“Not Linear? Not a Problem!” at 12:30 PM on 10/22 via Zoom Colloquium Talk by Professor Sanjay Dharmavaram Abstract: Ever wonder why  mathematics classes focus so much on linear problems? In Calculus we learn about linear approximations. In Differential Equations, after classifying differential equations as linear and nonlinear, we mostly focus on linear problems. Linear Algebra focuses exclusively on systems of linear equations. There are two reasons for this: 1) nonlinear problems are hard!! Unlike linear equations, there is no unified theory that works for all nonlinear equations. 2) linear approximations are often a good starting point to study nonlinear problems. In this talk, we will make a foray into the marvelous […]

“Not a Normal Math Talk” at 12:30 on 10/1 via Zoom Student Colloquium Talk by Professor Michael Reeks. Abstract: Anyone who has ever shoved a pair of headphones in their pocket knows about the following general principle of the universe:”Any flexible strand will tie itself in knots as soon as it’s given the opportunity.” As such, knots are ubiquitous in nature and art: – DNA strands, so often pictured as tidy helices, actually spend most of their time hopelessly knotted;– the way in which proteins interact and function depends heavily on the way they are folded, or knotted, together;– and some of the oldest known art is based on complex […]
