Ever since the Homo Sapiens have gained undestanding, they have been taking inspiration from the Nature in all of their creations and Aircrafts are one of those creations too. In their attampt to fly like the birds, Humans created the Aircrafts . During the development stage of the aircrafts, there was one problem coming constantly in the way i.e., the lift. The aircraft needed to rise before it could take any flight and after the years of trials and researches, the answer was found in the form of "AirFoils" or "AeroFoils". AirFoil is basically the shape of a wing, blade or sail which produces an aerodynamic force providing aircrafts enough lift to rise. There are two components of forces produced when an Airfoil is moved through a fluid. The component perpndicular to the direction of motion is called the "lift" while the parallel component is known as the "drag". The magnitude of these components depend upon the angle of attack and its orien...

The only common thing between a road car and a formula 1 car is the wheels and the steering wheel. Except that each and everything is different. Even though lots of technologies from F1 car are adapted to road cars, F1 cars are impossible to match. The basic formula for F1 car is simple though. 1:- Lightweight 2:- Lots of power. And the most critical factor that sets f1 cars apart is…. 3:- Aerodynamics Combining these three ingredients in right proportions a workshop will bake you a perfect f1 car. Weight:- The minimum weight of f1 car with empty fuel tank is around 650kgs. The same of road car is around 1500kgs. Engine:- F1 car uses standard v8 engine. It has about 780 Hp for better performance and better toque. While a roadster use 1.4-1.8 ltr. Engine having 90-130 Hp. Gearbox:- F1 car uses 7 speed semi controlled electrical gearbox while a roadster has 5 speed manual or automatic gear box. But a F1 gearbox lasts only 1500 kms. while the gearbox of a street car l...

What do we know of the current state of research in material science? Not so much, but some of the most interesting discoveries or innovations are being made to make some of the lightest and strongest materials. Today we are going to talk about some of them. We all want things to get lighter and stronger simultaneously but it is not so easy but some very important materials are discovered just for the above reasons. Some of the most promising innovations are discussed below. The first material we want to talk about is Micro-Lattice Materials. It is a synthetic porous metallic material consisting of an ultra-light metal foam. Its density is as low as 0.9 mg/ which makes it one of the lightest material known to science. It was developed by a team of scientists from California-based HRL Laboratories, in collaboration with researchers at University of California, Irvine and Caltech, and was first announced in November 2011. The prototype samples were made from a nickel-phosphorus all...

The scientist from Washington state university, Prof. Yi Gu, invented in the field of thermoelectric, the use of converted heat to generate alternative forms of energy.           The device is multicomponent, multilayered composite material called “van der Waals Schottky Diode”. This device converts heat into electricity upto three times more efficient than silicon.           In 1820 Thomas Johann Seebeck discovered that temperature difference between two dissimilar electrical conductor or semiconductor are in contact produce electromotive force or voltage, this is because change in temperature causes electron to jump from hot side to cold side and form current. This effect is called SEEBECK EFFECT.           In electronics world, Schottky diodes are used to guide electricity in a specific direction, similar to how a valve in a water main...

“It’s a never ending battle of making your cars better and also trying to be better yourself” A supercar is a luxury, high-performance sports car.  The term is used in marketing by automakers for unusual and expensive vehicles, and has been used to refer to different sorts of cars: Limited-production specials from a specific autobuilder. Simple looking cars modified as per the requirements of the user for unbelievable power and performance Models from smaller manufacturers that appeal to enthusiasts One-of-a-kind "showcase" project vehicles built by custom car retrofitters (usually extensively modified collectible muscle cars or grand tourers updated to the latest "streetable" racing technology). An advertisement for a high-performance car similar to the Bentley Speed Six, appeared in The Times for 11 November 1920 with the phrase "If you are interested in a supercar, you cannot afford to ignore the claims of this supercar”. The Oxford English Dicti...

Last time we talked about Time Crystals which are a form of perpetual motion machines. So what exactly are perpetual motion machines and why do we keep searching and learning about them? Perpetual motion machines are machines which basically do not follow the laws of thermodynamics and can do work without requiring any energy. It sounds impossible right?  But some of the greatest scientists have given much of their time in producing such a machine as it would lead to a world where we do not need any energy source but can get unlimited energy. The concept of a perpetual machine is believed to have taken seed from the renowned mathematician Bhaskara’s views about perpetual motion. He sketched a wheel with curved reservoirs in which Mercury was filled in equal proportions and allowed to flow. Now the reason behind it was that as the mercury would flow and as the wheel would start rotating, it would never stop as the mercury will flow downwards in subsequent reservoirs a...

Since the inception of  humankind, we have been finding a way to achieve everything for free and a huge amount of time and resources had been invested to gain the energy without any cost. In this world of Science and Technology, we have been able to discover a lot many matters and crystal structures having symmetry across space but recently, scientists and researchers have discovered a crystal having symmetry not only across the space but across time too. They have named it as “Time Crystal” .  Don’t get fooled by thinking that time crystal to be a time travelling crystal but this state of matter has got some awesome kind of properties. Generally all the matter are motion less at its resting state and only possess kinetic energy when some short of energy is applied to it. As for example a cricket ball remains in steady state unless and until the bowler throws the ball. But the interesting thing about the time crystal is that they keep moving even in their ground state or...
