Fundamentals of Model Theory  - Model Theory is the part of mathematics which shows how to apply logic to the study of structures in pure mathematics. On the one hand it is the ultimate abstraction; on the other, it has immediate applications to every-day mathematics. The fundamental tenet of Model Theory is that mathematical truth, like all truth, is relative. A statement may be true or false, depending on how and where it is interpreted. 

Fundamentals of Optimization - This is an introductory course in theory and methods for finite-dimensional continuous optimization. A mathematical optimization problem is one in which a given function is either minimized or maximized relative to some set or range of choices available in a given situation.

The Origin of Mass and the Feebleness of Gravity  - .Lecture by Frank Wilczek. This lecture proves the point, as Wilczek goes after one of the deepest questions in science: What is the origin of mass? Rewriting Einstein’s famous equation as m=E / c2 dramatizes that energy is the source of mass; energetic but massless quarks and gluons, Wilczek argues, give rise to mass by finding quasi-stable equilibrium states, better know as protons and neutrons. 

Bose-Einstein Condensates: The Coldest Matter in the Universe - Video LectureWhat happens when a gas is cooled to absolute zero? A new door to the quantum world opens up because all the atoms start "marching in lockstep", forming one giant matter wave . the Bose-Einstein condensate. This was predicted by Einstein in 1925, but only realized in 1995 in laboratories at JILA in Boulder and at MIT. Since then, many properties of this mysterious form of matter have been revealed, including matter wave amplification and quantized vortices. Bose condensates have been used to realize a basic atom laser, an intense source of coherent matter waves
