How Intuition Messed Up the Laws of Motion
A most fundamental problem, for thousands of years
wholly obscured by its complications, is that of motion.
All those motions we observe in nature that of a
stone thrown into the air, a ship sailing the sea, a cart
pushed along the street are in reality very intricate.
To understand these phenomena it is wise to begin
with the simplest possible cases, and proceed gradually
to the more complicated ones. Consider a body at rest,
where there is no motion at all. To change the position
o...And it took a Newton to determine what was really going on.

Laws of Motion
LAW I.
Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon.
Projectiles persevere in their motions, so far as they are not retarded by the resistance of the air, or impelled downwards by the force of gravity. A top, whose parts by their cohesion are perpetually drawn aside from rectilinear motions, does not cease its rotation, otherwise than as it is retarded by the air. The greater bodies...The original source of these laws from Newton.

Science Rewards Those Who Disprove
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton. Einstein is famous for finding a flaw in Newton's contributions.

In the Beginning According to Einstein
In the beginning (if there was such a thing), God created Newton’s laws of motion together with the necessary masses and forces. This is all; everything beyond this follows from the development of appropriate mathematical methods by means of deduction. There was Newton's laws, from which all else naturally followed.

Science is the Knot Tying it all together
The creation was a concept—a connected set of concepts. There was the concept of a universal gravitation-reaching beyond the tree tops and the air to the ends of space. There was the concept of other universal forces in space, which ti to pull the moon away as a whirling stone pulls away fro: its string. And there was the concept which put an end to the four elements of Aristotle: the concept of mass, alike in t apple and the earth and the moon, in all earthly and heavenly bodies.**

Folksonomies: science scientific process
Throughout the centuries, scientists postulate hypotheses, and later scientists connect them to others to form stronger, more universal theories.
