The Women Who've Won the Nobel Prize in Physics
2020 Nobel Laureate Andrea Ghez on the thrill scientific discovery.
Your Daily Equation #31 | BLACK HOLES: And Why Time Slows Down When You Are Near One
Shortly after Einstein wrote down his new equations for gravity--his general theory of relativity--a German mathematician found the first exact solution. And within that solution physicists realized that a strange new entity was lurking: black holes. In this episode, Brian Greene walks us through a visual exploration of black holes and some of the mathematics that underlies them.
Your Daily Equation #30 | What Sparked the Big Bang?
Even after astronomical observations convinced Einstein that the universe is expanding there remained the question of what drove the universe to expand in the first place--that is, what sparked the Big Bang. Brian Greene explores one prominent possibility: repulsive gravity ignited a brief but powerful burst off cosmic inflation.
Your Daily Equation #29 | Repulsive Gravity, Dark Energy, and Accelerated Expansion
One of the greatest surprises in the past few decades is the discovery that the expansion of space is speeding up. Brian Greene discusses one of our best explanations: gravity can be repulsive and can thus drive the distant galaxies to rush away ever more quickly.
Your Daily Equation #28 | Einstein, The Big Bang, and the Expansion of the Universe
Shortly after Einstein published his new theory of gravity, his general theory of relativity, researchers realized that it predicted that the universe should be expanding--a prediction subsequently confirmed by astronomical observations. And if it is expanding today, then running the cosmic film back toward the beginning suggests a highly dense and energetic starting point--the big bang.
Brian Greene employs a visual explanation of the essential ideas as well as an introduction to the underlying math that yields these conclusions.

Your Daily Equation #26: Einstein's General Theory of Relativity
Albert Einstein's General Theory of Relativity, phrased in terms of warps and curves in space and time, provides our most refined description of the gravitational force. Join Brian Greene for a visual exploration of Einstein's most profound discovery and the equations he triumphantly announced in 1915.
Your Daily Equation #27: Curvature and Parallel Motion
In his general theory of relativity, Einstein described gravity in terms of the curvature of space and time. Join Brian Greene for an introduction to the mathematics of curvature, which Einstein used to fashion his gravitational field equations.
Your Daily Equation #25: Noether's Amazing Theorem
In 1918, the phenomenal German mathematician Emmy Noether discovered a deep link between symmetries and conserved quantities, which has proven to be one of the most influential mathematical results in the development of physical laws. Join Brian Greene for an explanation of Noether's insight and the mathematical argument--in the simplest case--establishing that it is true.
Your Daily Equation #23: Ehrenfest's Theorem
Classical and Quantum Physics describe reality in completely different ways. Yet, in 1927, Paul Ehrenfest showed how Newton's equation could be derived from Schrödinger's, establishing a deep continuity in our understanding of the physical universe. Join Brian Greene for a brief explanation of Ehrenfest's essential idea as well as the mathematical manipulations he required to realize it.
Your Daily Equation #22: 8 - 2 ÷ 2 x 3 + 4 = ?
Simple arithmetic problems go viral with people proposing all sorts of different answers. It speaks to an important concept--the order of various operations matters--but, as Brian Greene discusses, is often taught in a less-than-inspirational way in the classroom (and also differs markedly from the approach of professionals). Watch this episode of YDE and let Brian know whether you agree with his assessment.
Your Daily Equation #21: Bell's Theorem
Albert Einstein and his colleagues Podolsky and Rosen proposed a simple way to rid quantum mechanics of its most disturbing feature--called non-locality--in which an action undertaken here can affect the result of a measurement undertaken there, even if here and there are far apart. John Bell came up with a way to test Einstein's vision of reality, ultimately showing that Einstein's vision was wrong.
Your Daily Equation #20: 1,000,000,001 - 1,000,000,000 = 1
When matter meets antimatter, the particles annihilate. So, in our evolving universe why is there any matter left over? Today Brian Greene discusses the recent news of neutrino asymmetry found in the T2K experiment taking place in Japan. For an in-depth discussion, check out Brian's discussion with leading researchers, "The Matter of Antimatter," https://youtu.be/qMMgsjnI1is
Your Daily Equation #19 : Euler-Lagrange Equations
Episode 19 #YourDailyEquation: Euler-Lagrange Equations: The Least Action Principle
Your Daily Equation | Episode 18: Heisenberg's Uncertainty Principle
In 1927, Werner Heisenberg derived his Uncertainty Principle, establishing that there are qualities of the world, such as the position and the speed of a particle, that can not be known simultaneously.
Join Brian for an intuitive explanation of this most famous of all quantum insights, as well as a discussion of the underlying mathematical equation. As you'll see, surprisingly, the key equation was known all the way back in the 1800s.
Your Daily Equation | Episode 17: Planetary Orbits
Newton's law of gravitation determines the trajectories of the planets and explains the patterns in their motion found by Kepler. In this episode, Brian explains the basics of planetary orbits, while also giving a nod to conic sections and the dimensionality of space.
