It always bothers me that, according to the laws as we understand them today, it takes a computing machine an infinite number of logical operations to figure out what goes on in no matter how tiny a region of space, and no matter how tiny a region of time. How can all that be going on in that tiny space? Why should it take an infinite amount of logic to figure out what one tiny piece of space/time is going to do? So I have often made the hypothesis that ultimately physics will not require a mathematical statement, that in the end the machinery will be revealed, and the laws will turn out to be simple, like the chequer board with all its apparent complexities.

Quantum Information Teleported Between Distant Atoms

For the past few years, I have been following the buzz on quantum computing. Even if I only barely understand the theory behind physics involved, there is still something mysterious about quantum mechanics that keeps bringing me back. Anyway, I diverge here.

Recent breakthrough in quantum computing occurred when scientists were able to successfully teleport information between two distant atoms. Furthermore, there are huge possibilities in the field of quantum cryptography if the efficiency of the quantum entanglement is a little more feasible.

Refer to the original article below for more information.

Science Quantum Information Teleported Between Distant Atoms.

Physics’ sharpest mind since Einstein

Here’s an article that talks about Ed Witten’s work. I had no clue about him before this but i see that many people have acknowledged his invaluable contributions to Super String Theory. I guess, that does make him to be one big shots in Physics during our time.

I linked previously to Dr. Michio Kaku. His site is loaded with information on Theoretical physics. Here is a comment that he made on Ed Mitten. (An excerpt from the article)

“I do believe there really is a category for a genius who is a supernova — a supernova that lights up the entire scientific landscape and that is Ed Witten,” said theoretical physicist Michio Kaku, the author of “Parallel Worlds and Hyperspace.”

“I think he is as close as you are going to get to a living Albert Einstein today.”

That is so freaking cool. When people compare him with Einstein, i feel guilty of not knowing about a person of such significance. Shame on me …

Here i am, off to go read more on him and work on my research some more 🙂

Update : Found some more stories and interesting posts on the same subject. One over at Kuro5hin and some posts by physicists at their blogs – Peter Woit and Lubos Motl. Both have interesting opinions and comments. Read on.

A User’s Guide to Time Travel

Whoopy doo. I almost have a Time Machine in my hands !

Now if only i can just create a blackhole and get a computer with a mega huge cpu power to solve a billion variables accurately, i will be done …

Now read on about “A User’s Guide to Time Travel” – All it takes is a grasp of theoretical physics, control of the space-time continuum, and maybe a ball of cosmic string.

A very interesting and captivating article about some of the theories and concepts you need to know before trying to even talk about time travel to anyone ! Definitely a nice lay-man’s intro to the subject …

Also, here is the author’s site. Dr. Michio Kaku is the co-founder of String Field Theory. If you have never had the chance to read anything on Field theory, then believe me, after the basic reading i’ve done, i’d salute him a 100 times ! He’s got a great site going on, full of technical information. A nice site if you like theoretical physics and many other scientific phenomena.

Update : Saw this article “Realistic Time Machine? New design could forgo exotic ingredient” and found it interesting and relevant to the topic. While all the suggested theories seem good, nothing can be commented about them until a practical model is developed.

— This is so freaky cool. Just finished reading the e-book from the site and it was definitely worth the read. It has a different perspective of looking at the events relative to the other books i read before. Nice. Worth spending the time on a saturday morning, i am sure !
