TIL about the arrow of time paradox. Events at the microscopic level are time-symmetric, meaning that if time were symmetrical, a video of those events would seem realistic whether played forwards or backwards. But this isn't the case at the macroscopic level. There is no good explanation for this. scholarpedia.org/article/β¦

Is macroscopic chiral inversion possible?

I've been using a chiral inverter at home (in my garage, don't want to deal with any leaks!) to make artificial sweetener from maple syrup (I know I should be using something more refined, but I like the flavor!), but the process is incredibly slow, I'm wondering if anyone else here has tried to build a macroscopic chiral inversion rig.

My take on the wave function of particles and why macroscopic world is not full of waves

The collapse theory is a very interesting and probably the most accurate explanation for the quantum observations we had in the last century but I was just pondering about this topic and i am no scientist.And tbh i dont even know calculus yet. But I would still like to share my hypothesis(more like a random thought) about why at quantum level we see probability waves but in the macroscopic world stuff looks pretty normal and only made out of particles.

It occurred to me that what if wave function never collapses but instead it exists always even when being observed but since most of the waves are centered in a particular place it appears to us as if the object is in that place.

For ex.: A tree... theres a wave function according to which its on mars but more waves are centered around the place where tree stands in others words like an electron cloud we have a tree wave function cloud which is more dense in the place where the tree is. Its not like its centered around the tree instead the tree is where the cloud is most dense.

And in the experiments when we measure the particles position we dont blink it from wave to particle instead it could be that we capture a still of the wave in a way like a wave of lets say tennis balls is going so we capture an image of one tennis ball.Not saying that waves are a bunch of particles just an analogy.

This means we are all a bunch of clouds!!!!!!!!!!!!!!!!!!. But these clouds are very small like each particle is a cloud but itβs a small cloud in itβs self so at a big level all we see is a normal thing and not a probability cloud thing

I do not claim to understand Quantum mechanics. Im just a guy with interest in it

Is it posible to predict water macroscopic properties just by knowing very well the oxygen and hydrogen atoms?

Let's say you know every single thing about the individual atoms of oxygen and hydrogen, but nothing more. You don't have previous knowledge about single water molecules. Would it be possible to accurately predict water macroscopic properties such as: viscosity, boiling point, freezing point, density at different temperatures, etc..?

Edit: I'm asking from a theoretical point of view. Hypothetically you could use as many supercomputers and spend as much time as necessary to run simulations. So that human technology is not a limitation.

If everything is made of atoms and sub-atomic particles, and they all behave weirdly, according to quantum mechanics, why doesnβt any of that weirdness spill over into the macroscopic world?

If everything thatβs tiny is governed by extremely strange laws, and everything thatβs large is just made up of billions and trillions of very tiny things, why isnβt the sum of all of those very strange tiny things, a strange large thing? Instead, the macroscopic world behaves very predictably.

For instance, if electrons are merely probability fields, and apples are made of atoms all containing electrons - why arenβt apples just βprobability cloudsβ instead of the definitive, concrete apples we experience?

AskScience AMA Series: Hunting aliens is a serious business. My name is Simon Steel, and I'm an astrophysicist and Director of Education and Outreach at the SETI Institute, where alien hunting, whether microscopic bugs or macroscopic megastructures, is our bread and butter. Hungry for answers? AMA!

As an observational astronomer, my research focused on star formation and galaxy evolution. As an educator with over 25 years' experience, I am a qualified high school teacher, have held lectureships at Harvard University, University College London and University College Dublin, and am an eight-time recipient of Harvard's Certificate of Distinction in Teaching award for undergraduate education. My experience spans formal and informal education, teacher training, exhibit design and multimedia product development. I have an interest in special needs audiences, and co-wrote, for NASA and the Chandra X-Ray Center, the first Braille book on multiwavelength astrophysics: Touch the Invisible Sky.

I'll be answering questions at 10 am PST (1 PM ET, 18 UT), AMA!

Choroid Plexus Macroscopic Structure

Hello everyone,

Is there any sources in literature that discusses the structure of choroid plexus? Most of the papers that I've read discusses it's processes, development stage or microscopic structures. I wanted to have a clear knowledge of it so I can recreate as it is seen either on a paper or on any 3D software. If any paper discusses such things for any of the ventricles, it will be helpful.

You have to make one universal, macroscopic change to the world (eg., All trees grow one cm taller overnight). If not one person notices, you get \$1B. What change do you make?

Must be macroscopic. Cannot apply solely to groups of which an extremely small amount of them exist in the world (eg a critically endangered species). Changes are universal, so you can't say "All ___ in South Carolina," for example.

Some examples might be: all dogs grow 1 extra hair (might be noticed by an owner of a dog with alopecia!), all bottles of water have 1 drop of water removed from them, etc.

If absolutely no one in the world notices the change, you get \$1B. What change do you make?

My microscopic example of Texas' macroscopic response to COVID-19

Wife (teacher) and her class are now quarantined for two weeks following a positive test by one of her students. Two other classes are also quarantined due to having the same recess time as her class.

The principal's response? "This is your fault I'm going to have to call 62 parents tonight. Your fault."

Meanwhile, she's been at home for the last two weeks because an office admin tested positive, and all office staff were wearing face shields instead of masks.

Will probably delete this post after a bit cuz, you know, Texas, and you can be sued for literally anything.
