why isn't quark used as a supercomputer for the large hadron collider program to understand the behaviour of the quark particles?
Same with gold. Humanity uses enormous amount of energy to mine a metal that doesn't do anything...we just sit on it...or in best case use for exchange.
...but due to its nature of being a highly efficient conductor it is also used in electronics and computers.
Yes, but thats only the case because gold is highly malleable... meaning you can create extremely thin layers of gold...
if that weren't the case, nobody would care to use gold as an efficient conductor, because it would cost a lot of money...
but since you can create gold leafs of only a few atoms (!) thickness, you can easily cover anything with gold.
Most famous example:

lol, try and do that with quark, and you get something like:

Sorry, quark, but gold wins.
