Reply to My grandpa's old watches. He got the left one for his 25th birthday in 1939 and the right one for his 50th birthday in 1964. Still running strong and frequently used by me. by denjohan

That's cool; I have the same certina from my grandad. Watch face just needed a polish. They go for like 600 bucks or so on the secondhand market in good order iirc

Reply to can someone explain the difference between quantum computing and classic computing in simpler words? how can quantum computing benefit us from a consumer perspective? by village_aapiser

Eli10: some problems get much harder when they get bigger. Rather than difficulty scaling linearl (eg, y=a*X), they can scale like a polynomial or exponential (eg y =a**X)

This rule isn't necessarily true for all problems on a quantum computer. You can have problems that take an exponential amount of time to solve on a classical computer, actually take a linear amount of time on a quantum one.
