Quoted By: >>12616989 >>12617357

In high school and during my attempt at attending a university, I barely even tried. I always thought of myself as “bad at math,” although I know realize it’s a matter of study and effort.

I dropped out after a year, and I’m now 25. I want to take a physics and astronomy pre-major program to transfer to a university and get my bachelor’s.

What’s the best way to study in preparation for math and physics? I really need to brush up on algebra and trig, my fundamentals are lacking.

There are great YouTube channels, but I also recommend getting a textbook with answers and do some practice problems. You'll also need to know calculus, which you should take during your undergrad. HOWEVER, you want to do well in those classes so I recommend studying calculus after you finish with your basic math (algebra, geometry, trigonometry). If you start studying now at least an hour or two a day I believe you can burn through most of the basic maths in 2-3 months depending on how much you remember. In terms of Physics, you'll learn everything you need in undergrad. Watch videos and do some reading on astronomy and astrophysics. It's always good to be well enough.

File: 22KiB, 632x281, LibetExperiment.png [View Same] [Google] [iqdb] [SauceNAO]
Quoted By: >>12619772

If we were to take the outcome of the Libet experiments at face value, and assume that at the smallest level our brain makes the decision before were consciously aware (if we generalize this and assume that this applies to all levels of thought/deliberation not just small random wrist movements) wouldn't this imply that our entire conscious experience is an epiphenomenon. Which is not a popular position to hold, considering the evolutionary implications that consciousness holds.

I'm confused by this assessment because in this video (I apologize for the pop-sciness of it and of my question) https://www.youtube.com/watch?v=wSYcUl2TXDc at 6:16 the neuroscientist in the panel makes claim that in the Libet experiments our brain makes the decision before our consciousness is aware, she begins to muse about why we evolved free-will. Shouldn't her question be why we evolved consciousness?

I find it kind of strange that if one were to believe the outcome of the Libet experiments, the implications would obviously point to epiphenomenalism, which seems (to me) absurd. Besides that, at the end of the talk Brian Greene begins to rapt about how determinism doesn't matter because we are the arbiter of our actions, yet 4 minutes before she contradicts him by saying that our subconscious brain is the one calling the shots. I think I'm a bit bewildered by the stranglehold that the Libet experiments hold on the talks of free will and our conscious experience. So what the fuck am I experiencing, do I have agency of my actions (I'm not implying free will BTW that's a different discussion) or is my brain calling the shots before I realize it, implying epiphenomenalism.

Why is modern science more and more censorship and faith based IE Climatechange, IQ etc etc

My geography professor for example said in one breath that the Sahara was a green savanna a few thousand years back because the higher temperatures allowed for the hydrosphere to reach more inland due to the air being able to transport more water vapor if its hotter
and in the next sentence he said that also the sahara was expanding because of climatechange and that it was never hotter before
when pointing out his obvious contradiction he just said "trust the experts"

If you see actual changes in climate it's very obvious especially when you compare tree at different latitudes, unfavorable areas where temperatures are normally far too cold for optimal growth will grow far more than normal, areas that are usually close to optimal might be too hot, and show reduced growth. >even if higher temp somehow means more ideal conditions for every plant No one is making this claim. >So temp might as well have stagnated during all the time but you cant know even if it didnt there wasnt more food for them to make use of the marginally better conditions Again this relies on the assumption that every tree everywhere has optimal growing conditions, something that is basically never the case.

All I remembered is he changed his name to N-WORD and had tons of videos of him going around town interviewing people, mostly with the purpose saying the n word as many times as possible (given it's his legal name) He also had a video of an argument between him and some female who know him well. She kept trying to get him to admit this whole shtick was a result of PTSD lol I'm now going to try to find the video in which he approaches some cholos on a stoop at night and almost gets the shit kicked out of him, thanks OP

Is polyethylene or rubber estrogenic? The molecules look pretty simple and unlike estrogen.Is rubber safer than plastic?

Happened many times now. On the first day of E&M one guy brought up gauge symmetry and would always ask questions about grad level physics. He failed the class. Happened in algebra too with someone bringing up category theory and universal constructions when we were covering the group isomorphism theorems.

Don't be that guy.

Would education be better if there were more projects instead of exams?

Rather than asking students to memorize information for the possibility of it being on a test, we instead form the education system around giving students nontrivial tasks and projects to complete.

For example, instead of giving students a bunch of formulae for geometric areas, you give them a bunch of geometric shapes with their areas and ask them to find a relationship.

Or instead of giving a bunch of surface-level historical information, students go in-depth into some historical event or person and present a project on the causes and effects, how the past shaped their actions and how those actions shaped their present and how the consequences shaped the future.

Science would be more experimental, rather than formulaic. Students would re-derive basic principles, only they would actually know personally how the formulas work, instead of "trust the science".

Literature would be more discussion based, not memorization based. More book reports instead of summary quizzes.

Schooling would be more active, interactive, effective, and would actually instill learning instead of mindless fact grinding.

Thoughts? Why is this not being done?

A top down approach treat as the most basic what was observed, found or noticed, what experiments were made, etc. and what was derived from it as a high level stuff. A top down approach, that goes the other way and treats the high levelabstractions as the most basic allows you to seem very smart very fact, but the knowledge is vacuous, as it's missing its foundations. It becomes nigh useless when you need to approach novel problems, and it has no way to notice and fix past errors, and it gives no way to approach what seems to contradict what you were taught other than to rejecf it outright.

How can people who have hard time concentrating and have racing thoughts still have very high mental skills? You would think their thought process is completely fucked up but if they can have it then it would be logical that other people can achieve it as well. It would make sense in a way that since they don't have high temper they will try to figure out the easiest way out of things which is part of intelligence but there have to be something else that makes the difference which I think an average person would be able to do as well.
