The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them

Vitrification vs. Crystalization

The most basic difference between the glass forming (vitrification) process and the crystallization may be seen in the figure on the left. Vitrification is actually not really a transition , because it does not involve any genuinely singular behaviors, in contrast with crystallization. A very likely implication is that, vitrification should not be due to a critical mode that features long-range correlations. Its dynamics should be essentially local, like what happens to a traffic congestion.

Casimir force between two sheets of graphene
I had thought about this sometime ago but did not come up with the calculations on this problem, basically i did not get time to do that. Now i'm glad that some people have done this. See the following:

Supersolid in history
Supersolid has been a fascinating conception since its inception. However, the experimental aspects are still not conclusive, as reviewed by Thouless in his private note:

This website collects plenty of information of American scientists who have been working in US since 1945 to present. http://www.aip.org/history/acap/
How SSC came into being
Here is an article accounting the history of Solid State Communications. I'm interested in such stuff basically because I'm concerned with how should a practicing scientist regard the platforms fostering their communications.
