A visit to the toilet is included in Professor Phil Moriarty’s explanation of 3D glasses. How do 3D films give us that three dimensional effect?

It’s the most famous science equation in history… but E=mc² is not technically correct.
Temperatures below absolute zero are HOTTER than those above, explains Professor Philip Moriarty.

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.
However, experimental results in the early 1900s found that light energy is not smoothly distributed as in a classical wave, rather it comes in discrete packets, called quanta and later photons. These are indivisible particles of light. So what would happen if individual photons passed through a double slit? Would they make a pattern like waves or like particles?

The Universe in a Nutshell: The Physics of Everything Michio Kaku, Henry Semat Professor of Theoretical Physics at CUNY What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein’s [...]
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. But this is not what happens. If you had sensitive enough eyes, like [...]
NASA’s Fermi Gamma-ray Space Telescope orbits our planet every 95 minutes, building up increasingly deeper views of the universe with every circuit. The pattern reflects numerous motions of the spacecraft, including its orbit around Earth, the precession of its orbital plane, the manner in which the LAT nods north and south on alternate orbits, [...]

Mind you, the footage is directly above the epicenter, whereas the epicenter of most earthquakes (like the one in Japan) are like a mile or more below the ground and a few miles off-shore.

Emily Coren is an accomplished illustrator and scientist, and she’s figured out how to bring those two skills together to make science easier to understand: science illustrations.
On her blog, Emily regularly illustrates complex scientific topics, creating beautiful images which are half-art/half-educational resource. She illustrates the landscapes out her window on plane flights, jellyfish in the aquarium, and sexy ferns.
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?
