Thanks maybe the first time I have observed Brownian motion thru a microscope

FINALLY a video that shows some experiment preparation and tips. It would be awesome if you also gave the brand of the beads / a link to buy them, and gave the result analysis in the video as well with the predicted water molecule mass (just plug displacement into formula, no formula derivation).

so imagine mr Perrin if my memory serves measuring brownian motion when he did like in 1900

Some of the motion appears to be random waves that are passing by that affect all particles the same way. Perhaps the particle is so big that when it hits a water molecule that energy is transferred all the way to another distant particle.

hi great video! thanks a lot... can you please specify what are the beeds and what is the liquid?

Hello. Do you mind if I use a segment of this video in an explainer video I am making about brownian motion? I will of course credit you

Hello. Thanks for your video. What total magnification did you use to see the Brownian motion? How can you be sure that those are microbeads? I am looking at having students take samples from a local stormwater outlet to ascertain if there are microbeads present - do you have any thoughts on that? Thanks.

I used a 40x objective. I don't recall the exact magnification.
@forrestcharnock30797 жыл бұрын
I am sure these are micro-beads because a colleague made the sample for me. This is specially made material made with rigorous tolerances (1.00 +/- 0.04 microns). Such material would not be found naturally. That said, observing Brownian motion in natural samples is certainly possible.

Since the motion is extremely fast. What is your frames per second of your camera?
@forrestcharnock30795 жыл бұрын
I cannot recall exactly, but it's pretty slow. On the order of 15 fps. When taking data for the actual measurements, we usually take pictures at one fps.

Frankly at that low a reynolds number I don't believe the beads are moving through the water pushed by ricocheting water molecules but moving with the water so that it is the water that is moving with high viscosity in bulk laminar flow. The question then is WHY the WATER is moving ? The beads carried along with it . My apologies to Doctor Einstein of course .

size of beads around 1000nm and water molecule 0.2 nm only. It is tooooo huge difference to see any movements of the beads. 5000 times linear size and 125 Billions times mass (volume) difference. I dont believe in this explanation. It like 0.000032 g piece hits elephant 4000 kg.)))
