2017 Look Back – 2018 Look Forward

2017For this end-of-the-year/start-of-the-year  How on Earth show, we look back to 2017 with clips from some of our features from the past year: selections about tracking methane leaks, ketogenic diets, using MDMA to treat PTSD, gravitational waves, the solar eclipse, space missions, and the politicization of science.  Those are just a few of the topics we covered in 2017, which also included: the continuation of the Our Microbes, Ourselves series, global warming and climate change, research about aging, mutant proteins, how humans have altered nature, future technologies, nuclear tests and the Van Allen belts, biofuels, extinctions following an asteroid impact, monorails, life expectancy in America,  observing stellar occultations by objects in the distant solar system, space shields for satellites, virtual colonoscopies, the Search for Extraterrestrial Intelligence (SETI), chronic fatigue syndrome, protecting pollinators, testing our drinking water, cancer, the Long Now foundation, citizen science, fracking, and more!

First Detection of Gravitational Waves

ligoInterview with LIGO Scientist Dr. Matt Evans (6:22): The recent big news in physics was the announcement of the first direct detection of gravitational waves.  The detection was made by the LIGO project, which stands for “Laser Interferometer Gravitational-Wave Observatory”.  Reports have said that this is a confirmation of general relativity and a new way to view the universe.  To help us understand that, and why this is such a significant achievement, we have on the phone Dr. Matthew Evans, an Assistant Professor of Physics at MIT.  Dr. Evans is a member of the LIGO Scientific Collaboration and the chair of the Advanced Interferometer Configurations working group.  His research focus is on gravitational wave detector instrumentation, and the fundamental sensitivity of gravitational wave detectors.

And here you can see the signal and hear the “chirp” of a graviational wave!
