The use of tools by early humans was partly a process of discovery and of evolution. Early humans evolved from a species of foraging hominids which were already bipedal, with a brain mass approximately one third of modern humans. Tool use remained relatively unchanged for most of early human history. Approximately 50,000 years ago, the use of tools and a complex set of behaviors emerged, believed by many archaeologists to be connected to the emergence of fully modern language. It has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result. Scientists and engineers usually prefer to define technology as applied science, rather than as the things that people make and use. More recently, scholars have borrowed from European philosoph...

Jeff Wayne achieved a long-lasting success with his 1978 electronic rock musical version of The War of the Worlds. In 1961 Josef Tal established the Centre for Electronic Music in Israel at The Hebrew University, and in 1962 Hugh Le Caine arrived in Jerusalem to install his Creative Tape Recorder in the centre. In the 1990s Tal conducted, together with Dr. Shlomo Markel, in cooperation with the Technion – Israel Institute of Technology, and VolkswagenStiftung a research project aimed at the development of a novel musical notation system for electronic music. Improvements to the technology were made using the AC biasing technique, which significantly improved recording fidelity. Although these developments were initially confined to Germany, recorders and tapes were brought to the United States following the end of World War II. These were the basis for the first commercially produced tape recorder in 1948. For articles published under an open access Creative Common CC BY license, an...
