The document discusses the Penrose triangle, an impossible geometric figure first created by Swedish artist Oscar Reutervard in 1934. It was later independently devised and popularized by mathematician Roger Penrose in the 1950s as the purest form of impossibility. Project Loon uses high-altitude balloons that float in the stratosphere and rise or descend into wind layers to travel where connectivity is needed, partnering with telecom companies to provide internet access directly to phones.

2. Impossible Triangle / Penrose Triangle
The geometric phenomenon is based on a mathematical
formula discovered by
Lionel Penrose, a British geneticist and his son, Sir Roger
Penrose. Penrose
triangle was first created by the Swedish artist Oscar Reutervard
in 1934.
The mathematician Roger Penrose independently devised and
popularized it in
the 1950's, describing it as impossibility in its purest form.
6. Project Loon
Project Loon balloons float in the stratosphere, twice as
high as airplanes and the weather. In the stratosphere,
there are many layers of wind, and each layer of wind
varies in direction and speed. Loon balloons go where
they’re needed by rising or descending into a layer of
wind blowing in the desired direction of travel. By
partnering with Telecommunications companies to share
cellular spectrum we’ve enabled people to connect to
the balloon network directly from their phones and
other LTE-enabled devices. The signal is then passed
across the balloon network and back down to the global
Internet on Earth.

behind the name ?
