This is nuts

well?

Is dysgenics a major problem in modern society? How long until society collapses because nobody's intelligent enough to maintain it?

could this dea of intermolecular tension prompt other research, or is it not in line with prevailing theory, or conversely already a subject of research?

I still haven't found a satisfactory explanation of this phenomenon.

i dunno, I just went through the biology regents test and i remember most of it
really reminded me that up to early highschool is pretty basic stuff that everyone should know
covid was good proof that you need a population that is versed in basic biology and able to comprehend charts and scientific charts and graphs

looking at physics and yeah I don't remember most of it off the top of my head. It's mostly useless computing. On the other hand I'm looking at a question about how light is reflected off a surface and plenty of people really do need that

yeah math is worthless though beyond algebra
geometry and trig is a waste of time. Chances are they will have to relearn it when actually applying it anyway cause it usually doesn't equate.

history is important cause we live in a society
literature is kinda useless, but this depends heavily on what is actually read in school, which differs a lot. The technical aspects of literature, you can get rid of.

chemistry... yeah also probably useless overall

Well, go ahead, explain this if you’re so smart.

EXPLAIN THIS TO THE MILLIONS OF AMERICAN ZOOMERS, /SCI/
Yes it's genuine, they are not faking it.

Here.

I remember my dad showing me this trick when I was little and I was so mesmerized I showed it to all of my classmates.

It is a troll question that assumes the plane's engine connects to its wheels.
The jet engines push air back and both the plane and its wheels gain speed. If the belt then accelerates against the plane's motion only by kinetic friction can the belt speed more than its opposite effect on the wheels:
Ff = u Fn
Kinetic friction is a constant until the plane starts to generate lift, then the friction only decreases as Fn decreases. Kinetic friction between wheels and belt stops when they match speed after the belt's reactive overacceleration. However kinetic friction as a force between wheels and plane, being the only force against its movement, remains the same or less no matter how fast the belt or wheels run.

can sci explain this?

How?

/sci/ bros we got too cocky

Fuckin' mirrors, how do they work?
