Customer Reviews

Brilliant program

Brilliant program. Love it. (Wish you'd put description info. in for each program though -on the podcasts- would make for easier searching)

Description Needed

Catalyst a great show generally. Pity the Podcast has no description against each episode. Current one effectively non existent

Awesome Science Show - Keeps Getting Better

Catalyst is the best science show on TV. It covers the latest stories happening in the science world and fits a lot into a 30 minute timeslot. Do yourself a favour and download some of these. Great for adults and kids to learn a bit more about the world around them. Once again ..well done ABC!
