In a feat of modern-day alchemy, atom tinkerers have fooled hydrogen atoms into accepting a helium atom as one of their own. The camouflaged atom behaves chemically like hydrogen, but has four times the mass of normal hydrogen, allowing predictions for how atomic mass affects reaction rates to be put to the test.

Llantrisant and Taff Vale Junction Railway

Interesting article on Wikipedia (quite a lot of which I'm responsible for...especially the map) about the railway line between Pontypridd and Llantrisant as well as the "Barry Railway" branch:

Llantrisant and Taff Vale Junction Railway

Additionally some fantastic pictures of Tonteg Halt and Junction. This was the post 1930 Tonteg Halt station after track rationalisation between Tonteg and Treforest High Level and Llantwit Road, the former Tonteg Halt was further down Maes Mawr road.

Interesting posting about a solution to the 3-SAT problem which might indicate P=NP.

Coelho Gives Away His Books - Newsweek

Confirming the fact that theless restrictions on usage, the more people will willingly pay instead of pirating it.

Same applies to software, hardware, whatever. If you make it difficult for the legitimate user/owner/reader/listener to use then they will use the priated version. Music and Film companies take note.

The Open University...

...remeber those lectures broadcast late at night on the BBC? Here's a comedy version to bring back some memories:



Of course, this might be completely incomprehensible from a historical and humourous perspective to probably most of the universe.

Must admit Huw Laurie's lecture sounds extremely authentic
