"the epic feud between Sir Isaac Newton and Gottfried Leibniz over who invented an astonishingly powerful new mathematical tool: calculus."
Isaac Newton: Physicist and… Crime Fighter?
From NPR’s Science Friday:
Isaac Newton is best known for his studies of physics and for developing the three basic laws that describe motion. In Newton and the Counterfeiter, author Thomas Levenson describes another side of Newton: his career as the crime-fighting head of the Royal Mint.

The Physics of Time
When writing the Principia Mathematica, Isaac Newton declared his hand on most of the big questions in physics. He outlined the nature of space, explained the motions of the planets and conceived the operation of gravity. He also laid down the law on time declaring:
“Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.”
For Newton time was absolute and set apart from the universe, but with the theories of Albert Einstein time became more complicated; it could be squeezed and distorted and was different in different places.
Time is integral to our experience of things but we find it very difficult to think about. It may not even exist and yet seems written into the existence of absolutely everything.

NPR Science Friday : Can scientific reasoning be taught?
Scientific reasoning is essential to a successful career in science. But research in the journal Science claims this skill can’t be learned through memorization of facts alone. Author Lei Bao explains the findings, and how teachers can apply them in the classroom.
