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 English teacher was like, "Ok, we have a visitor today," and this man just walked in to our class. He had a name tag with the words "Visitor Calvin" on it. Our English teacher said, "This guy is a math genius. He works in San Francisco." We were interested to find out more about him, so he told us where he studied, which seemed vaguely familiar to me as I had been to his profile page before. Then, he told us, "I came back to Singapore to see my teachers. I will also be going to another school later, where I went for junior college. Also, I work at Brilliant.org". Immediately, those in my class who were active users of Brilliant couldn't believe their ears, and I asked, "Are you Calvin Lin, the Math Challenge Master?" Then, he said yes, and we asked him a few more questions. We wanted to take a photo with him but we had 51 English questions to do so we bade him farewell. After speaking to our teacher for a few more minutes, he left.

By the way, he doesn't really look like his profile picture. He wears black spectacles. Also, we asked him to say out the square root of 2 truncated to 100 digits but he didn't answer. He was like, "What..." XD

Hi Charlton (whoever you might be)
I would say that I won't really care if you don't believe me. I posted this because I wanted to share my experience with others. You can even ask my teacher (According to you, you said that you knew me well, so you should know my classmates and teachers). You can even ask Calvin yourself.
