That's because of this dirty education system of India. They destroy young minds and turn these interesting subjects into something to be hated upon. Even I had started hating physics and especially chemistry around 10th grade. Before that I kinda understood it but I never had any passion (except for space topics). I was mistaken. I thought the subject was bad but the reality was the teachers were the worst. Now I'm in third year of my ug and have found new passion for maths and especially physics. Chemistry is still far away.

The Great Physicists' Road Trip by Ms. Rachel C. Millison Great physicists and a few of their friends from the past decide to return to Earth for one last road-trip vacation to the coast together. They all appear on Earth on the designated evening. Heisenberg pulls up behind the wheel of a gigantic 1930's car, a huge grin on his face. As they're getting in the car, Hubble looks up and says "What a wonderfully dark sky". "Shouldn't be" responds Olbers. "Always has been" says Hoyle. "No, it hasn't" says Lemaitre. "I knew that!" says an embarrassed Einstein. Once they're all in, Teller says "Hey guys, this trip is going to be The Bomb!". "Yeah, but why do I always have to organize?" asks Oppenheimer. "Where exactly will we end up?" asks Kepler. "That's impossible to predict" says Bohr. "I just can't believe that's true" says Einstein. Heisenberg punches the throttle and the old car roars off. "Say - this thing sure accelerates" says Newton. "I don't know, Isaac. It feels like gravity to me" smirks Einstein. Later that night, as they are speeding down a country road, a police car catches up to them and pulls them over.[1] "Do you know how fast you were going?" the cop asks. [1] "No, but I know exactly where I am" Heisenberg replies. [1] The cop says "You were doing 55 in a 35" [1] Heisenberg throws up his hands and shouts "Great! Now I'm lost!" [1] The cop thinks this is suspicious and orders him to pop open the trunk. He checks it out and says "Do you know you have a dead cat back here?" [1] "We do now, a**hole!" shouts Schrodinger. [1] "I think it's time to split" says Everett. "Scatter!!!" yells a panicked Compton. "Say, officer - how did you manage to spot us on such a dark night?" asks Hubble. "I saw the light from your head lamps" says the cop. "How fast was *it* going?" asks Michelson. "That's simple addition" giggles Galileo. "Not exactly" says Lorentz. "Look here" says Heisenberg, "how do you know I was going that fast?" "I clocked you over a measured distance" says the cop. "How often?" asks Hertz. "I disagree with your measurement, officer" interjects Einstein. "Don't start tonight, Albert" says Bohr, shaking his head. "What Herr Einstein is trying to say" continues Heisenberg, "is that time was running at a different rate for you than for us". "WHAT??? I should have realized that!" exclaims Newton. "I discovered it first" interjects Hooke. "It's true" says Maxwell. "We're all famous scientists and, believe us, Herr Einstein proved it, though it came as no surprise to me". "Must have been a real eureka moment" nods Archimedes. "Extraordinary!" says Galileo. "Extraordinary evidence" asserts Sagan. "Well, it sounds awfully complicated" responds the cop. "Not really. I'll draw you a simple diagram" says Feynman. Totally flummoxed, the cop lets them go with a warning. As he drives away, Doppler cocks his head and listens to the sound of the receding police car. "Gotta love that" he says. "Amen" responds Hubble. Returning to their car, Lord Kelvin remarks "Sure is warm tonight" "Yep - lots of disorder" replies Boltzmann. "In places you'd never expect, Ludwig" adds Hawking. "I was lucky to get away with that" says Heisenberg. "Most cops think they're better than everyone else". "Yes - I hate inequality" adds Bell. "Though you *were* speeding" says Faraday to Heisenberg. "I carefully observed the needle creep from 35 to 55". "Actually, it went up in jumps, Michael" replies Planck. "I couldn't see it because of the condensation" says Bose. "Please keep it under 0.07, Werner" says Mach. "In which frame of reference?" asks Albert. "Hey, Max" says Heisenberg, "If you loan me a tiny bit of money, I'll pay it back so quickly you'll never notice it was gone". As they pile back into the car, Bohr says "See here - you must fill the seats in order - no empty spaces allowed. And stop interfering with each other!" "Only one of you can sit next to me!" yells an agitated Pauli. "I need my own space" grumbles Minkowski. "Say, Werner - it's stuffy in here. Be a good chap and crack the window a bit" says Hawking. "Sorry, Stephen. It can be all the way up or all the way down, but nowhere in between" replies Heisenberg. "Hey guys - Albert and I just figured out a great shortcut. Only one bridge" announces Rosen. "It will save us a lot of distance" says Einstein, "but it might get spooky". "We could just tunnel" says Hund. "I prefer left-hand turns" says Madame Wu. Arriving at the beach the next morning, they hurry from the car and stand looking out over the ocean. "Look at the wonderful waves" says Schrodinger. "They don't look like waves to me" says Bohr. "This is not my idea of a sea" opines Fermi. Looking down at the fine sand, Dirac exclaims "Look at all the particles!" "Now *those* look like waves" says De Broglie. "This is great!" exclaims Feynman, rubbing his hands together. "Now, lets go meet some girls!" "Sounds good to me!" exclaims Schrodinger. "Let's delay" says Wheeler. "We have to be discrete" warns Bohm. "I need to shave first" says Occam. "What are girls?" asks Newton. 1 Based on, and including the original joke attributed to Rich Granger, Engineer, Battelle.

I still do not understand how they come up with those formulas. Has the formula proven to be right? Also how is it possible to instill a formula from your own observations?

[@fanimeproductionst.v.3735]

I think its kind of intuitive in a sense. Like how profit equals sales minus the cost to make the product

[@UjwalAroor]

It is intuitive sure but usually it is through experiments or observations.For example let us derive the formula for force: Now if you push something with your hand,you know that there are only 2 factors affecting the force you apply.They are the velocity of your hand and the mass of your hand.We have a neat concept called momentum which is mass into velocity.So we have to find some relation between force and momentum.If you push a 1kg block and a basketball with the same force,their resulting momentum will be different.However Newton realised that the rate of change in momentum is the same.So he made the second law of motion which states that the force applied is proportional to rate of change of momentum.So if you write down this equation and solve you will have derived the equation for force. As you can see we had a goal of finding an equation for force.So we performed some experiments and derived it.Formulas like these are proven to be right as many scientists recreate such experiments or try to proofcheck others work.To instill your own formula try to get relation between certain quantities like the above experiment.If you have some time to kill,try to derive the velocity of a bob in a pendulum. Cheers

[@alh3328]

Through experiments. Observation is one thing, you need to run some tests then after that you need to compare your data. After comparing your data you will either have to do more experiments or a formula can be drawn up and tested to check its accuracy. The formula will come from the experiments.

I went into engineering with the wrong intentions of trying to peruse a career I wasn’t really passionate about. I enjoy physics and math. I realized I loved the abstract side of math, and I decided to peruse pure math for that reason Vs applied math after a semester.

Do germans have to be good spellers, your words are so long

[@fang8459]

@@ryanjones9498 tbh, the only reason that german words are so long is because we don't seperate words, we just make them into one long word. I.e. car insurance in english are two words, while we just put them into one: Autoversicherung. Auto meaning car and Versicherung meaning insurance. So they're not even that long if you split them up into the words they originate from. Thats why spelling isn't much more of an issue in german than i english. :D same goes for Röntgenstrahlen. Just the name Röntgen and the word Strahlen meaning rays. Fun fact: there's even a game where we try to add onto a word as long as we can. So one would say Auto, the other would say Versicherung, another would say Makler (the person selling you the insurance) and it would still be a valid (although uncommon) word: Autoversicherungsmakler. As in, a person selling car insurances.

About the planets moving along ellipses: Johannes Kepler had found, after many years of going down blind alleys, that the orbits of the planets could be accounted for by describing the orbit as an ellipse, with the Sun at one focus, and with the velocity of the planet as a function of time described by Kepler's law of areas. Contemporaries of Newton such as Robert Hooke, Christopher Wren, Edward Halley and others were aware and discussed that that an inverse square law of gravity was a plausible way to account of the ellipse-shaped orbits (and to account for Kepler's third law), but the mathematical apparatus to give a proof of that did not exist yet. Among the many innovations in the Principia Newton showed mathematically that indeed the orbits of the planets can be accounted for as a consequence of an inverse square law of gravity. (Incidentally, the mathematical apparatus that Newton used in the Principia was not practical. However, knowing that Newton had proved it meant that other scholars knew it should be possible to reproduce Newton's results using the differential calculus introduced by Leibniz. (Introduction of Leibniz's differential calculus was several decades after the publication of the Principia.)) Back to the planets moving along ellipses: t's not just that you've skipped Kepler's work, you make it seem as if it was only after Newton's work that scholars shifted from assuming circular orbits for the planets to thinking in terms of ellipse-shaped orbits. I'm aware of course: your aim here is to do a history of physics of 40 minutes or so; only very few events will make the cut. That said: while you have to be very selective, you mustn't *distort* history. This was an unforced error; you had the option of not distorting history while not using extra time.

I think Galileo did not do the pisa experience... if you do the heavier will reach the earth faster do to friction. So inconclusive... instead he demonstrate it. A clean demonstration. Suppose Aristote was correct. Then the watermelon should reach earth before the apple. Now you tie by a rope the apple to the water melon. Following aristote, the watermelon+apple should reach the earth before the watermelon alone. But following aristote as well, the system watermelon+apple should actually arrive after the watermelon since the apple will act as a parachute and slow down the system. The conjecture of aristote is therefore inconsistent... and then both case will reach earth at same time.... super nice no?

How would the heavier one reach the earth faster due to friction? Friction and weight are two different forces. And both of the balls Galileo used had the same circumference so the friction would be identical.

Balancing the crown w/ an equal mass of gold is fine so you know m1 = m2, but placing them in water wouldn't make calculating the presence of silver any easier. Even as you stated, we know that a bigger volume displaces more water, so the crown feels more force anyway. Basically, if the masses are the same, but the crown is more volume, the crown will always float more than the gold, so how would that help show that there's silver in it?

[@thegreatreyrey1]

If they have the same mass, but the crown has more volume, that means the crown has a lower density. Gold has a constant density, so this implies the crown isn't pure gold.

Kepler proved the elliptical motion of planets - not Newton
