42.7 grams of Cu represents how many kilograms?

Well, how many grams in 1 kilogram?

Google "SI measurements" if you're unsure.

Since when is smart defined as "able to divide by 1000" ?

Actually, I guess it depends on what you mean by "represents". Here in the UK about 9.5 g of some brassy alloy represents a pound.

I think the question refers to the fact that, seeing that title, we all want to prove just how smart we are so we answer a question that might otherwise seem too trivial to bother with.

lol I know it's right there. KILOgram. I think the smart part comes from relating this to relativity.

well, if you knew the velocity of the copper wrt to the observers frame you could work out the relativistic mass of the coper assuming the 42.7g is the rest mass. or something.

Maybe the concept of "beeing smart" is relative.

It seems no matter how much we learn, the number of unanswered questions seems constant. Why is that?

Actually, the more we learn, the greater the number of unanswered questions, because our knowledge shows us new and more specific directions of inquiry. Without any knowledge, the only question you can ask is, "whu..?" It's not really that mysterious a process...

Are they constant? Or increasing.

Yes it's not mysterious, I was mainly trying to be a little funny
