    In January 1783, Price returned to his laboratory in Guildford, ostensibly to start production of the miraculous powders. In fact, he set about the distillation of laurel water (which contained hydrogen cyanide, commonly known as prussic acid). He wrote his will at the same time, but it was another six months before he returned to London to invite members of the Royal Society to witness the experiment on 3 August in his laboratory in Guildford.

    Despite the claimed successes of his initial demonstrations and the furor they had caused, only three members turned up in Guildford on the appointed day. Although clearly disappointed by the poor turnout, Price welcomed the three men and then, stepping to one side, ended his life by drinking the flask of laurel water he had prepared. The three men immediately noticed a change in his appearance, but before they could do anything, Price had died of cyanide poisoning.





  • You keep saying that, but it’s not an extra step. Weighing the food is in place of the volume measurement, not in addition.

    Using volume measurement: start cutting broccoli. Add to a measuring cup until you get the right amount.

    Using weight measurement: cut broccoli. Add to scale until you have the right amount (actually I would usually weigh out a single large piece, then chop it all at once - same amount of effort).







  • Just a small note: the pressures in this chart are absolute, not gauge. In everyday usage (like talking about tire pressure) we mean gauge pressure - that is, the difference in pressure from atmospheric pressure.

    Your overall point is well taken (the change in temperature doesn’t matter much), but the numbers will be slightly different. For example, a tire filled to 100 psig (gauge) will reach 106.496 psig at 100 deg F, versus 105.663 in the original chart (assuming 14.7 psia atmospheric pressure).



  • Even better, here’s a direct link to a NASA page discussing the data: https://earthobservatory.nasa.gov/images/150192/tracking-30-years-of-sea-level-rise

    Some quotes from the page:

    Scientists have found that global mean sea level—shown in the line plot above and below—has risen 10.1 centimeters (3.98 inches) since 1992. Over the past 140 years, satellites and tide gauges together show that global sea level has risen 21 to 24 centimeters (8 to 9 inches).

    “With 30 years of data, we can finally see what a huge impact we have on the Earth’s climate,” said Josh Willis, an oceanographer at the Jet Propulsion Laboratory and NASA’s project scientist for Sentinel-6 Michael Freilich. “The rise of sea level caused by human interference with the climate now dwarfs the natural cycles. And it is happening faster and faster every decade.”

    The altimetry data also show that the rate of sea level rise is accelerating. Over the course of the 20th century, global mean sea level rose at about 1.5 millimeters per year. By the early 1990s, it was about 2.5 mm per year. Over the past decade, the rate has increased to 3.9 mm (0.15 inches) per year.

    While a few millimeters of sea level rise per year may seem small, scientists estimate that every 2.5 centimeters (1 inch) of sea level rise translates into 2.5 meters (8.5 feet) of beachfront lost along the average coast. It also means that high tides and storm surges can rise even higher, bringing more coastal flooding, even on sunny days. In a report issued in February 2022, U.S. scientists concluded that by 2050 sea level along U.S. coastlines could rise between 25 to 30 centimeters (10 to 12 inches) above today’s levels.
