@abakcus The Principia was such an important, influential book that I wrote a book about it!

In 1687, Newton published Principia Mathematica. Motion, gravity, calculus—written in ink. Here’s the original copy, annotated by Newton himself: cudl.lib.cam.ac.uk/view/PR-ADV-B-…

@PlantRobinson That was quite the thought provoker. Thanks for sharing! Oh and stuff like this, and your beautiful selfies, are why many of us would be noticeably sad if you went away. 🙏🥰

In 1697, Jean Bernoulli gave mathematicians 6 months to solve the brachistochrone problem. Isaac Newton received the challenge on January 29, and solved it the same night before going to bed.

@aliciaandrz It has always intrigued me that our brains, the so-called pinnacle of evolution, contains so much self-destructive programming. 🤷‍♂️😂

@sadgirlcassi In general I’m not a fan of the death penalty because of general government incompetence, but in this clown’s case I’m willing to make an exception 😂🖕

KILL THE ABUSERS
Brian Allen@allenanalysis

🚨 UPDATE: $1.25 MILLION bond for “Chud the Builder.” His real name is Dalton Eatherly. He’s the livestreamer who built a following yelling racial slurs at strangers on camera. Yesterday he shot a disabled Black veteran outside a Tennessee courthouse. The veteran; last name “Fox,” took bullets in the stomach and the shoulder. His wife is now begging strangers online to help pay the hospital bills. The same guy was out on a $5,000 bond from four days earlier. The judge said that’s part of why the bond is so high this time. $1.25 million. Think about this for a second. A man served this country. Came home with a disability. Walked past a courthouse on a Wednesday afternoon. And got shot; because some guy with a phone makes money being cruel to people. That’s the country right now. Cruelty pays. Slurs are a paycheck. And a veteran is in a hospital bed. What kind of country lets a man build a business out of hurting people?

@mathemetica At least mention that your derivation is for the special circular orbit case (ε=0) but Kepler’s 3rd Law applies to all elliptical orbits (ε≠0).

On this day in 1618, Johannes Kepler confirmed his Third Law of Planetary Motion: The square of a planet’s orbital period (T²) is proportional to the cube of the semi-major axis of its orbit (a³). The modern Newtonian derivation: > Equating gravitational force to centripetal force > Substituting orbital velocity v = 2πr/T > Resulting in T² / r³ = 4π² / (GM) The log-log graph confirms the relationship holds for planets in our Solar System. A foundational law that bridged empirical observation with gravitational physics.
