    explain it in 60 seconds: Quantum entanglement
    Through ‘spooky action at a distance,’ the properties of two systems remain correlated even after they are separated.

    explain it in 60 seconds: Baryonic acoustic oscillations
    Scientists have found a way to study sound waves from the early universe to learn more about its history and contents.

    explain it in 60 seconds: Neutrinoless double beta decay
    The observation of neutrinoless double beta decay would suggest that, by itself, the Standard Model Higgs cannot give mass to neutrinos.

  • July 16, 2013
    explain it in 60 seconds: Force carriers
    Particles communicate with one another through force carriers.

June 2013

    explain it in 60 seconds: Unification of forces
    What if, like the individual threads that form a piece of cloth, all of nature’s forces can be woven together into one comprehensive force?

    explain it in 60 seconds: Plasma acceleration
    Like surfers on huge ocean waves, electrons can ride waves of plasma to very high energies.

  • March 7, 2013
    explain it in 60 seconds: Spin
    Objects as large as a planet or as small as a photon can have the property of spin. Spin is also the reason we can watch movies in 3D.

  • February 18, 2013
    explain it in 60 seconds: Spectroscopy
    Spectroscopy is a technique that astronomers use to measure and analyze the hundreds of colors contained in the light emitted by stars, galaxies and other celestial objects.

  • January 8, 2013
    explain it in 60 seconds: Bosons
    All particles fall into one of two classes, bosons or fermions. Two bosons with identical properties can be in the same place at the same time, but two fermions cannot.

    explain it in 60 seconds: Decay channel
    When particles decay, they transform into lighter particles. Physicists can predict how often a particle will decay into certain end products.

    explain it in 60 seconds: Gravitational waves
    If you could detect a bowling ball’s gravitational waves, you would know when someone threw the ball—even if you were standing outside the bowling alley.

  • September 18, 2012
    explain it in 60 seconds: Klystron
    Klystrons are at the heart of particle accelerators, radar, cancer treatments and some radio telescopes.

    explain it in 60 seconds: Sigma
    Sigma is a unit that describes how much a set of experimental data deviates from what’s expected.

    explain it in 60 seconds: Standard candle
    Your birthday cake isn’t the only thing studded with lights. Bright lights in space tell us about dark energy, the size of the universe, and more.

    explain it in 60 seconds: The muon
    Meet the Twinkie of particle physics: the muon.

February 2012

  • February 1, 2012
    explain it in 60 seconds: Cosmic microwave background
    Cosmic microwave background is the oldest light in the universe. It was set free when the universe was a mere 380,000 years old and provides a window to the early universe.

October 2011

  • October 1, 2011
    explain it in 60 seconds: Symmetry
    Symmetry is an expression of exact correspondence between things.

    explain it in 60 seconds: Synchrotron radiation
    Synchrotron light gets its name from the synchrotron particle accelerators where it was first observed.

February 2011

  • February 1, 2011
    explain it in 60 seconds: Discovery
    Discovery is the process of uncovering something new. It can be a surprise, like learning that you enjoy an exotic food, or the result of determined effort, like finding a shorter route to work.

    explain it in 60 seconds: Big bang
    The big bang refers to the start of the rapid expansion of our universe. Edwin Hubble discovered this expansion in the 1920s through observations of faraway galaxies, showing that the distances between them are growing as time rolls on. This stunning discovery is beautifully explained by general relativity—Einstein's theory of gravity—augmented by two new concepts, dark matter and dark energy.
