Tabea Tietz
On July 16 , 1888, Dutch physicist and Nobel Laureate Frits Zernike was born. He is best known for his invention of the phase contrast microscope, an instrument that permits the study of internal cell structure without the need to stain and thus kill the cells. “I am impressed by the great limitations of the human mind.

Faster than the Speed of Light – Pavel Cherenkov and the Cherenkov Radiation

Faster than the Speed of Light – Pavel Cherenkov and the Cherenkov Radiation

Tabea Tietz
On July 15, 1904, Soviet physicist Pavel Alekseyevich Cherenkov was born. He shared the Nobel Prize in physics in 1958 with Ilya Frank [4] and Igor Tamm for the discovery of Cherenkov radiation, made in 1934. Cherenkov radiation is a faint blue light emitted by electrons passing through a transparent medium when their speed exceeds the speed of light in that medium. This sounds pretty weird, doesn’t it. With Einstein he have learned…

Andrée, the first Swedish balloonist, proposed a voyage by hydrogen balloon from Svalbard, Sweden to either Russia or Canada, which was to pass, with luck, straight over the North Pole on the way. Unfortunately, Andrée did not succeed, disregarding the forces of nature in the series of events that led to his death and those of his two companions…

Alfred Binet – How to Test Intelligence?

Tabea Tietz
On July 8, 1857, French psychologist Alfred Binet was born. He was a pioneer in the field of intelligence testing of the normal mind. He took a different approach than most psychologists of his day: he was interested in the workings of the normal mind. He invented the first practical intelligence test, the Binet-Simon scale rather than the pathology of mental illness. “Since we seek to know what is the physical phenomenon we perceive,…
