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
