>even physicists can't handle elementary mathematical ideas
and this is why science is dying, how do you even get this far without realizing the importance of math?

Group theory is a rather useful tool if you are going to do any sort of theory work. If you are an experimentalist, you can probably get away with only a glancing knowledge so that you can pretend to understand the theorists.

I don't imply it is difficult. The thing is, this is abstract, and physics is practical. My question is very humble, could any physicist tell me when does algebra become relevant? I mean abstract algebra, not stuff like matrices stuff. Is it usefull to know the properties of an abelian group for a physicist? I know that it could become relevant when talking about vector space, which leads to matrices, which is usefull for physicists. But all the abstract stuff is useless right?

Anyway, you can always place a breakpoint at that line and get into the function to see if they actually do what they do.

Java has nothing to do with science/mathematics. It's not even used in scientific computation since it's so slow compared to C/C++. GTFO and never come back.

Place a what where to get into which function to see if who does what?

Please explain. I'm a beginner to Java.

He was important, but not in a good way. Many biologists still believe in his theory of evolution even though there is ever-growing amount of evidence that debunks it. I'm not saying that everyone should believe in creation like I do but science can't progress if scientists keep clinging onto old failed theories instead of being critical.

Ok, thank you.

With sociology and gender studies of course.

What a pity. Up to the 1950s there was some good research in psychology, for example on propaganda, brainwashing and psychological torture. Today psychology students are only taught "gender" bullshit.

bad luck? in terms of morbid obesity there are some people with legit metabolic disorders, but the vast majority of fat people who are unhealthy are just disgusting slobs who have no self control.

An interesting watch. To sum it up, everybody has a 'natural weight' that they will gravitate to if left to their own devices. For some its higher than others, hence why some people struggle with weight more than others. These people will require higher levels of self control to maintain a healthy weight.

Calories in calories out

People are fat because they eat more
People are skinny because they eat less

People are often fat because their parents didn't raise them to eat properly. The amount of times I see some dumb ass mother feeding her infant child a pack of crisps, it's disgusting.

If you eat properly you will be healthy
If you eat poorly you will be fat

The tiny exceptions to the rule do not make up the ridiculous number of people that are fat in the world today.

It is harder to eat healthy nowadays than it was in the past, absolutely everything you see in supermarkets are pumped full of unhealthy shit. If you want to be healthy you've got to pay attention to your diet.

Well there's the argument that the brain lacks other senses not known to us yet. If someone is born blind then they live their life not knowing what sight is.
There's the possibility that humans are living this life not knowing how to perceive certain senses but it's possible that through extensive evolutionary processes the human brain may acquire these sense.
However we have been evolved to conform to the senses needed to live on Earth and until we explore other areas of the universe, we may just be limited to these given senses.

>>8427306
Human brain is done, we have reached the peak o our intellectual potential its all downhill from here faggot.

>>8427306
There are lots of senses and therefor ways to process certain information, that we lack.

The human brain is also not the best at every feature we do share with other animals.

Some animals have been proven to have faster processing of visual information and a better short time memory.

Natural numbers represent discrete countable tangibles.

Integers extend that representation to nothing and debts of tangibles.

Rationals allow for fractions of tangibles.

Real numbers represent continuous tangibles like time and temperature.

Complex numbers represent tangible state variables in a linear AC circuit environment.

Okay looks like we've got everything.

>>8427279
>Only numbers representing tangible, finite objects exist
No they don't. Your image was right, numbers don't exist.

Math certainly was inspired by nature, and you can apply the concept of numbers to real life things.
But math is purely conceptual and build upon axioms, created by humans.

>>8427279

Numbers only exist insofar as they are ideas. Finite numbers correspond directly to objects in the real world. Infinite numbers perhaps only correspond to other ideas, such as how many finite numbers there are. They're both still ideas.

Alternatively, no numbers exist because it's all just a symbol manipulation game.

Because if you're sick and malnourished, you lose hair. It's not a good sign.

Yeah, that's why it's so common to see chimps with picrelated kind of hair.

middle ground, he's not full of shit but he's not considered likely to be successful either, academics have been unable discredit his proposals but remain skeptical

a 2005 MIT tech review said "SENS does not compel the assent of many knowledgeable scientists; but neither is it demonstrably wrong"

but biotech is advancing quickly and i'm no
expert so who knows

Simple, long wire acts as an antenna and picks up the transmissions. You have a shitty power amp, senpai as this should not normally occur.

I guess the wire acts like an antennae. It is a bit over 1m. Its long enough to pick up plenty of radio channels.

Could this be from a magnetic field interference produced by the speakers or amp?

If it really all were a simulation, those who died would come back in some form or the other

Inb4 they just get deleted and don't come back but you will

Given that condition then it's at the very least not a simulation for everyone else.

Therefore there exists an entity whereby this world is not a simulation.
