Daniel's father Johann said there was no money in maths and sent him to study medicine in Basel in Switzerland. While he studied medicine, he studied his father's theories on Kinetic energy. He applied this to his medical studies and wrote on how breathing worked.

Daniel tried to get jobs in Maths but failed so he went to Venice to study practical medicine. While there, he got sick and worked on Maths instead. He published Mathematical exercises. He wrote about the flow of water from a container and discussed Newton's Theories. His medical work on the flow of blood and blood pressure also gave him an interest in fluid flow.

He also designed an hour glass to be usd at sea that the trickle of sand always remained the same, even when the ship was in heavy seas. He won a prize for this in Paris. Because of this, he got offered a job in Russia along with his brother. However eighteen months later his brother died and he was very sad. His father sent his pupil Euler in 1727 to work with him. For the next six years, Bernoulli produced a lot of his best work.

Daniel entered for the Grand Prize of the Paris Academy in 1734, presenting his ideas on astrony. His father also entered the competition and he and Daniel were joint winners. As a result, Daniel's father banned him from the house!

When a giant airplane leaves the ground and becomes airborne, Daniel Bernoulli's principle comes into play - only Bernoulli used liquid instead of air.

We will be looking at why this is so over the next couple of weeks.
