Comment Whatever happended to the Energy principle (Score 1) 283

When i learnt Science in school, we were taught that "Energy cannot be created nor destroyed, but can be transformed from one form into another" (I know this doesn't hold true especially under Einstien's equation E = mc2), but i guess you get the point.

So if we are going to spend the energy doing "work" by travelling, then it begs the question where we would get it from all the time?
I don't think car would run just on its exhaust, if there is not external energy system,
If the scientist succeeds then he might be on a brink of discovering something we call as a "Perpetual Machine"


Supermassive Black Hole Is Thrown Out of Galaxy 167

DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a supermassive black hole being tossed out of its galaxy. According to the article, the black hole — which has a mass equivalent to one billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging."

The display is just awesome, the laptop is still going strong....:), just changed hard disk once, and the OEM hard-disk i have put in a 3.5" external hard-disk encolsure and is working fine.


Submission An artificial heart for $2000 From IIT-Kharagpur

It'll be to coronary care what Nano is to cars, say scientists at Indian Institute of Technology, Kharagpur, who have devised an
artificial heart that could save lives for just Rs 1 lakh.

The research team says trials of the prototype lab--constructed heart have been successful on small animals and the gadget is being perfected on goats. The institute has applied for permission to conduct human trials.

The Total Artificial Heart (TAH) — said to be the first such in the country — has been developed by a team of scientists at IIT-Kgp's school of medical science
and technology.

After four years of painstaking research, the scientists say their creation is better and far more affordable than the first artificial heart developed in the US, which showed a ``high rate failure'' and at Rs 30 lakh, beyond the reach of the common man.

If entropy is increasing, where is it coming from?
