Have you ever thought about the fact that rotation just happens to be a symmetric transformation? Imagine how fucked the universe would be if it weren't. Every object would be warped and mangled topologically if you do any rotation and you would never be able to undo it to get back its original form, but now apply that to your entire frame of reference. it would be like warping the entire universe irreversibly. Isn't that horrifying? Nothing could build up any complexity without being destroyed due to rotation.
It just baffles me. We are in this system that happens to have so many symmetrical properties where things can stay the same, like the metric of space, the density of objects, the energy the have, and how that energy is transferred. all it would take is the loss of one symmetry and all of that would be gone forever, impossible to be formed.
why do symmetries exist? this seems like such an amazing ass thing.

Noether's Theorem states that symmetries and conservation laws are the same things.
On the topic of rotations, check out Wigner rotation.

How would you as sociopathic scientists describe the nature of human social interaction?
Take into consideration:
• Permanent coercion (war)
• Power abuse (police brutality)
• Deception for cash (child indoctrination)

actor network theory and the socio-ecological systems model that apply networks and dynamic systems to the study social interaction offer insight.
any ecological interaction can be described more or less the same.

Is there anybody able to give me a formula for two odd questions? The first being a formula to determine how many pennies could fit into a 5 gallon bucket and the second being the force a bullwhip applies at the apex of its swing moving at 1200fps? Thank you in advance

Establish a bijection between the Long Line and R.
You should be able to solve this.

You said a bijection between the long line and the reals and not a homeomorphism. So it is actually possible and you are not trolling.
>>
>>9155538
Yeah, you read it right. But can you do it?
>>
>>9155504
So, you're basically asking for a bijection between R and R×[0,1)? (Assuming CH, which is obviously the best axiom.)

How do we create an economic and political incentive structure which promotes:
>A focus on the longterm wellbeing of all life in the universe, with a hierarchy of priorities involving:
>>The individual's right to prioritize their own wellbeing
>>The family unit's right to prioritize its own wellbeing
>>The town's right ... (etc.)
>...to the extent which a group's prioritization of its own wellbeing does not harm others in an unjustifiable or unethical way
I feel like this basically solves all of our problems. Some desirable incentives and ethical ideas include:
>Prioritization of ethical virtue
>Prioritization of not harming any living beings in a way where the avoidance of harm is proportional to their population and their ability to reproduce
>Prioritization of intellectual abilities
>Deprioritization of inconsequential vain aspirations and consumerism
>Deprioritization of hedonism in circumstances where it significantly negates the ability to focus on the longterm wellbeing of life in the universe
Is it just impossible? Can any species achieve this? Are we trapped in a local maxima of evolution which has caused us to all be selfish and this is impossible to discover? Maybe species which evolve optimally did not develop intelligence quickly, but rather develop it slowly through long years of negative emotional turmoil to develop a strong ethical system despite not quite being highly intelligent with regards to their knowledge of the universe, before intelligence and therefore self-destructive technologies like nuclear energy are discovered. This seems a great risk

We started off as finite state automatons fighting each other for resources to secure our ability to reproduce, and the ones most successful at this reproduced
Since the advent of:
>Language
>Mutable knowledge passed down through generations via stories
>Culture
>Written language
>Immutable knowledge passed down through generations via books
And most importantly...
>Science
We have discovered the ability to some day, through sufficient scientific advancement, ascend this primitive way of living.
It has not come yet but we will eventually live in a post-scarcity society where all of our worldly needs are taken care of, or hypothetically could be if we redesigned the economic incentive structure of our society.
We will be able to grow meat in petri dishes in large manufacturing plants. We will be able to grow plants and fruit in multilevel greenhouses. This sort of stuff is inevitable, it's just one of those things we will have the capability of doing at scale some day even though we aren't quite there yet. We will have the technology to protect ourselves and protect the other life native to Earth from harm
This is the issue. I think we are going down a path which won't lead us here, but there's no doubt we could go there if we wanted to, and there's no doubt this is where we could be trying to go. But it doesn't seem like we are
How do we rectify this?

Ok. say you have a toy helicopter. you are in a car/bus/truck. (whatever) you fly the helicopter so its touching no surfaces. if you drive forward will the back window come forward and hit it as it stays in place or will it move with the vehicle because of indoor circulation or whatever

If the car is stationary and then you fire up the helicopter it and then start moving the car the helicopter will hit the back window. If the car is always moving and you start flying the helicopter the helicopter will match speed until you slow down the car then it will hit the front window

Has anyone ever performed Schroedinger's cat experiment in real life? That is, using a quantum measurement as the basis for an outcome in a life or death scenario.
It need not even be life or death, something like an electric shock might suffice. There just has to be a guarantee of a negative effect on the emotional state on the subject.
The global consciousness project provides evidence that it could in actuality affect the outcome of the experiment, proving QM to be not so random after all. Perhaps one could even make a sort of quantum lie detector out of this.

As an airplane is taking off at an airport its position is closely monitored by radar. The following three positions are measured with their corresponding times:
x1 = 320.86 m at t1 = 4.40 s,
x2 = 382.01 m at t2 = 4.90 s,
x3 = 448.66 m at t3 = 5.40 s.
What is the acceleration of the airplane at t2 = 4.90 s? (Assume that the acceleration of the airplane is constant.)

I'm just posting this in case some medical student is lurking.
Is Gray's Anatomy a meme? I need a nice atlas, but GA seems to be like 1,5k pages now and I have no idea how the new ones look, the classic drawings are amazing but apparently it's been 'revisited'. I went through Netter but it seems really text-heavy and the drawings are a bit cartoonish. I had also downloaded the Regional atlas of Human anatomy but it was just bad.

I don't know much about medicine but my impression from actually paging through my copy and its occasional discussion on /sci/ is: it's MOSTLY a meme, but not completely.
What I mean, exactly, is this: GA is obviously a dated text and if you're going to actually learn and/or practice nowadays, the obvious preference among actual med people is a contemporary text with better pictures and recent context.
ON THE OTHER HAND. I doubt that human anatomy and that human anatomical nomenclature have changed significantly over the past hundred years, unless one refers to things like increased height, weight (obesity) and longevity in first-worlders. The point being that if my above thing is correct with those caveats, that GA is still presumably a somewhat relevant compendium, if not a first choice for today's professional. I have heard med people on /sci/ claim that they actually used GA in the course of their education. For further expansion please refer to an actual student/professional who will obviously know more than me on this.
I also differentiate anatomy from other areas of medicine that have obviously changed plenty (now we can cure/vaccinate XYZ diseases that we couldn't a year ago, other areas of inquiry apart from anatomy, etc).
It's a nice book to have a cheap copy of on the shelf, the pictures do have a certain cultural relevance. I'd like to read the skeletal system at some point.

Good post, yeah, that's pretty much what I read after some googling. Turns out my scripts have been using the Netter illustrations, which aren't half bad but don't really give a 'full' picture, such as my OP pic does.
I don't really understand how much things could have changed regarding anatomy, considering any bum with a scalpel can see how stuff is arranged. Also no idea why Americans have accepted anglicized notations, it makes it much more uncomfortable to learn compared to Latin.
