I just watched a physics show that claimed future outcomes can determine past possibilities for subatomic particles. It was Through the Wormhole - Can Time Go Backwards? (Time index 9:18 to 14:33). I hope it's ok to post that link in here it is a cable TV show, moderator kill my link if not ok...

Hi I have the educational background to do a few jobs I have seen posted as "data scientist" or "data engineer". However, I keep getting told that to get a job like that with my background, in mathematics, I need to post code examples on Github. However, I always feel like my ideas are either...

Greg Bernhardt submitted a new blog post Aiming High and Managing Distractions as Keys to Success for Science Majors Continue reading the Original Blog Post.

HI, Do you think that the way we are taught science in school from grade school to college is unscientific? By unscientific I mean we take things as true without having proof (like ohm's law). I didn't question my teachers as much as I would of liked because they use to always say that things...

I'm working on a Scifi novel, and trying to make it somewhat...scientific! Any advice is appreciated. Here's my question: I'd like to write about a situation where a body of water is purposefully kept under electric charge for years on end. This body of water would vary in size and depth, but...

Hi guys, Can anyone suggest me some of the must read books for a computer science student for learning new things and improving the programming skills! Thanks in advance [emoji3531]

I'm wondering how and in what time frame new technologies emerged and found application in the history of science. I could make several examples of those which suddenly and unexpectedly changed the world, but not the vice-versa. In particular, I'm wondering which didn't find an application or...

In the UK you would need good grades at A-levels (age 18) in maths, physics and chemistry to start a three year BSc or four year MEng in Materials science. Some universities offer an additional 1 year foundation course if you don't quite have the required grades or possibly a missing subject...

I was 302 pounds now I am 271 pounds after three weeks of consistent dieting. I am wondering why have I lost weight? I eat basically one massive tuna sandwich a day and that is it and I eat everyday at the same time which is 12 o'clock. Also how much of this weight was water weight? Because I...

Hello again people, I am wondering if it is easier to run faster as a tall person or as a short person? Please explain why thank you very much.

Hey, I’m kinda of in a crisis in my head here. I’m in the US to pursue my masters in mechanical engineering. After the introductory material science course, I believe I’ve got a greater interest towards materials than mechanical engineering. Would transferring to Material Science be a good...

Hi All, I would like to know who was the first scientist to use probability amplitudes in solving either math or physics problems. Best wishes, DaTario

We get this type of question now and then, even in the main physics forums. One such question in the Sci Fi forum is from this one: https://www.physicsforums.com/threads/what-is-the-largest-possible-rotating-wheel-space-station.950770/ So I don't know of people have seen this video from a few...

Hi I'm doing A levels now and I'm planning to go to University of Toronto next year September for engineering science, my question is what are the grades needed for my AS and A2 level to get into engineering science? My trial results are A in Chemistry and Math, A- in physics and B in biology.

Hey! I’m writing an email to a professor for research and I am mentioning some things I’ve found interesting and trying to connect them to his research but I’m not exactly sure if I’ve gotten the gist of these topics right ; like for example if dark matter and stuff effects the structure or...

Science Fictions have contributed much to entertainment and spreading awareness of issues related to complex scientific matters among the youth and the common man. It has also contributed to art etc. This has resulted in a spreading of scientific temperament and thereby has helped in adopting...

I'd have to take 3 extra courses to qualify for the minor. Is it worth it? Yes, I'm majoring in computer science and over halfway through my bachelor's. I'm learning from the current course I'm taking that the online homework - and to some degree the labs - really helps with comprehension. I...

Where are the solid-state Physics and Material Sciences overlapping? which topics?

Well I just took my midterm for Intro Computer Science and got a 59%. This is very frustrating because I've received 100% on all assignments and I feel like I am starting to get an understanding of the subject. However, this isn’t like mathematics or science where you can grind problems. It...

Hi guys, Quick background: I'm 26, in Australia, and have a degree in an unrelated field (economics). I'd like to go back to uni next year to study engineering or physics and I'm currently doing an enabling course since I didn't do any of the higher math/physics/chem subjects in high school...

Generally speaking, would it be better to pair a CS/Math minor/minor or minor/major (respectively) with physics or an additional natural science major (e.g., biochem, biophysics, chemistry) with physics? I plan on going to grad school to either pursue a physics Ph.D. or a master's in...

I'm aiming to make a list of popular science books to read along the year. Can you recommend some?

I know it's hard to predict but what are the probable outcomes? When I hear about the theory of everything in different situations it always makes me feel that we really want to believe that it will be a final fundamental theory. How could the theoretical work look like after its success...

I'd really like to know. :) Typically, practitioners of science treat the concerns raised by these disciplines in a very defensive manner. I don't mean to use "Philosophy" and "Sociology" interchangeably here, although that wouldn't be entirely wrong. In short, I'm really only interested in...

I’m curious as to what you guys thought of the movie Contact. How well does it stand up to science and physics?

Some of the most profound statements on the nature of science have come from Albert Einstein, one of the greatest scientists of all time. What do you think Einsteine meant when he said: "The most incomprehensible thing about the world is that it is comprehensible"?

I have a fun idea that I would love to get outside input on to help character building. What if the laws of our universe were beings that keep the laws in place by being them: like entropy, gravity, or electromagnetism? I'm not looking so much for how that would look but more personalities of...

In this DOS video, he talks about 5 common misconceptions on QUantum COmputing:

Homework Statement A force of 180 N is required to slide a loaded box along a horizontal floor. If the coefficient of friction is 0.32, what is the weight of the box? The Attempt at a Solution I'm not knowledgeable about any solutions able to retrieve the correct answer since the mass of the...

Looking in the mirror I just got a glimpse at the definition of a limit(Calculus) plus the beginning of calculus (Derivates & Integrals) then comes the usual goosebumps followed by a smile.And you? Which ideas are interesting for you to share?

Hello, Does anyone know of a science forum that deals with far out, controversial theories & ideas? This would be similar to the science fiction forum here at PF but may even be more outlandish, however postings would receive serious consideration. I have made some simple animations that I...

The Trump administration says the EPA was using too much science in Obama's Clean Water Act rules. Longish Science magazine news article here.

A recent thread, which was quickly shut down, provided looking at the user agreement for PF as the final answer. The attitude is people who don't like PF and want to discuss their free energy solution or whatever can go elsewhere. Very true. I understand why people here may not want to spend...
