This is for anyone even just made up plausible ideas as well.
These may seem like a strange questions but I don't know who to ask. The internet hasn't really been able to answer them for me.
If a computer whiz from 2015 who knew how to build and program computers I'm talking Reed Richards type intellect here. If he traveled to the 1950s and was stuck there and had just a laptop or I-pad with him.
What kind of computer could he build back then?
How big would it have to be?
What kind of things could he use it for? Practical applications etc.
I've found pictures online and the Computers from the 50s were as big as a bus.
Could he make something much smaller with 50s parts?
Could he do Wi-Fi?
Could make an internet?
Could he make cellular tech to give to people and talk remotely?
Would he have to make a tower or satellite to do it?
I'm not really talking about realistically, just possible or probable. I have specific ideas for this and would appreciate any feedback. I just want something that sounds plausible.
