Mac and Barney discuss with some degree of trepidation
the alarmingly increasing rate at which new

Photodiodes and phototransistors were relatively
new on the electronics scene in 1969 when this article appeared in Electronics World
magazine. Prior to semiconductor light detectors, vacuum phototubes did the job in cameras,

(especially with medical equipment), inconvenience, and high cost. What we take for granted

than computers - a field sometimes referred to as
neuromorphic computing - have promised a new era of powerful computing.
While this all seems promising, one of the big shortcomings in neuromorphic computing
has been that it doesn't mimic the brain in a very important way. In the brain, for every
neuron there are a thousand synapses - the electrical signal sent between the neurons
of the brain. This poses a problem because a transistor ..."
