The Origin of the Weekend for Workers

Leave a comment

The weekend was invented in the 19th century in Marseille, France (pronounced “mar-say”) as part of a broader societal shift during the Industrial Revolution. During the period, workers within factories and shipyards were often laboring 6 – 7 days per week, with little rest in between shifts. Because Marseille had a bustling port with a strong labor movement and  growing working class, reformers and unions began to push for a scheduled rest day for leisure and recovery. By the mid 19th century, experiments of giving workers Saturday afternoons off began to spread rapidly, which permitted workers more time for their families, religious observance(s), and day to day community life. This practice gradually evolved into the 2 day weekend, beginning in France and then being disseminated across Europe and North America. World governments and industries permitted this shift to occur because it became understood that rest improved productivity and overall job satisfaction

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 First Person to Publish an Encyclopedia

Leave a comment

Naturalis Historia was the first compiled collection of writing, which during the modern day would be referred to as an “encyclopedia.” Written by Pliny the Elder in the 1st century A.D., Naturalis Historia was divided into 37 unique books and contained more than 20,000 individual facts. Naturalis Historia was comprised of a vast array of subjects including astronomy, geography, zoology, botany, medicine, and even artwork, making it one of the most ambitious attempts in history to catalog and consolidate the entirety of human knowledge. Unlike earlier publications which often focused upon a singular discipline (e.g. medicine but not science or law but not ethics etc.), Pliny the Elder’s Naturalis Historia compilation sought to collect and streamline the entirety of the natural world and the human understanding of it into a single reference point. Pliny the Elder’s encyclopedic vision influenced scholars for centuries after his death, and his work served as one of the main pillars of Medieval and Renaissance education in the centuries which followed. Shortly after completing this compendium in 77 A.D., Pliny the Elder died during the eruption of Mount Vesuvius in 79 A.D. at age 55 whilst attempting to rescue those who could not escape from the volcano’s clutch. Fortunately, the entirety of his Naturalis Historia work survived this natural disaster

The Reason the Earth Becomes Colder When Closest to the Sun

5 Comments

The Earth orbits the Sun in an elliptical path, meaning the distance between each body constantly fluctuates. Perihelion is the specific point in this orbit at which the Earth is closest to the Sun with this phenomena occurring near January 3rd annually. In contrast to this, aphelion, is when the Sun is at its farthest distance from the Earth, which occurs in July each year. Interestingly and counterintuitively, the Earth is coldest during its perihelion phase (when the sun is closest to the Earth) and warmest during aphelion (when the sun is furthest from the Earth). This paradox occurs because of the struggle between orbital distance and the 23.5 degree axial tilt of the Earth. Whilst the Earth is slightly closer to the Sun during the perihelion phase in early January, receiving 6% – 7% more solar energy than in July, the Northern Hemisphere is tilted away from the Sun which forces sunlight to strike the Earth’s ground at a more shallow angle, therefore spreading the light over a larger surface area and filtering it through more of the atmosphere. This reduction in heat overrides the slight shift of the Earth and Sun being closer or further away, as it is the tilt of the Earth, not the orbital proximity of the Sun which dictates both the 4 seasons as well as the perihelion/aphelion paradox. It should be noted, global temperatures peak in July because the Northern Hemisphere Continental Crust heats more rapidly than the Southern Hemispheres oceans

The Number of Gifts Santa Claus and the Elves Must Build and Deliver Each Christmas Eve

5 Comments

Assuming Santa Claus delivers at least 1 gift to each child worldwide, this would equate to 2,100,000,000 (2.1 billion) gifts. With an average of 2.5 children per household worldwide, Claus would have to visit 840,000,000 (840 million) homes to accomplish this task. To finish this job in 24 hours (12 for each side of the world), Claus would need to visit 35,000,000 (35 million) homes per hour which would be 580,000 per minute, or nearly 10,000 every second! Because there are so many homes and so very many children, the elves of the North Pole face an equally grueling pace. Assuming each child receives 1 toy, and the build time is spread across 364 days, these elves would need to craft approximately 5,750,000 (5.75 million) toys per day. This would mean 240,000 toys per hour, 4,000 per minute, or nearly 70 every second without a work break for any of them. If the North Pole were to employ 100 elves, each would need to make 0.7 toys per second; and with a large company of 1000 elves, this value drops to 1 toy every 14 seconds which is more manageable; however with a massive company of 10,000 elves, each would only need to craft 1 toy every 2.5 minutes which would be much more probable for a workforce to achieve; if however the North Pole were capable of managing a city sized work force of 100,000 elves, each elf would need only to craft a single toy every 24 minutes which is a pace that a human powered North Pole, theoretically could handle. With that being said, mythologically speaking elves are immortal, or at the very least ageless, and they do possess arcane magic and clandestine knowledge which must be kept in mind when calculating what is theoretically possible

The Origin of Life Upon Earth

Deoxyribonucleic acid (DNA) is most likely not the first building block of life because of its complicated double helix pattern. Ribonucleic acid (RNA) is also statistically unlikely because although it is only half as complex as deoxyribonucleic acid being that it does not resemble a double helix structure, but rather a single helix structure, it would have required 5 specific sugar molecules to spontaneously bind together, one by one, in a very specific order. Threose nucleic acid (TNA) however, would only require 4 identical simple sugar molecules to spontaneously, come together. This is theoretically the most probable candidate for being the first spark of life. Threose nucleic acid can easily base pair and exchange genetic information with ribonucleic acid making it the best blueprint which would have shown up long before the complex cellular machinery, which is found within all living cells today

The 4 Primary Preservative Agents Used During Ancient Egyptian Mummification

Leave a comment

The 4 main chemicals used by the Ancient Egyptians for mummification were natron as a drying agent, palm wine to cleanse the body and its cavities after organ removal, cedar oil to anoint, and bitumen as a glue. Natron is a naturally occurring mineral mixture primarily composed of sodium carbonate decahydrate and sodium bicarbonate, with traces of sodium chloride and sodium sulfate, and is harvested from dry lake beds (e.g. Wadi Natrun etc.). Natron’s high alkalinity and hygroscopic properties allow it to desiccate human remains by drawing out moisture, whilst simultaneously inhibiting bacterial growth and chemically breaking down lipids. Beyond preservation, natron also symbolized ritual purification and was used ubiquitously within Ancient Egypt (e.g. religious ceremonies, glass manufacturing, personal hygiene etc.). Palm wine, a fermented beverage comprised of the sap of date palms, was highly valued for its antiseptic and moderate alcoholic properties throughout history within Egypt. During mummification, wt/wety (pronounced “weh-tee”) the Ancient Egyptian term for “embalmers”, used palm wine to rinse the thoracic and abdominal cavities, ensuring that residual organic tissue was sterilized and virtually all odors eliminated. This cleansing was often accompanied by aromatic herbs and spices, believed to be used for both hygiene as well as ritual purification, reflecting the Ancient Egyptian ideological concern for both physical preservation and symbolic purification of the vessel for the soul. Cedar oil, a bit of a misnomer as it was often derived from juniper or other closely related coniferous tree sources rather than the cedar tree itself, was prized for its resinous, aromatic, and antimicrobial characteristics. Cedar oil was applied as an anointing oil to both the skin and the ḥbsw/ḥebesw (pronounced “heh-bes-oo”), which means “bandages” in the Late Egyptian language, but more literally translates to “wrappings”, both to soften and preserve tissues but also to imbue human remains with the fragrance of soil/wood, smoke, and camphor; scents associated with the pantheon of Egyptian deities. For those who could not afford this preservation method, cedar oil could be injected into the body cavity directly, in which its solvent properties dissolved soft tissues, leaving only skin and bone once the natron had absorbed the liquefied remains, raised the overall pH level to halt decomposition, and dried the cavity completely. Lastly bitumen was used, a naturally occurring petroleum product also referred to as “natural asphalt”, which was a black, viscous substance sourced from various geological deposits within the region (eg. the Dead Sea etc.). Although not universally used throughout all dynasties of the Ancient Egyptian state, bitumen became increasingly common in the most recent phases of Ancient Egyptian history, particularly during the Greco Roman period from 332 B.C. – 642 A.D. Bitumen’s adhesive and waterproofing capabilities allowed it to bind wrappings and seal the body shut, and its dark coloration may have been deliberately chosen to evoke Osiris, the Ancient Egyptian god of the underworld, often depicted with black skin and symbolizing both fertility and rebirth. Additionally, in terms of chemical composition, bitumen provided durability to the embalming balms used, with modern day analyses revealing it was typically blended with resins, lipids, and waxes rather than used in its most pure form

The Hottest Natural and Artificial Temperature in the Universe

Leave a comment

The hottest temperature ever measured and/or observed was within the Large Hadron Collider located on the border of Switzerland and France. When lead particles are smashed together within this particle accelerator, for a split second the temperature reaches 4,000,000,000,000 (4 trillion) degrees Celsius which is hotter than a supernova explosion, albeit the theoretical maximum possible temperature of the universe is believed to be 20 orders of magnitude greater. Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has a value of 1.416785(71)×1032 kelvin. Temperatures above this are believed to be physically impossible because as particle energies become larger and larger, the gravitational forces between them inevitably become as strong as the other 3 fundamental forces which essentially boils and breaks down both the universe and space time. Outside of laboratory conditions however, the hottest naturally occurring place within the universe is the quasar 3C273 (the 273rd entry in the Third Cambridge Catalogue of Radio Sources), a blazing region surrounding a supermassive black hole approximately 2,400,000,000 (2.4 billion) light years away from the Earth, with matter within its accretion disk being measured at temperatures of approximately 10,000,000,000,000 (10 trillion) kelvin, making it far hotter than the core of any star, and 400,000x hotter than the core of the sun, rivaling the conditions of the universe right after the Big Bang

The Coldest Natural and Artificial Temperature in the Universe

Leave a comment

The coldest temperature ever measured and/or observed was within a controlled laboratory experiment in Germany; an experiment entitled “Time‑Domain Matter‑Wave Lens System for Atomic Clouds”. During this experiment, physicists cooled a cloud of rubidium atoms to 0.000000000038 (38 trillionths) of 1 degree above absolute zero which is -273.15 degrees Celsius, colder than the vacuum of space, slowing these atoms to a near motionless state for a very short period of time which created a fleeting state of matter existing closer to perfect stillness than anywhere or anything else within the universe. This experiment was the closest scientists have come to achieving complete absence of motion within a controlled setting. Contemporary models of physical cosmology postulate that the theoretical minimum possible temperature is absolute zero, which has a value of 0 kelvin. Temperatures below this are believed to be physically impossible because particle energies become so tiny that all molecular motion ceases to continue functioning, allowing quantum effects to dominate, and producing exotic states of matter (e.g. Bose-Einstein condensates in which matter behaves as a single quantum entity etc.). The coldest naturally occurring place within the universe is the Boomerang Nebula, a dying star cloud located approximately 5,000 light years away from the Earth. The Boomerang Nebula has been measured at 1 degree above absolute zero, making it even colder than the faint afterglow of the Big Bang itself, yet the Time‑Domain Matter‑Wave Lens System for Atomic Cloud experiment is 26,000,000,000x (26 billion) colder and closer to absolute zero than the Boomerang Nebula or any other naturally occurring region with low heat

The Mathematical Probability of Miracles

Leave a comment


Many would argue that miracles have a 1:1,000,000 (1 to 1 million) ratio, and others whom are more conservative would argue that miracles have a 1:1,000,000,000 (1 to 1 billion) ratio, meaning for every 1 miracle, 1,000,000,000 (1 billion) events occur without a miracle. 1 in 1,000,000,000 (1 billion) sounds astronomically high, as on the entire planet there are only 8,100,000,000 (8.1 billion) human beings, but if a person draws 6 cards from a standard deck of cards, whatever sequence they draw has a 1:14,000,000,000 (1 in 14 billion) chance of occurring. Because of this, one could argue that every hand of cards drawn is a miracle and not a random act of chance. This logic applies to all randomized items or numerical values (e.g. first 6 digits of a Social Insurance Number or last 6 digits of a phone number etc.). What humans refer to as a “miracle” is often merely a statistical anomaly, an event with low probability, but not impossibility, something which is guaranteed to occur given enough repetitions are made. The sheer volume of possible outcomes virtually guarantees that rare patterns will emerge eventually, not because they are miraculous, but because the mathematics demand it be so
