Mathematicians Of The Day
6th March
On this day in 1689 Edmond Halley first wrote about diving equipment, perhaps prompted by his work on the Thames survey undertaken around that time. Halley proposed a mobile diving bell built on four wheels, and while he did not build that particular bell, he did build another as part of his salvage work on the wreck of the Guynie frigate.

Quotation of the day
From Hans Bethe
No one any longer pays attention to - if I may call it - the spirit of physics, the idea of discovery, the idea of understanding. I think it's difficult to make clear to the non-physicist the beauty of how it fits together, of how you can build a world picture, and the beauty that the laws of physics are immutable.
