The Reason Icebergs Sink Ships

1 Comment

The reason that an iceberg is able to cut into the side hull of a ship (e.g. Titanic etc.) or any other marine vessel is dual fold. The first reason is because steel becomes more brittle, the colder it gets. Steel created during the early 20th century was not tempered as steel is during the modern day. The second reason is because of inertia, weight, and force. An iceberg can slash through steel the same way a tree can rip through a vehicle that has hit it. An iceberg is a large, immovable object, so whether the hull is comprised of wood or titanium, the ice will always win out as it has more inertia and mass. To provide a frame of reference, bone is incredibly strong and tensile, however if a brick which is harmless while at rest, slams down from a height above the arm, the force it imparts is enough to break said bone

American Theoretical Physicist Robert Oppenheimer’s Reaction to the First Successful Nuclear Weapon Detonation

2 Comments

After the Trinity nuclear launch test which occurred on July 16, 1945, the first nuclear detonation in human history, when Manhattan Project lead Julius Robert Oppenheimer was asked about the reaction of himself and others on that fateful day Oppenheimer responded, “we knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture the Bhagavad Gita. Vishnu is trying to persuade the prince that he should do his duty and to impress him takes on his multiarmed form and says, Now, I am become Death, the destroyer of worlds. I suppose we all thought that one way or another” (this phrasing/sentence structure while confusing in English, is the correct direct translation from Sanskrit)

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

The Renewable Resource of Urine Powered Electronics

1 Comment

Urine is rich in minerals and it is believed that this resource will be able to be harnessed and extracted efficiently and cost effectively at some point in the future to produce electrical energy. At the Bristol Robotics Laboratory in the U.K., urine is being studied as a potential energy resource for residential use within the near future (e.g. used to charge a smartphone etc.). Charging a smartphone with urine requires battery like fuel cells with Professor Ioannis Leropoulos (pronounced “yan-iss lee-raw-po-lis”) having developed a system capable of meeting this requirement. The application itself is referred to as “microbial fuel cell” technology, a system which leverages live bacteria to generate electrical current. Urine contains carbon, phosphorus, potassium, sulphur, magnesium, and creatinine, all elements which microbes require to continue living and growing which is why this technology functions as it does. The microbial fuel cell’s central tube is porous ceramic, allowing urine to permeate the tube and microbes to colonize it. As the elements of urine are consumed, electrons generated by the microbes are picked up by the cells of opposing wire coils, creating a battery. Not just any microbe will suffice however, as specific microbes are required for this process to be effective. To source the correct microbes, scientists leverage a plethora of microbes available within the natural environment (e.g. lake, pond, river sediment etc.). Each fuel cell produces 1.5 volts of electrical current, and when linked together in series, output can be increased to a level which is useful for daily activities. The system is able to be scaled so that it can be built into future homes, allowing for individuals and families to recycle urine as a means of generating electrical energy. Leropoulos’ work has been funded by the Bill & Melinda Gates Foundation as well as by the European Commission among others and is close to becoming commercially available as of 2020. For this system to benefit users, separate urinals would be installed but with redirected plumbing to funnel urine away from becoming mixed with common sewage and into a collection container, providing an on demand resource which can be utilized when needed

The Japanese Shinto Faith

1 Comment

The Japanese Shinto religion translates to mean “way of the gods” in Japanese and primarily focuses upon ancestors and nature, with practitioners believing that every aspect of the universe has a deity (e.g. rivers have a god, mountains have a god, soil has a god etc.) with ancestors believed to have created the world for the current generation living within it. Japanese architecture is an excellent example of Shintoism as Shinto shrines are left in a minimalist state of color and simplicity, unlike contemporary Chinese architecture which is highly colorful and decorative. Shinto shrines never depict imagery of deities as the wood of the architecture itself is representative of nature, and from that simplicity and minimalism. This is also because it is believed that so many gods exist within nature that it would be foolish to only highlight a few in particular. Practitioners of Shinto observe festivals and holidays but no particular day of prayer, unlike monotheistic religions (e.g. Sunday for Christianity, Friday for Islam and Judaism etc.). There is no mainstay scripture of morality or ethical system attached to Shintoism. In Shintoism, old shrines are dismantled and moved for new shrines to be erected every 20 years. The 3 main elements of Shintoism are the mirror, precious stones, and wood

Civilizations Mastery of Metal By Manipulating Fire

Leave a comment

The more carbon rich a fuel is, the more heat it produces. Typical wood fires burn at 700 degrees Celsius, however 6000 years ago, ancient people discovered the adaptation of burning wood in a low oxygen environment, only partially burning, but in doing so creating a much purer carbon rich fuel; charcoal. Charcoal can burn at temperatures upwards of 1100 degrees Celsius, hot enough to melt ore out of rock. The mastering of metal produced tools, finance, and weaponry, forever changing the evolutionary story of human beings. By the Middle Ages, the production of charcoal for metal smelting and metal work was a major industry

 

The Discovery of the Route Which Allowed Explorers to First Climb Mount Everest

Leave a comment

British born George Mallory, the person tasked with heading the team who first set out to climb Mount Everest in 1921, overlooked what is now used as the doorway to Mount Everest, the entry point of East Rongbuk Glacier. When Mallory first viewed this entry point, a narrow cliff within the mountainside wall, he dismissed it as too modest and small to warrant further investigation. Canadian Oliver Wheeler however was educated in the science of topography and geography from his father who surveyed the Canadian west coast Rocky Mountains and because of this, he did not view the dimensions of the cut to be as important as the pulse of water pouring out of that cut every afternoon. This enormous volume of expelled water signaled to Wheeler that a glacier had to be present at the head of the valley as it was the only possible explanation which fit. On July 30, 1921, Wheeler set out for the East Rongbuk Glacier and as he anticipated, he was able to make it up the ice field within 6 short days. As the East Rongbuk Glacier widened and curved around, it came directly to the base of the North Col, a sharp edged pass carved by glaciers in the ridge connecting Mount Everest and Changtse (pronounced “chang-see”). This opening became the key to unlocking Mount Everest and is still leveraged by climbers into the modern day. 6 days after setting out, on August 4, 1921, Wheeler sent a dak runner, which is essentially a Tibetan messenger, with a sketched map indicating his discovered exploit of the armor of Mount Everest for Mallory

The Person Who Invented the Internet

Tim Berners-Lee created the internet. Berners-Lee is the son of mathematicians, his mother and father part of a team who programmed the worlds first commercial stored program computer, the Manchester University Mark 1. Berners-Lee developed the original concept for the internet as a young boy, after discussing how machines might one day possess artificial intelligence with his father who was reading a book upon the human brain. Berners-Lee realized that if information could be linked, knowledge which would not normally be associated together, it would become much more useful. Ted Nelson helped expand upon Berners-Lee’s invention by developing the concept of hypertext, a method of digitally linking from one section to another. The development of the internet during the 1960’s became user friendly during the 1990’s as it became increasingly available to the public. Berners-Lee was able to take something which was too complicated for most people to use, and create a system which made it user friendly. Incompatibility between computers had been a thorn in the side of technology for years as specialized cables were needed to ensure computers could communicate with one another. Berners-Lee had the brilliant idea to create a centralized block which all cables would feed into so that one central unit could be used for every computer in the world to communicate. Berners-Lee furthered this idea by designing the concept of anything being linked to anything. A single global information space would be birthed as a direct result of this, a system with common rules, which would be accessible to everyone, that effectively provided as close as possible to no rules at all; a decentralized system. This arrangement would allow a new person to use the internet without having to ask anyone else. Anyone, anywhere, could now build a server and put anything upon it. Berners-Lee decided to name his creation the “World Wide Web” because he thought of it as a global network. Berners-Lee took his intellectual property and provided it to the public free of charge, despite having many commercial offers. Berners-Lee felt that the idea would not become the largest and greatest invention of humanity had it not been free, democratized, and decentralized. The fact that anybody could access the internet and anybody could put content onto it, made the internet massively popular early on and grew at a rate of 10x year upon year. Berners-Lee also created the World Wide Web Consortion, an institution which was designed to help the World Wide Web to develop and grow

The Person Who Invented Ecommerce

Leave a comment

Michael Aldrich was an English inventor, innovator and entrepreneur who in 1979, invented the concept of ecommerce, enabling online transaction processing between consumers and businesses. Aldrich achieved this feat by connecting a modified television set to a transaction processing computer which could process purchases in real time via dedicated telephone line. This system entitled “Videotex” had a simple menu driven, human to computer interface, which predated the internet by more than a decade. In 1980, Aldrich invented the Teleputer, a multipurpose home information and entertainment centre which was a combination of the personal computer, television, and telecom networking technologies. Aldrich created the Teleputer using a modified 14” color television which was connected to a plinth containing a Zilog Z80 microprocessor running a modified version of the CP/M operating system and a chip set containing a modem, character generator and auto-dialler. The Teleputer operated as a stand alone, color, personal computer during an era when computer screens were primarily monochromatic. The Teleputer contained software and networking capabilities using dial up or leased telephone lines. The Teleputer system itself included 2 floppy discs, each with 360 kilobytes of memory, later upgraded to a 20 megabyte harddrive, a keyboard, and a printer

The Reason Aritifical Intelligence Differs From Traditional Software

Leave a comment

Recently, many of the improvements made within the artificial intelligence sector have been due to the technology of “deep learning” which is also referred to as an “artificial neural network”. Traditional software is not intuitive as it simply follows a set of instructions predetermined by a programmer. If the software runs into a new problem which it has no answer prewritten for, it crashes. Deep learning is different as software can now write its own instructions instead of reading the instruction(s) of a programmer. Currently, as of 2021, deep learning is the equivalent of an all powerful, dim witted genie as it has the ability to evaluate the pixels of a photograph of a bottle of water, and can recognize with astonishing accuracy photographs of other water bottles, however it has no idea what the concept of water or the water bottle itself is, what the end user does to drink from the water bottle, what the end user needs the water for etc. This differs in human beings however as humans learn from a sample size of one, and are able to surmise the purpose of water and everything else which is relevant from witnessing it being used upon a single occasion
