  • In my first year of university, we had a fun project to make us get used to physics. One of the projects required filming someone throwing a ball upwards, and then using the footage to get the maximum height the ball reached, and doing some simple calculations to get the initial velocity of the ball (if I recall correctly).

    One of the groups that chose that project was having a discussion on a problem they were facing: the ball was clearly moving upwards on one frame, but on the very next frame it was already moving downwards. You couldn’t get the exact apex from any specific frame.

    So one of the guys, bless his heart, gave a suggestion: “what if we played the (already filmed) video in slow motion… And then we filmed the video… And we put that one in slow motion as well? Maybe do that a couple of times?”

    A friend of mine was in that group and he still makes fun of that moment, to this day, over 10 years later. We were studying applied physics.

    A lot of people are replying as if OP asked a question. It’s a link to a blog post explaining why a kilobyte is 1000 and not 1024 bytes (exactly as the title says!). OP knows the answer, in fact they know it so well they wrote an extensive post about it.

    Thank you for the write up! You should re-check the spelling and grammar as some sections had some troubles. I have a sentence I need to go to the post to get, so let me edit this later!

    Edit: the second half of this sentence is a mess: “The factors don’t solely consist of twos, but ten are certainly lot of them.” Otherwise nothing jumped out at me but I would reread it just in case!
