15 is for… erm… T-violation. Why does time prefer one direction over the other? We don’t know the full answer, but we do have some hints from the quark sector.

14 is for 14TeV, what we had planned for the LHC. So this video is all about how we glimpsed into the distant and not so distant future of particle physics. We need to keep looking ahead, the LHC is not the end of the journey!
Some links from the CERN public page about the accelerator complex and history:

13 is for… well 13 squared is 169, which is almost 173.5, which is for the mass of the top quark in GeV. So let’s talk about the top quark!
The 12 days of Higgsmas! I can’t sing, but I made this anyway. Enjoy!

11 rhymes with 1927, so let’s talk about the fifth Solvay Conference!
See some of video footage of the conference itself: http://www.youtube.com/watch?v=8GZdZUouzBY
Although the Heisenberg matrix method and Schrodinger wave mechanics had already been reconciled in 1926, and most physicists had come to a consensus shortly after the Solvay Conference, Bohr and Einstein continued to disagree. They discussed their disagreements extensively in the famous Einstein-Bohr debates, and this culminated in the famous EPR paradox in 1935. The resolution of the paradox would not come until long after Einstein had died. You can read Einstein’s infamous paper here: http://prola.aps.org/abstract/PR/v47/i10/p777_1
10 is for the missing 10th particle. It’s no longer missing! A single event completed our view of the light spin-3/2 baryons.
See the movie Decay: http://www.decayfilm.com/

Apologies for the lateness, I’m playing catch-up following a busy week and many technical issues!
9 is for the 9 elements of the neutrino mixing matrix. Why do they mix? What does it tell us? Does this give us even more matter-antimatter asymmetry?
8 is for gluons! They’re strong, they’re coloured, and you can never catch one all by itself!
Why is spin called spin? After all, nothing is spinning! To find out we need to go back about 100 years…
“Who ordered that?!” Those infamous words, uttered by Rabi, were the first sign that there was more to the universe than just protons, neutrons and electrons. Meet the muon!
