Put the egg down on a smooth, hard surface and set it spinning. ...[W]hen you stopped the raw egg, you only stopped the shell. The liquid never stopped swirling... so... the shell started rotating again... dragged around by its insides. ...It is a principle of physics that objects continue the same... movement unless you push or pull on them. ...[C]onservation of angular momentum.

A toaster can teach you some of the most fundamental laws of physics...

If you pour milk into your tea and give it a quick stir... liquids mix in beautiful swirling patterns... not... merging instantaneously. ...If you look down on Earth from space, you... often see... similar swirls in the clouds... where warm... and cold air waltz around... instead of mixing directly. In Britain... they form at the boundary between cold polar air... and warm tropical air... We know these swirls as depressions or s...

Learning the science of the everyday is a direct route to the... knowledge... every citizen needs...

Physics is awesome... because the same patterns are universal... in the kitchen and in the furthest reaches of the universe.

Look at... cyclists; their high visibility jackets... oddly bright... as though they're glowing... It's... the same trick the scorpions are playing...

[S]corpions... have pigments in their that take in light that we can't see and give back visible light... . The blue-green glow is thought to be an adaptation to help... at dusk. ...[I]t can detect its own glow and so... needs to do... better... hiding. It's an effective... signalling system...

The ... has produced many... spectacular images... But when you're floating... in space... how do you hold your position... How do you know... which way you're facing? Hubble has six s, each... a wheel spinning... Conservation of angular momentum means that those wheels will [tend to] keep spinning... and the spin axis will stay pointed in... the same direction... The gyroscopes give Hubble a reference direction...

The physical principle used to orient one of the most advanced technologies... demonstrated with an egg in your kitchen.

[S]imilarity in patterns is... a clue that hints at something... fundamental. ...[A] systematic basis for all such formations... This process of discovery is science: the continual refinement and testing of our understanding, alongside the digging that reveals even more...

We live on the edge, perched on the boundary between planet Earth and the rest of the Universe. ...Every human civilization has seen the stars, but no one has touched them. Our home on Earth is the opposite: messy... full of things... we touch and tweak... The physical world is full of startling variety... But this diversity isn't random. Our world is full of patterns.

[A] nugget of physics... isn't just an interesting fact: it's a tool... useful anywhere...
