That is, its axis is not perpendicular to the plane of its orbit. Its axis is tilted at an angle of 23 and a half degrees. The Earth's axis is always tilted in the same direction in space. This means that, as the Earth travels each year around the Sun, the axis is tilted alternately towards, then away from the Sun. Naturally, when the northern hemi...

  Starting about 1665, at the age of 23, Newton enunciated the principles of mechanics, formulated the law of universal gravitation, separated white light into colors,proposed a theory for the propagation of light, and invented differential and integral calculus. Newton's contributions covered an enormous range of naturalphenomena: He was thus able to show that not only Kepler's laws of planetary motion but also Galileo's discoveries of falling bodies follow a combination of his ownsecond law of m...
