James Conca reviews the uranium enrichment deal made with Iran.

It is no wonder that Iran wants this deal as badly as it seems. It is a way out of a very tricky and dangerous situation. Countries having the bomb never seem to get attacked, but those that give up their nuclear programs completely tend to end badly. Just ask Iraq and Libya. To avoid this fate, Iran has to back away from nuclear weapons while retaining a nuclear energy program.

The U.S. understands that this deal is a good step toward that end. A final deal will include a structure that precludes the ability to make a weapon, such as abandoning or altering the reactor at Arak, and closing the Fordow enrichment facility because it is basically immune from attack being under a mountain. But the whole deal doesn’t have to be done all at once.

All things considered, this deal with Iran is a good one for the world.

Robert Hayes at Newsok reviews time travel physics

Travel backwards in time is mathematically consistent with all known physical phenomenon but not in the way you probably expect, there are some caveats. The existence of antimatter has been empirically known for almost 100 years now. The antiparticle for an electron can either be called an anti-electron or a positron. A normal electron has a negative charge and an anti-electron has a positive charge. Similarly a proton has a positive charge but an anti-proton has a negative charge. Whenever a normal particle comes into contact with its antiparticle, they annihilate each other and are converted into pure energy in the form of gamma ray photons. All anti-matter particles are effectively equivalent to their normal matter counterparts with the exception that anti-matter can be considered to have negative energy. The difference in energy when an anti-matter particle encounters its matter counterpart is simply total energy of the gamma rays released when they annihilate each other.

Nextbigfuture – Hongyanhe 2 has been connected to the Chinese electricity grid, the 18th reactor in the country to do so.

The unit is a CPR-1000 pressurized water reactor, on which construction was started in 2008. The first unit at the site has been operating on a commercial basis since June and now unit 2 is set to follow in a matter of months

Nextbigfuture – Pakistan Prime Minister Nawaz Sharif announced Tuesday that his country will build six more civil nuclear power plants. According to the prime minister, Pakistan would produce 40,000 MW of power from nuclear plants till 2050 and the government’s priority was to start work on power projects to overcome the energy shortage.
