Irwin Shapiro is a remarkable human being by almost any standard. Following his education in physics at Cornell and Harvard, he had a job at MIT's Lincoln Laboratory working on various problems in planetary dynamics, and radar ranging, when he went to a lecture and realized that a completely new phenomenon could occur in General Relativity that no one had proposed in the half-century since Einstein first proposed it. For objects traveling near a massive object like the Sun, the travel time to go from one point to another would be slightly longer than it would be if one simply divided the distance traveled by the speed of light. One might think this is simply due to the fact that light takes a curved trajectory near a massive object, rather than traveling in a straight line. But as Shapiro showed, there is an additional time delay, due to the fact that clocks tick somewhat slower in a gravitational field than they would otherwise. This effect, now known as the Shapiro Effect has become known as the 4th test of General Relativity, a test the theory passed when Shapiro and collaborators used the Haystack Observatory to carefully measure reception times for radar signal that passed near the sun. Irwin went from that triumph to Chair the Department of Earth and Planetary Sciences at MIT, and from there to Harvard to lead the Harvard Smithsonian Observatory. He remains at Harvard, where at 94 years old, as Timkin University Professor, he still teachers classes, is doing research in biology, and plays tennis several times a week!Besides all of this, Irwin is one of the most lovely and gentle scientists I have known in my career, which continued after my stint at Harvard largely because of encouragement he gave to me at a very difficult time for me. As a result, it was a pure delight to reconnect with him after many years, and have a conversation about his long career, the evolution of science in the 60 odd years that he has been doing it, and about life in general. I hope you enjoy it, and find it as intellectually and emotionally stimulating as I did. As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

There are radio wavelengths that we can't see from Earth. And to observe them from space, we need a truly huge telescope. Mary Knapp and her team proposed a project that can allow us to build such a telescope and they just recently got a NIAC grant for it.

Shep Doeleman, scientist and Assistant Director of the Haystack Observatory at MIT, explores the evidence for black holes, and describes an effort to link radio dishes around the world to form an Earth-sized virtual telescope that will make the first images of the supermassive black hole at the center of the Milky Way. This lecture took place at the Hayden Planetarium on April 13, 2015. Support for Hayden Planetarium Programs is provided by the Horace W. Goldsmith Endowment Fund.

In our final episode of Space Weather FX, we look at the Big Picture of atmospheric physics and what scientists are learning about the various layers of Earth's atmosphere. We see a summary of what scientists know about how our planet's atmosphere reacts to solar activity and other processes that create space weather.

In episode 7 of Space Weather FX we explore the famous Hallowe'en solar storms in 2003. Atmospheric scientists studied these storms and their effects on our planet's magnetosphere and our technology.

In this sixth episode of Space Weather FX, we explore the effects of space weather on global position satellite technology both in space and on the ground.

In this episode of Space Weather FX we go on a tour of Haystack Observatory's radars and learn how atmospheric scientists use them to study the effects of space weather.

In this fourth episode of Space Weather FX we look at some causes of space weather effects that come from our own stratosphere.

In this third episode of Space Weather FX we explore what happens to Earth's magnetosphere and ionosphere during a space weather event.

In this second episode of Space Weather FX we explore the ingredients that make up space weather: plasmas and magnetic fields. Learn about where we find plasmas and magnetic fields, and how they interact to create space weather.

In this first episode of Space Weather FX we explore just what space weather is and how it can affect people and technology here on Earth. Plus, you'll learn about a familiar and surprising new way to measure what space weather does to our planet's upper atmosphere!
