Okay, I'll try...I happened to be looking into Fick's Law when I read your response to G_Burnett and viewed the video on the other thread (Toronic Concepts). I had been at
Brownian Motion.... I'd been surfing white noise all day.
The Narrow escape problem is an ubiquitous problem in biology, biophysics and cellular biology which has the following formulation: a Brownian particle (ion, molecule, or protein) is confined to a bounded domain (a compartment or a cell) by a reflecting boundary, except for a small window through which it can escape. The narrow escape problem is that of calculating the mean escape time. This time diverges as the window shrinks, thus rendering the calculation a singular perturbation problem.
This struck me funny....yeah, and
beam divergence. I was going to say Time is of the essence....but I wasn't sure, so I didn't.
"Avicenna adds that the ‘Necessary-Existent-due-to-Itself’ has no genus (jins), nor a definition (hadd), nor a counterpart (nadd), nor an opposite (did), and is detached (bari’) from matter (madda), quality (kayf), quantity (kam), place (ayn), situation (wad’), and time (waqt)."[
Is time of the essence? (self-imposed time out)
I don't think you want to know where I've been concerning cells.....logic, ethics, metaphysics........I'm too tired now and my notes are in the car.....ugh........Now, where is that non-markov chain?.......nowhere dense set? sorry......messy, very messy.
