Science Friday

The other day I ran across this article while reading SciScoop. I found it worth a read. What’s more, it even explains some ideas in this post.

Quantum Entanglement

The quantum world is full of complementary variables such as position/momentum and wave/particle. The equations describing quantum mechanics are such that precise knowledge of one complementary variable precludes knowledge of the other–regardless of the measurement technique. Even if we could devise a way of accurately measuring position without affecting momentum, the momentum variable would still be imprecise. This is quantum uncertainty as defined by the Copenhagen interpretation, subject to Heisenberg’s Uncertainty Principle.

Large Hadron Collider Goes Online

After today science will have a chance at discovering great unknowns and proving or disproving some of the most fundamental theories in physics. The Large Hadron Collider (LHC) will go online in CERN. Although I have no expertise in this subject matter I will try my hand at a quick summary of the most important points. Follow the jump for a brief introduction and a very nice video explaining it all in rap!
