The Parasol and the Advent and Evolution of the Umbrella

1 Comment

Parasols, the precursor to the umbrella, were initially comprised of tree leaves, specifically eucalyptus and palm branches. The original intent of the parasol was to stop ultraviolet radiation from the sun, from penetrating the skin and causing it to become tan. The term “parasol” is derived from the French term “para” which means “to shield from”, from the root Latin term “parare” (pronounced “pah-rah-ray”), and the French term “sol”, which means “sun”. Parasols and umbrellas can be separated by their appearance as parasols are typically colorful and lively whilst umbrellas are generally solid, muted colors (e.g. black, grey, white etc.). It was not until the 1750’s when English philanthropist Jonas Hanway began carrying an umbrella in public with the intent to avoid rain that the idea caught on as a social trend and a new technology. Umbrellas up until the 19th century were heavy, weighing approximately 10 lbs. as they were comprised of whale bone with wooden rods setup to support the canvas. In the 1920’s, Hans Haupt helped usher the next generation of umbrellas in by inventing the foldable umbrella, the same kind of umbrella used during the modern day

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 Advent of Oil Paint Storage Changing Artwork and the First Artist to Begin Painting Outdoors

Leave a comment

Tubed oil paint became available in 1841, superseding the traditional methods of storing paint in pigs bladders and glass syringes, which made traveling to a location and/or painting outside, suddenly possible, so that aspects of light and shadow would not have to be manufactured as with classical paintings, but rather they could be painted exactly as the artist laid witness to them. Claude Monet was the first Impressionist artist to start painting outdoors during the mid 19th century, often painting in the public’s view, outdoor scenery like The Manneporte which he painted in 1885

The Etymology of American Industrialist Henry Ford’s Model T Automobile and the First Mass Produced Vehicle

1 Comment

Henry Ford named the iconic Model T automobile as he did because of the way he built his company. Ford started with the Model A and continued to improve the design, moving through each letter of the alphabet the way modern software changes numerically with each upgrade (eg. Model A, Model B, Model C alongside software 1.0, software 2.0, software 3.0 etc.). It was Ford’s 20th design that met his stringent personal requirements allowing the Model T to become the first mass produced vehicle in 1908

The Craft of Venetian Mask Manufacturing for the Italian Festival of Carnival

2 Comments

Masks have been part of Venetian culture since at least the 12th century A.D. as it was in 1162 that the first Carnival festival occured, a city wide celebration which marks the period prior to Lent. Up until 500 years ago, classic Venetian masks were constructed of papier-mâché, a medium that some Venetian mask artists still utilize during the modern day. Strips of papier-mâché are laid into a mold made of resin and layer by layer they are covered in glue. All materials are designed to be non-toxic. When a mask is complete, artisans use scalpel blades to cut out the eyes and any rough pieces remaining (e.g. edges etc.). Once a mask dries, it is decorated with beautiful colors and artwork (e.g. floral arrangements etc.). This is often performed freehand with a pencil. Masks are then painted using beautifully ornate colors (e.g. blue, red, yellow etc.) and finished by adding accoutrements (e.g. 24 karat gold leaf etc.). The craft was almost lost when Napoleon Bonaparte conquered Venice, Italy in 1797 and banned Carnival and Carnival masks as he believed the event could spark rebellion. Benito Mussolini banned the celebrations once again in the 1930’s. Until the late 1970’s, Carnival was a largely forgotten relic but it has since observed a resurgence within popular culture

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

The First Personal Computer and its Ramifications Upon Technology

The Altair 8800 from Micro Instrumentation Telemetry Systems is considered to be the first personal computer, although ironically, the system itself did nothing as software had yet to be invented. Steve Jobs and Steve Wozniak used the Altair 8800 as the basis for the Apple I, the first ever Apple product. Additionally, Bill Gates and his team wrote Basic for the Altair 8800 and created Microsoft from that programming language

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 Person Who Invented the Internet

Leave a comment

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
