Walkabout the Galaxy
black holes; ancient craters on Earth; Ham Sandwich Theorem
Astrophysics and Astronomy | Physics
The astroquarks debate the relative merits of hair and baldness in the grand context of black holes and the ultimate question of the nature of information in the universe. Not bad for a cheeky title! We also take a look at some ancient craters on the Earth, and the Ham Sandwich Theorem, among others.
The Planck Constant
Whether you want to know the energy of a photon, or the constant increment of angular momentum, you can use the Planck Constant. This versatile quantity has been helping us discretize the universe for 120 years. Doing away with the notion of continuous variables and atoms and light, but that's not all. If you're beating your head against the wall trying to get your measurements of positional velocity exactly correct, let the Planck Constant save you from pointless grief and frustrations by showing you that that is just not possible with our optional Heisenberg Principle for a nominal additional cost. With units of action, you won't want to be caught without the Planck Constant, whether you're spinning, vibrating, or making any kind of venture into the quantum realm. The Planck Constant, don't leave home without it (American Express).
