So if there was negative mass or a method of warping space artificially, why would that move a ship forward? Wouldn't the "wave" behind the ship also create a proportionally deep well in front of the ship with an "upwards" slope the ship would then have to overcome with the same amount of energy? That seems like you'd end up not moving at all no matter how severe a warp you created.

Hey /sci/ I have a question regarding viruses and the immunity of them. Specifically in question of the ebola virus, I ask you: Can willpower carry into a person developing an immunity to a virus or disease? I know, as healthy as I am now, I can talk smack, but is it entirely possible that in the midst of my body fighting the disease, that if I just hang on, I will naturally purge myself of it?

https://www.youtube.com/watch?v=dA_vynxUaao&list=UUnOAynBmYKA1neozHQNF0mA Non engineer spic here. What are you thoughs on the free energy movement? What do you think of research groups as this one: http://www.energia-libre.info/ So far they seems like legit shit. They seem to be researching Nicolas Tesla papers. What do you think of the following argument: Free energy is supressed by big oil companies.

so i know that sum of forces = zero, but what is causing that when you have a mass hanging from a spring? force of a spring = kx, so some of the force of the block is being used to expand the spring (or bonds in the case of a rubber band) so would a scale read a different force with/without a spring? is there less force on the scale b/c the spring is taking some, thus making the block 'lighter'?

What's /sci/s favorite science/math movies? My favorite is A Beautiful Mind, or maybe Infinity.

okay, so i realized i keep going in this weird circle where i act the way around all the real things in my whole life wanted to react. im am disgusted with myself and who ive been. every interaction i had, every single memory makes me cringe in disgust, sheer embarrassment. theyve been whispering and force, ramify the truth down my throat, i am creepy, ugly, annoying. i know it. i know the tears shelea, all this time, its all i lie i live in this place but its nothing its a link in this super weird infinite loop why is it real why does it the exist just help me i dust dont remeber mess are rthey were there your{'. you sold them like they were nothing! when just a observer here at but livng wired to suffer the hurt from YOUR HANDS down down the parkinson what you said and all through the ages but can never told us the end happening, why is it happening just tell me hwy its all here, there has to be an explanation or els im suffering all this for no cause. (or at least one that i understand. it sounds like a lie or a joke but i get broadcasts from aleins telling me the truth, i see through your lies, your faulty and selfish and egotistical motives., i have them on my side and they tell me everything. i used to tell people and ended up in a behairoal health home for a little under two years and got out about 3 months ago, a epiphanies about death and i went inside and after t almost everyday for years i live in this ralm, discombulated from the core, i am dissassembles, i am jesus christ i am everything, the paint in the walls cant scratch me, haha! i am triumphiant, or should i say trumpet, if they weren't the nyms i remember than the pain ought to be clever! meh heh heh

Are there any properties that are typical to known prophage attachment sites in archaeal and bacterial genomes? >posting a science question at /sci

The weekly revenue of a shop is approximately normally distributed with mean $1400 and standard deviation $250. The shop must have revenue of at least $950 to be in profit for any given week. With this information, I have been asked to calculate the probability that the shop will be in profit for any given week. In simple terms, I know what my standard deviation and mean are but I'm failing to see how one would know in advance what the chances are of making a profit.

Is there some drug I can take, or some for of self-hypnosis I can execute to stop myself from swearing? It never used to be a problem but ever since I joined 4chan I can stop yelling "NIGGER" in the privacy of my own home whenever I get mildly frustrated, and since I actually sexually prefer black women and I'm going to college soon, I would really like some help.

Are there any other games that have deeper mathematical results/significance than this?

Mathematically speaking, what is a "point"?

Haven't seen one in a while. Beautiful mathematics problems, difficult integrals, nice proofs etc thread.

Is it matter which manifests mind, or is it mind which manifests matter?

How do you solve this?

>you start with a single sphere >you chop it up into pieces >you use only translation and rotation to reassemble it >you end up with TWO spheres!!! WTF MAN? Explain!

Any anatomy fags here? My wife wants me to go to a reflexologist, but it's hard for me to believe that this actually works. Can somebody validate whether this is legitimate or not please? And if there's somewhere else I should go for this sort of question I'm sorry

/sci/ if an infinitely small immovable object is hit with an infinitely small unstoppable object what happens and is it happening all the time or is there a whole lot more absolutely nothing out there than I first thought

So /sci/, I came into work today and my boss informed me that the world is fucked because the yellowstone volcano is like 2 weeks away from blowing its load. Naturally, I thought he was bullshitting or making things sound way worse than they are. After reading the news about it lately it seems like shit is kinda going down though, should we be worried? Maybe this is a retarded question but you guys seemed like the most qualified to discuss the subject. Is the world gonna be fucked over by Yellowstone in our lifetime, possibly 2014?

Tell me some interesting facts about fractals.

So i was wondering, the expansion of sin(x) Sin(x) = \sum_{n=0}^{40} (-1)^n \frac{x^{2n+1}}{(2n+1)!} is actually a polynomial, and since an x^k polynomial has kth roots, a sin(x) has infinite number of roots, seeing how the sum is from 0 to infinity. But this got me thinking. replacing the infinity with just even a 10, gives roots very approximately to integer units of pi already, as expected from the roots of sin(x). The more intriguing point is most of the roots are complex; out of 21 possible roots, only 5 are real, 2pi, pi, 0, -pi, -2pi. This made me think for quite a bit. I went to wolfram, i entered in the expansion of sin(x), set it to zero, set the sum to end at x^81, the maximum it can handle. And i got the resulting image. Image attached, all 81 roots on the complex plane. can anyone explain the shape/why the graph is so odd? is there anything interesting i can learn about the complex roots?
