 Nov 04, 2011, 12:21 AM Roll on Two ! Yea, 1+1=1, 0+0= 1 The + sign in boolean algebra is called Logical OR. say 1 = 5 volts, 0 = 0 volts. A two wire electronic OR gate with a 1+0 = 1, 0+1 = 1, 0+0 = 0 The 0+0 = 1 is an inverted input OR gate in which the output = 1 when either input is 0.
 Nov 04, 2011, 03:29 AM Registered User off topic: a while back, my algebra professor wrote on blackboard 2+2=X students were asked to complete the equation. All of them who answered "X=4", some 10%, failed. catch was in the sign +. It is a matter of agreement that we use sign + for addition but that sign can represent any operation conceivable. It can represent division for instance and then the right answer would be X=1. While looking at modern algebra books, my kids study from, I can only cry and sob. And give them my old books.

Now that's a good joke !
Being smart has nothing to do with not learning how to be content!

Actually the correct way to write the NOR equation is !(0+0)=1......the "!" meaning NOT or INVERSE. Then there is exclusive OR/NOR, conjunction/disjunction, etc. ......http://en.wikipedia.org/wiki/Boolean_algebra

Dry reading, but you'd be amazed by how useful it is........I can be 100% sure that whereever you are, reading this, there is something using it within arms length of you.......

Why in the world would you post that sign?” “Because,” the owner replied, “before I posted that sign, people kept tripping over him.”
Reminds me of the Peter Sellers sketch. (Apologies for a video in the jokes thread.)

Roll on Two !
After working thousands of gates, we knew the shorthand version. Ahhhh I remember that first mainframe job, crunching through 10 flipflops gated with 5 or 10 gates on each flipflop leg of the circuits. I accepted automated test equipment with full understanding. A human is not meant to do that. But I spent 2 years gate busting like that.

I was straining but able to keep up with that and 8085 machine code while working a day job on satellite navigation systems. USCLA extension classes. I rarely used it , soon after , mega memory and MIPS were suddenly common and I do think lots of people got lazy from not really needing it so badly. And then also compilers came around.
I'll bet it is mainly used by semiconductor engineers these days. Or relay engineers. And I'll bet there are boolean simplification programs available. Remember, it's intelligence is limited to that of the software engineer who wrote it.
Mathcad took away my pencil rage. I used to work math problems out all the time. I got started on some differential equations and was sidetracked by a Motoman obsession.

 Nov 06, 2011, 04:49 PM Its all fun Well I used to find jokes in this thread, but now it is full of nerdy jerks showing that they listened to the teacher rather than ogled the good sort sitting in the row in front. I guess that is itself a joke.
 Nov 06, 2011, 05:11 PM Danish? Don't U eat that?? These days if you need something to perform a task equal to a boolean system more complex than just a few tens of gates and/or F/F's either a PAL circuit or a tiny microcontroller is usually chosen. One PAL programming software i have worked with has both an automatic simplification routine per pushbuttom, and even some degree of automatic synthezisation based on the wanted input/output relation....... But just to do a somewhat scruffy attempt to try to get back on track: Why do mathematicians always confuse Halloween and Christmas? Because 31 Oct = 25 Dec EDIT: Ahhh, Tony has awaken......what took you so long? I'm surprized we were allowed to "nerd around" as long as we did.....
 Nov 06, 2011, 06:14 PM Roll on Two ! Ok , how about this Tony, I'm sure the whole world knows about the Power Ball lottery. But around here we have the Power Jaw. A 5 Hour Energy Booster and a pack of chewing tobacco. Speed Spit. Spit spit spit. Yuk ! I don't think I want a Power Jaw ticket. Last edited by Chophop; Nov 06, 2011 at 10:14 PM.
 Nov 06, 2011, 08:01 PM Don't look at me like that.... Two salesmen had to spend the night at an old mansion when their car broke down. The rich ole-lady that owned the place said she would have the auto fixed by her private mechanic by morning. She fed them a lavish meal cooked by her personal chef and had the maid take them to beautiful rooms for the night. The next morning they were back on the road again. Several months later, back at the office, one of the salesmen gets a call. he walks down the hall into his buddies office and ask " Hey, remember when we brokedown last fall ?" Buddy " Yea " " Did you sneak out of the room in the middle of the night ?" Buddy " Yea" " Did you go to the Rich old ladies room ? " Buddy " yea" " Did you make love to her ? " Buddy " Yea" " Did you give her MY name ? " Buddy " Yea" " Well, she just died and left me everything."
