A collection of mathematical fascinations, not strictly limited to the subject itself but also people's interactions and interpretations. My curiosity for the subject is infinite, but I try to stay away from the sciences. The thrill lies in the purity, not the application.

lifeiscooool asked: sooo i kind of have a problem(not really a problem ) and i need some help please give it a try !! so 4 girls have performed a number of songs each song is performed by 3 girls. A has performed the least number of songs which is 4. d has performed the most ; 8 songs . How many songs have these girls performed all together ?
3 * (number of songs) = Total # of performances. Note that this means the # of performances is a multiple of 3.
4 < B, C < 8 ====> B, C = 5,6, or 7
We need A+B+C+D to be a multiple of 3. Since A+B = 12 = multiple of 3, we need B+C to also be a multiple of 3. The only ways for this to happen with the given choices are 6+6 or 5+7, both of which equal 12. 12 + 12 = 24 total performances = 8 songs.
yourssadiestar asked: Hey my name is sadie (yourssadiestar) can you tell me the best 3x3 is to buy that is not lots of money please!
Hmmm. I don’t speedsolve, so I’m probably not the best person to ask. I have a Dayan Guhong Version 2 [$16], which is really great for me. I’ve heard other people say the Dayan Zanchi [$18] is really good, too. A good place to order is either HKNowStore [best selection, average prices] or E3CubeStore [best prices, small selection].
To answer your other question, I’m not really interested in doing a collection video. Sorry. I can definitely go into more details on individual puzzles if you’d like. Or if you’re into collections and unboxings, I can point you to several good YouTube channels. Let me know.
So, the euler spiral! It’s the big one at the top. It’s traced out by the parametric equations written under it.
I thought something interesting would happen if I replaced the cosine and the sine with the derivatives of the parameterizations of various other curves, and then this happened.
So basically Euler Spirals on acid. Wicked.
