Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

10 Lessons From 10 Years as a Social Entrepreneur

Ten years ago, I shipped the world’s first fair-trade avocados from small-scale farmers in Mexico to Europe — and my social enterprise was born.

At the time, I’d never heard of a “social entrepreneur”. I just wanted to use my business skills to help small-scale farmers transform their lives. Now, I identify as a social entrepreneur down to my bones, and my enterprise has scaled around the globe and impacted thousands of farmers in many countries.

Our mission is far from complete, but the anniversary is an occasion to reflect on the keys lessons learned during 10 life-changing years.

1. Be the change. Social entrepreneurship [...]

Fashion Library Lends You Clothes Instead of Books

Information Technology Will Lower the Price of College, or Else…

It's no secret that the inflated cost of American higher education is a major problem that needs to be addressed. The cost of college cannot be allowed to continue to rise at three times the rate of inflation for another 30 years. That is simply unsustainable. In this video, journalist Fareed Zakaria addresses three key points related to the true cost of American higher education. First, it's still a good investment despite the price. Second, it's a myth that there's a huge difference in the lifetime earnings of an engineering graduate and a non-engineering graduate.

Teaching Science in the 21st Century: Innovation Leadership in Schools

There's been incredible progress in the past few years with individual, cutting-edge teachers making some incredible gains in innovations like #geniushour, project-based learning, design thinking, the maker movement, and more more more. But how do we SCALE those kinds of innovations wider throughout our schools and throughout the education system?

We co-moderated two [...]

Free Technology for Teachers: Dozens of Alternatives to YouTube

Over the last few years I’ve seen more schools opening up access to YouTube, at least to teachers, than I had in the past. YouTube for Schools has partially contributed to that trend. Tools like ViewPure and Watchkin have made using YouTube videos in schools a little less scary too. All that said, there are still lots of schools that block access to YouTube. That’s why a few years ago I started to maintain a list of alternatives to YouTube.

This week I updated my list of alternatives to YouTube. I removed some options that have disappeared and edited information about sites that have changed. The updated list and video search engine can be found [...]

Exploring the Meaning of Spirituality – For Dummies

Exploring the Meaning of Spirituality By Sharon Janis from Spirituality For Dummies, 2nd EditionOne of the great gifts of spiritual knowledge is that it realigns your sense of self to something you may not have even ever imagined was within you.

This same light is also in everyone you know and in everyone you will ever know in the future. You may think you're limited to just your physical body and state of affairs — including your gender, race, family, job, and status in life — but [...]

Media and popular culture might portray religion and science as being at odds, but new research from Rice University suggests just the opposite.Findings from the recently completed study "Religious Understandings of Science (RUS)" reveal that despite many misconceptions regarding the intersection of science and religion, nearly 70 percent of evangelical Christians do not view the two as being in conflict with each other.
