Some of you may be aware the Prof is currently in Sydney for the first leg of a speaking tour around Australia.
We've just had word that any periodicvideos fans who wish to see his lecture on Wednesday (21st of Sept) can come along and get a free visitor's pass.
He'll be lecturing at 11.45am-12.30pm on his beloved topic of green chemistry and how it can improve the world.
He'll also be around (briefly) after to say hello.
The lecture is on level 3 of the Hilton Hotel on George St as part of Chemeca Conference.
