Dennis Hong is the U.S. star in humanoid robotics
Korean fathers of that era were strict and remote. Hong’s father was engaged and intellectually indulgent. He installed a work bench in Dennis’s room when he was 4, complete with a hammer and saw. He led the children in chemistry experiments and brought home model airplanes from America.
Dennis Hong built things with scraps of wood and metal and bits of plastic. He disassembled toys and stored the parts in a chest beneath his bed.
“We spent a lot of time building things and breaking things,” said Julie Hong, Hong’s older sister. “He was the one who broke things the most and built things the most.”
…
Hong traveled to America to complete his university study, following his father’s credo, “Big fish must swim in the big sea.” He earned a bachelor’s in mechanical engineering at the University of Wisconsin and a master’s and doctorate at Purdue.
Dennis’ success illustrates several themes repeated in posts on this blog: the USA attracting talent from overseas, kids curiosity and exposure to science and engineering leading to great things, the value of strong science and engineering programs and professors. Robotics continue to progress very quickly. The economic impact of robotics is large already (largely in manufacturing) and will continue to grow dramatically. Likely robots will find their way into much more diverse areas over the next 2 decades. The Robotics and Mechanisms Laboratory, lead by Dennis Hong, seems poised to play a big role in that future.

Appropriate Technology: Self Adjusting Glasses

Self Adjusting Glasses for 1 billion of the world’s poorest see better
More than two decades after posing that question, Josh Silver [a physics professor at Oxford] now feels he has the answer. The British inventor has embarked on a quest that is breathtakingly ambitious, but which he insists is achievable – to offer glasses to a billion of the world’s poorest people by 2020.
Some 30,000 pairs of his spectacles have already been distributed in 15 countries, but to Silver that is very small beer. Within the next year the now-retired professor and his team plan to launch a trial in India which will, they hope, distribute 1 million pairs of glasses. The target, within a few years, is 100 million pairs annually.
…
Silver has devised a pair of glasses which rely on the principle that the fatter a lens the more powerful it becomes. Inside the device’s tough plastic lenses are two clear circular sacs filled with fluid, each of which is connected to a small syringe attached to either arm of the spectacles.
The wearer adjusts a dial on the syringe to add or reduce amount of fluid in the membrane, thus changing the power of the lens. When the wearer is happy with the strength of each lens the membrane is sealed by twisting a small screw, and the syringes removed. The principle is so simple, the team has discovered, that with very little guidance people are perfectly capable of creating glasses to their own prescription.
…
Oxford University, at his instigation, has agreed to host a Centre for Vision in the Developing World, which is about to begin working on a World Bank-funded project with scientists from the US, China, Hong Kong and South Africa. “Things are never simple. But I will solve this problem if I can. And I won’t really let people stand in my way.”
Cool. A couple points I would like to make:
1) this professor is making a much bigger difference in the “real world” than most people ever will. The idea that professors are all lost in insignificant “ivory towers” is a very inaccurate view of what really happens.
2) Spending money on this kind of thing seems much more important for the human race than spending trillions to bail out poor moves by bankers, financiers… It sure seems odd that we can’t find a few billion to help out people across the globe that are without basic necessities yet we can find trillions to bail out the actions of few thousand bad actors.
