In geometry, Boy's surface is an immersion of the real projective plane in 3-dimensional space found by Werner Boy in 1901. He discovered it on assignment from David Hilbert to prove that the projective plane could not be immersed in 3-space. Boy's surface was first parametrized explicitly by Bernard Morin in 1978. Another parametrization was discovered by Rob Kusner and Robert Bryant. Boy's surface is one of the two possible immersions of the real projective plane which have only a single triple point. Unlike the Roman surface and the cross-cap, it has no other singularities than self-intersections (that is, it has no pinch-points). (Wikipedia).
In the first mini-lecture, we ask the question: what is surface anatomy? We learn how anatomy is the study of the structure of our bodies, including osteology, histology, gross anatomy, imaging, embryology and indeed surface anatomy. As you might imagine, surface anatomy studies the extern

MATH331: Riemann Surfaces - part 1
We define what a Riemann Surface is. We show that PP^1 is a Riemann surface an then interpret our crazy looking conditions from a previous video about "holomorphicity at infinity" as coming from the definition of a Riemann Surface.

Surface integrals are kind of like higher-dimensional line integrals, it's just that instead of integrating over a curve C, we are integrating over a surface S. This can be tricky, but it has lots of applications, so let's learn how to do these things! Script by Howard Whittle Watch the

Calculating the Area of Shapes
We know about all kinds of one-dimensional parameters, like side lengths and what not, but now we want to talk about the two-dimensional area that a shape will occupy. This can be thought of as the amount of surface that a shape covers. In this clip, we go over some of the formulas we can
