How Holograms Work

Holograms work by taking a single laser beam and splitting it into 2 parts, with the primary beam falling upon the object being photographed which then bounces away and falls onto a specialized screen, and the secondary beam falling directly upon the screen. The mixing of these beams creates a complex interface pattern containing a three dimensional image of the original object which can be captured on specialized film. By flashing another laser beam through the screen, the image of the original object suddenly becomes holographic. The term “holograph” is derived from the ancient Greek terms ”holo” which means “whole” and “graphos” which means “written”. The main issue with holographic technology is that unlike traditional visual media which needs to flash a minimum of 30 frames per second, scattering the image into pixels, a three dimensional holograph must also flash 30 frames per second, but of every angle to create depth of field, and the amount of data required far exceeds that of a traditional television photograph or video, even exceeding the capability of the internet until recently in 2014 when internet speeds reached 1 gigabyte per second

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 Successful Flight Machine

Paper makers Jacques-Étienne Montgolfier (pronounced “jha-ack ee-tee-yen mon-go-fee-yay”) and his brother Joseph-Michel Montgolfier (pronounced “zho-seef mee-shell mon-go-fee-yay”) created the hot air balloon after noticing that paper in their factory would be lifted by warm currents of air. This discovery lead to the innovation of hot air being confined within a bag which birthed the modern hot air ballon, an overall design which has remained relatively unchanged since its advent in 1783 despite advances in technology. As hot air is filled into a sack, the sack becomes less dense than the air which surrounds it, allowing the sack to rise in its altitude, be it 1 meter or 10,000 meters. The first successful untethered flight with passengers occurred on September 19, 1783. This initial flight was completed by a sheep, duck, and rooster. The first flight with humans occurred just 2 months later, with the hot air balloon raising 3000’ into the air and traveled a distance of 8 kilometers. The Age of Flight was born during this event as it was the first time in human history that a person or group had successfully lifted off the ground and remained in control of their flight path trajectory

The Discovery of the Route Which Allowed Explorers to First Climb Mount Everest

British born George Mallory, the person tasked with heading the team who first set out to climb Mount Everest in 1921, overlooked what is now used as the doorway to Mount Everest, the entry point of East Rongbuk Glacier. When Mallory first viewed this entry point, a narrow cliff within the mountainside wall, he dismissed it as too modest and small to warrant further investigation. Canadian Oliver Wheeler however was educated in the science of topography and geography from his father who surveyed the Canadian west coast Rocky Mountains and because of this, he did not view the dimensions of the cut to be as important as the pulse of water pouring out of that cut every afternoon. This enormous volume of expelled water signaled to Wheeler that a glacier had to be present at the head of the valley as it was the only possible explanation which fit. On July 30, 1921, Wheeler set out for the East Rongbuk Glacier and as he anticipated, he was able to make it up the ice field within 6 short days. As the East Rongbuk Glacier widened and curved around, it came directly to the base of the North Col, a sharp edged pass carved by glaciers in the ridge connecting Mount Everest and Changtse (pronounced “chang-see”). This opening became the key to unlocking Mount Everest and is still leveraged by climbers into the modern day. 6 days after setting out, on August 4, 1921, Wheeler sent a dak runner, which is essentially a Tibetan messenger, with a sketched map indicating his discovered exploit of the armor of Mount Everest for Mallory

The Traditional Sherpa’s of Mount Everest

The term “sherpa” is derived from the terms “shyar” (pronounced “shur”) which means “east” and “pa” which means “people” in Nepali. Migrants who populated the region around Mount Everest throughout antiquity came from the Tiber in the east, crossing the Nangpa La, which means “Elder’s Pass” in Nepali, to settle into Solukhumbu (pronounced “solo-koom-boo”), a region in which the minimum altitude is 4000 meters above sea level. Living a nomadic lifestyle is what made the sherpas expertise so desirable to British mountaineers who arrived a few centuries later. British mountain climbers realized the immense value that these expert travelers possessed which is how the relationship of domestic sherpas and foreign alpinists began. Sherpas were and continue to serve as porters and guides for foreign climbers and during the modern day, a sherpa trekking Mount Everest can expect to earn $6000.00 upon an expedition which intends to reach the summit

The Tallest Mountain On Earth

Mauna Kea (pronounced “mah-nah kay-ah”) is the tallest mountain in the world, 1.6 kilometers taller than Mount Everest. The main difference between Mauna Kea and Mount Everest is that Mauna Kea ascends from the ocean, instead of from land as Mount Everest does. Mauna Kea is not only the largest mountain on Earth, it is also the largest land mass in the world

The Discovery of the Sunken S.S. Titanic

The S.S. Titanic’s shipwreck site was found by the U.S. Navy whilst embarking upon a clandestine military submarine sea voyage operation in 1982. The intent of the mission was to surpass the Russians on every front, including land, sea, air, and space. Geologist and Navy Captain Robert Ballard was the person who developed the mission idea by suggesting that the U.S. Navy scour the seafloor to gather intelligence and search for evidence of Soviet placed hardware. The original intention of the mission was to locate and recover 2 U.S. Navy submarines which were classified as top secret nuclear attack vessels and lost during the 1960’s. The first submarine was the U.S.S. Scorpion, lost in 1968 with 99 onboard, and the second was the U.S.S. Thresher, lost in 1963 with 129 onboard. Recovery of these vessels during the 1960’s was limited to the Sound Navigation and Ranging technology of the era, commonly abbreviated as “SONAR”. Ballard only had 12 days to locate the S.S. Titanic during the mission without exposing his cover story, a feat which was unable to be completed by the French and the Americans, despite having much longer time spans and multiple expeditions to achieve this goal. Ballard narrowed down the search area to 80 square kilometers and focused towards the south as he believed that ocean currents would have carried sunken debris in that direction. Ballard continued searching for a trail of scattered debris from the S.S. Titanic and on the 9th day of the expedition, with time quickly running out, the operators of the remotely operated vehicle ARGO, found wreckage from a modern iron ship which appeared to be from the early 20th century. It was confirmed shortly after on September 1, 1985 at 12:48 AM that these remains were 1 of the 29 boilers belonging to the S.S. Titanic. It had been 73 years since the S.S. Titanic was last seen, resting nearly 4 kilometers below sea level, with it’s 1500 onboard passengers and crew

European Neolithic Mining Practices

During 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

Throughout 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

The Advent of the Computer Mouse

The computer mouse became a mainstream accessory for computers shortly after Steve Jobs viewed a prototype mouse from Xerox in 1979. Jobs asked his team to create a mouse which was under $15.00, would last for 2 years, and could be used upon either a particle board desk or the jeans of a persons lap. Dean Hovey ended up creating the concept of the computer mouse by visiting a drug store after Jobs made this request in a business meeting. Hovey purchased a roll on deodorant and a butter dish and began working upon the initial design. Hovey popped the spherical applicator out of the deodorant and covered it with the butter dish to make a rollable, undulating handheld device
