How Wedding Ceremonies Worked Within Europe During the Medieval Period

1 Comment

Medieval weddings were carried out much the same as they are during the modern day with any witnesses present being provided 3 distinct opportunities to object to the marriage with the most common objections being that the parties involved were too close in relation by blood and/or the age of the bride was too young to accept the concept of marriage and/or bare a child. A ring and a piece of gold or silver was placed upon the Christian Bible held by the priest conducting the ceremony, in an effort to have the ring blessed, after which the priest would take the brides right hand and in Latin say “In nomine Patris, et Filii, et Spiritus Sancti. Amen” which means “in the name of the Father, the Son, and the Holy Ghost. With truth” in Latin. The priest would touch each finger, starting with the thumb, after saying each part of the Holy Trinity, ending upon the 4th finger when saying “amen”, which became the finger which the wedding ring was placed upon. It was not uncommon for both men and women to wear their wedding rings on their thumbs or middle fingers until the 17th century as any finger was considered acceptable. After undertaking vows, both the husband and wife would lay down to be covered in a shroud, afterwhich they would arise as a newly married couple. This practice was symbolic of a marriage transforming 2 unique individuals into a single person married to Jesus Christ. Finally, the priest would then kiss both the bride and groom upon their face, typically the cheek, and put the couple to bed to ensure consummation of the marriage, at which point, the marriage ceremony was considered complete

How Armor Was Decorated During the Medieval Period

1 Comment

Armor was embroidered during the Medieval period by using oil and lead paint to mark off ornate areas which would stand out and perhaps be decorated with gold or other precious metals in a process referred to as “gilding”. Gold does not easily bind to any type of metal and the only way to properly do so is to undergo a process which involves mixing the gold with mercury. Once applied, a mixture of salt, vinegar, and copper sulphate, which is root killer, makes a paste which eats through the metal leaving the painted parts untouched, and resulting in an etched piece of armor. Blacksmiths sometimes heat treated armor which turned it a blueish hue which essentially rusts the metal as it is referred to as an “oxide” and an oxide occurs when a metal comes into contact with oxygen which reacts with the metal and creates a deposit when heated to a very specific temperature, as the heat is what shifts the red color of rust to the blue area of the color spectrum

The Condition of the Earth After the Chicxulub Asteroid Collision Which Caused the Extinction of Dinosaurs

Leave a comment

Immediately after the Chicxulub Asteroid collided with the Earth, heat from the fireball produced reached temperatures of 5500 degrees Celsius and produced a shockwave which broke the speed of sound, causing gale force winds equivalent to a hurricane. Everything within 965 kilometers was instantly decimated. Within 11 minutes of impact, the sky began to darken as debris which had been pushed up into the atmosphere started to settle back down. As these small spheres the size of a grain of sand descended back down to Earth, they heated up upon re-entry, identical to that of an asteroid, which provided the illusion of billions of simultaneous shooting stars. The energy produced during this re-entry barrage of heat was more intense than the sun for a brief period of time and made the sky glow red, as if it was comprised of liquid magma. This debris reflected heat back towards the Earth and effectively caused the Earth to act as an enormous radiator. To add to this damage, wildfires began sprouting up due to the intense temperature which caused heat and smoke to fill the atmosphere, compounding the damage already done. Strong winds helped perpetuate these fires and because so much of the Earth was affected, it only took a few hours to become globalized, engulfing the entire Earth in a mass fire which burned hotter than a regular fire due to the inability to dissipate heat sideways. In addition to this, gypsum which contains sulphur, blocked the sun and cooled the Earth over the long term. Gypsum had a seismic effect upon the world’s oceanic ecosystems as ocean acidification occurred due to sulphuric rain being produced by the gypsum within the atmosphere. The reflecting of the sun caused 75% of all plants to die as the Earth only received as much light during mid day as what is present during a cloudy, moonless night of the modern day

The Insect Used to Produce Ink Throughout History

Leave a comment

The andricus kollari wasp in particular has played a significant role throughout human history as it is one of the main ingredients of ink. Crushed andricus kollari wasp galls are crushed and mixed with water, then added to crushed iron sulphate and gum Arabic to produce a cost effective and extremely long lasting ink. This specific type of ink is the most important ink used during the last 1000 years of European and subsequently western history as its indelible and essentially ever lasting whether just written or having been dried for hundreds of years. This incredible ink was used to write the Magna Carta and the American Declaration of Independence, has brought forth the recorded musical genius of Wolfgang Amadeus Mozart and Johann Sebastian Bach, was used to produce the artwork of Rembrandt Harmenszoon van Rijn and Leonardo da Vinci, and was utilized to produce the theories of Sir Isaac Newton and Charles Darwin

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

2 Comments

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
