### Blaise Pascal

__About__*BLAISE**PASCAL*Died in the Year: 1662.

Blaise

*Pascal*was a

*French Scientist*. From his childhood, he showed more interest in geometry. With his curiosity and analytical thinking, he proposed a theory that the sum of the three angles in a triangle is equal to the sum of two right angles. His father an accountant. To help his father in calculations he designed a machine, later on, it leads to developing a calculator.

His contributions to the Science:

- Pascal showed that the sum of the three angles in a triangle is equal to the sum of two right angles.
- He designed a theorem called the Universal theorem of geometry.
- Pascal designed a machine to do calculations like sums, subtractions, multiplications, and divisions.
- He is famous for his theory of Pascal's law in physics i.e. pressure at a point in a liquid is the same in all directions.
- Based on Pascal's law Hydraulic lifts and Hydraulic breaks are designed.
- He did research on Geometry, Probability, Hydrostatics, Integral calculus, etc.
- Galileo stated that the air has weight. Pascal proved Galileo's statement experimentally.
