1. How realistic is space travel?

As reported in the New Scientist, Frédéric Marin, an astronomer at the University of Strasbourg, France and Camille Beluffi, a physicist who works for Casc4de, a data firm in Strasbourg, have done a thought experiment on the feasibility of reaching the nearest Earth-like planet, which happens to be Proxima b, around 4.25 million light years away, a mere 40 trillion km.

‘Coalsheviks’ want to head renewable energy off at the pass

On Wednesday morning Ben Potter’s article in the AFR Coalition fiddles as renewables remake grid told business leaders and politicians what is actually happening before their eyes.

      1. Rising: Dispatches from the New American Shore, by Elisabeth Rush

      A review by Dave Hage at Star Tribune of Elizabeth Rush’s new book Rising: Dispatches from the New American Shore says it is “a lovely and thoughtful book, so lyrical that you forget how much science it delivers.”

        Rush, who teaches creative nonfiction at Brown University, has chosen to examine climate change through the lens of American places and people devastated by rising seas and higher temperatures. Reading her book is like learning ecology at the feet of a poet rather than a scientist.
