Giant Cows Eat Venus; Earth Next

Giant Cows Eat Venus; Earth Next On the evening of June 6, 2012, a satellite with its camera pointed toward the sun sent the first 500 GB of its daily report back to base. Clouds covered the world thousands of miles below, where two summer interns were supposed to be observing the centurys last transit of Venus through its eyes. Their display showed an uninterrupted sphere of flames. One squinted at the screen. “Shouldn’t we see it already? When was it supposed to start?” “Half an hour ago,” said the other. They stared at the screen for another minute. “Good grief,” said the first, “and I wanted to run for president someday. What’ll happen to us if all our calculations were wrong, and there isn’t a transit today at all?” The second scowled at him. “Our calculations aren’t wrong,” he said. “The transit of Venus is a fairly predictable thing.” He paused, switching the settings on the screen. “Listen,” he said, “I dont know whats going on, but we’ll upload the footage from 2004. We’ll reconstruct it from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. It’ll look different. No one will notice.” The first shifted his weight in his seat and smiled uncomfortably. “You really don’t think anyone will notice?” he said. “Of course not,” said the second. And almost no one did. Most of the world was overcast, but somewhere in the Pacific Ocean a cruise ship floated under one of the few patches of clear sky. A couple leaned over the railing on the deck, squinting at the setting sun through cardboard eclipse glasses. “Is that it?” “No, honey, that’s a bug. It should be on the top right.” “I don’t see it. All I see is the sun. Do you see it?” “No, honey, I don’t see it.” “Is that it?” “No, honey, that’s another bug.” And so on, until the red, uneclipsed sun disappeared over the horizon. A month later, almost all of Boston descended on the Longfellow and Harvard bridges and, in boats and on the bank, the stretch of the Charles River that connected them. A warm, thick breeze reflected off the clouds and the water. The crowd gathered in the growing darkness, interrupted by the lights of Boston and the red lightning in the distance. The Longfellow bridge was evacuated. A patrol boat crisscrossed from one bank to the other, warning kayakers to stay out of the coming storm: Please find shelter,” he said. “The thunderstorm contains“â€"he pausedâ€" “lightning. The fireworks started, finally, to cheers from the crowd and a rumbling that didn’t quite sound like thunder or fireworks. Minutes later the storm started as well, pummeling the river through the fireworks. The crowd bent away from the wind and water blowing off the river. The rain pummeled their backs while they squinted at the booming fireworks behind them. Finally the rain stopped. The lights on both sides of the river vanished, block by block, until the river and the crowd were lit only by the fireworks. The ground rumbled again, louder this time. A few minutes later the last firework folded into the water, leaving the Charles River and the crowd in silence and darkness. Now unmistakable, a deep, munching sound echoed against the buildings on either side of the river. Almost all of that is actually true, except for the mysterious power outage and the mysterious munching and the mysterious disappearance of Venus. Summer has so far been a mix of foreboding clouds and heat. The photos below are from the Boston side of the river before a thunderstorm. Most of campus is to the left of the frame; you can see the Green Building on the left edge. The photos above are from the Cambridge side of the river before the fireworks, also before a thunderstorm. (Click for larger versions.) Ominous weather is my favorite kind of weather.   =) My UROP is actually as exciting and mysterious as I tried to make the rest of this blog post. And it’s real! I’m working on a low cost, high-risk project in the same lab I’ve been in for the past year. It’s extremely unlikely to succeed, but it’ll be darn awesome if it does. Every day is completely uncharted territory, with rapids at every turn. At the moment things seem to be going very well, but I might change my mind by the end of the day. Since it’s far behind me, I’m now going to share a big secret about my past year at MIT: it hasn’t all been fun. The past two semesters have been tough, academically and otherwise. When I was applying to MIT, I coped with the potential for low grades and low self-esteem by telling myself that I wanted MIT to take me apart and make me better. The past year has without a doubt been a taking apart, culminating in ripping apart and eating bags of black tea at my final exams. For about a month after finals I kept having weird nightmares where our transcripts were tattooed into our backs at the end of every term and I didnt want to go out in a swimsuit. Now is hopefully the rebuilding. Here are some things Ive learned: I’ve learned that some experiences are worth having, even if (especially if?) you know they’ll hurt. Stories aren’t interesting if nothing bad happens. I’ve learned that big, exciting things happen in small, not always exciting steps. I’ve learned that money has the power to dissolve friendships. Ive learned that you can’t get everyone to like you. There is absolutely no point in not being yourself if that’s what it takes to try. There are a select few who will love you even when you spend a week pretending to be a tomato. Hold on to those. I’ve learned that stupidity and evil can be hard to distinguish, especially at the thick intersection of software and money. I’ve learned that success is transient and haphazard and does not emulate its keepers. Hard work doesn’t always pay off. The good guys dont always win. Ive learned that the things worth trying are those you wont regret experiencing if they dont work. I’ve reevaluated what I look for in friends and in myself. It took me an embarrassingly long time to realize that in all situations, kind and good are more important to me than intelligent or likely to succeed. Ive learned that friends and family are much, much more important to me than grades or money. I’ve learned that my own awareness of my aptitude can be more limiting than my actual abilities. Just as excessive self-confidence can limit your worldview and put incompetent people in important positions, too little can choke the abilities that you decided you don’t have. Its a tricky balance. Perhaps most importantly, I’ve learned that the people we think are unattainably great never had to earn a special license to fill that role. There is no threshold of age or coolness after which you are suddenly authorized to do big things. This epiphany is especially relevant to those of you who are in high school. Want something? Go get it. You don’t need an MIT education to start doing amazing, world-changing things, especially if you take advantage of the Internet. Did you know that lightning makes raindrops bigger? This summer I’m also lightly studying for next semester and mentally preparing for the next two years. I’m going to have to kick it up a few notches, and I’ll have to grapple for those notches as I go. Like I said, ominous weather is my favorite kind of weather. Bring it on, Dark and Mysterious Future.

The Historical Use of the Mercury Mineral, Cinnabar

Cinnabar, or mercury sulphide (HgS), ​is a highly toxic, naturally occurring form of the mercury mineral, which was used in the ancient past for producing a bright orange (vermillion) pigment on ceramics, murals, tattoos, and in religious ceremonies. Cinnabars Earliest Use The primary prehistoric use of the mineral was grinding it to create vermillion, and its earliest known use for this purpose is at the Neolithic site of Çatalhà ¶yà ¼k in Turkey (7000-8000 BC), where wall paintings included cinnabars vermillion. Recent investigations in the Iberian peninsula at the Casa Montero flint mine, and burials at La Pijotilla and Montelirio suggest the use of cinnabar as a pigment beginning approximately 5300 BC. Lead isotope analysis identified the provenance of these cinnabar pigments as coming from the Almaden district deposits. In China, the earliest known use of cinnabar is the Yangshao culture (~4000-3500 BC). At several sites, cinnabar covered the walls and floors in buildings used for ritual ceremonies. Cinnabar was among a range of minerals used to paint Yangshao ceramics, and, at Taosi village, cinnabar was sprinkled into elite burials. Vinca Culture (Serbia) The Neolithic Vinca culture (4800-3500 BC), located in the Balkans and including the Serbian sites of Plocnik, Belo Brdo, and Bubanj, among others, were early users of cinnabar, likely mined from the Suplja Stena mine on Mount Avala, 20 kilometers (12.5 miles) from Vinca. Cinnabar occurs in this mine in quartz veins; Neolithic quarrying activities are attested here by the presence of stone tools and ceramic vessels near ancient mine shafts. Micro-XRF studies reported in 2012 (Gajic-KvaÃ… ¡cev et al.) revealed that paint on ceramic vessels and figurines from the Plocnik site contained a mixture of minerals, including high purity cinnabar. A red powder filling a ceramic vessel discovered at Plocnik in 1927 was also found to include a high percentage of cinnabar, likely but not definitively mined from Suplja Stena. Huacavelica (Peru) Huancavelica is the name of the largest mercury source in the Americas, located on the eastern slope of the Cordillera Occidental mountains of central Peru. Mercury deposits here are the result of Cenozoic magma intrusions into sedimentary rock. Vermillion was used to paint ceramics, figurines, and murals and to decorate elite status burials in Peru in a range of cultures including Chavà ­n culture (400-200 BC), Moche, Sican, and the Inca empire. At least two segments of the Inca Road lead to Huacavelica. Scholars (Cooke et al.) report that mercury accumulations in nearby lake sediments began rising about 1400 BC, probably the result of the dust from cinnabar mining. The main historic and prehistoric mine at Huancavelica is the Santa Barbà ¡ra mine, nicknamed the mina de la muerte (mine of death), and it was both the single largest supplier of mercury to the colonial silver mines  and the major source of pollution in the Andes even today. Known to have been exploited by the Andean empires, large-scale mercury mining began here during the colonial period after the introduction of mercury amalgamation associated with the extraction of silver from low-grade ores. Amalgamation of poor quality silver ores using cinnabar was begun in Mexico by Bartolomà © de Medina in 1554. This process involved smelting the ore in grass-fired, clay-lined retorts until vaporization yielded gaseous mercury. Some of the gas was trapped in a crude condenser, and cooled, yielding liquid mercury. Polluting emissions from this process included both the dust from the original mining  and the gasses released into the atmosphere during smelting. Theophrastus and Cinnabar Classical Greek and Roman mentions of cinnabar include that of Theophrastus of Eresus (371-286 BC), a student of the Greek philosopher Aristotle. Theophrastus wrote the earliest surviving scientific book on minerals, De Lapidibus, in which he described an extraction method to get quicksilver from cinnabar. Later references to the quicksilver process appear in Vitruvius (1st century BC) and Pliny the Elder (1st century AD). Roman Cinnabar Cinnabar was the most expensive pigment used by the Romans for extensive wall paintings on public and private buildings (~100 BC-300 AD). A recent study on cinnabar samples taken from several villas in Italy and Spain were identified using lead isotope concentrations, and compared with source material in Slovenia (the Idria mine), Tuscany (Monte Amiata, Grosseto), Spain (Almaden) and as a control, from China. In some cases, such as at  Pompeii, the cinnabar seems to have come from a specific local source, but in others, the cinnabar used in the murals was blended from several different regions. Poisonous Medications One use of cinnabar not attested in archaeological evidence to date, but which may have been the case prehistorically is as traditional medication or ritual ingestion. Cinnabar has been used for at least 2,000 years as part of Chinese and Indian  Ayurvedic  medicines. Although it may have some beneficial effect on some illnesses, human ingestion of mercury is now known to produce toxic damage to kidney, brain, liver, the reproductive systems, and other organs. Cinnabar is still used in at least 46 traditional Chinese patent medicines today, making up between 11-13% of Zhu-Sha-An-Shen-Wan, a popular over-the-counter traditional medicine for insomnia, anxiety, and depression. That is about 110,000 times higher than allowable cinnabar dose levels according to the European Drug and Food Standards: in a study on rats, Shi et al. found that ingestion of this level of cinnabar does create physical damage.

Knowledge About Ionising Radiation Among Dentists Free Essays

Introduction: Dental radiography has evolved over the last decade. The evolution began with the introduction of new changes to the operations of dental radiology. Some examples of these changes include new machines, smaller beam sizes, increased filtration, advanced techniques, faster film speeds and large increases in utilization (White, 1992, 118-26). We will write a custom essay sample on Knowledge About Ionising Radiation Among Dentists or any similar topic only for you Order Now However, concerns do remain about the possible adverse effects of dental radiography on humans for several reasons: firstly, these procedures remain the only common type of diagnostic radiography capable of being performed without intensifying screens, requiring concomitantly higher doses. Secondly, the targets to film distance are short. The third reason is the emitted rays are in near to sensitive organs in the head and neck region. These examinations are among the most common diagnostic radiographic procedures performed today. Based on these examinations, previous studies have concluded an increased risk for salivary gland, thyroid, and brain tumors (UN Scientific Committee on the Effects of Atomic Radiation, 2000, Vol.1). Literature Review According to UNSCEAR 2000 Report (European Union, 1997, 22), dental radiography is one of the most frequent types of radiological procedures. Although the exposure associated with dental radiography is relatively low, any radiological procedure should be justi?ed and optimized in order to keep the radiation risk as low as reasonably achievable (Radiation Protection 136). Dose assessment is recommended to be performed on a regular basis to ensure that patient exposure is always kept within the recommended levels and to identify possible equipment malfunction or inadequate technique (Alme’n, Mattsson, 1996, 81-89). With comparison to adults, children have been found to be more radiosensitive (International Commission on Radiological Protection, 1991, Publication 60). Therefore, increased attention is recommended in supervising children to minimize the medical radiation exposure to children. All radiological procedures carried out on children must adapt to special radiation prote ction measures, which aims at recognizing and implementing possible dose reduction strategies in order to eliminate unnecessary and therefore un-justi?ed radiation exposure.It is the responsibility of the health care professional to provide firsthand knowledge to the patients undergoing all radiological procedures and processes. The dentist can answer queries of any patient with regard to radiation hazards, which can be reliable provided their knowledge is adequate and up-to-date. The knowledge related to radiation is taught during undergraduate training in medical colleges. However, dentists grossly underestimated the proper risk regarding proper use of medical imaging tools and their associated radiation risks (International Commission on Radiological Protetion, 1991, Publication 60). On the other hand, the incorrect information about its safety and effectiveness, is made and promoted by some dentists who are paid and sponsored by the manufacturers of these devices to lecture a nd give seminars promoting their products. The conflict of interest does add extra concern about the safety of these products. OBJECTIVES METHODS The objectives of the study will be to: Assesses dentist’s knowledge about ionizing radiations and their hazard on the patient. Identify the level of understanding regarding use of ionizing equipment’s among dentist. METHODS: The research will assess the ionizing radiations knowledge, risk and awareness among dentists in Australia and Jordan. The approach to this assessment will use a survey that will be distributed to 300 dentists. These are some of the questions that I will be asking the dentists: 1-Name (optional) 2- Sex 3- Age 4- Dental school 5- Year graduated 6- Residency 7- Experience 8- Risks associated with ionizing radiation on human tissue 9- Methods of mitigating or preventing ionization radiation during practice 10- Best practices associated with ionizing radiation HYPOTHESIS The null hypothesis or my expected outcome of the survey results is that of the better hospitals, or the institution of allied health care that provide ionization radiation during practice to have dentists that understand the risks better than other doctors. The other doctors are understood to be in practice in less stellar institutions of allied healthcare. The alternative hypothesis is that doctors at the stellar institutions as well as doctors at the lesser institutions are unaware of the risks associated with ionizing radiation.

What Is Love Essay Thesis Example For Students

What Is Love? Essay Thesis Presented to: Mrs. ConnellPresented by: Cory HawkeDate: March 26, 1998What is this thing called love? This simple question begs for an answer. The symptoms oflove are familiar enough. A drifting mooniness in ones behavior and thought, the fact that itseems as though the whole universe has rolled itself up into the person of the beloved, somethingso wonderful that no one on earth has ever felt about a fellow creature before. Love is ecstasyand torment, freedom and slavery. Love makes the world go round. Until recently, scientists wanted nothing to do with it. The reason being that love is lifesmost intense feeling and love is mushy. Science is hard. Anger and fear are emotions that havebeen researched in labs and can be quantified through measurements. Pulse and breathing rates,muscle contractions, etc. Love cannot be charted or measured. Anger and fear have a definiteroll in human survival: fighting or running. Love does not. And since it is possible for humans tomate and reproduce without love, all the swooning and sighing is beside the point. We will write a custom essay on What Is Love? Thesis specifically for you for only $16.38 $13.9/page Order now Up until the past decade, serious scientists assumed that love was all in the head. Now theresearch has become more intense. This may be because of the spreading of AIDS and that casualsex carries mortal risks. Others point to the growing number of female scientists and suggest thatthey may be more willing then their male colleagues to take love seriously. Whatever the reason,science has come around to a view that romance is real. That it is bred into our biology. We have always been influenced by love in our culture. It is a dominant theme in music,television, films, novels and magazines. It is a commercial bliss. People will do or buy anythingwith a promise of romance. Does this imply that love is just a false emotion that we picked up after years of it beingdrilled into our head again and again by society? If romance was purely a figment, unsupportedby any rational or sensible evidence, then surely most would be immune to it by now. But thathas not happened. Love is still in the air. In 1992 a study was conducted by anthropologists William Jankowiak and EdwardFischer. They found evidence of romantic love in at least 147 or the 166 cultures studied. Thisdiscovery should be enough to wipe out the idea that love is an invention of the mind rather than abiological fact. Among the things that anthropologists tended to do in the past was ask questions aboutthe courtship and marriage rituals. This turned out to be the wrong way of going about thin gs. Inmany cultures, love and marriage do not go together. Weddings can have all the romance ofcorporate mergers, signed and sealed for the family or territorial interests. More and more scientists are coming to believe that love is truly a biologicalpredisposition. That we are all scientifically fated to love by our genes and chemicals. A lot ofpeople would just as soon to not want to know. No one knows exactly how to place this mysterious emotion. It comes in many shapesand forms and different people and cultures celebrate it in different ways. But perhaps it is betterthat we dont know the scientifics and just enjoy it. Why pull at such a beautiful and wonderfulthing and try to pick it apart when to the beholder it is already virtually perfect? The more we try

A Farewell to Arms1 essays

A Farewell to Arms1 essays The book A Farewell to Arms, written by Ernest Hemingway is about the love story of a nurse and a war ridden soldier. The story starts as Frederick Henry is serving in the Italian Army. He meets his future love in the hospital that he gets put in for various reasons. I thought that A Farewell to Arms was a good book because of the symbolism, the plot, and the constant moving of the main The symbolism in A Farewell to Arms is very much apparent. To the main character in novels, nights have always been a sign of death, or something negative to happen. Another one of the symbolisms in A Farewell to Arms is when Henry tries to escape from the Italian army by jumping off one of the ships the army was traveling on and running away from the army. This water symbolized new, clean life that he was going to live from now on. At this time, Henry goes off and finds his wife to be. The plot in A Farewell to Arms was always active. They were never staying in one place too long. It had a very good story line, which was a love story that ended up in a tragedy.
