Blaise Pascal
Blaise Pascal (1623–1662) studied fluid hydrodynamics and hydrostatics, centered on the principles of hydraulic fluids. His inventions include the hydraulic press, which multiplied a smaller force acting on a larger area into the application of a larger force totaled over a smaller area, transmitted through the same pressure (or same change of pressure) at both locations. Pascal's law or principle states that for an incompressible fluid at rest, the difference in pressure is proportional to the difference in height and this difference remains the same whether or not the overall pressure of the fluid is changed by applying an external force. This implies that by increasing the pressure at any point in a confined fluid, there is an equal increase at every other point in the container, i.e., any change in pressure applied at any point of the fluid is transmitted undiminished throughout the fluids.

Famous quotes by blaise pascal:
“Those great efforts of intellect, upon which the mind sometimes touches, are such that it cannot maintain itself there. It only leaps to them, not as upon a throne, forever, but merely for an instant.”
—Blaise Pascal (1623–1662)
“When we read too fast or too slowly, we understand nothing.... Too much and too little wine—give him none, he cannot find truth; give him too much, the same.”
—Blaise Pascal (1623–1662)
“We like the chase better than the quarry.... And those who philosophize on the matter, and who think men unreasonable for spending a whole day in chasing a hare which they would not have bought, scarce know our nature. The hare in itself would not screen us from the sight of death and calamities; but the chase, which turns away our attention from these, does screen us.”
—Blaise Pascal (1623–1662)
“The last thing one discovers in composing a work is what to put first.”
—Blaise Pascal (1623–1662)
“We know then the existence and nature of the finite, because we also are finite and have extension. We know the existence of the infinite and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because he has neither extension nor limits.”
—Blaise Pascal (1623–1662)
