The new paradoxes of quantum physics

Warning to the reader. What will follow can surprise, disturb, shock, to the point of making doubt of having read correctly. However, the characters are real, the experiences validated by the scientific community and reproduced. But “don’t try this at home,” as wrestling broadcasts warn. The use of the concepts, conclusions, reflections reported here must … Read more

Physics professor’s teaching skills led to significant research contracts for CU Boulder

Before the first federal lab came to Boulder, Professor William B. Pietenpol was quietly moving scientific research at the University of Colorado Boulder into the big time. Pietentol, who was born in Iowa and earned his Ph.D. at the University of Wisconsin, was hired as assistant physics professor at CU in 1920. By 1935 he … Read more

Nobel Prize 2021 in Physics. For models of conditioning climate change and complex phenomena

The three winners will share this year’s Nobel Prize in Physics for research into climate and chaotic and apparently random phenomena. Earth physicists Syukuro Manabe of Princeton University (USA) and Klaus Hasselmann (Max Planck Climate Institute in Hamburg) were identified as the winners who laid the foundations for the latest knowledge about our planet’s climate … Read more

A seismometer maps Mars’s anatomy: Physics Today: Vol 74, No 10

On 26 November 2018, the InSight lander—whose acronym stands for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport—touched down on Mars’s Elysium Planitia. Within two months on that flat, volcanic plain, the lander’s robotic arm removed a seismometer from the lander deck and placed it on the ground (figure 1), where it started listening … Read more

Solved Paradox in Solar Physics That Lasted Two Decades

In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been discovered during the analysis of the polarization of sunlight, implies that the solar chromosphere (an important layer of the solar atmosphere) is virtually unmagnetized, in sharp contradiction with common wisdom. This paradox motivated laboratory experiments and theoretical investigations … Read more

The Quest to Build a Functional, Energy-Efficient Refrigerator That Works in Space | Innovation

So much of our everyday lives relies on gravity. We jump, toss a ball, pour ourselves a drink and experience rain, all thanks to the natural force. Still, it’s easy to forget that even a household appliance like a refrigerator needs gravity to work. A fridge siphons heat from its frigid insides and dumps it … Read more
