Newton Stole First 2 Laws of Motion From Galileo!

Not only that, Newton also stole the first 2 corollaries as well.

Newton even admitted it.

"Hitherto I have laid down such principles as have been received by mathematicians, and are confirmed by abundance of experiment. By the first two Laws and the first two Corollaries, Galileo discovered that the descent of bodies observed the duplicate ratio of the time, and that the motion of projectiles was in the curve of a parabola; experience agreeing with both, unless so far as these motions are a little retarded by the resistance of the air."

GALILEO SPEAKS. THIS IS THE YEAR OF GALILEI. I AM GALILEO. I HAVE BEEN SENT AS AN AMBASSADOR FROM HEAVEN.

Galileo > Newton.

Evidence please. The thread title makes an assertion, which you have not even attempted to refute. This forum is supposed to be a debate about ideas, not personalities. You have no idea what someone may have done with DNA obtained from Galileo's tomb or Galileo's finger. The possibility of cloning exists.

Uhm, no, he's explaining how his new mathematical theory of motion can explain the observational results reported by Galileo.

Take a ball of mass "m", drop it towards an Earth of Mass "M".

Newton tells us that F=ma, that is, the F force of gravity, will produce an acceleration "a" of the mass "m".

Newton also tells us that the force of gravity F = (GMm)/(r^2)

Thus, we have: F= ma = (GMm)/(r^2). By basic algebra, the "m" term drops out of each side, so we have a = (GM)/(r^2).

This means that, according to Newton's theory, the acceleration due to gravity is not dependent on the mass "m" of the object dropped...which is what Galileo observed.

Hence, Newton's above comment.

wrongola. Newton says that Galileo used the two laws of motion and two corollaries of motion to obtain his results. Hence Galileo discovered those laws.

Newton was notorious for not crediting others for their work, but with the great Galilei he made an exception. Newton went so far as to blot out the names of Descartes, Hooke, and Liebnitz from his manuscripts.

Aren't you supposed to jump out of your chair and shout "objection" before you say that?

Actually Newton's law says that objects of different weights will drop at different speeds. The thing is that the mass of the Earth is so much greater than anything that you would drop the difference disappears in the uncertainty of the equation. On another site I made this point and to prove it I took the two different objects to an extreme and dropped the sun on the Earth. For more typical items that you would actually drop the difference does not appear until past the twentieth digit after the decimal point (actually we used a sponge and a rock and it was the 24th place past the decimal point!). So here Newton outranks Galileo, in a simple case they have the same numbers, with massive objects you must use Newton.

Galileo would never say 'wrongola'. He just wouldn't.

He would also understand how cloning works. Because he's smart. And, well, you're just not.

Oh, and given that you seriously didn't get Horatio's post, or the fact that in the very quote you provided Newton said he has outlined the principles describing what Galileo had observed through experiments. That's kind of the whole point. For somebody who thinks they are the reincarnation of Galileo, I would have thought you might at least be able to read your own quotes.

Maybe if you cloned Newton we'd have a decent debate on our hands. Nothing to see here, folks.

You may believe that. Newton certainly didn't. Newton says that Galileo used 2 laws of motion and 2 corollaries of those laws to figure stuff out.

Note that Newton does not ascribe the inverse square law to Galileo because Galileo did not know that one (although he suspected it, based on his speculations about Plato & the planets). Newton stole the inverse square law from Robert Hooke.

I believe that statement is utterly false!

 

[Subduction Zone]

I believe that statement is utterly false!

That is because you forgot about the motion of the Earth towards whatever object was dropped. As I said, and it is fairly obvious without using the formula, the amount the Earth moves towards a typical dropped object is undetectable, but it is still a "real" value mathematically. The rate of acceleration of the object towards the Earth is the same regardless of mass. But the acceleration of Earth towards another object varies on the mass of the object. It is all within Newton's law.

Got it! But the acceleration experienced by any two objects falling towards the earth is the same, right?

 

[Subduction Zone]

Yes, exactly. The acceleration of the Earth towards the object is so small that it can be ignored until you get to an object the size of a large asteroid, and even then it is barely detectable. Of course the acceleration of the Earth towards the Moon is a well documented and observed phenomenon. Something covered by Newton's law but not by Galileo. Which is why I say that Newton trumps Galileo.

 

[Reality Check]

Newton even admitted it.

"Hitherto I have laid down such principles as have been received by mathematicians, and are confirmed by abundance of experiment. By the first two Laws and the first two Corollaries, Galileo discovered that the descent of bodies observed the duplicate ratio of the time, and that the motion of projectiles was in the curve of a parabola; experience agreeing with both, unless so far as these motions are a little retarded by the resistance of the air."

"Galileo discovered ..." is definitely referring to Galileo's experimental work.

Thus your assertion depends on what Newton mean with "By the first two Laws and the first two Corollaries, " prefixing that statement. I can think of a few interpretations:

1. Galileo's discoveries were because the first 2 laws and first two corollaries existed but had not yet been formulated by Newton.
2. Galileo's experiments were tests of the first 2 laws and first two corollaries which he had already formulated.
3. Galileo's experiments were tests of the first 2 laws and first two corollaries and he formulated them later.

The presence of a comma between the 2 phrases suggests the first interpretation. That is: Galileo did experiments that were governed by the first 2 laws and first two corollaries and got the expected results.

If Newton had mentioned where Galileo had published the equivalent of the first 2 laws and first two corollaries then options 2 or 3 are more likely.

Perhaps you can provide the citation that Newton seems to have forgotten?

I hope you achieve a better result than I did, but I doubt you will.
