Rockets are traditionally not re-used unlike aviation aircraft because making a landing from space means that a craft must come back to Earth’s atmosphere at a speed of 8 kilometers per second, a much more difficult task than that of landing a commercial aircraft at a cruising speed of just over 800’ per second
The city of Jingdezhen, China had for centuries been the ceramic capital of China, but it was the manufacturing of porcelain which gave China it’s first world recognized brand, built off of the back of the Ming vase. If the emperor requested a piece of pottery from Jingdezhen, 10 identical pieces would be manufactured, with only 2 being sent to the emperor. The remaining 8 pieces could not be touched by human hands and subsequently were destroyed in the imperial kiln
The Chinese developed moveable type around 1040 A.D. during the Northern Song Dynasty by the inventor Bi Sheng. Moveable type were essentially dies which were inked and pressed onto parchment of some kind (e.g. silk or paper). This invention was developed a full 400 years before Johan Gutenberg invented the printing press
The underground cave site of Derinkuyu, Turkey, commonly referred to as “Cappadocia”, is an underground network of caves and tunnels which date back to the prehistoric era, as evidence of stone tools have been uncovered at the site. Experts believe that 20,000 – 60,000 people inhabited the Cappadocian caves with indication of air vents and water wells making it theoretically possible to live underground for extended periods of time, spanning years even. Stone wheels made of volcanic basalt were fashioned to create what’s referred to as “self sealing doors”. The rocks would be rolled in front of a pathway making entry impossible for invaders due to the inability to gain leverage. The only possibility of entry would be to cut through this wheel, often up to 1’ thick in width, which would waste valuable time giving those upon the other side time to prepare a counter attack
During 2014, 40,000,000 (40 million) people visited Las Vegas, United States of America and lost a combined total of $10,000,000,000 ($10 billion). The average odds of winning when using a slot machine are approximately 6.6% meaning that for every $100.00 put in, the casino takes $6.60, baiting players with a win but bleeding them dry in the long term, banking nearly $0.07 (7 cents) for every $1.00 dropped into them. Casinos with the worst odds are clustered within the Las Vegas Strip, and casino games with the worst odds are clustered within the middle of each casino itself. This snowman pattern of 3 grids, each one sitting on top of a larger one beneath, surrounded by a larger perimeter of less high function activities going on also occurs in other industries including the design of digital circuits, agricultural design for industrial farms, indigenous villages layout and design in Africa, and occurs naturally within the biology of the human body. These systems are designed for maximum efficiency
The person who is accredited with creating the term “renaissance” is Giorgio Vasari. Vasari published a book entitled “Le Vite de’ più eccellenti pittori, scultori, e architettori” which means “The Lives of the Most Excellent Painters, Sculptors, and Architects” in Italian. The book is often shortened in its title and called “The Lives of Artists”. This book has over the centuries become the most influential art book of all time. Within the preface of the book, Vasari uses the term “rinascita” which means “rebirth” in Italian, to describe what was going on around him. Vasari stated that under the ancient Greeks and ancient Roman’s, art and civilization reached it’s highest levels of perfection, and that when the barbarians which are modern day Germans, arrived in Italy, the arts as a whole fell to ruins. The Renaissance is considered to have occurred between 1400 A.D. – 1600, with the beginning and end dates being slightly vague on each end
As of 2012, there are an estimated 6,000,000 (6 million) Freemasons worldwide. It is believed by some experts that the Freemason fraternity was established during the building of Solomon’s Temple, which occurred in 1000 B.C.. The original universal symbol of the Freemason society has a geometric compass at the top, letter “G” in the middle, and a squared ruler at the bottom. The compass is considered the main tool of the Freemason and stands for the perfect circle it draws in which a Freemason can stand. It is believed by the Freemasons that when having gone outside of this circle, a Freemason will find trouble and lose control. The only way to enlarge the circle is to seek knowledge. The square is iconography designed to represent wisdom and virtue. The letter “G” represents the “grand architect of the universe” but also can be interpreted as God or geometry, as it is believed by some experts that God is a grand architect and that geometry, specifically sacred geometry is the language of the universe. The goal of the Freemason organization is to promote free thinking, as it is believed that doing so is the only way to inoculate oneself from any tyrannical person or organization set out to enslave civilization
The USS Thresher was the first ever U.S. submarine to sink to the seafloor. It’s hypothesized by some military experts that the infamous John Walker who was acting as a mole within the U.S. Navy, tipped off the Russians as to the location of the USS Thresher and that the submarine was attacked in revenge for a Soviet submarine entitled “K-129” which was lost 10 weeks prior to the USS Thresher event. The Russians believed that a U.S. Navy Destroyer ship ran over and through the Russian submarine K-129 despite the U.S. Navy claiming no involvement whatsoever. The forensic evidence points towards implosion due to a leak of some kind, most likely near the seals of the propeller or the trash shoot, making it impossible for the USS Thresher to rise to the surface or be saved by a nearby vessel
After hitting an iceberg during its maiden voyage, the Titanic stayed afloat for less than 3 hours. Rivets used in the manufacturing process which were also used for many of the United States’ modern megastructures, were fit using a technique in which the rivet is heated and then hammered through a hole subsequently cooling and contracting, which pulled together the pieces of anything it was attached to. As the rivets of the Titanic popped out after impact, it allowed for a zipper like opening of the ship which conceded water to flush inward. Modern ships do not use rivets for this very reason and instead opt for welded hulls. It is impossible to build a ship which can withstand either an iceberg or a rock edifice with both being found below the surface of the ocean quite frequently. The only resolution is to use Radio Detection and Ranging or Radio Direction And Ranging (RADAR) and a global positioning system to steer clear of these hazards. Modern oil tankers have double hulls which reach right upside the entire ship but modern commercial ships normally do not bring their doubled hulls this high as it is an expensive safety feature which is bypassed as commercial ships do not carry oil which is financially and environmentally costly when spilled, alongside the fact that double hulled ships take up valuable space which could otherwise be used for cargo transportation. Instead commercial and industrial ships invest resources into safety systems better equipped for the needs of the people and/or goods which they transport
Tesla vehicles use approximately 8000 small cell batteries close to the size of a double A (AA) battery, only slightly larger with a length of 65 millimeters and a width of 18 millimeters. Tesla originally used this battery size because of its wide abundance but will be switching to a slightly larger size with a length of 70 millimeters and a width of 21 millimeters when their gigafactory is complete. Tesla claims that these new batteries will be the best and cheapest option in the world. Competitor manufacturers use different kinds of batteries than Tesla because of their belief in how the technology works and how efficient it can be
