The world’s top particle physics lab said Friday it had measured the decay time of a particle known as a Bs (B sub s) meson into two other fundamental particles called muons, which are much heavier than but similar to electrons.

The Top Quark, also known as the t quark (symbol: t) or truth quark, is an elementary particle and a fundamental constituent of matter. Like all quarks, the top quark is an elementary fermion with spin-1⁄2, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. It has an electric charge of +2⁄3 e,[2] and is the most massive of all observed elementary particles.

Who would not need this backpack? This has taken "geek" to a new level. I reworked the image referenced below and printed on Cotton-linen canvas (Spoonflower). A true sp.
