"My favorite element is . That's mainly because of this organism... a ... a tiny... organism that lives in the surface of the ocean..."

"[A]ll of these platelets, this really intricate structure... is made of so calcium is incorporated into this structure..."

"This organism lives, and it dies, and quite often when it dies, the broken fragments... drift down... and... can build up... on the floor of the ocean, and over geological time these beautiful little platelets of calcium carbonate become squashed into rocks of calcium... [A]s techtonic plates move around and seas come and go, those rocks can get lifted up and so this... is what the White Cliffs of Dover are made of..."

"[M]ost of the south coast of England is underlain by a great layer of this calcium carbonate, mostly made of this one amazing organism."

"So after the calcium has been part of the cliffs it can crumble down... It goes back into the ocean and this cycle starts all over again."

"Humans have found this a very useful material. Drawing this diagram with this piece of is a lovely thing to do because... I drew it with itself. So the tiny... fragments of old marine creatures sitting around in here are now what's stuck to the blackboard making up my drawing of the . So calcium is my favorite element, just because of this cycle."

"[T]here are these very famous images in ' of s swimming, and they've always got these trailing bubbles. ...[N]o one really thought about it until a few years ago at the University of Bangor, a couple of fluid dynamicists... had a bit of think, and it turns out that what the penguins do is really... cool! ...They are constantly preening. The feathers are the most important thing a penguin has because they are its insulation and they are a large part of how hydrodynamic it is. How easy it swims through the water. ...Before the penguin goes down to dive, and they can be quite long dives, the penguins all fluff up their feathers and trap gas... bubbles underneath."

"And then they go down, and they go hunting for fish... [I]t comes time to go back up to the surface and hop out onto the ice past the s."

"[A]s they're starting that swim upwards they... unfluff their feathers and... release... a coat of bubbles... [T]hose bubbles... are inducing . It's just like the same reason a golf ball has dimples, the bubbles are reducing the drag on the penguin and a penguin that is producing bubbles can travel 50% faster... So it stands a much better chance of getting past the leopard seals now, onto the land."

"So this is brilliant, because it's this wonderful interaction of all sorts of things. It's a physical process. The reason the bubbles come out as the penguin swims up is because the pressure is decreasing, and the bubbles are expanding, so they can come out of the feathers."

"They are reducing... drag, which is one of the most complicated problems in , and the penguins just... do it."

"And... it changes the ecosystem because the penguins can then survive in conditions they would not otherwise be able to survive in."

"So penguins use bubbles, and I think that's brilliant!"

"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."

"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..."

"[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..."

"[[w:Scorpion|[S]corpion]]s... 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..."

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

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

"[[w:Tonic water|[T]onic water]] glow[s] under ultraviolet... because the ... is fluorescent. ... ink is also acting as an ultraviolet detector..."

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

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

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

"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. ...[[w:Angular momentum#Conservation of angular momentum|[C]onservation of angular momentum]]."

"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."

"This is why I love physics. Everything you learn will come in useful somewhere else, and it's all one big adventure..."

"As far as we know, the physical laws we observe... on Earth apply everywhere... You can test them for yourself."

"In the past, information was treasured... These days we live on the shore of an ocean of knowledge... with regular s that threaten out sanity."

"The basic principles alone often won't provide specific answers, but they'll provide the context needed to ask the right questions. And if we're used to working things out... we won't feel hopeless when the answer isn't obvious..."

"Critical thinking is essential... especially with advertisers and politicians all telling us... they know best."

"We are responsible for our civilization. We vote... choose what to buy and how to live... collectively [as] part of the human journey."

"No one can understand every... detail of our complex world, but the basic principles are fantastically valuable tools..."

"This is what separates science from other disciplines—a scientific hypothesis must make specific testable predictions. ...[Y]ou have to look hard for consequences that you can check for, and especially... that you can prove wrong."

"Science is always trying to prove itself wrong, because that's the quickest route to finding what's actually going on."

"You don't have to be a qualified scientist to experiment with the world. Knowing some basic principles will set you on the right track... [I]t doesn't even have to be an organized process..."

"This book is about linking the little things we see every day with the big world we live in."

"Science is not about 'them', it's about 'us'... we can all go on this adventure in our own way."

"[B]eing at sea during the , when it arrived in the UK... back in 2013. I was on the in the North Atlantic and the swell... the during that storm was 10 meters during the middle of it."

"Being up on the bridge and watching these waves roll in... We were sitting bow into the wind. We were studying high wind gas exchange so... we'd gone out there for those conditions. The chief scientist was incredibly happy when that storm came around."

"[J]ust being on the bridge when that storm came along... and watching those waves roll towards the ship and... rear up in front of us. It wasn't everyone's favorite thing, but I felt privileged to be there."

"[W]e have all these dry numbers and significant wave height is one of them... [W]atching what it really means for a significant wave height to be 10 meters and thinking about how small that is compared to the depth of the ocean... It's like... having a swimming pool and... blowing tiny ripples across the top. ...Being in that situation was... fascinating and fun... I wouldn't want to do it every day, but it was... a special experience."

"We know how that graph goes... Wind speed... along the x-axis, some measure of gas flux... along the y-axis, and we knew at the time that the graph only went so far to the right... [W]e were putting dots... on the graph that had not been there before... So there's that added thing of being there with the right equipment at the right time to... measure something that has not been measured directly before..."

"It wasn't my first time at sea. It was my first time in waves that big."

"It's not a linear path. I did my PhD... in experimental explosion physics... I was interested in the , which was much harder then than it is now. This was before CCDs and CMOS sensors were built into things like high-speed cameras... [Y]ou had to do it the old-school way. ...[I]t was interesting and challenging and I liked building that kind of experiment. Looking at small things that were too quick... to see directly. But I never wanted to do [explosion physics]..."

"So after I finished my PhD I looked around for another topic, and I found bubbles... [T]hat... took me to Scripps, to the lab of Grant Deane and he... showed me the ocean... indirectly... I was in that lab. I had these experiments on bubbles. They involved things I understood, s and tanks and... s... [T]here was this frame by the door... and after three weeks they all started fussing around it, and I realized this thing, which I now know is just a surface following buoy, was their gateway to another world."

"The day they carried... [the surface following buoy] down to the beach... and I had never thought about what really might be underneath [the ocean]... [T]hen I understood the context for them and... became an ocean scientist by the back door. ...Then I had opportunities to go to sea and I continued the research..."

"I've looked at basic bubble physics, and optics... the dynamics of what bubbles do underneath waves, and particularly, sensing them in very difficult conditions like that big storm. ...Acoustical and optical devices for detecting bubbles... just under... [Y]ou're interested in the top meter, but the top meter is going up and down, or in the case by 10 meters. So it's not an easy place to get to. But that kind of challenge, studying bubbles in difficult situations... in the ocean, that's what I do now."

"I was indignant because I hadn't even read about it. ...I was that kid who had read every physics book, every science book, I'd read every copy of ' and whatever else... I was the... kid who had really read everything, and nobody had ever mentioned the ocean."

"Once I understood. Once I looked at the ocean differently... I was cross. Why had no on ever told me about this? Because this is clearly the biggest story on Earth!"
