spectral output of the bulb, so I emailed customer...

Hi, I have two degrees. A BA in physics and a master's in computer science. I've taken more than 30 hours in upper level biology courses and a decent number of hours in mid level chemistry. One thing that I can attest to is that all of the disciplines have a different feel to their respective...
