Isaac Newton

11 questions · Science

When Isaac Newton was born in Woolsthorpe, England, in 1643, he was so tiny and frail that no one expected him to survive and he never knew his father, who had died months earlier. The lonely, brooding boy grew into a Cambridge student who devoured mathematics. Then, in 1665, the plague broke out and closed the university. Newton withdrew to the family farm and in these "miracle years" of seclusion he single-handedly laid the foundations of three fields at once: calculus, optics and the theory of gravity. The famous falling apple that supposedly inspired his idea of gravity belongs to exactly this time. In 1687 his masterwork, the "Principia Mathematica", appeared. In it he formulated the three laws of motion and the law of universal gravitation: the same force that makes an apple fall keeps the Moon in its orbit. With a prism he split white light into the colours of the rainbow and built the first practical reflecting telescope. Newton was as brilliant as he was combative. With Gottfried Wilhelm Leibniz he fought a long, bitter dispute over who had first devised calculus. Later he became president of the Royal Society and even Master of the Mint, relentlessly hunting counterfeiters: sending some to the gallows. When he died in 1727 he was the first scientist ever to be buried in Westminster Abbey; a state funeral for the man who had wrested its laws from the universe.

All questions with answers

When and where was Isaac Newton born?

Show answer

1643 (Woolsthorpe)

His father had died before he was born.

💡 Did you know? Newton was born prematurely in 1643, so small he „could have fit in a quart mug“: yet lived to 84.

What is the title of Newton's main work of 1687?

Show answer

Principia Mathematica

It contains the laws of motion and the theory of gravity.

💡 Did you know? Newton's „Principia“ is considered one of the most important scientific works of all time.

Which famous law did Newton formulate?

Show answer

law of gravitation

The same force makes the apple fall and keeps the Moon in orbit.

💡 Did you know? Newton's law of gravity explains both the falling apple and the Moon's orbit with a single formula.

How many of Newton's laws of motion are there?

Show answer

three

Inertia; force = mass · acceleration; action = reaction.

💡 Did you know? Newton's three laws of motion are still the foundation of classical mechanics.

What did Newton split with a prism?

Show answer

white light (spectrum)

He showed white light is made of all colours.

💡 Did you know? With a prism Newton split white light into the colours of the rainbow: showing colour lies in the light itself.

Which branch of mathematics did Newton co-found?

Show answer

calculus

Independently but at the same time as Leibniz.

💡 Did you know? Newton developed calculus: the mathematical tool without which modern physics would be unthinkable.

With whom did Newton feud over the invention of calculus?

Show answer

Leibniz

A bitter years-long priority dispute.

💡 Did you know? Newton and Leibniz feuded bitterly over who invented calculus first: both did so independently.

What type of telescope did Newton build?

Show answer

reflecting telescope

It uses mirrors instead of lenses, avoiding colour errors.

💡 Did you know? Newton built the first working reflecting telescope: more compact and sharper than the refractors of his day.

Which state office did Newton hold?

Show answer

Master of the Mint

He relentlessly prosecuted counterfeiters.

💡 Did you know? As Master of the Mint, Newton pursued counterfeiters relentlessly: some ended on the gallows.

Where was Newton buried?

Show answer

Westminster Abbey

The first scientist ever: a state funeral in 1727.

💡 Did you know? Newton was the first scientist honoured with a state funeral in Westminster Abbey.

Which scientist is shown here?

Show answer

Isaac Newton

Isaac Newton formulated the law of gravity and the laws of motion, laying the foundation of classical physics.

💡 Did you know? The famous falling-apple story comes from Newton himself: though he never claimed the apple hit him.
