    I like useless facts! :D

    Here’s another! The degree Celsius and degree Centigrade are technically two distinct temperature scales; the difference just only becomes noticeable at the resolution of thousandths!

          Eggs have a protective layer of wax that protects them from bacteria. However, in the US, this layer is removed, which means eggs need to be refrigerated there, while in most other countries they can be kept at room temperature for long periods of time without spoiling.

          Wait, maybe this isn’t useless…

            In ancient times, one of the timekeeping devices used in some places was the water clock, where a hole was put into the side of a water container, where the water dripped into another container, and the water level of the second container corresponded to certain times!

              Whales have their own form of language. Scientists have identified a number of patterns in whale calls that seem to suggest they have a similar system of communication to our own. Their calls have certain sequences called codas that seem to repeat reliably in their speech, and show similar properties to our human vowels.

              These aren’t just instinct either, they must be learned, and so baby whales will start out only being able to make incoherent sounds, until eventually they are taught to use the same codas their parents do.

              Not only that, but they are different for each pod, so two separate groups of whales can’t communicate with eachother because their languages are differerent.

              Scientists are currently trying to decipher whale language with the help of AI language models.

                  The most preserved dinosaur fossil ever is of a Psittacosaurus. This fossil is so well preserved in fact, that scientists were able see what it’s cloaca looked like.

                    For decades, the kilogram all around the world was calibrated to the Prototype Kilogram, a 1 kg physical cylinder housed in France. Over time, despite being kept in a vacuum-sealed case in a climate-controlled secure vault, it was found to actually be steadily losing mass due to normal degradation just from existing.

                    Nowadays, it’s no longer as much a concern due to the kilogram being formally defined relative to universal physical constants.
