This allows for real-time listening in on a room hundreds of feet away by using a light bulb that may be visible in a window.
Sounds are recovered by simply observing the minuscule vibrations on the glass surface of a bulb, the light changes that these cause and some signal processing
An algorithm developed by MIT can be used to show changes invisible to the naked eye in your video clips.
Eulerian Video Magnification creates visualisations of otherwise undetectable movements and colour shifts in video footage.
The trouble with freedom
We've come to believe that freedom is the natural human condition, which only tyrants prevent everyone from enjoying - but when a tyrant is toppled, we can't know what will come next, says John Gray.
The is a new and exciting approach that makes it easier to calculate particle interactions and suggests that space and time are not fundamental parts of reality.

Just an extract from my thesis as a demonstration of the KaTeX mark up language and rendering system.
