The Great Pacific Garbage Patch/The Age of the Universe

           









Δημοσιεύτηκε στις 20 Σεπ 2015
You’ve
seen photos online of the giant, swirling garbage patch in the middle
of the pacific ocean. The reality is not quite so dramatic, but still a
serious issue to scientists and others concerned with the health of the
Earth. Today we’ll hear from Dr. Matthew Hoffman, an Assistant Professor
of Mathematics at the Rochester Institute of Technology, about how
scientists are measuring and modeling the pollution floating in our
oceans and great lakes. In the second half of our show we’ll talk about
how astronomers have learned to establish the age and size of our
Universe.

Host: Brian Koberlein
Guest: Matt Hoffman
