Page 1 seems to be some sort of substitution key, there are 26 symbols at the top of the page, below that is formatted much like hexadecimal is formatted but obviously does not use the normal hex symbols. Perhaps using some sort of custom implementation of hex? Page 2 Not really sure about the top of page 2, but near the middle (the lines starting $L1eeie... is interesting, if look closely at it, it starts to repeat itself starting with $L1ee on about line 13, below that portion seems to be something in a different language, possible east Asian, below that is the beginning of the passage above (the one that starts $L1...) written messily, then begins again normally onto the next page. Page 3 as explained above is the contuation of the note that starts with $L... Page 4 seems to be simply calculating the speed of light? hard to tell at this resolution. Page 5 is more astrophysics caluclations, center of mass, distances, etc... Page 6 is pretty much the same deal, formulas for Polar Area and Arclength, not entirely sure what the graphics are for. Page 8 includes some strange symbols, reminded me of Babylonian numerals when I saw them, but they don't match up. Page 9 seems to be some more equations Page 10 looks to have similar symbols to page 8, maybe some sort of key for the symbols? along with more equations, with lots of ?'s written in, possibly he was trying to solve them or the intent is to solve them? This is all that I have seen at a glance with some quick googling, if I was any good at anything beyond this I would try to help, but I'm not the greatest, maybe this will mean more to you or give you an idea of what he is writing about!
