"I see he always rights uppercase (no biggy computer users often do), but he writes the first letter in a larger capital than the rest. odd, what's that about?"
It's something that home dot matrix printers (at least the Star ones, I think also the Epson FX types) used to do in the 80s as one of their built-in fonts — you know, in plain text mode where you'd just send them ASCII and they'd put it on the page, left to right, top to bottom. It was a lot faster and easier to manage than actual graphics output, and sometimes got you better looking characters as the methods for getting into graphics mode weren't universal and sometimes having your printer support the popular ones (usually FX compatibility) left it rescaling (usually upscaling) graphics for print-out.
Anyway, I reckon either it's something with a typographical root somewhere or he just cribbed it from that. As a lab scientist I'm sure he dealt with enough dot matrix printouts in his day.
But seriously, who writes in uppercase?
