/sci/ - Science & Math

You have traveled back in time and need to explain quantum mechanics to Isaac Newton.

What do you say to him?

attempting to read the principia mathematica.

Isaac Newton once asked one of the most important questions of all and not one human being on Earth has yet to be able to solve it and explain how they solved it... Give it a try, /sci/?

A 0.105 kg hockey puck moving at 24 m/s is caught and held by a 75 kg goalie at rest. With what speed does the goalie slide on the ice?

None of those guys would have achieved anything without a Briton.

Step up yo game, niggas.

Who is the greatest scientist ever in your opinion?
pic related. my pick.

So OP did you just want /sci/ to choose between being just us or be this guy over here? Seriously?

They do easy examples so you can learn to apply the concepts on simple problems rather than just jumping into something difficult. Once you have done the easy problems you should be able to apply the same concepts to more difficult ones. If you can't take the ideas you've learned and apply them to different examples, then that demonstrates a fundamental inability to learn on your part (retardation) and does not reflect in any way on your teacher. You don't need to see every problem with every degree of difficulty to solve them. Quit trying to memorize how to apply things to specific situations and learn the damn concepts you fucking asian wannabe calculators.

Pic related: His teacher didn't give him any calc examples.

When I plug in the values and apply the quadratic formula to the final line, I don't get the correct solution to <span class="math">v_{1}[/spoiler]. Please tell me how I fucked up.

Whence arises this uniformity in all their outward shapes but from the counsel & contrivance of an Author? . . . Did blind chance know that there was light & what was its refraction & fit the eys of all creatures after the most curious manner to make use of it? These & such like considerations always have & ever will prevail with mankind to believe that there is a being who made all things & has all things in his power & who is therfore to be feared."

"Two people are each pushing a box with the same net force of 100N. One box has a mass of 15kg and the other box has a mass of 30kg. Calculate the acceleration of each box." Can you help?

I have a physics test next week and I dont know how to solve this, can you explain how to do it, thank you!

A 50 N crate is pulled up a 5 m inclined plane by a worker at a constant velocity. If the plane is inclined at an angle of 37 degrees to the horizontal and there exists a constant force of 10 N between the crate and the surface, what is the force applied by the worker?

Isaac Newton was a batshit insane alchemist.

Isaac Newton laid the fundamentals to almost everything we know about physics.

Why can't alchemy and science co-exist?

did the laws of gravity exist before isaac newton discovered them?

Newton was a decidedly odd figure—brilliant beyond measure, but solitary, joyless, prickly to the point of paranoia, famously distracted (upon swinging his feet out of bed in the morning he would reportedly sometimes sit for hours, immobilized by the sudden rush of thoughts to his head), and capable of the most riveting strangeness. He built his own laboratory, the first at Cambridge, but then engaged in the most bizarre experiments. Once he inserted a bodkin—a long needle of the sort used for sewing leather—into his eye socket and rubbed it around “betwixt my eye and the bone as near to [the] backside of my eye as I could” just to see what would happen. What happened, miraculously, was nothing—at least nothing lasting. On another occasion, he stared at the Sun for as long as he could bear, to determine what effect it would have upon his vision. Again he escaped lasting damage, though he had to spend some days in a darkened room before his eyes forgave him.

This is the first time ive herd Newton described like this

yfw I developed most of the calculus concepts that I'm now learning a few years ago to combat other problems I had with high-school-level simplifications in physics.

Weight is just force of gravity. Determine m[spaceship] the plug into Fg=G*m[spaceship]*m[mars]/distance[from the centre of mars]^2

... no Newton...?
