In the month of July, I am running a special promotion on Twitter that offers a chance for a free, personally autographed copy of my latest book:

Flashes of Creation

George Gamow, Fred Hoyle, and the Great Big Bang Debate

Here’s how it works:

Follow @phalpern on Twitter.
Pre-order a copy of Flashes of Creation. It can be electronic or hardcover, from any bookseller.
Think of a good question about science.
Tweet your question to @phalpern, with the hashtag #FlashesOfCreation and a picture that has proof that you pre-ordered a copy of Flashes of Creation. Make sure there is no confidential or personal information in the photo.
One entry per person, please. Promotion ends July 31 at 11:59 PM, Eastern Standard Time (New York Time).
I will answer your question, and enter you into the drawing, which will take place on August 1.
On August 1, I will randomly select, from among the entries, 5 winners from the United States and 5 winners from other countries around the world.
If you are one of the winners, I will DM you for your mailing address and what personal inscription you would like on the book. Then I will autograph and mail the book to you, after it is published on August 17!
Books subject to availability. If there is a production or mail delay, that might delay fulfillment of the books.
This is an author-sponsored promotion under the auspices of Paul Halpern LLC. It has no affiliation with Basic Books, Hachette, University of the Sciences, or any other organization.
