April 9th, 2019. It has been 8 years and 20 days since Brownian motion #1 (basic properties) was uploaded to KZfaq. Supplies are running low, but we continue to wait patiently for Brownian motion #2.

It's 2021 now. The vaccine is out and things are looking up. But it's still not as good as life would be with brownian motion #2. We are patiently waiting.....

It’s 2021, we’re on the 3rd wave in my area, numbers are going down, vaccine roll out is quite smooth but still no Brownian motion #2

@lucapontiggia31239 жыл бұрын
What a gem of a video. In the future, don't hesitate on describing even the most "obvious" concept - for example, it would have been nice, if you had spend an extra 2 min on describing what the covariance is - just as you did with explaining to us what it means to be normally distributed in this specific context. This is easier said than done, as one has to assume some level basic knowledge. You have a clear, illustrative and simplistic style of explanation, a rare find. I can imagine such videos are hard to make, but I hope to see more of the kind. Well done.

thank you so much stepbil! I did not get this topic because no one had ever explained it as clear as you did. In particular, I did not link the variance value, t, to the x-axis. I thought the variance value of t just happens to have the same letter as the name of the x-axis!!! that the value of variance increases linearly with time is just such a revelation to me.

Man, the fact that you drew the normal distributions sideways was key to understand the topic. Literature often overcomplicates things (sure: keep things formal, but would it hurt if they include simple explanations/examples?).

Hi, I have question. Q) Suppose that a stock price, Skype'ta, follows geometric brownian motion with expected return u, and volatility v: dS(t) =uS(t) dt + vS(t) dW(t) What is the process S^n (t)? Show that S^n(t) also follows geometric brownian motion. What are the drift and volatility functions of this process? Anyone can help on this? I would really apreciate any help. Thanks

QUESTION: The martingale property basically says we expect to be in the future where we currently are... but the 1) and 2) property of a BM was N(0,t) so shouldn't our best guess be that "in the future, we are at the mean 0". ? Help me see why this is not contradicting. I feel like we both expect to be at 0 AND at where we currently are (martingale property) Thank you
