Peter Macinnis has been involved in bringing science to the general public for many years. Formerly a science teacher, he has written a number of school textbooks and science readers, and writes for a number of magazines for adults and children. He left teaching and worked first at Sydney's Powerhouse Museum and later at the Australian Museum, before returning to teaching once more, combined with part-time writing. Over the years, he has recorded many talks for radio programs developed by the ABC Science Unit. He is now a full-time writer for adults and children. Peter has dozens of ideas for more It's True! books, including one about camels and one on disgusting food.
