Quanta Magazine Season 2018, Episode 23: Albert Einstein, Holograms and Quantum Gravity

1

Richard Schwartz: In Praise of Simple Problems

Mathematician Richard Schwartz talks about why he's attracted to the hidden depths of simple problems.

2

Ed Boyden on the Promise of Expansion Microscopy

Ed Boyden of MIT’s Media Lab, the inventor of expansion microscopy, explains how the technique could illuminate deep mysteries about how the brain works and improve cancer diagnosis, among many other advances.

3

Erich Jarvis on Theories About the Origin of Vocal Learning

Neuroscientist Erich Jarvis discusses how the brain circuitry for vocal learning in songbirds and humans evolved from systems for controlling body movements and why so few species have this ability.

4

Daniel Goldman and His Smart Robots

Goldman explains how “smarticles” work together to demonstrate collective behavior.

5

Barbara Engelhardt on How to Improve Statistical Analyses of Genomes

Barbara Engelhardt, a computer scientist at Princeton University, explains why traditional machine-learning techniques have often fallen short for genomic analysis, and how researchers are overcoming that challenge.

6

Günter Ziegler Seeks God’s Perfect Math Proofs

Günter Ziegler describes one of the most famous and beautiful proofs in "Proofs From THE BOOK," a book he co-authored with Martin Aigner.

7

Donald Richards: A Revealer of Secrets in the Data of Life and the Universe

Donald Richards discusses the statistical rule-of-thumb he wishes everyone knew.

8

Michela Massimi: Defending the Philosophy of Science

Michela Massimi argues that the philosophy of science doesn’t have to be useful to scientists for it to be useful to humanity.

9

Lisa Manning on the Dynamics of Glasses and Embryos

Lisa Manning, a physicist at Syracuse University, describes how the physics of glassy materials helps to explain how some organs assume their correct shape during embryonic development.

10

Carina Curto on How Physicists Can Think About Neuroscience

Carina Curto, a mathematician at Pennsylvania State University, explains how her background in theoretical physics helps her tackle daunting problems in theoretical neuroscience.

11

Jessica Whited on Limb Regeneration and the Axolotl Genome

Jessica Whited is a biologist who studies limb regeneration at Harvard Medical School and Brigham and Women’s Hospital. Here, she explains how genomic information for the salamander called an axolotl will help us understand the potential for regrowing limbs in humans and other animals.

12

Cohl Furey on the Octonions and Particle Physics

Cohl Furey explains what octonions are and what they might have to do with particle physics.

13

Alessio Figalli: A Traveler Who Finds Stability in the Natural World

The mathematician Alessio Figalli is rarely in one place for very long. But his work has established the stability of everything from crystals to weather fronts by using concepts derived from Napoleonic fortifications.

14

Caucher Birkar: An Innovator Who Brings Order to an Infinitude of Equations

Birkar discusses the need for originality in mathematics and in life.

15

Akshay Venkatesh: A Number Theorist Who Bridges Math and Time

Akshay Venkatesh on his mathematical working style, which took him many years to discover.

16

Constantinos Daskalakis: A Poet of Computation Who Uncovers Distant Truths

Constantinos Daskalakis on why he studies the interface between theoretical computer science and human behavior.

17

2018 Fields Medal Coverage at Quanta Magazine

Mathematicians Caucher Birkar, Alessio Figalli, Peter Scholze and Akshay Venkatesh have been awarded the Fields Medal. Computer scientist Constantinos Daskalakis won the Nevanlinna Prize.

18

Rosaly Lopes on Volcanoes Throughout the Solar System

Rosaly Lopes explains why it’s worth exploring the huge variety of volcanoes on other worlds.

19

Tomas Bohr on Performing the Double-Slit Experiment with Bouncing Droplets

Tomas Bohr explains the significance of the double-slit experiment in exposing the weirdness of the quantum world.

20

Renee Reijo Pera on the Importance of Timing in Embryo Development

Stem cell researcher Renee Reijo Pera of Montana State University explains how the timing of developmental events in the early embryo can subtly affect health many years later.

21

Mario Jurić on How Astronomy Is Changing

Just as mathematics transformed physics from a philosophy into a science, data and computation are transforming science today, says Mario Jurić. He’s leading the push to get astronomy ready for the torrents of data that are about to flow. Mario Jurić explains how the nature of what it means to be an astronomer is changing.

22

Valeria Pettorino on Learning About Dark Energy With the Euclid Satellite

Valeria Pettorino discusses the prospects of learning about dark energy with the Euclid satellite.

23

Albert Einstein, Holograms and Quantum Gravity

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

24

Why Different Parts of a Coffee Mug Produce Different Pitches

The Stanford mathematician Tadashi Tokieda demonstrates one of his physics “toys”: the curious higher and lower notes you hear when tapping a coffee mug with a spoon.

25

Martin Rees on the Future of Science and Humanity

The University of Cambridge astrophysicist, Astronomer Royal and popular author discusses how our society can benefit from science while avoiding potential pitfalls.

26

What Is Emergence?

How do extraordinarily complex emergent phenomena — like ants assembling themselves into living bridges, or tiny water and air molecules forming into swirling hurricanes — spontaneously arise from systems of much simpler elements? The answer often depends on a transition in the interplay between the elements that resembles a phase change.
