About Us
One web page for every book ever published. It's a lofty but achievable goal. To build Open Library, we need hundreds of millions of book records, a wiki interface, and lots of people who are willing to contribute their time and effort to building the site. To date, we have gathered over 20 million records from a variety of large catalogs as well as single contributions, with more on the way. Open Library is an open project: the software is open, the data are open, the documentation is open, and we welcome your contribution. Open Library is a project of the non-profit Internet Archive, and has been funded in part by a grant from the California State Library and the Kahle/Austin Foundation.

5 Really Weird Things About Water
Water, good ol' H2O, seems like a pretty simple substance to you and me. But in reality, water - the foundation of life and most common of liquid - is really weird and scientists actually don't completely understand how water works. Here are 5 really weird things about water: 1. Hot Water Freezes Faster Than Cold Water Take two pails of water; fill one with hot water and the other one with cold water, and put them in the freezer. In 1963, a Tanzanian high-school student named Erasto B. Thankfully, Mpemba didn't back down - he convinced a physics professor to conduct an experiment which eventually confirmed his observations: in certain conditions, hot water indeed freezes before cold water*. Actually, Mpemba was in good company. But how do scientists explain this strange phenomenon? 2. Everybody knows that when you cool water to 0 °C (32 °F) it forms ice ... except that in some cases it doesn't! Note: Similarly, superheated water remains liquid even when heated past its boiling point. 3. 4.

My subversive attempts to do something useful. The Rotary Piston Array Machine -- Air-Sea Temperature Difference Engine -- Solarthermal Power Generator The Rotary Stirling Engine The Wave Pump Heat Engine With No Compressor Portable Tent Platform The rotary piston array (RPA) is the possibly most compact and most elegant machine to transform the volumetric change of gas into shaft work and vice versa. It can be used as pneumatic motor, steam engine, gas compressor, vacuum pump and the like, but also as part of new heat or combustion engines which – like the Stirling engine – open new ways to harvest renewable energy. Other possible uses are refrigeration and air-conditioning. The idea has been overlooked for at least 110 years, as some old patents indicate, and it seems to have been reinvented several times (e.g. The machine comprises an array of equally shaped twisted rotors with parallel axes.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. Its content reflects the fact that my interest lies in history and philosophy of science and that I teach in a Department of History and Philosophy of Science. This text owes a lot to many. i i i
