Speed: "In Depth"

     Speed has to do with how much energy you put into it and the resistance that acts against it whether that resistance is air or water. The concept as explained in the documentary is a paper plane. When one blows on the plane, the air underneath the plane is the one that lifts the plane up as it creates more pressure than the wind blowing on top of the curve. In terms of the sailboat, the wind actually drags sailboat forward. A traditional sailboat absorbs much of the wind resistance, rigid carbon fibre wings, on the other hand, deflect this wind resistance works pretty much the same way as the paper airplane. The airfoil beneath the sailboat allows water to flow faster through it than the rest of the boat which lifts the boat out of the water reducing resistance to energy. According to a research done on sprinters, every sprinter spends about the same time (0.3 seconds) to reposition the limbs. And though one may not notice, sprinters often push on the ground or hit the ground harder to maintain momentum. The greater the force, the faster one propels - a difference between professional sprinters and high school tryouts. Its the same as riding an exercise bicycle at home. One may not notice but after a few seconds leaning forward to accelerate and start the bike, one simply focuses on maintaining that momentum caused by putting pressure on the paddles with your foot. Similarly, on a bicycle one generates as much as 350 watts power to ride that bicycle. It is just as much as lighting up "7- 50 watts light bulbs". Though, this speed may be increased with the same amount of power if the bicycle were redesigned. In a "Recumbent bike", one travels as fast as 25%, as this bike has a "wind resistant" design.

    Speed is also a great factor in logistics. Package delivery routes for courier companies are often solved using algorithms and algorithmic software. Just like a GPS, courier dispatch often uses computer software that calculates the fastest route for as many as 100 locations in a matter of seconds. This saves couriers time and gas, not to mention the much slower depreciation of vehicles that pick up fewer miles and maintenance. Such algorithms may also be used in loading airplanes... Moving cargo is one thing, but moving information itself faster is another!  Stocks were originally bought and sold in person via a broker like an auction, but now the same auction happens within seconds in the comfort of one's home on their computer. High-frequency trading involves buying and selling stocks within seconds with large volumes. This high-frequency trading is another example where "Time is money in a very real way". Since even a thousandths of a second could mean a difference of millions of dollars in profit. Though one may think fibre optic is the fastest way for information data to travel, light in fibre optic travels 0.5 seconds slower than a microwave between microwave towers since light in fibre optic is slower than light in air.


    In conclusion, speed is an important currency in life. Designing products based on speed or using lighter material can play an important role in logistics and economy in general.

10 Most Expensive Typos Ever

       Whether it’s the programmer making an error in writing the code or an accountant making a blunder in a contract agreement, some Grammar mistakes cost companies millions, if not billions, of dollars. Letters that change the identity of an organization, punctuation marks that change the meaning of a sentence or even spelling typo that makes the reader ignore the main details of an essay ; all contribute to expensive blunders in history. Anyone can write a program code , but the ones that last are the ones that improve lives rather than make them miserable. Whether it's a missing keyboard key, a blurry computer screen or improper wrist orientation, an error is easy to make. After all, "to err is human". Unfortunately, the mistakes that cost millions are not very "forgiving" or "divine". Hence, " prevention is better than cure !" **  More Resources :  App: https://www.youtube.com/@numbrs3254 App Support Site: https://tekk-savvy.com B...

Driver Safety

        Dash Cam      Since the early 20th century, when the  automobiles were invented there have been millions of road accidents claiming millions of lives and millions of dollars from vehicle collision damage . Many of these accidents require the vehicles to be trashed in the junkyard for parts. Some accidents are lucky enough to have a minimum collision damage to vehicles that may be repaired and placed for resale in car showrooms. However, the prices of these vehicles  depreciate  even before the relisting of the vehicles. The buyer may also end up paying  high insurance premiums and maintenance based on make, model, mileage, and conditions of these vehicles. Manufacturers may be the least to blame for unfortunate circumstances that lead to most major accidents. There is no safety feature or material in the world that will stop metal and glass from penetrating the bare human body. Even Kevlar  vests  are only effectiv...
