Are Newton´s asumptions really true?

How about some demonstrations? You have been asked before but all we get is bullshit. We know that you can talk the talk, now walk the walk

What are your thoughts on subatomic particles?

Inertia intrigues me, for example the kinetic energy in a fired bullet is tremendous, but what exactly IS kinetic energy?
The k.e. in our bodies must be tremendous too because we're orbiting the sun at 66,000 miles per hour, but there's no way the k.e. in us can be measured..

Seriously, since this guy (a) seeks negative attention and (b) doesn't care at all whether what he says is true, clearly the only way to deal with him is to ignore him. The attention you're giving him is enabling him and has no chance of producing any result other than gratifying his attention seeking. He's drawing the thing out as long as he can, but you all are helping him.

Science and mathematics as taught in our public educational institutions have been dumbed down and rigged to prevent exploration into sensitive areas. This is done through tricks of logic that play upon the intellect’s many vulnerabilities, namely the inability to differentiate absolute from relative values. Certain concepts and variables are discarded on the basis of irrelevance or arbitrariness, when in actuality they are far from arbitrary and instead provide the doorway to secret sciences. Subjects are frequently taught in compartmentalized and overly abstract ways to prevent students from understanding subjects on a gnostic level, meaning on a geometric and intuitive foundation. The latter is necessary to allow true progressive and creative use of knowledge, but what is encouraged instead is applying formulas and definitions in mechanical ways, resulting in refinement rather than evolution of knowledge.

Another thing that fascinates me is magnetism, but we take it so much for granted that we tend to overlook its mysterious properties.
For example if two bar magnets are pushed towards each other on a table north-to-north or south-to-south, they repel each other like a sci-fi force field, wow..
So what exactly is happenning to the space between those two poles, is it being warped or compressed or what?

A sensible question. Unless a velocity is an appreciable fraction of light speed, the formula is:

E = 1/2 m v^2

[b]But bear in mind that velocity is relative.[/b] It only has meaning in the sense that "Object A has a velocity of 123 relative to object B." Relative to object C, it might have a different velocity.

Quick correction parados, to make sure the science is correct.

The floor does zero work holding you up. It is a force, but not a force acting over a distance.

Newton's assumptions work for most applications.
I'm right, ain't I?
