Table salt is hygroscopic and may be deliquescent at high temperature and humidity. (Artem Beliaikin)
Deliquescence Definition Deliquescence refers to the property of a substance to absorb water from the air to dissolve itself and form an aqueous solution. Materials with this property are termed deliquescent. Deliquescent materials are a class of hygroscopic substances. Other types of hygroscopic materials may absorb water, yet not dissolve. In order to be deliquescent, […]

Data from Comet 67P/Churyumov-Gerasimenko or the Rosetta Comet tells us how a comet smells. ESA/Rosetta/MPS for OSIRIS Team
The Rosetta probe made incredible discoveries about comets by taking measurements of  67P/Churyumov-Gerasimenko. Its ROSINA instrument (Rosetta Orbiter Sensor for Ion and Neutral Analysis) included two mass spectrometers that determined how a comet smells. If you think it smells like a dirty snowball, guess again (unless you find that snowball at […]

Werner Heisenberg
December 5 is Werner Heisenberg’s birthday. Heisenberg was a German physicist who is best known for the uncertainty principle of quantum mechanics. The uncertainty principle is one of the main differences between the study of classical mechanics and quantum mechanics. In classical mechanics, a physical quantity can be simultaneously assigned […]

Luigi Galvani
December 4 marks the passing of Luigi Galvani. Galvani was an Italian physician who first identified electrical activity in living tissue. Towards the end of the 18th Century, one of the newest and cutting-edge scientific fields of study was electricity. Galvani acquired his own electrostatic machine to generate static electricity […]
