Rick's General Physics Menu Page

The random collection of topics below share only the common feature that I find them intriguing. Much of the material is "well known", or at least in the literature somewhere. But bits are original (most probably the bits that are wrong).

As of 21/4/2012 the first item in the list below is my 'work in progress' under the working title "Theoretical Physics: Some Choice Cuts". This link takes you to a page where you can read or download various draft essays in theoretical physics (48 available at present, with a total of 58 planned).

The second item in the list below, the 'Introduction to Quantum Mechanics', is a separate tutorial in its own right, and the link starts with an introductory page.

If you spot any errors, or have any related questions or clarifications, please do let me know.

New comprehensive maps of Greenland and Antarctica show extent of glacier thinning [Credit: ICESat,NASA]. Reporting in September 2009 in Nature, researchers from British Antarctic Survey and the University of Bristol describe how analysis of millions of NASA satellite measurements from both of these vast ice sheets shows that the most profound ice loss is a result of glaciers speeding up where they flow into the sea. The authors conclude that this 'dynamic thinning' of glaciers now reaches all latitudes in Greenland, has intensified on key Antarctic coastlines, is penetrating far into the ice sheets' interior and is spreading as ice shelves thin by ocean-driven melt. Ice shelf collapse has triggered particularly strong thinning that has endured for decades.
