The rope leading all the way down to the ground was cut and only 1 man is holding it
Since the station in orbit is in a friction less, 0-gravity Newtonian environment would it not be feasible to begin pulling on the rope eventually causing the station to be dragged back down into earth, de-orbiting it and causing it to burn up in atmosphere?
>>8120348 I'd probably say: 2 depends on the def. of 4 9 The others the appeal is the human component or the skill specialization might not be realistic (i.e. janitors, you could get a floor sweeper but random messes/hazards you'd need someone on the job).
Since /x/ is full of retards that believe in reptilians more than extraterrestrial life, I'll post this here. What would you do if we were contacted by sentient extraterrestrial life? How would the human race react? Would we send a diplomat to communicate with them and if so, who? Bonus points for sound and reasonable explanations
I've been revising some statistics lately, namely random variable distributions. My friend has given me some distributions he came up with and I'm trying to find the distributions of sum of variables etc.
He gave me 1/sqrt(1-x^2) and I'm pretty much stuck, because every way I know of doing this kind of problems leads me to an integral that wolfram doesn't even dare to touch.
Pic rel, I've tried the very standard method and ended up with integral that I have no idea how to solve and wolfram comes up with elliptic integrals. I've also... Comment too long. Click here to view the full text.
What's keeping the last down quark in the proton from decaying in the same way the down quark in the neutron decays? I imagine it might have something to do with Pauli since you'll have three up quarks with only 2 possible spin values but shouldn't the existance of color make this a non issue? They obviously all have different color.
>>8119700 Considering just the spin, a 1/2 and 3/2 state are possible, but when adding in the orbital angular momentum, there's no way to maintain that 1/2 state. I don't feel like doing the math right now.
No, the lighter state does not exist.
I did a quick calculation and found that with the amount of energy it would take to convert a mole of protons to delta++'s, you could get 37,000 kg of matter to escape velocity on earth.

Everyone knows that Aliens "fallen gods" created the human race for the purpose of a working slave species to mine gold since the beginning of our history. Gold is the best conductor and resource for them. Think of kings and rulers, why were they all so obsessed with gold?

The fact is that the MIT article is worded to come across as "If you've beaten Super Mario, you're practically a mathematician" rather than comparing the two or simply saying "Super Mario is of comparable difficulty to some complex math, if you've done the former you could probably do the latter".

I did some pointless thinking about randomness and order, how it fits in with our universe, and possible explanations on the origins of said universe. I will just post them here because I really want counter points if anyone has them... well... from people who have a better understanding.
Life was 100% destined to happen mathmatically, and, depending on the existence of a real "free will", possibly beyond.
Let me use an example:
I have a billards table and on that table I have 23 billard balls. If I hit one ball (assuming no one reaches over and interferres) it will bounce off of other balls, which will bounce off others, and so on. If I sat down and knew the exact physical properties of the environment, the balls, the force in which the initial ball moved, etc. etc. I could, with enough time and energy, calculate exactly where the balls would end up at any given moment, which balls would hit which, hard hard they would hit, and eventually even the end. I could, in fact, calculate the future as long as I hit the initial ball EXACTLY the way I calculated for. The rest, after that, would not be random.
Multiply that... keep multiplying until you give up and then some more, you now have the ability to calculate from the moment the Big Bang happened until life presented itself. Each atom bouncing around, colliding, merging, breaking, etc as physics would have dictated, eventually forming larger objects that physics would dictate and the movements and collisions that came with that. On and on. Because each was not random nor had any capability of being random. Each performed exactly the way it would be expected.
Because, assuming that any form of life has any real ability to act randomly, EVER, you could no longer calculate 100% accurately. This is not saying that any life does, but until something that is really random enters the scene you could, in theory, calculate infinitely and determine the outcomes. As long as you could calculate before hand or faster than the events. If no form of life can act randomly (what I will call "free will") you could calculate on and on until "the end".
At this moment, Earth life would... Comment too long. Click here to view the full text.
I am using this a lot, I know. I use this because, despite what we know, we BELIEVE life can act outside of predictability. We WANT life to have just one kernel of governence over its actions that is not pre-determined. Who am I to say NO? If we do then we are more special than anything that can ever be created. We have a "soul" of sorts that allows us to behave in ways unpredictable by anything else. With that comes a purpose. Not for us, perhaps, but a purpose. An event that was destined to create randomness from pure order would not be an event to take lightly, and could have very possibly happened for that exact reason. (Yes, I am touching on a creator or creators, etc. and I will at other points in this.) We could be mere scientific observations, exist to populate a multiverse (something that would not exist without randomness), simply be a dimensional random number generator.
IF Life can not be random:
So far, as far as my knowledge goes, nothing is random. We act in a way that is predictable if you take in account all of the existing variables. Therefore, I was destined to write this. Which means we follow the rules set forth by our universe, we can accomplish our same thoughts and feelings, observations and behaviors with extremely advanced AI. Which is pretty much what we are. This would go a long way in showing that we are perhaps a simulation, perhaps for an advanced being that simply wants to play with something. Life could be just the next building block on the way to randomness, or a purpose, first the big bang... then life... then [insert next step here] and so on until the purpose is achieved. The same way in which we build circuits to build devices to build software to build AI. We do as expected and eventually we will have the desired results.
>>8118979 Neural networks fall inside a family of algorithms and techniques called machine learning. There is also a more recent subset of algorithms and techniques called deep learning that focuses on a class of algorithms known as deep neural networks.
Machine learning in general is a topic that lives at the intersection of artificial intelligence and data science (depending on who you ask they will classify it as one or the other).

i think in robotics they have been using a lot of temporal difference learning which is part of reinforcement learning. if im not mistaken this is how the atlas robot from Boston dynamic robot learned to walk. (educated guess) there might be much more ways also using neural networks or combinations.
Just learned about HeLa cells online today. I've seen various figures on how many cells have been produced over time, and regardless of what that number really is, I'm just curious where all the matter for these cells come from. It seems crazy enough that cells could reproduce indefinitely, let alone where all the material comes from. I mean, if they are just simply dividing, wouldn't they get too small to be functional? Note that I only have rudimentary knowledge on biology.
>>8118624 It's a term used by creationists to create a mental barrier in the sciences that evolution can't cross. Basically: "We can't know what happened millions of years ago, so we'll use this book to tell us how it was. You don't have to worry about evolution, that doesn't apply to anything, you can throw it out." Or: "it's your way or God's way."
>>8118624 It's the creationist way of saying "you weren't there so you can't know it's true" which applies to, as just one example, carbon dating. However, the bible is still infallible. It's pretty logical.
Suppose it was possible to attach a rope from the Earth to a space station.
Would it be possible to climb said rope from the ground into outer space? I have a vague understanding of rockets needing to 'punch' through the atmosphere in order to reach outer space, but that involves flinging hundreds of tonnes of metal from Earth's gravity. If it's just a guy, climbing a rope, is it theoretically possible to slowly pass through the atmosphere?

Why the fuck are mosquitoes so attracted to me? I've spent maybe three hours outside in the past week and as you can clearly see I have suffered greatly for it. What can I do about this other than the obvious use bugspray/wear long sleeves/don't go outside? This shit isn't fair
