PHYSICS‚TECHNOLOGY AND SOCIETY. Technology and society or technology and culture refers to cyclical co-dependence‚ co-influence‚ co-production of technology and society upon the other (technology upon culture‚ and vice-versa). This synergistic relationship occurred from the dawn of humankind‚ with the invention of simple tools and continues into modern technologies such as the printing press and computers. The academic discipline studying the impacts of science‚ technology‚ and society and vice versa

Radium Girls was a chemical disaster that happened during the 1920’s. Women in watch making were being exposed to Radium all the time. These women worked painting wristwatches‚ and in order to get a fine point on their paintbrush they licked the brush‚ therefore swallowing the paint. Some of them also painted their teeth and nails with this paint since they were told that it wasn’t harmful. The paint had Radium in it‚ therefore exposing them to Radium. They painted the numbers on the watches. They

Radioactive material can be found in some products such as microwave ovens‚ x-ray machines‚ and radon gas. The most dangerous sources of radioactive material are nuclear weapons‚ and nuclear power plants if a critical failure takes places. Radioactive pollutants can have very harmful to the human body and the in environment‚ but they are fairly easy to contain if the proper measures are taken. Radioactive pollution can be defined as the emission of high-energy particles or radioactive substances

Hazardous materials can be silent killers‚ almost every household or workplace contains various harmful substances therefore it is important to have the basic knowledge of these contaminants‚ where to find them‚ and what to do if exposed. Asbestos is a natural occurring mineral that is used in a number of different materials. Asbestos is not a concern if left undisturbed; however renovation‚ reconstruction or demolition can disturb these materials and release asbestos fibers into the air. Asbestos

It was the cold seemingly endless winter of 1947 in Paris ‚ Latin Quarter. . Sheets of snow put the rest of the district in almost complete obscurity; all but steeples and tall spires were invisible‚ on such a bleak day as this. The railway station was a vast cavity made to look smaller by the hoards of hagglers‚ travellers‚ tourists‚ natives and locals. Beggar boys being whisked from sight and hidden by wardens with preying eyes and superstition written all over them.The wonderful smell of the patisserie

Detrital-zircon geochronology is an up and coming method to provide information on sedimentary rock provenance. Zircon is used for this method because of its resilience against chemical and physical weathering; in other words zircon is an indicator that is ubiquitous within sedimentary rocks. Zircon also tends to concentrate uranium and thorium (to a lesser extent) and excludes lead. Two parallel uranium-lead decay routes exist‚ 238U to 206Pb with a half-life of 4.47 billion years and 235U to 207Pb

As I read this article‚ about the history and beauty of Machu Picchu‚ a historical monument located in Cusco Region‚ Urubamba Province‚ Machu Picchu District in Peru‚ I wondered how much effort it would have taken to build it. We know as a fact that the Incas did not have any type of advanced technology to help them carry this heavy rocks. It also surprised me the organization they had. Each “area” was directed for one purpose for instance: farming‚ building‚ hunting‚ etc. On paragraph 11‚ they

Miss Emily ’s House: A Symbol of Neglect Miss Emily ’s House: A Symbol of Neglect "A Rose for Emily‚" is the remarkable story of Emily Grierson‚ whose death and funeral drew the attention of the town. The bizarre outcome is further emphasized throughout by the symbolism of the decaying house‚ which parallels Miss Emily ’s physical deterioration and demonstrates her ultimate mental disintegration. Emily ’s life‚ like the house which decays around her‚ suffers from lack of

well as by other means. In the last twenty years‚ for example‚ the use of isotopes (as “tracer” elements) has become a valuable tool for the study of reaction kinetics (in slow reactions). 3. CONCENTRATION DEPENDENCE OF REACTION RATES Normally experimental data of kinetic investigations are records of concentrations of reactants and/or products as a function of time for constant temperatures (taken at various temperatures). Theoretical expressions for reaction rates (involving concentration changes)
