“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...”
Helen Czerski (born 1978) wikiquote, CC BY-SA 4.0 source
“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.”

“[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.”
Helen Czerski (born 1978) wikiquote, CC BY-SA 4.0 source
“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.”
Helen Czerski (born 1978) wikiquote, CC BY-SA 4.0 source
“They are reducing... drag, which is one of the most complicated problems in , and the penguins just... do it.”
Helen Czerski (born 1978) wikiquote, CC BY-SA 4.0 source
“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...”

“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...”

“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'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.”
Helen Czerski (born 1978) wikiquote, CC BY-SA 4.0 source
“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!”

“I set out to learn. I went around Scripps... I knocked on people's doors and I said "Hello, I'm a physicist. ...I'm learning about the ocean. If you've got a book you would recommend..." and people recommended books to me... [O]ne of them was Jacques Cousteau's Silent World and a whole bunch of others... Once I knew I wanted to learn, I was in exactly the right place to begin that journey.”
