The scientific discoveries and technological innovations produced by Bell Labs research and engineering were critical not only to the evolution of global telecommunications but, more widely, they had a considerable impact on the technological base of the global economy and, indeed, on our daily lives.
Bell Labs is the source of many significant contributions, of course, in the area of telephony, but also in memory devices, imaging devices, system organization, computers and software technology, as well as acoustics, optics, switching, transmission, wireless and data communication. New principles, new materials, new devices, and new systems from Bell Telephone Laboratories resulted in new industries, hundreds of new products, and thousands of new jobs. The invention of the transistor in 1947, and subsequent advances in related solid-state device and circuit technology formed the basis of a multibillion dollar global industry and ultimately enabled the digital world. Shannon’s seminal paper titled “A Mathematical Theory of Communication,” published over 60 years ago, gave birth to Information Theory and has stood as the guiding foundation for communications scientists and engineers in their quest for faster, more efficient, and more robust communications systems ever since. The charge-coupled device (CCD), a technology that transforms patterns of light into useful digital information, is the basis for many forms of modern digital imaging. It has launched entirely new industries and markets and is widely used in devices as diverse as digital cameras, video cameras, and bar code readers as well as in security monitoring, medical endoscopy, modern astronomy and video conferencing. Optical technology and systems, from earliest advances in lasers to low-loss fiber, opto-electronic waveguide devices, and high capacity WDM transmission systems have enabled worldwide connectivity to build a truly global community. Cellular telephone service, the concept that multiple lower-power transmitters could be spread throughout a region employing automatic call handoff and frequency reuse changed the face of communications. Multiple input multiple output (MIMO) smart antenna technology in concert with LTE, based on OFDM technology, will define next generation wireless, delivering wider coverage and higher throughput.
“Technological innovation” is more than just invention. It is a process, often long and costly, of transforming new scientific knowledge into feasible technology, introducing it to use, and making its benefits available to the public. “Technical integration” is intended to emphasize the more subtle flow of an intangible—engineering information and understanding. Not only has Bell Labs innovated, but it also showed the world technical integration of the innovations.
With this posting of the Bell System Technical Journal from volume 1 issue 1 in July 1922 to the final issue published in December 1983, we are pleased to be able to open the vault of this knowledge to our global technical colleagues.
Alcatel-Lucent is now proud to partner with IEEE to provide access to the Bell Labs Technical Journal (1996-present) and all of its predecessors: the Bell Labs System Technical Journal (1922-1983), AT&T Bell Labs Technical Journal (1984), and AT&T Technical Journal (1985-1996).
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
