A book I'd like to see:
How to build a radio transmitter completely from
scratch, starting with how to chip flint to make
the stone knife to skin an animal to make leather to use
for seals in the pump you'll build in order to evacuate
the vacuum tubes you'll blow from glass that started off
as sand; and how to figure out where to dig for copper
ore, tips on constructing tools with which to remove it
from the ground, and how to smelt it and draw the copper
into wire.
Does this book already exist? It'd be a fun read,
no? (Okay, so maybe being able to construct a functioning
time machine starting with raw materials in their natural
forms would make even more sense in terms of situations in
which you might actually need such a book, but ...)
I wonder whether there are any steps which would absolutely
require more than one person -- drawing the wire, perhaps?
And would any iron or steel need to be involved, or could
the entire project be accomplished with only wood, leather,
sinew, quartz, flint, copper, zinc, and water? (Obviously
some steps would be easier with steel tools, but
then we'd have to mine and smelt the iron ore, add coke,
etc.)

memory circuit using stone knives and bearskins."
