Civilizations Mastery of Metal By Manipulating Fire

The more carbon rich a fuel is, the more heat it produces. Typical wood fires burn at 700 degrees Celsius, however 6000 years ago, ancient people discovered the adaptation of burning wood in a low oxygen environment, only partially burning, but in doing so creating a much purer carbon rich fuel; charcoal. Charcoal can burn at temperatures upwards of 1100 degrees Celsius, hot enough to melt ore out of rock. The mastering of metal produced tools, finance, and weaponry, forever changing the evolutionary story of human beings. By the Middle Ages, the production of charcoal for metal smelting and metal work was a major industry


The First U.S. Presidential Vaccine Mandate

U.S. President George Washington issued the first presidential vaccine mandate, requiring all soldiers within the continental army to become vaccinated against smallpox on February 5, 1777. 90% of deaths during the American Revolution were due to disease, with smallpox being the most prevalent and difficult pathogen for the military to control. Immunization was viewed as an achievable solution to a virtually insurmountable problem as death from smallpox plunged from 30% to 2% after a becomming immunized. Vaccination, or “variolation” as it was referred to during the era, was achieved by taking a small piece of an active smallpox sore from an infected person, and then introducing it to the person being inoculated via inhalation or by scratching their arm and introducing the virus by touch. The mandate, although initially detested, became highly successful in its pursuit of lowering soldier mortality rate, with 40,000 soldiers vaccinated by the end of 1777

The Rationale as to Why Scientific Fact is Often Referred to as “Scientific Theory”

The term “theory” placed behind suffixes of large theories like gravity, evolution, and special relativity (e.g. the Theory of Gravity, the Theory of Evolution, the Theory of Special Relativity etc.), doesn’t mean “theory” in the traditional sense. During the 20th century, Sir Isaac Newton’s Laws of Motion began to break down within the theories own borderlines as physics progressed further and further to answer continually larger and more complex questions. As a direct result of this, a grander, more encapsulating law was required to explain certain phenomena (e.g. the reason the sun has a corona of light bend around it during a total solar eclipse) which is why Albert Einstein’s Theory of Relativity is so immensely important, as it explains such phenomena after which Newton’s laws begin to break down (e.g. Newton’s ability to predict planetary orbit but not explain why such a function occurs in nature etc.). Eventually the international scientific community unanimously agreed that laws should not be named as such because they may not remain laws in the long term, as there may be concepts outside of them which help explain both the supposed law itself as well broader phenomena outside of the suppositional law. The term “theory” was utilized to replace the term “law” because something scientific which can change over time, is not or was not truly a law to begin with. The term “theory” is used in the connotation of an idea which accurately describes a phenomena and empowers an observer to accurately predict what they have yet to observe. An idea isn’t genuinely a “theory” until it’s supported by empirical evidence, before which time it remains as a “hypothesis”

The Reason Alcoholic Hangovers are Unpleasant

A hangover at its most basic premise is caused when the body does not have enough water to run its citric acid cycle (also referred to as “CAC”, “tricarboxylic acid cycle”, “TCA cycle”, and/or “Krebs cycle”). This is exactly the process which occurs when a person dies of thirst. Although hangovers are typically not dangerous, this is part of the reason why they feel so uncomfortable
