Engineers make things happen.
1. Electrification - the vast networks of electricity that power the developed world.
2. Automotive - revolutionary manufacturing practices made the automotive the world's major mode of transportation by making cars more reliable and affordable to the masses.
3. Aeroplane - flying made the world accessible, spurring globalisation on a grand scale.
4. Safe and Abundant Water - preventing the spread of disease, increasing life expectancy.
5. Electronics - vacuum tubes and, later, transistors that underlie nearly all modern life.
6. Radio and Television - dramatically changed the way the world received information and entertainment.
7. Agricultural Mechanisation - leading to a vastly larger, safer, less costly food supply.
8. Computers - the heart of the numerous operations and systems that impact our lives.
9. Telephone - changing the way the world communicates personally and in business.
10. Air Conditioning and Refrigeration - beyond convenience, it extends the shelf life of food and medicines, protects electronics, and plays an important role in health care delivery.
11. Interstate Highways – 1,000s of miles of highway allowing goods distribution and personal access.
12. Space Exploration - going to outer space vastly expanded humanity's horizons and introduced 60,000 new products on Earth.
13. Internet - a global communications and information system of unparalleled access.
14. Imaging Technologies - revolutionised medical diagnostics.
15. Household Appliances - eliminated strenuous, laborious tasks, especially for women.
16. Health Technologies - mass production of antibiotics and artificial implants led to vast health improvements.
17. Petroleum and Gas Technologies - the fuels that energised the 20th century.
18. Laser and Fibre Optics - applications are wide and varied, including almost simultaneous world-wide communications, non-invasive surgery, and point-of-sale scanners.
19. Nuclear Technologies - from splitting the atom, we gained a new source of electric power.
20. High Performance Materials - higher quality, lighter, stronger, and more adaptable.
