This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

My favorite problem of my own is A Modular Recursion Sequence?. It's a really great Number Theory problem that is based on a very cool principle that you guys should totally check out. :D

Finn Hulse - 7 years, 2 months ago

The principle is the Fibonacci sequence. 60 numbers and the sequence repeats.

Sharky Kesa - 7 years, 2 months ago

Exactly! Perfect! I simply modified it by only caring about the units digit.

Finn Hulse - 7 years, 2 months ago

@Finn Hulse – Maybe you should create a problem based on it except it is in mod 100 or 1000. Or I could make it.

Sharky Kesa - 7 years, 2 months ago

@Sharky Kesa – It's all yours, bro. Just mention that it's based on my problem. :D

Finn Hulse - 7 years, 2 months ago

@Finn Hulse – OK. :D

Directrix will Drive you Delirious is probably my favorite. It took the longest time for me to make it, anyways, and I'm really proud of the result.

Daniel Liu - 7 years, 2 months ago

Dude, that thing legit drove me delirious. I was literally freaking using Wolfram Alpha to rotate that freaking thing every which way. Spent a good thirty minutes. But still an epic problem! :D

My favorite problem of my own so far is C'mon, more logs?. It's part of the set Best of Logarithms. It looks like logarithms, but it actually deals with the euler totient and powers of 2.

David Lee - 7 years, 2 months ago

I love that problem! I had a great time solving it! And because you've published it here, now others will be able to view it and recognize your hard work. :D

Finn Hulse - 7 years, 2 months ago

So far I only wrote two problems on my account. I like the one about getting dizzy. I like it because it should be an aplication of plane geometry applied in space. I had no solvers that i know of. I'm on the phone and can't give the link.

Adrian Neacșu - 7 years, 2 months ago

My Problem I think this problem became Compact and kinda hard!

My Favorite Problem Is All That I Got Answer Correct !

Gabriel Merces - 7 years, 2 months ago

I still haven't even figured out a way to solve that! :D

Finn Hulse - 7 years, 2 months ago

My favorite problem is A complicated series.It may look simple but it's more complicated than what it looks like :)

Tan Li Xuan - 7 years, 2 months ago

My favourite question is Bouncing balls in mechanics. Really tests your mechanics skills . Still no one has attempted it.

Ronak Agarwal - 6 years, 11 months ago

Acc to me best problem is Complex it took me longest time to solve and i really enjoed it and i totally love this set Mistakes give rise to problems an epic set on brilliant .
