Prior to the 16th century, it was believed that the Earth was the center of the universe with a belt of stars which rotated around it, exactly the same way in which planets orbit the central star of any solar system. These stars were believed to be fixed in their position as the constellations observed upon Earth do not alter greatly in their position or intensity in terms of what the human eye can perceive. Thomas Digges was the first person to propose that the stars are placed at different distances and in different positions, not in a ring of stars which stayed fixated, but rather in an infinite universe as distant points of light. Digges built upon the work of Nicolaus Copernicus by changing Copernicus’ original visual sketch of the planets and their orbital paths in that he removed the stellarum fixarum meaning “fixed stars” in Latin, and built a model in which stars were completely different in their distance relative to the Earth, with brightness controlled by how far or close a particular star was in proximity

How Ocean Wind Turbines Produce Electrical Energy
Wind turbines run upon a simple engineering principle which is that of wind causing the blades to turn which rotates a shift within the turbine, with this shaft producing energy for the electrical generator. This electrical energy is pumped downward, 300’ below the water surface, and into cables buried below the seabed which connect to offshore substations which then connect to onshore power stations and finally residential homes and industrial and commercial buildings. Ocean wind turbines are typically 600’ high in altitude, with spinning fiberglass blades which are approximately 240’ long, with each blade weighing up to 30 tonnes. Because of this immense size, measurements (e.g. angle of blades etc.) are crucial during the construction phase to maximize efficiency and energy output. A single revolution of a wind turbine can generate enough electricity to power an entire family home for 24 hours
The Mass Unidentified Aerial Phenomena Sighting in Nuremberg, Germany During the Renaissance
In 1561, a mass unidentified aerial phenomena sighting was documented above Nuremberg, Germany. Witnesses report observing a large black triangular object and spherical crafts falling from the sky, producing clouds of smoke. Hundreds of spheres, cylinders, and other various shaped crafts jostled erratically for 1 hour before departing. The event was described as a “battle”
The Parasol and the Advent and Evolution of the Umbrella
Parasols, the precursor to the umbrella, were initially comprised of tree leaves, specifically eucalyptus and palm branches. The original intent of the parasol was to stop ultraviolet radiation from the sun, from penetrating the skin and causing it to become tan. The term “parasol” is derived from the French term “para” which means “to shield from”, from the root Latin term “parare” (pronounced “pah-rah-ray”), and the French term “sol”, which means “sun”. Parasols and umbrellas can be separated by their appearance as parasols are typically colorful and lively whilst umbrellas are generally solid, muted colors (e.g. black, grey, white etc.). It was not until the 1750’s when English philanthropist Jonas Hanway began carrying an umbrella in public with the intent to avoid rain that the idea caught on as a social trend and a new technology. Umbrellas up until the 19th century were heavy, weighing approximately 10 lbs. as they were comprised of whale bone with wooden rods setup to support the canvas. In the 1920’s, Hans Haupt helped usher the next generation of umbrellas in by inventing the foldable umbrella, the same kind of umbrella used during the modern day
The First Person to Weigh the Atmosphere
Italian Jesuit Evangelista Torricelli was able to definitively prove that the atmosphere has a specific weight by designing an experiment in which a tube is filled with mercury and then placed into a dish of mercury. Torricelli disovered that when performing this experiment, half of the mercury runs down into the dish and the other half stays within the tubing. Until this point, it was believed impossible to create a negative or empty space as the Ancient Greek philosopher Aristotle once stated, “nature abhors a vacuum” believing that nature would forever fight against the creation of true and pure nothingness. This is the same reason that an object (e.g. plastic straw or an oil drum barrel etc.) crumbles when all of the air within is extracted. Torricelli was able to overcome this phenomena by using the exteme weight of mercury within a ridged glass tube. The level of mercury left within the tube was a measurement of the weight of the atmosphere, a balancing act between the weight of the mercury and the weight of air pressing down upon this mercury, balancing each other out like scales. Torricelli famously stated, “noi viviamo sommersi nel fondo d’un pelago d’aria” which means “we live submerged at the bottom of an ocean of air” in Italian, and his findings made scientists realize that air was a substance for the first time. Torricelli became the first person to invent the barometer because of his understanding of atmospheric pressure. Despite Aristotle being believed to be correct for millennia, Torricelli definitively proved that air does have weight
The Reason Scientists Can Calculate the Distance and Velocity of Galaxies and Stars
Scientists understand the immense distance between galaxies and stars because of American astronomer Edwin Hubble’s theory of the expanding universe, as it is now understood that galaxies drift from the observer proportional to their distance, meaning the further a star is, the faster it continues to move away from the observer. This phenomenon is referred to as “Hubble–Lemaître’s Law”. Astronomers can calculate how fast a star is moving away from the Earth by observing the Doppler shift of the light it projects, as yellow light becomes red light as a star moves away and yellow light becomes blue light as it approaches closer. A formulae is then used to calculate the distance from the source point. Redshift is observed throughout the universe which confirms that the universe is indeed expanding at a phenomenal rate of speed
The Canadian Government Forcing the Relocation of First Nations Persons to Expand Canadian Territory
During the 1950’s, the Canadian government sent a ship into Nunavik, Canada and forcibly confined 87 Inuit residents relocating these individuals much farther north into the territory of Resolute Bay, not for the benefit of the people affected as no one had ever lived this far north in Canada prior, with the sole objective being for the Canadian federal government to justify Canada’s sovereignty and territorial claim within the High Arctic. The Canadian government believed that if gravesites of Inuit persons were found in this region, it would formally and legally solidify the land as Canadian territory. Migration took 3 months by ship and when the Inuit arrived, they were provided no provisions, forcing them to setup tent shelters in the one of the most formidable and domineering landscapes of North America. The Canadian government fraudulently assured those affected that living conditions would be better with an abundance of animals to hunt and fish for despite few wild animals being present. This event was referred to as the High Arctic Relocation. The term for “Resolute Bay” within the In Inuktitut (pronounced “ee-nook-tee-tut”) language is “Qausuittuq” (pronounced “ko-so-ee-took”) which means “Place of Darkness” and/or “Place Where the Sun Does Not Rise”
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 Reason Aritifical Intelligence Differs From Traditional Software
Recently, many of the improvements made within the artificial intelligence sector have been due to the technology of “deep learning” which is also referred to as an “artificial neural network”. Traditional software is not intuitive as it simply follows a set of instructions predetermined by a programmer. If the software runs into a new problem which it has no answer prewritten for, it crashes. Deep learning is different as software can now write its own instructions instead of reading the instruction(s) of a programmer. Currently, as of 2021, deep learning is the equivalent of an all powerful, dim witted genie as it has the ability to evaluate the pixels of a photograph of a bottle of water, and can recognize with astonishing accuracy photographs of other water bottles, however it has no idea what the concept of water or the water bottle itself is, what the end user does to drink from the water bottle, what the end user needs the water for etc. This differs in human beings however as humans learn from a sample size of one, and are able to surmise the purpose of water and everything else which is relevant from witnessing it being used upon a single occasion
The Usage of 5D Crystals as a Means of Computational Storage
Quartz is being used to create the most powerful data storage device ever developed, the 5D Superman Memory Crystal, a technology which could store data for up to 13,800,000,000 (13.8 billion) years, the calculated age of the universe. The 5D quartz crystal is a method of ensuring a large density of data can be saved within a relatively small object. This is an incredibly secure and long lasting method of saving data as the information is physically encoded into the crystal itself, remaining indefinitely until the quartz itself is destroyed, a very difficult task in and of itself. In 2018, technology entrepreneur Nova Spivack used a 5D crystal to create a permanent space library, sending it to the International Space Station aboard the SpaceX Heavy Falcon rocket. Quartz is highly stable because it is a crystal, remaining unchanged for billions of years meaning if data is inserted, theoretically it could survive for billions of years. For a quartz crystal approximately 2.5 centimeters by 2.5 centimeters in diameter and 5 millimeters thick, 30 terabytes of data can be held, which is 30,000 gigabytes or 800 Blu-ray discs or 600 smartphones worth of information. This means that the entire British library could be fit into 1000 5D crystal slides, a small enough volume to fit within a single shoebox. A traditional storage medium like a compact disc, stores data in individual pixels, with 1 pixel able to hold the equivalent of 1 bit or 8 bytes of information. In a quartz drive however, each voxel can hold 8 bits or 64 bytes of information. The technology required to achieve this feat however is still in its infancy with scientists still discovering new ways to refine manufacturing, the writing and reading of data, and storage capabilities
