                  About Industry 4.0 About Industry 4.0 Industry 4.0 is revolutionizing the way companies manufacture, improve and distribute there product. Manufactures are integrating new technologies, including Internate of Thins(IOT), cloud computing and analytics, AI, and machine learning, into there prediction facilities and throughout there operations. These smart factories are equipped with advanced sensors, embedded software, and robotics that collect and analyze data and allow for better decision - making . Even higher value is created when data from production operations is combined with operational data from ERP,  supply chain , customer service, and other  enterprise  systems to create whole new levels of visibility and insight from previosly soiled information . These digital technologies lead to increased automation, predictive maintenance , self - optimization of process improvements, ...

Benefits  of  Social Media for  Students Benefits  of  Social Media for  Students Though it has been blamed that  social media platforms have become distracting tools for students as they are not able to pay full attention and do justice to their studies once they get addicted to these technological platforms. Instead of becoming repository of information they get through school education they are more occupied with superfluous knowledge offered by social media. However on close observation it is revealed that these perceptions  about social media is erroneous and misplaced.  Social media platforms like facebook, twitter and instagram and others are interactive tools which give us including students wonderful opportunities to interact with one another. Look at the system of remote digital classroom system which help the educating institutes to impart education to the students through digital mediums from remote locatio...

Chemical  Change And Physical Change solution: Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes occur when objects or substances undergo a change that does not change their chemicalcomposition. This contrasts with the concept of chemical change in which the composition of a substance changes orone or more substances combine or break up to form new substances. In general a physical change is reversibleusing physical means. For example salt dissolved in water can be recovered by allowing the water to evaporate.   Reactants must be moving fast enough and hit each other hard enough for a chemical reaction to take place.Increasing the temperature increases the average speed of the reactant molecules.As more molecules move faster,the number of molecules moving fast enough to react increases, which results in faster formation of products.

Refrigerator  A refrigerator is a common household appliance that consists of a thermally insulated compartment and a heat pump (mechanical, electronic, or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. Refrigeration is an essential food storage technique in developed countries. The lower temperature lowers the reproduction rate of bacteria, reducting the rate of biochemical reactions so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).[1] A similar device that maintains a temperature below the freezing point of water is called a freezer. फ्रिज  एक फ्रिज एक सामान्य घरेलू उपकरण है जिसमें एक थर्मल इंसुलेटेड कम्पार्टमेंट और एक हीट पंप (मैकेनिकल, इलेक्ट्रॉनिक या क...

Cryogenic Rocket Engine Cryogenic Rocket Engine A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel oroxidizer (or both) are gases liquefied and stored at very low temperatures.Notably, these engineswere one of the main factors of NASA's success in reaching the Moon by the Saturn Vrocket. क्रायोजेनिक रॉकेट इंजन  क्रायोजेनिक रॉकेट इंजन एक रॉकेट इंजन है जो क्रायोजेनिक ईंधन या ऑक्सीडाइज़र का उपयोग करता है, अर्थात इसका ईंधन ऑर्किडाइज़र (या दोनों) गैसों को द्रवीभूत किया जाता है और बहुत कम तापमान पर संग्रहीत किया जाता है। संभवतः, ये इंजन पहुँचने में नासा की सफलता के मुख्य कारकों में से एक हैं।  शनि व्रत द्वारा चंद्रमा।

Smiling Buddha    Smiling Buddha  was the assigned code name of India's first nuclear weapon explosion on 18 May 1974. The device was detonated on the army base Rajasthan Pokhran Test Range by the Indian Army under the supervision of several key Indian army personnel. India became sixth country to have tested nuclear bombs and joined the elite nuclear club in 1998 as On 11 May 1998, 24 years after the first operation, the Atomic Energy Commission of India and the Defence Research and Development Organisation (DRDO) carried out the joint operation, known as Pokhran-II in Pokhran city of Rajsthan.  Pokhran (also spelled Pokaran) is a city and a municipality located in the Jaisalmer district of the Indian state of Rajasthan. It is a remote location in the Thar Desert region and served as the test site for India's first underground nuclear weapon detonation. मुस्कुराते हुए बुद्ध  18 मई 1974 को मुस्कुराते हुए बुद्ध को भारत के पहले परमाणु हथियार विस्फोट का...

Water Jet Cutter: A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. वाटर जेट कटर:  एक वॉटर जेट कटर, जिसे वॉटर जेट या वॉटरजेट के रूप में भी जाना जाता है, एक औद्योगिक उपकरण है जो पानी के बहुत उच्च दबाव वाले जेट, या पानी और एक अपघर्षक पदार्थ का उपयोग करके विभिन्न प्रकार की सामग्री को काटने में सक्षम है।

Nanotechnology            Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Physicist Richard Feynman, the father ofnanotechnology. In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples: • A sheet of paper is about 100,000 nanometers thick • A strand of human DNA  is 2.5 nanometers in diameter • There are 25,400,000 nanometers in one inch • A human hair is approximately 80,000- 100,000 nanometers wide • A single gold atom is about a third of a nanometer in diameter • On a comparative scale, if the diameter of a marble was one nanometer, then diameter of the     नैनो टेक्नोलॉजी:             नैनो टेक्नोलॉजी नैनोस्केल पर आयोजित विज्ञान, इंजीनियरिंग और प्रौद्योगिकी है, जो लग...
