The word "science" probably brings to mind many different pictures: a fat textbook, white lab coats and microscopes, an astronomer peering through a telescope, a naturalist in the rainforest, Einstein's equations scribbled on a chalkboard, the launch of the space shuttle, bubbling beakers …. All of those images reflect some aspect of science, but none of them provides a full picture because science has so many facts. Science is both a body of knowledge and a process, Science is exciting, Science is useful, Science is ongoing, and Science is a global human endeavor, "Eureka!" or "aha!" moments may not happen frequently, but they are often experiences that drive science and scientists. For a scientist, every day holds the possibility of discovery of coming up with a brand new idea or of observing something that no one has ever seen before. Vast bodies of knowledge have yet to be built and many of the most basic questions about the universe have yet to be answered like:

The scientific knowledge and equipment that is needed for a particular industry, is technology. In today’s world everything we see or feel is technology. We do not have to go anywhere far to witness the strength and reach of technology in our life. Just push yourself back and think of anything you carry or do from morning to evening from the bed you sleep on, to the road you travel on to the office, to the car you travel in, to the hot case of food you carry to office, think of anything you see around from a needle to an airplane from farming to packed products we get in grocery market are just sheer example of technology. We humans are standing at a very new level of self created world and it is possible only with the help of things we have created and that is only possible because of the technology.

The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise" Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application.
