ON BLACK HOLES AND BATHTUBS. “Black hole accretion can be compared with water swirling down a drain. Treating matter as a ripple in a field, the water can stand in for spacetime itself, or a field rippling with quantum activity. “We showed that waves moving in a draining bathtub push water down the plug hole, modifying significantly the drain speed and consequently changing the effective gravitational pull of the analogue black hole." https://lnkd.in/d5pVXXC View in LinkedIn

ATOMIC COMPOSITIONS. “Chemists of the 1830s and 40s were beginning to untangle the chemical composition of plant and animal products, and assign molecular formulas to what had previously been an undifferentiated sea of carbon and hydrogen.” https://www.tandfonline.com/doi/full/10.1080/00026980.2020.1867786 View in LinkedIn

OPTICAL PROPERTIES. “Laurent also used this work to recast the relationship between living and non-living substances, acknowledging that they were composed of the same constituent atoms, but focusing on differences in their arrangements.” https://lnkd.in/d5-aKnU View in LinkedIn

ALICE AND BOB are two of the most famous of physicists’ guinea pigs, and have been subjected to abject cruelty in hundreds of articles. These two poor souls have been teleported, turned upside down, inside out and pulled through the hedge backwards. All in the name of science. https://lnkd.in/dif7Y_D View in LinkedIn

DASHED DREAMS. “For Auguste Laurent in particular, his work on morphine and other intoxicating alkaloids was a turning point. He entered it optimistic about the prospects of artificially producing morphine, nicotine, and other organic compounds. He left it convinced that any such laboratory creations would never be able to have the same effects on the human body.” https://www.tandfonline.com/doi/full/10.1080/00026980.2020.1867786 View in LinkedIn

STRANGE MATTER HYPOTHESIS. “Under this hypothesis there should be strange matter in the universe: (1) Quark stars (often called "strange stars") consist of quark matter from their core to their surface. They would be several kilometers across, and may have a very thin crust of nuclear matter. (2) Strangelets are small pieces of strange matter, perhaps as small as nuclei. They would be produced when strange stars are formed or collide, or when a nucleus decays.” https://en.m.wikipedia.org/wiki/Strange_matter View in LinkedIn

STABILITY. “Strange matter that is stable at zero pressure. If the "strange matter hypothesis" is true then nuclear matter is metastable against decaying into strange matter. The lifetime for spontaneous decay is very long, so we do not see this decay process happening around us.” https://en.m.wikipedia.org/wiki/Strange_matter View in LinkedIn

TRANSITION TO QUARKS. “But a more precise estimate is not yet available, because the strong interaction that governs the behavior of quarks is mathematically intractable, and numerical calculations using lattice QCD are currently blocked by the fermion sign problem.” https://en.m.wikipedia.org/wiki/Strange_matter View in LinkedIn
