Modern airplanes are truly engineering marvels. They overcome high turbulence and unpredictable currents in the air and undertaking many complex maneuvers to complete their flights. Have you ever thought of how the pilots are able to do this? Or what happens to the aircraft when the pilot operates plane controls? In this article, we will explore how an airplane flies, and how pilots are able to control an airplane in a logical yet simple way.  First, let's have a closer look at modern aircraft's wings and tails. One amazing thing you will notice is that they are not made as a single body. The wings and tails of the aircraft contains many movable parts. The most fascinating thing about the whole wing, and the different parts of it, is that they form a very special shape in fluid mechanics. That is the airfoil shape. Just by understanding the physics behind this simple shape will allow you to completely understand airplane physics.  Let's learn more about airfoils. An airfoil...

    Planet Earth is the home of every life-form, known to us, in the universe. Its age is about 1/3 of the age of the universe and, admitted, it is a thing of beauty. A slightly squashed fair with a heavy metal core,   and a lighter surface crust, wrapped in a thin sliver of sweet air to breathe, with vast oceans, fertile plains,   magnificent mountains,   fresh water rivers, streams, lakes and aquifers, orbiting a star which warms us, and gives us energy. But how did our home come in to existence, and what's it made of? 4.6 billion years ago, Earth was created from the remnants of dead stars that collected in a giant, dirty gas cloud. The gas cloud became denser in its center, and formed an accretion disk. Small particles started clumping together, and building larger and larger objects; until they form the objects we call "Planets" today. This process took 10 to 20 million years, and is still not very well understood. At about this time, when the solar syst...

The fifth generation of wireless technology has made it to cities in the United States. Across the country,T-Mobile, Sprint, and others are laying the foundation fora faster, better internet, but in the race to develop 5G, U.S. firms are already at a disadvantage. They have limited access to some of the radio frequencies that enable 5G, and operators worry that there's not enough space to meet anticipated demand.  In Chicago, Verizon download speeds reached a maximum above one gigabyte per second. While maximums are interesting, median speeds say more about coverage. Look in South Korea, and you'll see higher median speeds. That means their networks maybe faster in more scenarios. To understand why the U.S. has a disadvantage, you've got to understand how wireless technology, like 5G, works. Most wireless systems rely on radio waves that can carry signals back and forth between your device and a service provider. To run these systems, firms like Sprint or Vodafone have to b...

Electric cars or internal combustion engine cars: Which is better? Electric cars were in their heyday back in 1900. But a sudden rise in petrol engine cars, accompanied by battery technology inefficiencies killed electric cars by 1920. However, with recent improvements in battery technology and power electronics, electric cars have made a strong comeback. We will compare these totally different technologies scientifically, and come to understand which is superior.  An IC engine is the prime mover in petrol cars. The fuel supplied to the engine produces combustion and enough pressure and temperature energy to move the pistons. The linear motion of the piston is transferred to rotary motion using a slider crank mechanism. A transmission is used to transfer this rotation to the drive wheels. In an electric car the power source is from a battery pack. An inverter converts the DC battery power into three-phase AC. The three-phase AC can turn an induction motor, which will thus turn the ...

We are living in a simulation or at least that’s what the simulation hypothesis proposes. That if a civilization, a post human civilization, were to become significantly technologically advanced than we would most likely is a simulated. There are two worlds, two realities. The primary world which is where the simulations being run and the secondary world, the simulated universe we occupy which to us is the only one. And when creating this world, there are three steps to successfully making the user believe it to be real: Immersion, Absorption, and Saturation.  Think about video games like Age of Empires, Civilization, and The Sims. They’re about recreating or mimicking reality reliving past events or creating new ones. And in 20 years we went from games looking like this to this. As visuals advance, as the experiences become more immersive and digital characters start reacting seemingly on their own, our understanding of what is real and what isn’t a start to blur. Now characters i...

In 2024, SpaceX aims to send the first humans on a 6 month trip to Mars. This journey will be the very beginning of Elon Musk’s goal to make life a multi planetary species. In order to achieve this, SpaceX will need to establish the first Martian base and - over time - the first Martian city. Using their Star ship rocket, thousands of people will be able to travel to Mars and lay the foundation for the first human civilization outside of Earth. But how will the first astronauts establish a base on Mars? And what laws will they follow?  In this blog, we’re going to look at what it will take to build a self-sustaining city on Mars. We also going to look at how Martians will form their own laws in order to grow the first settlements into thriving cities. When the first astronauts arrive on Mars they will need a place to stay. Since the Martian surface is exposed to much more radiation than Earth, the first Martian habitats will most likely be built underground. More sophisticated habi...
