What Made Bell Labs Special? Ley in Recent Years, the High Pay and Excellent Working Conditions at Bell Labs Attracted Many Who Might Look Elsewhere Today
physicsworld.com Christmas books Andrew Gelman What made Bell Labs special? ley in recent years, the high pay and excellent working conditions at Bell Labs attracted many who might look elsewhere today. Second, there was nothing to do at the labs all day but work. I have known lots of middle-aged profes- sors who don’t spend much time teaching but don’t do any research either. At Bell Labs it was harder to be deadwood. Located as it was in the middle of nowhere, the Murray Hill campus was not a place to relax, and if you were going into the lab every weekday anyhow, you might as well work – there was nothing better to do. Several researchers, including Shannon and Shockley, had sharp mid-career productivity declines – but after they left Murray Hill.

Edison and the Lumière brothers worked assiduously to find a way to preserve and reproduce sound and images. The numerous inventions conceived in this period such as the Kinetophone, the Vitascope and the Cinematograph are testament to this and are nowadays consid- ered the forerunners of cinema. Most of these new technologies were presented at public screenings which generated a high level of interest. They attracted people from all social classes, who packed out the halls, theatres and hotels where they were held. This paper presents a review of the newspa- per and magazine articles published in Spain at the turn of the century in order to study the social reception of the first film equip- ment in the country, as well as to understand the role of music in relation to the images at these events and how the first film systems dealt with sound.

G.W.A.T.T. (Global 'What If' Analyzer of Network Energy Consumption)
G.W.A.T.T. New Bell Labs application able to measure the impact of technologies like SDN & NFV on network energy consumption WHITE PAPER Increased energy consumption is a key challenge for the Information and Communications Technologies (ICT) industry. Network energy bills represent more than 10 percent of operators’ operational expenses. With the advent of the Internet of Things era, and the inexorable consumption of video and cloud services promising to drive massively increased traffic across networks, it is even more important for operators to have a complete view of the energy impact of different technology and architectural evolution options. G.W.A.T.T. (Global “What if” Analyzer of NeTwork Energy ConsumpTion) has been built to allow operators and industry stakeholders to better understand these challenges. This application visualizes the current and future communication networks and forecasts key trends in energy consumption, energy efficiency, cost and carbon emissions based on a wide variety of traffic growth scenarios and technology evolution choices. It is intended as a mind-sharing tool to grasp the importance of the energy challenge and how innovation and new technologies can help address these issues in the future. EXECUTIVE SUMMARY The explosion of the Internet traffic volume resulting from both the worldwide broadband subscriber base extension and the increasing number and diversity of available applications and services require a relentless deployment of new technologies and infrastructures to deliver the expected user-experience. At the same time, it also raises the issue of the energy consumption and energy cost of the Internet and more generally of the Information and Communication Technologies (ICT). -

Measurement of the Cosmic Microwave Background Radiation at 19 Ghz
Measurement of the Cosmic Microwave Background Radiation at 19 GHz 1 Introduction Measurements of the Cosmic Microwave Background (CMB) radiation dominate modern experimental cosmology: there is no greater source of information about the early universe, and no other single discovery has had a greater impact on the theories of the formation of the cosmos. Observation of the CMB confirmed the Big Bang model of the origin of our universe and gave us a look into the distant past, long before the formation of the very first stars and galaxies. In this lab, we seek to recreate this founding pillar of modern physics. The experiment consists of a temperature measurement of the CMB, which is actually “light” left over from the Big Bang. A radiometer is used to measure the intensity of the sky signal at 19 GHz from the roof of the physics building. A specially designed horn antenna allows you to observe microwave noise from isolated patches of sky, without interference from the relatively hot (and high noise) ground. The radiometer amplifies the power from the horn by a factor of a billion. You will calibrate the radiometer to reduce systematic effects: a cryogenically cooled reference load is periodically measured to catch changes in the gain of the amplifier circuit over time. 2 Overview 2.1 History The first observation of the CMB occurred at the Crawford Hill NJ location of Bell Labs in 1965. Arno Penzias and Robert Wilson, intending to do research in radio astronomy at 21 cm wavelength using a special horn antenna designed for satellite communications, noticed a background noise signal in all of their radiometric measurements. -
CHAPTER 3. Film Sound Preservation: Early Sound Systems
CHAPTER 3. Film Sound Preservation: Early Sound Systems 3.1 Film Sound Preservation In the introduction I argued that the nature of film sound consists of different dimensions: the textual and material dimensions, the human and technological dimensions, the institutional, experiential and memorial dimensions. Each of these should be taken into account in preservation and presentation practices. Some of these dimensions were investigated in the first two chapters, where I outlined a set of key concepts related to recorded sound that I derived from social and artistic sound practices as well as media theories: the noise of the material carriers and technological devices, cleaned and cracked sounds, the notion of soundscape and high fidelity, and the concepts of media memory and audiovisual trace. In the following chapters I will further analyze the nature of film sound and its core dimensions beginning with the analysis of film sound preservation and presentation case studies. In this chapter, I examine preservation and restoration projects of films where the issue of sound is particularly relevant, while chapter four analyzes the work of film heritage institutions with respect to film sound presentation. The case studies discussed here are prompted by the following questions: how can we preserve and restore film sound materials? What are the different approaches to film sound preservation and restoration? What are the problems and defects of different film sound carriers and apparatuses? Which kind of actions can be taken to solve those problems? How can the actions undertaken to preserve film sound be recorded and documented? How is it possible to exhibit and display film sound in present-day theatres? The answers to these questions as provided by the case studies will contribute to the definition of the nature of film sound, which will be elaborated in chapter five. -
I : the Discovery of the Cosmic Microwave Background
Class 19 : The cosmic microwave background and the “Hot Big Bang” theory Discovery of the cosmic microwave background Basic idea of the Hot Big Bang I : The discovery of the cosmic microwave background Penzias & Wilson (Bell-Labs) 1 Arno Penzias & Robert Wilson (1964) Were attempting to study radio emissions from our Galaxy using sensitive antenna built at Bell-Labs Needed to characterize and eliminate all sources of noise They never could get rid of a certain noise source… noise had a characteristic temperature of about 3 K. They figured out that the noise was coming from the sky, and was approximately the same in all directions… The COBE mission Built by NASA-Goddard Space Flight Center Launched Nov. 1989 Purpose was to survey infra-red and microwave emission across the whole sky. Primary purpose – to characterize the CMB. Had a number of instruments on it: FIRAS (Far infra-red absolute spectrophotometer) DMR (Differential Microwave Radiometer) DIRBE (Diffuse Infrared background Experiment) 2 Our Galaxy observed by the DIRBE instrument on COBE 3 Almost uniform intensity of microwaves in all directions (isotropic 2.7K black body radiation) 4 Subtracting off the mean level leaves with a “dipole” pattern… what is this?? Subtracting off the dipole finally reveals the emission from the Galaxy that Penzias and Wilson were looking for! 5 Subtracting contribution from Galaxy reveals fluctuations in the CMB WMAP (2004) 6 II : The hot big bang model Penzias & Wilson had discovered radiation left over from the early universe… The hot big bang model… Independently developed by James Peebles and George Gamov They suggested that the universe started off in an extremely hot state. -

Recent observations showed that only 4 degrees Kelvin above absolute zero using liquid galaxy clusters – the visible parts of our universe – were nitrogen – the equivalent of cooling your freezer down to flying away from each other. In other words, the fabric of -269 ºC.

Bell Laboratories Record Tomer Wishes
THE PICTURE OF THE FUTURE The Bell System is about to add PICTURE- PHONE® service to the many services it now of- fers customers. A major trial of a Picturephone system is presently under way, and commercial service is scheduled for mid 1970. Because Pic- turephone service is a large undertaking that will have a profound effect on communications, the RECORD is pleased to be able to present this special issue describing the new system for our readers. Special issues have become an important part of the RECORD's continuing story of science and technology at Bell Labs. The first one, in June 1958, dealt with the transistor and marked the tenth anniversary of its invention at Bell Labs. Since then there have been special issues on the TELSTAR® project, No. 1 Ess, and integrated elec- tronics. In addition, there have been single-topic issues devoted to the N-3 and L-4 carrier trans- mission systems. We hope to continue to present such special issues from time to time as a way of highlighting subjects of special importance.

LEVIN 4.014 The gramophone record, the musical idea, the written notes, the sound waves, all stand in the same internal representational relationship to one another that obtains between language and the world. —Ludwig Wittgenstein, Tractatus logico-philosophicus (1921) “All-of-a-tremble”: The Birth of Robotic Speech On February 16, 1931, the New York Times ran a story on a curious development that had just taken place in England: “Synthetic Speech Demonstrated in London: Engineer Creates Voice which Never Existed” read the headline.1 The day before, so the article began, “a robot voice spoke for the first time in a darkened room in London . uttering words which had never passed human lips.” According to the accounts of this event in numerous European papers, a young British physi- cist named E.A. Humphries was working as a sound engineer for the British International Film Co. when the studio ran into a serious problem. A synchro- nized sound film (then still quite a novelty) starring Constance Bennett had just been completed in which the name of a rather unsavory criminal character hap- pened to be the same as that of a certain aristocratic British family. This noble clan was either unable or unwilling to countenance the irreducible—even if seemingly paradoxical—polysemy of the proper name (so powerful, perhaps, was the new experience of hearing it actually uttered in the cinema) and threat- ened a libel suit if “their” name was not excised.
