Neil DeGrasse Tyson is unquestionably one of the best communicators that the scientific community has at the moment. He is an astronomy wonk and all of his talks on the subject are bursting with enthusiasm and passion for his chosen subject. When it comes to public outreach and inspiring new generations of scientists and science fans, I put him up there with Carl Sagan.

He was recently a guest on the Rationally Speaking podcast with Massimo Pigliucci and Julia Galaf, and he did not disappoint. In the podcast, Neil talks about Obama’s recent NASA announcement, and how it will shape space exploration in the coming decades.

Tyson states that no humans will be going to Mars any time soon. Major expeditions need major, sustained funding and this can only happen if at least one of three fundamental drivers are in place: the glorification of a deity or king, the search for wealth and the need for self-preservation. In essence, power, money and war. None of these driving reasons can currently be used to justify the landing of humans on the Red Planet.

I would note two honorable exceptions to Tyson’s rule: the International Space Station and the Large Hadron Collider. Both projects were monumentally expensive, but nevertheless none of the reasons outlined above were in place. Tyson notes that the end of the Cold War caused the US superconducting collider project to be cancelled in 1989, but this doesn’t explain why the EU persisted with the LHC as the end of the Cold War affected Europe to just as great a degree.

At the end of the podcast, Tyson discusses the recent movie Avatar and some of the movie’s more badly executed concepts. It’s a delightful discussion. I had to laugh when he talked about the creatures with their own USB ports..

This is a top-class podcast from a top-class communicator so if you get a chance, have a listen.

Rationally Speaking : Neil deGrasse Tyson and the Need For a Space Program

The Greatest Show on Earth

I’m currently reading Richard Dawkins’ latest book “The Greatest Show on Earth“. The premise of the book is simple. Dawkins presents the case for evolution in the face of those who fervently believe that is it isn’t so. His thesis uses the metaphor of a crime scene to tie together all the clues, and Dawkins comprehensively shows that there is only one suspect in town – evolution.

The evidence for evolution is overwhelming, with numerous sources such as comparative anatomy, molecular biology, fossil evidence and continental drift, all pointing to evolution through natural selection as the only reasonable explanation for the complexity and diversity of life on Earth. Evolution has even been witnessed in numerous laboratory experiments. Dawkins leaves no stone unturned in presenting the case for evolution. It’s delivered with the enthusiasm of a child, the simplicity of a teacher and the forcefulness of a barrister who knows he has an open-and-shut case on his hands.

I can’t praise Dawkins’ book highly enough. It’s full of fascinating digressions and factoids and it takes the reader on a rollercoaster trip through space and time as it presents the evidence, often in considerable detail. I don’t personally believe it will matter a jot to the beliefs of ardent creationists, but to the interested layman it will help to explain how intellectually bankrupt their beliefs are.

It was with this frame of mind that I read the transcripts of the Richard Dawkins interview on the Late Late Show (a top chat show on Irish television). I was astounded. As most people know, Dawkins authored a best-selling book on religion in 2006 called The God Delusion. It was a full frontal attack on religion, calling out the nonsense within and attempting to put religion under the microscope and into the sphere of public debate. Ryan Tubridy, the Late Late Show host, interviewed Dawkins a few times about it on radio and it always lead to some lively back-and-forth battles between Dawkins and his detractors. That was in 2006 and 2007. Now in 2009, Dawkins has published a new book on an altogether different subject, yet Tubridy could not resist the temptation to bring the discourse back to his atheism, and to inject sensationalism wherever possible – (“So what is the Vatican then? Toy Town?”, “Do you see God as believable as the Easter Bunny?”, etc.). None of these issues are discussed in Dawkins’ latest book, leading me to the conclusion that Ryan Tubridy didn’t even bother to read it.

Personally, I loved Dawkins’ clear, no nonsense answers but I couldn’t help feeling that, on Tubridy’s part, it was an opportunity missed. Is Richard Dawkins so one-dimensional that the only issue worth talking to him about is his atheism? Dawkins has much to say on the subject of evolution and why it is so important that we understand it. He is deeply passionate about science education, about the philosophy of science, about the promotion of science, about legal challenges to science, about critical thinking. In brief, we could have learned something but instead we were treated to a charade, deliberately intended to scandalise the Irish churchgoing public. This is a huge pity. By conflating Dawkins’ views on evolution with his atheism in this way, Ryan Tubridy may have muddied the waters concerning evolution, a topic that is critical to understand as we rehabilitate science and technology within the Irish education system.

“The Greatest Show on Earth” is only controversial if you are a creationist who has been vaccinated from reality. For the rest of us, it’s a rollicking good read on a vitally relevant subject.
