Pop-scientist here, why wouldn't this reactionless warp-drive work? Assuming we can build a flywheel that can survive near light speed and have an onboard power storage that can spin it up to that speed it seems to be in full accord with Newton's laws. In case you can't read the text:
1) Telescoping link between capsules, they are free to move towards each other
2) Spherical flywheel in first capsule starts spinning. As it nears light speed from what I've heard about relativity it will start getting more massive instead of actually getting any...

It could also work without the linkage simply bouncing into each other a la Newton's cradle. I don't see the momentum issue? If the rear capsule starts moving and hits the virtually stationary front capsule it will cause the front capsule to move, this is school tier stuff.
is there any ACTUAL proof that vaccines are dangerous, more than the diseases that they stop? Please don't just list TEH SPOOKY CHEMICALS that they have. I want hard evidence, because it seems like everytime a ton of people refuse to vaccinate themselves, we have a disease outbreak that could have been easily prevented
There are study databases which have only corporate interest and grants in mind. Is it so confounded to think this cuts both ways in that corporations can control both the flow and ebb of scientific information? Vaccines make a lot of money, some people would be much poorer without them existing.
If a GPU is better at cracking passwords than a CPU, why is the left brain better at mathematics and logical thinking than the right brain? Would it make more sense to interpret maths more creatively to be able to problem solve quicker?
If any of you fellow anons are still in college pursuing math, be sure to check which books are used. I am stuck using Larson calculus 6e, let me tell you, it is complete trash. The whole book is written as though it is trying to teach calculus to someone that already knows it. You will come across terrible descriptions and explanations in each and every chapter. The word problems are a real laugh too, you are expected to just pull upper level formulas out of your ass before you can even get to work.
Tl;Dr if a class you are planning to take uses a Larson math text book,...

I completely disagree. I'm not sure about that edition, but I used that book when I was learning calculus and it gives plenty of examples and problems for you to do.
If you aren't getting it, I recommend you find a video of somebody explaining what you don't understand. Math textbooks can be hard to read sometimes.
Scientific reasons why not to be vegan? Photo related just PETA being PETA.
How well accepted in the scientific community are Danny Vendramini's theories on Neanderthal biology? I realize he's a bit of a crack-head because of his "human/ape war" theories. However, I'm just wondering about his general claims.
I don't think the scientific community pays attention to such sensationalist pseudoscience other than to point out the many claims it makes without evidence and the fact that it is not a scientific "theory" at all.
Everything museums and documentaries say about how neanderthals looked is bullshit.
Ice Age Europe was the most inhospitable period of all time for life on earth, so the idea that a pink-skinned, hairless human could survive and breed there is retarded. Also, all our facial recognition software we use on their skulls is modeled after humans, despite neanderthals being RELATED to humans, not actually being humans. Therefor, they were nothing like us, and were more like purely carnivorous, northern gorillas.
What are some cool kinds of exotic planets that you think could exist?
I know about some, like chthonic planets, ocean worlds, and that kind of stuff, but let's forget what's already known and just have some wild conjecture
If a planet with massive oceans got abundant fractures to a very great depth, and ended up having those fractures fill with water which then froze, then somehow lost water, it could have truly massive cave systems.
I struggle with trigonometry and unit circles but my finance degree needs me to get to Calculus 2.
Is there any chance for me?
Why don't we know for certain there's life on other planets? If only microbial. The recipe for life is literally just heat and liquid water, right?
If Ganymede has an icy surface and liquid underneath, which we know because of geysers, it has to be heated to keep it liquid? So there should theoretically definitely be some sort of life, right?
I've got this online class i've thrown 80 dollars into and I'm starting to fuck it up. I feel like I'm losing control of this class and I don't know if I can juggle it with my shitty retail job and other online class anymore. I just want to be able to continue my education after graduation. I didn't even get a job in my field (electrical engineering) and I've been trying to keep my spirits up, but all of this shit's coming down. I don't wanna give up but how the fuck do I deal.
I'm finally getting interviews setting up, it's taken months for people to call back, though. My area's only real industry is chemical plants, and nobody's been looking for control engineers with less than 5 years of experience.
How far were you into studying math before you realized you were retarded? Not trolling, I'm genuinely curious. I'm in the process of realizing it now.
is khan academy so popular because the visualization of concepts makes people feel like they understand it ?
I personally used it a lot for math, it's a nice slow and intuitive lesson taught by someone with nice handwriting and explains things throughly. While I don't think it should replace a real class, it's a good review and brushes up on concepts you might kind of understand but things that aren't worth asking the professor about.
it's really slow and easy so plebs think they are smart by using it. In reality it is useless because you learn almost nothing, and the guy teaching doesn't even understand it properly
Fuck me /sci/ i'm having some troubles
Basically i have a situation with a constant force being applied to a particle in contact with a rough plane. The normal contact force varies, so the frictional force increases. However, with the equation i've put in the image, this would result in the particle reversing directions. How do I fix this?
The frictional force will never be greater than the force applied to the object that it is opposing, it increases as the opposing force does until it caps out at F(max). The way of calculating it is V(object)*mu(static or kinetic). As you know, mu only varies with object material.

Quantum entanglement thread go!
1. What is the easiest way to prove that?
2. How to understand time with that theory?
3. Is this a good way to understand "paranormal"?
