Only a black hole — which is made of pure gravitational energy and gets its mass through Einstein's famous equation E = mc2 — can pack so much mass into so little space, says Bruce Allen, a LIGO member at the Max Planck Institute for Gravitational Physics in Hanover, Germany. (sciencemag.org)
Bragg's Law is one of the most famous equations in science and has played a vital role in many subsequent discoveries, from the development of antibiotics to the uncovering of the double helix in DNA. (education-today.co.uk)
In his fourth missive, Einstein showed that energy and matter were different faces of the same thing, their relationship described by the most famous equation in all of physics: energy equals mass multiplied by the speed of light squared, E = mc2. (discovermagazine.com)
