The kitchen knife is one for the future that gives basic information on freshness and bacteria infection of food materials and food, and nutrients at a glance. The knife has sensor and system on its tip itself to sense ingredients of food materials, and the information is known to a user through Smart screen. the smart knife include not only providing information but also negative ions. it can keep freshness for a long time and block the virus. the negative ions is effective to organic groceries. especially It can block decomposition by ethylene gas and it help to keep freshness for a long time because negative ions have water molecular and it cover groceries surface. and it also help to prevent oxidation and keeping freshness to meat and fish you can choose a option of two ways voice recognition or touch screen, and you can conveniently get some information through voice recognition in cooking when you see the screen with holding the knife. it is very inconvenient to hold. so I

some inventions are glamorous—microchips and fiber-optic cables spring to mind. Others are quieter and more humble, but no less important. Pumps and compressors certainly fall into that category. Try to picture life without them and you won't get very far. Take away pumps and you'll have nothing to push hot water through your home central-heating pipes, and no way to remove the heat from your refrigerator. Might as well start walking too, because you won't be able to blow up the tires on your bicycle or put gasoline in your car. From jackhammers to air conditioners, all kinds of machines use pumps and compressors to move liquids and gases from place to place. Let's take a closer look at how they work! Bicyclists use bicycle pumps on a very regular basis, but most probably never stop to think how they actually work. The purpose of the bike pump is to force air out of the

Hello friends The gyroscope, or gyro for short, adds an additional dimension to the information supplied by the accelerometer by tracking rotation or twist. An accelerometer measures linear acceleration of movement, while a gyro on the other hand measures the angular rotational velocity.                                                                                            Every smart mobile phone has various sensor in built.Today we are going to learn "How to take data from mobile gyroscope". Let's start............... Step:1 Just open android studio and click on make new project.Now enter into programming/Development mode. If you don't know how to do that then go to this tutorial.

By:Anubhav A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium.  Uranium-fuelled nuclear power is a clean and efficient way of boiling water to make steam which drives turbine generators. Except for the reactor itself, a nuclear power station works like most coal or gas-fired power stations. What is atomic energy?   It's not immediately obvious but tall buildings store energy—potential energy. You have to work hard to lift bricks and other building materials up off the ground into the right position and, as long as they remain where you put them, they can store that energy indefinitely. But a tall, unstable building is bound to collapse sooner or later and, when it does so, the materials from which it was built come crashing back down to the ground, releasing their stored potential energy as heat, sound, and kinetic energy. Atoms are much the same. Some large atoms are very stable and quite happy to stay as t
