Orbital Dynamics by NASA

This excellent web site from NASA explains a lot about how orbits work. A geosynchronous orbit at an altitude of 35,786 kilometers (above sea level) allows a satellite to orbit at the same rate the Earth turns, so it always remains over the same spot on the planet below. Lagrange points are orbital sweet spots […]

1765 – Ruffini – bio

Paolo Ruffini was born in Italy in 1765 and was a mathematician. After the cubic equation was solved in 1539 by del Ferro, Tartaglia and Cardano, and Ferrari had solved the quartic equation by 1545, mathematicians turned their attention toward attempting to solve the quintic. The previous polynomial equations (quadratic, cubic and quartic) had all […]

1700 – Bernoulli – bio

Daniel Bernoulli was born in 1700 in the Netherlands and became a mathematician known for his work with fluid dynamics and probability and statistics. In fluid mechanics, “Bernoulli’s Principle” describes the relationships involved amongst fluid speed, pressure differential and potential energy. PRECURSOR: 1627 – Boyle 1642 – Newton 1646 – Leibniz 1662 – Boyle’s law […]

1768 – Fourier – bio

Jean Babtiste Joseph Fourier (known as Joseph) was born in 1768 in France and was a mathematician who became known for his work on heat transfer and the analysis of periodic functions (wave forms) using combinations of trigonometric series. These are now called Fourier series and the process is called Fourier analysis. PRECURSOR: 1642 – […]

1736 – Lagrange – bio

Guiseppe Lodovico Langrangia, aka Joseph Louis (Luigi) Lagrange was born in 1736 and grew up in Turin, Italy, but also lived in Prussia and France. He is primarily known as a mathematician but also made contributions to astronomy. Euler and Lagrange collaborated to create the Euler-Lagrange equation and created the field called calculus of variations. […]

1642 – Newton – bio

Isaac Newton was born in 1643 in Linconshire, England. He made exceptional contributions to physics, mathematics and astronomy and was also accomplished in philosophy and theology. His laws of motion and gravity became landmarks for centuries. He and Leibniz independently developed calculus. He investigated the refraction of light and created the first working reflecting telescope. […]
