The First Advancement of Medieval Gunpowder Technology

Medieval-gunpowderTo 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 Usage of 5D Crystals as a Means of Computational Storage

5D-Superman-Memory-Crystal

Quartz is being used to create the most powerful data storage device ever developed, the 5D Superman Memory Crystal, a technology which could store data for up to 13,800,000,000 (13.8 billion) years, the calculated age of the universe. The 5D quartz crystal is a method of ensuring a large density of data can be saved within a relatively small object. This is an incredibly secure and long lasting method of saving data as the information is physically encoded into the crystal itself, remaining indefinitely until the quartz itself is destroyed, a very difficult task in and of itself. In 2018, technology entrepreneur Nova Spivack used a 5D crystal to create a permanent space library, sending it to the International Space Station aboard the SpaceX Heavy Falcon rocket. Quartz is highly stable because it is a crystal, remaining unchanged for billions of years meaning if data is inserted, theoretically it could survive for billions of years. For a quartz crystal approximately 2.5 centimeters by 2.5 centimeters in diameter and 5 millimeters thick, 30 terabytes of data can be held, which is 30,000 gigabytes or 800 Blu-ray discs or 600 smartphones worth of information. This means that the entire British library could be fit into 1000 5D crystal slides, a small enough volume to fit within a single shoebox. A traditional storage medium like a compact disc, stores data in individual pixels, with 1 pixel able to hold the equivalent of 1 bit or 8 bytes of information. In a quartz drive however, each voxel can hold 8 bits or 64 bytes of information. The technology required to achieve this feat however is still in its infancy with scientists still discovering new ways to refine manufacturing, the writing and reading of data, and storage capabilities

The Comparison of Medieval Gunpowder Explosives toward Modern Day Plastic Explosives

plastic-explosiveDuring 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

Ancient Roman Emperor Julius Caesar’s Contribution to Time Keeping

Julius-CaesarThe month of July is a derivation of the name, “Julius Caesar”. The ancient Romans opted to rename “Quintilis”, the original name for July which means “fifth month” in Latin, to “July” after Caesars death because this was the same month that he was born. The Julian calendar, a western calendar used until 1582 when the Gregorian calendar supplanted it, is also attributed to Caesar as the Roman year had only 355 days and required an extra month be added, every 3 years. The ancient Romans repeatedly made the same calculation errors and continually found seasons out of synchronization with the actual calendar date observed. With the help of a few Roman scientists, Caesar removed the pre-Etruscan 10 month solar calendar in favor of the 365 day year calendar named after himself. The Roman calendar started on March 25, but was moved to January 1 with the advent of the Gregorian calendar

The Invention of Star Luminosity Mapping to Measure Immense Distances in Space

Henrietta-LeavittHenrietta Leavitt, a brilliant scientist who worked at the Harvard Observatory discovered the true size of the universe because of her ability to objectively measure the true brightness of stars. Leavitt became enamored and fascinated by a type of star referred to as a “cepheid variable” which means a “star which pulses within the night sky”. Leavitt’s revolutionary breakthrough occurred when she realized that the intensity of brightness is precisely linked to how quick or slow at which the star blinks. If 2 points of light blink at the same rate but with different intensities, it would stand to reason that the brighter star is closer to the observer than the dimmer one. This allowed Leavitts to measure the distance to stars which lay far beyond the reaches of parallax distance

The Future Technology of Carbon Nanotubes

carbon-nano-tubeThe atomic structure of carbon, more specifically naturally occurring diamond, is neatly stacked in a cuboid shape. Carbon nanotubes use carbon but instead stack their atoms in a hexagonal shape. The result is a material which weighs virtually nothing, yet is stronger than any material known upon Earth, including poly-paraphenylene terephthalamide, more commonly referred to as “Kevlar”, zylon, and titanium. Some scientists have argued that carbon nanotubes will most likely be the strongest substance in the known universe and that nothing will ever have the ability to surpass its strength. Carbon nanotubes have a strength of 200 gigapascals; to provide frame of reference, the strongest materials known to civilization have a strength of approximately 5 gigapascals. 1 gigapascal, which is commonly abbreviated as “GPa”, is equal to 1,000,000,000 (1 billion) pascals, and 1 pascal, which is commonly abbreviated as “Pa”, is the SI unit for pressure defined as “1 newton per 1 square meter”. If a space elevator ribbon made of carbon nanotubes stretching 100 kilometers were ever to break (e.g. the counterweight above breaking), it would gently float down to Earth because it would only weighs 7 kilograms per every 1 kilometre of length

Galileo Galilei’s Telescope Design Improvement upon the Dutch Spyglass Design

Galileo-Galilei-telescopeIt had been known since the first spectacles were produced in the middle of the 13th century, that glass was capable of bending light, a property which no other known material of the period could achieve. The Dutch spyglass worked upon this very principal, arranging lenses with careful attention to detail to create a compounding magnification effect. If light hits a plano-convex (pronounced “play-noh”) lens, which is flat upon one side and convex upon the other, the same formation used for those who suffer from hyperopia, rays of light streaming inward are bent toward eachother, eventually meeting and converging at a specific triangular point. Right before this focal point, Galilei improved the original Dutch design by placing his second lens, an ocular lens which is plano-concave, meaning flat upon one side and concave upon the other, the same formation used for those who suffer from myopia. This secondary lens pushes the bent rays of converging light back out again so that they can hit the eye and provide a clear image. The eye focuses this light upon the retina so that the observer can view the image produced by the spyglass. The magnification power of a telescope depends upon the ratio between the focal lengths of the lenses, with these distances marked as F1 for the distance between the front of the spyglass and the plano-concave lens, and F2 from the plano-concave lens toward the back of the spyglass. The largest difficulty impeding Galilei was the grinding down process of his convex lens, in an attempt to make it as shallow as possible to maximize the length of the F1 partition, as the longer the distance is, the greater the magnification will be. Within a few weeks of developing this new technology, Galilei’s first telescope had a clear magnification of 8x, far exceeding the power of the original Dutch spyglass. On August 21, 1609, Galilei climbed a Venice bell tower to meet up with Venetian nobles and senators so that he could display his new technology. This new bleeding edge feat of engineering permitted Venetians to spot sailing ships 2 hours earlier than if they had used the naked eye. 3 days after the event, Galilei gifted his telescope to the Duke of Venice and was afforded a guaranteed job for life in exchange, with this salary equating to double his original income. With his finances secured, Galilei went on to develop and produce even more powerful telescopes

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

Konstantin-TsiolkovskyRobert 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 First Industrial Revolution, Second Industrial Revolution, and Impending Third Industrial Revolution

Third-Industrial-RevolutionIndustrial 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
