#mathober day 27: Indefinite Quadratic
Here are some quadratic functions that are *definitely not* indefinite – I found it more interesting to draw many of those!
Can you guess from the drawing what being indefinite means in this case?
#mathober day 28: Conic Double Point
This is the Barth Sextic, a sexy surface with no less than 65 conic double points!
#mathober day 29: Two Triangle Theorem
This theorem states that if you build a kite out of two triangles, you will be pretty happy!
#mathober day 30: Spheroidal Wave Function
This is based on a plot of R_{10, n}^(1)'(10, ξ) which I found in a paper by Adelman, Gumerov and Duraiswami from 2014 – their motivation was to compute acoustic scattering!
#mathober day 31: Existential Closure
There exists an 𝑥 so that
a) 𝑥 is the author of this toot and
b) 𝑥 had a lot of fun with #mathober!
This was a great format to peek into many different branches of mathematics, and also to experiment with digital drawing and #krita!
Thanks to everyone who participated! =)
@blinry You missed the opportunity to have a current events reference. Anything based on four this week ...
@blinry beautiful!!
@blinry beautiful!!
@blinry Yes! I have really enjoyed sharing in this. Your collection is wonderful. Thank you.
