Quantum computers: a time-travelling boost - Sending messages back in time can be remarkably powerful, even if no one ever reads them, says an international research team. Scientists investigated ‘open timelike curves’ (OTCs), which keep all time-travelling particles isolated from the past. They showed that OTCs allow quantum computers to clone quantum states, defy Heisenberg’s uncertainty principle, and efficiently solve previously intractable mathematical problems.
What is the 'God Particle'? -- Higgs Boson Explained | Video - Published on Mar 14, 2013 Physicist John Ellis talks about the subatomic particle that has taken the world by storm. CERN researchers have discovered the particle that gives all other matter its mass with the help of the Large Hadron Collider (LHC) in Europe.
Time Is of the Essence… or Is It? What is time? Isaac Newton described it as absolute, but Einstein proved that time is relative, and, shockingly, that time and space are intricately interwoven. Now recent work in string theory and quantum gravity suggests that space and time may not be fundamental. If this is true, what new picture of reality will emerge?

CKM matrix - In the standard model of particle physics, the Cabibbo–Kobayashi–Maskawa matrix (CKM matrix) is a unitary matrix, which contains information on the transitions in quark flavour during a weak interaction. Technically it describes the differences between quantum states of quarks when they propagate freely and when they take part in the weak interactions. On the picture transitions in quark flavour are illustrated such as the larger squares indicate more likely transitions
