How can the net amount of entropy of the universe be massively decreased?
>>8449011
I have an idea.
>>8449011
Have an intervention with the universe and inform it that it needs to clean up its mess.
-go to a new universe
-take gibbs free energy from another universe (e.g. take stars from another universe)
-find God and ask for his help
-discover that the laws of thermodynamics are approximations that do not hold accurately under some circumstances
i think those are our options
So anyway, I understand and can visualize how composition of shift and rotation would always have a fixed point, but how can it remain fixed, when you take a homothety of < 1 after that, unless of course you specifically choose it's center to be that fixed point?
I've seen some proof on stackexchange, but it included linear algebra which is obviously unacceptable, since it's a FUCKING ANALYSIS book - intro chapter of the first volume in fact - and you're clearly supposed to be able to solve it without linear algebra.

It's a linear algebra question...shift and rotation are linear operators.
What's the book name? chapter? question?
Is this good or nah
It's basically a Big Book of Trivia Facts (tm).
Interesting but not substantial. If you want to read it for fun go ahead, but don't expect to get much out of it.
>>8448914
I completely disagree with this poster, if you are a high schooler or freshmen undergraduate in science it will probably be new to you. If you are already well versed in math/cs/physics then it probably won't impact you the same way. It's one of those books that is mindblowing in your teens, but it is very time dependent on reading before you already know the topics it discusses.
it blew my mind at least when I first read it, got me interested in cognitive science.

agreed
touches some big ideas of the mysteries which are logic and our mind
So do humans just read and then die?
>>8448874
they also invent, teach other humans how to live and survive, travel, study and discover thing, try stuff like flying, and falling, and digging holes..... idk, i think there is a lot of stuff to do both to help us survive and to simply enjoy... I don't share you nihilistic view on things...
Some die without ever really reading.
>>8448874
If they're literate.
IS there any reason to believe gravity is a fundamental force and not just the result of the curvature of space-time as Einstein said?
Or has a good portion of modern physics been wasted on this bullshit?
>>8448870
Gravity appears to be a force with aspects of time and space so possibly. Einstein was a manufactured fraud though, his gf had all the brains and I ain't even making that up. There were shadowy men behind the curtains, his handlers, feeding him these sorts of things so he could regurgitate them with the masses accepting him as a benign philanthropic "scientist". An actor really.

Top kek. Average medical paper right there.
Children who are more intelligent tend to have myopia because they read more books, not the other way around.
>CONCLUSIONS: The conducted clinical observations suggest that children with myopia may have a higher IQ. This relationship is most probably determined by genetic and environmental factors.
really fucking deep, thanks for this valuable insight medfags.

>he thinks that "book smartness" and intelligence are same thing
I'm sorry to break this to you, but IQ is highly hereditary. You can try memorizing all the Aristoteles' works, but you won't get better score in Mensa's test as a result.
Whether for school or personal enlightenment, share your study regimens with me.
For example, I procrastinate to a degree where I've had to do another year at university after dropping out of my classes because I was afraid to sit down and focus on the subjects until it was too late.
t. idiot
read some study books like "study smarter, not harder". It is an easy book and has a lot of really good stuff.
Scheduling and stuff is good, also sometimes you just have to use willpower. I know it sometimes feels like magic when you suddenly out of nowhere decide to work on something, but you can force it sometimes too.
I have done a good job at keeping my shit together so far. On year three of an earth science and math program with a 3.7 GPA.
Study regimen includes long, disproportionate amounts of time dedicated to one subject or course. Usually, I'll dedicate around three continuous hours to as many subjects as I can per day. Example: math exercises for three hours, paleontology reading and essays for three hours. General education courses usually get one hour per week.
It gets ridiculous on weekends, though. Usually same regimen but in 5+ hour stretches. In some cases, 12 hour stretches if I have a large paper due on Monday. I work slowly and procrastinate often. And those stretches are usually littered with distractions.
'Do not strike when the iron is hot, make it hot by striking'
I've obsessed over study optimization. Read all the Tim Ferriss bullshit. Tried nearly every nootropic.
The only thing that works is good habits. And the only way to create good habits is will power.
You just have to power through that initial 2 weeks or so of habit setting. Once it gets burned in its actually quite easy.
Is there any point in attempting to go into STEM if you're 25+?
Do we really have a harder time learning new things and understanding new concepts as we get older?
>>8448756
It's never too late to learn unless you are about to die, anon-san
Yes we do but if you have a healthy brain aka don't eat shit on a bag or can and do some excercise, you won't lose your brain's capacity of memory
I don't know. There are theories about it but I don't think anyone actually knows. It is hard no matter what. You can also read books on learning and that should make it easier. I think that it is possible to learn faster and become smarter by studying how to study, perhaps even more than when you were at your peak.

How do we stop the end of the universe, or escape it if nothing can be done to save it?
I am terrified at the thought of a conscious being experiencing the slow decay at end of all things, and I would do anything to keep that from happening.
It's time to begin the think tank, /sci/, to lay the foundation for our salvation.
>>8448690
We could start a new universe. Some believe that has already happened.
Turtles all the way down anon
>>8448690
The salvation is the heat death of the universe.
>>8448690
>I am terrified at the thought of a conscious being experiencing the slow decay at end of all things, and I would do anything to keep that from happening.
Then it sounds like it's on future generations to stop having kids when it gets close to the end of the universe.

Is there a scientific reason why these skeletons are so spooky?
>>8448629
Because everyone is a spooky skelly inside us
But hey, you can also be a spooky skinless man as well, in fact everyone is spooky inside anyway

it's unhealthy to fuck skeletons

Hey /sci/ My friend and I have been working out this problem on a practice exam and we cannot for the life of us figure out the correct answer for the Cy and Ey reaction forces. We were able to find Ex, Cx, F(DF), and F(HG). We've been trying different methods but can't come to a consensus on what the right answer is.
Would anyone be willing to take a shot at it?
Update: we got Cy but still are struggling to find Ey

if you push 6.6lbs of force on either size, the total is still 6.6lbs
>tfw have to have wisdom teeth out tomorrow
>tfw almost certain my jaw is too small for its teeth due to malnutrition
>tfw can't do anything about it now, it's too late
hold me science people and discuss malnutrition if you want
getting my wisdom teeth out, i didn't care. I barely even knew what I was going to the dentist for, thought it was just something everyone did in their late teens.
ended up being one of the worst experiences of my life. I lost like 10lbs in two weeks and had daily anxiety attacks and depressive episodes for those two weeks afterwards, and the anesthesia gave me brain fog for at least a few days afterwards, and I'm pretty sure I tried to throw up right when I got home from the procedure.
Have fun. :)
>>8448410
If that is true at any level, I'm really happy I have teeth small enough for the wisdom teeth to fit in nicely with their friends.
