None of this makes sense. The absurdities inherent in reality/cosmology and human existence are so numerous it’s sickening. It’s so absurd I don’t see the harm anymore in wondering maybe we’re overlooking something or that something has been covered up, akin to platos cave and higher forms/reality being obscured by the puppet masters. I’d rather be deemed a schizo than be a cave dwelling troglodyte mistaking shadows for reality.

Learn relevant physics (definitions of charge, current, voltage, etc)
Learn linear circuit theory (ohm's law, nodal analysis, op amps, dependent sources, capacitors, inductors, RC, RL, RLC, Laplace and Fourier transforms, transfer functions)
Learn transistor physics and circuits (FET modes and operation, ideal amplifiers, small and large signal models, current mirrors, differential amplifiers, etc)
Learn power electronics (linear regulators, switching regulators, etc)
Learn to use microcontrollers and peripherals (C programming mostly once you know all the relevant circuit shit)

How did we determin that the space we occupy is actually 3d and not just 2d disguising itself as 3d?

I’m imagining a videogame or a painting (possibly a simulation) with good enough graphics/detail/input/sound design to the point where the brain only registers the sensation of space, interprets distances and makes the assumption that things have ”sides” (even though you can only ever see one side of anything) because we’re presented with a high enough amount of definition and realistic features/inputs in relation to what we expect of 3d. You think something has sides because manipulating it changes the way it looks, but what if thats only generated upon manipulation?

>You think something has sides because manipulating it changes the way it looks, but what if thats only generated upon manipulation?

The very opposite is true.

In a computer game you have a culling system to reduce computational load, so only things player sees or interacts with are computed. On the other hand, reality is quantum mechanical. To simplify it, quantum mechanics works in such as way that ALL the possibilities are computed when nobody is looking. Then they collapse into one possibility weighted by probabilities upon observation. This is like a reverse of a computer game culling system, making it MORE computationally expensive when nobody is looking. Hence why quantum mechanics is so immensely hard to simulate on a computer.

https://en.wikipedia.org/wiki/Path_integral_formulation

To sum it up, Nature seems to work in an opposite way compared to how a computer simulation would work, almost going out of it's way to "waste computational resources", implying we probably do not live in a simulation.
>>
>>12994042
What about our observation forces something to settle if untill observed remains unsettled? And what narows down possibility to probability to certainty and when is it decided that the final image is set? Wouldnt all of this mean that everything would always be different?
You’ll have to excuse me, quantum mechanics is not my fourte

what is consciousness?

>>12991489
It's a complex pattern of quarks and electrons moving at certain velocities and directions.
Just use, simple linear algebra to calculate those directions and we can simulate it, just think about it.
Or maybe we're Boltzmann-brains that get created by a universal process
>>
>>12991489
The brain is always looking for patterns and anticipating the future. At some point it gets so far that it starts predicting its own behavior, and at that stage you feel like you are conscious. It's like those déjà vu moments when you feel like you've experienced the same instance before, just because it's accidentally feeding into your long term memory. It's the same with your thought but all the time

I'm applying to universities next year. Since I'm not sure if I will be accepted to MIT can you guys recommend some colleges in US that are easier to get accepted, but have good education. Friend of our family has manufacturing business in US and he says Colorado School of Mines and Rose Hulman produce great engineers. Are those two really that good for bachelors in Engineering?

Can any one of you fantastically intelligent nerds help a post-grad chemistry student understand how the science realm is attempting to observe dark matter/energy?

I understand the mathematics behind it, but I want to know how we can observe it without the use of photons.

i think they don't really know how to yet

there are some labs where they have gigantic tanks of heavy water in hopes that they'll get lucky and some dark matter particle with a 0.000....1 chance of interacting with the water will eventually interact and they can record it, i think. don't know about the status or results of those though

Because Freud and Jung were just rambling schizos. Because as late as the 1970ies you could still get away with building your career on obvious pseudoscience. Because even the ''''empirically'''' sound psychological methods like CBT are based on ludicrous models that have no relation to reality. We only use them because all the other pseudoscience they came up with is even worse.

And most importantly, because even in current year there are STILL therapists and other quacks out there in the wild applying these mixtures of 19th century ''''''science''''' and new age esoteric babble.

>>With the replication crisis of psychology earning attention, Fiske drew controversy for calling out critics of psychology. In a letter intended for publication in APS Observer, she called these unnamed "adversaries" names such as "methodological terrorist" and "self-appointed data police", and said that criticism of psychology should only be expressed in private or through contacting the journals.
I'd also say way better to have independent, self-appointed data police than official, governmental data police

We use them because they work. Not for everyone, sure. But to deny that methods like CBT have some positive effects on certain people is ludicrous.

>>
>>12979946

As hominids began eating softer and softer foods (grains) the need for large and powerful jaws decreased.
Smaller jaws, means overcrowded teeth, pushed together, this the need for floss.
Teeth used to have spaces between them, not anymore.
So the English and the Chinese have an evolutionary advantage, crooked, misaligned teeth allow for space between teeth, less tight spaces for debris to collect causing pain and toothed decay.
Be shure to use your white strips and pull your teeth closer together with braces.
