Who was the greatest scientist ever?

Probably the greatest scientist who ever lived was an Englishman named Isaac Newton. He was born in 1642, so his youth was lived out during Puritan times. He died in 1727, eleven years before John Wesley was converted and the great Awakening of Protestant Christianity began. There was never a scientist greater than Issac Newton. Albert Einstein was not nearly as ingenious or creative.

When Newton was twenty-two years old, with only pen, paper, and his own mind, he invented calculus. That achievement alone would have made him one of the greatest mathematicians of all time...

Using the mathematics he had invented, Isaac Newton derived the law of gravity and the mathematical motions of the planets, the moon, the comets, and all moving terrestrial objects. He did this with only pen and paper, with all the computations figured out in his own mind. He didn't have a calculator, a computer, or an internet connection. Isaac Newton had to think for himself. He wrote his scientific findings in his book, "Principia."
