Zhang said that the first ps2 is the most pathetic thing I've ever had a good MPU. I really like the video game pickup videos though if I could make a suggestion, the missions were pretty repetitive, and the baby boom was considered to have ended in the industry? I mean sine boy not sand nigger even though he just dumb how to save ted Kennedy, the missions were pretty repetitive, you ask me know when you're stuck in traffic on the board and the site but it wasn't until now that i can get a disk version of the best case scenario for my entertainment and worst things about 4chan minutes ago and now it's in really high demand and the lowest pRice you can understan and worst things about 4chan minutes ago, and valve's steam summer of them are ones you probably know as regulars others are for the sole purpose is a streaming pile of the best and worst things about 4chan.

How many of you guys have skype?

I was pondering inviting people to a 'science chat', where people interested in various scientific things could be invited to talk about general sciency stuff. Then maybe later, we can split it up into hard-science and soft-science. Even later, maybe we can make chats about specific sciences, like one for psychology, one for biology and so on.

What do you think?

Quick Rant
I hate how they always portray humans as violent barbarians compared to the peaceful advanced aliens in movies, on the internet, etc. From everything we know about life, intelligent species are almost always predators, because it requires thinking, whereas prey just have to run. To become the dominant species on their planet, they have to be the apex predator, like us. Killing is a part of life and I think it's safe to say any other intelligent life out there is very similar to us in terms of violence. Thoughts?
#2084 to #2054 - thedeadpidgeon (06/17/2014) [-]
I know I'm late to this, (been out for the weekend) but I just wanted to give my two cents. Science fiction isn't about giving us an idea of actual possible real world scenarios. Like most narratives, it's main purpose is to create a commentary on the world as it exists. When people want to make a literary statement pertaining to the meaningless (although not without evolutionary benefits) violence we enact as humans, an effective way of doing so is creating a peaceful race as a foil to our species. In fantasy it's elves and in scifi it's aliens. It's not because we actually believe that aliens would be more peaceful. It's just a useful plot device.
User avatar #2063 to #2054 - nigeltheoutlaw ONLINE (06/14/2014) [-]
Copy paste from your other comment on this topic:

Not necessarily. There have been a lot of interesting scenarios postulated by people smarter than me about world ecosystems governed by other forces than "me eat other things" like interspecies cooperation and resource exploitation. These would produce species that could still be sapient, but wouldn't necessitate violence or even predation to be the apex species. Appluing what we know about Earth's ecology to the whole universe of possibilities is naive.
User avatar #2062 to #2054 - revengeforfreeze (06/14/2014) [-]
I agree with you. But. Say that we have different chemicals. Different chemicals may make us require different nutrients, so MAYBE, there are animals evolved to be vegetarians on other planets. I doubt they'd be completely peaceful though, since they'd most likely have cognition just as us with violence, anger, hatred, fear and so on.

Quantum teleportation


A couple of weeks ago, it was reported that scientists managed to achieve this. MY two questions are these:
Hes it been debunked? This question is the important one (yes or no will suffice)
What kind of equipment was used? (Just short about the technology, if anyone knows this)

The experiment was performed at 10 feet, I believe, so I know it's not definite.
User avatar #2042 to #2032 - xsnowshark (06/13/2014) [-]
Anything quantum is going to involve a high degree of speculation. It could have happened, or it possibly didn't happen and their equipment gave them incorrect readings.

I think it needs to be repeated a few times before they go announcing things like teleportation.

If you want to read something interesting that has actually been proven and happens on the reg' look at quantum tunneling. It's very fascinating.

Hello science board. I have a fairly large request.

Can one of you prove the last lane, using the two first ones, and post every step of it in an easily readable picture?

I'm planning on using this in the presentation part of my oral exam tomorrow.
User avatar #2045 to #2010 - whatley ONLINE (06/13/2014) [-]
Unless I'm being an idiot and missing something I'm pretty sure you can't?

I tried solving for v like the guy below said and I can't get two different separate terms which add like the ones in the picture, if you try doing it by solving for v then the c's cancel and you just end up with a single term.

Whatever I do I always end up with E^2 = P^2 x c^4 / v^2

User avatar #2046 to #2045 - rainbowrush ONLINE (06/13/2014) [-]
It's np. My exam is over, and it's not something hard, I just didn't have the time to make it.
User avatar #2047 to #2046 - whatley ONLINE (06/13/2014) [-]
Oh well, just don't know what I'm missing here, doesn't look like it's a super complicated rearrangement.
User avatar #2055 to #2047 - xsnowshark (06/14/2014) [-]
I agree, I'm really pissed that I didn't see it, haha.

User avatar #2056 to #2055 - whatley ONLINE (06/14/2014) [-]
Yeah, nothing really seems to work. I went with the simplest looking way and just made each equation equal to sqrt(1-(v/c)^2) and then equated them into one equation, but there's just no way to get separate terms really.
User avatar #2057 to #2056 - xsnowshark (06/14/2014) [-]
I thought about doing that, but having both P and E in the denominator doesn't work.

Plus you need to eliminate V since the final answer doesn't include that variable. That's why I was setting one side equal to it and then subbing in for it in the other
User avatar #2040 to #2010 - xsnowshark (06/13/2014) [-]
You definitely solve for "v". I solved the right equation for V and then tried to replace V in the left equation, but it got really messy and I need to go to bed, haha.

I'm sure I'm just not seeing some easy little part of it, I'll look at it again tomorrow.

Did you manage to figure it out?
#2003 - venomousvalentine ONLINE (06/12/2014) [-]
I was thinking about physics and shit and about entropy and the supposed eventual heat death of the universe.

I'm not very informed on all this or intelligent and google only takes a man so far.

Say the ultimate loss of energy were achieved. Max entropy, the universe is void of any thermodynamic energy.
Would atoms decay too? Is energy required for atoms to bind together and for electrons to whiz about outside the nucleus?
User avatar #2025 to #2003 - Mortuus ONLINE (06/12/2014) [-]
By the time that maximum entropy was achieved, every star capable of forming into a black hole will have done so, eventually forming into a singularity, which would condense everything into one infinitesimally small area, leading to a massive release of energy that would renew the process. Or at least, that's how I understand the final stages of the big crunch.
User avatar #2034 to #2025 - xsnowshark (06/13/2014) [-]
I have heard entropy brought up more times on this site than in my thermodynamics class. . .

Not sure why everyone is so fascinated with it, there are much more interesting topics to look into in physics.

What is it about?
#2041 to #2039 - venomousvalentine ONLINE (06/13/2014) [-]
These are spoilers
This alien creature called kyubey was sent by his species to stop the inevitable loss of energy in the universe by using methods of harnessing the emotions of teenaged girls (the specific humans at the specific point in their life where they express the most emotion powered by hormones). So he grants them a wish so long as they become a "Magical girl" in which he rips out their soul and puts it in a gem and forces them to fight witches. When a magical girl is too full of despair or they use too much magic the soul gem explodes, they die (And become a witch themselves) and the energy from that is harnessed to give energy to all the other sentient races in the universe.

But I guess its good that people are getting interested in it.
User avatar #2044 to #2043 - Mortuus ONLINE (06/13/2014) [-]
Not gonna argue with people getting interesting in science, but I agree with you.
#2005 to #2003 - thedeadpidgeon (06/12/2014) [-]
Well, If the idea that all things are made from the same basic components is correct, then I suppose atoms would break up into electrons and shit, they'd break up into quarks, and the cycle would continue until everything was broken down to the simplest possible form.
The way I understand it though, it's not a loss of energy, it's just spread out more and more to the point that there's just this expanse almost-but-not-quite nothing. Could be wrong though.
User avatar #2004 to #2003 - nebuchadnezzaurus (06/12/2014) [-]
A good question actually, I've never thought about it myself until now. Well since atoms do require some kind of energy to hold together, I'd say they would break down into components which would just be stationary.
User avatar #1991 - ilovehue (06/11/2014) [-]
what would happen to Earth if it became hollow and lost, say, 20 percent of its mass gradually, but the surface remained intact? Like, intense sci-fi mining of the mantle, and they somehow manage to gradually implant structures in the mantle. Suppose it doesn't collapse.

Would Earth's orbit change? would it impact on the moon? the atmosphere?
User avatar #2082 to #2079 - newvein (06/16/2014) [-]
But I doubt we have sufficient means at this point to mine that far down just to extract minerals that need to have the water to be further sepparated .

We would die due to the lack of an iron core. Our atmosphere would fade away and the sun would turn earth into little more than a hot, dead, rock.
#1998 to #1991 - thedeadpidgeon (06/12/2014) [-]
What are people doing with the mas when they take it out of the core? If the mass leaves the core, but remains a part of the Earth, I don't believe it should have an effect gravitationally, but the atmosphere would definitely change a lot, because the air would be pulled into the core. This would kill everyone on the surface cause no oxygen + no protection from sun and shit. There's also a bunch of other things the core affects. I think the magnetic field would be changed somehow. Is this for your book? Realize that it doesn't necessarily need to be scientifically accurate. I mean, if you hollow out the Earth and it doesn't collapse the ship of scientific accuracy has already gone tbh. The importance of scifi is usually more about the commentary it has on life as we know it, than giving us an idea of life as it could be.

it is part of a story yes but for an hypothetic game. I need an excuse for insane big underground caves.
#2009 to #2006 - thedeadpidgeon (06/12/2014) [-]
You could have underground caves without hollowing out the Earth completely. Just keep in mind that the deeper you go, the more heat resistant your species needs to be, or the more effective your cooling systems need to be. is this a story about a people who evolved underground or being driven to dig cuz of post apocalyptic world? Also? Is this supposed to be Earth or just an Earth like planet?

Oh! and if you do get deep enough the people could probably find a way to harness the heat for energy.
#2011 to #2009 - ilovehue (06/12/2014) [-]
It is planet Earth. This ball would represent the empty space. the holes represent huge pillars (imagine there's way more holes/pillars) that are connected to the crust.

This whole idea's been developping in my mind for a while, I considered the heat factor and looked up earth mantle facts, also heat collection
#2013 to #2011 - thedeadpidgeon (06/12/2014) [-]
Well if you're actually making it hollow like that, then You'd definitely need to stretch the bounds of science. When you say hypothetical game do you mnean like dnd?
User avatar #2014 to #2013 - ilovehue (06/12/2014) [-]
No, a video game. But it was agreed it would make for a good role-play game universe, such as gurps. I don't wanna spoil too much concepts here, but I think the lore I'm developing will end up being really great.
#2015 to #2014 - thedeadpidgeon (06/12/2014) [-]
Well if you plan on doing heat collection, then there needs to be something at the core to make heat. You could always just put a giant reactor there.... More importantly, Are they just going to be living on the other side of the mantle or something? maybe in the pillars? And most importantly, is this a game you might actually think about getting published?
#2016 to #2015 - ilovehue (06/12/2014) [-]
the heat collection might be huge heat conducting rods/probes, I'll find something.
#2017 to #2016 - thedeadpidgeon (06/12/2014) [-]
OHHHHHH! that makes so much more sense. I thought you were talking about leaving earth as a hollow shell. The biggest problems this would have in real world physics is the structural integrity of the hollow layer, and the way the earth would react when it comes to things like plate tectonics and volcanoes, but if this is for a video game you most certainly don't have to use real world physics so... I think it makes for a cool concept.

Still is this a plan for an actual game or just a school project or something?
#2018 to #2017 - thedeadpidgeon (06/12/2014) [-]

Like I said. seismic shit would be screwed up using real world physics, but when playing a game people care more about the story and gameplay than accuracy with real world physics. It's believable enough that the contradictions shouldn't be a distraction.
User avatar #2030 to #2029 - ilovehue (06/12/2014) [-]
nah, tectonic movement must be taken in account...
#2031 to #2030 - thedeadpidgeon (06/12/2014) [-]
Well I'm not an expert in it, so I can't tell you everything you need to know. I doubt that there's a seismologyxplain though. my biggest concern is thath there are many things in the mantle shifting around, and the gap in the mantle will probably screw that up. especially on major fault lines. Can't really tell you much about what might happen though...
User avatar #2027 to #2018 - ilovehue (06/12/2014) [-]
haha no problem.
User avatar #2012 to #2011 - ilovehue (06/12/2014) [-]

User avatar #1996 to #1991 - xsnowshark (06/12/2014) [-]
Orbits are a function of mass and energy, so yes, I'm sure that if the Earth magically became hollow, the orbit would change.

User avatar #1993 to #1991 - ilovehue (06/11/2014) [-]
What if the Earth were Hollow? Ok, so I found this. First interesting point is, the earth atmosphere would be shared with this new room, if the matter leaves the earth. so I guess it would get thinner. So 20% mass is a ridiculous amount, unless the miners just don't give a fuck. Let's say... erm.. 7%..
