If convex lenses reduce or remove the need for the eye to accommodate for near work, why don't we make everyone use reading glasses, when studying or reading, as a preventive measure against myopia?

just add a layer of convex plastic to the lenses that add +0.5 every couple years or so. does it exist? i think it would be a great idea

You literally just put it on your face, and forget about it. Besides, if you periodically need to upgrade your glasses, something else is wrong with you.

What are you even arguing for? That spending money is ok even if there was an alternative that prevented you from spending said money? Also all of your analogies so far are completely unrelated to the point, I'm starting to think you sell glasses for a living

Anyone who is not a retard can be a successful college graduate and go on to do a Ph.D and do research, especially in STEM fields. Besides that, there are also supposed "greats of all time" --- this is a complete lie, and just means that they've taken their interests seriously for a long time at a high degree of concentration. Discuss.

Graduating and doing research are different activities. To some extent getting good grades is in opposition to developing proper scienctist skills. I would say that in every average high school class (30 people) there would be ~1 person suited for scientific work. By that I mean, such person has necessary personality traits and some level of intelligence.

Greates of all time get really lucky most of the time.

Disagree. Genius-tier intelligence (140+ IQ) is something you're either born with or you're not. It cannot be acquired through hard work. Sure, midwits can make some scientific contributions through rigorous studying and working, but it will always be dwarfed by the work of geniuses. Talk to someone who is ~110 IQ, then to someone who is ~135 IQ or higher and tell me you don't honestly notice a significant difference.

It is said (often by the greats themselves) that most of the greats would not pass college these days.

Colleges are now a waste of time. You end up being taught by people who have never done anything in practice, who were taught by those who had never done anything in practice, teaching you courses made by people who had never done anything in practice. It's like learning biochemistry, the biology of sensory perception, physics of cutting, the principles of electric heater, and then after years of this cutting up an onion once, when you want to become a cook.

This desu - maybe it is in retrospect and I knew algebra well enough to start, but all my “flair” for algebra tricks came from noting I need to do intermediate steps in calculus like partial fractions etc

Otherwise they just feel like meaningless expressions you’ll never use so you’ll forget about it

Not him but I get filtered hard by continuity. I have read through some of The Elements but it is no wonder they spent so much time on it. Geometry requires intuition and not hard knowledge, just see how difficult it is to formally and completely define a triangle.

It's just a tradeoff. Do you want it dark when you go to work or dark when you come home from work?
Dark in the morning is better in my opinion, because people are indoors at that hour much more than they are in the evening. Driving to work/school in the dark sucks, but it's better than driving home in the dark when you're tired at the end of the day.

Water seems to have certain propperties which allow the polar watermoleculy to arrange and emiting certain electromagnetic waves which resemble the molecule that was in the water before.

Wasn't the originator of homeopathy Samuel Hahnemann, who formulated his 'law of similars' from the observation that bark of cinchona (the plant quinine is extracted from) produced physiological effects similar to malaria symptoms? It seems like it was a reasonable hypothesis at the time, which somehow survived newer research disproving its underlying misconceptions (similar to chiropractic).

Homeopathy only works for idiots that don’t know what it is, it’s just the placebo effect in action.
As long as the substance in it isn’t bad for you it’s honestly ok for minor problems, that is if it works, and if it did work it just confirms that your problem was actually psychological.
I wish that I didn’t know what homeopathy and placebos were, maybe taking some of this shit can help certain people without resorting to drugs, there’s a lot of hypochondriacs out there.
