A few footnotes on our conversation (this may make the most sense if you listen to the podcast): <\/strong><\/p>\n Filling in a detail on that 19th century philosopher, a quote from “Death by Black Hole”:<\/p>\n Among the more bone-headed statements made by armchair philosophers, we find the following 1835 proclamation in Cours de la Philosphie<\/em> Positive by Auguste Comte (1798-1857):<\/p>\n On the subject of stars, all investigations which are not ultimately reducible to simple visual observation are … necessarily denied to us… We shall never be able by any means to study their chemical composition… I regard any notion concerning the true mean temperature of the various stars as forever denied to us (p. 16, author’s tran.)<\/p><\/blockquote>\n<\/blockquote>\n I hope everyone knows what spectroscopy<\/a> is now, and more generally, what a “spectrum” is as distinct from a range (of variation), a cluster, a flock, a dyad, a periodic table, a taxonomy or some other arrangement of things or energies. It wasn’t really explained in detail during the show but the importance of the concept was firmly underscored. You deal with spectrum-structured phenomena every day, several times. Call a friend on your cell phone (while stopped at a red light) to ask if it is better to cook a chicken in the microwave or the regular oven. Your next stop could be Wikipedia<\/a>.<\/p>\n MESSENGER stands for Mercury, Surface, Space Environment, Geochemistry and Ranging.<\/p>\n Regarding Charlie Sheen, Neil deGrasse Tyson’s tweet<\/a>, and a possible explanation for his recent behavior \ud83d\ude42 see this<\/a> (the blog post in question) and listen to the podcast after about 30 minutes.<\/p>\n A selection of some of the questions we did not cover:<\/strong><\/p>\n What exactly is the difference between galaxies moving apart because they were thrust into outer-ness (of the Universe) by the big bang, vs. the galaxies moving apart because of expansion of the universe? On a relate topic, is there a reliable way to use the expansion of the universe to argue against a speeding ticket if the cops used radar to catch you?<\/p>\n What is the perimeter of ignorance, has it moved lately, and what large changes might we hope for over the next few years?<\/p>\n If you wanted to speed up physics so we would have been where we are now several decades ago, what one fact or observation would you carry back in time to convince which historical scientist of? (I.e, let Newton in on Plank’s constant, or tell Einstein about Dark Energy.)<\/p>\n What do you say to 9\/11 “truthers” if and when you have the opportunity to speak with them?<\/p>\n What is your most interesting recent reasonably priced find. (Talking wine here.)<\/p>\n And many many more. <\/em><\/p>\n Neil deGrasse Tyson<\/a> is the Frederick P. Rose Director of the Hayden Planetarium at the American Museum of Natural History. He is the author of countless essays and several books, including Death by Black Hole: And Other Cosmic Quandaries<\/a> Very current items related to this conversation: At first glance, GJ 1214b is just another of the growing number of the super-Earth class of exoplanets. Discovered by the MEarth Project in 2009, it orbits an M dwarf in Ophiuchus in a tight orbit, swinging the planet around every 1.6 days. Late last year, GJ 1214b became the first super-Earth to have a component of its atmosphere detected when astronomers compared its spectra to models finding broad agreement with water vapor present. New work, done by the same team, further refines the atmosphere’s potential characteristics.<\/p>\n source<\/a>\n<\/p><\/blockquote>\n NASA’s humanoid robot unveiled on space station<\/strong><\/p>\n The first humanoid robot ever launched into space is finally free.
