An Olympiad (Greek: Ὀλυμπιάς, Olympiás) is a period of four years associated with the Olympic Games of the Ancient Greeks. Although the Ancient Olympic Games were established during Archaic Greece, it was not until the Hellenistic period, beginning with Ephorus, that the Olympiad was used as a calendar epoch. Converting to the modern BC/AD dating system, the first Olympiad began in the summer of 776 BC and lasted until the summer of 772 BC, when the second Olympiad would begin with the commencement of the next games. Thus, Olympiad N for N less than 195 started in the year

BC and ended four years later. For N greater than 194, Olympiad N started in AD

{\displaystyle 4\times N-779}
and ended four years later.
By extrapolation, the
1st year of the 700th Olympiad began (or will begin) around June 21, 2021.
A modern Olympiad refers to a four-year period beginning January 1 of the year the Olympic Summer Games are normally held. The first modern Olympiad began January 1, 1896, the second January 1, 1900, and so on (the 32nd began January 1, 2020: see the Olympic Charter).
The ancient and modern Olympiads would have synchronised had there been a year zero between the Olympiad of 4 BC and the one of 4 AD. But as the Julian calendar goes directly from 1 BC to 1 AD, the ancient Olympic cycle now lags the modern cycle by one year.
Recently I gave my Astronomy Olympiad. There were some questions of descriptive type. If you all don't mind I would like to discuss them here. :rolleyes:
hi everyone
i'm a 17 year old 4m india, who is taking part in the national phy oymp,
leading to the intl. phy olympiad.
how do i prepare 4 this ?
pl reply soon as i have only a couple of weeks 2 prepare.
1. Polishing of the surfaces in contact beyond a limit increases friction because:
i)irregularities are increased ii)surface projections are sharpened iii)area of actual contact is increased iv)none of these
My ans. (ii)
2. A chain is placed on a frictionless table such that 1/5 part is...
1. For a gas if p and v denote the co-efficient of volume expansion at a constant pressure and coefficient of pressure at a constant volume respectively, then
1)p>v 2)p<v 3)p=v 4)p=0 and v=0
2. The horizontal component(H), vertical component (V) and total intensity (I) of the...
I found past questions here:

Were can I find the answers?
Also, were can I find similar kinds of questions?
Thanks.
Hi,
I did the Olympiad this week and I found it very hard. Does anyone know what the percentages needed for the awards are.
Also can anyone remember any of the parts of Question 1 as I found it very hard and i wanted to ask my neighbour who is a physics lecturer about it
Hello folks,
I am quite new to Olympiad level problem solving :smile: , which is why I am considering buying Paul Zeitz's "Art and Craft of Problem Solving". Does anyone have the solutions? I have heard the solutions are in a separate Instructor's Manual, does anyone know how someone can get...
Hey,
So I'd like to do the International Physics Olympiad (IPhO) next year, and I was wondering what any of you wonderful physicists would suggest as adequate preparation, particularly those who have done IPhO before. I live in Ontario so I've looked at the University of Toronto Prep...
The 36th International Physics Olympiad was held at Salamanca in Spain from July 3-12. 342 contestants from 77 nations participated.
India placed 6th with 5 medals(2 golds, 2 silver and 1 bronze).
Piyush Srivastava(17) from Allahabad and Sameer Madan(18) won the gold medals for India. In fact...
i have 69 distinct positive whole numbers between 1 and 100. i pick out 4 integers a,b,c,d. prove that i can always pick out 4 integers such that a+b+c=d. can this always hold true with 68 positive integers?
The following is a problem I got in a Maths Olympiad, I had to solve it without a calculator, although I couldn't solve it:
sin 1 + sin 2 + sin 3 + ... + sin 90
If anyone could show me how to solve this I would really appreciate it.
hey, I have a tough time cracking this one
The other problem is:
Imagine a glass tube with steel rings around it which have a conductancy rho and a half diameter of R. they are spaced with a distance H.
inside the glass tube is a much smaller glass tube. Through it you drop a magnet with mass...
I belong to an organization named Science Olympiads. One event is named Bottle Rockets. The object is to shoot a 1L soda bottle into the air and put as much time as you can between launch and touchdown. My question is this, what is the best ratio of length for the nosecone on a rocket? It seems...
