Cutest mathematician I have ever seen.

Damn, I wish she was my math teacher.

Wait, forget that, I wish she was my girlfriend.

You know you use computers too much when 4096 is the most recognisable number on the page.

[Your2ndPlanB]

I wonder how they discover those numbers.

I cant watch this video cause of the screeching of that bloody pen :(

Maybe she can come over a teach me in person :D

Some other narcissistic numbers!

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634, 8208, 9474, 54748, 92727, 93084, 548834.

The single digits kind of cheat.

The sound of that marker!!!!!!!

@aboylegolcom I think that rather than a simple 'boring versus non-boring' binary state, it would come down to a rating system. Perhaps each number could be given a score from 1 to 10 based on its level of boredom. Then perhaps you could multiply numbers by their scores and find the number for which this product was a minimum. You're quite boring, yourself, you know.

[aboylegolcom]

I wonder what the first positive integer is that has absolutely nothing special about it whatsoever ? A set I define as the 'boring numbers'. What is the first 'boring number' ? Oh, wait, the first boring number would be very special indeed, so it wouldn't be a boring number. OK, so what's the second boring number ? But then again, how boring is boring ? Is it allowed to be even ? Prime ? Divisible by anything ? Hmmm ....

@trstmeimadctr Math is not empirical: it is not based on observation and experience. Please study math more before you try teaching others about it. I really don't want to just discourage you, because I'm sure you can do it. But you haven't done it yet.

[andwhatfire]

@andwhatfire That didn't copy-and-past so well; the last number should be 10^60 instead of 1060.

[trstmeimadctr]

@andwhatfire Yes it does. If you have a reason why you think what you think say it, if not then stop being a troll. You cannot troll with math. It is empirical.
