Astrophysicist Mario Livio: A Twitterscript
Shubha Bala, associate producer
For the past few interviews, we have been diligently tweeting away while Krista converses with our guests. We hope that this is a unique way for you to experience some of the highlights — and get the conversation started — before you experience the full edited (or unedited!) show.
After our interview with Mario Livio, we all sat down to discuss what constitutes a good tweet. So, this week, we ask you: seeing the entire tweeting transcript below, what tweets are helpful? Do links help? Is it too much to break information between tweets?

- For the next 90 minutes, we’ll be live-tweeting Krista’s ISDN interview with Mario Livio, a Romanian astrophysicist who grew up in Israel.
- Mario Livio’s latest book is “Is God a Mathematician?”
- Livio asks if mathematics discovered or is it an invention of the human mind. Picks up from Krista’s interview with two Vatican astronomers.
- "Mathematics turns out to be too powerful in describing all these things." -Mario Livio
- Mario Livio: Newton takes observations that aren’t so accurate, + his mathematical equations are more accurate than the observations!
- Livio: the theory of knots are very important application for string theory even though it was initially thought to have no application.
- Livio: The conclusion I reached about math being discovered or invented is that the question is being posed wrong. It’s a mixture.
- Ex. of mixture: imaginary numbers like square root of -1. We invent the concept and then we discover the relationships among these concepts.
- Ancient Greeks invented concept of prime numbers. And then the discoveries were forced upon us.
- Livio: Roger Penrose, mathematical physicist: three worlds and three mysteries - physical world, consciousness, mathematical forms.
- Penrose’s 3 mysteries: 1) out of the physical word, consciousness 2) consciousness gives access to math forms 3) math explains phys. world
- Livio: Chomsky will tell you that there is more universality to languages than we think.
- Livio “The Microsoft Effect”: once a particular OS starts to dominate, all have to adapt it. Mathematical notation is a little bit of that.
- Mario Livio: “Our perception system is universal. This had to help in inventing natural numbers like 1,2,3,4,5…”
- "Like beauty in the arts, it is somewhat more vaguely defined [in mathematics] …but perhaps it is a little bit more defined." -Mario Livio
- We try to formulate a few laws of physics + try to explain all phenomena. We do the same thing in mathematics - like in symmetry. -M. Livio
- "I have heard very few people think that Einstein’s general theory of relativity is not beautiful." -Mario Livio, astrophysicist
- Mario Livio: You could argue that the principal behind Einstein’s general relativity is simpler than Newton’s gravity.
- M. Livio: Symmetry is a quantity that does not change. Mathematicians came up with a system to describe ALL these symmetries. Group Theory.
- Funny moment where Krista starts to ask Livio about his love of art and Mario Livio responds, “You seem to be well prepared.”
- Mario Livio, in response to Krista’s question: “I don’t have a good explanation for my passion for art.”
- Livio: “…it would be false to say that science + art have influenced each other. Or that science + religion have influenced each other.”M. Livio: “A person who feels a need for God does not want a God that created the universe and then left the universe to its own devices.”
- M. Livio, picking up on that last point: “Science has nothing to say about this. … People try to force the connection.”
- M.Livio-ppl who try to say Genesis is completely accurate scientifically does science & religion a disservice
- M.Livio-Is God a Mathematician? “I mean God as an Einsteinian God-synonym to the working of the cosmos.”
- M.Livio-Physics has changed over time but “Mathematics has evolved, but the math the ancient greeks did is still true today.” Eternal truth?
- M.Livio-As physics became more predictive, people went away from religion to talk about nature - talked about precise sciences
- M.Livio-cont. a development of 20th century-with quantum physics, things are no longer deterministic, can only calculate probabilities
- M.Livio-“Biology today is..at the state physics was…..-many of the major breakthroughs are yet to be made”
- Krista tells a funny story of Goedel, accompanied by Einstein, applying for US citizenship - http://www.ias.edu/people/godel/institute
- M. Livio - About math and life… well “in science, unless you have a well defined problem it is virtually impossible to try to answer it”
- Livio-“Things like life these are inherently complex situations where..often I don’t..know what question to pose, let alone find the answer”
- Livio-April 24 is Hubble 20 year anniversary. He talks about the importance of Hubble images - http://hubblesite.org/gallery/album/
- Krista and M. Livio recall SOF interview about human & mathematical limits with Janna Levin - http://bit.ly/axpPBy
- M.Livio-pushing boundaries-we used to think the earth was the center of a universe, and now “200 galaxies like ours just in the observable”
- M.Livio - but each discovery we make, we find out there’s something “even more mysterious”
- M.Livio-In all this, our physical selves seem more&more minuscule, but our minds making the discoveries are more&more important & central
