The castaway frequently finds on the beach bottles that have one-sentence messages on the inside, such as "There is fresh water in the next cove," "The British are coming to Concord," or "Lead melts at 330 degrees." A group of scientists lives on the island, and they separate these messages into two categories: empirical facts and analytic ...
The effect Leidenfrost described is a phenomenon in which a liquid, in near contact with a mass significantly hotter than its boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly. It is most commonly seen when cooking; one sprinkles drops of water in a skillet to gauge its temperature.
The Bezold–Brücke shift or luminance-on-hue effect [1] is a change in hue perception as light intensity changes. As intensity increases, spectral colors shift more towards blue (if below 500 nm) or yellow (if above 500 nm).

Edward Wheeler Scripture recounted this conclusion in The New Psychology (1897): "a live frog can actually be boiled without a movement if the water is heated slowly enough; in one experiment the temperature was raised at a rate of 0.002°C per second, and the frog was found dead at the end of 2½ hours without having moved." [27]
The dress was a 2015 online viral phenomenon centred on a photograph of a dress. Viewers disagreed on whether the dress was blue and black, or white and gold. The phenomenon revealed differences in human colour perception and became the subject of scientific investigations into neuroscience and vision science.
Bumping is a phenomenon in chemistry where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. In extreme cases, the container may be broken.
Boilover onset mechanism. The extreme violence of boilovers is due to the expansion of water from liquid to steam, which is by a factor of 1500 or more. [3] In practical storage scenarios, the presence of water under the burning fluid is sometimes due to spurious accumulation during plant operation (e.g., rainwater entering a seam in the tank roof, off-specification products from the source ...
