The Origin of Polka Music

Polka arrived in Vienna, Austria in the 1840’s, imported from Hungary. It is believed Polka was invented by Anna Slezak, a peasant girl who invented the dance while entertaining herself by hopping around on a Spring Sunday afternoon. The term “polka” is derived from the Czech term “pulka” which means “half-step”, in reference to the dances main choreography pattern of lightly stepping from one foot unto the other

The Discovery of the Route Which Allowed Explorers to First Climb Mount Everest

British born George Mallory, the person tasked with heading the team who first set out to climb Mount Everest in 1921, overlooked what is now used as the doorway to Mount Everest, the entry point of East Rongbuk Glacier. When Mallory first viewed this entry point, a narrow cliff within the mountainside wall, he dismissed it as too modest and small to warrant further investigation. Canadian Oliver Wheeler however was educated in the science of topography and geography from his father who surveyed the Canadian west coast Rocky Mountains and because of this, he did not view the dimensions of the cut to be as important as the pulse of water pouring out of that cut every afternoon. This enormous volume of expelled water signaled to Wheeler that a glacier had to be present at the head of the valley as it was the only possible explanation which fit. On July 30, 1921, Wheeler set out for the East Rongbuk Glacier and as he anticipated, he was able to make it up the ice field within 6 short days. As the East Rongbuk Glacier widened and curved around, it came directly to the base of the North Col, a sharp edged pass carved by glaciers in the ridge connecting Mount Everest and Changtse (pronounced “chang-see”). This opening became the key to unlocking Mount Everest and is still leveraged by climbers into the modern day. 6 days after setting out, on August 4, 1921, Wheeler sent a dak runner, which is essentially a Tibetan messenger, with a sketched map indicating his discovered exploit of the armor of Mount Everest for Mallory

The Reason Aritifical Intelligence Differs From Traditional Software

Recently, many of the improvements made within the artificial intelligence sector have been due to the technology of “deep learning” which is also referred to as an “artificial neural network”. Traditional software is not intuitive as it simply follows a set of instructions predetermined by a programmer. If the software runs into a new problem which it has no answer prewritten for, it crashes. Deep learning is different as software can now write its own instructions instead of reading the instruction(s) of a programmer. Currently, as of 2021, deep learning is the equivalent of an all powerful, dim witted genie as it has the ability to evaluate the pixels of a photograph of a bottle of water, and can recognize with astonishing accuracy photographs of other water bottles, however it has no idea what the concept of water or the water bottle itself is, what the end user does to drink from the water bottle, what the end user needs the water for etc. This differs in human beings however as humans learn from a sample size of one, and are able to surmise the purpose of water and everything else which is relevant from witnessing it being used upon a single occasion

The First Advancement of Medieval Gunpowder Technology

To create the earliest form of gunpowder, 3 substances were mixed together which included, sulphur, charcoal, and saltpeter which is comprised potassium nitrate. Because these ingredients have varying specific densities, they constantly separated when mixed, forcing soldiers to re-mix gunpowder after having been transported to the battlefield. By the end of the 15th century, a new technique for the manufacturing of gunpowder emerged, that of corning which made gunpowder much more reliable. Corning involves mixing together the 3 primary ingredients to create a slurry. This is more effective than the traditional method because as the mixture dries, the ingredients do not separate due to their different specific gravities. This acts to increase the stability of gunpowder and allowed cannons to evolve into lethal siege engines no longer governed by the strength of soldiers or the laws of mechanics. Gunpowder, the first chemical explosive ever invented, was the driving force behind the weaponry used against fortifications, hurling projectiles faster, further, and with greater force than previously designed mechanically powered machinery (e.g. trebuchet, catapult, ballista etc.)

The Harvard University Hope Experiment

During the 1950’s, Dr. Curt Richter from Harvard University performed a series of experiments using water, buckets, and both domesticated and wild rats which resulted in a surprising discovery within the field of psychology. In the first experiment, Richter placed his test subjects into large buckets half filled with water with even those rats which were considered above average swimmers, giving up and dying within a few short minutes. In the second experiment, Richter pulled each rat out just as it was about to give up due to exhaustion and let them rest for a few moments. Upon inserting the rats back into the bucket of water, Richter found that the rats continued to struggle to survive for up to 60 hours as the rats now believed that if they continued to push forward with enough effort put forth, eventually they would be rescued once again. Richter recorded in his notes, “after elimination of hopelessness, the rats do not die”

The Comparison of Medieval Gunpowder Explosives toward Modern Day Plastic Explosives

During the modern day, soldiers use plastic explosives to blast through walls, similar to that of the gunpowder powered cannons of antiquity, but different in the sense that they can be directly applied and finely controlled. Despite these differences, the principle of both weaponry remains the same which is to create a powerful burst of kinetic energy to smash apart solid structures. Soldiers with explosive expertise during the modern day plant explosives in a lowercase “i” or “t” shape format by separating the explosives with a gap in the middle. This design ensures the explosive will blow a hole in the top and the bottom of the blast site, as well as the sides in some instances, leveraging the physics of the shockwaves produced to disrupt the wall and weaken it in the middle. Explosive experts don’t attach plastic explosives at the bottom of walls for two distinct reasons, the first being because the foundation upon the other side of the wall which cannot be viewed has the potential to be higher than the foundation facing the impending soldiers, which means that the explosives would be blasting into solid ground soil which is much less effective than blasting into walls made of concrete or otherwise, and the second being that explosives close to the ground create rubble directly next to the hole created, making forced entry more difficult, especially under siege conditions with active enemy combatants attempting to stop the breach. The main difference between Medieval gunpowder and modern day plastic explosive is the amount of material required to produce the same effect as plastic explosives are an entire order of magnitude more powerful than gunpowder, with 2 kilograms of plastic explosive equating to multiple barrels of gunpowder. Explosives are categorized as either “high explosives” or “low explosives” with high explosives having the front of the chemical reaction travel faster than the speed of sound and low explosives having the front of the chemical reaction produced travel slower than the speed of sound. To provide comparison, modern day C4 plastic explosives have a detonation velocity of 8,092 meters per second whilst gunpowder has a detonation velocity of just 171 – 631 meters per second

The Mathematics Behind Why Rockets Can Escape The Gravitational Pull of the Earth

Robert Goddard’s liquid rocket never reached the 3 kilometer mark because of Tsiolkovsky’s Rocket Equation named after Soviet scientist Konstantin Tsiolkovsky (pronounced “con-stan-tyin tsel-kov-skee”). This equation states that as fuel increases for faster and further voyages, so too does the weight, becoming increasingly heavy as more and more fuel is added. Tsiolkovsky took into account the velocity of a rocket alongside its mass of payload, mass of fuel, and the mass of the rocket itself. The longer the engine burns, the more velocity the rocket will have, however longer burning means more fuel which adds weight and makes it more difficult to push upwards. To travel fast enough to deliver a rocket to space, most of the craft must be fuel. Scientists have battled with this question for decades and although mathematical constructs have been developed to explain the relationship between weight and thrust, no one has yet to develop an idea to get around this problem with currently available technologies. The equation developed to explain this limitation of space travel is △V^R = V^E x log^e (M^P + M^F + M^R / M^P + M^R). This effectively states that only a tiny portion of a rocket can be used to deliver payload, with notable cases being the Apollo missions which employed enormous rockets to carry just a few small astronauts and the things they needed into space. Tsiolkovsky theorized this in the beginning of the 20th century as his calculations demonstrated that kerosine wouldn’t be enough to go from the Earth to the moon with a single craft

The Reason Carbonated Drinks Become Flat

Carbonated drinks are in a state of super saturation in respect to how much carbon dioxide they contain. Once a solution has reached complete saturation, it won’t allow any more of whatever substance is saturating it. If salt is added to a glass of water, eventually it will reach a point in which the salt just falls to the bottom rather than being dissolved in the water due to over saturation. If a solution is heated, it will be able to tolerate higher levels of saturation, and if it is cooled it is able to tolerate lesser levels of saturation. Carbonated drinks are water saturated with carbon dioxide, and this carbon dioxide is always looking for a method to escape which is why all carbonated drinks eventually turn flat provided enough time has passed. When sugar is added to a carbonated drink, the sugar nucleates the drink in that it provides a method of escape for the carbon dioxide present. Sugar, Mentos, and other various substances have a large surface area which allows a lot of carbon dioxide to become attached to it resulting in a rapid escape

The First Industrial Revolution, Second Industrial Revolution, and Impending Third Industrial Revolution

Industrial revolutions require 3 key components to occur, 3 defining technologies which emerge and converge to create the catalyst needed to usher in a new era of human achievement and progress. The first component is new methods of communication technologies to make communication more efficient and to manage economic and social life (e.g. video conferencing), the second is new sources of energy to more efficiently power economic and social life as well as governance (e.g. renewable energy technologies), and the third is new modes of mobility and logistics to more efficiently move economic and social life as well as governance (e.g. on demand ride sharing). The First Industrial Revolution was caused by the discovery of a new source of energy; coal. Coal powered the new communications medium, the steam powered press, and a new logistics structure via the locomotive railway. When these 3 technologies converged, much of the world (e.g. the whole of Europe) changed seemingly overnight. As a direct consequence of the First Industrial Revolution, business models moved toward market capitalism and major city hubs began developing ushering in the modern world format. The Second Industrial Revolution occurred in the U.S. during the late 19th and early 20th century with the advent of the telephone in the late 19th century, and the advent of radio and television in the early and mid 20th century. At approximately the same time that the telephone and telecommunications networks were being developed, the U.S found a new source of energy which was oil in Texas, United States of America. Henry Ford compounded this discovery by producing a cost effective combustion engine, powered by oil which provided new logistics and mobility technology. The Second Industrial Revolution however is now fading away due to the impact it has had upon the Earth’s climate and humanity is now upon the precipice of a Third Industrial Revolution. The internet has become the new communication medium, millions of people are now adopting renewable energy (e.g. solar, wind, geothermal etc.) and it is predicted that when autonomous vehicles connect to smart roads, the last piece of this puzzle will be complete, thrusting humanity into its 3rd epic epoch
