Scorpions absorb invisible UV light and re-emit it as visible neon blue. Fun fact: notice how the babies on her back don't glow yet, That's because their outer shells haven't hardened yet.

#KarenRead How are content creators other than the blogger charged with 18 + crimes related to witness intimidation contributing to the harassment of the witnesses? Two examples: On the left we have a content creator who tells her audience she presents the case as "fact" based from "court records" and yet we hear as recently as the latest episode an opinion not rooted in fact about Colin Albert. She states he has a temper and tendency to fight and yet nothing was presented at trial to establish this. No police reports of fights, no testimony with first hand experience that Colin was rage filled. Not a thing save two social media posts presented during his cross examination which could be interpreted as nothing more than typical teenage bravado. And yet because she consistently repeats she is objective & fact based, there is a possibility her audience will be misled into thinking her opinion is established fact, not gossip or speculation. On the right we have another content creator who allowed two prominent FKR "movement" Canton residents to present gossip and innuendo about Colin as fact. Neither one of these women had a single bit of evidence to support their libel. No police reports. No specific, verifiable incidents. Nothing. And yet Brian broadcast this gossip with no fact checking or pushback as to its veracity. What has happened to these witnesses is shameful and so many content creators swooped in and sought financial gain by participating in it. Subtle and overt have no difference when it is destroying an innocent person's life. Someday we will collectively look back and realize this.

When a nuclear reactor is switched on for the first time, an intense, almost hypnotic blue glow appears in the water surrounding the reactor core. This light is neither fire nor heat; it is Cherenkov radiation, a physical phenomenon that occurs when charged particles, such as high-energy electrons produced during nuclear fission, travel through a transparent medium faster than light can propagate within that same medium. While nothing can exceed the speed of light in a vacuum, light travels more slowly in materials like water. When a charged particle surpasses this reduced speed, it emits a coherent shock-like electromagnetic wave, often described as an optical analogue of a sonic boom. This radiation produces the distinctive blue glow. The colour arises because Cherenkov radiation is strongest at shorter wavelengths, which are dominated by blue and ultraviolet light. The phenomenon was first observed experimentally in 1934 and later explained theoretically, work that led to the Nobel Prize in Physics in 1958. Its explanation confirmed how relativity and electromagnetism operate in material media. Today, this deep blue light is both a warning and a scientific tool. It signals the presence of intense ionising radiation, while also being exploited in particle detectors, nuclear reactors, and neutrino observatories. It provides a rare, visible manifestation of subatomic processes that are otherwise hidden from direct human perception. #GottaLovePhysics #Physics
