So I'v worked for a company that has been researching and developing the use of rare earth metals like neodymium to create an apparatus that can draw energy from the casmir effect. I personally don't do very much of the work, but, so far, we have succeeded in doing this and we had hired a man off the streets to take credit for what we did in order to keep our budget when things went bad with the people above.
Unfortunately our street man we hired was framed for money laundering by an unknown entity that really believed he invented our equipment and is now serving the rest of his life in federal prison. This is what we expected and so now we have to repress our technology and try to spread the technology by proxy, while pretending we only succeeded in making something more efficient, but, nothing more then 100%.
I have a lot of stories so if you want me to share them, ask me anything.

I had a dream a few days ago, and it was probably the coolest dream I've ever had in my life.
Quick backstory, I have somewhat of a fear of large objects, or more specifically, the thought of how small I am in comparison to large objects (Skyscrapers, mountains, etc.) I visited NYC for my senior trip, and was very startled by all the skyscrapers there. I'm not afraid in a sudden, sharp bolt of fear thru my body sort of way, more of an overwhelming feeling. This fear has, oddly enough, makes me fascinated by the scale and size of planets and distances within our solar system and universe.
In my dream, I was in the backseat of a sedan with two or three other people, I didn’t know who they were, I couldn't tell, this part of my dream was foggy, I felt comfortable with them, and I was wrapped in a blanket. We were travelling down a secluded road in the night sky, with no light pollution when all of the sudden I looked up, and there it was, f*cking MARS right next to the moon! Now normally, irl, I'd sh*t my pants, but in the dream, I couldn't even be afraid, I was too fascinated by what I saw.
Mars was so close to us, that I could clearly make out the ice caps, Valles Marineris, and most of the surface scarring. Mind you, it was very odd to be in this blurry dream state in the car, then look up and see this image of Mars plain as day and to see all of its features in such detail.
Funny part is: It wasn't hurling towards us at a super-fast rate or anything like in a nightmare, it just hung in the sky from my perspective, however, it was apparent to me that it was heading towards us, and was going to crash into the Earth. I knew this in my gut, and I made a passing remark to the passengers in the car: "Huh, hope that isn't heading towards us." Even though I knew it was, then I pretended that it was no big deal, and looked back into the car, somehow thinking if I didn't acknowledge it, things would be fine, and the Earth would be saved. End dream. Cont . .

I can't draw worth a damn and I couldn't even draw a car to save my life, so I just made stick figures to simulate the conversation I had with the passengers. Obviously, they are not to scale. What IS to scale however, is the size and location of Mars in my dream next to The Moon.
I do have some question for you smart space doctors out there if you would answer them please:
1.) If Mars appeared this size in the sky, how far away would it be from Earth? From the Moon?
2.) Would Mars be attracted to the moon and collide with it? Or would it collide with Earth?
3.) Could it be possible for Mars to just orbit the Earth or the Moon and not crash into it?
4.) Is a situation in which Mars gets this close even theoretically possible? If so, what event would cause this to happen?
5.) If Mars were to be this close to Earth, would it cause any differences in weather patterns/ocean tides? The moon affects the Earth's tides, so surly Mars would too at this distance, right?
>>
Shameless bump, posted this on multiple websites and have to know
>>
Sorry OP, I have no answers for you.
But I have questions that have to do with what you think:
What is the probability of a fugitive planet enter in our solar system? What is the probability of collision with our planet?
Should I be concerned about this?

Let [math] F: \comp^2\to \comp^2[/math] be given by F(x,y)=(p(x,y), q(x,y)) where p and q are polynomials. Assume that the Jacobian determinant [math] p_xq_y-p_yq_x[/math] is a non-zero constant.

Interesting but expanding-earth-tier.
What I don't get is how the comet increases Earth's volume by 20%? It would have to fucking huge, not what the size of supposed crater implies.
Is Many-Worlds really the best way to understand what's going on in quantum mechanics? Taking the formalism literally seems a whole lot more conceptually palatable and far less spooky than things like action-at-a-distance, hyperplane dependency, retrocausality, macroscopic superpositions, etc etc. Why does the idea scare so many people when the alternatives are far worse?

Scare in what sense?
Might be reading you wrong here, but it looks like you are assuming that if someone doesn't hold many-worlds to be true, it must be because the idea "scares" him or her ("scares" as used by you might merely refer to something the person finds uncomfortable to consider).
But might it not also be possible that someone is perfectly comfortable considering the full implications of many-worlds, and simply finds the notion unconvincing? It is both unprovable and unfalsifiable, which, to me, makes it very difficult to care about. Might not other people have similar opinions?

Hey guys, I think that I can strengthen rule 34. Rule 34 states that if X exists, then there is porn of it. I will show that X exists IF AND ONLY IFF there is porn of it.
Proof: Suppose that X exists. Then, there is porn of it by rule 34. Now, we prove that the converse is also true. Suppose there is porn of X. Then porn of X exists. Since X is a subset of porn of X, it follows that X exists. So, we now have that X exists iff there is porn of it . QED

It would take years of continuous full time study to absorb the material in all of those books
Why are you wasting time adding to a list of books you already won't finish when you could be reading one and getting closer to your goal?
I'd bet everything I have that you don't complete a single one.

Sup /sci/, /tg/ here, I'm running a sci-fi tabletop RPG campaign and I want it to be sorta realistic.
(in case you didn't know, tabletop RPG is where nerds get together and pretend they're elves, orcs or, in this case, spaceship pilots, yes, the dungeon and dragons stuff)
General gist of the setting is
>living on earth kinda sucks now (doesn't matter why, global warming, atomic war etc.)
>humanity forced to move outside earth
>builds a few Stanford toruses
>builds a few self-sustaining colonies on mars and satellites, veeery slight terraforming
The setting happens in the space between earth and mars, it's somehow lucrative to trade resources from one place to another and it's just as lucrative to try your hand at robbing those who do, and it pays to protect valuable cargo, also asteroid mining fits somewhere in that cycle of life.
How would space battles work with a tech level only slightly ahead of ours (torpedos, not lasers)?
Feel free to rectify anything that sounds too far fetched.

If you want to do tabletop RP properly, it does matter why. No one moves to Mars without a good reason. Stopped reading there tbqh

You want to know how wars will work in like 10 years?
Here is our army of hackers. Boom, got access to the enemy spaceship's database just for enough time to print the table with their uses and hashed passwords.
Boom, cracked the hash of their system administrator's password.
Boom, tricked their computers into believing I am the system administraror.
Boom, opened all doors, dropping cargo and humans to space.
Boom, killed anyone.
Who has time for lasers when the opposing team has 10 mathematicians trying to find a way around your security.

50% pregnancies failure, so huge number that I checked it on several sources.
Is this specific to humans or true for all mamals? Are half of oviparous animals eggs not hatching for all species?

Don't forget about all the anti-masturbation people who claim that sperm is life, and that masturbating is murder, ignoring the fact that even when you ejaculate into your wife's vagina, at most one out of billions of sperms will result in life, with the rest dying.
As for your question, it is specific to humans. Humans have terrible conception rate when compared to other animals. A couple having sex for a month will only get pregnant 18% of the time, over an entire year you're still only talking 92%, ridiculous.
>>
>>8443130
"Every sperm is sacred" lol. Spermatozoa are quickly disposed if not used it, abstinence would spare none.
These pregnancy failures doesn't eliminate all anomalous embryos anyway. And it's not like most people hate trying but a bad time for the others like exclusive homosexuals
>>
>>8443130
This is a strawman. The Catholic Church is opposed to masturbation on the grounds that sex was designed for procreation and using your body in a sexual way for anything other than making children is a sin. The church believes life begins at fertilization. You might find this ridiculous but it's a completely different position than thinking sperm are humans.

Ok so I hope this is /sci/ related enough but I think it can be considered engineering, so maybe the more homosexual of users can help me here:
Will I be able to smoke DMT with a pipe like this? I know that you have to slowly vaporize that shit for it to work, and the plan is to hold a flame close to the lid to get just enough heat convection going.
Then I am not sure: should I breathe it in while still vaporizing it, or should I let ot build up inside the corpus and then take all at once?
I know that you can smoke a bottle bong in this way with hash or whatever, but its usually a bigger bottle.
Will there be enough room for the vapor from 50mg DMT in that thing or will I lose a lot from the not-quite-airtight tape structure?
Im afraid If I take hits while burning I might not "break through" and waste a bunch so...

Math Textbook Thread.
So these are the Analysis textbooks that I got from the /sci/ textbook collection.
Recommend your best Real Analysis textbooks and state why you think they're so great.
From light reading it seems that Terence Tao's the most rigorous of all but it doesn't seem appropriate for a regular Real Analysis class.
