When I was in college (the 1st time), there was a small poster on the wall detailing an equation... The equation was then written a different way, but was still equal to the first.. Then written a different way again, etc... Eventually the first equation and the last equation were NOT equal even though all equations "next" to each other balanced. Do any of you guys know what I'm referring to? It would be fun to have a copy of that.

There resides a man within the Ov'r 35 misc who knows that 2 + 2 = 5 for extremely large values of two, who I'm hoping will reveal the mechanics of this special mystery. :)

Have no idea what you're trying to recall, but it's a given that almost any formulation, when the order is changed, will result in a different "ending", whatever that might be. But lol, I know that you know this. Just trying to recall the poster for ....old times sake?

I'll leave it as an exercise to the reader to figure out why this doesn't work :)

Usually these are a simple issue of order of operations or rounding. Here is one we were shown in school

1/3 = 0.33333

1/3 + 1/3 + 1/3 = 1

0.33333 + 0.33333 + 0.33333 = 0.99999 /= 1

This might turn into a fun thrad. I have to run, but will ck back later for kewl maths or random pics of boobs if all else fails. :)

Because you can't divide by zero. (A-B)=0

(Going from line 4 to line 5)

I'm far from a math whiz, but it's simple to find where that series of equations breaks down. Line 4 does not lead into line 5.

As stated, division by 0 makes anything meaningless. That thing starts breaking down at line 3 which says that 0=0. From that point, meaningful mathematical operations cease.

As long as a person "feels" that 2=1, the argument is over.

It's definitely in that line from 4 to 5 - that doesn't work out properly and the equation breaks down as soon as you substitute any whole number in, whether it is zero or 100. Not sure about what rule it is breaking though.

Could not possibly disagree more. Having said that...and to be totally candid....I think Brian was a brilliant replacement for someone who couldn't be.....replaced.

And if you want to see/hear power, go back and listen to their first few albums; they are raw as hell, and they rock hard. Simple, Mel Bay chords.....all done with elan...unlike anyone else playing such simple chords. This is the essence of AC/DC. I saw them for the first (and only) time one year after this clip I posted (with Scott). Honestly, it becomes a "Ford vs Chevy" argument, and at the end of it all....I like most of their works, period. :)

By personality I'm saying more in the humor side of his lyrics and delivery, vs. Johnson being more direct. To me the Scott era was more rock-n-roll, heavy yes, but the Johnson era was more on the heavier, metal end of the spectrum. And yeah, both are great. Ford FTW! :)

Ford FTW! :)

Not entirely true... The two sided limit does not converge but it has two single sided limits, -infty and +infty depending on the direction of approach. From the positive direction, the limit is in fact infinity.

From the positive direction, the limit is in fact infinity.While you are absolutely correct about the one-sided limits (well done, btw!), the notation clearly indicates a two-sided limit. :)

Yep.

I've spent hours fretting over the agonizing details of mathematical notations but for me it's ultimately always been tied back to explaining a physical phenomenon. If one understands the physical interpretation, say, in this case as a graphical representation of 1/(x-8), the problems with the notation sort themselves out naturally. The limit, as it was written, had no reasonable physical interpretation. That's when you have to go back and ask "are these really the droids you're looking for?"

Ah, an engineer. :) Would you believe that the vast majority of mathematics has no physical interpretation and likely never will?

This is the formula for divorce.

the 1 is what is left due to irreconsilable differences, cause by events that occurred in line 4

or is this a formula for same sex marriage?

It only becomes relevant when a physicist or engineer finds an application for it. Physical interpretation was the example I stated above, explaining or approximating a physical phenomenon (or process) was the requirement; two different things.

edit: I've been at this game a long time. I'm inclined to believe most anything.
