Newtons Experiments

Quote:

Original post by Cibressus Today i had a relization. in mechanical physics, thier are two major equations. force: F=MA force is equal to the product of a objects mass and acceleration and impulse: F∆T = M∆V now how did newton calculate the ammount of time a objeect was in contact with another object using eyesight and 17th century clocks? and for that matter, how did he calculate acceleration?

Calculus and derivatives. :)

explain how using calc would solve anything, you have to come up with experimental results before you can formulate a forula.

He used Genius.

Did he follow a scientific method did he? specificly do you think that Cambridge would have logs of his experimental method?

And I, for one, would love to know how he imbues such wholesome, lip-smacking goodness in every delectable fig-filled cookie.

I'm waiting eagerly for someone to declare Newton's methods wrong and therefore his laws to be incorrect.

Ofcousrse. You will be well served to read some biography of his and also googling isaac newton experimental techniques. He was a master of such. Newton was an amazing man, especially his confrontations with Hooke, and maybe Leibniz. Great.

Without attacking his methods I am going to say Newtons laws are wrong. Blatantly so when we look at mercury. :p

oh, the missing orb...

ridiculous book btw

Why do you suggest his laws are wrong, specifically for mercury?

Um, his laws *are* incorrect, as shown by Einstein.

lol, ok must read up a bit now then. thanks.

When calculating with gravity, he let things roll down instead of falling free. That slowed the process down:

I think it was Newton also that used music to count small timesteps. He hummed some melody, and because of that he could keep track of fractions of a second. "Seconds" were defined as a heartbeat.

Some other scientist let the lights go on and off repeatedly, making what he saw appear to be in slow motion (when you see a sudden flash of something, the image kind of burns to your mind).

edit: Writing backslashes in [ code ]-enviroments is buggy!

His laws are incorrect in the general case (includes large masses and close to c velocities) but correct in the particular cases (small velocities, no large masses). Absolute corectness does not exist, science approaches truth asymptotically (see Karl Popper): Einstein's laws don't work everywhere (see quantum mechanics), does it mean they're incorrect?

If you all have taken enough math you'll find that pretty much everything is approximations. Just like Ilici said.

I meant, declare Newton wrong based on his experimental methods alone, relativity and quantum mechanics notwithstanding.

Ofcourse, the mere existance of singularities is sufficient to indicate a possible fallacy without the need of bringing up its inability to properly describe space at the microscopic level.

I know Promit, I was just messing. [grin] I assumed you knew that I knew you would know that I know that you know what you are talking about.

Yes, obviously.

Brilliantly put.
