In mathematics, specifically in the field of numerical analysis, Kummer's transformation of series is a method used to accelerate the convergence of an infinite series. The method was first suggested by Ernst Kummer in 1837. (Wikipedia).
In this video, I define a cool operation called the symmetrization, which turns any matrix into a symmetric matrix. Along the way, I also explain how to show that an (abstract) linear transformation is one-to-one and onto. Finally, I show how to decompose and matrix in a nice way, sort of

Suppose you have two bases of the same space and the matrix of a linear transformation with respect to one bases. In this video, I show how to find the matrix of the same transformation with respect to the other basis, without ever having to figure out what the linear transformation does!

See the new Star Wars-like display that could revolutionize virtual reality
Forget light sabers. Researchers on Earth have invented something far flashier: a Star Wars–like 3D display that simultaneously projects video, sound, and even the sensation of touch. The new displays can’t create holograms as complex as Princess Leia’s famous distress call. But with furth

What is the Lorentz Transformation?
What is the Lorentz Transformation? It is a tool we use to relate the different experiences of different observers in special relativity. It is also one of the defining features of special relativity and what differentiates it from Galilean relativity. In this video, we will derive the Lor

Gregory Sankaran: Moduli of deformation generalised Kummer varieties
Two of the four known types of compact hyperkahler manifolds arise from K3 surfaces and two from abelian surfaces. The moduli spaces of polarised varieties of the K3 types have been extensively studied, but less attention has been paid to the abelian types. I shall describe some work in pr

We introduce the definition of the Log-Kummer Correspondence. While there is not direct definition we can point to this is used throughout IUT3 and is what gives rise to Ind3. This is actually quite tricky. For example, a Log-Kummer correspondence doesn't exist for tensor packets but is i
