The Hottest Natural and Artificial Temperature in the Universe

Leave a comment

The hottest temperature ever measured and/or observed was within the Large Hadron Collider located on the border of Switzerland and France. When lead particles are smashed together within this particle accelerator, for a split second the temperature reaches 4,000,000,000,000 (4 trillion) degrees Celsius which is hotter than a supernova explosion, albeit the theoretical maximum possible temperature of the universe is believed to be 20 orders of magnitude greater. Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has a value of 1.416785(71)×1032 kelvin. Temperatures above this are believed to be physically impossible because as particle energies become larger and larger, the gravitational forces between them inevitably become as strong as the other 3 fundamental forces which essentially boils and breaks down both the universe and space time. Outside of laboratory conditions however, the hottest naturally occurring place within the universe is the quasar 3C273 (the 273rd entry in the Third Cambridge Catalogue of Radio Sources), a blazing region surrounding a supermassive black hole approximately 2,400,000,000 (2.4 billion) light years away from the Earth, with matter within its accretion disk being measured at temperatures of approximately 10,000,000,000,000 (10 trillion) kelvin, making it far hotter than the core of any star, and 400,000x hotter than the core of the sun, rivaling the conditions of the universe right after the Big Bang

Tudor Period Mining and Metal Smelting

Leave a comment

During the Tudor period, lead was utilized to build roofs and windows because it was easily mailable and resistive to corrosion. Farmers would mine for lead during the summer months when their crops did not need tending to in order to generate additional income. Mining during the summer months could earn an extra £5.00 which equates to £25,000 as of 2012 when accounting for inflation. Entire families often worked within the mines because 50 barrels worth of ore and soil would be extracted per day to meet the quota of what was required to be profitable. Smelting involved the use of white coal which is effectively dried wood from a kiln and was always setup upon windy hilltops or mountains because the wind would cause the fire blaze with more intensity therefore reaching higher overall temperatures. The best wood to make white coal is oak. Kilns must be airtight, so gaps were filled with clay. Knowing a kiln to be airtight was easily verifiable by searching for smoke as if smoke only came out of only the front entrance, the kiln was considered airtight. Ore was smashed into small pieces to help it smelt more rapidly which yielded approximately an 80% return upon investment. Metals were then refined using a secondary kiln, and smelted to remove any ash or impurities. The first burn removes ore from the rock, and the second burn removes impurities with the main impurity being sulphur. Molds were constructed using sand and wood to create divots which allowed the ore to be molded into blocks much the same as a modern day bar of gold. The sand gives the mold an indentation which archeologists use to identify Medieval bars of smelted ore

Textile Pollution of the Citarum River in Indonesia

Leave a comment

The Citarum River (pronounced “chit-ah-rum”) in Indonesia is considered to be the most heavily polluted river in the world with over 400 textile factories situated nearby which choose to dump their industrial waste directly into the river itself, treating the river as a sewer system which carries away waste. The problem is so intense that the Indonesian military has been implemented to help clean up the area but corporations have resorted to dumping their waste products at night and because the unseen chemicals are the real threat to those living near the river, these companies are permitted to continue dumping as no one can definitively prove their culpability without scientific measurements which are difficult to ascertain as Indonesia is a developing country. Corporations have even begun to strategically place their waste pipes under water so that they can pollute with impunity as no one can physically see the pollution being dumped. Water darker than its surroundings, steam, bubbles, and froth are all key signs which activists use to spot these illegal port systems. It’s difficult to pin point which factories produce textiles for western companies as western companies virtually always refuse to disclose which factories they work with. Some of the largest corporations in fashion (e.g. H&M, the Gap, Levi’s etc.) have revealed their sources but even with this disclosure, some of these companies have been linked to factories within this region. Indonesia isn’t a top 5 global producer of textiles, so to say that Indonesia is part of an even larger problem, is an accurate statement. Most people who live near the Citaum River use the river for bathing, drinking, and/or cooking, and noticeable dermatological effects have been noticed by those living within the area. The primary problem with the Citarum River is with heavy metals (e.g. mercury, cadmium, lead, arsenic etc.). Long term exposure to these substances can cause neurological problems as brain function becomes permanently damaged. These heavy metals are so dire that they can actually lower the intelligence quotient of children who are developing and attending their education. 28,000,000 (28 million) people rely upon the Citarum River daily and eat foods (e.g. rice) irrigated with its waters. Human rights activists have engaged these corporations by physically blocking piping and ducts which have caused the affected corporations to start hiring mercenary criminals to follow and attack those known to be a part of this resistance. Western consumers are the primary cause and possible solution for this problem because if there are no clients willing to purchase the garments, the industry as a whole will shift, not because of political pressure or governmental oversight, but rather because of sales. The problem is not centralized in Indonesia as other developing countries (e.g. India, Bangladesh, China etc.) are equally negatively impacted
