• ### How do you solve the absolute value inequality: | 2x + 1 | < | 3x - 2 | ?

How do you solve the absolute value inequality: | 2x + 1 | < | 3x - 2 | ??? I'm learning absolute value inequalities for my math course, and was asked to solve this inequality. I'm confused because it has two absolute values. Can someone please help me out? I'd really appreciate it. Thanks in advance.

• ### What are dimensions? Really Physically what are they?

I know from what I have learnt there is 10 dimension and we live in a 3 dimensional world I am not sure if I am right but you get what I mean.

But what I want to know is what are dimensions physically, Where are they I don't understand, Yes I understand we have 3 dimensions we can see in our universe x,y,y then a forth time, But what are they physically. When people say dimensions curl over each other to look the same as other dimensions as the we could live in a 1 dimensional world but its so curled up that it looks 3 dimensional. What is curled up, the universe its self? All I want to know is where are these dimension's like the tenth dimension, Are they outside the universe? or they in subatomic particles, When people say dimensions can be curled over to travel to different dimensions what exactly would be curled over? I know basicly what dimensions are but where are they, Where are they found? Like can we find the 5th dimention thanks

• ### Can quantum computing create artificial consciousness?

Quantum mechanics is what gives us humans free will. The fact that our world is probabilistic, explains why a human's choice is not predetermined. Let me explain. If our world was deterministic, with enough data on how every particle in your body moves, it would be possible to know what somebody is going to do before they do it. However,... show more

If our world was deterministic, with enough data on how every particle in your body moves, it would be possible to know what somebody is going to do before they do it. However, uncertainty allows us to make decisions which are not already determined, giving us free will. My question is, would the same apply to artificial intelligence? If AI ran off a standard computer, it could only do what it is programmed to do. But if it ran off a quantum computer, wouldn't the uncertainty allow the AI to make probabilistic decisions? If the decisions of an AI were not deterministic, wouldn't that give it some sort of free will?

• ### Equation to find the time for an object to fall to the Sun from the distance of Earth's orbit?

I've tried some sites with on-line calculators but they all assume a steady acceleration. An object falling to the Sun would accelerate faster as the gravitational pull increased. If you know of a site for this it would be great. PhotonX: You know that "g" changes constantly as the object approaches the Sun. At 1/2 the distance, g... show more

If you know of a site for this it would be great. PhotonX: You know that "g" changes constantly as the object approaches the Sun. At 1/2 the distance, g increases by 4. I think your formula is only for negligible distances where the acceleration does not change appreciably. An on-line site to calculate would be nice.

Please, if you are simply going to just post hate comments or give me the "go educate yourself" kind of answers then I beg you to spare me, I truly want to understand this problem I don't want to argue, I'm not here to prove god or disprove him its just something that came to my mind when reading about it and did not find anyone who gave me an actual answer. I just posted this in the religion section thinking it would get more attention since most people I ask this question to relate this to god somehow, and I got barraged by hate comments so believe you me I already had my share of that so please answer this "rationally". Since some scientists proved that the universe is flat with 0 total energy, that would indicate that it requires no condition at all to exist, then what is stopping universes from popping up literally everywhere and every time? To elaborate on this, if we drop a pen it will fall, what kept it from hovering in the air? gravity. what if there was no gravity? it must hover unless something else pulls it down or push it towards the ground. What if there is nothing whatsoever pushing and pulling the pen, gravity or anything else... yet the pen falls to the ground, would that make any sense? So how is it then that universe which require nothing at all do not pop up right now just where you are sitting? isn't that enough proof that the universe did not come from nothing? I am very sorry please bare with me, I dont see how multiple universes can solve this, our universe whether its alone or one in a billion, it came from nothing, then why does not new infinite universes pop up inside our universe? Here is professor lawrence krauss talking about this issue: http://www.youtube.com/watch?v=veU6hK3jM... He starts explaining the "flat" universe in around 6mins in. I would appreciate it if Mr. Villager can elaborate on how can something can come from nothing "0" yet requires conditions, and why would that condition be "no pre-existing universe" I am not asking for facts, I would be content with a theoretical answer.

• ### Are there other sense we know of that humans don't have?

I mean, I, obviously, know of the five senses humans have, but do we know of senses we don't have, that we - humans, animals, insects - don't have? I'm wondering about this because I'm coming up with an idea of a story other intelligent life in our universe who have come across one of our Voyager spacecrafts, and I'd like to delve into this civilization and make it as different as I can from us. I probably should have added that I mean senses we don't know of any creature having, which includes snakes and sharks. And by senses, I mean senses that we use all the time and know we use, like the 5 senses, not the other sixth senses that no one actually can notice themselves using, like the smelling of another's emotions. Anyways, I guess what I'm asking is if there are any fictional - for lack of a better word - senses, but by fictional I mean types of sense we, ourselves, can comprehend, and that scientists have discovered, but not from any animal. Actually, I wouldn't mind learning about senses or abilities that certain organisms have, like extremophiles, who don't need the sun to survive.

Writing a new version of another question since I did not get the question right. Please, since English is my second language I hope you can disregard any spelling errors. I do not have a mathematical talent, at all. I do have a creative and logical mind though. I have thought about the "string theory" or "M-theory" a lot and got this thought. Do any of you have any thoughts about this? It is only thoughts and probably a wild guess scientificly but here goes: Mass creates a gravitational pull, and as the mass becomes greater and/or more dense, the gravitational pull gets stronger. It then pulls smaller portions of mass towards it and/or depending on speed and trajectory of portion pulls it into an orbit. Now if we start from the atom and scale up we see protons, neutrons and electrons (not having included antimatter or other..) and another step and we see quarks..and so on until we find the strings that are the final step. Now for my thoughts. The strings are folds in space-time that vibrate and thus (in a yet unknown way) creates matter... thus we are all vibrations of nothing. The folds might create the gravitational pull with the folding itself... like a piece of cloth that you pinch and make a small fold... anything on it will move towards the fold. And the more mass, the more strings and folds... the more gravitational pull. Since I have not studied this in any way (meaning: learned mathematical fomulas and rules about the area in astrophysics that it concerns) I hope you read this as written by the layman that I am. And yes I do know there are more advanced ways to describe what I wrote... but i did not want to write for hours :D
