I will send a copy of the e-book at no cost to schools for the blind or other educational centers that have the resources to transcribe print material into Braille or make audio books for sight-challenged readers.

LOOKING FOR A FREE SPEAKER?

If you need a speaker for your organization or classroom, please contact me. I love to make engaging presentations for children and adults on topics such as:

• Present and future exploration of space
• The rockets that will take humans back to the Moon
• Women and the exploration of space

• On July 2, 2009 I made a presentation to the Harford County Astronomical Society on the topic of Maya astronomy. A copy of my presentation can be downloaded here.

• On March 30, 2009, I gave a lecture at the University of Texas in Arlington. This event was part of the International Year of Astronomy.
