The Advent of the Steam Engine Permanently Changing the World

Scottish mechanical engineer James Watt taught himself engineering and at age 27 he invented the modern steam engine. Watt was inspired by a pot of tea which he observed boiling, as the lid of the kettle would move when excessive heat had built up. Watt realized from this encounter that steam power may have the ability to be harnessed to perform work. Building upon a design already in existence which used steam to drive a piston to pump water out of mining operations, Watt revolutionized this technology by adding gears and wheels. Early steam engines only pumped up and down, but after Watt discovered how to effectively implement wheels and other facets, he took the idea of steam power and made it transportable via rotary motion. This simple alternate design paved the way for countless machines which succeeded it, as gears and wheels allow an infinite number of combinations to be constructed allowing for adaptations to all forms of industry. The world became smaller and faster seemingly overnight as humans and animals were no longer required to perform all forms of work. Watts’ engine started the Industrial Revolution, one of the most important periods within human history as it nearly autonomously created the modern technological age

The Correlation Between Cats and the Bubonic Plague of Europe

During the Middle Ages and up until the Salem Witch Trials, cats were killed alongside their owners who were believed to be practicing the dark arts of magic, sorcery, and witchcraft. Typically cats were burned alive in ceremonial bonfires. Ironically, had this not occurred, the Bubonic Plague probably wouldn’t have been as prolific as it was as the fleas found upon the rats who carried the disease, would have been killed alongside their host by the very cats which were killed in droves by human beings. Cats are partially resistant to the Bubonic Plague but with few to keep the rat population in check, the plague was able to wash over Europe and kill 25,000,000 (25 million) people which was 25% of the European population

How U.S. Teacher Amos Bronson Alcott Influenced the Educatuonal System of the Modern Day During the 19th Century

Amos Bronson Alcott, a man once described as the most intelligent person of his era, developed the concept of recess for students as well as the concept of raising ones hand in class. Alcott believed in desegregated classes, mixing both Caucasian and African American students during the 19th century. Alcott fulfilled his dream of opening an adult educational institution in 1879 which he entitled “The Concord School of Philosophy and Literature” in Orchid House which was the Alcott family home in Concord, United States of America

The Argument Against Private Corporation Umbilical Cord Blood Storage

Canadian Blood and Tissue Bank Insception Life Blood claims that 80 life threatening diseases (e.g. various cancers, metabolic diseases, immune diseases etc.) can be treated with umbilical cord blood, and that these diseases have been treated with success for over 2 decades, with over 45,000 pediatric transfusions worldwide. The majority of these transfusions however were accomplished due to public cord blood banks. Physicians can tap into worldwide public registries with nearly 1,000,000 (1 million) donors to find a match for a patient and this service is free. In the setting of leukemia or a genetic defect, physicians would want to use cord blood which is not biologically related to the patient to avoid having the problem continue. The American Academy of Pediatrics states, “private storage of cord blood as biological insurance should be discouraged”. There is a caveat to this however, in the case of a child having a genetic defect, it is recommended that the family save the cord blood of the next child, if another child is born. It is believed that private cord blood corporations leverage fear, uncertainty, and timed pressure to cajole families into deciding to privately store cord blood. Insception Life Blood has stored cord blood from 70,000 infants yet only 14 were released for transplant, a value of 1 in 5000

Inventions and Discoveries Developed Simultaneously Throughout History

In 1922, a pair of Columbia University sociologists named William Ogburn and Dorothy Thomas published a paper entitled “Are Inventions Inevitable?” which stated that Ogburn and Thomas discovered 148 examples of documented simultaneous invention. This phenomena occurred in 1876, when Alexander Graham Bell and Elisha Gray filed for a patent for the telephone on the same day with Bell’s unit having a separated listening and talking piece whilst Gray’s unit having a single listening and talking unit built into a conical structure. Other notable examples include Charles Darwin and Alfred Russel Wallace who came up with the Theory of Evolution simultaneously, Carl Scheele and Joseph Priestly who discovered oxygen at the same time, Isaac Newton and Gottfried Leibniz who discovered and developed calculus at the same time, Dmitri Mendeleev and Alexandre-Émile Béguyer de Chancourtois who discovered and developed the periodic table at the same time, and Orville and Wilbur Wright and Samuel Langley who invented the airplane during the same period of time. Knowing this, it would seem that the phenomena of simultaneous invention and discovery seems to be exceedingly common for human beings throughout history

Scientists Who Studied the Sun by Looking Directly at it

Thomas Harriot observed sunspots in 1610 but did not publish his work. In 1612 Harriot recorded that after having viewed the sun, his sight was “dim for an hour”. Oxford University astronomer John Greaves is quoted as stating that after sun observations, he would see afterimages which looked like a flock of crows within his field of vision. Sir Isaac Newton attempted to look at the sun in a mirror, which blinded him for 3 days and caused him to experience afterimages for months

The Educational and Social Benefit of Children Playing Videogames

Children who play videogames for 3+ hours per day have better memory and better impulse control than those who do not play videogames

Bakers and Grocers Using Additives to Increase Profit Margins During the Victorian Period

Profit margins were incredibly thin for Victorian bakers so to stretch flour as far as possible, they would add all sorts of additives to adulterate the end product (e.g. clay, plaster of Paris, sawdust, chalk, and alum, the same chemical used to clean swimming pools during the modern day etc.). Alum had both bulking qualities and acted as a bleach for the flour, so alum despite it being the most dangerous additive, was also the most popular supplement during this period. Victorian grocers would use tactics like watering down milk to stretch it as far as possible, going even further than bakers when it came to food tampering. Grocers would often add red lead to cheeses like Red Gloucester cheese, add iron sulfate to pickles to make them appear more green, spruce up old vinegar by adding sulphuric acid, add poisonous Prussian blue to tea leaves, and mixed mercury with children’s candy to enhance its color

The Industries Disrupted by U.S. Entrepreneur Steve Jobs and U.S. Inventor Thomas Edison

Steve Jobs affected and subsequently disrupted the computer industry, the motion picture industry, the music industry, and the telecommunucations industry, all within a single lifespan. This achievement places Jobs at the status of a world renowned icon, a person like Thomas Edison who affected all of the same industries as well, swapping only the computer industry for the electric industry. Edison invented the incandescent light bulb for the electric industry, the phonograph for the music industry, and the motion picture camera for the film industry, and improved the telegraph and telephone for the telecommunications industry. Jobs developed the Macintosh computer for the computer industry, the animation studio Pixar for the film industry, the iPod and iTunes for the music industry, and the iPhone for the telecommunications industry
