Isaac Newton was born prematurely on December 25, 1642, three months after his father's death in October 1642.

Isaac Newton designed and built the first practical reflecting telescope in 1668, using a curved mirror to gather light instead of a lens. This design solved the chromatic aberration problem of refracting telescopes.

Isaac Newton died on March 20, 1727 at the age of 84. He was born in 1642 and lived until 1727, making him 84 years old at his death.

Isaac Newton served as Member of Parliament for Cambridge University from 1689 to 1690. His parliamentary tenure was brief and he reportedly spoke only once during his entire service.

Newton had a well-documented conflict with Robert Hooke over scientific priority. Hooke claimed credit for some optical theories, which led to a bitter rivalry between the two scientists.

Exobiology (also called astrobiology) is the study of potential life beyond Earth. Endobiology is not a standard term for space science, and enterobiology relates to intestinal study.

Daniel Fahrenheit invented the mercury thermometer in 1714, which became widely used in medical practice. Galileo developed an earlier thermoscope, but not a clinical thermometer.

Ole Romer first measured the speed of light in 1676 using Jupiter's moon Io, observing its apparent delay in orbit. Einstein developed relativity theory, Newton studied optics, and Galileo attempted but failed to measure light speed.

Charles Babbage designed the Analytical Engine and Difference Engine in the 1830s, considered the first mechanical computers. Edison invented light bulbs and phonographs, not computing devices.

A seismograph measures earthquake intensity by recording ground vibrations. Barometers measure atmospheric pressure, hydrometers measure liquid density, and polygraphs detect physiological responses for lie detection.
