 I'm Ira Plato. On Science Friday, we wonder about the secrets of nature and meet the scientists finding the keys to the universe, like black hole maven Jan 11. I think it's really important as a scientist not to put a belief system first. The whole point is to explore the unknown. Come explore with us. It's all on Science Friday from WNYC Studios. Fridays from noon to 2 on 88.9 FM KWC.
