Ep: 93: John Mather: Nobel Laureate in Physics and senior project scientist on the James Webb Space Telescope

John Mather is a Senior Astrophysicist in the Observational Cosmology Laboratory at NASA’s Goddard Space Flight Center. He is also the Senior Project Scientist on the James Webb Space Telescope. His research centers on infrared astronomy and cosmology. He was the chief scientist for the Cosmic Background Explorer and received the Nobel Prize in Physics in 2006 for his precise measurements of the cosmic microwave background radiation.  He has served on advisory and working groups for the National Academy of Sciences, NASA, and the National Science Foundation.

 

Some interesting insights from this episode:

  • The James Webb Space Telescope uses infrared technology which allows us to see through the dust clouds to see stars being born.
  • “Maybe the formation of life doesn’t require a rare and exotic coincidence but maybe it’s something that always happens when given the chance.”
  • Like Neil deGrasse Tyson, John visited the Hayden Planetarium as a kid which ignited his early passion for astronomy.
  • He didn’t have his entire career mapped out but rather followed his curiosity and said yes when opportunity would present itself.
  • While society holds the theorists in higher regard than the experimentalists like John, that never deterred him.
  • Stephen Hawking called his discovery of hot and cold spots in the cosmic background radiation “The most significant scientific discovery of this century if not of all time.”
  • COBE took 15 years from inception to launch and the James Webb 27 years but John was able to stay the course on both, keeping himself and his teams motivated along the way.
  • His secret to success isn’t being the smartest one in the room and always knowing the answer but rather not being afraid to ask others.

Ep 52: Neil deGrasse Tyson: Astrophysicist and Master of the Universe

Neil deGrasse Tyson is an astrophysicist with the American Museum of Natural History and Director of the Hayden Planetarium.  He is also the host of the hit radio and Emmy-nominated TV show StarTalk, and the New York Times best-selling author of Astrophysics for People in a Hurry and the author of a number of other notable books, the latest of which is titled Letters from an Astrophysicist.  He earned his BA in physics from Harvard and his PhD in astrophysics from Columbia.

 

Some interesting insights from this episode:

  • He knew he wanted to become an astrophysicist since the age of nine when he visited his first planetarium.
  • His passion for discovering the universe enabled him to push past the racism and all the societal pressures holding him back. He would not allow anything to interfere with his ambitions.
  • He finished middle of his class in high school because he was valuing the joy of learning while others were valuing high grades. He had lots of interests outside of school and was never driven by grades.
  • “When I wonder what I am capable of as a human being, I don’t look to relatives, I look to all human beings. The genius of Isaac Newton, the courage of Joan of Arc and Gandhi, the athletic feats of Michael Jordan, the oratorical skills of Sir Winston Churchill, the compassion of Mother Teresa. I look to the entire human race for inspiration for what I can be – because I am human. My life is what I make of it.”
  • It’s highly likely that there is extra-terrestrial life. The top four ingredients of life on earth are the top four chemically active ingredients in the universe. In addition, the speed at which life formed on Earth, the age of the universe, and the number of planets and galaxies all suggest that there are life forms outside of the Earth.
  • He does not believe in a God. If there were such a divine force, it would manifest.  If there is something we don’t understand and can’t explain, his first thought if not whether it might be divine but rather, how can he experiment on it further to better understand it.
  • He has 14 million Twitter followers. He views his role on social media as enlightening the public to what is objectively true so people can have informed opinions.
  • Physicists recently detected gravitational waves originally predicted by Einstein over a century ago. These waves were produced in a collision between two black holes 1.3 billion light years away.
  • “Excellence is whether you’ve done the best you can given whatever the talents available to you.”
