    Those planet comparisons always hurt my brain. The scale is just too much to comprehend in my tiny brain.

    The Russians who have a history of left field thinking came up with the Setun, a bunch of ternary computers.


    More importantly there's six trits in a tryte

    Not really. It's just about how big your alphabet is. We have 10 digits in decimal, so you count 0-9 and then add one to the next digit, e.g.

    000
    001
    002
    003
    ...
    009
    010
    011
    012
    ...

    In binary, you just have an alphabet of 2, so you roll over every 2:

    000 = 0
    001 = 1
    010 = 2
    011 = 3
    100 = 4
    101 = 5
    110 = 6
    ...

    In trinary, you have an alphabet of 3.

    000 = 0
    001 = 1
    002 = 2
    010 = 3
    011 = 4
    012 = 5
    020 = 6
    021 = 7
    022 = 8
    100 = 9
    101 = 10
    ...

    Imagine you want to make a machine that stores and operates on numbers. How do you store a number? The solution a binary computer uses is that it has some stuff inside that can be in one of two 'positions' (which represent 0 or 1). It's magnetic, or it's about electrical charge, but that doesn't matter. You could just represent stuff with some coins. Heads for 0, tails for 1. Put a row of coins together, and you can represent bigger numbers like above.

    Modern tech is build around binary computer but there's no particular reason binary computers are better than decimal or trinary computers (binary is a bit simpler, so we got it to work well and then kept making better ones), and people have built all three kinds.

    Who died of getting wet.

    He got soaked walking three miles to a lecture one evening and, after giving the lecture in his wet clothes, caught cold. It turned to pneumonia, whereupon his wife, thinking a hair of the dog was the best cure, wrapped him up in a blanket and kept pouring more water on him. His condition went downhill and he died as a result.

    Strictly speaking he was murdered by his wife

    Manslaughter, at worst, as she wasn't carrying out a premeditated attempt to end his life?

    I don't know who that fella is but the effect is real. That said, it is still a matter of great debate and experiment in the scientific world as to how it happens and why the rate of freezing V temperature of the water does vary. The covalent bonding of Hydrogen at temperate, is thought to be a major factor.

    If you want to program in Binary you should use VHDL*


    It's got all nine values of 0 and 1.

    'U': uninitialized. This signal hasn't been set yet.
    'X': unknown. Impossible to determine this value/result.
    '0': logic 0
    '1': logic 1
    'Z': High Impedance
    'W': Weak signal, can't tell if it should be 0 or 1.
    'L': Weak signal that should probably go to 0
    'H': Weak signal that should probably go to 1
    '-': Don't care.


    *VHDL stands for VHSI** Hardware Description Language

    **VHSI stands for Very High Speed Integrated Circuit

    I prefer the explanation that cold water is more likely to be still so there's less movement to convey the heat.

    Like the experiment where when you use a weight to hold down an ice cube in a test tube of water you can boil the top with a Bunsen burner before the water melts.

    The front paws of the giant anteater, when seen from the side, look like the head of a giant panda in profile.
