There are scientists, and then there’s Niraj Lal. As a youngster exploring the sandy beaches of Hawaii to a teenager in classroom labs in Canberra, Niraj Lal lives and breathes all things science. When he’s not researching nanophotonics in an effort to make solar electricity cheaper, he is travelling the countryside taking science to school students — and making it super fun. From explosions to lasers to solar-powered gadgets, bubbles and slinkies, there really isn’t anything that excites ‘Nij’ more than the world of science.
