		<description>[...] In the shortest turnaround time for a book ever, Bora &#8220;coturnix&#8221; Zivovic (of Blog Around the Clock fame) has put together The Open Laboratory, a collection of the greatest science blogging of all time. Which is a little bit less impressive than it sounds, since science blogging hasn&#8217;t been around for that many centuries. Still, it&#8217;s a fun concept, to take all of those words on the internet and bind them between covers.

		<description>[...] I put this up elsewhere, but I like it so much that it deserves a spot here. We&#8217;ve talked about quantum computation a few times before, but how much do we really know? Metafilter, instruct thyself. Don&#8217;t forget to learn some advanced probability and computational complexity (Scott Aaronson has more). Whoa, that&#8217;s a lot o&#8217; learning, so let&#8217;s so check out the much easier, and much cooler &#8220;sleeping puppy&#8221; experiment. I can only dream that will help break quantum mechanics&#8217; association with animal abuse. Then, there&#8217;s the Free Will Theorem that just came out (some discussion on it) and another paper with a new look at an old problem. The latter describes another way of solving ye olde, super importanto Einstein-Podolsky-Rosen paradox using the relational interpretation of quantum mechanics (lots of discussion running around). Whew. We don&#8217;t need the crackpot ramblings of What the #$*! Do We Know? when we&#8217;ve got real physics to keep us up at night. So, who wants to become a physicist? (t&#8217;Hooft has some thoughts for those who want to go theoretical.) [...]</description>

		<description>Addressing Tullmejs question, I had the same reaction when I first read through it.  But, if there is no puppy, you just do 90 consecutive 1 degree rotations and observe steak.  If there is a puppy, each of the 90 times you stick the food in the box, it observes and changes the state back to a pure food state (most likely salad).  Each time, there is just a 0.0003 chance that the puppy will observe steak and therefore wake up and bark.  It all hinges on the fact that the puppy changes the state and you don't observe (and therefore change the state) between each rotation.  So, the three possible outcomes after 90 rotations: you observe salad - puppy exists, you observe steak and no bark - puppy doesn't exist, you observe steak and hear a bark - puppy exists.</description>

		<description>I believe the gravitational tidal effects, of a blackhole would prevent, the other side of the coin, thatâ€™s falling into the blackhole from being observed? The outgoing information, would always be pushed beyond your horizon, it would fall towards its creation, with the chance of it becoming a silver coin almost nil. A bit of the information of coin thatâ€™s falling in, would always remain above the horizon, until the universe came to an end. This, then would mean, the coin will have flipped and then will, slowly become real, for the coin to become real, will take a hell of a lot of evolution (which will have already happened?). The tail side of the coin will then remain beyond the horizon, until you throw in your coin, with the one only chance, of it landing heads up. To flip the coin fast enough to have knowledge of both side, would be at great risk, of a release of an enormous amount of energy. This release could be slowed down, but would eventually cause all Quantum computers to crash, with no chance of recovery.

It may be better, to put back laws of physics 100 years or start again. Better to do it now, instead of when the sun is just about to go out. Better put them back 100 years now, rather than 6,000,000,000 years later on...

Don't build a vessel and call it unsinkable.</description>

		<description>Lets take this up another gear?

Seth Lloyd:Now, Seth Lloyd of the Massachusetts Institute of Technology in the US, has used a controversial quantum model called final-state projection to try to solve the paradox. The model holds that under certain extreme circumstances â€“ such as the intense gravitational field of a black hole, objects that would ordinarily have several options for their behaviour have only one. For example, a black hole could cause a coin thrown into it to always come up "heads".

What this equates to is the Blackhole being a "CONVERSION" location?  instance if the Blackhole imposes 100% final state into the coin being "always-heads", then to gain this knowledge outside of the Blackhole, you must assert that, external to a blackhole, when one tosses a coin it should always turn up TAILS!..if one is dealing with an entangled coin that is.

Problem is that for any coin (say a dollar) that has passed through a blackhole horizon, when it emerges, it loses half its energy(one can assert that the coin no longer has energy of "two" sides, heads or tails, its either heads or either tails). The reduced state function imposed onto any entity that has trancended a blackhole horizon, may confine its state 100%, thereby trapping the knowledge of the dollar's "toss" function, but does not eradicate the fact that the dollar thrown in, may emerge as a "silver-dollar", with ist re-configured "two-state-toss" function?

In other words "Quantum -BH- Process" alows 1 dollar bits to be the input, and silver dollars 2-BITS? to be the "GAINED" output. 

I believe the information "gain" is a sublte insight on the process of initial and final state paradox?

Just think about the ordinary probability of the coin-toss?..when it comes down heads, you also know it did not come down as tails?..prior to tossing of a coin you have 50% of either, after the event you have "gained" extra knowledge, you have 100% knowldedge..cause and effect?..gaining the knowledge before the coin-toss occurs, one has to subscribe to the 'Time' re-configuration initial state principle.

Quantum Mechanics uses the re-normalization process "after" events, Relativity by its status in Space within time, always defeats QM by its processess by default.</description>

		<description>&lt;blockquote&gt;Understanding how to decode the outgoing &lt;b&gt;Hawking radiation will require researchers to weave together quantum physics and general relativity into a seamless theory of quantum gravity&lt;/b&gt; â€“ a goal that has so far proved elusive. "Until we understand quantum gravity, we're not going to be running Linux on a black hole," he jokes.&lt;/blockquote&gt;

I wonder, from a layman point of view.

If certain models were used (D brane thinking maybe, I dunno?), it  would have had to have been with understanding certain conditions were being meet? 

 "Abstractness" still needed to bring comprehension of nature's ways into the realization of the blackhole states?

 Would this have raised insight into the "new physics?" 

Like maybe "encouraging ideas" about "swimming in honey" or "molasse's special brand," as a viscosity statement, and as a way seeing dimensions and energy, travelling with infinite probability like holes, through high energy conditions?

That's the point, the model had to have been already accomplished in that unification?

		<description>so after reading the article... When using someone else's blackhole! Don't forget to squirt a little bit of duck around the rim, when you've finished. Kills 99.9% of all information, stops spacetime echos and leaves it clean and fresh for the next object to pass through.

		<description>Not so crazy after all... &lt;blockquote&gt;Quantum mechanics, looks to me like an information theory. A quantum computer sounds like how you would imagine a blackhole to work, you think there is twice as much information in there, but when you look, half of it seems to be missing. It not really missing tho, is it? It just that! Information, if it was space-time would be traveling through it self. The information would be curved back and traveling away from us, we cant see it because itâ€™s wave function is rotated(we dont see information through time we just remember what we see through space. If both wave functions are rotated into a superpostion then you are looking at whatever it was, you rememberd last). Seeing stars through time, 13 billon years ago? I donâ€™t think soâ€¦ your seeing them 13 billion years through space. No information as ever travel tho time. Time would be created by rotated information, through the surface of an un-observed space. Blackholes would not stop time but create the illusion of it&lt;/blockquote&gt;

		<description>Nice! I have little knowhow on the matter so please bear with me. One objection I didn't find in the comments is this (it's answer is probably simple, but &lt;em&gt;I&lt;/em&gt; don't get it):

At one degree rotation from salad, probability of food being considered steak is low. Ok. But how does 90 one-degree rotations add upp to 90*[that low number]; why does not probability of steak increase as we approach the (90-degree) opposite of salad? At 45 degrees, for example, have not food "arrived at" equal superposition?

It seems to me as if probability of waking pup would be very high indeed after repeatadly letting it sniff high-probability steak.

Where do I go wrong?</description>

		<description>I wonder if this is why Preskill went to quantum computation, is to learn to write the language of ingoing/outgoing state, on what existed "on" the horizon?</description>

		<description>&lt;blockquote&gt;Quantum mechanics is the coolest thing ever invented, ever.&lt;/blockquote&gt; 

I think you meant "Quantum mechanics is very very very very nearly the coolest thing ever invented, ever."

:)

		<description>I feel like I have been transported back into my quantum classes of college. Thanks for making those neurons fire again! Meanwhile, I am now expecting to need to assume a spherical cow for some sort of calculation.</description>
