My impression is that the vast majority of the garbage is actually quite small particles and fragments, not whole plastic bottles and the like that could be scooped up with nets. Would need some sort of high-volume filtration system.
it seemed like for a time "Micro" was really hot as a precursor to a company name.
The '80s was the height of the microcomputer revolution. For anyone who didn't live through it, a microcomputer is a computer which uses a microprocessor (a CPU on a single chip). This differentiates them from minicomputers and mainframes which, at the time, which typically had different parts of the CPU in several different chips. It wasn't until the mid '90s that even mainframes were using microprocessors; the first two generations of IBM's POWER series, for example, were multi-chip configurations.
The companies that rode the microcomputer wave were often not the companies that did well in the shrinking minicomputer and mainframe markets (and the minicomputer companies were often not established mainframe names either). They used micro- to differentiate themselves from the dinosaurs who were still clinging to the one-computer-per-company model. The implication was low-cost and flexible.
We have a equal opportunity Calculus class -- it's fully integrated.
