No, drill down.
get another book. Look them up. It will benefit you profoundly more than it ever would the two quoted people because you need to learn it because you are able to hold it as a system in your head, as well as others and look at and compare them.

Force of gravity: [math]F = G\dfrac{m M}{r^2}[/math]

Force due to acceleration: [math]F = ma[/math]

So: [math]ma = G\dfrac{m M}{r^2} \implies a = \dfrac{GM}{r^2}[/math]

So the acceleration any object experiences doesn't depend on its mass or how "heavy" it is, only on the mass of the planet / moon / etc. For Earth this a = g.
>>
>>16895778
Good thing the moon isn't moving, the earth doesn't exist, nor the jun and nothing is moving and the densities are the same.
Yes laymen's terms the hit the same time. The mass doesn't matter because of the inertia.
Then you get to middle school.
>>
>>16895772
The objects themselves exert different gravitational pulls due to their mass, but these are entirely insignificant because the moon is so many orders of magnitude more massive. The moon's gravity is all that matters for the drop test.

>How hard is the math GRE?
Hard is relative. The math GRE exists to sort the top performers. It’s there to help admissions departments decide who goes to MIT or Princeton, and who’s relegated to the University of Michigan. If you’re applying to schools that don’t even require it, the math GRE is impossibly hard. If you’re in the thick of elite competition, it’s just another test to prepare for.
>>
>>16895286
The math GRE is a test-taker's test, in the sense that it's just as much if not more important to be fast as it is to know the material (which for the most part is relatively basic). Admissions programs are becoming increasingly aware of this too, which is why it's becoming increasingly (but not totally) irrelevant. Doing well is a minor boost to your application and not much more, it's definitely not "the difference between MIT and the University of Michigan" lmao. Doing unusually poorly might be a red flag, though. Just make sure you're practicing under timed conditions.

>>16887338 (OP)
Professor Dave joins Bill Nye the Science Guy claiming that there is a separate distinct axis referred to as gender and that your gender can be different from your sex. Richard Dawkins rejects this and he's far more qualified than Dave or Bill. I believe Dawkins is correct and the concept of gender is unscientific. Yes, a small population (0.1%?) has gender dysphoria, it seems to be neurological in nature. That doesn't mean you create a separate axis from sex to define this phenomenon. Dave using this paper as evidence:
https://pmc.ncbi.nlm.nih.gov/articles/PMC6677266/
I don't believe this paper backs up his argument. There's no such thing as gender, only sex, but there's a small population of people that neurologically reject the sex of their body. I believe this phenomenon is similar to how people with neurological issues might reject their own limbs and believe they are foreign objects/creatures attached to their own body.

Never liked his instructional videos when I was a student because it seemed like his teaching style is oversimplified and catered more towards retard students. Now that he's doing more commentary sci-com videos, I just find him to be a cringe and morally preachy asshole. Reminds me of libtards and leftists who would scream at you for "being problematic" because you dare point out patterns and questioning mainstream thought because apparently it's a slippery slope to "right-wing rhetoric" (see his Sabine criticism video). Retards like this one always operate under their ideological worldview not so much based on objective facts.

>>16895249
I watched his full video and that's exactly what he does though. The entire premise of his video is that Sabine's criticism of academia fuels and leads to anti-science rhetoric, he doesn't even go over objective facts. You're just pulling a reverse-uno of "no u!" instead of actually pointing out the flaw in my argument, so who's the real retard here.

this shouldnt be allowed. such estrogen AIDS

I fucking hate this guy, T. reddit incarnate. I hate nuclear, too. they are such faggots and he is an industry plant
tell me /sci/, what can I do to stop this? it shouldnt be allowed
NileRed has inspired many YouTubers to do exactly this but the nuclear channel in particular is nothing but parasitic eating off of other peoples hard work and most of the time isnt even slightly related to nuclear - in other times he doesnt even have a clue about what is talked about in the video and is further from his expertise than nuclear to chemistry or math
im not talking about disliking the videos so that I dont see see (not that it would work if big nuclear can pay YT to shove this onto my screen), I mean getting this shit taken down if he doesnt stop. this isnt about NileRed (I dont give a shit about him) but T.Fs practises which either should change or get him banned


also, does this fucker even do any work? senior role nuclear power plant or something, its so obvious, also cringe, that he gets the role just to have 6 days of free time a week to do whatever, on a salary. the industry hiring safety sticklers and weewa safety bois that you wouldnt want to be around in real life, just to get him out of the building and make sure that if people see him, it is a bad thing. not to mention how he is a stickler for safety - which, nuclear - OBVIOUSLY the safest thing in the world, could do no wrong - wants to dickride

I dont want to simply report all of his videos because that will just lower MY weight on the actions that I might take against his channel in the future. I would rather plan it out and so I am looking for ideas or movement

It wouldn't look like anything. It would be too small to measure even.

The reason things have a "look" when you look at them is because they reflect or emit light, which is not something a singularity can do. If you take away the event horizon and the black hole surrounding the singularity, then it would be completely invisible.

Panspermia is unironically their best shot because life is completely alien to the material reductionist position. There could be a chemistry out there unlike anything that is known which makes life more likely. But it isn't merely panspermia. It is some alien race came from panspermia and with its knowledge created at least a second-order life which mimics their chemistry in the terms of the proteins in terrestrial life.
You will have a hard time finding them admitting to this because it is bad optics.

Anyone else think the "stay in school" genes actually have nothing to do with intelligence or IQ whatsoever? They keep being touted in genome wide association studies as proxies for intelligence, which I feel is horseshit. If anything most of these genes probably have something to do with emotional regulation or lower anxiety levels, where someone can stay inactive at a desk like an NPC and not be attacked with existential thoughts or feel like they need more physical activity. Basically the stay in school genes are actually NPC letzte mensch genes where you're less likely to feel anything. I personally ran my own autosomal file through the GWAS study Ed Dutton and Michael Woodly used to gauge the intelligence of ancient Romans and came "below average" in both polygenic intelligence and years of schooling even though I came 98th percentile on my country's version of the SATs, have a confirmed IQ of 140 on an in person test, got into an accelerated learning program through a standardised test and my dad is an ex Uni lecturer, so I frankly think the entire field is mostly statistical pseudoscience ATP

This is me. This is why I have so many fields of study under my belt, I (have) literally attend lectures while reading papers on entirely different fields, between gym sessions or video game matches or shitposts or writting papers in my head and psychically throwing them at the world. Im the "Last Ubermensch". Im not a playable character, as natural clones of everyone exist but not me specifically, as my clones are untermensch like everyone else.

Its not entirely "Gene" related, the part that is isnt relevent to this or you in any way. You have a materialist mindset, a focus on chemical chains inside of you that determine who you are...its a sickness that festers itself into malaise. That mindset limits you and becomes a self fulfilling prophecy of learned (conditioned) helplessness.

Stop being easy on yourself, externalizing resposibility IS the easy path...and one that will leave you empty and broken...and that is beneficial to idiotic Psychopaths who enjoy electrocuting peculiar little kids.

Mostly from nurses, as the doctors have a more rigorous labor to attend to, but not always. M.D. requires a certain level of Sociopathy that can be a kind of "dark attactor" energy source.

The apathy to suffering was very apparent across the board though. Too many fakers not punished and now the genuine are ignored outright.

Empathy to the disgenuine is a later crime against the innocent.
