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 Tradition and Method of Selecting a New Pope

Vatican-SmokeMurder, bribery, and nepotism were the primary ways in which a pope would enter or exit the papacy prior to the 12th century. It was during the 12th century that cardinals who were senior clergy in Rome, Italy created what they referred to as a “college” to act as a council which would regulate the elections of future popes. This system became referred to as the “conclave” which refers to the practice of a “private meeting assembly of cardinals for the election of a pope”. The term “conclave” was chosen because of the Latin term “con” with means “with” and the Latin term “clavin” which means “key”, more literally translating to “locked room” as cardinals would be locked away to avoid the interference of outside politics. As of 1274 A.D., all papal elections are held in secret, adhering to this strict tradition in an attempt to remain unbiased. Elections are held again and again until a 66% majority is achieved at which point white smoke is released to signify that the council has reached a decision. The election ballets from each voting round are burned so that the election is completely anonymous and private, even for those who are present in the meeting. It is this burning which creates the iconography of the smoke being released to signify a decision. In the Middle Ages, cardinals added damp straw to the ballots which created black smoke to signify that a pope had not yet been chosen. White smoke was created by burning the paper alone, but during the modern day, chemical additives are added to ensure the white smoke color is as unambiguous as possible

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

The Test Subject and Scientific Experiment Which Proved the Fear Response in Human Beings Does Not Solely Reside Within the Amygdala

SM Amygdala MRIJustin Feinstein is one of the few scientists who have been able to study a woman who has zero fear response. To protect the woman’s identity, this subject is known only as “S.M.”, and Feinstein has had the opportunity to work with her under laboratory conditions and in real world scenarios (e.g. coffee meeting, sporting event, professional conference etc.) for the past 15 years as of 2018. S.M.’s lack of fear has had unexpected consequences within her life, as she displays no sense of typical fear induced scenarios (e.g. personal space, feeling completely comfortable being nose to nose with a complete stranger as the concept of personal space and discomfort has no meaning), heightened by the fact that S.M. does not produce typical signals of distrust when interacting with a novel person. S.M. lacks fear because she is without her amygdala, a physical trait observed in very few human beings, making S.M. one of the only people in the world to produce this physiology. S.M. has no amygdala because she has been diagnosed with Urbach-Wiethe Disease (pronounced “urr-bock vee-they”). The underlying etymology of Urbach-Wiethe Disease is still unknown but in patients with the condition, specific portions of the brain, in both hemispheres, can become subject to selective calcification which erodes the ability to function as designed. The amygdala acts as a sentry for potential fearful stimuli, and produces a response accordingly. The removal of or inability of the amygdala to work correctly results in a complete and total lack and/or loss of fear. This condition has caused S.M. considerable difficulty during her life as she has experienced dangerous interactions with those participating within the illicit drug trade. Upon one occasion, a stranger ran up to S.M., placed a firearm against her temple, and yelled “bang!”. Neighbors witnessed this event and notified law enforcement which puzzled S.M. as she did not view the event as dangerous or alarming and therefore did not expect to be contacted by the police. When the human body detects the intake of too much carbon dioxide, it can become pushed into a state of alarm. Feinstein wanted to better understand what would occur if he interfered with S.M.’s respiratory system, using 35% carbon dioxide during the first trial run. Feinstein found that S.M. was immediately fearful after a single intake breath, despite his original hypothesis of no fear response being observed. S.M. displayed an immediate and dramatic fear response with S.M. herself describing it as the “most intense fear ever felt” during her entire life. This single breath was revolutionary for neurology as it definitively proved that the amygdala is not the only region of the brain which controls and is related to fear

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

The Rationale Why Pharmaceutical Organizations are Not Incentivized to Develop Antibiotics and Why This is Dangerous for the Worlds Next Pandemic

antibiotic-resistanceWithin 5 short years of release, approximatly 20% of antibiotics become subject to resistance from bacterial pathogens which means that antibiotic proliferation is chronologically limited within its life expectancy. Coupled with this, if an antibiotic is highly effective, the scientific and medical community often rally against its usage so that such a tool can be saved in reserve for a global bacterial pandemic. In either scenario, return upon investment is less than what it would be with a different class of medication (e.g. selective serotonin re-uptake inhibitor, statin, hypnotic etc.) which is why pharmaceutical organizations are less interested in research and development dedicated to antibiotic medicine in favor of other, more profitable medication categories. This lack of investment however is myopic and will inevitably backfire upon the pharmaceutical industry as a whole if new antibiotics are not developed because medications used to treat cancer will become less in demand due to the fact that cancer patients are highly likely to acquire an infection during treatment when their immune system is comprised, with this infection often killing the patient if antibiotic solutions are not available. This would expectedly lead to a sharp decline in cancer medication treatment and subsequently pharmaceutical sales of related medications as patients would be likely to adopt living the rest of their life as fully as possible and forgoing treatment as they would be damned if they accept the cancer treatment and develop an infection which kills them but also damned if they don’t accept the treatment and let the cancer run its course which is almost always fatal

To provide comparison of the research, development, and manufacturing contrast between oncology medications and antibiotics, as of 2020, there are currently 800 medications in development for cancer and hypertension whilst only 28 antibiotic medications undergoing that same research phase and development process, with 2 of these antibiotics expected to become fully developed and able to reach the market and patients. The last new antibiotic class, lipopeptides, were introduced in 1984 with a gap referred to as an “antibiotic void” occurring during the 1990’s, 2000’s, 2010’s, and now moving into the 2020’s. The urgency of this threat is projected to become dire within the coming decades, with scientists predicting that by 2050, medicine could potentially come full circle to the pre-antibiotic era, with microbes which are completely and totally resistant to every antibiotic known to medicine

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 Reason Carbonated Drinks Become Flat

carbonated-soft-drinkCarbonated 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

European Neolithic Mining Practices

Neolithic-mineDuring the Neolithic period, flint was as prized as gold was to the Hindus, Christians, and Buddhists. 4500 years ago, flint miners dug shafts up to 12 meters deep in search of more flint. Ladders and wooden platforms made extracting the ore easier. This task was Herculean as the only picks available were reindeer antler. When a mine was exhausted, a new hole would be dug and the rubble from that hole would be used to back fill the previous mine. Most flint can be found above ground and most of the flint found at Neolithic sites is indeed surface flint so it is unclear why such a massive undertaking was performed as much more readily available sources were freely available. Flint is black in color with a shiny, glass like appearance similar to obsidian. Flint chips easily and is fairly simple to make incredibly sharp by simply cracking off a piece with a harder rock. It’s possible that mine shafts were dug as a ceremonial coming of age tradition in that a prepubescent adolescent would enter into the mine, dig into the depths of the Earth, and then emerge back out as an adult. This theory is backed up by the fact that the majority of miners left their picks in the mine, possibly signifying that they had reached adulthood. It is unclear if these picks were left because they were considered to be spiritually polluted or if they offered their pick as an offering to the Earth itself in exchange for what has been brought to the surface. There is a site in Britain at which over 400 of these mines were dug a few meters from eachother giving the landscape a cratered appearance

The Projected Impact of Trees Upon Climate Change

ForestThroughout history, it is estimated that human beings have cut down 2,000,000,000,000 (2 trillion) – 2,500,000,000,000 (2.5 trillion) trees. This means that even if human beings plant 1,000,000,000,000 (1 trillion) trees within the coming decade(s), this would only replace 40% – 50% of what has been taken from nature. Drones are now being used to plant trees, capable of planting 120 trees per minute per drone at 10% of the traditional cost to do so. If humanity were to plant 20,000,000,000 (20 billion) trees per year for 50 years, which is a sustainable rate, this still only equates to 1,000,000,000,000 (1 trillion) trees which once again would only replace 40% – 50% of that which has been taken. It would take 9000 drones operating 200 days per year to accomplish this feat. Drone production for this project would not require drones more complicated than a modern day smartphone. Trees, plants, grasses etc. are essentially crystallized air, and are more than 95% formed by air. This means that the mass of a tree is equitable to the mass of oxygen which it has been crystallized from, effectively adhering to the Law of the Conservation of Mass, the First Law of thermodynamics. The average tree weighs 2 tonnes with 50% of this weight being carbon, which means that 1,000,000,000,000 (1 trillion) trees is directly equitable to 1,000,000,000,000 (1 trillion) tonnes of carbon. The land requirement to produce such an ambitious project would take half the land mass of Brazil, with larger trees actually requiring less land, paradoxically
