From the ground breaking and life saving to the wacky and implausible, Dr Karl Kruszelnicki reveals some of the best moments in science.

    The Greatest Moment in Science

    The Greatest Moment in Science

    Dr Karl was first heard on the wireless in 1981 when he convinced Triple J that a talk about the space shuttle would be good listening because he had applied to be a NASA astronaut.

    The power of smell can't be understated — our noses don't just sniff out tasty treats, they can also alert us to danger. 

    In this episode of Great Moments in Science, Dr Karl tells the story of a super-sniffer who might've unlocked a powerful diagnostic tool.

    How tall is time? Well, it's all relative

    How tall is time? Well, it's all relative

    Atomic clocks are the most precise time-keepers we have.

    But that doesn't mean they can escape the timey wimey effects of gravity.
