Global and China Laser Equipment and Processing Industry Report, 2013-2017|
|Price: $ 2400 |
The European and American economic crisis, Asian economic slowdown and a number of other factors have impacted the development of global laser industry, and reduced the growth rate of global industrial laser sector to single digit. The growth rate of global laser system market declined from 16% in 2011 to 6% in 2012, and is expected to further drop to around 4% in 2013.
As a global processing and manufacturing center, China has continuously expanded the installation of laser processing equipment and occupied more than 10% of the global market. However, due to the weak downstream demand, the growth rate of Chinese laser equipment market in 2012 and 2013 both fell to below 10%. Among major enterprises, only Han’s Laser Technology and Shenzhen Sunshine Laser and Electronics Technology have achieved business growth, other ent

Physicist suggests speed of light might be slower than thought|

Physicist James Franson of the University of Maryland has captured the attention of the physics community by posting an article to the peer-reviewed New Journal of Physics in which he claims to have found evidence that suggests the speed of light as described by the theory of general relativity, is actually slower than has been thought.
The theory of general relativity suggests that light travels at a constant speed of 299,792,458 meters per second in a vacuum. It's the c in Einstein's famous equation after all, and virtually everything measured in the cosmos is based on it in short, it's pretty important. But, what if it's wrong?
Franson's arguments are based on observations made of the supernova SN 1987A it exploded in February 1987. Measurements here on Earth picked up the arrival of both photons and neutrinos from the blast but there was a problem the arrival of the photons was later than expected, by 4.7 hours. Scientists at the time attributed it to a likelihood that the photons were actually from another source. But what if that wasn't what it was, Franson wonders, what if light slows down as it travels due to a property of photons known as vacuum polarization where a photon splits into a positron and an electron, for a very short time before recombining back into a photon. That should create a gravitational differential, he notes, between the pair of particles, which, he theorizes, would have a tiny energy impact when they recombine enough to cause a slight bit of a slowdown during travel. If such splitting and rejoining occurred many times with many photons on a journey of 168,000 light years, the distance between us and SN 1987A, it could easily add up to the 4.7 hour delay, he suggests.
If Franson's ideas turn out to be correct, virtually every measurement taken and used as a basis for cosmological theory, will be wrong. Light from the sun for example, would take longer to reach us than thought, and light coming from much more distant objects, such as from the Messier 81 galaxy, a distance of 12 million light years, would arrive noticeably later than has been calculated about two weeks later. The implications are staggering distances for celestial bodies would have to be recalculated and theories that were created to describe what has been observed would be thrown out. In some cases, astrophysicists would have to start all over from scratch.Abstract
The effects of physical interactions are usually incorporated into the quantum theory by including the corresponding terms in the Hamiltonian. Here we consider the effects of including the gravitational potential energy of massive particles in the Hamiltonian of quantum electrodynamics. This results in a predicted correction to the speed of light that is proportional to the fine structure constant. The correction to the speed of light obtained in this way depends on the gravitational potential and not the gravitational field, which is not gauge invariant and presumably nonphysical. Nevertheless, the predicted results are in reasonable agreement with experimental observations from Supernova 1987a.

Great Invention Of Science- Solar Energy Products|
As the world is getting modernized day by day and huge number of electrical goods are coming to our way. Even more energy consumption is going to be expected. There is a way by which you can make minimize the use of electricity at homes, that way is the maximization in the use of solar products. The use of solar energy can be the best replacement for electricity.
Many people think going solar can be a little costly, yet it is not at all expensive. And aside from spending an amount of money, the use of these products are worthy to spend your money with because it can give you lots of benefits.
Now-a-day Solar Energy in India
is getting a common thing. Though, the solar products which are available these days helps you a lot in saving your consumption of electricity. Now, there are many solar products available in the market such as solar rechargeable later and acts as a best replacement of the light bulb. This solar later can give you light from 7to 12 hours without spending electricity.
Another great invention in the field of solar is solar module. This device will help you a lot so that you can use the solar energy in your home, particularly in your appliances. It has a specific number of voltages and as well as a power supply that will back up all the appliances in your homes which needs the aid of electricity.
