Re: Logic gatesHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130307 03:17:33
Re: Logic gatesWhich mathematical operations? The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #4 20130308 01:31:30
Re: Logic gatesI was trying to memorize and explain the logic gates earlier and i thought of sets.if U={1,0} and 1={{ }},0={ } and A AND B=A intersection B,A OR B=A union B,NOT A=A' then the idea seems to work.are these expressions valid? There are 10 kinds of people in the world,people who understand binary and people who don't. #5 20130322 01:18:58
Re: Logic gatesIf you wire the output of a logic gate to an input upstream from a bunch of logic gates, you create a sequential sort of circuit, depending what exactly you do. igloo myrtilles fourmis
