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

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 Status Symbol of Keys Within the Ancient Roman Empire

2 Comments

Metal keys first appeared during the Ancient Roman Empire and were viewed and often flaunted during the period as an indicator of wealth and/or elevated social status, as Ancient Roman keys were typically comprised of bronze or iron, occasionally worn as decorative jewelry (e.g. rings, bracelets, belt attachments etc.), and used primarily to secure high value items (e.g. jewelry boxes, document cases, coin chests etc.) making them both functional tools but also visible reminders of social status and income. Because only the wealthy could afford metal keys within the Ancient Roman Empire, lower socioeconomic classes relied upon more simplistic, wooden lock mechanisms and in many cases left valuable possessions unsecured entirely. Some Ancient Roman keys featured intricate designs (e.g. animal motifs and geometric patterns etc.), personalized and designed to reflect the predilections of the owner of the key and the lock it is designed for. The Latin term for key, which is “clavis”, evolved and came to mean “code” or “solution” over time, which is notable because it demonstrates the period when physical access and security and intellectual access and security became conceptually correlated with one another. Archaeologists and historians have recovered metal keys from Ancient Roman villas, balneae (pronounced “bahl-neh-eye”) which are bathhouses, and burial sites, often discovered alongside personal items (e.g. grooming tools, coins, small religious tokens etc.). The modern day concept of personal security and having exclusive access to one’s belongings and/or information traces its origins back to these early locking mechanisms and keys as what began as a practical intervention for safeguarding valuables laid the foundation for the modern day systems of privacy, ownership, and controlled access to sensitive and/or valuable information or objects

The Advent of the Ancient Egyptian Clepsydra (Water Clock)

Leave a comment

The Clepsydra (pronounced “clep-see-drah”), more commonly referred to as the “water clock”, was among the earliest technological devices engineered for measuring time, predating mechanical clocks by over a millennia. The earliest known example of a clepsydra is from Ancient Egypt, constructed close to 1400 B.C., and attributed to an Egyptian court official named “Amenemhet” (pronounced “ah-men-ehm-het”). Clepsydra clocks operated using 1 of 2 primary designs; which includes both outflow and inflow setups. In an outflow clepsydra, water exited the chamber container through a small hole at the bottom, and the measurement of time was tracked by the continually lowered water level which was measured against internal markings. Inflow clepsydras reversed this design setup with water entering a marked container vessel, and the continually rising water level indicating the amount of time which had elapsed. The main challenge of the inflow and outflow designs was maintaining a consistent flow rate of water because as water drained, pressure dropped which slowed the drip rate and skewed the clocks accuracy. Ancient Greek engineer Ctesibius (pronounced “teh-sib-ee-us”) addressed this problem by introducing an overflow tank with a fixed water level, ensuring constant pressure and uniform water flow at all times. Ctesibius also added a float regulated valve system, an early feedback mechanism designed to stabilize inflow of water and prevent overflow, much the same as the float controlled fill valve (e.g. ballcock, float cup valve, diaphragm type inlet valve etc.) installed within toilets during the modern day. Subsequent future cepsydra designs implemented gears and escape mechanisms to convert water movement into mechanical energy/motion. Chinese engineers expanded further upon the concept of the clepsydra by introducing polyvascular systems, in which water flowed through multiple containment vessels in an effort to better regulate timing intervals. These innovations permitted water clocks to function independently of sunlight unlike sundials, the prevailing time keeping technology throughout history, and laid the foundation for regulated mechanical timekeeping which proceeded it. Despite limitations (e.g. temperature dependent viscosity, leakage and evaporation, the need for constant manual maintenance by human beings etc.), clepsydras remained in use for centuries and were the first controlled, replicable timekeeping systems in history only falling out of fashion during the late Middle Ages due to the ascendency of mechanical, pendulum and gear based clocks

The Period When Human Begins Developed a Throw Away Cultural Mindset

Leave a comment

Human beings have arguably been a throw away culture, or at the very least mindset and culture, since 1892 when bottle caps were first introduced. The trend has become more and more prevalent to the point where we now replace an entire transmission rather than a gasket. This shift reflects the rise of planned obsolescence, in which products are intentionally designed to have limited lifespans and/or be extremely difficult or expensive to repair. As manufacturing has become cheaper and mass production more efficient, the economic incentive to discard and replace overtook the values of maintenance and longevity. In all industries (eg. electronics, automotive, fashion etc.), repair has been sidelined in favor of convenience and profit. The result is a global surge in waste, with millions of tons of usable materials ending up in landfills each year. Fortunately, there is an expanding movement advocating for the right to repair one’s own possessions which is now acting as a counterbalance to this disposable mindset

The Origin of Google’s Name

Leave a comment

Google’s original name was “BackRub”, a reference to its early algorithm which analyzed backlinks to assess their importance. Backlinks are the hyperlinks pointing to webpages on the internet (e.g. navigation from one website to another etc.). Developed at Stanford University in 1996 by Larry Page and Sergey Brin, BackRub laid the foundation for PageRank, the ranking system which would later power the Google search engine. As the project matured, Page and Brin began to recognize and understand that the name BackRub did not reflect the vast scope of their ambitions for the company as the duo wanted a name that could capture the enormity of the data their engine could and eventually would process. This is why the name “Google” was chosen in 1997. Interestingly, during a domain search for “googol.com”, a mathematical term which represents 10¹⁰⁰ (10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 or 1 with 100 0’s after it) the friend who registered the domain name for Page and Brin accidentally typed “google.com” instead of “googol.com”. Originally this was an error but Page and Brin believed the misspelling to be simpler, more memorable, and visually cleaner therefore deciding to keep the name as it was

The Origin of Uppercase and Lowercase Letters and the Influence of Typesetting Upon the English Language

Leave a comment

The term “uppercase” and “lowercase” in relation to alphabet letters was derived during the Victorian period within England. Advertising was highly prominent during the 19th century and used ubiquitously by businesses. The poster makers who would serve these businesses would use letters which were essentially stamps, dipped into thick, viscous, oily ink, specifically formulated this way to cling to and transfer cleanly onto coarse paper which was designed to be rough so that it could absorb as much ink as possible. Compositors, which was the name for this particular vocation during the 19th century, would keep their letters in a type case with large letters at the top and small letters at the bottom. The letters were kept in what was effectively a suitcase which did not close which is where the terms “uppercase” and “lowercase” originated from, as the letters were stored in either the upper portion of the type case or the lower portion of the type case. Each individual letter, a block referred to as a “sort”, was cast in metal and crafted backward to be arranged by hand by a skilled craftsperson. The layout of the case, with capital letters in the upper section and lowercase letters in the bottom, was highly pragmatic, as it positioned the most often used letters at the bottom closer to the person setting the typeset. Interestingly, this pragmatism influenced the English language as compositors not only set letters, they also selected when to use punctuation, spacing, and line breaks, all of which shaped how text was read and understood. Because movable type requires physical pieces for every character used, punctuation was to be used deliberately as too many commas, colons, em dashes etc. meant more time spent, more metal used, and more space being taken up upon the page. This physical constraint helped standardize English punctuation use and even influenced sentence structure, encouraging clarity and economy in writing which are themes that have endured into the 21st century

The Fallacy of the American Cowboy Dueling at High Noon

Leave a comment

The classic cowboy motif of two gritty outlaws squaring off at high noon in the middle of the street is a fallacy. Street duels directly related to the American West have only occurred 5x – 10x from 1860 – 1900. The most well renowned high noon dual and the inspiration for much of the cowboy genre aesthetic within Hollywood cinema was in 1865, a standoff between Bill Hickok and Davis Tutt in Springfield, United States of America. This particular dual inspired over a century of cinematic exaggeration and hyperbole within the film genre. In reality, most gunfights within the American West during the 19th century were spontaneous, chaotic, and rarely honorable (e.g. ambushes from behind saloon doors or shootouts from areas with ample coverage etc.). Whilst Hollywood would later romanticize these rare dual encounters, the cowboy lifestyle day to day was far more rugged and utilitarian than it is depicted within media. Cowboys were working class laborers, much like agricultural workers of the modern day, they were often young, diverse in background, and driven by necessity of survival rather than personal glory. These men and women spent long days upon horseback herding cattle across a vast and unforgiving landscape, contending with harsh weather cycles, animal stampedes, and the constant threat of injury via animal or human being. The cowboy period of American history, although brief, played a vital role in shaping the economic and cultural landscape of the American frontier

The Advent and Evolution of Noodles Within China

Leave a comment

The oldest known noodles ever discovered were found in China and date back 4000 years, discovered virtually fully preserved in a sealed bowl buried beneath sediment. These noodles were not made of wheat but rather from millet, which provides insight into early culinary traditions of the ancient world. These millet based noodles were distinct from future varieties which relied upon wheat, reflecting the grains available in ancient China during the period. This discovery demonstrates the early noodle making techniques which became refined over the coming centuries. By 400 B.C., noodles existed across Asia, likely produced by mixing flour and water into a dough. In comparison to the noodles from 400 B.C., which were likely produced using wheat or other grains and kneaded into dough, the 4000 year old noodles appeared to have been hand pulled and stretched into thin strands rather than being cut. By 400 B.C., more structured noodle cutting methods had emerged, allowing for different regional styles and preparations of noodles to develop (e.g. Lamian which is a hand pulled noodle still popular during the modern day, Dao Xiao Mian which is shaved directly from a block of dough, Biang Biang Mian which is known for its wide belt like shape etc.). These discoveries highlight not only the ingenuity of early civilizations but also the evolution of food production and technologies to produce said food. The shift from millet based noodles to flour based dough reflects advancements in milling, agricultural practices, and culinary techniques, demonstrating how food has continuously adapted over time to the resources available to local populations

The Architecture Which is Most Resilient to Earthquakes

Leave a comment

During the Chilean earthquake of 2010, very short buildings (e.g. 3+ stories) and very tall buildings (e.g. 25+ stories) were virtually unaffected, with the bulk of damage pertaining to buildings which were 10 – 20 stories high. The reason why shorter and taller buildings are able to withstand earthquakes with greater chances of survival is because earthquakes have natural rhythms which are frequencies. Crustal earthquakes have a high frequency like choppy water, and thus shorter and taller buildings are not affected. Subduction earthquakes move much slower in their rhythm and frequency with approximately 1 swell/cycle per 1 second, which causes sizeable damage to mid sized buildings. 10 – 20 story buildings tend to vibrate at 1 swell/cycle per second which causes a dangerous synchronicity in the vibrato as the rocking becomes more intense in its amplification with each additional second or swell/cycle, until the earthquake stops or the building collapses. Taller buildings sway much slower which gives them a lot of built in protection against even the largest earthquakes found throughout history
