The history and future of the New England Forest

Note: an audio version of this interview was broadcast by the WGBH affiliate WCAI, the Cape and Islands NPR station, and by KPIP in Missouri.

The forests of New England are, remarkably, a success story. They’ve recovered from attack after attack. The early settlers hacked them down, by hand, for houses, fences and firewood. Later on, the insatiable sawmills of a more industrial age ate up the lumber needed for our expansion.
Today, the forests contend with acid rain, invasive plants and exotic beetle infestations — evidence of our ever more global economy. And the future of these forests? Going forward, that’s a story that’s largely ours to shape, and narrate.

If only these trees could talk … Well, we have the next best thing – Donald Pfister, the Dean of Harvard Summer School, curator of the Farlow Library and Herbarium, a fungologist (the more erudite word is mycologist), and the Asa Gray Professor of Systematic Botany at Harvard University.
In this Faculty Insight interview, produced in partnership with ThoughtCast and Harvard Extension School, he tells the tale of the New England forest from as far back as the glacial Pleistocene era.
To help illustrate this tale, we’ve made grateful use of high resolution images of some dramatic landscape dioramas, which are on display at Harvard’s Fisher Museum, in Petersham, Massachusetts.

The End of Our Universe among other timely topics…

Note: this program was broadcast on WGBH‘s sister stations WCAI & WNAN, on Sept. 9, 2007, and picked up by KPVL, a Pacifica station, on July 2, 2013!

Want to know how the world is going to end? Just ask Russian cosmologist Alex Vilenkin. If it’s our own universe you’re talking about, well, it’s called the big crunch, and it’s going to be hot hot hot! But if it’s the multiverse, that infinitely expanding, infinitely varied and infinitely populated sea of universes, well, guess what — there is no end. Isn’t that reassuring??
Vilenkin is Professor of Physics and Director of the Institute of Cosmology at Tufts University, and also the author of a new book, called Many Worlds in One: The Search for Other Universes. He’s also a former zookeeper. And – lest I forget – he was blacklisted by the KGB

The North Atlantic Right Whale: Our Urban Leviathan

Note: This interview was broadcast on WGBH radio, Boston’s NPR station for news and culture, on April 17, 2011!

The endangered North Atlantic Right Whale is probably our closest cetacean neighbor. There are only about 350 of them in total, and they live precariously near to shore, along the Eastern seaboard, in a horrendously busy commercial shipping corridor that stretches from Nova Scotia to Florida.  Scott Kraus, the vice president for research at Boston’s New England Aquarium, and the head of its right whale research project, has studied these whales for decades, and the aquarium’s efforts on their behalf have led to dramatic improvements in right whale habitat.

But they remain nonetheless threatened — primarily by us humans.  ThoughtCast’s Jenny Attiyeh met with Kraus at the New England Aquarium recently, to discuss his latest book, which he co-edited with his colleague Rosalind Rolland, called The Urban Whale.

Dinosaurs on Thoughtcast

Back when I was working as a reporter for WNYC TV, a public TV station in Manhattan, I covered the return of the dinosaurs to the American Museum of Natural History, after a three year absence. The updated exhibition focused on the link between dinosaurs and birds. Though it’s hard to imagine a connection between the tiny city sparrow and the Tyrannosaurus Rex, there apparently is one!

“Why Does the World Exist?” with Jim Holt

Note: this interview was broadcast on the WGBH public radio affiliate WCAI, on the Cape and Islands!

In this ThoughtCast interview, science writer Jim Holt takes us on a jaunty tour of being and nothingness, existence and emptiness, quantum tunneling and the uncertainty principle. The author of Stop Me If You’ve Heard This: A History and Philosophy of Jokes, Holt lends his wit to a dissection of the puzzle of existence, which happens to be the topic of his book Why Does the World Exist? An Existential Detective Story!  A frequent contributor to The New York Times and other publications, Holt approaches his subject with a personal, philosophical and scientific point of view. But does he solve the puzzle?… You tell me!

Cosmic Evolution’s Predilection for Constant Change

Note: an audio version of this interview was broadcast by the WGBH affiliate WCAI, the Cape and Islands NPR station, and by KPIP in Missouri.

The theory of cosmic evolution is a relatively new addition to the field of cosmology, and attempts to answer the questions of who we are, where we are, and how we came to exist, among others, by taking the long view — from the big bang, to the present day.
Here’s another definition for you: “Cosmic evolution is the study of the many varied changes in the assembly and composition of energy, matter and life in the thinning and cooling Universe.”

This explanation comes from Eric Chaisson, a vigorous champion of the cosmic evolutionary theory. He’s an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, and a lecturer at Harvard Extension School, who is also the subject of this Faculty Insight interview, conducted by ThoughtCast’s Jenny Attiyeh.
And while it might leave more questions asked than answered, we hope it will give you the chance to stick your toe into deep astrophysic waters, and feel the tug of the cosmic tide…
