Research-Life Stories – Yuri Gurevich

Yuri Gurevich shares an anecdote about beginnings which he refers to as "Research-Life Prehistory" ------------ Mathematics is the last refuge of platonism. In what sense, mathematical objects – from real numbers to Banach spaces – exist? Where are they to be found, detected by experimental means? Mathematical platonism comes very naturally to working mathematicians. When you … Continue reading Research-Life Stories – Yuri Gurevich

From Discrepancy to Privacy, and back Part 2: Approximating Hereditary Discrepancy

In a previous blog post, we saw how ideas from differential privacy can be used to prove a lower bound on the hereditary discrepancy for the Erdös Discrepancy problem. This lower bound happened to be nearly tight. It turns out that this tightness is no accident. The connection between hereditary discrepancy and privacy is in … Continue reading From Discrepancy to Privacy, and back Part 2: Approximating Hereditary Discrepancy

Alt Equals

I recently discovered that some colleagues are unaware of the math typesetting capabilities in PowerPoint, and so as a responsible Microsoft employee I thought it my duty to inform the public of these potentially time-saving and slides-beautifying features. This is also for my own benefit, as I seem to always forget where to find the … Continue reading Alt Equals
