But anyway, this is a paraboloid. Remember parabolas from your old algebra class? The general form for a quadratic equation is:
y = ax^2 + bx + c
The real kicker here is the squared x term. Now, imagine things in three dimensions, where some dependent variable z depends on the square of two independent variables, x and y. In other words, it’s like a 3D parabola! In this case, I chose a pretty simple equation:
z = 5 (x^2 + y^2)

“The Platonic Solids project explores how a purely operations-based geometric process can generate complex form. The resulting forms display a novel aesthetic and an astounding complexity that largely defies attempts at reductionism.”

These images, while they appear to be psychedelic art, are actually colorized images of the Mandelbrot set, a mathematical phenomenon. The Mandelbrot set is a pattern of geometric points that repeats within itself (meaning that any image you take of a particular section of the set can be replicated by zooming in or out) and and is infinitely complex; it is what’s known as a fractal. More info, images, and video of the Mandelbrot set can be found here.

Valentina Tereshkova orbited the Earth 48 times during her three day spaceflight in Vostok 6 in 1963. First woman in space!
Svetlana Savitskaya became the second woman in space when she flew the Soyuz T-7 to the Salyut 7 space station in 1984. First woman to perform a spacewalk!
