Air hockey is a fun, mindless activity for everyone to play but do you really know the complex science behind it? Air hockey involves concepts from Newton’s three laws of motion. The science behind air hockey is all based off of Newton’s laws. The air hockey table allows the puck to glide easily and certain forces are required to move the puck, stop the puck, and accelerate the puck. Also, for every force applied on the puck, there is always an equal and opposite reaction. The next few…

For example, Asimov has no idea when it comes to fixing his automobile. Asimov’s auto mechanic fixed his car every time it was not running properly. Although the auto mechanic could not score well on an academic exam, he was intelligent in his own trade. Asimov states that “in a world where I could not use my academic training and my verbal talents…

Short-Term Financial Goals Preparing the personal financial plan, personal financial goals, and balance sheet and income statements felt like a daunting task. Primarily because finances were something that I always thought about, but I did not want to know the “real” truth regarding my financial health. The second principle of personal finance, “Nothing Happens Without a Plan” fits well in my situation because I persistently avoided viewing the entire picture when it came to our family’s…

The T-41 (i.e., the military version of the Cessna 172) had a "simple mechanical" flight control system using direct mechanical linkages. Direct feedback of forces acting on the control surfaces to the control stick (or yoke) provided a natural feel. The feedback was by the "seat of the pants". The trim system was a mechanical linkage connected directly to a trim control wheel in the cockpit. There is no warning in the T-41 if the trim was set incorrectly. It is the pilot’s responsibility…

Did you know parachutes come in all kinds of different shapes? The shapes vary from circles to triangles. However which one is the fastest? There are many factors that effect the speed of parachutes. Kinetic and potential, for example, influence the parachutes speed and movement. When a skydiver jumps out of an airplane gravity pulls him towards the ground and he doesn’t have enough air resistance to safety land on the ground. That’s where the parachute comes in! When the skydiver pulls the…

(U) The actual full utilization of aerial reconnaissance using heavier than air platforms occurred during World War I. The use of this new technology aided field commanders, and gave strategic planners unprecedented insights into enemy dispositions, capabilities and extrapolated battlefield intentions. The British employment of aerial reconnaissance was mainly tactical during World War I and was used to map out the battlefield by cartographically plotting out the Forward Edge of the Battlefield…

engine was precisely manufactured with no moving parts making it low maintenance. Each TIE Fighter pilot was equipped with a fully sealed flight suit superior to their rebel enemies. For added weight reduction, the fighters are designed with no landing gear but instead structurally capable of sitting on its wings. The cockpit incorporates a crash webbing, a repulsorlift antigravity field, and a high-g shock seat to help protect the pilot during crashes. TIE fighters…

The United States of America is notorious for being a land where opportunities abound and dreams come true. It is common to hear stories of great Americans who ascended from the clutches of poverty and amassed great wealth, because they had a dream and pursued it. They did not allow their circumstances, no matter how daunting, to overshadow their ambitions of success. Richard Ira Bong is a perfect example of such an American. He was simply a farm boy with a deep longing to fly airplanes. He…

Ornithopter The Human-Power Ornithopter, a wing-flapping device, was designed in 1485 with the intent to fly. However, there is no evidence that he attempted to build the machine, but his ideas of human powered flight device followed for the next several hundred years. His inspiration came from birds or bats, which lead to the two-wing device feature. The wingspan exceeded 33 feet and the frame consisted of pine covered in raw silk, which is light but sturdy. The pilot, laying down in the…

By being a "good" inventor you have to design, plan, test, and make your invention perfect. Some scientists ultimately fail, but Orville and Wilbur Wright definitely didn't- they invented the first motor aircraft that we still use almost 100 years later! They were obviously good scientists! When the Wright brothers were building and testing their new airplane, they had people helping them throughout the process. At a time when the Wright brother's propeller shafts, the part of the airplane…
