I would say its on-topic because someone might be musing whether they could build anything like a modern PC board themselves (no). Here's one company that makes
10 layer motherboards Here's an article on the guts of a typical PC mentioning 4 to 7 or more layers
Just think of the microwave frequency considerations & the complexity of routing traces in a multilayer board. Yow.
That's a frame relay or frational T1 or other leased line? Phone modem communication is much worse, especially for bursty 2-way. For a nice long file transfer then the phone modem is much like those services.
X11 over a 28-56k modem is usually murder - the simplest programs can generate megabytes of traffic. Over a 400kbit DSL, it's bearable, but still sluggish.
Or, just for geeky fun, could say that the 8080 evolved into the 8088 / 8086 -> 80186 -> 80286 -> 80386 -> 80486 -> Pentium
Then you'd come back and point out the Z80 also had 16 and 32 bit progeny.
I used to do Z80 assembler on the TRS-80, the Basic II wasn't very interesting. My Z80 assembler's manual has become so brown and brittle I'm afraid to open it.
that man's activities have had little or no effect on the climate of the earth, and the fossil record *proves* the average temperature of the earth has been much higher and much lower in the past, that the size and shape of ozone hole is purely due to solar cycles, and insolation is the key to climate?
maybe my radio....but the ignition system? Pretty well shielded, actually. And the components of the radio will short and toast keeping the pulse from the rest of the systems. A lightning bolt once struct the street in front of my house about 6 feet from my car. That's likely several pulses of well over 500 amperes at over half a billion volts...plenty of magnetic and electric field strength there. It made a scorch mark on pavement. My car and everyone elses still started; no damage to any electrical system.
Naw, anyone can make a coil of large gauge wire and a fast switched capacitor bank to make a high amperage pulse through it.....the question is, will it really be effective at damaging electronic equipment at a hundred yards or more away on a consistent basis? And even if it did, what if that equipment was in rugged military chassis, or more usually inside tank, armored transport, ship, concrete (with rebar) bunker, etc.
I can only conclude the military has tried this stuff & found it not up to promise.
Of course, English is not the most widely spoken language in the world...1. Chinese 2. Spanish...see the top ten here
Latin still lives on in medicine & biology, and the Roman Catholic Church, among other places.

If this was the case, one would just use a two dimensional vector
Of course, a complex number is a two dimensional vector.
The coordinates on a map provide a real world example, which was my point.
I can give definitions of multiplication and addition in my latitude and longitude example that result in a vector space.
The solutions we care about deal with real values.
oh no, if you study the physical sciences in even a rudimentary manner, you will find there are measurable quanties in the real world which are represented by complex numbers. For example, in an electrical circuit, the resistance has a pure real component, and the reactance an imaginary one (inductance positive and capacitance a negative imaginary value), and the impedance is the magnitude of that complex number. These can be measured!
There are numerous other such cases in fluid dynamics, mechanics, quantum theory. In fact, in advanced treatments in these fields, sometimes even higher order tuple vectors have use in the real world

Your statement about "abstract two dimensional objects" actually hints that it's not hard to give complex numbers a real physical meaning to explain them to someone...for exmaple, real numbers could be longitude, and imaginary latitude, then a point on a map could be a complex number.
Though I don't know why anyone would put a laptop that close to their crotch. I kept mine close to my knees and to the left so the exhaust port (on my former company's T20) dumped heat far from me. No Rocky Mountain Oysters served on my train, thanks.

Yes, they do have cameras that can function in space...maybe some can be modified to this purpose. But the idea that a web cam & atx motherboard, or just any old camera can be tossed out as some posters have suggested is silly. More conventional cameras have been used inside the climate controlled environment of spacecraft and space stations, but outside it's brutal.
It's space alright. Anything deployed outside far enough to have a field of view of the whole shuttle will certainly have small rotational and translational components in relation to the shuttle. The camera will even be in a different orbit, and will drift from the shuttle for that reason alone if no other. The human eye will not be able to detect that in a few seconds time frame while deploying, but over a minute or two it will be there.

we were speaking of non-nuclear EMP devices in this thread, speculating that perhaps they've been tried and found to be overrated.

You could each wear a 4 lbs. chunk of pu-239...when you get close there will be a pretty blue glow.
