Complex surfaces | Algebraic surfaces
In mathematics, a Beauville surface is one of the surfaces of general type introduced by Arnaud Beauville . They are examples of "fake quadrics", with the same Betti numbers as quadric surfaces. (Wikipedia).
Teach Astronomy - Landscape of Mars
http://www.teachastronomy.com/ Mars has richly varied surface features. There are rocky planes, gullies, riverbeds, smooth sea bed floors, sand dunes. There are dust storms that encompass large fractions of the planet's surface during certain seasons. There are huge gullies and crevasse

Alessandra Sarti : Automorphisms of Hyperkähler manifolds - Part 2
Abstract: In the 80's Beauville generalized several foundational results of Nikulin on automorphism groups of K3 surfaces to hyperkähler manifolds. Since then the study of automorphism groups of hyperkähler manifolds and in particular of hyperkähler fourfolds got very much attention. I wil

Parametric Surfaces In this video, I give 5 examples of how to parametrize surfaces. This is similar to parametrizing a curve, except that this time you need two variables. This is an important tool for surface integrals, which is a way of integrating a function on a surface. Parametriza
