Oh, but MATH !?!

Hubble in orbit

Hubble was launched into Earth orbit aboard the Space Shuttle Discovery on April 24, 1990

Hubble was designed to be serviced in orbit by astronauts

Hubble servicing: 1993 1997 1999 2002 2007 ? 2010 ?

Is anyone out there?

How long would it take a rocket (at 20,000 miles per hour) to travel to... Pluto (farthest planet in Solar System) ? Alpha Centauri (nearest star) ? Andromeda Galaxy (nearest galaxy) ? How long if you could travel as fast as light?

Hello from Earth!

Search for Extraterrestrial Intelligence (SETI): Transmitting and listening...but what should we say? What might they be trying to say to us?

Math as the Universal Language
· Other ways to communicate? Knockknock-na-knock-knock....knock-knock. · Let's create our own SETI signal or "beacon" · Devise and send out a sound wave defined by "special" numbers which indicate they are some sort of message · What numbers for fequency, amplitude, modulation effects (wah-wah, phaser, etc)

Let's design a signal that somehow conveys a simple message: Something that this is clearly not some "natural" signal ­ like a pulsar ­ Something where the Frequency, amplitude and modulation (shape/sound) numbers were clearly chosen by the sender (us) to let the recipient (some alien) know that we are here.

Everyone think of a set of numbers that have a special pattern or meaning that doesn't seem random ­ seems like a person must have thought them up....we'll discuss your ideas and vote on the best one, then start designing it!

Can math be fun and exciting? Max Mutchler mutchler@stsci.edu http://www.stsci.edu/~mutchler Hubble Space Telescope http://hubblesite.org
