  • I found a reddit post why sodium and potassium have 2 names:

    There was some argument over what to call the elements. They were discovered by Sir Humphrey Davy who called them “sodium” from the Latin “sodanum” for a compound of sodium used as a treatment for headaches, and “potassium” from English “potash” which was the method used to extract potassium salts.

    But a German chemist, Ludwig Wilhelm Gilbert, proposed “natronium” from Neo-Latin as a reference to “natron” which is what the Egyptians called sodium carbonate, and “kalium” from the Neo-Latin of the Arabic “al qalyah” which means “ashes”.

    So in English they were “sodium” and “potassium”, but in German they were “Natronium” (now simply “Natrium”) and “Kalium”.

    It just so happened that the guy who invented the modern chemical symbols was Jöns Jacob Berzelius. He was Swiss and spoke German, so he derived the symbols from the German names.






  • Wrong title, it should be:

    A Map of the world showing where the local time zone is wrong more than half hours

    An hour is a human concept, we just divided the day to 24 parts, we could use whatever else division. Local time is correct only on the center longitude, which is a line with zero thickness.

    Also it’s clearly visible that France and Spain are in the wrong time zone, and it was changed by the Nazis. Before WW2 France and Spain was in the same zone as Britain. France changed because of the German occupation, and they forgot to change back after the war.













  • Why do you care? People do a lot of stupid and wrong things, you don’t have to care or share these things. See my example: I read about this backround image app or whatever is this, I thought “yeah, it’s stupid and I don’t care” and moved on with my life. Never thought about this again until you posted this here. There are a lot more important things to be angry about. Ignore the unnecessary. This guy makes nicely edited reviews, that’s all, forget the extra bullshit around that. Your life will be better.
