The Reason the World Clock Starts in Greenwich, England

1 Comment

The reason the world clock starts in Greenwich, England is because during the 19th century, the majority of sea charts used Greenwich, England as the Prime Meridian for the 0° coordinate. In addition to this, during the early advent of the British railway network, trains could end up in accidents if the timing of coming into and/or out of stations was off by even a small margin of error. Because the sun rises earlier in some parts of Britain and later in the rest, these variables needed to be compensated for which was accomplished by introducing more accurate clocks and the concept of time zones. Up until this point, horsepower was the fastest way to travel and because of that, sundials which had been invented in and used since the 9th century A.D., were satisfactory. It was only with the emergence of locomotives that this system of time keeping became antiquated

The First Use of Spaces In Writing

Leave a comment

 

Ancient Greek writing did not observe spaces as modern day written language does so all words were connected, forming a continuous string of text. Aerated text with irregular spaced intervals did not develop until the late 7th century A.D. and standard modern day spacing after each term did not develop until the 11th century A.D. Ancient Greek writing also observed the practice of Boustrophedon (pronounced “boos-trah-fee-don”) which is when text is written and read right to left instead of left to right as modern day English and most other, however not all other, world languages do (e.g. Japanese, Arabic, Hebrew etc.)

Inventions Mesopotamia Gifted to the World Still Used During the Modern Day

The Mesopotamians invented large scale wheat production, the potters wheel which allows for the making of pottery bowls, cups, and plates, used for consumption and collection, boats which could sail all the way to India created from reeds, and the stylus which is effectively a pen created from reeds, which led to the development of the world’s first writing system. These are just a few examples gifted to the world by the first great civilization; Mesopotamia. Every written word in the western world can trace its origins back to the cuneiform of Mesopotamia and the study of mathematics also derives directly from the Mesopotamian civilization. Reeds were used for measuring distances, based upon the size of the Pharaoh Djer (pronounced “jur”), with the first standard measurement derived from Djer’s elbow crease to the tip of his middle finger, and the second standard measuring a full arm span of both arms spread as wide as the body will allow them. The Mesopotamians invented the mathematics of time keeping by using the creases of their fingers with each finger containing 3 creases therefore 12 creases for each hand. This system included the thumb and when accounting for the back of the hand, a base system was invented which was used to count between 0 – 60. This system was primarily used to tell time, as there are 60 seconds in a minute and 60 minutes in an hour, which meant that the day would be divided into 2 periods each of 12 hours

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

The Ancient Lighthouse of Alexandria, Egypt

Leave a comment

The Lighthouse of Alexandria was one of the original 7 Wonders of the Ancient World. Standing more than 350’ tall, the Lighthouse of Alexandria and was clearly observable to passing ships sailing up to 50 kilometers away. Originally built in 280 B.C., after guiding ships into the port and city of Alexandria for 15 centuries, the Lighthouse of Alexandria collapsed in 1323 due to a series of earthquakes which leveled the structure and caused it to tumble into the Mediterranean Sea. The Citadel of Qaitbay (pronounced “kate-bay”), a 500 year old fortress, now sits at the site of the once standing lighthouse with many of the stones within this structure, pieces of the original Lighthouse of Alexandria, installed after being dredged up from the ocean floor. Although the Lighthouse of Alexandria was originally designed to safely bring ships into the port of Alexandria, the Citadel of Qaitbay acted in opposition as a repellent centuries later, designed to keep enemies (e.g. Ottoman Turks) out of Egypt. No ship was permitted the privilege of docking in the Alexandria harbor without forfeiting all books on board for a short period of time until they could be translated and/or copied outright by scribes

The Discovery of the Sunken S.S. Titanic

Leave a comment

The S.S. Titanic’s shipwreck site was found by the U.S. Navy whilst embarking upon a clandestine military submarine sea voyage operation in 1982. The intent of the mission was to surpass the Russians on every front, including land, sea, air, and space. Geologist and Navy Captain Robert Ballard was the person who developed the mission idea by suggesting that the U.S. Navy scour the seafloor to gather intelligence and search for evidence of Soviet placed hardware. The original intention of the mission was to locate and recover 2 U.S. Navy submarines which were classified as top secret nuclear attack vessels and lost during the 1960’s. The first submarine was the U.S.S. Scorpion, lost in 1968 with 99 onboard, and the second was the U.S.S. Thresher, lost in 1963 with 129 onboard. Recovery of these vessels during the 1960’s was limited to the Sound Navigation and Ranging technology of the era, commonly abbreviated as “SONAR”. Ballard only had 12 days to locate the S.S. Titanic during the mission without exposing his cover story, a feat which was unable to be completed by the French and the Americans, despite having much longer time spans and multiple expeditions to achieve this goal. Ballard narrowed down the search area to 80 square kilometers and focused towards the south as he believed that ocean currents would have carried sunken debris in that direction. Ballard continued searching for a trail of scattered debris from the S.S. Titanic and on the 9th day of the expedition, with time quickly running out, the operators of the remotely operated vehicle ARGO, found wreckage from a modern iron ship which appeared to be from the early 20th century. It was confirmed shortly after on September 1, 1985 at 12:48 AM that these remains were 1 of the 29 boilers belonging to the S.S. Titanic. It had been 73 years since the S.S. Titanic was last seen, resting nearly 4 kilometers below sea level, with it’s 1500 onboard passengers and crew

The Future Technology of Carbon Nanotubes

2 Comments

The atomic structure of carbon, more specifically naturally occurring diamond, is neatly stacked in a cuboid shape. Carbon nanotubes use carbon but instead stack their atoms in a hexagonal shape. The result is a material which weighs virtually nothing, yet is stronger than any material known upon Earth, including poly-paraphenylene terephthalamide, more commonly referred to as “Kevlar”, zylon, and titanium. Some scientists have argued that carbon nanotubes will most likely be the strongest substance in the known universe and that nothing will ever have the ability to surpass its strength. Carbon nanotubes have a strength of 200 gigapascals; to provide frame of reference, the strongest materials known to civilization have a strength of approximately 5 gigapascals. 1 gigapascal, which is commonly abbreviated as “GPa”, is equal to 1,000,000,000 (1 billion) pascals, and 1 pascal, which is commonly abbreviated as “Pa”, is the SI unit for pressure defined as “1 newton per 1 square meter”. If a space elevator ribbon made of carbon nanotubes stretching 100 kilometers were ever to break (e.g. the counterweight above breaking), it would gently float down to Earth because it would only weighs 7 kilograms per every 1 kilometre of length

The First Industrial Revolution, Second Industrial Revolution, and Impending Third Industrial Revolution

Leave a comment

Industrial revolutions require 3 key components to occur, 3 defining technologies which emerge and converge to create the catalyst needed to usher in a new era of human achievement and progress. The first component is new methods of communication technologies to make communication more efficient and to manage economic and social life (e.g. video conferencing), the second is new sources of energy to more efficiently power economic and social life as well as governance (e.g. renewable energy technologies), and the third is new modes of mobility and logistics to more efficiently move economic and social life as well as governance (e.g. on demand ride sharing). The First Industrial Revolution was caused by the discovery of a new source of energy; coal. Coal powered the new communications medium, the steam powered press, and a new logistics structure via the locomotive railway. When these 3 technologies converged, much of the world (e.g. the whole of Europe) changed seemingly overnight. As a direct consequence of the First Industrial Revolution, business models moved toward market capitalism and major city hubs began developing ushering in the modern world format. The Second Industrial Revolution occurred in the U.S. during the late 19th and early 20th century with the advent of the telephone in the late 19th century, and the advent of radio and television in the early and mid 20th century. At approximately the same time that the telephone and telecommunications networks were being developed, the U.S found a new source of energy which was oil in Texas, United States of America. Henry Ford compounded this discovery by producing a cost effective combustion engine, powered by oil which provided new logistics and mobility technology. The Second Industrial Revolution however is now fading away due to the impact it has had upon the Earth’s climate and humanity is now upon the precipice of a Third Industrial Revolution. The internet has become the new communication medium, millions of people are now adopting renewable energy (e.g. solar, wind, geothermal etc.) and it is predicted that when autonomous vehicles connect to smart roads, the last piece of this puzzle will be complete, thrusting humanity into its 3rd epic epoch

The Projected Impact of Trees Upon Climate Change

1 Comment

Throughout history, it is estimated that human beings have cut down 2,000,000,000,000 (2 trillion) – 2,500,000,000,000 (2.5 trillion) trees. This means that even if human beings plant 1,000,000,000,000 (1 trillion) trees within the coming decade(s), this would only replace 40% – 50% of what has been taken from nature. Drones are now being used to plant trees, capable of planting 120 trees per minute per drone at 10% of the traditional cost to do so. If humanity were to plant 20,000,000,000 (20 billion) trees per year for 50 years, which is a sustainable rate, this still only equates to 1,000,000,000,000 (1 trillion) trees which once again would only replace 40% – 50% of that which has been taken. It would take 9000 drones operating 200 days per year to accomplish this feat. Drone production for this project would not require drones more complicated than a modern day smartphone. Trees, plants, grasses etc. are essentially crystallized air, and are more than 95% formed by air. This means that the mass of a tree is equitable to the mass of oxygen which it has been crystallized from, effectively adhering to the Law of the Conservation of Mass, the First Law of thermodynamics. The average tree weighs 2 tonnes with 50% of this weight being carbon, which means that 1,000,000,000,000 (1 trillion) trees is directly equitable to 1,000,000,000,000 (1 trillion) tonnes of carbon. The land requirement to produce such an ambitious project would take half the land mass of Brazil, with larger trees actually requiring less land, paradoxically

Sweden’s Major Contributions to Vehicular Safety Standards Worldwide

In 1959, Nils Bohlin (pronounced “neels bow-leen”) created the 3 point seatbelt while working for Volvo, an invention which Volvo intentionally designed to be patent free so that the advent could be utilized and implemented globally in a concerted effort to save lives everywhere. This was one of the first examples of open source technology in business and manufacturing. It’s been estimated that the seatbelt has saved more than 1,000,000 (1 million) lives over the past 40 years as of 2020. Swedish company Autoliv (pronounced “ow-tow-leeve”) furthered this pursuit towards safety by creating the seatbelt pre-tensioner which instantaneously reels in seatbelt slack during a vehicular accident and has also helped to design newer, better airbag systems and advanced artificial intelligence automobile visual systems
