     If the physical universe is endless then everything exists Even an anthropomorphic dog smoking a pipe. If I can imagine it, it exists.

   Today is the 65th anniversary of LEGO’s 1958 patent on their bricks in Denmark. Their very first bricks were introduced earlier than that, in 1949.

   But did you know that Chicago’s ELGO Plastics manufactured and sold their own interlocking plastic building blocks in the late 1930s, a full *ten years* before LEGO had the idea?

     @mcnees I played with a big round tub of these bricks as a kid—thanks to my mom’s yard sale expertise. They came with a booklet of different structures one could build, and I was able to come close to making a lot of them (only limited because the set was missing several pieces, the drawback of its coming from a yard sale).

    Seeing that @simsa04 is facing a potential housing crisis, I think I should update on the situation with my family in #SoCal.
    
    Mom is still in need of care, but my sister has to work full-time and then help out after work. Thus, she’s too tired to do much looking—either for another school district to work in, or for another home to live in. Prices are still too high for her income. The landlords have given us an undetermined amount of time to find a replacement.
    
    In the US, it is common to require every adult in the household to sign the lease. Mom refuses to leave the area, despite it being too costly to remain.

    Someone asked me to recommend some ABBA songs, and I realized that they were part of the background music of those years, but hardly ever did I specifically seek out their songs (other than Waterloo and Fernando and S.O.S.) … I couldn’t give them a real answer, since I only know their most popular hits.
    
    Ever noticed that once you start digging into a group’s music 🎶, you start to favor one of their least popular songs?

    Albert Einstein gave a famous lecture titled "Geometry and Experience" #OTD in 1921, for the Prussian Academy's Leibniz Day.

    He proposed that the question "Is the Universe spatially finite?" might be answered conclusively via measurement.

      The lecture set a course for philosophers and scientists gathered under the tent of logical empiricism. Via a system of "practically rigid rods" and "perfect clocks," it asserted that the character of spacetime could be determined empirically, as a matter of "practical geometry."

      This is pretty much the conceptual basis for most experiments that test the predictions of general relativity.

      @mcnees as a non-physicist I made the mistake of trying to read the lecture without the requisite background 😁

      lecture is here if anyone wants to dive into the subject:

    A short thread on Emmy Noether and giving credit.

    Felix Klein gave a lecture at the Mathematical Society of Göttingen #OTD in 1918. The title was “On Hilbert’s first note on the foundations of physics."

    Klein included excerpts from letters in which he and Hilbert give priority to Emmy Noether for her results on conservation of energy in general relativity.

      @cstross Plenty of data points already, but it’s a conjecture that, unfortunately, we probably won’t have to wait very long to test.
