An another thing....

I don't think I'm shallow....I'm just very focus-minded.

Fibonacci... ugh. SEquences and Series were my least favorite!

OK. Here' goes.

The Fibonacci series had something to do with rabbits.. and their breeding habits. I don't remember the exact situation, but I can find it.

Anyway... the Fibonacci series is the sequence of numbers such that each new number in the series is the sum of the two numbers before it. You have to start out with the first 2 being given though - so the series is:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc.

Notice that 0+1=1, 1+1=2, 1+2=3, 2+3=5, 3+5=13, 5+13=18, etc.

The golden mean comes in because that's what the series of the ratios of consecutive numbers converges to... so the sequence 1/1, 2/1. 3/2, 5/3, 13/5, 18/13, etc. eventually converges to the golden mena. Don't remember what that value is... but I bet I can find out.

The golden mean is a ratio that comes into play in much of the natural world... harmonics in music are separated by it in some way, and the greeks liked to use it in their architecture. I do recall that the golden mean is one that satisfies the following situation:

Start out with a rectangle. Let the length of the long edge be L and the length of the short edge be S (yes... for "L"ong and "S"hort). Then let M = L/S (that is, we'll define the value "M" to be the ratio of the long side to the short side). So... If you set your rectangle up right, then if you cut off a portion of the rectangle that is SxS, then what's left over will now be a rectangle that has the dimensions S by (L-S). Helps if you draw a picture... cut a perfect square off of the end of the rectangle and look at what's left over.

Then we now have a new ratio M' = S/(L-S).

It's possible to set it up so that M = M'... this means that even if you keep cutting off squares, the ratio of the long side to the short side always stays the same. There's only one way to do this so it works... and it just happens that the ratio is... you guessed it... the golden mean.

Do I pass yet... or am I going to have to dig out my math books?

Also had someting to do with ferns, and I think the fibonacci series underlies a lot of fractal mathematics.

Rev wun't kiddin when he said you were the scholar type. Fibonnaci? Dang...the only thing I know about Fibbo is that it's a type of alert on my cell phone...

I never meant to call you a nerd...my apologies.

Just wanted to say that you were quite knowledgeable.
Don't worry Pac... I called me a nerd. Nobody who does math for living can claim to be anything EXCEPT a nerd. They might be well-adjusted, subtle nerds... bet they're still nerds. I'm proud of my nerditage.

Oh...ok. I beg to differ, but that's just me.


No damn wonder Rev is one smart cookie. Hard to get one by that ol' biscuit...

Okay...Now that we've verified Mrs.Revlis as an actual person, and not a character played by Rev...

Who can describe the process of nuclear fission and descride the neutron lifecycle within that process? And just what the hell is a "decay constant" anyway?

I had to learn that crap 20 years ago when I joined the Navy, but I've forgotten most of it. It was cool stuff, but holy crap was it hard to learn.

Well, I could describe to you the construction and materials involved in a modern Thermonuclear Weapon...  Does that count?

OK DEcay Constant AKA Halflife? Its a measure of the rate of decay for any given Radioactive bit of shid. Basically any radioactive material breaks down "Decays" at a set rate regardless of "Normal" outside influences. (Atomic Clock) Halflife is the measure of the amount of time it takes for 1/2 a given sample's nuclei to undergo decay and spit out a nuetron? It's a function of halves... From the original state you get 1/2, 1/4, 1/8,...? Something like that?

OK here you go... Web Smarts...

OK a real quick down and dirty Rev's explanation of Fission VS Fusion?

Fission, is the breaking apart of radioactive Nuclei to release a shid ton of energy. Basically you get the right amount of the right material together and one Nuetron rockets out of a nuclie and slams into another busting out another nuclei etc etc... Creating a ton of energy and a crap load of radio activity. Think fat man and Little boy. Basically there is a critical mass X. At this mass your refined fissionable will spontaneously and violently react, blowing apart billions and billions of nuclei scattering nuetrons everywhere and boom nuclear bomb...

Fusion reaction? OK the opposite of fission almost. Here you are forcing two hydrogen atoms together creating a helium atom and A SH!T ton of energy. Einstien worked this one out. Mass to energy conversions= HUGE amounts of energy. E=MC2 or Energy equals Mass times the speed of light... A thermo Nuclear weapon, is actually two bombs. A small Fission reaction used to kickstart a fussion reaction that realeases even more energy... basically the power of the sun, harnessed...
