In recent times the facility and precision of lasers have revolutionized the field of atomic physics. Within the a person hand, lasers have drastically greater the precision with which the attribute wavelengths of atoms can be measured.
The best way to have an understanding of the difference is applying the next example. Suppose You can find an atomic string residence known as "identify", and if you connect with [self setName:@"A"] from thread A, phone [self setName:@"B"] from thread B, and contact [self identify] from thread C, then all operations on unique threads will likely be executed serially which suggests if one thread is executing a setter or getter, then other threads will wait around.
