Who is the "Challenge Master?"

Who is the "Challenge Master?" I've been wondering if it was just a bot but it doesn't seem to be so. Who is it?

#ChallengeMaster

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.

He is our beloved Calvin Lin!

Oh. Makes sense.

Just curious , are you really 89 years old?

Nihar Mahajan - 5 years, 7 months ago

@Nihar Mahajan – Nihar, which topic is given to you to moderate ?

A Former Brilliant Member - 5 years, 7 months ago

@Nihar Mahajan – Nah, just a private person.

Xiaoying Qin - 5 years, 7 months ago

And others too.

Calvin Lin Staff - 5 years, 7 months ago

Wait , Is there someone other than you too? If so , please tell , I am curious :P

There were originally three challenge masters : Calvin Lin and Arron Kau for mathematics and David Mattingly for physics.

Not sure if it's changed now or not. Haven't seen David post anything since quite a while, so I think he might have left Brilliant and new challenge masters might have been added in. Arron is still active but not as much as Calvin. You might as well just say that Calvin is the Challenge Master for mathematics since he's almost the only staff member who's almost always active on the site.
