Introduction to general relativity this energy loss would be too small to be detectable, but this energy loss was observed in 1974 in a binary pulsar called PSR1913+16. In such a system, one of the orbiting stars is a pulsar. This has two consequences: a pulsar is an extremely dense object known as a neutron star, for which gravitational wave emission is much stronger than for ordinary stars. Also, a pulsar emits a narrow beam of electromagnetic radiation from its magnetic poles. As the pulsar rotates, its beam sweeps over the Earth, where it is seen as a regular series of radio pulses, just
Racing the Beam speed electron beam across the screen. "Racing the Beam" discusses the history of the VCS platform and the design decisions that impacted the types of games that could be written for it. Specific titles such as "Combat", "Pitfall!" and "Yars' Revenge" are analyzed from a technical and cultural perspective. "Racing the Beam" is the first in a series of books on early video game platforms, and has been cited by modern Atari 2600 enthusiasts as an inspiration for attempting to write new games for the platform.
