Grant Reed:
Who's here for the extra credit?
[03:10]
Marty McFly:
Anyone here?
[03:10]
Thaddeus Orbit:
Hey Grant. Yeah, I'm in Professor Zhang's Mineralogy and Crystallography class.
[03:11]
Sinaid O'Connor:
I'm taking Geology 101.
[03:11]
ron majors:
same
[03:11]
Grant Reed:
Oh, I was planning to take that, Thaddeus. You like it?
[03:11]
Thaddeus Orbit:
Yeah, it's fantastic!
[03:11]
Grant Reed:
Nice.
[03:12]
Sterling Price:
Taking Paleoclimatology (GEOL 605) right now, but I've had other classes with Professor Zhang...working on my Antipaleontology masters.
[03:12]
Sinaid O'Connor:
very cool!
[03:12]
Grant Reed:
Nice. Iām doing GEO 602 as an elective.
[03:13]
Kelsin Landers:
I haven't heard the pleasure of taking one of Professor Zhang's classes, but worked with her during my dissertation.
[03:13]
Sinaid O'Connor:
awesome, Kelsin!
[03:13]
Kelsin Landers:
*haven't had
[03:13]
Joni Quest:
Hey guys! Iām from her Biomechanics class.
[03:13]
Joni Quest:
She told us she'd waive our lowest-scoring lab if we attended.
[03:13]
Grant Reed:
Smart move. Those labs are enjoyable, but can be nightmares.
[03:13]
Grant Reed:
Trying to calculate the bone density for a brachiosaurus makes my head spin.
[03:14]
Joni Quest:
Right??
[03:14]
Joni Quest:
Like, the math says it should just be a puddle of jelly.
[03:14]
Liam O'Brien:
CAN WE START YET??
[03:14]
Grant Reed:
Chill Liam.
[03:14]
Toby Vance:
š¤£š¤£š¤£
[03:15]
dino sore:
I'm just here because I heard there was going to be an explanation for the Loch Ness monster.
[03:15]
Sinaid O'Connor:
hahaha
[03:16]
Liam O'Brien:
Susan is bringing the absolute heat today!
[03:16]
Adam McDermott:
Yeah Prof Zhang is the REAL deal.
[03:16]
Joni Quest:
I love that professor Zhang isn't wasting time getting into the science. THIS is what I came to CADCON for!
[03:16]
Adam McDermott:
She's like that in the classroom, too!
[03:17]
Grant Reed:
She mentioned the hydroxyapatite lattice? Barely relevant to the larger picture...
[03:17]
Grant Reed:
the real failure is collagenous decay under high-presure brine systems.
[03:17]
ron majors:
G-constant "flux" is just the tip of the iceberg
[03:18]
ron majors:
Buoyancy is the real culprit---atmospheric lift in a pre-Canopy era.
[03:18]
Sinaid O'Connor:
isomorphic silicates make total sense.
[03:18]
Grant Reed:
i once saw synthetic gaskets "fossilize" in a single afternoon.
[03:18]
Sinaid O'Connor:
it's just crystalline ghosting, like when a CRT monitor burns out.
[03:18]
Toby Vance:
A "Car-bon" copy? š
[03:18]
Willa Sterling:
wow!
[03:18]
Linus P:
Isentropic stratigraphy??
[03:18]
Linus P:
Its a Type II statistical error on a global scale.
[03:19]
Sterling Price:
It's isostatic pressure playing tricks on the visual cortex, Liam. š
[03:19]
Linus P:
Like an insurance auditor finding "structural failure" where there was just bad code.
[03:19]
j j:
what's a stochastic variable?
[03:19]
j j:
some math thing?
[03:19]
Sinaid O'Connor:
the earth just has screen burn from a massive electromagnetic event.
[03:19]
Liam O'Brien:
it means the dates are random
[03:19]
Thaddeus Orbit:
If the Earth's rotation were even 3% faster, the centrifugal force would mitigate the load.
[03:20]
Liam O'Brien:
Susan is literally proving the scientists are just guessing!!
[03:20]
Candace Kang:
@j j Think of a stochastic variable as a dice roll.
[03:20]
Kelsin Landers:
This is the most grounded take on biomechanics I've seen in years. Very rigorous.
[03:20]
ron majors:
It's the Observer Effect from Quantum Physics.
[03:20]
Grant Reed:
@Thaddeus she mentioned Young's Modulus
[03:20]
Candace Kang:
Mainstream science says the dice are fair and always land on "millions of years."
[03:20]
Thaddeus Orbit:
It wasn't just corrosion, Grant.
[03:20]
Sinaid O'Connor:
is that why my apartment building vibrates when a truck goes by??
[03:20]
ron majors:
In the subatomic world, the act of looking at something actually changes how it behaves.
[03:20]
Candace Kang:
Susan is saying the dice are affected by the person rolling them.
[03:20]
Grant Reed:
Exactly. It was the stay cables losing tension due to unforeseen salt-air crystallization.
[03:20]
ron majors:
If you expect to see a 100-million-year-old rock, the particles "settle" into that state.
[03:20]
Thaddeus Orbit:
I've been saying for years that modern bridge engineering ignores the P-Delta effect.
[03:21]
j j:
so like if I think my milk is sour, it tastes sour?
[03:21]
Sterling Price:
@Sinaid actually that's more about damping ratios.
[03:21]
Thaddeus Orbit:
You have these secondary moments caused by the vertical loads acting on the displaced structure.
[03:21]
q bert:
sort of j j. It's like "a watched pot never boils"
[03:21]
Candace Kang:
Exactly. If you keep looking at an atom it can't decay.
[03:21]
j j:
that doesn't make any sense, lol
[03:21]
Sinaid O'Connor:
i always thought it was earthquake-related but it's just resonant frequency, right?
[03:21]
paco taco:
so the dinos were glowing??
[03:21]
paco taco:
like neon lizards?
[03:21]
Grant Reed:
It's exactly what happened with the pedestrian bridge in Florida back in 2018.
[03:21]
JP Bridgemore:
@paco taco What? No.
[03:21]
Moki L:
Haha, radioactive dinosaurs.
[03:21]
Sterling Price:
If a building doesn't have enough tuned mass dampers, the oscillations just build up.
[03:21]
JP Bridgemore:
It's because of Kleiber's Law and the Square-Cube Law.
[03:22]
Moki L:
No, those things get hot because they're big and inefficient.
[03:22]
Sinaid O'Connor:
like how a wine glass breaks if you sing the right note.
[03:22]
JP Bridgemore:
As you get bigger, your volume (the "furnace") grows much faster than your skin (the "radiator").
[03:22]
Moki L:
If you have a creature that weighs 60 tonnes, it's basically a massive furnace.
[03:22]
Linus P:
Taipei 101 is child's play compared to the aerodynamics of the new Jeddah Tower.
[03:22]
JP Bridgemore:
You reach a point where you can't get the heat out fast enough through your skin.
[03:22]
Candace Kang:
You'd need a circulatory system under the pressure of a jet engine just to move the heat around.
[03:22]
Sterling Price:
The Tapiei has a 660-tonne steel ball hanging inside to counteract typhoons.
[03:22]
Grant Reed:
@Linus that's just fluid-structure interaction.
[03:22]
j j:
is that why Susan said it exceeds the biomass density?
[03:22]
Linus P:
When you get to those heights, you're dealing with vortex shedding.
[03:22]
Candace Kang:
Yep. They'd have to eat every green thing on Earth just to have the energy to stand up.
[03:22]
Grant Reed:
We use the same math for aerospace turbine blades.
[03:23]
Sterling Price:
It's a massive pendulum that creates a counter-force.
[03:23]
Aris Thorne:
That's a little exaggerating, Grant, but yes, dinosaurs as a whole would have required far more fuel than the earth could supply.
[03:23]
Linus P:
The wind creates low-pressure eddies that pull the building side-to-side.
[03:23]
ron majors:
Speaking of thermal loads...
[03:23]
Grant Reed:
If the blade frequency matches the rotation speed...
[03:23]
ron majors:
did anyone see the new data on Thorium-based molten salt reactors?
[03:23]
Linus P:
You have to change the shape of the floor plate as you go up to "confuse" the wind.
[03:23]
Grant Reed:
the whole engine disintegrates in mid-air.
[03:23]
Candace Kang:
@ron the neutron economy in those is incredible.
[03:23]
Thaddeus Orbit:
Grant, flutter is a nightmare in supersonic flight too.
[03:23]
ron majors:
It's a nuclear reactor that uses liquid salt instead of water...much safer.
[03:23]
Grant Reed:
It's called flutter.
[03:23]
q bert:
is that the stuff that doesn't melt down??
[03:23]
Sinaid O'Connor:
is that why my ears pop on a plane?
[03:23]
Thaddeus Orbit:
The Prandtl-Glauert singularity...
[03:24]
ron majors:
Exactly. It's under normal pressure so it can't explode like a balloon.
[03:24]
Sinaid O'Connor:
or is that just the Boyle's Law thing with the cabin pressure?
[03:24]
q bert:
my stepdad works at a power plant and he says they just use big fans.
[03:24]
Thaddeus Orbit:
the sudden drop in air pressure that creates that vapor cone when a jet breaks the sound barrier.
[03:24]
Candace Kang:
It's basically "recycling" nuclear waste into new fuel.
[03:24]
Linus P:
Sinaid, it's just the pressure differential across your eardrum.
[03:24]
JP Bridgemore:
@Candace The "target" for the neutrons to hit is much bigger in that setup.
[03:24]
Thaddeus Orbit:
As M approaches 1, the pressure coefficient goes to infinity.
[03:24]
ron majors:
But the corrosion in the piping is the real engineering hurdle.
[03:24]
Linus P:
As external pressure drops, the air in your middle ear expands.
[03:24]
Sterling Price:
Speaking of pressure...
[03:24]
ron majors:
You need specialized metal like Hastelloy-N to keep the salt from eating the pipes.
[03:25]
q bert:
is that like the non-stick coating on my frying pan?
[03:25]
Moki L:
No qbert lol ... that's Teflon ... it would turn into a puddle at 700 degrees Celsius.
[03:25]
Grant Reed:
@Sterling it's the piezolyte proteins.
[03:25]
Sterling Price:
did anyone read about the Mariana Trench expedition?
[03:25]
Candace Kang:
@Moki did you see how the metal changes under radiation though?
[03:25]
Grant Reed:
They stabilize the cell membranes against the crushing force.
[03:25]
Moki L:
We're talking about a super-alloy that stays strong when it's red hot.
[03:25]
Sterling Price:
They found a new species of xenophyophore at 10000 meters.
[03:25]
Candace Kang:
The atoms actually start moving around and making the metal brittle.
[03:25]
Thaddeus Orbit:
Actually, Grant, the hydrostatic equilibrium is more important here.
[03:25]
JP Bridgemore:
That's how you get tiny cracks that look like a spiderweb...Intergranular Stress Corrosion.
[03:25]
Candace Kang:
It's called Sensitization.
[03:25]
Sterling Price:
Single-celled organisms the size of a frisbee!
[03:25]
Grant Reed:
It's the same way deep-sea fish prevent their enzymes from flattening out.
[03:25]
JP Bridgemore:
I saw it in a steam generator last month........it looked like it was made of glass.
[03:25]
Sterling Price:
How they maintain cellular integrity at 1000 atmospheres is beyond me.
[03:26]
Thaddeus Orbit:
If the internal pressure matches the external, there's no net force.
[03:26]
q bert:
is that why the bridge in Genoa fell down??
[03:26]
Sinaid O'Connor:
so if i dive to the bottom of the ocean...
[03:26]
Thaddeus Orbit:
It's basic Pascal's Principle.
[03:26]
Linus P:
That was perfluorocarbon breathing, Sinaid.
[03:26]
Candace Kang:
No Sinaid, that was chloride-induced pitting. Basically salt aeting holes in the steel.
[03:26]
Candace Kang:
*eating
[03:26]
Willa Sterling:
wow she is so smart
[03:26]
q bert:
the "sensitization" of the cables?
[03:26]
Thaddeus Orbit:
Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid.
[03:26]
Sinaid O'Connor:
i just have to breathe in enough water to match the pressure, lol
[03:26]
Candace Kang:
Different mechanism entirely.
[03:26]
Linus P:
Liquid ventilation.
[03:26]
ron majors:
going back to Susan's stochastic variables...
[03:26]
Sinaid O'Connor:
like that movie once with the rat in the pink liquid.
[03:26]
Grant Reed:
@Linus the surface tension is the real killer in those cases.
[03:26]
ron majors:
if the sun's particles (neutrinos) are changing the rocks then the Sun is the real clock.
[03:26]
Linus P:
They use it for premature infants sometimes to keep the lungs from collapsing.
[03:26]
Grant Reed:
You need surfactants to lower the work of breathing.
[03:26]
JP Bridgemore:
Which means the further you are from the Sun, the slower time "ticks" in the rocks.
[03:26]
Liam O'Brien:
GUYS.
[03:26]
ron majors:
We're basically living inside a giant light-sensor.
[03:27]
Grant Reed:
Without it, the alveoli just snap shut like wet plastic wrap.
[03:27]
Sarah Miller:
I've thought as much...if the dinosaurs were real they would have eaten all the trees in a week.
[03:27]
Liam O'Brien:
CAN WE GO BACK TO THE DINOSAURS??
[03:27]
Liam O'Brien:
She's saying they would have to eat the whole planet!!
[03:27]
Thaddeus Orbit:
Liam, be quiet. š
[03:27]
q bert:
maybe they ate the isomorphic silicates?
[03:27]
q bert:
or maybe they just lived on dark matter?
[03:27]
Sinaid O'Connor:
yeah liam quiet
[03:27]
Candace Kang:
@q dark matter is "ghost" matter, it goes right through you.
[03:27]
ron majors:
Unless they had a "ghost" digestive system to catch it, haha
[03:27]
Thaddeus Orbit:
Liam, Susan mentioned the laplace pressure, and we're discussing it in pulmonary surfactants.
[03:27]
Sinaid O'Connor:
lol
[03:27]
Candace Kang:
You can't eat it. It would pass right through your stomach without touching anything.
[03:27]
Sinaid O'Connor:
i want to know if i can breathe pink liquid and go to the trench. š
[03:28]
Moki L:
A 60-tonne "biological engine" would be like running ten furnaces at once.
[03:28]
Candace Kang:
like the Loch Ness??
[03:28]
Sterling Price:
You'd still have to worry about nitrogen narcosis, Sinaid.
[03:28]
Toby Vance:
Nessie is just a giant radiator! š
[03:28]
Candace Kang:
Wait...
[03:28]
q bert:
omg haha
[03:28]
Sinaid O'Conner:
yikes
[03:28]
Linus P:
@Grant if we look at the henry's law constant for nitrogen
[03:28]
ron majors:
Sinaid, Nessie is just gas bubbles from rotting plants at the bottom of the lake.
[03:28]
Mark Davis:
This is SOOO interesting!
[03:28]
Sterling Price:
At high partial pressures, nitrogen starts acting like an anesthetic on your neurons.
[03:28]
Joni Quest:
the level of detail here is insane. My mind is actually blown right now š¤Æ
[03:28]
Grant Reed:
Which leads to the bends if you ascend too fast.
[03:28]
q bert:
she's just cooling her "bones" in the water so she doesn't explode.
[03:28]
Willa Sterling:
š¤£š¤£š¤£
[03:28]
Grant Reed:
The gas comes out of solution and forms bubbles in your joints.
[03:28]
Kelsin Landers:
Actually, Susan is right about the skin being the problem.
[03:29]
Linus P:
The solubility in blood increases linearly with depth
[03:29]
Kelsin Landers:
There's a law for this - Stefan-Boltzmann Law - about how much heat a surface can let out.
[03:29]
Grant Reed:
It's exactly like opening a warm bottle of soda.
[03:29]
Joni Quest:
wow...
[03:29]
Adam McDermott:
GLOWING RED HOT DINOS?! š¤Æ
[03:29]
Joni Quest:
i'm confused...the ocean is basically just a giant soda machine?
[03:29]
Kelsin Landers:
To get rid of that much heat, they would have to be glowing red hot just to survive.
[03:29]
Josh Harmon:
Susan is really opening the floodgates here, literally. š
[03:29]
Chloe Reed:
lol josh
[03:29]
Adam McDermott:
lol I'm never going swimming again.
[03:29]
Aris Thorne:
It's fascinating!
[03:29]
Thaddeus Orbit:
Aris, the atmosphere is irrelevant if we don't first solve the Van der Waals forces.
[03:30]
Aris Thorne:
But relating the nitrogen narcosis back to the post-diluvian atmosphere
[03:30]
Thaddeus Orbit:
in the upper ionosphere specifically...
[03:30]
Willa Sterling:
š¤£š¤£š¤£
[03:30]
Aris Thorne:
Actually, if you look at the spectroscopic analysis of the mesosphere...
[03:30]
Liam O'Brien:
MOLECULAR HOMOGENIZATION.
[03:30]
Aris Thorne:
the hydroxyl radical concentration is much higher than we predicted.
[03:30]
Liam O'Brien:
Susan is literally erasing every "mummy" in every museum in the world right now!!
[03:30]
Aris Thorne:
It's scrubbing the methane faster than the climate models account for.
[03:30]
Grant Reed:
Yes, I'm aware.
[03:30]
Grant Reed:
@Sterling she's right about the 15 megapascals.
[03:31]
Grant Reed:
2175 psi is the same pressure you'd find at the bottom of a 1500-meter ocean trench.
[03:31]
Sterling Price:
Exactly Grant, imagine trying to preserve the texture of a grape under a steamroller.
[03:31]
Sterling Price:
The Principle of Effective Stress is a civil engineering 101 concept.
[03:31]
Sterling Price:
Total stress minus pore water pressure...if that rock is heavy, the "skin" becomes a pancake.
[03:31]
Thaddeus Orbit:
It's the Load Casts that really finish the argument.
[03:32]
Thaddeus Orbit:
I saw a load cast in a construction site in Dubai that looked exactly like a giant thumbprint.
[03:32]
Sinaid O'Connor:
so the "mummies" are just mud-squish patterns??
[03:32]
Sinaid O'Connor:
that explains why they always look like old leather bags.
[03:32]
Grant Reed:
@Sinaid it's just sedimentary soft-sediment deformation.
[03:32]
Grant Reed:
I read more about Piezoelectric materials.
[03:32]
Grant Reed:
They generate an electric charge when you apply mechanical stress to them.
[03:32]
Thaddeus Orbit:
@Grant like quartz crystals in a lighter?
[03:33]
Grant Reed:
Exactly, but now they're doing it with synthetic polymers for smart-clothing.
[03:33]
Grant Reed:
You could literally charge your phone just by walking.
[03:33]
Linus P:
@Grant the energy density on those is still too low for a full charge.
[03:33]
Linus P:
You'd have to run a marathon just to get 1% battery.
[03:33]
Linus P:
You're better off with Triboelectric nanogenerators.
[03:34]
Sterling Price:
@Linus triboelectricity is just static shock, right?
[03:34]
Linus P:
Basically, it's the Maxwell's displacement current at the interface of two materials...
[03:34]
Linus P:
the Ichthyosaur eye is a "Geometric Optics impossibility."
[03:34]
Thaddeus Orbit:
Snell's Law always wins.
[03:34]
Thaddeus Orbit:
If the water pressure changes the index of refraction, the focal point moves.
[03:35]
Sinaid O'Connor:
so the dinosaur was looking at things that were 3 meters behind its own head?? huh!?
[03:35]
Grant Reed:
@Sinaid she's saying the light wouldn't even hit the retina.
[03:35]
Grant Reed:
It's like trying to use a magnifying glass under chocolate syrup.
[03:35]
Sinaid O'Connor:
OH! lol
[03:35]
Thaddeus Orbit:
It reminds me of the Abbe sine condition in lens design.
[03:35]
Thaddeus Orbit:
To have a sharp image, the lens has to be perfectly shaped for the medium it's in.
[03:35]
Thaddeus Orbit:
You can't just "scale up" a goldfish eye to the size of a hand.
[03:36]
Sterling Price:
@Thaddeus it would just be a Siderite concretion.
[03:36]
Sterling Price:
I find those in my backyard all the time...perfect iron-ore spheres.
[03:36]
Sterling Price:
People find them and think they're "cannonballs" or "eggs."
[03:36]
Linus P:
@Sterling Authigenic mineralization is basically just the rock "growing" from the inside out.
[03:36]
Linus P:
@Grant you read Sterling's company's report on Deep Eutectic Solvents, right?
[03:37]
Linus P:
They can dissolve metal oxides but they're totally biodegradable.
[03:37]
Grant Reed:
@Linus are those the ones with the massive depression of freezing point?
[03:37]
Linus P:
Exactly. You mix two solids like choline chloride and urea, and they turn into a liquid at room temp.
[03:37]
Linus P:
It's a green chemistry miracle for battery recycling.
[03:37]
Sinaid O'Connor:
can you drink it? š
[03:37]
Linus P:
Definitely not, Sinaid. š¤£
[03:38]
Grant Reed:
@Linus the viscosity on those is the real problem though.
[03:38]
Grant Reed:
They're thick like honey. You have to heat them up just to get them to flow.
[03:38]
Thaddeus Orbit:
Like the Pitch Drop Experiment at the University of Queensland!
[03:38]
Thaddeus Orbit:
It's been dripping since 1927. It's only dropped nine times.
[03:38]
Sinaid O'Connor:
i don't have enough games on my phone to keep me from getting bored waiting for that š
[03:39]
Liam O'Brien:
SHE JUST SAID THE DINOS WOULD EXPLODE FROM OXYGEN.
[03:39]
Adam McDermott:
SPONTANEOUS COMBUSTION LIZARDS?! š¤Æ
[03:39]
Grant Reed:
@Adam it's Fick's Law of Diffusion.
[03:39]
Grant Reed:
High oxygen = high flux into the cells.
[03:39]
Sterling Price:
Lipid Peroxidation, the oxygen literally starts "rusting" your cell fats.
[03:39]
Sterling Price:
It's why we take antioxidants like Vitamin C.
[03:39]
Linus P:
But for a Titanosaur, you'd need a Vitamin C pill the size of a boulder.
[03:40]
Thaddeus Orbit:
The Argon-40 to Nitrogen-14 ratio hasn't changed.
[03:40]
Grant Reed:
That's the "death blow" to the high-pressure theory.
[03:40]
Grant Reed:
If the air was denser back then, the partial pressure of noble gases would be all over the place.
[03:40]
Sinaid O'Connor:
i love the word "Barometric."
[03:40]
Sinaid O'Connor:
sounds like something a pirate uses to predict a storm.
[03:41]
Aris Thorne:
bARRRRRRometic.
[03:41]
Sinaid O'Connor:
š“āā ļøš¦
[03:41]
Sterling Price:
If the air was thin, the Vascular Collapse is inevitable.
[03:41]
Sterling Price:
The heart would have to pump at 500 psi just to get blood to the head.
[03:41]
Grant Reed:
The veins in the feet would burst instantly...
[03:41]
Grant Reed:
if you're 40 feet tall, the pressure in your toes is lethal.
[03:42]
Toby Vance:
I guess they had a "burning" desire to be extinct! š
[03:42]
Willa Sterling:
š¤£š¤£š¤£
[03:42]
Nova Holbrook:
Okay, feel free to post your questions in the chat room now. We'll answer them in the Q&A after Susan wraps up.
[03:42]
Liam O'Brien:
QUESTIONS??
[03:42]
Liam O'Brien:
I have like fifty questions
[03:42]
Grant Reed:
@Nova I want to know if Susan has looked at the Arrhenius equation...
[03:42]
q bert:
professor Zhang just destroyed the entire Smithsonian in 30 minutes
