Mobile phone
In addition to the standard voice function of a telephone, current mobile phones may support many other services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile phones attached to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).

Physics in Natural science
The study of the principles of the universe has a long history and largely derives from shortest observation and experimentation. The formulation of theories about the governing laws of the universe has been essential to the study of physics from very early on, with philosophy gradually yielding to systematic, quantitative experimental testing and observation as the source of verification. Key historical developments in physics include Isaac Newton's theory of universal gravitation and classical mechanics, an understanding of electricity and it's relation to magnetism, Einstein's theories of special and common relativity, the improvement of thermodynamics, and the quantum mechanical model of atomic and subatomic physics.
The field of physics is extremely broad, and can contain such diverse studies as quantum mechanics and theoretical physics to applied physics and optics. Modern physics is becoming increasingly specialized, where researchers tend to focus on a exacting area rather than being "universalists" like Albert Einstein and Lev Landau, who worked in multiple areas.
