To celebrate the publication of my new book, The Science of Light, I’ll be signing books til they run out! Thanks to Hudson Co-op for hosting (Thanks Laura, Sue and Kat!) and to WordUp Community Bookshop for being the bookseller of note (thanks, Veronica!). There will be light related giveaway, a drawing for a copy of THE SCIENCE OF LIGHT: Things That Shine, Flash and Glow (Holiday House)

at Hudson Co-op, 817 W. 187th Street. Come say Hi!
