Summary: Veritasium is an English-language educational science channel on YouTube created by Derek Muller in 2011. The videos range in style from interviews with experts, such as 2011 Physics Nobel Laureate Brian Schmidt, to science experiments, dramatisations, songs, and—a hallmark of the channel—interviews with the public to uncover misconceptions about science.

Episode 1: Heisenberg's Uncertainty Principle Explained
Air Date: January 14th, 2013
Summary: Heisenberg's uncertainty principle tells us that it is impossible to simultaneously measure the position and momentum of a particle with infinite precision. In our everyday lives we virtually never come up against this limit, hence why it seems peculiar. In this experiment a laser is shone through a narrow slit onto a screen. As the slit is made narrower, the spot on the screen also becomes narrower. But at a certain point, the spot starts becoming wider. This is because the photons of light have been so localised at the slit that their horizontal momentum must become less well defined in order to satisfy Heisenberg's uncertainty principle.
Episode 3: Why Do Venomous Animals Live In Warm Climates?
Air Date: February 6th, 2013
Summary: As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth - why have all these venomous species evolved in the world's best holiday destinations?
Episode 4: The Original Double Slit Experiment
Air Date: February 19th, 2013
Summary: Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles?
Episode 5: What Can Frogs See That We Can't?
Air Date: March 4th, 2013
Summary: What would you see if you were drifting through space, looking back at the sun? Well its light intensity would decrease as the inverse square of distance from the sun. And you would imagine the intensity would decrease smoothly, asymptotically approaching zero.
Episode 6: Single Photon Interference
Air Date: March 13rd, 2013
Summary: What happens when single photons of light pass through a double slit and are detected by a photomultiplier tube? In 1801 Thomas Young seemed to settle a long-running debate about the nature of light with his double slit experiment. He demonstrated that light passing through two slits creates patterns like water waves, with the implication that it must be a wave phenomenon.
