As Red Bull Stratos puts it:

On August 16, 1960 Joe Kittinger became a real-life superhero

It was the “highest step in the world”. Joe Kittinger made history as he ascended to 102,800 feet in a high-altitude balloon and jumped to Earth, setting four world records. Today, in an attempt to beat Joseph Kittenger’s record, Felix Baumgartner will jump from a space capsule 23 miles above earth.

In one of LIFE’s most iconic covers(above), Kittinger is pictured free falling from the sky during his journey. Tomorrow, Felix Baumgartner is set out to beat Kittinger’s record, he will jump from a space capsule 23 miles above Earth.

Safe travels, Felix. Read more about tomorrow here.

Joe Kittinger is on the Red Bull Stratos team, which is wonderfully appropriate. This cover is beyond words.

Tomorrow, he and Felix try for history.

This is beyond cool. 


This was constructed to illustrate the Tautochrone curve: a basic physics concept wherein an object will take the same amount of time to reach the bottom of the curve no matter where you drop it (assuming uniform gravity.) Cool, right? Now that I’ve explained it, you get it, right? It’s even easier to understand if you look at the little graph in the upper right hand corner which, obviously, tells you the relationship between (s)peed and (t)ime.


The Y axis actually measures arc length. Visualization is about communication, and since this targets those unfamiliar with physics it does a poor job by using potentially misleading labeling simply because it is agreed upon by the professional community.

Jargon seepage is dangerous.
