Question

Wilhelm Röntgen
Wilhelm Roentgen
Lived 1845 – 1923
Wilhelm Röntgen was a physics professor. He received the very first Nobel Prize in Physics in 1901 for his discovery of X-rays.

Within two weeks of first generating X-rays he had invented X-ray photography. The first ever X-ray photograph was of the bones in his wife’s hand.


When his university, the University of Würzburg, realized how dramatically X-rays would transform the diagnosis of bone injuries and diseases, it awarded Röntgen an honorary degree in medicine.

The discovery of X-rays was perhaps the single most important event in atomic and molecular science.

Archimedes
archimedes
Lived c. 287 BC – c. 212 BC
Archimedes is the best known mathematician and scientist from ancient times. In addition to brilliant discoveries in mathematics and physics, he was also an inventor.
The Archimedes’ Screw
Still in use today, one of Archimedes’ greatest inventions is the Archimedean Screw.
Archimedes probably invented this device when he visited Egypt, where it’s still used for irrigation. The screw is also helpful for lifting finely divided solids such as ash, grain, and sand from a lower level to a higher level.

Robert Hooke
Lived 1635 – 1703
Robert Hooke discovered plant cells and discovered Hooke’s Law – the law of elasticity. He also:

invented the balance spring, vital for accurate timekeeping in pocket watches
invented a machine that cut teeth for cogs used in watches – these cogs were cut in finer detail than any person could have managed, enabling more delicate watch mechanisms to be developed.

Benjamin Franklin

Lived 1706 – 1790
Benjamin Franklin discovered one of the fundamental laws of physics – the Law of Conservation of Electric Charge – and proved that lightning is electricity. He also:

invented bifocal spectacles
invented the Franklin stove
invented the lightning rod

Alessandro Volta

Alessandro Volta was the first person to isolate methane gas. He discovered that methane mixed with air could be exploded using an electric spark: this is the basis of the internal combustion engine. He also found that electric potential in a capacitor is directly proportional to electric charge.

Oh, and he invented the electric battery!
