Hi!

There have been a number of contests on Brilliant on a wide variety of disciplines including Calculus, Inequalities, Mechanics, etc.These contests inspired me to hold an interesting marathon, namely, the **Brilliant Proof Marathon**.

Unlike regular problems posed on Brilliant, which usually require only answers, we also need to practice proof problems, and make our proofs short and elegant.

I shall be posting a proof problem or two every week. The one who posts the maximum number of shortest and most elegant proofs shall win.

This marathon would commence on 9th of June.Stay tuned and have fun.

Honors: Three best proofs of a given problem will be awarded with status of *Nice one* , *Excellent* and **From the Book**.

Sorry guys, I'm am leaving brilliant for a while. I'm shifting this marathon to 8th of July. I shall get active on July, when my RMO preparation comes to an end.

There's even a chance for the competitors to pose problems. If you want your problems to featured in the contest, feel free to post them here. Follow the given guidelines:

Refrain to pose problems which are seemingly easy and generally follow a short path.

Do pose problems which are likely to have a tedious approach by most of us.

If your problem is liked, it shall be selected for the

Brilliant Proof Marathon.If none of us have a solution for the problem, the problem poser shall post the solution in 15 days of posing the problem.

Most importantly, you should have the solution to the problems you pose in the marathon.

Pose your problems in this note, without solution.

@Harsh Shrivastava and @Nihar Mahajan, Feel free to enrich the contest with your inequality and geometry problems.
