My notes don’t include what triggered the thought, but I think it was something in one of the Lee Smolin books I read recently. My recent post, Analog Computing, brought the idea to mind again, because analog computers often use op amps. I was reminded yet again while reading about SPADs.
I’m talking about the very useful rules of thumb (heuristics) I learned to help understand, even design, electronic circuitry. They’re shortcuts in the sense of being only approximately true, but their simplified view can make a circuit much easier to understand.
I thought I’d pass them on for those interested in electronic design.
I think this may be the most (unintentionally) hysterical thing I’ve seen in a good long time (oh, the world of the future):
I mean seriously side-splitting, tears streaming down the face, really truly, delightfully, must-see funny. (I love the wrist device! Dick Tracy has come true in that regard. And just imagine: portable televisions!)
If it hasn’t been apparent, I’ve been giving a bit of a fall semester in some computer science basics. If it seems complicated, well, the truth is all we’ve done is peek in some windows. From a safe distance. And most of the blinds were down.
I thought we’d finish (yes, finish!) with a bang and take a deep dive down into the lowest levels of a computer, both on the engineering side and on the abstract logic side. When they say, “It’s all ones and zeros,” these are the bits (in both senses!) they mean.
Attention: You need to be at least this ━▇━ geeky for this ride!
The computer what? Connectome. The computer’s wiring diagram. The road map of how all the parts are connected.
Okay, granted, the term, connectome, usually applies to the neural wiring of a biological organism’s brain, particularly to the human brain. But the whole point of this series of posts is to compare a human brain with a computer so that we can think about how we might implement a human mind with a computer. As such, “connectome” seems apropos.
Today we’ll try to figure out what’s involved in modeling one in software.
