7 . Broadcom MASTERS awards $100, 000 in prizes, inspiring and rewarding the Nation’s next generation of scientists, engineers, and innovators. The competition took place in Washington, D. C.. It’s aimed to test participants’ 21st Century skills of critical thinking, communication, creativity and cooperation in each of the STEM areas.
Elizabeth Shen, 14, Cary, N. C., demonstrated both vision and promise as an innovator, in the spirit of radio inventor Guglielmo Marconi. Elizabeth drew inspiration from the way many flowers grow to design a system for better managing the wear on a computer’s memory. Over time, many heavily used cells within computers become damaged, and the memory must be replaced. Elizabeth’s system reduces the average number of times cells were accessed, compared to other options.
Rory Hu, 12, San Jose, Calif., demonstrated excellence in science, technology, engineering or math, along with the leadership and technical skills necessary in the 21st Century STEM workforce and built a better community for tomorrow. Rory’s research on honeybees suggests that feeding bees tea polyphenols (茶多酚) and caffeine could boost their ability to learn and remember.
Mina Fedor, 14, Berkeley, Calif., used electroencephalography (脑电图学), or EEG, to measure a certain type of brain activity as people did active and passive learning tasks. Mina’s research, which found that the brain doesn’t substantially differentiate between the two different kinds of learning, could impact the way educators teach.
Jeanelle Dao, 13, San Jose, Calif., created a promising solution to a real-world problem. She invented a foot-controlled welcome mat that wirelessly automatically unlocks a door when the user puts his/her feet on the correct code. The device could help people with arthritis (关节炎) and other hand problems become more self-sufficient.
