That exact point is the heart of this debate. Does the universe have enough velocity to "escape"? If it does, it goes on forever, if not in crashes back in on itself. it also might have the exact right amount to enter a stable orbit and remain at the same size.
Think of it this way, the thing that is slowing down the expansion of the universe is the gravity within the universe pulling inwards. If there's enough gravity to overcome the energy of the big-bang....the big crunch happens. However since gravity decreases as the universe expande (because of the inverse square stuff) if the univers gets too large there's a point where it's graivty is no longer sufficient to turn expansion around. (And yes there's this the theory of the "sweet spot" where the energy and the mass are perectly ballanced and the universe stops expanding but fails to colapse. The rate of expansion IS decreasing, the question is will that be enough to cause the crunsh or not because the rate of decrease (second derivitie of velocity) is decreasing as well.
Yeah but how long will it take someone too compare a couple of files that differ by onyl the Global Release Indentifier and write a 300KB program that strips out the unique number and replaces it with random garbage? Then if some gets told they a file sold to them appears they just have to point out that someone else took a copy ran this utility and it put in their number. Problem solved, unless the RIAA can PROVE that it is their file, then the perosn isn't guilty.
This was orignally done. In fact it it was Bill him self that change this. He went to IBM to sell them DOS and then told them he wouldn't sell it to them, he would LICENCE it to them, one copy at a time. The look on the IBM people's faces must have been classic, to them this was something totally new. Today it's the standard..... While I don't like it, i have to agree that if software was something you could "buy" and "own" you would see the price sky-rocket. Dell would "buy" windows and install it on all their PCs. That's great for them, but then if Joe Home-User wants to up grade, he either needs to find someone with install files, or go pay the same to buy them as dell would. Dell can pay Millions for those files, can joe-user? I'm not sure what the best solution would be, but i'm pretty sure it's not what we have, and it's not out-right buying software. Here's to hoping the when MS has to lower their prices to compete wiht Open Source they realize that if a windows disk cost $45 and not $200 people will go buy them (and if it's less more people will buy them). I'm not trying to justify piracy by saying that stuff it too expensive, but I am saying that currently alot of "everyday" software is prohibitivly expensive. If it was $150 to upgrade the Windows OSes on all 3 of my machines I would go do it, at $600 it's just not gunna happen. I know that alot of the crowd here is probably not of that mentality, but i would bet that alot of home users are.
Yeah hydrogen IS the fule of the future, however in cars and stuff you have air to use in the reaction. In rockets and in space you need to supply the Oxygen for it as well. So you mix the two.....H2O2....wait....it's hydrogen peroxide........:)
Because the peroxide will evaporate faster then the water. This leaves you with a very nice mixture of hydrogen gas and Oxygen. Which is why it's such a great propelent....however this also means you have a great chance of blowing up the rooms your working in, and they only liquid you are left with is water......
Not only that, it gets totally white, like snow, and the skin feels somewhat strange (rough). And I'm not talking about wound here, but healthy skin!
Um....you do realize that you are KILLING the cells. This is cleaning out the wound to prevent infection but it's also making it worse and oreventing good healing. There's a reason most people buy the 3%. The 30% stuff if usually for when people have large areas (like burns) and they mix that with water to make a LOT of mixture for soaking in. Using that stuff straight up is NOT a good idea.
dude, obovously there would STILL be OSHA laws...
However even those aside...ALSO companies are responsible financialy for any injuries that occur, so they would want as few injuries/deaths as possible. Also, if one company has a MUCH higher success rate then another, which would you book your space travel with? Remember Volvo has often by WAY ahead of any laws about safty, and they are not the cheapest cars, and they still sell VERY well. To companies the cost of an accident will be a driving force to prevent them, after all you have many and your company goes under.
The Real answer, The US government needs to aloow corporations to go into space. If space travel/explpration is privitized, then you will see industry finding a way to do it cheaply and safely. After all the possibilites of "vacations" in space (that don't cost $20 mill) of having companies put research facilities in space or on the moon and the HUGH range of other things that could be of benifit to industries (current and future). Also, if there is compition then these companies will find ways to make the trip cheaper (but they will always focus on safty because they (unlike the US gov.) can't afford have employees die (NOTE I AM NOT SAYING THAT NASA JUST "LET" THIS ACCIDENT HAPPEN....just that the gov't doesn't have the same finincial pressure to make sure that employees are safe taht most companies do)). The future of space exploration/travel/and experementation SHOULD be with the private sector, not the Gov't. Not to mention toat most corporations tend to work together better then most gov'ts. :)
Because any observation would change the data on both the sending and recieving end, and when you re-transmittied it the sender would know. Look at it they way, the data is sent as a sieries of pulses that have 2 possible states, yet at the time of transmission they contain BOTH states. It's not until reception that they decode into one state, this decode can be detected by the sender by the change in the state of his transmission. and can instatly stop transmitting. The intorceptor would get 1 bybe 2 BITS of data before the signal is killed. That's the power here, is that there's nothing for them to decode, because they sender stops very quickly after the data is intercepted. For more details on how this intrusion would be detected I would recomend reading a book on quantum computing which will dedicate at least a chapter or two to this (more then I care to put here).
:)
I understood it, i was just offinging more ways that this method of copy protection sucks. Oh wait that's right replies are supposed to just be echos of the original post, we can't have any original thoughts here now can we?
Or you use the RCA in on your TV for the VCR. The VCR can pass though another device, the DVD player cannot. You know nice it would be if the DVD player had a "line in" like the VCR. Then I could easily hook the two of them in a chained configuration that I want without running into copy protection. Oh wait that would require about $2 worth of extra hardware on the DVD player, can't eat into those profit margins....
1) Burn of CDs/DVDs of important data.
2) Put CDs/DVDs in plastic ziplock bag
3) Put in another in plastic ziplock bag
4) Put in Freezer.
5) Data is safe.
better then 95% of the time the contents of your standard home freezer are undamaged after a fire. Data back up isn't that hard, beside most/.er could always just re-download their porn later:)
The information being transmitted is the color. Let my try and explain. You have 2 qubit-jelly beans. A qu-bit jeally bean can either be red OR green. Now we will use this as we would normal qubits and say that the two qubit-jelly beans HAVE to have the same color as eachj other because of how they were created. NOONE looks at them, they are in sealed boxes and takes to vary distant points. At this point they are BOTH red and green at the sametime. It's not until one of the carriers opens his box and looks and sees that his is green that either has a definite color. Once he does this the other one INSTANTLY is also green. That information about the color was transmitted INSTANTLY from one qubit-jelly bean to the other. That's the information transmitted.:) I know it sounds like it wasn't information, but in quantum mechanics it is because neither one knows which color it is until they are looked at.
Is that this technology whould have more immediate effect on computing. This is an important step towards quantum computing. Why does the media focus on the sensationalized possible outcome (beaming people) and not the less glitzy, but HUGH impact of what this means to computing. This would revolutionize computing the way the transistor did.
You are thinking in classical terms, remember that the laws of classical physics don't hold true for the quantum world. Schrodenger's cat is NOT eitehr alive or dead, it's BOTH until we observe it. This is the main reasont that quantum mechanics is so difficult for people to understand. Remember taht schrodeinger's equation gives us probable locations for an electrons in a potential well, and it has equal probibilites of being on either side, and in fast spends 1/2 it's time in each, however it never crosses the middle. We cannot observe the fact taht it crosses because in observing it you lock the electron on the side you found it. The problem with all the examples of the quantum world is that people get so hung up with the cat's and the jelly beans that they apply their practical everyday common sence to these examples, and that doesn't work becasue these quantum cats adn quantum jelly beans do not follow the laws of physics as we can observer real cats and real jelly beans doing. This realm is one of the coolest places in physics because it has it's own special rules that change when you look at them.:)
That's not true in the quantum world. In the quantum world the jelly beans don't know which color they are, in fact they are BOTH colors. It's not until they are actually exaimned that they decide which color they are and retoractivly enact that policy. This is the idea behind quantum encryption. The act of reading the key changes it, therefor if anyone taps into the signal, and reads it, both parties (sender and reciever) know that the line has been comprimised. If your still confused I would recommend a book on quantum computing. Most will give a HUGH description on this, more then I care to give here. The man thing to remember is that the Jelly Beans are qubits....not jelly beans. Therefore your assumptions about jelly beans don't hold true.
Yeah, it scatters it like a billiard ball hit by a spitball. Remember there is VERY little movement by the electron for each photon. Infact to prove this theory they had to use a laser beam of LOTS of photons to move an electron very much at all. When they can do this with an electron i'll be much more impressed, espeically considering that the photon has no electro-magnetic charge and much of their process could be greatly disturbed byt charges. Then again you have to start somewhere and moving photons is a good places.
Wait for someone to invent a really useful device that would sell more of the media company's product, sue them out of existance, then release their own copy of said invention. They can't just appreciate that someone is helping them get to a larger audience.....
Why do i suddenly have this image of the Ned Flanders and the boys trying to watch a cleaned-up version of Pulp Fiction?
Exactly, the more you use it on the docking cradle, never taking it off the quicker the battery will die. If you use in on the wall ALL the time, then you should make sure that at least 2x a week you let it toally drain and totally recharge (pwered off for this recharge). Batteries needed to be worked out to keep there condition....oh wait, this is/. no one here knows anything about working out;)
My experience with the state do-not call list was pretty poor. SO i just switched my "listed" nuber to my cell phone. It's the only number I give out to ANYONE that I don't know. Now if i get a telemarketer call it's on my cell. I politly inform them that this is a cell phone, and as such illegal for them to call. I ask them for their address, and the id number of this call that I may send them a bill for the charges to my cell phone for this call, which they are now legaly liable for. I get supprisingly few calls now.:)
Yeah, at least when we made them at college we used PCV pipe parts, a grill ignort button, and an LP gas tank. Come on if your gunna make one, make a relly fun one. Nothing like cooking and shooting the potato at the same time.
