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.

Hi Azhaghu, good question! We had a beta version up and running for a few weeks in the summer of 2012, and then we took the site down for a while to work on making it much better. We consider October 28, 2012 to be our official launch date.

Staff - 6 years, 3 months ago

Wow ! My B'day is on the 20th ! Haha , I am older than B'ant by 8 days :P

Anyway , thanks for replying ma'am :)

- 6 years, 3 months ago

So you were born on 20th october $\huge 2012 \ ?$

Because you're saying that you're 8 days older than Brilliant !!

- 6 years, 3 months ago

That's what I thought too... xD

- 6 years, 3 months ago

mine is on 28 .I and brilliant are "twins".Yay/

- 6 years, 3 months ago

Nope ... you are 14 years older than it. xD

- 6 years, 3 months ago

It was just for fun.

- 6 years, 3 months ago

Anyway , we are born in october :)

- 6 years, 3 months ago

Haaha i was born in may but the date is same.

- 6 years, 3 months ago

Oops! I didn't know that! Lolzzz

- 6 years, 3 months ago

Wow ! My B'day is on the 2nd ! Haha , I am older than B'ant by 26 days 12 years :P

- 6 years, 3 months ago

Sure, this time we all together will rest only after getting the reply.

@Calvin Lin sir, Brilliant wants the answer !

- 6 years, 4 months ago

Brilliant has really been like a boon to me. Until I started solving problems on Brilliant, I used to be weakest in Maths(during 11th). Gradually it has become my strongest subject and now I look forward to solving Maths. I would like to thank the Brilliant community for posting such nice questions. It has been a truly wonderful experience here.

Which age group contributes the maximum part of the users on Brilliant ?

Maybe 14-19

- 6 years, 4 months ago

You might want to add some more ages as well . $24 , 30 , 49$

Just enter Sandeep sir's ,Calvin sir's and Brian sir's names in the search box and check out the number of questions that they have posted !

- 6 years, 4 months ago

The question was "Which age group contributes the maximum part of users on Brilliant", not questions.

- 6 years, 4 months ago

Oops! You got me . Thanks for the catch. Btw , what's your opinion on this question ?

- 6 years, 4 months ago

Depends on how large a group you want. Otherwise, you could just say $(0 - 200)$ age group. Though 13-18 sounds correct.

- 6 years, 4 months ago

Thought so too . I started with Skeptical Patriot . I liked the plot , so i have saved it for reading after JEE mains .

- 6 years, 4 months ago

For Q4 I think India should be the answer.

- 6 years, 4 months ago

Yes it looks like India only.!
