Jocelyn Bell Burnell and the Discovery of Pulsars

A composite image of the Crab Nebula showing the X-ray (blue), and optical (red) images superimposed. 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…

Sir Arthur Eddington – The Man who Proved Einstein’s General Relativity

Arthur Eddington (1882 – 1944) On November 22, 1944, British astrophysicist and philosopher Sir Arthur Stanley Eddington passed away. He became famous for his 1919 solar eclipse expedition to Principe, where he conducted astrophysical experiments to give proof for Albert Einstein‘s seminal theory of general relativity. Through hard work and lots of talent, Eddington earned a scholarship to Owens College, where he was able to improve his knowledge in physics. He was…

Hedy Lamarr – a Hollywood Star Invents Secure Communication Technology

Hedy Lamarr (1913-2000) On November 9, 1913, Hollywood movie star Hedy Lamarr was born, co-inventor of an early form of the spread spectrum communications and frequency hopping, necessary for wireless communication from the pre-computer age to the present day. Ok, I assume that you are not necessarelly familiar with spread spectrum communications technology. But, maybe you are wondering even more about a Hollywood movie star diva, who should be responsible for the development…

Sir Edmond Halley (1656-1742)©Klaus-Dieter Keller, wikipedia On November 8, 1656, Sir Edmond Halley was born. The astronomer, geophysicist, mathematician, meteorologist, and physicist, was best known for computing the orbit of the eponymous Halley’s Comet. Edmond Halley was born in England to the family of a wealthy soap maker. Therefore, Halley was able to receive a proper education and started studying at Queen’s College in Oxford, where he already published his first scientific…

The Arecibo Radio Telescope – Looking for Extraterrestrial Signals

The Arecibo radio telescope is the largest single-dish telescope in the world. On November 1, 1963, the Arecibo radio telescope, by that time the earth’s largest radio telescope, has been inaugurated in Arecibo, Puerto Rico. It is operated by the company SRI International under cooperative agreement with the National Science Foundation and is also called the National Astronomy and Ionosphere Center, although “NAIC” refers to both the observatory and the staff that…

Lise Meitner – The Misjudged Genius

Lise Meitner and Otto Hahn On October 27, 1968 the scientist Lise Meitner passed away. She is known today for her passionate and extraordinary work on radioactivity and nuclear physics along with her colleague Otto Hahn, who was honored with the Nobel Prize while Meitner stayed unrecognized. Born in 1878 in Vienna, Lise Meitner’s talents were early detected, not unusual for scientists who achieved these major efforts in their later lives. It was…

Eris – The Planet of Discord

Eris – The Planet of Discord

On October 21, 2003, a photograph of the nocturnal sky was taken, where almost 2 years later, in January 2005, evidence was raised that there might be a 10th planet at the borders of our solar system: Eris, located in the Kuiper Belt and named after the Greek godess of discord. And discord it should be, because Eris as a planet is rather small and astronomers were arguing, whether it is a…

Windscale – A Nuclear Desaster

Windscale – A Nuclear Desaster

Sellafield © Rob Bishop On October 10, 1957, the world’s first major nuclear accident took place. The Windscale fire happened in Cumbria, U.K. and was Great Britain’s worst nuclear accident in history. After World War II, the British refused to just look at how the United States and the Soviet Union raced each other in who can work with nuclear power at first and most important, who is able to launch the…
