Atomic clocks are the most precise time-keepers we have.
But that doesn't mean they can escape the timey wimey effects of gravity.
In this episode of Great Moments in Science, Dr Karl explains how this enables super-accurate clocks to not just measure time, but height as well.
What would Dinosaurs taste like? Do dogs recognise their own breed? Why do kids get more nosebleeds than adults?
Science writer Zoe Kean & Naomi Koh Belic answers these questions and more, on triple j Mornings with host Lucy Smith.

I don t know about you, but when I wake up in the morning, there s always a song stuck in my head. It may go away for a little while if the alarm goes off and another song is playing, but the minute I let my guard down, here it comes again.
During his radio show, Australian scientist Dr. Karl Kruszelnicki was asked by a caller how to get rid of the song that was stuck in HER head. It was Lady Gaga s Bad Romance.
Dr. Karl had an easy answer for her. Chew gum.

Gazing at the heavens or just staring blankly into empty space - we’ve all done it. And there is that phrase ‘stare bear’ that refers to somebody who is staring at you.
We’ve been staring at the stars forever, and for the last six decades, we’ve put telescopes into orbit around the earth to act as our upgraded eyes.
But shifting from astronomy to medicine, staring into space can occasionally be caused by an “absence seizure” – which is a type of epilepsy. They usually happen in children between the ages of four and 14, mostly lasting less than 15 seconds - and can sometimes go unnoticed. A child could have up to 100 absence seizures in a single day – which has a huge impact on their learning and concentration.
