Complex surfaces | Algebraic surfaces
In algebraic geometry, a Togliatti surface is a nodal surface of degree five with 31 nodes. The first examples were constructed by Eugenio G. Togliatti. Arnaud Beauville proved that 31 is the maximum possible number of nodes for a surface of this degree, showing this example to be optimal. (Wikipedia).
Surface Features of Asteroid Toutatis Revealed by Radar
With optical telescopes, it's difficult to make out the surface features of asteroid Toutatis. Radar gives us a different picture. On Dec. 12 and 13, 2012, scientists pointed NASA's Goldstone Solar System Radar precisely on the asteroid while it was over four million miles/6.9 million kil

Surface of the Sun as You've Never Seen it
Our sun is an incredible fusion engine. From the surface of earth, we see it as a mere ball of light, but through amazing high-res imaging capabilities, we can observe real solar activities thanks to NASA's Solar Dynamics Observatory.

Complex surfaces 1: Introduction
This talk is part of a series giving an informal survey of complex algebraic surfaces. We give an overview of the Enriques-Kodaira classification, with examples of most of the different types of surfaces. We conclude by giving an example of a non-algebraic surface: the Hopf surface. Furth

A smaller, faster, cheaper route to fusion energy
Fusion has the potential to be the perfect energy source—safe, clean, and limitless—but scientists are struggling to make it work. Now a change of shape may turn the mainstream reactor design, known as a tokamak, into something simpler, faster, and cheaper. Find out more: http://scim.ag/
