I want to learn alchemy?

Question

I want to learn alchemy?

Answer 1

You can turn lead into gold (in particle physics) but it takes a lot more energy than you'll ever recover by selling the gold.  It's not worth it.  

Maybe you should learn chemistry instead.

Answer 2

So you want to convert lead to gold, huh? People have been trying it for many hundreds of years, and no one has succeeded yet. You might start with searching for the Philosopher's Stone. Good luck!
