ITT: fields or subjects that interest you, but every time you attempt to study it you remember how boring it is, or are reminded why you didn't go into that field.
For me it's physics.
I Used to be a Physics major. I'm a math major now, but I still have interest in GR. I got through Differential Geometry, but every time I try to study even the most basic GR, I get so bored and I am reminded how uninteresting Physics is to me. Same with QT/QM.

Is some adaptive form of autism going to be the next phase of human evolution?
Artists don't reproduce. Only Chad and Tyrone do. Welcome to dysgenics. If von Neumann was born in China today he would have been cloned many times over. But the west believes in cucked equality so our civilization will basically become Brazil.
I've wondered about if you took people with Down Syndrome and kept having them reproduce with one another, if it would eventually come to a stable and relatively healthy population. What sort of time scale and probabilities would be involved for a reasonable outcome, or do the means exist at all.
>>8101399
That's also my assessment, right down to the Brazil comparison.
But do autists really believe in anything outside their personal space? Communal living is complete hell for them. They tend to agree with leftism because they know it hurts Chad, but in practice they are aloof. Aloofness plus money equals Brazilian style elitism, even if the autists aren''t snotty about it.

Why the hell is chemistry so fucking inexact, /sci/? I'm studying salt solutions and every two seconds the book makes a new approximation because fuck you that's why. It's fucking rage inducing.
that's how all fields work, deal with it.

I'm not having the same issues with maths or physics though. Everything there is explained, every formula. Instead chemistry just tells you to do this then do that then do that without really explaining what the hell is going on

ever noticed how you only study ideal situations?
Obviously I don't have any mathematical or scientific training or whatever so this could very well belong to a sqt, but isn't basic algebra (probably not a proper math object) supposed to be transitive? Like if a=b and a=c then b=c? Then why is (-b+(b^2-4ac)^(1/2))/2a) ≠ (-b-(b^2-4ac)^(1/2))/2a) even though they both are equal to ax^2+bx+c=0)? Also there's the if a=b then a+-*/c=b+-*/c property. It doesn't hold for "x=7 then x/(x-7)=7(x-7)" Does this mean math is broken? Do we just patch it up because it's useful irl? Doesn't the fact that there are undefined operations in basic maths prove that it is broken? Wasn't something like this, an undefined result, what killed, for instance, type theory?
>>8101179
You can't equate an expression with an equation.
>>8101179
If we take b=0, a = -1, and c = some positive number, then your question translates to
"if (-1)*x^2 + (0)*x + c = 0, and if x = ((-(0)+((0)^2-4(-1)c)^(1/2))/2(-1)) or ((-(0) - ((0)^2-4(-1)c)^(1/2))/2(-1)) , then shouldn't ((-(0)+((0)^2-4(-1)c)^(1/2))/2(-1)) = ((-(0) - ((0)^2-4(-1)c)^(1/2))/2(-1)) be true? No, if x is this number, OR that number, it does not mean it is this number AND that number.
What exactly happens in your body when you reach your breaking point?
How does mental and physical exhaustion differ?
And how can you know what your true and imagined breaking point is?
Examples: when I am running and feel the urge to stop but keep going on until I feel like I just have to stop. Was this my phyiscal or psychological breaking point or was it neither? Could I still have went on for longer? What prevented me from it?
Similarly when studying and I just feel too tired to focus. What exactly is it that prevents me to study for another hour or two?
And: how can you push your limits? Practice?
>>8101085
pratice helps build endurance in almost all things. To answer your question it's a bit of both it's a safety guard/device in your mind and body to not over exhaust anything. Just listen to it and don't push yourself to hard you will probably won't amount to anything anyway.

I'm not at all sure if this question is too asinine or not, but I wanted to ask /sci/ about the relative pro's or cons of transport by pipeline as opposed to transport by rail or road or other vehicle.
Whenever a resource is available as a fluid, it's generally transported through pipes. We rarely see companies extract oil from the ground and then truck it from place to place. Similarly with water, it's delivered via pipe, as it's cheaper.
So I'm wondering, say we fluidised the worlds largest traded solid resources, i.e., convert iron, aluminium, copper into a sulfate or nitrate salt, and then dissolved it in water to be piped from place to place, how much on transport costs alone could be saved? Similarly with polymers, let's say we converted plastics into simple hydrophobic monomers that could be dissolved in crude oil and transported along with existing oil pipelines, to be reconstituted at local refineries into plastics, how much, if any, could be saved? This taking into account predominately local manufacture; instead of shipping a car from Japan, the component parts of said car are fluidised wherever possible, piped to a local factory, where a the vehicle is manufactured and then sold.
If 3D printing technology takes off (an admittedly doubtful state of affairs) and every village has the equivalent of a large multipurpose factory in its backyard, wouldn't economics eventually require an end to the transport of large capital goods like cars in favour of basic resources, with capital goods being produced locally? (Note that this point is an aside, this thread is not meant to be about 3D printing, it's about roads and rail vs pipeline).
I've tried googling and came up with nothing, not even information about the most transported goods, but came up with zip. Hoping /sci/ could help.
>>8101083
The biggest (of many) problems with this approach is that melting say, iron takes a fuckton of energy. And you have to heat the entire length of the pipe enough to _keep_ the iron liquid, or else it's just going to solidify a mile down the pipeline.
>>8101087
The post mentioned that resources like iron would be fluidised by conversion to an aqueous salt like a sulfate or nitrate, and then transported by being dissolved in water. No molten metal needed; I'm thinking more of an add on to existing water distribution networks with a system of refining out the bulk goods before the waters use for drinking or agricultural purposes. Perhaps I should have been clearer on this point.
>>8101083
>how would a theoretical, untested and unproven method of transportation for goods, which doesn't even yield results in google, fare against the established methods of transportation of goods, for which actual data exists

how the hell are we supposed to know

This video doesn't say why we'd be limited to the local group.
According to google, space is expanding at 74.3 km/s/megaparsec. Things just over 13 billion light years away are moving away at faster than the speed of light.
Also, since at all distances closer than that the expansion of space would be less than the speed of light, the fact that space would be expanding while the light was traveling should not matter.
Sure light that we see may be from things that are no longer reachable, but wouldn't 13 billion light years be the real limit of possibility?
>astrophysics
This whole video is kind of pointless because it only accounts for our current understanding of physics which will undoubtedly change drastically by the far future relevant to this video. It's entirely possible that we will be able to bypass the speed of light or even leave this universe if there is such a thing as multiverses.

Evolution is often spoken of factually, but in fact only changing the properties (as opposed to the nature) of descendants is directly observed; this is nothing new, breeding has been done for thousands of years. Evolution is the theory that this can eventually lead to new species. Yet speciation has never been directly observed, only inferred. All the examples of it being observed, are based on mating preference, not innate incompatibility; by this standard, Ethiopians and Greeks of ancient times were different species, since they did not mate with each other.
Also, abiogenesis has never been replicated, which is strange. If RNA can happen by accident why can't that process be replicated in experiment?
>>8100563
>Yet speciation has never been directly observed,
Yes it has. It's actually fairly common in insects.
>>8100599
Nope.
>This is a simplified model of speciation by geographic isolation, but it gives an idea of some of the processes that might be at work in speciation. In most real-life cases, we can only put together part of the story from the available evidence.

Do you enjoy shooting yourself in the foot?
Post a subject or skill that everyone should be a master of in your opinion.
Mine are:
Philosophy (Ayn Rand's Objectivism)
Logic
Math
Personal Finance
Basic Economics
Nutrition/Body Health
Computer Programming
And build your specialization on top. Why computer programming? Because computers are huge value creators relative to price/energy expended.

>Philosophy (Ayn Rand's Objectivism)
so that everyone can see just how batshit and retarded it is?
>>8100353
Ayn Rand is not a significant philosopher, and Objectivism is wildly anti intellectual lighthearted nonsense.
