Raising the energy point out of an atom’s nucleus employing a laser, or thrilling it, would allow the development of probably the most precise atomic clocks ever to exist and permit essentially the most precise measurements of time and gravity. Such an atomic clock could even rewrite many of the fundamental legislation of physics.

C++eleven launched a standardized memory model. What does it suggest? And how is it going to impact C++ programming?
