Water can boil and freeze simultaneously at its "triple point," a specific, low-pressure state (0.01°C at 611.657 pascals) where solid, liquid, and gas phases coexist in equilibrium. Under these precise vacuum conditions, water molecules with enough energy escape as vapor (boiling), while the rapid heat loss causes remaining molecules to freeze. @googlefactss#physics

On Pioneer 11 In December 1974 Pioneer 11 skimmed within 27.000 miles of Jupiters southern polar region. Observations in the infrared from Pioneer 10 a year earlier had already indicated that the planet was much brighter than would be the case had it merely been a planet reflecting light. D.A. Allen noted that Jupiter appeared so bright that it must be radiating more energy than it could absorb from the Sun. "When the long wavelength data are also included, we find that Jupiter radiates nearly three times the energy it receives." - D.A. Allen, Infrared: The New Astronomy (1975) This discovery should have been an earthquake in astronomy, but they kept being stubborn. With the right electrical input, Jupiter (the Sky Father) could light up in former glory. #physics @EuropeanTribalism

Thor still thunderous. (Current NASA footage.) Any more proof needed that the nature of the universe is electrical? Our ancient gods are still out there. It's crucial to understand mythology to accept this fact. #physics @EuropeanTribalism

On the mysterious handbags of the ancients Although I do not agree with the Thunderbolts people in every detail, they have great ideas and explanations for a lot of things. They recently released a video, explaining what the mysterious "Handbag of the Gods" might actually be. This handbag can be found all around the globe in ancient reliefs with no connecting culture. In short: it is a representation of an extreme electrical discharge event, seen as titanic storm. Watch the video! It also explains to some degree, why we see severe weather conditions and earthquakes. #physics#mythology https://www.youtube.com/watch?v=a8C2OdSbw84

On friar Georges Lemaitre Friar Georges Lemaitre, a Belgian priest and astrophysicist, published a paper in 1927 in the Annals of the Scientific Society of Brussel that first presented the idea of an expanding cosmos. In 1931, Lemaitre proposed what later became known as the 🔗Big Bang theory of the origin of the universe. The Catholic Church honoured Lemaitre's work: he was elected to the Pontificial Academy of Sciences (sic!) in 1936 and named prelate in 1960. By contrast, in 1948, astronomers in the atheist Soviet Union were urged to condemn the Big Bang as a reactionary theory helping clericalism, a hostility shared by many scientists and philosophers until the 1960s. Besides showing the compatibility of faith and science, the case of Lemaitre illustrates the way in which minds and cultures shaped by the belief that (the Abrahamic) God is a Trinity of reason and love have proved fruitful in perceiving order in the universe. Moreover, it is arguable that belief in (the Abrahamic) God who is beyond creation has freed us to theorise about the causation and change of the cosmos as a whole, rather than simply accepting the totality of material reality as an eternal, unchanging given. #physics#history @EuropeanTribalism

Mulugeta Bekele: the jailed and tortured scientist who kept #Ethiopian#physics alive Mulugeta Bekele paid a heavy price for remaining in #Ethiopia in the 1970s and 1980s. While many other academics had fled their homeland to avoid being targeted by its military rulers, Mulugeta did not. He stayed to teach #physics, almost single-handedly keeping it alive in the country. But Mulugeta was arrested and brutally tortured by members of the #Derg, Ethiopia’s ruling military junta. “I still have scars,” he says when we meet at his tiny, second-floor office at Addis Ababa University (AAU) in January 2026. Gentle and softly spoken, Mulugeta, 79, is formally retired but still active as a research physicist. In 2012 his efforts led to him being awarded the Sakharov prize by the American Physical Society (APS) “for his tireless efforts in defence of human rights and freedom of expression and education.... https://physicsworld.com/a/mulugeta-bekele-the-jailed-and-tortured-scientist-who-kept-ethiopian-physics-alive/
