Have you always dreamed of building things? Does every mechanical contraption pique your curiosity, making you delve deeper into its internal working? Do you enjoy problem solving of every kind? Then engineering may be your ideal professional choice.
The field has evolved to offer solutions to almost every imaginable human problem, spawning multiple specialized realms of technology, where you could make a significant contribution. It is our endeavor to introduce you to the range of engineering branches that you could be a part of one day.
Engineering is finding creative, efficient, economical, safe and feasible solutions to any problem, in the form of processes, structures, technologies and products, by harnessing principles of nature, properties of materials and optimum use of resources. Simply put, it is about solving problems of any type, by developing an appropriate technology for the same. It is about devising solutions to make our day-to-day jobs easier and manageable. The skills required to be an engineer are problem solving ability, spatial thinking, ability to visualize, a capacity to integrate basic ideas into building a larger picture and the ability to apply what you have learned. Analytical thinking is the most important skill.

The mother of all engineering sciences, mechanical engineering is the oldest and broadest of all branches. It involves studying, designing, manufacturing and maintenance of every machine operational on Earth. From motorbikes, robotics to space vehicles, this branch contributes to the production of every piece of machinery. A mechanical engineer must master design skills, study material science, physics, structural analysis, hydraulics, mechatronics, computer-aided-engineering (CAE), instrumentation, solid mechanics, mathematics, as well as any allied technology that is part of his project. The field is the bedrock of all engineering disciplines majorly contributing to the setting up of automated assembly lines and production of heavy machinery.

The naturally evolved biological systems that abound nature dwarf all our technological achievements. The field of biological engineering is the meeting place of hitherto disconnected fields of technology and biology, creating a novel synthesis. Simply put, biological engineering is all about applying knowledge gained from biological systems (from genetics, toxicology, molecular biology and much more) to solve real world problems. It could be referred to, as a study of organic life envisioned as biomolecular machines and the creation of effective mechanisms to remedy their failings. Some of the most important subjects of study are genomics, computational biology and bioinformatics, biochemistry, tissue engineering, glycomics, bioimaging, proteomics, biological transport phenomena, biomolecular engineering, biomechanics, biophysics and carcinogenesis. Design of medical machinery and various types of implants, as well as the development of effective drug action mechanisms, is one of the prime subjects of research. Bioengineering and biotechnology are the FUTURE.
