The CPU: From Conception to Birth
CrzyP writes "Most of us have seen flowcharts and heard lectures on how a CPU functions in a computer. What a lot of us do not know, however, is how a CPU is created. Sudhian describes the step-by-step process of how a CPU is made, from grains of sand to a wafer of circuits. Ahhh sand, the building block of life...in the tech world!"
Ok... so the article is not exactly new, nor interesting, so I'm gonna talk about something related :
DNA microarrays from Affymetrix, used to quantify gene expression, are built on a process inspired from CPU design (photolitography - read more about it here). Chips are getting more complex with time, ala Moore Law (shrinking the probe cells to get more density); the most recent human chip harbor 1 300 000 probes representing 39000 transcripts and variants.
So technology developed for CPU is helping to find cures for diseases, increase our knowledge of life... etc. Isn't cool?

I have often wondered about what exactly goes into the technology we take for granted.
The thought experiment I perform is to imagine what it would take to get the end product from absolutely nothing except the stuff around you found naturally. Working in the basement of the University of Washington physics laboratory, I often wondered how someone would build a milling machine or an industrial lathe. You can cut wood with rudimentary tools, and making crude iron or steel tools isn't too complicated, but how would construct a precise machine with all the guages and dials and electric motors and so on?
It sure brings me to a realization of just how far we have come from slogging about in mud and eating rats like we did in the dark ages. Our world is so complicated that no one person can understand more than a small fraction of it. Everyone is a specialist of one sort of another, even the garbage collectors and sewage system maintainers. Every generation of worker brings ingenuity to the job, and bit by bit their job becomes more and more complicated yet efficient.
Soon, will we each have a small chunk of humanity's experience in our skulls? Will we rule an insanely complicated world governed by machines and processes no one can fully understand? Or have we already come to that point?
The radical sect of Islam would either see you dead or "reverted" to Islam.
It's not a troll - that article was written at a 9th grade level at best. I read the whole thing looking for something interesting and there wasn't.
