 Back in the old days, if you didn't have a radio station or a television station or a newspaper of your own, you weren't able to communicate. Culture is about participation. It's about being together and exploring how we can make our society better. The world has changed. Citizens are no longer just consumers of information. So with this sort of crowd sourcing, what we call citizen science, we're really seeing how communication technology can transform science. Now our understanding is limited not by what data we can get about the universe, but by how many people we can put in touch with that data. We designed the sensing umbrella to be a node for gathering, displaying and sharing hyper-local air pollution data. Each umbrella collects nitrogen dioxide and carbon monoxide pollution levels in real time, displays it above the user's head and pushes the data to the cloud. Technology is a really important enabler so that we can communicate in really remote areas about this issue of climate change. And that's something that hasn't been possible just even 10 years ago. Rizomatica is an organization that I helped start. Basically we help people get set up and running with cellular service in their communities where no other coverage exists. In places where it's not profitable for a large operator to go, people can do it themselves. Because it's quite difficult to transfer from the field to the community from one hour to two hours. We work in the field, sometimes there are virus infections and probably anyone can take a cell phone and they can communicate quickly. What's happening now is just kind of a shockwave. What people can do. What should we do now? It's like my arms are going to fall off. Because over there comes the source, the income that I can have. We are working on a technology for people who have lost their hands to get back their hands. We used 3D printers to make things. We are trying to make it as big as possible. What's been done by partners like IMTFI is that poor people actually have very complex financial lives. Through the use of technology, it will simplify the learning process, the teaching process. This program benefits students. Mathematics has been like a disease. Most of us hate it, but this thing makes us like it. This is a huge step forward for the developing countries of Eastern Africa to have a high capacity fibre optic cable which will probably see them through the next 20 years and really bring them into the 21st century. Technology is one thing. We can do the best technology possible. But what is even better is people who use that technology to do their jobs wonderfully.
