Happy Engineer Day -15 Sept

Bharat Ratna Sir Mokshagundam Visvesvaraya (1860.1965) was called a wizard in engineering. He was also called the precursor of economic planning in India. He took an interest not in engineering alone, but was capable of applying his talent to many allied matters connected with the development of the nation.
His learned discourse on economic planning in India entitled 'Planned Economy for India and Reconstructing India' was the first available document on the planning effort of the country and it is still held as the parent source matter for economic planners.
To commemorate the birthday ofBharat Ratna Sir M Visvesvaraya, the Council of the Institution decided to observe September 15 as the Engineers' Day every year. This is celebrated throughout the country through all the Centres of the Institution "'ith learned discourses on a theme specified by the Council every year.

Grand Challenges for engineering :

Make solar energy economical

Solar energy provides less than 1% of the world's total energy but it has the potential to provide much, much more.
Manage the nitrogen cycle

Engineers can help restore balance to the nitrogen cycle with better fertilization technologies and by capturing and recycling waste.
Provide energy from fusion

Human-engineered fusion has been demonstrated on a small scale. The challenge is to scale up the process to commercial proportions, in an efficient, economical and environmentally benign way.
Secure cyberspace

It's more than preventing identity theft. Critical systems in banking, national security and physical infrastructure may be at risk.
Reverse-engineer the brain

The intersection of engineering and neuroscience promises great advances in health care, manufacturing and communication.
