Nitrogen (N) has 7 electrons.

Again, this is a famous 10-vertex graph in mathematics called the Petersen Graph.

the element Nitrogen, which makes up 78% of the Earth's atmosphere, has 7 electrons (1s2 2s2 2p3).

the Petersen graph, a very famous graph in graph theory, is one of my favorite ways to represent the number 10! (it has 10 vertices.)

first of all, thank you for all the kind words regarding my script and for your amazing voiceovers! thought i'd give it a shot myself. i think this character would be one who'd enunciate his/her every word very clearly and slowly, so as to convey the weight of each one.

a more difficult proof than the last... but this is a famous identity! some people inexplicably use it as proof that God exists (?___?).

here is the sun used; when i made the original back in 2010, i had a much better editing program, but am now cursed with the inability to make HQ gifs -- if anyone wants to make the logo better by making the sun higher quality, please do!

if anyone needs clarification on the geometric series part, let me know! also, if people are interested, i can do more of these math facts about 1 :o) 1 is a pretty badass number, and (like 0, my fav number of all), is essential to mathematics.
