Even with that level of time compression, the movement is still almost imperceptible. Be sure to click on the link and check out the video.
- Why is there a ketchup bottle near the end of this slide deck? I sure hope the author isn't making that dreadful comparison of thixotropy and/or shear-thinning in ketchup to the crude oil he was studying.

- It is widely known that the recently-deceased, former Prime Minister of England, Maggie Thatcher was a chemist by training. Nicknamed "The Iron Lady", I would have thought she was an inorganic chemist, but I found out yesterday that she was in fact a polymer chemist who worked on developing "an adhesive to stick PVC to wood and metal". She only "stuck" (GRIN) to the task for a few years before going to law school and then entering politics.
