Is All About Math

We are dedicated to provide short instructional videos on Mathematics. In these video lectures we handle multiple areas of mathematics. These videos will be useful for teachers and students at many levels.

There is also a companion blog site and there we present topics of interest at blog.isallaboutmath.com

More in the near future. Stay tuned!

Proof
Mathematician Bernhard Riemann explains the importance of proofs in mathematics. He proves a theorem on stereographic projection.

Fibration continued
The mathematician Heinz Hopf describes his "fibration". Using complex numbers he builds beautiful arrangements of circles in space.

The fourth dimension continued
Mathematician Ludwig Schläfli talks to us about objects in the fourth dimension and shows us a procession of regular polyhedra in dimension 4, strange objects with 24, 120 and even 600 faces!
