Invention of the Telescope


Hans Lippershey was a Dutch/German tradesperson who fashioned eye glasses for a living. Lippershey created and designed the first telescope, and then patented it in 1608. The first telescopes could only magnify objects 3x closer than the naked eye. The telescope turned out to be one of the most important inventions of the 15th century because Galileo Galilei built upon the original design to create the field of astronomy which lead to groundbreaking new discoveries about the solar system and Earths place within the cosmos

Stealth Aircraft Technology


Stealth aircraft are shaped and angled as such so that any signal bounced off of them bounces in a direction different than that of how it came in making Radio Detection and Ranging or Radio Direction And Ranging (RADAR) unable to ping and receive a signal back which makes stealth aircraft essentially invisible as they cannot be seen with the naked eye due to the incredible speed and height at which they travel, nor can it be tracked with technology

The International Space Station


The International Space Station is approximately the size of a football field, orbits the Earth at over 28,000 kilometers per hour, and is situated 400 kilometers above sea level. The International Space Station is made up of 15 separate modules which come together and function as a single unit, with one end belonging to the United States of America and the other to Russia. Every piece of payload which is sent into space to be stored upon the International Space Station is weighed carefully, all the way down to the ounce

Engineering Pipes For Liquid Flow


The most efficient way to utilize gravity to carry water across long distances is to use a 4 degree slope. Doing so allows water to flow through the pipeline unimpeded whilst allowing a steady flow of air into the pipe so as not to create pressure upon the joints of any bends. Anything above 4 degrees will cause an area of turbulence referred to as a “hydraulic jolt”

Aircraft Carriers


Landing an aircraft on an aircraft carrier at sea is considered the most difficult task in aviation. The first aircraft ever landed on the deck of a steamship was accomplished in 1911, just a few short years after the Wright brothers had the first airplane become airborne. The task was accomplished by having ropes and sandbags run horizontally across the wooden landing stage on top of the deck of the ship. The rope caught a hook on the bottom of the landing aircraft and slowed it down, with each bag adding more and more weight. The engineering of this practice is still in use today, with the only significant difference being the components used, which are now high tension steel cables. Marines and navy officers jointly train for their wings, but navy officers are more likely to take off at sea, whilst marine officers are more likely to take off from land
