The Reason Japanese Samurai Shave the Top of Their Head

Leave a comment

The practice of “chonmage” (pronounced “chon-mah-geh”) which means “tied knot on top” in Japanese is the reason Japanese samurai shaved the tops of their heads, in a pattern reminiscent of male pattern baldness. Japanese Samurai shaved the top of their heads in this particular style for both pragmatic and symbolic reasons. The shaved portion of the head helped secure their helmets referred to as “kabuto” which means “helmet” in Japanese, making them more comfortable but also prevented overheating during battle. Over time, the chonmage became a status symbol within Japanese society, symbolically representing a samurai’s loyalty and discipline. The chonmage aesthetic also reflected the samurai’s adherence to Bushido, the warrior code. Different variations of chonmage emerged within Japan over the centuries, with the style remaining a distinctive hallmark of the samurai class until the Meiji Restoration in 1868 when Japan modernized and abolished the traditional feudal samurai system

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 Volatile Temperament of Jesus Christ

Leave a comment
Jesus Christ was known to be confrontational when his message was not being understood correctly. Christ was not adverse to conflict and was not as mild and reconciling as he is portrayed during the modern day, in fact there are accounts in which he cursed fig trees for not bearing any fruit and cursed entire locations for not responding to his message, after which he continued to migrate with his congregation, effectively leaving those people behind instead of persisting to convince them of his teachings. The Gospels account for instances like this multiple times throughout their recounts

The Development of Lock Hospitals Within England for Female Sex Workers During the 19th Century

Leave a comment

Due to the fact that sexually transmitted infections and diseases were rampant among English soldiers, in 1864 novel legislation entitled the Contagious Diseases Act was passed which permitted any woman suspected of prostitution as young as 13 years of age, to be forcibly examined by a physician. Institutions referred to as “lock hospitals” were established and setup so that women suspected of spreading disease could be detained and examined, and if they were positive in their evaluation, they could then be incarcerated for up to 3 months. It never occurred however to the English government that men could also spread sexually transmitted infections and diseases which is why men were immune from this legislation and a key reason as to why the problem was never resolved. Because of this, in 1886, this legislation was repealed

The Insect Used to Produce Ink Throughout History

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

How Flames Were Artificially Produced for Opera Productions During the 18th Century

Leave a comment

During the 18th century within opera and theater productions, stage doors which would lead a character to Hell achieved simulating the flames of Hell with brandy which would be placed into a container and lit on fire due to the fact that during the period, brandy was the brightest glowing flame available because of it’s high alcohol content. Once the brandy was burning bright, a powder referred to as “lycopodium” was blown across the flames to create an intense illumination, creating a fireball of sorts. It was in truth a very dangerous special effect to achieve because of the wooden sets, the actors involved, and the enclosure of the theatre itself. Most of those who performed the pyrotechnics for operas and plays during this period were ex-military, often soldiers who understood how these chemicals worked in depth as rocket technology was at the cutting edge of warfare during the era

The Toxicity of Tanneries During the French Revolution

Leave a comment

One of the largest contributors to pollution during the French Revolution was the work of tanneries, which converted what is essentially animal skin, into leather goods. First the hide was immersed in an alkaline lime and water solution for up to 3 weeks, then it was brought out and shaved for both the hair on one side of the hide and the dissolved fat referred to as “sinew” on the other side. Once this process had been complete, dog and bird feces were mixed with hot water and human urine to create a bacterial cocktail which would work together to soften the hide and help it absorb dye. All of these components were dumped into local water sources once they had served their purpose which made living around them nearly impossible, with many people developing ulcerative lesions upon their throats when around these ingredients for extended periods of time

Scientists Who Studied the Sun by Looking Directly at it

Leave a comment

Thomas Harriot observed sunspots in 1610 but did not publish his work. In 1612 Harriot recorded that after having viewed the sun, his sight was “dim for an hour”. Oxford University astronomer John Greaves is quoted as stating that after sun observations, he would see afterimages which looked like a flock of crows within his field of vision. Sir Isaac Newton attempted to look at the sun in a mirror, which blinded him for 3 days and caused him to experience afterimages for months

Bakers and Grocers Using Additives to Increase Profit Margins During the Victorian Period

Leave a comment

Profit margins were incredibly thin for Victorian bakers so to stretch flour as far as possible, they would add all sorts of additives to adulterate the end product (e.g. clay, plaster of Paris, sawdust, chalk, and alum, the same chemical used to clean swimming pools during the modern day etc.). Alum had both bulking qualities and acted as a bleach for the flour, so alum despite it being the most dangerous additive, was also the most popular supplement during this period. Victorian grocers would use tactics like watering down milk to stretch it as far as possible, going even further than bakers when it came to food tampering. Grocers would often add red lead to cheeses like Red Gloucester cheese, add iron sulfate to pickles to make them appear more green, spruce up old vinegar by adding sulphuric acid, add poisonous Prussian blue to tea leaves, and mixed mercury with children’s candy to enhance its color

The Industries Disrupted by U.S. Entrepreneur Steve Jobs and U.S. Inventor Thomas Edison

Leave a comment

Steve Jobs affected and subsequently disrupted the computer industry, the motion picture industry, the music industry, and the telecommunucations industry, all within a single lifespan. This achievement places Jobs at the status of a world renowned icon, a person like Thomas Edison who affected all of the same industries as well, swapping only the computer industry for the electric industry. Edison invented the incandescent light bulb for the electric industry, the phonograph for the music industry, and the motion picture camera for the film industry, and improved the telegraph and telephone for the telecommunications industry. Jobs developed the Macintosh computer for the computer industry, the animation studio Pixar for the film industry, the iPod and iTunes for the music industry, and the iPhone for the telecommunications industry
