Stereoscopic visualization is seldom used in Astrophysical publications and presentations compared to other scientific fields, e.g., Biochemistry, where it has been recognized as a valuable tool for decades.
@eufisica Thank you very much for RT. I share this from Universe Today http://t.co/gf1uP1H – ChiliDog Observatory (CCantuQ) http://twitter.com/CCantuQ/status/95262242865561600
Sir Fred Hoyle, born in 1915 was a famous astronomer, mathematician, and author. The scientist was the first to coin the term "Big Bang" for the now prevailing theory of the early development of the universe in 1949, even though he happened to be a strong opponent of this theory.
From the invention of a new power source or engine up to a vehicle that applies this power source to move forward sometimes is only a small step. But, to become a commercial success, this step might take even decades. Just think of the oldest type of engine powered by steam.
On October 2, 1608, German-Dutch lensmaker Hans Lippershey applied to the States-General of the Netherlands for a patent for his instrument "for seeing things far away as if they were nearby".
Written by Patrick Chan (NASA Summer Intern 2001 Duke University sophomore), ThermoBuild is an interactive tool which uses the NASA Glenn thermodynamic database to select species and to obtain:
Tables of thermodynamic properties for a user-supplied temperature schedule.
Data subsets for use in CEA, SUBEQ or any other computer program.

On September 22, 1791, the famous chemist and physicist Michael Faraday was born. He is responsible for the discovery of the electromagnetic induction, the laws of electrolysis and best known for his inventions, which laid the foundations to the electrical industry.
On January 3, 1851, French physicist Leon Foucault started to experiment with his eponymous pendulum, by which he was able to proof the earth's rotation. Actually, how can you prove that the earth is a rotating orb in an easy-to-see experiment and - of course - without space flight? By today, Foucault's simple device is part of numerous natural science museums around the world.
On December 20, 1910, New Zealand born physicist Ernest Rutherford made his seminal gold foil experiment which led to first insight about the nature of the inner structure of the atom and to the postulation of Rutherford's concept of the "nucleus", his greatest contribution to physics. Most interestingly, Rutherford made his greatest discovery after receiving the Nobel Prize in chemistry in 1908.
On April 23, 1882, German mathematician and physicist Emmy Noether was born, who is best known for her groundbreaking contributions to abstract algebra and theoretical physics. Albert Einstein called her the most important woman in the history of mathematics, as she revolutionized the theories of rings, fields, and algebras.
On May 24, 1686, Dutch-German-Polish physicist, engineer, and glass blower Daniel Gabriel Fahrenheit was born. He is is best known for his invention of the mercury-in-glass thermometer in 1714, and for developing a temperature scale that is now named after him.
On November 28, 1967, Jocelyn Bell Burnell and Anthony Hewish discovered the first Pulsar, a fast rotating neutron star that emits a beam of electromagnetic radiation. The radiation of a pulsar can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission.
On March 31, 1596, French philosopher, mathematician, and writer René Descartes was born. The Cartesian coordinate system is named after him, allowing reference to a point in space as a set of numbers, and allowing algebraic equations to be expressed as geometric shapes in a two-dimensional coordinate system. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution and has been described as an example of genius. He has been dubbed the 'Father of Modern Philosophy'. His Meditations on First Philosophy continues to be a standard text at most university philosophy departments.
After a brief review of the golden ratio in history and our previous exposition of the fine-structure constant and equations with the exponential function, the fine-structure constant is studied …
