One beautiful Fall day seventeen years ago I wandered into an office and my life profoundly changed. I was an undergraduate at Princeton, and was looking for a thesis advisor. Jadwin Hall was an intimidating place. Plenty of names familiar from my textboo
astrophysicist John Dubinski's self-published DVD containing his stunning supercomputer simulations of galactic evolution set to Bach music. "... Gravitas points clearly at ties between the ideas of Isaac Newton and the music of Bach. To do this with sounds and images that appeal to club kids and new music fans equally is a major achievement." - John Terauds, Toronto Star, March, 9 2006
On October 2, 1608, German-Dutch lensmaker Hans Lippershey applied to the States-General of the Netherlands on October 2, 1608, for a patent for his instrument "for seeing things far away as if they were nearby".
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.
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.
A controversial observation suggests that a constant of physics actually varies in space – it could explain why our corner of the cosmos is just right for life
Natural Science is an international journal dedicated to the latest advancement of natural sciences. The goal of this journal is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in different areas of natural sciences. All manuscripts must be prepared in English, and are subject to a rigorous and fair peer-review process.

On July 11, 1382, significant philosopher of the later Middle Ages Nicole Oresme passed away. As for many historic people of the middle ages, his actual birthdate is unknown and can only be fixed to a period between 1325 and 1330. Nicole Oresme besides William of Ockham or Jean Buridan -- a French priest who sowed the seeds of the Copernican revolution in Europe -- is considered as one of the most influential thinkers of the 14th century and he wrote influential works on economics, mathematics, physics, astrology and astronomy, philosophy, and theology.
The last transit of Venus took place recently on 5 and 6 June 2012, and it was the last Venus transit of the 21st century. Venus transits are very rare events. The next one will be December 10–11, 2117. So it is much likely that this on was the very last Venus transit I had a chance to see in my lifetime.
On October 5, 1644 (or according to the old julian calendar September 25), Danish astronomer Ole Christensen Rømer was born. He is best known for making the first quantitative measurements of the speed of light.
On March 28, 1749, French mathematician and astronomer Pierre Simon marquis de Laplace was born, whose work was pivotal to the development of mathematical astronomy and statistics. One of his major achievements was the conclusion of the five-volume Mécanique Céleste (Celestial Mechanics) which translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems.

On June 6, 1436, German mathematician, astronomer, astrologer, translator, instrument maker and Catholic bishop Johannes Müller aus Königsberg was born, better known under the Latinized version of his name as Regiomontanus. His diligent and accurate observations, measurements and recordings paved the way for modern astronomers such as Tycho Brahe and Nikolaus Copernicus.

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 7.2 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 7.9 million records maintained by our collaborators.
On January 4, 1643, Sir Isaac Newton, famous physicist, mathematician, astronomer, natural philosopher, alchemist and theologian, was born. With his Principia he laid the foundation of modern classical mechanics.Besides he constructed the very first reflecting telescope and independent of Gottfried Wilhelm Leibniz developed differential and integral calculus.
958 years ago today, Chinese astronomers observed a new star in the constellation of Taurus, which later turned out to be a supernova.
China was able to contribute to the developments in the science of astronomy critically. In their philosophy, the harmony between earth, the sky and humankind were essential, and therefore any disturbance to that balance had to be predicted. This believe caused the astronomers of the historical China a great status, they were able to predict comets like no other culture. Also, the precise predictions were caused by the critical consequences the responsible astronomer had to face in case of a false prognosis.
