Aluminium was once the most expensive metal on Earth - costlier than gold
Not because it was rare (it's the most abundant metal in Earth's crust, ~8% of it), but because extracting it from its ore was incredibly difficult
The HallβHΓ©roult process, invented in 1886 by two 22-year-olds, changed that β and with it, aluminium went from a luxury metal to something you wrap your sandwich in.

Niels Bohr was a Danish physicist who made groundbreaking contributions to the understanding of atomic structure and quantum theory. He is best known for developing the Bohr model of the atom, which explained how electrons move around the nucleus in fixed energy levels. His work played a major role in the development of modern physics and helped scientists better understand the behavior of atoms and radiation.

This educational diagram illustrates the fundamental principles of Bohrβs Model of the Atom. It explains how electrons occupy specific orbits, the release of energy as light when an electron drops to a lower orbit, and how physical properties like orbital radius and electron speed change relative to the atom's energy levels.

Itβs from the Bacillus Calmette-GuΓ©rin (BCG) tuberculosis vaccine, commonly given to children in many countries (especially outside the US) via a skin injection.
The vaccine often leaves this distinctive round, slightly raised or dimpled scar with a textured, starburst-like pattern as it heals. Perfectly normal and harmless reminder of an old shot.
