Cheers guys We were given a science project to preserve the following using only household items for 5 dats...Chemicals may not be used as well as any external power source like an outlet: Bread Milk and a mystery item which would be presented to us on the day. One of our teammates...

I was thinking, and somehow I had this little "thought experiment" type thing relating to objects and the speed of light. (This is just my thoughts, I don't know if it's correct or the validity of my assumptions, etc) Imagine you're in a (large) room, and that the effects of friction, air...

I have been learning a lot about STEM focused schools (sixth form and high school) recently because I have got an offer from a Mathematics specific school myself, in London. I noticed that there are very few in the UK at all. I know that it is a very small country in comparison to the USA but I...

What are your thoughts on this excerpt from my chem prof's textbook? I have a few problems with the beginning of the text and a huge problem with the bolded statement. I understand the intentions of my teacher - structure - is highly important in chemistry. Not so much emphasized in general...

Is there any forum exist where we can express our own thoughts ?:confused: I will be Thankful to you.o:)

I hope that the title is a bit better than my last one... I would appreciate any input on items I have made or will be demonstrating as it should be about 30 minutes long and a balanced programme. Background... I am in training as an Assistant Beaver Leader in my Sons Beaver cubs scout pack...

I'm currently half-way through my third year as a physics major, and I'm starting to reconsider my initial plans of attending graduate school. It's not so much my grades are bad (cGPA ~ 3.5, 3.8 so far in my third year and am will likely maintain this until I finish), but I'm just not at all...

I am totally fed up with not having had the use of an oscilloscope for many years. It has been very frustrating on so many occasions. I need one. So, my options are (and I only want to spend minimal cash, of course): An ancient eBay analogue scope for something around £100, a PC based one or a...

The only reason we require DHCP is because we don't have enough IP addresses to give everyone a static IP address, right? Does that mean that we will soon lose the ability to be anonymous on the Internet? Does that mean that everything we do will be definitively tracked to our IP address? I...

Colleges look at SAT scores. There's really no way around that. But overall, how important are they in comparison to other criteria on college applications? If one only got around an 1800 on the SAT, but had hundreds of hours of volunteering in their future career field, and had a 4.0 GPA, did...

Dark matter build up near or inside Black holes, thoughts ? I can see it making a real mess of the motions and energies of normal matter in and around a black hole or other very dense body that confines dark matter to a small adjacent region. Unslowed by frictional forces...think angry...

So I in a couple more months I will be completing my Gen. ed. requirements(which I'm so happy about!), but now I am wondering if I should fill all my available time slots with all science and math courses. This coming semester I will be taking Intro to Probability Theory, Numerical Analysis, and...

What is the mind considered to be in physics ? Is it just a collection of thoughts ? And has there ever been any studies done on the mind and matter manipulation ? Appreciate all replies. Physics is Phun

I know little about what actually comprises a physics program, but I wanted to know what people had to say about this major. I would like to know general things like the difficultly relative to an engineering major, what kind of careers you can get into with it (I hear its rather broad) Is it a...

I have many ideas and thoughts that I want to store. Many are insights about some particular topic. Ideally I would want to write a book but that's too far-fetched (is this how writers get motivated to write books?) I don't want to write in a notebook or something. I think it's temporary and...

Hi all I'm feeling a bit lost here, but hopefully someone might be able to lend some insight. I am an accountant. I've been working at a small firm for about 4 years, and in that time, I have also gained my CA (Professional qualification). But I got bored, and decided to take a year out to...

Hey everyone! I spent a lot of this summer developing a personal website for myself. It hosts some computer games I’ve developed as well as some other programming projects I have done as well as blog articles. The website is: www.clintonmorrison.com You can play the games I created at...

When we think about first world nations and world leaders in politics, ethics, economics, and science, we think of Western nations that are built on democracy, human rights, and freedom. But now we are facing a new situation where the prospective new world leader will spread its influence while...

I had a guy recently ask me how he can become more disciplined. After I gave him some advice, I checked his history and he posted a lot to "Nootropics." A quick wiki search says it is used to treat "disorders as Alzheimer's disease, Parkinson's disease, Huntington's disease and ADHD."...

I'm not a gamer anymore (my xbox broke two years ago and I never replaced it) so I'm a bit out of touch. However I've read a bit about the new xbox one and I have to say I'm distinctly unimpressed by the direction modern consoles are going in. Any thoughts from gamers or otherwise? For me the...

https://www.youtube.com/watch?v=QAEkuVgt6Aw I saw this trailer on ultra screen in 3d and I was captivated. No doubt a very well made trailer, but still I'm pretty stoked for the movie! Even if it just reaches the success of the first, it's been a nice series reboot.

Hello, I am working on a regenerative wheel hub design for an EV. This is not a regenerative braking system, nor is it a violation of the conservation of energy idea. The idea encompasses using the rotating mass of a wheel to provide a trickle return charge to the battery pack as a wheel is...

Has quantum physics "proven" that thoughts become reality? This is not a homework assignment. When I go to the homework section, none of the links fit because this is a quantum physics question and it’s neither undergraduate or high school related. If this is not the appropriate forum, please...

h''(t)=-\frac{1}{h(t)^2}, h(0) = h_0, h'(0)=v_0 The first step is to, I think, reduce this to a fist-order problem: h'(t)h''(t)=-h'(t)\frac{1}{h(t)^2} --- Multiply both sides by h'(t) h'(t)^2=\frac{1}{h(t)}+c_1 --- Integrate both sides 1/h'(t) = \sqrt{\frac{h(t)}{c_1 h(t)+1}} ---...

Recently it occurred to me that my mental image of the CMB radiation, gleaned from a range of popular science books, was probably completely wrong. I set about some thinking. The following notes outline my thoughts so far, and I would appreciate the comments of others more knowledgeable than I...

All right, so I've started my Joyce phase with Ulysses, but as I like to read a few books at once, I was thinking of picking up Finnegans Wake as well. It is both famous and infamous for its difficulty, so I'm going to borrow Joseph Campbell's A Skeleton Key To Finnegans Wake from the library...

"The future of Radio Astronomy" (your thoughts) Hello all, I'm doing an extended project on "the future of radio astronomy". And I would like to know people's opinions on the "future of radio astronomy" and what advancements the field of radio astronomy is expected to make in the future...

Is this sufficient?

Sonofusion, Cold Fusion, Crossfire, IEC, MC, you name it. I'm a young scholar interested in the various kinds of fusion and where they stand in terms of validity, possibility, practicality, etc. I'm mostly curious on what people think of the kinds of fusion out there and what science has...

Second thoughts on physics PhD--Engineering masters/PhD or job? Hi all, I recently started a funded MSc-->PhD graduate program in physics at a mid-top tier 2 university, and I'm having concerns regarding my future career prospects. My initial plan was to finish the PhD, but now I'm considering...

This is a very common topic especially regarding the apparent slowing down of time, the twins paradox etc. I have come across the figures for a muon and the relativistic effects that allow it to reach the Earth's surface despite its very short life. The relevant transforms show length...

Hi! I'll be covering the above book next semester and was wondering if there is anything I should be particularly aware of about thermal physics. -aLearner

Hi, I am currently a freshman in college and my major is Computer Engineering. However I am having second thoughts about this major and wanted to ask you guys for some advice. I like working with computers and technology and was wondering if any other majors related to this. I have looked into...

Today I received my mgre subject test scores and had a complete panic attack. I knew they weren't going to be phenomenal, but they were definitely worse than expected. I have a severe problem taking standardized tests, and I knew this long before I took the exam. I know I am more capable than...

Hi, another thread talking sbout QM interpertations sparked my interest on the subject. Now let's assume that we have electrons in a box, it could be anywhere inside. And let us assume that the electrons do indeed have unique positions instead, that each electron has a set of three continuos...

I have been thinking, weather balloons can go quite high (some up to 1000ft) so would it be possible to take 4 or 5 weather balloons and attach them to the corners of a frame. in the centre of the frame would be a rocket ready to launch at a set altitude. the only problem i can think of is...

I am 18 years old and really wanting to become a engineer, But I feel I may not have the mathematical aptitude for it. In your experiences can anyone become a good engineer, as long as they put in the time required? I believe that I am creative, hard working and quite enthusiastic...

I am currently enrolled in an introductory Systems & Signals Processing course. The problem is, this has thus far turned into a series of lectures on the nuances of the Fourier Transform, i.e. special cases and difficult problems. Why am I complaining? Well, in his syllabus, he lists a...

Hi all! I'd like to ask for some opinions on a book. I'm currently taking an undergraduate course in topology. We're using the book A Combinatorial Introduction to Topology, by Michael Henle, and so far I have mixed feelings about it, feelings that my class and professor seem to share. 1...

Hello everyone, Little back story, so when I began college as a freshman I thought I wanted to become a doctor. My sister already being in med school it seemed like a challenging and rewarding career which could ultimately make me a lot of money. However speaking with my physics teacher...

How do you think of numbers when you're doing math? I particularly feel like sometimes we get to close to acting like computers. We just scan through a list of symbols and compute another list of symbols that makes sense in a certain context. We hardly ever think of things concretely and how...

Hello All, I am a senior computer engineering student at a small university in West Virginia. I am in the process of applying to graduate school for a masters in computer science next fall. I have picked my target schools and contacted each department. I am looking at: Carnegie Mellon...

Personally I think the equation greatly overestimates the number of possible intelligent life in the universe... But then again all I have is a college level education. Can anyone explain?

http://www.arachnoid.com/psychology/index.html I was just wondering what people here thought about this article.

I just finished undergraduate E&M, the class was using the Young and Freedman University Physics, but I decided to go with the Grant and Phillips Electromagnetism and it worked pretty well. At UIUC Physics III or modern physics is broken into two parts, thermal and quantum. For the quantum...

http://www.reuters.com/article/2012/05/16/us-paralysis-robotics-idUSBRE84F1CM20120516 This is a remarkable achievement by the scientists. Now, we don't need limbs any more? :P I wonder how did the scientists find out where to connect each electrodes? How did they know which portion sends...

Hi Everyone, I'm doing the final year of my bachelors and I'm going to have to make some important decisions. There are things I have observed but I'm not sure whether they are true in general. At the moment I am majoring in optoelectronics (laser physics + electrical engineering). I enjoy...

Hi all, I am in the process of wrapping up my degree in Applied Physics with emphasis in electronics. The program has required me to take several courses from the electronic engineering department, which I have thoroughly enjoyed. I have done some planning, and it will take me one extra year...
