Also, the classic essay "I, Pencil"

> I am a lead pencil—the ordinary wooden pencil familiar to all boys and girls and adults who can read and write.*

Writing is both my vocation and my avocation; that's all I do.

You may wonder why I should write a genealogy.

"Charcoal has to be chopped to a specific size for the operation to run smoothly. I chopped mine during the days before the run in little chunks about a cubic inch or less." Chopped using what?

I think he's trying to make a knife from scratch, not make a knife only using stone-age technology.

This is amazing (still) but hasn't it been on here before? I remember reading through it ages ago.

I might be wrong (search turns up nothing), I have seen this before though and thought it came from here (since this is usually where I find my quality reading material).

No need to get all downvotey, I wish I had the authors abilities.

Hey, I get it and I think it's actually a neat project. But "from scratch" is an entirely meaningless phrase.

I sometimes wonder how long would it take for the civilization to re-create the current level of technology, if all the material artifacts disappear one day: books, computers, robots, factories, even hammers. If all that remains is the current level of knowledge in the heads of 7bln people, how long would it take from the stone age to Core i7, heart transplants and Boeing 787s? And how much different the world would be if we had to re-create this from scratch without the legacy of previous technological generations?

It's reasons like this, that I really wonder if someone from today were to time travel into the past if anything they know would be useful at all. Medieval people would probably think we're all idiots.

An average person would not be overly useful, but a skilled and knowledgeable individual would have much to offer. A chemist can make nylon, gunpowder, matches, or plastic from relatively easily obtained chemicals even in ancient times, for example. There are also lots of other little tricks that are just as or more valuable. Things like germ theory, medicine, cooking, electricity, etc. In roman times it would have b…

The idea of science itself would probably be more powerful than anything an individual could accomplish. Let a 1000 flowers bloom and all that.

A question I've had about this is where are the ready supplies of materials that could be used in the recreation? Could we spread across the hills and still find iron and copper deposits? Aren't these all played out by now? We would need to shift to another economic base from new materials I think rather than recreate what we had before, because that's gone.
