Olympiad Definition and 158 Threads

So I've been told recently, that I will be participating in the "British Olympiad in Astronomy and Astrophysics Competition", which I am really excited about. I took the British Physics Olympiad Paper earlier this year, and feel like I could've done better.So because I am quite new to Astronomy...

Homework Statement Let's suppose we have a [cuboid](http://en.wikipedia.org/wiki/Cuboid) of dimensions ##a \times b \times c##. We put it on an inclined plane of an angle ##\alpha## so that only one edge of length ##c ## touches the plane. In time ##t = 0 ## the cuboid doesn't rotate. Let the...

Dear all, this may seem like attention-seeking of some sort but recently I competed in my country's Physics Olympiad and vastly under-performed. It may sound like I'm making excuses but I largely attribute this to a panic attack I had at the start of the test that led me to be unable to perform...

5. Point Q is 3m above and 4m to the North of Point P. Ignoring friction how much energy does it take to move a 5kg sack of potatoes from point P to point Q? These are multiple choice questions of the exam, so in the mark scheme it only says: A, B ... The question paper can be found...

Hello! I am new to this forum as you can see.I wanted to know that how should I start preparing for the National Physics Olympiad,from the very begining.I do know some MECHANICS but it is not enough to crack the olympiads.What should be my strategy,How should I proceed. P.S-I was quite...

Hi.. I take a high school physics Olympiad. Could you please tell me what the best physics video channel on YouTube or other sites ? I'm looking for videos that gives an overview to an advanced problem (It can be IPhO level) and guide to the solution step by step..

I'm trying to pull some old Olympiad questions for some students, but I can't get a handle on this one. I'd really like to include it, though. In answering general knowledge questions (framed so that each question is answered yes or no), the teacher's probability of being correct is A and a...

I realize questions about Olympiads have already been asked till death, but I think I haven't seen mine popping out anywhere, so here goes. Does anyone have any ideas on how to prep for the practical round of a physics Olympiad (not the IPhO, a national one). I can get papers for the I & APhO...

Homework Statement An experiment was conducted to investigate the time it takes water to pour out of a can through a little hole and the amount of water in the can. To find the dependence on the size of the hole, five large cylindrical containers of water of the same size were emptied through...

Is it advisable to use Serway-Jewett Physics for scientist and engineers for iPHO prep? What about Young Freedman University physics?

After this summer I'm starting my 11th grade. I would like to study physics at a top university (UK or US). But at the moment, I don't have any physics or mathematics olympiad prize. Do I need an International Olympiad to go to a top university? I'm confident my baccalaureate grade...

what books should one follow if he or she gets selected and want to participate in International Physics Olympiad?

Hello everyone! My first post in this seemingly wonderful forum! Anyways, I an currently an undergrad and throughout my high-school career, I have honed my problem-solving skills very well. I have done very well on the olympiads, Putnam, IMC etc. Now that I am an undergrad, I still believe that...

How can I go far in the national mathematical olympiad? Do you need to be born with an insane IQ, or born a genius or something like that? Any tips about how I can increase my problem solving skills if it's even possible? Examples of problems you will have to solve in the second round of the...

I've got a Physics Olympiad coming up in a couple of months. Here is one paper from it: http://www.physics.ox.ac.uk/olympiad/Downloads/PastPapers/BPhO_Round_1_2013_prt_2.pdf If you would look through a couple of the questions I'm sure you'll get the flavour. I'll reproduce one of them here...

International Physics Olympiad (Preparation)? Hey I'm a Danish student, who will start 11th grade after summer. I intend to get to the International Physics Olympiad 2014. I'm familiar with almost the whole syllabus, but I'm not strong in calculus yet (I know basics of differential...

I realize this must have been posted to death already, but brushing over that: What's the best way to study for the (British) physics Olympiad? Feel free not to answer all of the following points (I've arranged it this way for clarity): Firstly: would it help in the regional finals to have...

(x,y,z)∈R^3 are points that lie on the plane x+2y+3z=78, and lie on the sphere x^2+y^2+z^2=468. The maximum value of x has the form a/b, where a and b are coprime positive integers. What is the value of a+b?

Okay, guys. So the thing is I'll have to attend to Physics national olympiad (not a big country, so not big deal), but, when looking at last years exercises, I realized, that I have no idea how to solve them. Heck, I don't even understand the solutions, that teacher gave me! What I'd like would...

Question is : If m,k,n are natural numbers and n>1, prove that we cannot have m(m+1)=kn. My attempt : Using induction: If m follows this rule... m+1 must follow it .. so (m+1)(m+2) = kn Since every natural number can be expressed as the product of primes, it follows that (m+1) and (m+2) are...

Hi guys, I have Feynman lectures, University Physics, and Irodov problems in general physics with solutions. How do I make use of these books? Firstly, I must say that university physics textbook is rather simple to go through, but I've heard that Feynman lectures are better for physics...

Ok, so this problem looks like an induction problem to me, so I used that, but I only got as far as the induction hypothesis. The hint says to use the pigeon hole principle. I'm not sure how to use that for this problem.

Hi, I'm new here, and I hope someone could help me out. I'm in grade 12, and plan to write the preliminary exams for the olympiads this year. The problem is, i have only around four months till this date. I went through a tough time in 11th as I switched schools, and in general my grades fell...

I have always loved math and have done independent theorem-proving and research. However, I have had absolutely no olympiad training but it seems that the math olympiad is quite important in applying to universities. I have started to do some of the questions myself and find that I progress...

Not sure where this goes, but since it's an education thing, I figured here would be the best place. Hi all, I'm planning on sitting the British Physics Olympiad A2 challenge in a few weeks and I was hoping to see what people thought about it and see if anyone here is either doing it this...

Q. Sixty four squares of a chess board are filled with positive integers one on each in such a way that each integer is the average of the integers on the neighboring squares. (Two squares are neighbours if they share a common edge or vertex. Thus a square can have 8,5 or 3 neighbours depending...
