The Period When Classical Artwork Transitioned From 2 Dimensions (2D) to 3 Dimensions (3D)

Leave a comment

Art broke away from being two dimensional caricatures with the invention of the camera obscura which had the painter sit in a dark room, with the window blocked out with a small hole in it. Doing so would cause the image outside the window to be projected into the room of the painter and onto the canvas, which could then be traced. The image, as with cameras and the human brain is brought in upside down, so the painter would be forced to trace upside down. During the Tudor period, lenses were developed for the first time which allowed artists to learn to paint with realism because after tracing and creating the minute details of each face correctly, they could focus on light and shadow. The camera obscura acted as a starting point to stencil a face. Boards were put down the back of the person sitting so that they would sit perfectly still allowing the painter to sketch them in perfect render. This technology acted effectively the first camera and in that, the first glimmer of Renaissance artwork

The Origin of the Birthday Celebration

Leave a comment

The origin of the birthday celebration tradition within China dates back thousands of years. The Chinese marked birthdays, starting from the first year of survival, as a mark of how long one has survived with the hope of longevity ahead. Besides matching the year with one’s own astrological calendar (based upon 12 years rather than 12 months), the Chinese traditionally celebrated during antiquity and continue to celebrate birthdays during the modern day with noodles, specifically chang shou mian which means “long life noodles” in Mandarin. This is because it is believed within Chinese culture that long noodle strands consumed within a single attempt symbolically represent a long life to come. It should be noted, it is believed the foundation origin of the concept of the “birthday” originated within Ancient Egypt around 3000 B.C. with Ancient Egyptian pharaohs celebrating their own coronation day as a birth of a god, with the Chinese, and later the Germans, developing the concept of a birthday more reminiscent to the modern day

The First Person to Theorize How Stars are Situated Within the Universe

1 Comment

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

The Artificial Black Hole Created by U.S. Scientists

1 Comment

In Menlo Park, United States of America, in May of 2017, scientists working at the Stanford Linear Accelerator Center National Accelerator Laboratory (often abbreviated as “SLAC”) fired the world’s most powerful X-ray laser at individual molecules. The reason for this experiment was to observe what would occur when an atom with a lot of electrons is hit by high energy X-ray radiation to observe whether or not those electrons could be knocked out of orbit producing an atom which instead of having many electrons has very few electrons. This system behaved highly unusual and very differently than what scientists expected as it created a miniature black hole like object for 1/1,000,000,000,000,000 (1 quadrillionth) of a second, sucking all remaining electrons into it and exploding the molecule in a dramatic paroxysm

The Reason Icebergs Sink Ships

1 Comment

The reason that an iceberg is able to cut into the side hull of a ship (e.g. Titanic etc.) or any other marine vessel is dual fold. The first reason is because steel becomes more brittle, the colder it gets. Steel created during the early 20th century was not tempered as steel is during the modern day. The second reason is because of inertia, weight, and force. An iceberg can slash through steel the same way a tree can rip through a vehicle that has hit it. An iceberg is a large, immovable object, so whether the hull is comprised of wood or titanium, the ice will always win out as it has more inertia and mass. To provide a frame of reference, bone is incredibly strong and tensile, however if a brick which is harmless while at rest, slams down from a height above the arm, the force it imparts is enough to break said bone

How Ocean Wind Turbines Produce Electrical Energy

2 Comments

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 Fallacy of Transgender Female Athletes Competing at the Same Biological Level as Cisgender Female Athletes

2 Comments

It is a common misconception that transgender athletes who transition from male to female have the same sexual dimorphisms and therefore the same athletic capabilities and baseline statistics as cisgendered women when competing within athletic competition. Cisgender males on average have 40% more upper body muscle/strength than cisgendered women and 30% more lower body muscle/strength than cisgendered women, although these are mere approximations which span the entire world population which is why this is not always the case. Female hormones can reduce these advantages by 5% – 10% within the human body of elite athletes, but it is at the current time, as of 2023, impossible to completely reverse the advantage of biological male puberty for transgender male to female athletes. Surprisingly, hormone therapy rapidly reduces hemoglobin levels to that of cisgender women however all other baseline statistics remain relatively the same post transition when using hormone replacement therapy. Even after 36 months of treatment, virtually all other baseline levels are higher than the average cisgender female. These discoveries suggest that physical strength may be preserved in transgender women during the first 3 years of hormone replacement therapy. It should be noted, if the athlete does not go through male puberty, these male hormone induced advantages do not apply. This is because these traits are largely associated with testosterone but not entirely

American Theoretical Physicist Robert Oppenheimer’s Reaction to the First Successful Nuclear Weapon Detonation

2 Comments

After the Trinity nuclear launch test which occurred on July 16, 1945, the first nuclear detonation in human history, when Manhattan Project lead Julius Robert Oppenheimer was asked about the reaction of himself and others on that fateful day Oppenheimer responded, “we knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture the Bhagavad Gita. Vishnu is trying to persuade the prince that he should do his duty and to impress him takes on his multiarmed form and says, Now, I am become Death, the destroyer of worlds. I suppose we all thought that one way or another” (this phrasing/sentence structure while confusing in English, is the correct direct translation from Sanskrit)
