Sensors

INTRODUCTION           Sensors are devices which are used to detect and respond to certain physical actions. They are able to respond to physical parameters like Temperature, Humidity, Touch, Radiation, Speed etc... They convert these parameters to electrical signals which can be measured through devices. It is not an independent device and is always used with other devices. Just like Humans they can sense their environment and respond quickly. They are better than humans when it comes to sensitivity and responding. Some Sensors also affect what they measures like, a thermometer at room temperature when measuring a hot substance, cools it down and gets hotter. Although they are designed to have a small or no effect on the parameters which they measure. Latest Technology Sensors are manufactured at the microscopic scales and are much sensitive than macroscopic sensor. These are called Microsensors which are manufactured using MEMS ( Micro Electromechanical Systems) Technology. Th

Wormholes

WHAT ARE WORMHOLES?           Wormholes generally are passages through Space-Time which are known to create shortcuts for long distances in the universe. They can be visualized as a tunnel with two different points in the space and time. They are predicted by the Theory of General Relativity by Einstein and Nathan Rosen and thus are also called as Einstein-Rosen Bridge. Wormholes are known to link two different points in space and act as a bridge or a tunnel which takes less time to reach farther points but they also bring with them dangers like Extreme Gravitational forces, Sudden Collapse, High Radiation and Dangerous contact with Exotic matter. Wormholes can form and collapse anytime as we don't know much about them. From the Theory of General Relativity it is quite certain that wormholes do exist but there is no sign of observing a wormhole yet. It is quite easy to imagine a wormhole, take a sheet of paper and mark two points on it. Now assume that the sheet is the space-t

Artificial Intelligence

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?           Artificial Intelligence is the ability of a digital computer system to perform tasks which require intelligence as compared to Natural Intelligence displayed by Humans. It is also defined as the study and making of "Intelligent Agents". Artificial Intelligence makes it possible for machines to learn from experience, adjust to new inputs and perform Human tasks. Most AI examples today are Self Driving Cars, Chess playing computers which rely heavily on deep learning and natural processing. Computers can be trained to accomplish specific tasks by processing large amounts of data and recognizing patterns in the data. Officially the term Artificial Intelligence was coined in 1956 but it became possible with the advancement of technology and has become much popular today. Compared to humans AI lacks many features like common sense, reasoning, perspective and most commonly Creativity like humans have. IMPORTANCE OF AI
