Why world looks chaos on atomic scale but it is uniform on higher scale?

Hey guys, I am thinking about world at small scale and world at larger scale. Why world is more chaos at smaller scale and why it is more smooth and uniform in larger scale?

What examples are you thinking of re: chaos at the atomic scale and uniformity at the macroscale?
 
Thinking about what we would see if we go on atomic scale. It's like particles popping into existence, electrons coming and going but on larger scale we see nothing going heavily like that.
 
Doesn't atomic scale looks chaos?

OK. Virtual particles are certainly not something we see in the macro world.

Don't know what this means. Cars come and go on the highway.
I think what you might want to consider is that, from the time we are sapient, we get used to the way the world works at the macro level. The atomic scale only looks weird because we're not familiar with it.

If we were atomic-scale creatures, then radio-decay and Cherenkov radiation and virtual particles would be perfectly normal and we would be agape at what a single mass of 10^26 atoms could do with a canvas and a paintbrush. From that point of view, it's the macro world where all the really crazy things happen. Like life. And da Vinci.
 
I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...
I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...
