Simplish maths question

[Karlos]

Laws of logs apply here don't they?

log (x^y) = y.log x

C=(1-D)^T

ln (C) = T ln (1-D)

T = ln(C)/ln(1-D)

I would think

What things?

Who are you and what have you done to my cuppa?

but since it's obviously the flavour of the month here in Amiga.org, my answer is: socks.

Ick. I hadn't realised people had stooped so low as to be chewing on the things now...

Still, can only be as bad as aloe vera ;-)

-edit-

Which reminds me, I was supposed to be making some tea :lol:

[Karlos]

So what are you graphing/solving anyway? Whenever I see T I instinctively think of absolute temperature...

-edit-

But I'm damned if I can think of anything that has a direct power dependency on temperature ;-)

Oh, something incredibly trivial. I was trying to work what battery manufacturers call "shelf life". They say that the shelf life of batteries is how long they take to get to 85% of original charge, just sitting there and not being used.

Ah, I see.

I needed to get this for other kinds of battery. It may be pointless, but it beats chewing a sock, even if I do need the fibre.

Combustarse say: "man who eat vindaloo has no need of fibre"

I think you'd get more semi decomposed protein and sugar and amines than you would fibre from chewing "The Sock" ;-)

Especially bloodline's socks

That *is* "The Sock" :-)

Hmm, now you have me wondering. Are there any other serial sox offenders here that we don't know about?

Name and shame! :lol:

[Karlos]

I can just hear the enthusiastic feminine chorus of "Get your coat, you've pulled!" :-D

-edit-

Something tells me the catchy title of this thread is keeping people at bay :-D

Either that or they've actually read it :lol:

[Karlos]

It's basically an exponential decay curve, just like any other proportional (as in the current absolute rate is always dependent on the current amount) decay.

The manufacturers could have chosen the half life of the cell to make it more obvious, but I doubt that a cell at 50% charge is not much use so they picked the 85% threshold instead.

[Karlos]

You sure are into cells dude :-)

-edit-

That said, I can think of worse cells to be in of a Saturday night ;-)

[Karlos]

You'd find it easier to stick to the sock, er...

As for explosives, I do recall some very interesting reactions I had to set up when I embarked on my PhD.

I needed to prepare isopropyl 1-napthyl sulfoxide (and also the sulfone) in order to ascertain the barrier to rotation (if any).

The first stage was to prepare the thioether and then oxidise it up. I ended up having to perform a reflux of neat propene at -6 C directly on napthan-1-thiol with an acid resin catalyst.

I had a dry ice cold finger and gently passing dry propene direct from a gas bottle, diluted with nitrogen to be on the safe side.

I went away for lunch, came back and found someone had been in my fume hood to get something and had knocked the assembly, pulling out the N2 line. They'd reattached the wrong one and were now diluting the propene with compressed air.

Good job nothing sparked in there!

[Karlos]

Are they talking about multiple bond order between oxygen and platinum?

If they are talking about oxoplatinate species, my first guess would be that they are good oxidising agents ;-)

Mind you, nothing beats perxennate as a source of reactive oxygen...

/gets coat :lol:

[Karlos]

Yes, there's more to it than oxygen transport :-)

However, if someone did improve upon haemoglobin, it would effectively improve the aerobic fitness of the individual, giving them better endurance before they get lactic acid build up and so on...

Of course, platinum, like most heavy metal elements is toxic as hell - a slight oversight perhaps should any of these biomechanical corpuscles break down ;-)

Your comparing a crusty old sock to Aloe Vera??? Thats a bit of an understatment I would say, crusty old socks have far more appeal than a hearty glass of Aloe Vera juice anyday :-P

What, even with the septic cat juice chaser?

Yes, even with a septic cat juice/ear wax cocktail...hmmm, what could we call that and would you frost the glass with sugar or salt??? Thinking caps peoples :-D

Might as well float a couple of veggie-mince derived turd nuggets in there too

blurrrrrgggggh!
