This is just like the classic physics observation by Robert Brown of the random walk traveled by pollen particles floating on water, demonstrating random thermal or "brownian" motion.
For example, although the brownian motion of a particle appears random, it can still be causally described if we know enough about the motions of the particles surrounding it.
To elaborate on DeWitt, an l(0) process is white noise and an l(1) process, a classical random walk ("brownian motion"). l(2) is a bit harder to describe: perhaps the location of a vehicle tracked by an inertial device, where the acceleration is "noisy".
Taleb doesn't argue that outliers are impossible to quantify, he just thinks that the present ordinary brownian motion model underlying mathematical finance should be replaced with fractional brownian motion.
Một cách để vượt qua những chuyển động brownian là mát cơ chế để trỏ, nơi các nguyên tử không còn như rung mạnh.
Bởi vì ratchet đủ nhỏ để có thể chuyển động brownian chính nó.
Actually, without the work itself there would be no walking, even under the brownian rachet model.
Uhh, how am I "dead wrong" because of the proposed brownian ratchet model?
If you want to say that the function that the G proteins do lead up to the myosin walking mechanism then please as a consequence of brownian motion itself, fully spell it out.
The mechanical work exploits and overcomes brownian motion resulting in a walking motion, thats usually what machines do, exploit their natural surroundings.
