Zooming in on Brownian motion
Audience:
Tags: probabilityrandomnessbrownian-motion
This is a short video introducing the diffusive scaling property of brownian motion with an animation zooming in on one point. There is a voice-over math explanation for the first two minutes, and the last 4 minutes just consist of the zoom with an original ambient piece of background music.

Nice visuals. However, I would like to see some more explanation of what we’re looking at, the last 4 minutes were really long and it was really hard to understand what is happening on the screen. The explanation could even just be written next to the graph while we’re watching it zoom. Also maybe there could or should be a scale on the x and y axis?
Hypnotising. Took me a few minutes before I noticed that the narration had finished and I’m watching a music video. Good use of sound. The graph seems to stutter in relation to the axis, though that might be something to do with the youtube compression.
Explanation is clear, but aimed at someone with a good base understanding of calculus.
Well constructed and to the point. The extra time at the end leaves me wanting more math content.
1-9 Motivation: 2 Clarity: 4 (would of liked to see a clear visual presentation on its self simularity) Novelty: 2 Memorability: 3 11/4 = 2.75
gonna give +1 for the quality of the audio recording and great voice.
Pretty cool. I never thought of wanting to take a derivative of a random function like Brownian motion. And it being related to a half derivative in some way.
But this video feels very incomplete; like it only has an intro without a body, and conclusion attached. Only a 1/3 of the video had commentary. While the rest only showed the scaling of Brownian motion with music behind it.
For that, I honestly cant rank it higher than 3 because of that (1/3 of 9 is 3). His commentary on the subject was decent, but feels like it seriously lacks depth. I feel this video only served as a trailer for the next video.
You didn’t really explain anything. You tried to explain how the axes have to be scaled at different rates, but without explaining what Brownian motion even is, this is quite useless. Especially when this is supposedly be understandable by high-school students.
It’s a bit TOO short
