Things of beauty

When you buy and use a USB thumb drive, as they’re called, do you wonder what’s inside that bit of plastic?

Above is a 1 megabit (approx.) Large Scale Integrated Circuit (LSIC) containg many individual memory chips to make up the 1 MB of Random Access Memory (RAM). Notice that it’s four rows of eight squares. We tend to think in terms of powers of two, and eight is a good number.

I find these images beautiful:


This one is the printed circuit board layout which holds the ICs and all the associated circuit components. Look at the beautiful complexity! Human hands did this. Computer software plays a bug part in laying it out, but a human wrote that software anyway.
