Filing papers

Further to my earlier post, I would be interested to know how people file papers and other useful information. By category? By project? By author? Or all electronically to enable keyword searching?

Keeping notes

When I began my research career, I used loose leaf paper to make notes about ideas, inspirations, detailed calculations, experimental data, and texts I was studying from. I then gathered these into suspended folders for different projects. This way I could maintain my notes very easily - when an idea was superseded or when several [...]

Mathematics as art

The American Mathematical Society has a nice little section on Mathematical Imagery.

The links at the foot of the page are also very good. In my opinion, the best is to The Institute For Figuring.

Back of the envelope

Confronted with a novel problem at work or at home, the first thing that anyone from several generations of physicists, engineers, and applied mathematicians would do is reach for the nearest scrap of paper. On this, she will sketch a very rough model, an approximate set of equations, which describes the situation. She will then [...]

Extraterrestrial hurricanes, implications for Religious

The first hurricane-like system on another planet has been imaged by the Cassini probe. With a well-defined eye and eye-wall, this monstrous 8,000km-wide storm spins near Saturn’s South Pole with wind speeds of 550kph.

A mythological history of science

The philosopher Robert P Crease, writing in this month’s Physics World magazine, brings to light an interesting phenomenon amongst professional scientists: the mythologization of scientific history. The apple that fell on Newton’s head, Galileo dropping balls from the Leaning Tower of Pisa: these and others reveal something both interesting, and perhaps slightly dangerous, in the [...]
