SCMP Reporter

Zee Leung Man-chi, 16

Tang King Po School

Mathematics is the greatest invention. It's a common logic around the world. Its rules always work. It explains  the natural law and has  become important for communication. It's actually indispensable to humans. Science, engineering, economics, management, mechanics - everything depends on mathematics.

Alice Yeung Min-wing, 15

SKH Bishop Mok Sau Tseng Secondary School

The light bulb is the world's greatest invention. Without it, our world would be less wonderful and colourful. Not only does it make life much more convenient, it is also used in advertisements and decorations.

Mathew Liu Pak-hong, 14

SKH Bishop Mok Sau Tseng Secondary

School Music, rather than English, is the best international language and the greatest invention in the world. It can break down language barriers and allow people to share their happiness, anger, sadness and fear. It can also convey messages.

Bosco Wong Chun-him, 17

St Joseph's College

It has to be paper, which allows us to  record history and pass on  our messages. Paper, from which books are made of, helps spread knowledge and wisdom. We also read the daily news which is  printed on paper.

Carly Kwok Pun-lai, 17

Christian Alliance S.C. Chan Memorial College

Without a doubt, motors are the world's greatest invention. From domestic electrical appliances to transportation, everything needs motors to run. Just imagine. How could you go to the US if there were no planes or cruise ships?

Gigi Lam Chi-ying, 17

Shun Tak Fraternal Association Cheng Yu Tung Secondary School

The wheel.  Without wheels, cars and machines would be useless. We don't know who to thank for the wheel, but think of what the world would be like without it.

Patrick Lee Pak-chuen, 17

La Salle College

Language! Through language we can  explore our ideas and convey our thoughts to expand the  frontiers of technology. Language makes us unique from other species.

Sally Lam Wai-ying, 17

PLK Vicwood K.T. Chong Sixth Form College

Electricity. Without it, we would not have heating, air-conditioning or light. The world would become primitive. We would have to rely heavily on nature. We could freeze to death in the cold winter. Electricity definitely is the best.

Tracy Lee Cheuk-sze, 15

Diocesan Girls' School

Without a doubt it's electricity. Electricity supports our daily activities and expedites the development of society. It ensures   a hi-tech and prosperous future  and is indispensable to the contemporary world.

Andrew Leung Ho-yan, 14

Wah Yan College, Kowloon

I would say vaccines. They can prevent various diseases and infections,   saving many people's lives.



Question of the week: What is the world's greatest invention?
