The Length contraction is also called as Lorentz-Fitz Gerald contraction or space contraction in relativity physical science. It is the marvel wherein the shortening of an object along the direction of its motion comparative with an observer happens. Measurements in any other different ways are not contracted. It is normally just visible for an extensive portion of the speed of light. Comparative with the moving article if a spectator is very still, would notice the moving object to be contracted along its length. For example, an object when moving at relativistic speed relative to the observer would have a measured length which is less than 100 feet and the same object at rest might be of 100 feet long. The item is really contracted long as seen from the fixed reference frame. The measure of compression of the article is reliant upon the item's speed comparative with the eyewitness/observer/ measurer. This length contraction marvel was proposed by George FitzGerald and Hendrik A...

  What is Li-Fi?            Li Fi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light emitting diodes (LEDs) to transmit data.  In 2011, professor Harald Haas made a Li Fi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC) VLC uses light as medium to deliver high-speed communication in a manner similar to Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional and fully networked wireless communication technology based standard similar to Wi-Fi’s IEEE 802.11. How does Li Fi work? LiFi is high speed, bidirectional, and fully networked wireless communication of data using light. LiFi consists of several lightbulbs that form a wireless network. When an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. LED bulbs are sem...

  1. Smart Home Smart Home is inarguable the most popular IoT application. It is an application that allows the user to access the home appliances like lighting, heating, security, and entertainment remotely. It provides security, comfort, and convenience to the owners. Netflix and YouTube have become the necessities of today. We all have Smart TVs that connect to the internet and allow us to browse various applications. 2. Wearable Smartwatches are the most common wearable tools right now. One of the first IoT inventions, Bluetooth, was initially used to exchange messages between devices. Today, IoT wearable can display calls, text messages, social media updates, and track fitness and health. We are not just talking about Fitbits, but also devices like pacemakers and insulin pumps that can connect to the IoT for added monitoring. 3. Smart City A few examples of smart city solutions using IoT include smart parking, waste and water management, and smart lighting. A city's Smart Park...

3D printing, also known as additive manufacturing, is a technique for layering a three-dimensional object using a computer-generated design. Subtractive manufacturing procedures, in which a final design is cut from a larger block of material, are the polar opposite of additive manufacturing. As a result, there is less waste from 3D printing. 3D printing is also suitable for rapid prototyping. Thermoplastics, such as acrylonitrile butadiene styrene (ABS), metals (including powders), resins, and ceramics are among the materials used in 3D printing. Hideo Kodama of the Nagoya Municipal Industrial Research Institute invented the first 3D printing manufacturing equipment when he invented two additive processes for generating 3D models. Hideo Kodama's early work in Laser Cured Resin Rapid Prototyping was finished in 1981, building on Ralf Baker's work in the 1920s for creating decorative objects (patent US423647A). With the launch of stereolithography in 1984, his innovation was...

What is Environmental Engineering ?           Environmental Engineering is one of the branches of Civil Engineering. It aims to protect the constituents of the environment . An environmental engineer tries to improve the atmosphere . They work to improve soil, water, air quality and thus protect human health.           The stream “Environmental Engineering” isn’t a new concept. It has been practised since the beginning of civilisation . Ancient people also dealt with the challenges of the environment!!! You might be wondering, but yes, they had created different methods to treat solid waste and sewage. The Industrial revolution has caused depletion in air quality. Thus, people started to worry about air and soil pollution. So by this, we can understand the need for environmental engineering. They help in developing methods to clean the environment.           G.D Agarwal (1932-2018) is on...
