Dr Shane, Dr Krystal and Chris KP go back in time for this penultimate episode. The theme of the show is to "take three items back in time" that could positively influence future culture. The team discuss taking back the thin lens formula, the concept of zero, penicillin, parabola shape, a battery and more.

News topics cover the amount of plastic in the oceans, new CSIRO RV Investigator ship and how dragonflies use the predictive flight method to hunt their prey.
