Celebrating National Science Week 2021

It’s National Science Week so we’re taking a look at all things science! First up, a new report from UNICEF says almost half of the world's kids are at really high risk because of climate change. Around the globe almost every kid is in danger from at least one climate problem; things like flooding, droughts, disease, or heatwaves. UNICEF's asking for world leaders to cut greenhouse gas emissions and better prepare for extreme weather and water shortages. Climate activist Greta Thunberg has thrown her support behind it, too. MICHELLE SIMMONS PROFILE Growing up Michelle Simmons was really interested in working out exactly how things work how the world is put together. So she became a physicist! Well, actually, she became a quantum physicist. You see computers or rather computer chips are becoming smaller and smaller and smaller over time and eventually they could be the size of atoms; the smallest thing we know of in the universe. This is quantum computing, a field where Michelle Simmons is a leading scientist. Her research focuses on building electronics at this teenie tiny scale and in 2013 she developed the world’s first transistor - one of the building blocks of electronics from a single atom! Quantum computers are more than 150 million times faster than any other computer in the world, and Simmons’ research could help revolutionise things like artificial intelligence, self-driving cars, or developing medicines. In 2018 Simmons was named Australian of the year for her pioneering efforts in science! GIANT CORAL What's 400 years old, and the size of a double-decker bus? A massive egg thing. Except it's not an egg, it's coral. It's just been discovered at the Great Barrier Reef. It measures in at more than 5 meters tall and 10.5 meters wide and it's thought to be at least 400 years old. ASTROPHOTOGRAPHY Finally today, we've asked Nat to share some of the science behind one of his favourite things photography! Now, if you look up into the night sky, you might see a few stars, but not much else. And while it might not look like it, those stars are slowly moving. Or rather, we are. A great way to show off earth's rotation is to take super long exposures of the night sky, sometimes called star trails. Cale and Nat give it a shot! __________________________________________ Make sure to like & subscribe to our videos if you want to stay in the know! 👉 Subscribe https://www.youtube.com/behindthenews...
