The Advent of the Imaginary Number Concept

Leave a comment

The value of “i” which represents an imaginary number is quite useful for balancing seemingly impossible tasks like when resolving problems with electricity or wireless technologies. Working with wave functions involves working with the value of an imaginary number because of its ability to resolve mathematical problems. If numbers are thought of as a straight horizontal line on an X axis, with 0 in the middle, with all negative numbers on the left hand side of zero (e.g. -1, -2, -3 etc.) and all positive numbers on the right hand side of zero (e.g. 1, 2, 3, etc.), then imaginary numbers would be plotted upon the Y coordinate axis, displayed vertically (e.g. +1i, +2i, +3i going up or -1i, -2i, -3i going down etc.). This allows imaginary numbers to be treated the same as regular numbers, just upon a different plane of axis. Imaginary numbers are essential to certain tasks like aircraft radio tower control as imaginary numbers allow for technologies like Radio Detection And Ranging (RADAR)

The Tragic and Untimely Sinking of the Titanic

Leave a comment

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

How Stealth Aircraft Technology Works

Leave a comment

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

Italian Astronomer Galileo Galilei Determining the Speed of Light

Leave a comment

The speed of light was once thought to be infinite and able to travel over infinite distances instantaneously. The polymath Galileo Galilei thought this to be incorrect and had an assistant stand atop a hill 1 kilometer away whilst Galilei shone a lantern and had the assistant shine one back as soon as he recognized the opposing lantern being lit. Galilei posited that he could measure the reaction time and divide it by the distance between both parties. The experiment failed to work because a much greater distance would be required for success. During the 1670’s, the Danish astronomer Ole Roemer closely observed Jupiter and its moon Io. Roemer noticed that his predictions of where Io should be did not synchronize with its actual position and subsequently realized that because Jupiter and Earth are sometimes closer together, the travel time of light between each could take between 1 hour and 1 hour and 15 minutes. Due to this realization, Roemer was able to calculate that light coming from Jupiter’s moon Io traveled at approximately 300,000 meters per second. Today scientists can verify Roemer’s experiment by pulsing a laser beam towards mirrors left upon the moon by astronauts during the Apollo missions the National Aeronautics and Space Administration launched in decades past to confirm that the speed of light is indeed 299,792,458 meters per second. The lasers scientists use act upon the same principal Radio Detection and Ranging or Radio Direction And Ranging (RADAR), Sound Navigation and Ranging (SONAR), and Light Detection and Ranging or Laser Imaging Detection and Ranging (LIDAR) utilizes in that they all measure objects at a distance by pinging them to approximate how fast they are traveling, and how far away they are
