But now I am cramped by the space of my paper."
1736: Philosopher and crime-fighter Red Eyes prevents gang of math criminals from kidnapping Leibniz and Newton.
1682: Mathematician John Hadley born. Hadley will lay claim to the invention of the octant, two years after Thomas Godfrey claims the same. Hadley will also develope ways to make precision aspheric and parabolic objective mirrors for reflecting telescopes.
1705: Physicist and mathematician Isaac Newton knighted by Queen Anne at Trinity College.
1958: Chemist and X-ray crystallographer Rosalind Franklin dies. Franklin made contributions to the discovery of the molecular structure of DNA (deoxyribonucleic acid).
1958: Combat physician and alleged time-traveller Asclepius Myrmidon prevents Colonel Zersetzung from detonating the Tybee Bomb.
1958: The United States military announces that the search for hydrogen bomb known as the Tybee Bomb was unsuccessful.
2008: Mathematician Edward Lorenz dies. Lorenz introduced the strange attractor notion, and coined the term butterfly effect.
2018: Phaeton 9 voted Picture of the Day by the citizens of New Minneapolis, Canada.
