The Ancient Greek scientist was trying to find a way of determining whether a crown was made of pure gold. While pondering the problem Archimedes climbed into his bath and saw the water level rise. He realized that he could compare the volume of gold in the crown with a lump of pure gold of the same weight by submerging them and comparing the rise in water level. He leapt out of his bath and cried “Eureka!” (“l have found it!”)

How many Nobel Prizes are there
The Nobel Prizes are named after Alfred Nobel, who left almost all of the enormous fortune he had made from inventing and manufacturing dynamite to establish the awards. Each year, prizes are given for these 7 fields.
- Physics
- Chemistry
- Medicine or Physiology
- Economics
- Literature
- Peace
Leonardo da Vinci’s Timely designed Inventions
Renaissance artist Leonardo da Vinci kept notebooks crammed full of notes for new inventions. Many of these were way ahead of his time:
- Helicopter
- Tank
- Solar-power
- Generator
- Scuba diving
- Suit
- Robot
- Hang gliding
Ingenious but useless
The word chindogu (the Japanese for “weird tool”) describes an invention that does actually work, but which no one would ever really use.
Duster slippers for cats – for helping with housework.
Hayfever hat – a toilet roll headpiece.
Butter in a tube – like a stick of glue.
Solar-powered torch (think about it…).
Noodle eater’s hair guard – stops hair trailing in the noodles.

Five ways to win a Nobel Prize
By mistake! Enrico Fermi received the 1988 Nobel Prize in Physics for discovering new radioactive elements, but it turned out he had just found fragments of existing elements produced by nuclear fission.
Not for the theory of relativity.
Albert Einstein’s theory of relativity is a major scientific discovery, but he won his Nobel Prize in 1921 for proving that light exists in particles called photons.
Find the structure of DNA. James Watson, Francis Crick, and Maurice Wilkins won the 1962 Nobel Prize for Physiology when they discovered the double-helix shape of DNA.
Campaign for peace. Linus Pauling won the 1954 Nobel Prize for Chemistry then followed this with the 1962 Nobel Peace Prize for working to end nuclear weapons testing.
Keep it in the family. Nobel Prize winners in the Curie family include Marie, her husband Pierre, daughter Irene Joliot-Curie, and lréne’s husband Frédéric Joliot-Curie.
Five accidental inventions
Ice cream cones:
An ice-cream stall at the 1904 World Fair in St Louis USA, ran out of dishes. The neighboring stall sold wafer-thin waffles and the stall holder came up with the idea of rolling them into a cone and tapping with Ice cream.
X-ray:
While setting up a cathode ray generator in 1895. Wilhelm Roentgen noticed a faint fluorescent effect on a chemical coated screen in the room. He had discovered invisible X-rays. which pass through cardboard, and paper, but not through bones.
Synthetic dye:
In 1856, William Perkin was attempting to produce synthetic quinine to treat malaria but the experiment produced nothing out a purple mess Perkin spotted an opportunity at once, and set up a factory to produce the first synthetic dye.
Microwave:
A chocolate bar in Percy Spencer’s pocket melted as he stood in the path of radiation from a radar-generating machine in 1945. He put corn kernels in the path of the beams, and they popped. He had discovered the principle behind the microwave oven.
Post-it notes:
In 1968, Spencer Silver was trying to find a new strong adhesive and came up with a glue that didn’t even hold pieces of paper together firmly. In 1974, co-worker Arthur Fry thought of a use for the non-sticky adhesive and the Post-it note was born.
You won’t believe it!
Albert Einstein never did a single experiment. All his ideas were worked out theoretically (with lots of very complicated equations).
