Refurbished Electronics Suppose you are looking for a new laptop for your college. You have a brand in mind, but is a little too expensive for your budget. You leave the idea behind and search a web portal for a laptop with lesser features of memory and processor for your budget. This is when you
Wireless Power Transmission Most of us at home maybe using multi-plug to connect all the electronic devices with power cords. You may have even got confused to get the right cord for unplugging it among the other cords that lead to the same outlet. At last you pull one out and hope that it is
The U.S. Geological Survey has been keeping a record of all the satellite images since 1972. This record contains all the tracks of changes that have occurred globally in the field of agriculture, cartography, geology, forestry, regional development, education, and national security. These images have been a proof of the global changes that has occurred
The web technology has become so advanced that data can be transferred in seconds from one device to another and that too within seconds. The fame of social networking sites has attracted people to upload millions of photos and videos from all over the world. One of the most common type of data transferring method
Superconductors It has been a century since the discovery of Superconductors. The discovery was made by Heike Onnes on April 8th, 1911 at the Leiden Cryogenic Laboratory in Netherlands. The first experiment involved the immersing of a mercury capillary in liquid helium. In this experiment, Heike Onnes noticed the resistance of the mercury dropping to
