How Japanese Fishers Used Sumi Ink to Document Their Trophy Catches During the 19th Century

Leave a comment

In Japan, there is a traditional art medium referred to as “Gyotaku” (pronounced “gyoo-tah-koo”), which means “fish impression” in Japanese. The art form began in the 1800’s when fishers wanted to record their prized catches before the development of photography. These fishers would coat their most prized catches in sumi ink, press the inked fish onto washi paper, and this create a highly detailed and ornate print which demonstrates the fish’s size and features at a 1:1 scale. The ink relies upon pure collagen, manufactured by simmering raw animal tissue for hours at a temperature range of 60 – 65 degrees Celsius, until such time that the protein of the tissue dissolves into a clear liquid adhesive. Once this occurs, the organic solution is mixed with ultra finely compacted soot pigment, creating a rich and viscous ink to produce prints from

The Fallacy of Airplane Mode Disabling the Global Positioning System Tracking of Smartphones

Leave a comment

Even when Airplane Mode is activated, the Apple iPhone still receives signals from the global positioning system because this apparatus is a passive, receive only system which does not rely upon a cellular connection, WiFi connection, and/or Bluetooth connection to function. The iPhone scans and listens for satellites orbiting the Earth and calculates its relative position based upon this timing data, which means the iPhone can still determine a users location even without an internet connection, however if this is not desirable by the end user, Location Services can be disabled which theoretically turns this function off. This information is true for most modern smartphones including Android, however not all (e.g. smartphones manufactured prior to 2010, minimalistic/budget conscious smartphone designs, smartphones with custom firmware and/or enterprise restrictions like those managed by corporate information technology teams or running custom read only memory etc.)

The Fermentation and Manufacturing Process of Ancient Roman Garum (Fish Sauce)

Leave a comment

The Ancient Roman’s created a special fermented fish sauce called “garum”. Garum was highly valuable and in modern times accounting for inflation, garum would cost $1250.00 for 1 liter. Garum was made from nothing more than salt and decayed fish. The original preparation is unknown as the ancient recipes have been lost. The fishes organs and digestive fluids help in the fermentation process. The container which the garum is made in is left in the sun for a few days to allow the process to ferment as much as possible. The oily slush oozing from the fishes organs and digestive enzymes is the garum and it is loaded with nutrients and contains glutamate which triggers chemical receptors on the tongue to make the brain crave more of it. Glutamate is the primary ingredient/component in monosodium glutamate, commonly abbreviated as “MSG”, and is used by many chefs all over the world

The Lush Forests of Australia and Antarctica During the Mesozoic Period and the Reason Antarctica Became Cold

Leave a comment

Both Australia and Antarctica were once fused together as part of the supercontinent Gondwana, neither being an arid and hot landscape nor a cold desert but instead a vast and lush forest, larger than the Amazon Rainforest, spanning thousands of kilometers in size. The reason Antarctica is no longer temperate and forested is because in contrast to most shorelines which disrupt and disperse ocean currents upon contact with the coastline, the waters around Antarctica encircle it unobstructed, forming the Antarctic Circumpolar Current after the Drake Passage opened 34,000,000 (34 million) years ago. Because there is no land to stop this flow of water, it forces the current to become stronger and deeper over time. The Antarctic Circumpolar Current cut the continent of Antarctica off from the warm waters of the north, a thermal isolation further exacerbated by decreasing carbon dioxide levels over millions of years. In a mere 1,000,000 (1 million) years during a rapid cooling phase, although the full shift took tens of millions of years to complete, Antarctica transitioned from an appearance which resembled Australia during its wetter, forested period of the Cenozoic Era, to become a frozen tundra, virtually uninhabitable by humans until the mid 20th century, due to its subzero temperatures which consistently remain far below any other location upon Earth, as well as being locked in by vast ice sheets which formed 14,000,000 (14 million) years ago

The First Human Beings to Migrate to North America

1 Comment

The first people to arrive in North America are suspected to have arrived 15,800 years ago. Sea levels were much lower because of polar ice caps being frozen, which allowed modern day Siberia and Alaska, United States of America, to be connected. How migration occurred is still debated, with some scholars hypothesizing that walking whilst hunting large mammals was the most likely way, while others propose that the indigenous people of North America hunted along the shoreline using maritime skill sets and travel vehicles. 10,000 years ago, the ice sheets receded northbound allowing for civilizations to domesticate northern British Columbia, Canada

The Reason Life Upon Earth Migrated From the Ocean Onto Land

Leave a comment

Billions of years ago when the first living organisms started harnessing the energy of the sun through photosynthesis, they began producing a waste product which was oxygen. When oxygen rises high up into the atmosphere, it transforms into ozone which is why the Earth has a thin protective layer of ozone which alongside the magnetic field, helps protect the Earth from the violent ultraviolet radiation spewed out by the sun. As plants, microbes, and fungi migrated from the water to land, even more oxygen was produced, extending the ozone layer to become much more formidable. This was the catalyst for life migrating onto dry land which occurred 450,000,000 – 500,000,000 (450 million – 500 million) years ago during the Paleozoic Era, specifically during the Ordovician and Silurian periods

Italian Explorer Christopher Columbus Leveraging Astronomy to Manipulate the Indigenous Taíno of Jamaica

Leave a comment

During Italian explorer Christopher Columbus’ 4th voyage and while still stationed upon the island of Jamaica in the Caribbean, Columbus’ crew and flotilla did not have the supplies necessary to travel back to Europe. Columbus appealed to the indigenous Taíno people of the island and requested they share their resources. The Taíno informed Columbus that they had only sourced enough supplies to see themselves through the season and that they did not have access to a surplus. Columbus responded by telling this group that if they did not comply, he would summon divine forces and cause the moon to disappear within 1 weeks time; the key to this being that Columbus understood that a total lunar eclipse was scheduled to occur within the coming week. The Taíno were skeptical of this claim initially, but when a total lunar eclipse occurred as predicted, it caused this group to believe that Columbus held a seat beside the hand of God. Unsurprisingly, Columbus was almost immediately provided all of the material he desired to fund his return voyage to Europe. During the middle of the total lunar eclipse, Columbus stated that his god, the Christian God, would now reverse the destruction of the moon and return the moon to its former position as the Taíno had complied with his crews demands

The Correlation Between Cats and the Bubonic Plague of Europe

Leave a comment

During the Middle Ages and up until the Salem Witch Trials, cats were killed alongside their owners who were believed to be practicing the dark arts of magic, sorcery, and witchcraft. Typically cats were burned alive in ceremonial bonfires. Ironically, had this not occurred, the Bubonic Plague probably wouldn’t have been as prolific as it was as the fleas found upon the rats who carried the disease, would have been killed alongside their host by the very cats which were killed in droves by human beings. Cats are partially resistant to the Bubonic Plague but with few to keep the rat population in check, the plague was able to wash over Europe and kill 25,000,000 (25 million) people which was 25% of the European population

The Center of the World and the Reason It Will Not Exist During the 22nd Century

Leave a comment

Kiribati (pronounced “kir-ah-bas”) in the Pacific Ocean is in the center of the world because it is the only country which is in the Northern and Southern Hemisphere as well as the east and the west of the International Date Line; no other country has that designation. Kiribati is located upon the equator, which historically has been devoid of cyclones, however global weather patterns are shifting due to climate change and the equatorial zone is now subject to the path of cyclones. Climate predictions have definitively and conclusively demonstrated that Kiribati will be completely submerged beneath the ocean by the end of the 21st century

The Reason the Coriolis Force Does Not Affect the Way Water Flows Within Drainage

Leave a comment

Both clockwise and counterclockwise flowing drains can be found regardless of the hemisphere in which they are observed. The Coriolis force is too weak to affect such small bodies of water, which is why this occurs. The effect is more measurably observed in large bodies of water like the ocean which is where hurricanes and typhoons begin to emerge. The reason the Coriolis effect takes place is because of the northern and southern pole. If observed from the northern pole, the Earth rotates counterclockwise however when viewed from the southern pole, the Earth appears to rotate clockwise. The analogy of a spinning disc helps to illustrate this image. From the top, a disc appears to spin clockwise as it plays the content stored upon it, but if viewed from below, that same disc would appear to the observer as if rotating counter clockwise
