Quantum Buzz

Hate crowds? Need your “personal space?” Negatively charged electrons do too! This is Sandra Tsing Loh with the Loh Down on Science. To understand electrons, scientists have developed a special technique called density functional theory – D-F-T for short. D-F-T is used to predict how electron crowds move in an

Whoa There, Raindrops!

A scientific storm is brewing … about the speed of rain. This is Sandra Tsing Loh with the Loh Down on Science, saying: According to physics, everything that falls has a terminal velocity. Apples, rain, people. Terminal velocity is a steady speed, where gravity and air resistance balance out. For

Taking a Dive

There’s nothing like seabirds to. . . take a dive! This is Sandra Tsing Loh with the Loh Down on Science. It’s a beautiful sight: seabirds diving head first into the water to catch unsuspecting prey. A perfect ten! But the northern gannet (GA-nit) takes gold with its flawless, high-speed

Slip n’ Slide

Slipping on a banana peel – Cartoon pratfall, or fascinating biology? This is Sandra Tsing Loh with the Loh Down on Science. What makes banana peels so slippery? That’s what Kiyoshi Mabuchi colleagues at Japan’s Kitasato University wondered. So they set up a scientific slip n’ slide! They placed a

Moon Walk

Moon walking: Not as easy as it looks! This is Sandra Tsing Loh with the Loh Down on Science. For astronauts, the moon’s weaker gravity can be disorienting. How do we know? Astronauts stumble! NASA has the blooper reels to prove it. That’s because gravity doesn’t just anchor us. It

Drip Drop

The sound of insomnia: cue the LEAKY FAUCET! This is Sandra Tsing Loh with the Loh Down on Science, on the most annoying sound ever. What causes that DRIP DRIP of a leaky bathtub? It’s not what you think! Anurag Agarwal at the University of Cambridge discovered the cause —

That’s So RETRO-grade!

Unsure of when Mercury’s in retrograde? Blame Einstein! This is Sandra Tsing Loh with the Loh Down on Science. Forwards, backwards – understanding Mercury’s kooky orbit has never been easy! Scientists were unable to do it for years. Then along came Einstein with his theory of relativity. In brief, the

Bubble Trouble

Am I tipsy, or are my beer bubbles….sinking?! This is Sandra Tsing Loh with the Loh Down on Science. Fans of the Irish stout, Guinness, are perplexed. The bubbles in their pints seem to…. sink! William Lee, a mathematician at the University of Portsmouth has BURST this case wide open!

Tipping the Tables

Next time you’re sitting at a tippy restaurant table, don’t get mad. Think Wobbleology! This is Sandra Tsing Loh with the Loh Down on Science. Wobbleology is the science of, yes, wobbly restaurant tables. New Scientist magazine coined the term. But the credit goes to these folks: researchers at Monash

Freezing Hot

Sick of waiting for your ice cubes to freeze? Maybe the water is too cold! This is Sandra Tsing Loh with the Loh Down on Science. Did you know that hot water FREEZES much faster than cold water? This paradox was first observed by Artistole centuries ago. It later became
