A Wire to Connect the World – Stephen Gray’s Discovery

A Wire to Connect the World – Stephen Gray’s Discovery

In a famous experiment Stephen Gray demonstrated static electricityby charging a boy suspended by insulating strings in 1744 Today for us it’s pretty normal that electricity can be transmitted on a wire, because it’s part of our daily life. But, in the early 18th century, when the English nature-scientist Stephen Gray was able to show that electricity really can be transmitted on a string of copper, it was an unheard-of…

To Boldly Go Where No Man Has Gone Before – Voyager 2

Jupiter with the great red spot shot from Voyager 1© NASA/CalTech/JPL On July 9, 1979 the interplanetary spacecraft Voyager 2 passed Jupiter, the largest planet in the Solar System. The space probe had been launched by NASA on August 20, 1977 to study the outer Solar System and eventually to push forward into interstellar space. Until today,  operating for more than 30 years the spacecraft still receives routine commands and…
The misjudged Math Teacher – Georg Simon Ohm

The misjudged Math Teacher – Georg Simon Ohm

Georg Simon Ohm(1789 – 1854) On this day in 1854, the Bavarian physicist and mathematician Georg Simon Ohm passed away, he was best known for his research on electricity and it was him to initiate the subject of circuit theory. The SI unit of electrical resistance and Ohm’s law are named after this Bavarian ‘teacher’. Ohm’s intention was to develop a formula dealing with the effects of flowing electricity and…
Sir Isaac Newton and the famous Principia

Sir Isaac Newton and the famous Principia

Sir Isaac Newton (1642 – 1727) On July 5, 1687, Sir Isaac Newton published his Philosophiae Naturalis Principia Mathematica (in Latin). It is to be considered as the most influential work of Sir Isaac Newton and as one of the greatest scientific works of all time. The original impulse to work on the Principia gave Edmund Halley, the English scientist known for his calculations on the orbits of comets and for…
The Supernova of 1054

The Supernova of 1054

  On July 4, 1054, 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…
The Annus Mirabilis in Physics – Albert Einstein and the Year 1905

The Annus Mirabilis in Physics – Albert Einstein and the Year 1905

Albert Einstein (1879-1955)from Scientific Monthly 10:4 (1920) Have you ever heard of the “Annus Mirabilis” (in German “Wunderjahr“) of physics? 1905 was this Annus Mirabilis, this year of wonders or extraordinary year. History considers 1905 as the year with the most outstanding and influential papers ever published by famous phycisist Albert Einstein in the   the Annalen der Physik scientific journal. These four articles contributed substantially to the foundation of…

Jack Kilby – Inventor of the Integrated Circuit

Jack Kilby1923 – 2005 7 years ago today, physicist and inventor Jack St. Clair Kilby passed away. He was best known for creating the integrated circuit, the basis of almost all electronic devices operating today. At the age of 35, the electrical engineer Kilby began his career at Texas Instruments and spent all summer in his lab, trying to find solutions for a problem in circuit design typical for the…
Benjamin Franklin and the Lightning Rod

Benjamin Franklin and the Lightning Rod

Benjamin Franklin 1706 – 1790 On June 15, 1752, Benjamin Franklin proved that lightning is electricity and invented the lightning rod through his experiments with kites. As you might know for sure, Benjamin Franklin wasn’t only an enthusiastic scientist, inventor, and author, but also one of the Founding Fathers of the United States. His roots lay back in Boston, where he was born in 1706 as the son of a…

Karl Ferdinand Braun (1850 – 1918) On June 6, 1850, inventor and engineer Karl Ferdinand Braun was born. The Nobel laureate (1909) is known for his significant improvement of radio and television technology in the Wilhelmine Period. Karl Ferdinand Braun was born in Fulda and spent his first university years in Marburg. He studied mathematics as well as natural sciences and became a member of the German student corp Teutonia…
And Kepler Has His Own Opera – Kepler’s 3rd Planetary Law

And Kepler Has His Own Opera – Kepler’s 3rd Planetary Law

Kepler’s Model of the Solar System from Mysterium Cosmographicum (1600) On May 15, 1618, famous astronomer Johannes Kepler discovered the 3rd and also last of his planetary laws, and concluded the general revolution of our celestial world that started with Nikolaus Kopernikus about 100 years earlier. And that made him rather popular as he still is today. Did you know that there is a Kepler crater on the Moon, a Kepler…
