Sagebrush posted:bytes are an archaic concept anyway. we don't use 8-bit computers anymore so there's no particular reason to group data that way. everything should just be measured in bits. it's usually the smallest directly addressable unit, so it kinda makes sense

echinopsis posted:when we’re doing drug calculations regarding concentrations you need to specify if say 1% means volume in volume or weight in volume and if it’s weight in volume then 1% means 10mg/mL and 100% (if it was possible) would mean 1g/mL (or 1kg/L) the weight in volume thing is weird. normally if you're dealing with ratios the units should cancel out (like they do for the volume example). but now you've got two different units. in physics that's usually a sign you hosed up or whatever you're doing doesn't make sense must be something a pharmacist came up with while high on their own supply

Sagebrush posted:i am reminded of how marie curie was upset that the original value of the Curie, the unit for radioactive emission, would be defined by the radiation emitted by a infinitesimally small amount of radium (radium being extraordinarily radioactive). so she insisted that it be the amount of radiation emitted by one gram of radium instead, an extremely dangerous quantity, and because she was so famous they agreed. so we now commonly speak of fractions of microcuries, and if you ever see a whole Curie you're probably going to die apparently, at one point she came to north america and brought some of her samples with her. she visited a bunch of places including what was at the time the physics building at a local university (now the science library) to show off various experiments. that was in like the 1910s or 1920s. as might be expected safety precautions when dealing with radioactive stuff were rather lax back then, and in the 1950s someone eventually noticed that the basement of that building where the demonstrations happened still had a surprisingly high concentration of rather exotic and not-entirely-stable isotopes. the real mean stuff had already decayed by that point, but they still didn't take any chances and decontaminated the place
