i see schematics with values such as .01uF among others... why out of all components are these not labeled using engineering notation
It is a matter of history, sadly. Capacitors where built well before the International System of measurement (SI) was established and some prefixes weren't used so much (e.g. nano).
For example, usually capacitors only used microfarad (sometimes written as \$MFD\$) and picofarad as units, this latter often written as micromicrofarad (\$\mu\mu F\$). Therefore \$10nF\$ could only be written as either \$10,000 pF\$ or \$0.01 \mu F\$.
Combine this with the need to encode other information on the smaller packages of the time (e.g. tolerance), and you end up with a metric ton of different encoding schemes, some more obscure than others.
Since old habits are hard to die, even in modern industry, the markings on the caps follow, in some way, the old tradition, where nanofarads "didn't exist".
The history of this is probably bound up in the technology of early capacitors. In the early days, capacitors were
- Electrolytic or oil-filled (generally larger than 1uF)
- Mica or NP0 (and other controlled tempco) ceramic types or air (some pF to hundreds of pF)
- Paper or film types, generally ranging from maybe 0.01uF to a few uF.
It probably seemed easier at the time for the engineers of old to use uF for all but RF applications, where pF were more appropriate.
