Lecture    Abstract

In this talk, I will briefly discuss the   importance of mathematics in electrical engineering. From my experience in   USA over the past decades, I see that the most significant change in human   daily life is in communications, such as smart phones, where mathematics   plays an important role. I will briefly introduce some of the key components   of math in communications: some elementary math and some more advanced math,   such as, finite fields and orthogonal designs (or compositions of quadratic   forms) etc. I will finally briefly show some of our recent results on   orthogonal designs.
