In Light Of A Four Day Ceasefire In Gaza Being Agreed Upon, I Am Once Again Asking You All Not To Lose

Saw this tweet and had to collect Ryan Gosling’s best PR quotes for Barbie

i cannot explain it but these all have the same vibes

Dear god. please make all superyachts explode tomorrow. amen.

Rant 1: Gravity and Predicting the Future (Physics,History)

Okay I know a lot of us here don't like physics a lot, and I can agree when it comes to weird formulae and counterintuitive theorems, but bear with me for a second here, it gets intersting

Newton's universal law of gravitation. Any science student has seen it at some point in their study lives and love it or hate it, it represents what's keeping the universe from spinning out of order (at least at a larger scale).

As students who are made to tediously calculate the force acting between two arbitrary planets we might not appreciate this simple equation too much, but it marks an important turning point in the history of the human race: where we finally managed to gain a true scientific and mathematical insight into the movements on our planet and those that occured in the infinite heavens above.

A: Halley's Comet

The ubiquitous equation appeared in the first volume of Sir Isaac Newton's Principia which was presented to the Royal Society. Although the Principia managed to explain a lot of observations, some of which remain remarkably relevant today, Newton's research on comets on comets was incomplete. This is where Edmund Halley, Newton's editor, publisher and friend steps in.

Using Newton's Laws of Gravitation and Motion for the mathematical aspect, Halley analysed 24 cometary observations and found a pattern emerging in the path of one that had been observed in 1682. Based on historical records the same comet had zoomed past earth in 1607 and 1531. If his work and Newton's theorems were correct, he predicted, in 1705, that the comet should return in 1758.

Lo and behold! A Christmas miracle! On 25th December, 1758, Johann Palitzsch, a German amateur astronomer, witnessed Halley's comet. Halley himself had died in 1742 and could not witness the momentous occasion, but the celestial body's return cemented Newton's work in the scientific community and remained unshaken for over two centuries until Einstein came up with General Relativity.

B: Newton can't be wrong, it must be an entire other planet!

With better telescope systems, astronomers were able to peer farther into space than before, the discovery and observation of Uranus, however raised controversy, since its orbit did not comply with the predictions from Newton's laws.

Many were ready to believe that the giant had fallen: Newton's age old theory had been disproven and it was time to move on, but a few scientists like John Couch Addams proposed an unseen planet whose gravitation caused anomalies Uranus' orbit.

About 4 years after Couch's proposal, in 1845, Urbain Le Verrier, a French astronomer and mathematician started the tedious work of calculating this invisible planet's location, purely from the motion of Uranus and mechanics. After many months of complex calculation, he presented his solution to the French academy on 31st August 1846.

On 23rd September in the same year Neptune was observed with a telescope for the first time and its location was within 1° of Le Verrier's prediction. Which is an utterly wild achievement, considering that it was the first time that a human had discovered a planet at the tip of their pen.

C: But it's outdated!

Yea yea Einstein's Theory of General Relativity is a much better explanation of gravitational phenomena, but even today, Newton's approach provides a REALLY good approximation of how it works. The only cases where Newton's theorems don't work are those with extreme gravity: such as black holes or between the Sun and Mercury.

So the next time when you're solving a question on gravity, maybe you'll appreciate the sheer power of the human mind and this tiny equation: that lead to our first great leaps in astronomy and still power things like air travel and architecture. Or you'll appreciate it thinking, "hey, at least I don't have to sit around for months trying to find something that I haven't even seen". Either way, you'll hopefully like this part of physics just a tiny bit more :)

This just seems the right time to share that my grandmother once told the family her second cousin had "erotic autism" instead of an aortic aneurysm

i think all quiet on the western front and the lord of the rings are in direct conversation with each other, as in theyre the retelling of the same war with one saying here’s what happened, we all died, and it did not matter at all and another going hush little boy, of course we won, of course your friends came back

"I bet it doesn't hurt that bad, I don't have time for this shit."
