The Largest Mass Extinction of Life Upon Earth

Leave a comment

There have been 5 mass extinctions throughout Earth’s tumultuous history. 99.9% of all species which have ever lived on Earth have gone extinct. 252,000,000 (252 million) years ago, Earth suddenly turned toxic to life. Nearly 96% of species worldwide, rapidly became extinct, a period referred to as the “Permian-Triassic Extinction Event”, and less often called the “Great Dying”. This mass extinction was caused by the eruption of super volcanos, leading to the land drying up, the ocean acidifying, every forest dying, and nearly all plant life perishing. Everything alive today is descended from the species which made it through this age

The Belief of How Insects Spawned Within Europe During the 18th Century

Leave a comment

It was primarily believed within Europe during the 18th century that insects were correlated with the devil, as anything not understood or relatively misunderstood during the period was explained as evil or demonic phenomena in nature powered by supernatural forces. Scientific knowledge was limited during the 18th century, therefore superstitious beliefs were commonplace throughout the whole of Europe. Europeans believed that insects spawned from the mud annually, because they could not explain why insects develop en masse and are only present for the warmer months of the year, with this hypothesis referred to as “spontaneous generation”. This theory was only laid to rest after the theory of spontaneous generation was challenged by several scientists including Italian physician Francesco Redi, who conducted experiments during the 17th century which demonstrated that maggots decaying upon meat arise from eggs laid by flies, not from the meat itself. During the 18th century, Italian priest and biologist Lazzaro Spallanzani conducted further experiments which refuted spontaneous generation, particularly for microorganisms

The Etymology of “Curry Powder”

Leave a comment

The term “kaṟi”, referred to during the modern day as “curry”, is described within a mid 17th century Portuguese cookbook entitled the “East Indian Cookery Book” which was written by members of the British East India Company who traded with Tamil merchants along the Coromandel Coast of southeast India. Curry powder is referred to as such because one of the spice blends in the book which contains 2 or more spices is referred to as “kari podi” which has been Romanized to read as “curry powder”

The Accidental Discovery of Tea and the Agricultural Advents Developed by Chinese Emperor Jiang Shinian

Leave a comment

Tea was discovered entirely by accident. The first emperor of ancient China, Emperor Jiang Shinian (Shen Nung or Shennong) was boiling water in his palace courtyard when a tea leaf fell from above, and into the boiling pot. Due to the pleasant scent, Jiang ingested the water as it cooled and by coincidence discovered the activity of tea consumption. The name Jiang Shinian directly translates to mean “Devine Husbandman” within Mandarin, as it is believed Jiang developed multiple Chinese agricultural advents (e.g. crop cultivation for medicinal herbs, soil managment strategies, irrigation etc.). It should be noted, this account of the discovery of tea is believed to most likely be fictitious and mythological in origin by Chinese historians during the modern day

The Development of Japanese Tea Gardens and Tea Houses

1 Comment

The Japanese tea garden is the antithesis of the Buddhist Zen garden and originated in the 9th century after tea was imported into Japan from China. Buddhist monks would drink Chinese tea to keep themselves awake during long meditation sessions. Over the subsequent centuries, tea drinking became an elaborate practice which was highly ritualized with samurai, geishas, and monks all serving tea using these same concepts. Japanese tea gardens developed during the 16th century with direct influence from the concepts of tea ceremonies, designed and constructed to surround tea houses

The Origin of the Tradition of Bringing Christmas Trees Indoors

Leave a comment

During the Ancient Roman Saturnalia festival near the winter solstice, coniferous branches, boughs, and trees were brought indoors and kept. Although the exact rationale is debated, the concept may have developed as a means to symbolize everlasting life and/or as a method to ensure the god Saturn, the patron deity of time, wealth, and agriculture among other things within Ancient Rome, would prolong summer and shorten winter. In the 4th century A.D. this festival was replaced by the Christian holiday of Christmas which adopted the practice of bringing trees indoors as well. It should be noted, bringing coniferous trees indoors during the winter solstice was a pagan tradition throughout the northern hemisphere, with multiple cultures and empires outside of the Ancient Romans adopting the practice

The Fallacy of Moss Always Growing Upon the North Side of Trees

1 Comment

Moss does not only grow on the north side of trees, as it is commonly believed by many. Moss typically grows on the north side but this rule only applies in the northern hemisphere. In the southern hemisphere, moss mostly grows on the south side of trees. The reason for this inversion is that in the northern hemisphere, because of the tilt of the Earth on its axis, the sun almost always appears to be a little south of directly overhead. That’s why rooms with windows facing south are brighter than rooms with windows facing north. This is important for moss because the north sides of trees within the northern hemisphere are shadier and therefore wetter. The south sides of trees get more sunlight, so water evaporates faster there

U.S. Presidents Who Participated Within the Practice of Slavery

2 Comments

10 of the first 12 U.S. presidents owned slaves, with the only exclusions being the 2nd president John Adams and the 6th president John Quincy Adams, the son of John Adams. George Washington owned an estimated 200 – 600+ slaves, Thomas Jefferson owned an estimated 200 – 600+ slaves, and Zachary Taylor owned an estimated 300 slaves. The U.S. president with the least number of slaves, not including presidents who did not own slaves, is a tie between the 8th president, Martin Van Buren and the 18th US president, Ulysses S. Grant, each owning one slave. It should be noted, 12 U.S. presidents owned slaves at some point in their lives, however of these 12, 8 owned slaves while in office. The last U.S. president to participate within slavery whilst still in office was Zachary Taylor, and the last U.S. president to own an enslaved person at any time was Ulysses S. Grant. The last person enslaved by a U.S. president was William Andrew Johnson, who was enslaved by the 17th U.S. president, Andrew Johnson. It is believed that Johnson paid $500.00 for William Andrew Johnson’s mother, which equates to $19,348.46 as of 2023 when accounting for inflation using the base year of 1850, 10 years after Johnson’s first slave purchase and 15 years before he became president of the U.S.

The Reason Most Cats Adore Cat Nip

Leave a comment

Catnip is a perennial herb which is a member of the mint family, specifically the species of the genus Nepeta (pronounced “nah-pee-tah”) in the family Lamiaceae (pronounced “lah-me-yay-see-aye”). The chemical compound in the nepeta cataria plant which attracts and affects felines is nepetalactone (pronounced “nah-pee-tal-ack-tone”). Nepetalactone is indigenous to Southern and Eastern Europe, the Middle East, Central Asia, and parts of China. When cats consume catnip orally the compound acts as a sedative, but when inhaled for its scent, it causes short bursts of hyperactivity. Nepetalactone is extracted via steam distillation and acts as a natural mosquito and fly repellent. Several scientific studies have demonstrated that leopards, cougars, and various species of lynx often react to catnip in a similar manner to their domestic house cat cousins, whilst lions and tigers may react strongly, but may also have little or no reaction whatsoever. 33% of cats are unaffected by catnip with the behavior theorized to be hereditary in nature. In 1962, it was discovered that susceptibility to catnip may be directly related to the Mendelian-dominant gene. Other plants can have similar effects upon felines including the roots and leafs of the valerian plant, silver vine which is sometimes referred to as “matatabi”, and Tatarian honeysuckle wood. Cats who do not respond to nepeta cataria are more likely to respond to one, some, or all of these alternatives plants. In addition to its use with cats, nepeta cataria is also a popular ingredient in herbal tisanes and teas, and is highly valued for its sedative and relaxant properties”

The Etymology of Palm Sunday

Palm Sunday is named as such because as Jesus Christ approached the city of Jerusalem, Israel, a large crowd welcomed him by waving palm fronds and shouting “Hosanna! Hosanna in the highest!”
