Comment: mathematically equivalent ? (Score 4, Insightful) 89 89

Now, a physicist has shown that on a large scale, the tunneling motion of atoms through the lattice is mathematically equivalent to the motion of atoms in a quantum field in a flat spacetime.

mathematically equivalent ?

So they haven't created curved spacetime in a Quantum Optics Lab. They have done something that is a model of how they think curved space time would behave.

And editor Soulskill made some useful edits to my submission as well, adding links to the individual games and changing my "(+3 -0 =7)" results to a more understandable (to non chess players) "(3 wins, 0 losses, 7 draws)"

+ - 22 year old Norwegian Magnus Carlsen is the new World Chess Champion

Carlsen became the youngest ever World No. 1 in 2010 but withdrew from the 2012 championship cycle and so has only now been able to add the World Champion title to his No 1 ranking.

He won three games and lost none, his first two victories came when he was able to convert small advantages in the end game into wins. The third (in game 9) came after an Anand blunder.
