Find the part to make your special gal complete (or if your vehicle is a male, your special guy). Side Note: According to https://www.theglobeandmail.com,in March of last year, “Forty-nine per cent of drivers assign a gender to their vehicle. Of these, 88 per cent of women view their ride as “female” – compared with 55 per cent of men who do so as well. Over all, there are twice as many “female” cars (32 per cent) on the road as “male” (16 per cent). Back to the topic at hand, if you are interested in being a vendor, please contact the office as tables were still available at time of publication. This is a great opportunity to get out of the house with family or friends or even on your own to see some interesting items, find what you’ve been looking for, chat with some of our members, meet some new friends with the same interests and have a great breakfast or lunch in our fabulous 50s Diner!

Page 4 Through the Windshield Love, Leave a Light on- The history of light and the longest lasting light bulb The candle in the window during Christmas time can be traced back to the Irish around 1691- 1778 when the British Government created the Penal Laws. Irish Catholics would light a candle in the window and leave the door unlocked to allow the priest to sneak in to say mass. Over time, the light became a beacon of hope for any passerby during the season. The candle alerted strangers that there would be food and shelter welcome to them. When settlers immigrated to North America, they continued the tradition. As one blogger wrote: “As a beacon of light for ships guides them safely, so on land the light guides them to safety on land”. “During Colonial times, the candle in the window took on a few different meanings. Following the Irish tradition, it was a beacon of safety, letting visitors know that their home would offer them refuge.” During pioneer times, this was a practice that served as a guiding light for people as they traveled to visit their neighbors. The candle also represented a signal that a family member that was away, either at war or for other reason. The family lit the candle every night in hopes that their missing member would find their way home safely. “A candle in the window could also represent joyous news, like the birth of a baby”. A light in the window was also used to alert runaway slaves that it was a safe harbor to stop.

  • Incandescent: Light Bulbs and Conspiracies1
    Dr Grace Halden recently completed her PhD at Birkbeck, University of London. Her doctoral research on science fiction brings together her interest in philosophy, technology and literature. She has a range of diverse VOLUME 5 NUMBER 2 SPRING 2015 publications including an edited book Concerning Evil and articles on Derrida and Doctor Who. [email protected] Article Incandescent: 1 Light Bulbs and Conspiracies Grace Halden / __________________________________________ Light bulbs are with us every day, illuminating the darkness or supplementing natural light. Light bulbs are common objects with a long history; they seem innocuous and easily terminated with the flick of a switch. The light bulb is an important invention that, as Roger Fouquet notes, was transformational with regard to industry, economy and the revolutionary ability to ‘live and work in a well-illuminated environment’.2 Wiebe Bijker, in Of Bicycles, Bakelites and Bulbs (1997), explains that light bulbs show an integration between technology and society and how these interconnected advancements have led to a sociotechnical evolution.3 However, in certain texts the light bulb has been portrayed as insidious, controlling, and dehumanising. How this everyday object has been curiously demonised will be explored here. Through looking at popular cultural conceptions of light and popular conspiracy theory, I will examine how the incandescent bulb has been portrayed in dystopian ways.4 By using the representative texts of The Light Bulb Conspiracy (2010), The X-Files (1993-2002), and Thomas Pynchon’s Gravity’s Rainbow (1973), I will explore how this commonplace object has been used to symbolise the malevolence of individuals and groups, and the very essence of technological development itself.

  • Modeling and Characterization of Interfacial Stress Transfer in Mechanoluminescent
    Modeling and Characterization of Interfacial Stress Transfer in Mechanoluminescent Smart Particulate Polymer Composites Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Srivatsava Krishnan Graduate Program in Mechanical Engineering The Ohio State University 2020 Dissertation Committee Prof. Vishnu Baba Sundaresan, Advisor Prof. Ahmet Kahraman Prof. Ryan Harne Copyrighted by Srivatsava Krishnan 2020 ii Abstract This dissertation focuses on the development of mathematical models for stress distribution and transfer in smart particulate polymer composites and its application for structural prognosis and health monitoring. Contemporary mathematical models for polymer composites, especially particulate composites, are mainly focused on predicting macroscopic behavior and fall short of estimating of stress transferred to particulate phase. The mechanical interactions between particulate and matrix phases are extremely significant for the composite if the particulate phase exhibits smart functional behavior. To address this knowledge gap, interfacial mechanics is modeled by a cohesive zone model (CZM) and its parameters are estimated through direct experimental methods. This mathematical framework is applied to predict stress transferred to particles and model modulus relaxation in elastomeric mechanoluminescent composites. Consistent experimental evidences presented in this dissertation suggest that light emission from elastomeric mechanoluminescent composites may correlate with the structural health of the composite. It is hypothesized that health degradation in particulate composites occurs through damage accruing at the interface between the particles and the matrix. It is also hypothesized that interfacial damage leads to reduced stress transfer to the particulate which in the case of EML particles results in reduction of emission intensity.

  • Planned Obsolescence: Exploring the Issue
    Briefing May 2016 Planned obsolescence: Exploring the issue SUMMARY Although no overarching definition of planned obsolescence exists, the term 'planned obsolescence' (of products or technology) is described as the intentional production of goods and services with short economic lives, stimulating consumers to repeat purchases too frequently. The incandescent light bulb with an engineered shorter lifespan (the Phoebus cartel case) is one example from the past of proven planned obsolescence. Data suggest that the median lifespans of certain categories of product have been shortening, and consumer organisations have drawn attention to more recent suspected cases of planned obsolescence in connection with washing machines, inkjet cartridges, electronic devices, etc. One Member State – France – recently introduced a definition of planned obsolescence into its legislation, making it a punishable offence. No specific EU rules mention planned obsolescence, but the subject ties in with EU legislation on ecodesign, waste, use of natural resources, consumer information and the new package from the European Commission on the circular economy. The main consumer concerns and problematic strategies associated with the issue are: design features that do not allow repair, upgradability or interoperability with other devices; the unavailability of spare parts and high repair costs; and marketing strategies pushing consumers to buy new, fashionable products and replace existing ones very quickly. Various ways to curb the practice of planned obsolescence

    The Mystery of the Centennial Bulb: an Incandescent Light Bulb© by Martin Kykta at [email protected] MAK Electro-Optics 2021 We owe a lot to the incandescent light bulb. The incandescent light bulb (ILB) has provided for increased industry and a better society. They replaced dangerous and sooty gas lamps. ILBs lit our factories, offices, schools, hospitals and roads. The discovery led to the development of modern electronic devices. The hot filament was known to emit electrons (Edison effect) which could be collected and controlled. This led to the development of vacuum tubes, radio, television and early electronic computers. Today ILBs are headed toward obsolescence and replacements by LED lamps because ILBs have a low efficacy and are short lived (1,000 hours). Is that really always true? How do we explain the 60 watt Shelby bulb (called the Centennial Bulb) still in continuous operation since 1901 at the fire house in Livermore California? In 2015, it was still operational after one million hours. You can visit the website that shows this bulb still in operation, Livermore's Centennial Light Bulb (centennialbulb.org) [1]. The ILB is simple right? We should be able to understand why the centennial bulb is still around. The ILB is a wire that is made hot by a current flowing through it. For inspiration, watch A YouTube video on recent MIT graduates, who were asked if they could light a bulb with a 1.5 volt battery and a wire, https://www.youtube.com/watch?v=8ve23i5K334 ) [2]. Most graduates said yes. One person wraps the wire around the metal base of the bulb and touches the bottom of the battery with the end of the wire and the base of the bulb to the top of the battery.

All the fifty years of conscious brooding have brought me no closer to the answer to the question, “what are light quanta?” Of course today every rascal thinks he knows the answer, but he is deluding (fooling) himself. - Albert Einstein, 1951 Early days, a light beam was thought to consist of particles. Later, the phenomena of interference and diffraction were demonstrated which could be explained only by assuming a wave model of light. Much later, it was shown that phenomena such as photoelectric effect and Compton effect could be explained on if we assume a particle model of light. * Ajoy Ghatak, Optics, Macgraw Hill, 2010 * The photoelectric effect is the observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner can be called photoelectrons. The phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry (Wikipedia). * *Compton scattering is the inelastic scattering of a photon by a charged particle, usually an electron.
