The First Image Ever of a Hydrogen Atom's Orbital Structure - What you’re looking at is the first direct observation of an atom’s electron orbital — an atom's actual wave function! To capture the image, researchers utilized a new quantum microscope — an incredible new device that literally allows scientists to gaze into the quantum realm.
Big Bang vs Continuous Creation. Hoyle believed the universe had existed forever. It is expanding because hydrogen atoms are continuously created. This seemed more appealing than the opposing theory that the entire mass of the universe had been created in an instant.
"Joules of the Universe". Diagram depicting all energy levels in the universe, beginning with a single photon, then progressing up to the energy of a hydrogen atom, the energy of an atomic bomb, the yearly output of the sun, and finally the total energy output of the universe. Memorable steps along the way include the energy in a ton of coal, and the energy of a bumblebee traveling at half the speed of light.
