bubbles in champagne and you can collect starfish this robot is arguably self-aware and the brain that was in that robot was taken out and is now discovering scientific truths and
And they have four legs and a little lure between their eyes. They're Brisingid starfish . They're Pacific and Atlantic.
Human Fish: a squid. Chris: sharks versus starfish ? Bethany: A shark versus anything?
The story in secondary education is also is worse because it costs a lot more money. Ceaselessly picking starfish up one by one throwing them into the sea, the man asked her "Why are you throwing them into the ocean you'll never be able to get them all?"
Greg Sanders: Right, exactly. Jennifer Egan: Called a Starfish . But when I imagined that, it was pre-iPhone. And in a way, I feel like that fantasy's already obsolete because the iPhone is kind of what I imagined. Greg Sanders: Right.
This is a deep-water coral. The red thing on there is a starfish , and that's about 2 feet in diameter. Very little is known about deep-water coral.
And they have four legs and a little lure between their eyes. That's the same type of starfish we saw in the still of the deep-water corals.
Together, we can inspire compassion, stop the violence, and bring about a revolution of love. There are maybe thousands of starfish here.
And he was studying the intertidal zones along the Pacific coast. And he found that this starfish , this apex predator starfish , was a keystone species in the community along the intertidal. Because much like the keystone in a Roman arch, if you removed it-- which he did-- the community collapses.
we actually think it does, it does good for the world which is another way that it feels like it is a right to associate it with the internet where people have that kind of global Brad Bell: If you've ever seen starfish beached and then they die, so he's throwing, one by one, these starfish back into the ocean and the other guy says, "Why are you doing
rules for the way symmetries must interact which enabled him to prove actually that if an object has six symmetries, then either its symmetries behave in the same way of the triangle or the six pointed starfish . So, it enabled him to abstract the idea of symmetry underlying something and this is perfect now when we go to the Alhambra. Because if we look at the tiles on the walls in the Alhambra, how can we say when two of those walls have the same underlying symmetry? Now, they might look geometrically very different but Galois's
So like right now, you could freeze a frame of that and measure everything on the shark precisely. So what looks like worms on there are actually starfish called snake stars. And they have symbiotic relationships with the corals.
degrees, half a turn, so that's three symmetries or I could move all the way around to two thirds of a turn, a fifth symmetry takes me five sixth of a turn around so there are five different symmetries that I can do to this starfish . Now actually there's a sixth symmetry that Galois identified here. This sixth symmetry is just leaving something where it is so that… it's strange. It means everything has one symmetry which is just picking it up and putting it down again. Now, it seems a bit silly but actually this is as powerful as the concept
Together, we can inspire compassion, stop the violence, and bring about a revolution of love. He reaches down. He picks up another starfish and gently tosses him back into the water.
You're seeing them under high magnification here. Common shellfish like clams are calcifiers-- sea urchins, starfish , coral reefs. So lots and lots of marine organisms depend on the process of calcification.
we actually think it does, it does good for the world which is another way that it feels like it is a right to associate it with the internet where people have that kind of global Jane Espenson: Reprogram. Reach every starfish with a computer.
who's getting eaten? Like this is, again, there's lots of exceptions. You can't have nature without things like that. But this is the absolute rule of thumb for how foraging and growth and predation operate across everything from fish to starfish , fish as predators, starfish , praying mantis, all the way up to things like big cats via stuff like crocodiles.
And basically they're going to survive. They only live 500 feet or deeper, and they're relatives of starfish , and they can walk around. And there's a whole bunch of them on a limestone arch.
Together, we can inspire compassion, stop the violence, and bring about a revolution of love. A little boy is at the beach with his grandfather, and there are hundreds of starfish that have washed up along the shore.
The man asked the boy, what he was doing. And the boy replied, I'm throwing these washed up starfish back into the ocean or else they will die through lack of oxygen. But the man said, look, you can't possibly save all of them.
There are problems with runoff and some of these things that are going on. We just recently, at the same time that all of this bleaching was going on, there was a major dieoff of starfish all along the coast here. So these are different things are all part of these impacts that we as people are having in a broad range of ways.
form between the plant kingdom and the animal kingdom. Now, a huge number of organisms fall into this category-- things like corals, which we saw earlier, all those green things, sponges, starfish , sea urchins, earthworms, just to name a couple.
And time and time again, he kept hurling things into the ocean. And as the man approached even closer, he was able to see that the boy was picking up starfish that had being washed on the beach. And one at a time, he was throwing them back into the water.
You can't possibly make a difference. And the boy looked down, frowning, for a moment then bent down to pick up another starfish , smiling as he threw it back into the sea. He replied, now, I made a huge difference to that one.
to far more beautiful creatures we've seen this morning. Just moments before her plunge, Veronica pointed us to a sun star, Heliaster kubiniji, a pink and green starfish in the unmistakable shape of a sunflower. And before that, we all hovered in admiration over the crown sea urchin, Centrostephanus coronatus, which is a sphere of long and slender spines,
we actually think it does, it does good for the world which is another way that it feels like it is a right to associate it with the internet where people have that kind of global I think that, I have this story that I like, it's sort of a parable about starfish and there's two guys walking on the beach and there's one of them throwing starfish back
The story in secondary education is also is worse because it costs a lot more money. "A man walking along the beach one day came over a dune and saw spread as far as the eye could see millions of starfish .
zero? If you're not counting anything, you don't need a number." But the Indians realized the power of zero to actually make advances in mathematics. So, here again this is like the zero symmetry, if you like to think about it. So, there are six symmetries that this starfish has. Let's take the triangle. I can rotate that by a third of a turn clockwise or a third of a turn anti-clockwise and I've got, now I can reflect this as you said. I can reflect in the line through 'x' or I can reflect in the line through 'y' or I can reflect
if I've just reflected in 'z' but now do these in a different order; do the reflection first and then rotate by a third of a turn and it ends up in a different place. It's as if I'd reflected in the line through 'y.' So, the way these symmetries interact enables me to distinguish the symmetries of the triangle from the symmetries of that six pointed starfish . And in fact, Galois developed a sort of set of rules for how the symmetries interact.
