Science Definition and 990 Threads

I'm reposting this here because it raises a fascinating kind of vulnerability (new to me). It is a vulnerabililty of any science using software for analysis to a common-mode error. The thought that 40,000 scientific teams were fooled is shocking. It is a good post, it links sources both...

No question this time, just wanted to share this. I searched the posts and only came up with an eleven year old thread, so I thought it might be time to post a new one. I particularly found the aspect of Methane fuel interesting...

In the current Verizon ad featuring LeBron James in a physics lab, there is an instrument displayed prominently in front of each student. What is it?

Hi guys. I'm a junior in high school and am debating on which field to pursue. I know it's a bit early for me but I've always wanted to go into a career with computers and just wanted some help. I'm sure similar questions have been asked before but if you would be so kind as of to answer some of...

It is often said that science is a 'model' of reality out there. I think this statement is wrong. It presupposes that there is a reality that is beyond 'modelling'. Suppose, someone really finds out the reality 'as it really is'. ( I am not saying there surely is). She would first of all...

I want to become computer expert in all aspects I know programming I study Electrical Engineering in university and I love computers I want to know computers in basic level If I want to learn basic about computers what work should I do? between data structures , operating system , computer...

Hi I recently skimmed through a book called the Structure of Theory. It's a book about what kinds of theories exist. I would like to learn more about this. What books and websites can you guys recommend? I would prefer a resource with specific examples of what kinds of theories exist in...

Hi, Here's my dilemma... I have been accepted into both courses. I applied for Engineering first but am afraid I am not smart or driven enough to complete it. It is also 3 hours away from home, therefore, I would have to move out but unfortunately since I don't have a job my Mum has offered to...

Sharing this funny video from the ASAPScience channel:

Hello, PF! I had been meaning for some time already to start a thread like this, in which we can share our personal, technical (math, physics, engineering) library (as a list or in pictures too), and also recommend your favorite textbooks or handbooks. Here is my collection so far, as a junior...

Hi guys I'm going to study CS in college this fall, but don't know if I need to upgrade my computer or not. I understand you need a lot of computing power for some heavy caculation but just wondering is that going to happen at the college level courses. My current set up is a pc with i3 3220...

I'm currently reading thermodynamics which is only the second volume of all the physics course that I'm planning to read. So for the math in it is just killing me literally. Mechanics was relatively easy but this subject is just too freaking hard. All these partial differential equations and...

Therefore this thread, to see if there any ideas that didn't cross my mind yet.

Hi, Does an Atom's Type have to do with the number of protons and neutrons it has? Or are they completely unrelated? Just curious. Thanks :)

Are there any books that go into detail on how research in the physical sciences works? For example, analyzing whether a hypothesis is falsifiable or not. I want to be a physicist, and I want to know how science is done right in order that I can be a good physicist/scientist. Thank you.

I am currently still a high school student but i will be going to university next year. I've long decided to take a double major of physics and computer science. I can get a scholarship for undergrad. But my question is about after I get my Bachelors Degrees in both computer science and physics...

Greetings all, I am quite new to this forum so please forgive me if this is on the wrong thread. I recently purchased some reflective paint which sprays on clear and appears white/silver once light hits it at night. However I am looking for a type of paint that is invisible to the naked eye...

Computer science major here. I recently completed calculus I, II, III. Now I know that I'll probably be required to take linear algebra. So far, I expect to do some Gaussian elimination (assuming I know what a row echelon is). What else should I expect from linear algebra?

Hi! I am physics passionate and I have always tackled a bit of this and a bit of that in other sciences. I have recently found out that there is something called forensic science (like in CSI stuff). No, seriously, I found out that this is a thing like two weeks ago, so I want to see what's with...

Very funny and insightful video:

Have you ever felt like you want to throw everything away? I'm mean, for those of you who are PhD's, have you ever felt like just leaving you degree and go and do something else? Would be nice to hear some good reflections.

At the end of the movie about a robot boy who sleeps a long time under water ("AI"? by Spielberg?), sentient beings seemingly made of light appear. That's what I remember anyway. Is that within the possibilities of known science? Can light particles behave as organized matter in and of...

Hello everyone. I want to be interest in rockets. How I begin? Which books are I have to read? I'm also interesting with aircraft. Especially unmanned aircrafts. I have a little bit aerodynamic infrastructure. I'm waiting your answers. Thank you.

Recently I had a thread in PF and also participate in another one and somehow time after time the discussion touches on a few important points that deal with both history, politics and also a lot of stereotypical thinking about the world both how it's now and the way it was in history. We live...

Hi, I've been really looking into going back to school for awhile now, and I don't know exactly what I want to do, however I can't see myself doing anything not related to math and science. The circumstances in my life are progressing in a manner that would make it financially feasible and...

Hi there, Since Science has a rapidly changing knowledge base and expanding relevance to society. Can you give me suggestions or innovations I can use in my science class to cope up on this.

I'm sorry if this is a bit of a mundane question but we all do impulsive things when we're anxious. I may get a B+ in General Physics II and Calculus II this semester (2nd semester freshman). I know I am capable of much better, and to be honest, I was very bogged down emotionally/psychologically...

Hello fellow PF'ers! I have been conversating with a strongly religious character for some time now, and thought i'd present some of his arguments to you. I have myself tried to explain the basics of the problems, but maybe some of you can have a laugh and go into further details as to why he...

To what extent is the term infinity used in the physical world. When talking in terms of mathematics we can have a set of all natural numbers called an infinity, then we can have a value that comes after this set of infinity (lets call it 'a'). After 'a' comes 'a+1' then after this set of...

Hi, I'm applying at a swiss univerity (EPFL) and I already have to pick my major. Here's the thing : I currently love programming. I enjoy finding beautiful ways to solve math programming challenges on the net. (I code in Python). I love automating stuff with programming. I love projects : I...

Hello again PF! I was accepted to an REU for this summer. I was just hoping to get some nuggets of good advice for what to do to be successful. Only thing I keep telling myself is to work HARD so I can make a good impression and hopefully contribute to a successful project. Any good advice...

Hi I have been admitted to University of Toronto[ Trinity college] and McGill University as an international student for physics major. I am planning to do double major in computer science and physics. I want to know which university is better for these subject at an undergrad level. I have to...

Hello people, I am currently in my third year of Physics B.Sc., and I will prospectively get the B.Sc. Degree in half a year...if I just knew in which direction to go. I wonder if it I can get into cognitive science and machine learning from that position. Which physics bachelor theses do build...

I'm sure this is elementary for this forum, but can someone help me figure out if my son's science fair project results are correct? He rolled his toy car, with and without weight added, down hill and measured the time to get to the bottom of the hill and the distance traveled once the car hit...

My situation is this: I graduated with a B.S. in Computer Science in 2011 and have been working ever since. Now I'm thinking of returning to school for physics, with the ultimate goal of going to graduate school for physics. I think it's safe to assume I am not well prepared for graduate...

I've been hearing of many athletes coming forward to donate their brains to science when they die. Curious with most of us being involved in science and its progress has anyone here made plans to donate their body or an organ to science after they die? Why not? Let's do it!

Hi, just came across a video on CNN showing how to make water behave like it would in space: <link to video deleted> My question about that video is: what height do i need to get a free fall time of 10 sec? best regards

If a job listing asks for a degree in computer science, can someone with a computer engineering degree apply for that job? assuming the computer engineer meets all other qualifications

I heard that if Aether was real it would simplify many things in science, what exactly would it simplify?

HO! I am new here. HUZZAH! WOOOOOOOOOOOOO!

Homework Statement An electron travels at 0.422c. Calculate the following. (a) the relativistic momentum kg · m/s (b) the relativistic kinetic energy J (c) the rest mass energy...

I am posting this here instead of "Science and math textbooks" because I am looking for suggestions on an easy reading but educational book, not a workbook. I am by no means an expert, but I have a solid backgound in math and physics from college (Engineering), as well as self-study with...

I am not an expert in the field, but intuitively I think that a resume with both math and computer science has a lot of impact. I also think that math can help me understand computer science better. Next quarter, I am planning to take classical geometry, so I am just wondering if this class...

Hello! My hobbies are tinkering on my computer and mathematics. Physics is not bad but I do not love it like I do mathematics. I like the logic and analytical skills that it requires. I like solving problems. I recently dropped out of Aeronautical Engineering because I simply did not like over...

My friend is a 7th grade teacher and has asked for help finding resources she can share with her students. Web sites, videos, books, etc. appropriate for a Jr High/middle school level. Specific topics she'd like to cover would be: time travel economics (socialism vs capitalism - real economics...

This is an article I just found out about. It deals with computer science on about half of it, but the most interesting discussions concern educational values. Here is the article: https://www.cs.utexas.edu/users/EWD/transcriptions/EWD10xx/EWD1036.html I would like to know others' thoughts on...

Greetings Forum Members, I am quite new to this & this is my first post. To tell you guys a little bit about me I am a magician that creates effects and I figured that when I am stuck I should go somewhere and ask people that are smarter than me :-). First Question: Is there any kind of...

I normally would have put this in the grad school section, but the question is more pertinent to choosing a career path. So basically at one point in time I was in a graduate program. I left pretty early due to funding issues as well as some personal issues that I needed to resolve. I ended up...
