The Discovery of Pulsar Stars

Leave a comment

Neutron stars were thought to be preposterous when first suggested until 1967 when scientists used radio-antenna telescopes to map the universe. 3 pulses would be unusual, 4 pulses would be phenomenal, but scientists had received pulses from certain parts of the universe 24 hours per day, 7 days per week for months on end. The reason the pulses occurred was because every rotation of the neutron star causes energy to swipe past Earth exactly how light from a lighthouse sweeps light onto the oceans. Scientists first thought the pulses were from aliens until they proposed that the new star had to be denser than any type previously discovered, being the size of a planet but with the power of a star. Astronomers named these new stars “pulsars” and investigated continuously until 1 year later when they found a pulsar, burried deep within the remains of a super local, the pulsar known as the “Crab Pulsar” which is the closest pulsar to Earth. Interestingly, Swiss astronomer Fritz Zwicky had mathematically proven this phenomena 80 years prior but was labeled a hack for his wild theories

The Condition of the Earth After the Chicxulub Asteroid Collision Which Caused the Extinction of Dinosaurs

Leave a comment

Immediately after the Chicxulub Asteroid collided with the Earth, heat from the fireball produced reached temperatures of 5500 degrees Celsius and produced a shockwave which broke the speed of sound, causing gale force winds equivalent to a hurricane. Everything within 965 kilometers was instantly decimated. Within 11 minutes of impact, the sky began to darken as debris which had been pushed up into the atmosphere started to settle back down. As these small spheres the size of a grain of sand descended back down to Earth, they heated up upon re-entry, identical to that of an asteroid, which provided the illusion of billions of simultaneous shooting stars. The energy produced during this re-entry barrage of heat was more intense than the sun for a brief period of time and made the sky glow red, as if it was comprised of liquid magma. This debris reflected heat back towards the Earth and effectively caused the Earth to act as an enormous radiator. To add to this damage, wildfires began sprouting up due to the intense temperature which caused heat and smoke to fill the atmosphere, compounding the damage already done. Strong winds helped perpetuate these fires and because so much of the Earth was affected, it only took a few hours to become globalized, engulfing the entire Earth in a mass fire which burned hotter than a regular fire due to the inability to dissipate heat sideways. In addition to this, gypsum which contains sulphur, blocked the sun and cooled the Earth over the long term. Gypsum had a seismic effect upon the world’s oceanic ecosystems as ocean acidification occurred due to sulphuric rain being produced by the gypsum within the atmosphere. The reflecting of the sun caused 75% of all plants to die as the Earth only received as much light during mid day as what is present during a cloudy, moonless night of the modern day

How Flames Were Artificially Produced for Opera Productions During the 18th Century

Leave a comment

During the 18th century within opera and theater productions, stage doors which would lead a character to Hell achieved simulating the flames of Hell with brandy which would be placed into a container and lit on fire due to the fact that during the period, brandy was the brightest glowing flame available because of it’s high alcohol content. Once the brandy was burning bright, a powder referred to as “lycopodium” was blown across the flames to create an intense illumination, creating a fireball of sorts. It was in truth a very dangerous special effect to achieve because of the wooden sets, the actors involved, and the enclosure of the theatre itself. Most of those who performed the pyrotechnics for operas and plays during this period were ex-military, often soldiers who understood how these chemicals worked in depth as rocket technology was at the cutting edge of warfare during the era

The Advent of Oil Paint Storage Changing Artwork and the First Artist to Begin Painting Outdoors

Leave a comment

Tubed oil paint became available in 1841, superseding the traditional methods of storing paint in pigs bladders and glass syringes, which made traveling to a location and/or painting outside, suddenly possible, so that aspects of light and shadow would not have to be manufactured as with classical paintings, but rather they could be painted exactly as the artist laid witness to them. Claude Monet was the first Impressionist artist to start painting outdoors during the mid 19th century, often painting in the public’s view, outdoor scenery like The Manneporte which he painted in 1885

The Etymology of the Christian Demon Name “Lucifer”

Leave a comment

The name “Lucifer” in reference to Satan from the Christian faith is derived from the Latin terms, “lucem” and “ferri”, which mean “light” and “bearer”. Lucifer, and from that Satan, holds resemblance to Prometheus, a Greek god who is credited with creating the human race by spawning human beings from clay. Prometheus is also credited with providing civilization with the gift of fire, which resulted in him being punished when caught by having his liver eaten by an eagle by day and then growing back again at night, repeating this cycle ad infinitum

The Reason the True Age of the Universe Can Be Definitively Proven

Leave a comment

The discovery of the speed of light provided a satisfactory explanation as to why the world becomes dark at night. This is immensely important as the further a star is from an observer, the longer it will take for light to arrive from that point, to the observer themself. If the universe was infinite in its age, all of the light ever created would have had time to reach the Earth which would cause the night sky to be ablaze with starlight, photons emitted from every single possible part of the universe. This clearly is not the case so it is abundantly evident that the universe must have had an origin point. Scientists use the term “observable universe” as it’s entirely possible and likely that matter exists outside of what can be observed predicated upon the theory that as the universe expanded, light from this matter would have to travel increasingly larger distances to reach an observer. Because of constant expansion, this light has not yet had the chance to reach the Earth and perhaps never will, causing it to be outside of an observers field of vision and therefore unable to be proven in its existence using current methods and technologies

The Causation and Cure for Colorblindness

Leave a comment

Being colorblind is more difficult than most people believe as those affected often cannot match clothing colors, tell when fruit is ripe, tell when meat is cooked, or tell when traffic lights are various colors in certain lighting conditions (e.g. flashing red being mistaken for flashing yellow). Color vision is trichromatic with 3 types of cone cells within the eyes which consist of blue, green, and red, which are sensitive to short, medium, and long wavelengths of light, with each cone permitting an observer to view approximately 100 different shades. When all shades are combined, the human eye can observe approximately 1,000,000 (1 million) different colors. Colorblindness can stem from faulty cone cells or an interruption between the pathway of the cones and the brain. Colorblindness has caused vehicular deaths due to accidents around the world which have occurred most often because a driver perceived a light as yellow when it was red in reality. Neuroscientist Professor Jay Neitz (pronounced “nites”), a color researcher at the University of Washington in the U.S. and his spouse, geneticist Maureen Neitz, have teamed up to try and cure colorblindness. Gene therapy is currently being researched around the world and scientists believe that colorblindness will be cured using gene therapy in the near future. Male squirrel monkeys are naturally red-green colorblind and gene studies have demonstrated that these monkeys can be afforded color vision after having a gene delivered into the cone cells within the eye. The gene produced transforms a subset of the green cones within the male squirrel monkeys eyes to force them to become red cones, red cones which have hijacked the squirrel monkeys neural circuitry which was previously utilized solely for blue-yellow color vision, essentially bifurcating into red-green cones and blue-yellow cones so that the monkeys examined developed full color vision like human beings as of 2019. The Neitz’s confirmed this by providing male squirrel monkeys colorblind examinations which when answered correctly, delivered a small treat of food after having undergone gene therapy. Trials in human beings have yet to start as the Neitz’s believe that this step is still a few years away, but expected to initiate during the 2020’s

How Phosphorescence Works

Leave a comment

Glow in the dark products work because of a chemical additive which allows the product to absorb energy on one frequency, and reemit it as visible light which is a different frequency. Zinc sulphide and strontium aluminate are the most commonly used phosphors for photoluminescent products as they reemit energy over a considerably long period. When light is shone upon a glow in the dark object, incoming photons excite the phosphor molecules and these molecules then release that energy taken in by releasing photons and creating a dim light glow. Different phosphors release energy at different rates and thus, the slower a phosphor releases energy, the longer it will glow. The human eye is most sensitive to green light in the dark which is why night vision technology was traditionally created with a green tint

Ansel Adams’ Genius and Process

Leave a comment

The American photographer Ansel Adams pushed the mechanical process of photography into an art form during the 1920’s. Adams’ method was to work backward from the image he had visualized within his mind and then anticipate the moment when the light and subject could be seen at their most illuminating. During Adams’ day, color photography was considered crass, as color photography was thought not to contain nuance and the subtlety which matched the real world. Black and white photography allowed for a beautiful range of tonalities which was abstract but still considered to be realism artwork during the period. Today, with much more sophisticated technology and color materials, the world can be photographed accurately with many different nuances. Ironically, black and white now appears as an abstract artistic medium in comparison to full color photographs

Ancient Stained Glass Manufacturing

Leave a comment

The manufacturing of stained glass is an ancient technology which dates back so far that the ancient Egyptians knew how to do it 2000 years before the birth of Jesus Christ. Medieval Europe inherited this form of technology but did not invent it as is common belief. Deep, rich blue glass was very difficult to make and therefore needed to be imported from southern Italy. The deep blues which the Chartres Cathedral in Chartres, France is so famous for can historically be traced through documentation to fragments coming from the Byzantine Empire as well as the Roman Empire. These imports were melted down and used to create new glass. Most colors and dyes came from the natural world in the forms of roots, berries, barks, leaves, minerals, and crushed insects, but the most prized colors were imported into Europe from the east, specifically India and China using Ottoman trade routes. The simple luck of geography made Venice, Italy an incredibly wealthy city as it acted as a nexus between the east and west. The blue hue referred to as “ultramarine” was the most expensive color to acquire and therefore it was almost always saved for depictions of the Virgin Mary, typically in her cloak or some other form of clothing, as Mary was depicted as the focal point of every painting she appeared within. Ultra Marine came from the mineral of lapis lazuli and when it was ground up into powder, some parts would inevitably become smaller than others which allowed these particles to reflect more light and provide a deeper, richer color to work with and appreciate. Vermillion Red was almost as precious as ultramarine, and has been used in Europe for hundreds of years in various illuminated manuscripts. Made from the mineral cinnabar, vermillion was adopted in places outside of Europe like meso-America for painting, India for bindi dots, and China to create lacquerware
