At 0:39 Ahhhhh! I have math Dyslexia, in spite of loving Astronomy and Physics, takes me a hundred times more effort than the average person to try and understand anything with numbers, but eventually, I get it. Putting your post on hold until I have a few hours free of worries to study it. [spoiler]My worse nightmare when building computers... volts, rails, clocks, speeds, overclocking, scales, numbers everywhere! but it all works out in the end. While trying to spell out an email or code or password, I'm often heard saying "the letter 7 and the number C..." Yeah, I should stick with finger painting...[/spoiler]
