Millman's theorem
Thevenin's Theorem simplifies complex circuits into a single voltage source and series resistance. This allows analysis of load lines and operating points.
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
Integrated circuits consume less power, are smaller, can be more complex in a much smaller space and are cheaper to make for similar functions than vacuum tubes.
In point of fact, vacuum tubes do obey Ohm's law. Everything electrical obeys Ohm's law. The reason vacuum tubes don't appear to obey the law is that not every consideration takes into account the fact that vacuum tubs have dynamicresistance. Ohm's law, as applied to "pure" ohmic resistors, requires constant resistance, which no material, no matter how good, exhibits. In the real world, you have to consider that resistance can vary along with voltage and current, and this "complicates" things.

red lights, lasers, vacuum tubes, some TV tubes, etc.
Vacuum tubes were used back in the 19th century and mid-20th century for a number of things. At first they were used just in scientific areas, but then they were used as electronic amplifiers. They were eventually used in the first computers.
No, he had to use mechanical gears, etc. because they were the only device technology available in his time. Electric relays were first developed about 15 years after he designed his computer, while vacuum tubes were first developed about 90 years after he designed his computer.
Vacuum tubes are electronic devices that control the flow of electrons in a vacuum. They were widely used in early computer and radio technology before being replaced by transistors. Vacuum tubes can amplify signals and are known for their warm, vintage sound in audio equipment.
They are devices that are used to control the flow of current.
