At the American Association for the Advancement in Science, the National Academy of Engineering made publicly a panel which consists of 14 Grand Challenges for Engineering in the 21st century. All 14 challenges are considered priorities and in theory should make our world cleaner and safer.

Take a look at the list:

• Advance health informatics
• Advance personalized learning
• Develop carbon sequestration methods
• Engineer better medicines
• Engineer the tools of scientific discovery
• Enhance virtual reality
• Make solar energy economical
• Manage the nitrogen cycle
• Prevent nuclear terror
• Provide access to clean water
• Provide energy from fusion
• Restore and improve urban infrastructure
• Reverse-engineer the brain
• Secure cyberspace

I think everybody is satisfied with this list but I wonder how they are going to make these dreams come true. Hopefully in the 21st century.
