"For a physicist, it is indeed a great joy to learn how we can use beautiful mathematics to understand the real world." In Stephen Weinberg's "Without God" (9/25/08, The New York Review of Books)
TED Video which speculates on the next 5000 days of the web. Infers connections between web and brain strucutre interconnectivity.
Also a nice fluid dynamics video of experiments being done on the interntational space station in micro gravity.
Stumbled upon a video clip demonstrating 'structured illumunation' microscopy which gives a 2x increase in optical resolving power past the usual diffraction limited 200nm feature size dictated by 1/2 wavelength of the smallest visible light ~400nm. It uses compuational image processing of moire patterns created by illuminating the sample with 2 or more gratings at various offsets to each other.
How is it posssible to rationally design and make materials that have highly organized micro-structure?
Periodic and pseudo random structure occurs in many naturally formed materials, but not necessarily at the desired scale, or with a specific repeated unit or material. Non-periodic but deterministic structure is less common in non-living physical systems, but is the rule for living systems.

Interesting video on a parasitic wasp life cycle which utilizes a spider. And another parasitic wasp that utilizes a caterpillar.
