Myth and history

Getting past the nonsense. The reasonable idea that civilizations have in fact existed and then fallen, without notice by modern study. Rocking Like a Hurricane in the B.C. era.

Human history irl

Humanity circa 10,000 years ago. The beginnings of civilization. Early agriculture. Making beer and eventually bread. How not to make bread by putting beer in the oven. More Rocking Like a Hurricane. Just invent pants, beer, and bread and you’re off to a really solid start. “Why are pants, different than shirts?”

The Silurian Hypothesis

The Silurian Hypothesis. Imagining the difference in civilizational detectibility over hundreds of thousands or millions of years. Thinking like ze dolphin. Plastic permanence. Climate impacts written into geology. Radiological evidence.

Proto Indo European

The “Atlantean” conlang. Marc  Okrand and Klingon. Language before language was written down. How we figure out anything about a language from 6500 years ago that is no longer spoken and was never written down.

A review

This was the best worst thing we’ve ever seen. I’m sorry. You’re welcome?

Space tricks

Leaving whole rocket stages to just kinda be in orbit and hit stuff. Talking in space by providing your own atmosphere thanks to your incredible, super lung capacity. Also, how that doesn’t work and Superman needs to be a close talker and hold conversations by vibrating his mouth directly on someone else’s spacesuit helmet.

Superman bodily materials

The hair that can hold at least a half ton. How does Superman cut his hair? Introducing weird gnarly alternate Superman with really long hair and uncut fingernails. Donating Superman’s bits to materials science. Making things out of hair. Totally realistic space elevator musings. Superman as a launch platform. Dissecting the Man of Steel for fun and profit. Using Superman for “free energy” (Saturday Morning Breakfast Cereal).

Super-denuclearization

Superman’s built-in orbital mechanics skills. The tiny bit of nothing that would be all of 1987’s nuclear world arsenal against the power of the sun. The relative tiny-ness of the only nuclear weapons ever used in war. Proposals for nuclear de-proliferation. Going Dr Manhattan on the problem.

A bunch of stuff oh god this movie was silly

Nuclear Man’s totally fab nails. The golden crotch-trim on his super suit. Plugging a volcano. Superman’s “brick vision.” Slowing things down, because the moon has “less gravity.” It’s obvious, really. The actual disasters that await us if Superman pushed the Moon away.

Life and death of a star

A hundred years to uninhabitability is a little bit quicker than we thought. Timelines here to red dwarf and all the unpleasantness in between.

Probing your star

The surprising difficulty of actually reaching the sun. The Parker Solar Probe. Taking a close peek at the corona and the young solar wind. Close as in millions of miles.

Moving Earth

Shifting circumstellar habitability zones. Moving the planet out nearer Jupiter as our sun expands. Throwing moderation to the wind and ditching the solar system. Tidal forces.

Planetary travel in deep space

Relativistic impact vulnerability. Appreciating Earth’s protected position within the heliosphere, blocked from impactors by two gas giants and its own moon.

Earth’s new home

Traveling across deep space with no sun. If you dig deep enough, mayyyyyyybe Kelvin’s “secular cooling” would keep everybody warm for the trip. Signing up for some eye shine. The three-body problem.

Going deep

Living underground. Shielding from the radiation and frigid cold of deep space with kilometers and kilometers of Earth. Learning to eat lots of algae, crickets, and fungus. Taking advantage of geothermal energy at depth. Dealing with Earthquakes while being under some of them. The safety of tunnels.

Space station

Smuggling pickles in your pants into space. And maybe some vodka or cognac. “Who wants a warm pickle?”

* Language & The Expanse w/ Nick Farmer, Linguist
* The Expanse VFX w/ Cailin Munroe
* The Expanse Season 2 (feat Fraser Cain)

Difficulties

The oft-overlooked actual difficulties of space settlement. Not technology and logistics, but like, how hard it will likely be for the humans doing the job at first. And second. And then for a while after, too.

Plants in spaaaaaaaace

Growing fresh food in space habitats. Poop-potatoes. Wide-spectrum LEDs. Self-contained hydroponics/aeroponics.

Low-g situations

People in spaaaaaaaaace. Dealing with microgravity. Bro, do you even lift in space? Eyeball un-squishing. Figuring out how to burp. Fluid-pooling and major injury.

High-g situations.

Turning people into jelly. Differing human sensitivity to sustained g-forces in different directions. The wonderful engineering concept of the ship with omnidirectional seating that reconfigures on-the-fly for optimal g-resistance (The Razorback).

High-speed space impact

Turning into jelly and then having your jelly explode your ship, because physics. Relativistic baseballs. Long-haul space-racing and how to be your own butt-wiping pit crew.

Kinetic weapon diplomacy

Nuclear non-proliferation treaties in space. Orbital kinetic weapons and cloaked nuke-ships playing the role of the submarine as deterrent.

Interstellar highway program

Minimum viable star system bootstrap answering machine. The Fermi paradox. The odds that most of the signs of alien civilization that we might discover would be past.

Man meat

Ahhhhnold! Your average Joe, working construction just like any other regular guy who is a giant bodybuilding monster-person. We really missed this in our coverage of Total Recall 2012.

Memory

Memory “insertion” and memory “deletion” or “blocking” in mouse studies. The great distance from where we are now to trivial memory “vacations” a la Recall. Semantic memory, autobiographical memory, and muscle memory.

Tracking devices

Ideal tracking-implantation locations. The incredible utility of the anus for tracker storage, weighed against the small time window.

Mars

Building Martian settlements with as much radiation exposure as possible: glass! glass everywhere! Radiation exposure on the Martian surface. Burying your dead on Mars: a tasteful resource-wasting mausoleum indoors, a giant pile of bleached-out mummies outside the door, or arrange them in awesome poses?

Space Resources

Natural resources in space. Calculating mining cost vs cost to get it where it will be useful. Mining and transporting Helium-3 for fusion energy. Harvesting oxygen from frozen water and getting rocket fuel as a bonus. NASA’s Moxie and inventing trees for spaaaaace. Making your Martian habitat smell like a dirty fish tank, for science.

Review

Well, we don’t normally do this sorta thing, but oh man this was so good! What the film is about, how it is about, and why it was so special. Appreciating those who do the best work of making history relatable (cough Dan Carlin cough).

Restoration

Film degradation. Scratching, exposure, shrinkage, physical tearing. The crapshoot that is video frame rates in early 20th century film footage. Crank cameras and gearing and compressed-air constant-framerate cameras. Correcting for all of this and the challenge of bringing it all up to a standard 24 fps.

Film is an illusion

The optical illusion that we perceive as movement on a screen. Persistence of vision. Video framerates and the “refresh rate” of the human eye. Motion interpolation as an offense against art and all things good. Tom Cruise fighting the good fight. Motion interpolation as a really neato technology which is actually really cool when not on by default on new televisions. Motion interpolation in VR or video games.

Academic controversy

Historian types and objections to the “enhancements” introduced by the filmmakers. Art vs education and the importance of relatability. Modernizing history. Colorization. 3d-ification. Finding it hard to complain about digital enhancement and remastering which leaves the original materials untouched.

Ion Drive

Compounding acceleration in the relative vacuum of space. Incredible efficiencies versus chemical rockets, and the very low force produced making it only appropriate once spaceborn. The differing problems solved by chemical rockets and ion drives. The benefit of ion drive once out of Earth’s gravity well and going far away. Earth’s tectonic plates, slowly building up to escape velocity. That beautiful blue glow. “Ionic wind” aircraft in-atmosphere: a completely silent aircraft motor with no moving parts!

Landing in spaaaaace

Methods of landing on Mars: Aeroshells, parachutes, rockets, and balloons. Past examples. Different bodies in space and their particular atmospheric densities, atmospheric conditions, and gravitational acceleration.

Nuclear power solutions

Nuclear power vs solar cells. People’s presumption of full-on nuclear reactors rather than the smaller and less-efficient radioisotope thermoelectric generators like on Curiosity. Wondering why we don’t use tiny nuclear robots to blow the dust off of the solar robots. NASA, call us for more great ideas.

Dust storms

Martian dust storms. The low density and force of Martian dust storms, contrary to popular depictions. The visual impressiveness of huge Martian dust storms from space relative to actual effect. The (low) density of the Martian atmosphere and its make-up. How 60mph dust storms are are actually not that powerful: with low gravitational acceleration, static charge, it is very very easy it is to keep dust particles aloft.

Orbital centricity words

The revelation that “geocentric” and “geostationary” apply very specifically to only Earth and there are other words particular to the other major bodies in our solar system. All of the other centricity classifications, including Arecentric for Mars as in the film (though they don’t use it).

Hypoxia

Hypoxia and inability to give detailed instructions to your AI on how to disperse the spirit of humanity into the universe.

Philip K Dick

Giving’em the old Philip K Dick joint. Cyberpunk. Adaptation fidelity.

Even though it looks like it’s the future…

Luminescent tattoos! Bioluminescence, electroluminescence, phosphorescence, and maybe some other -escences too! A world with three boobs. Well, maybe more than that in the whole world. Hand phones. Ubiquitous smart glass. Neck-mounted face-replacing direct-eye laser projectors. Memory manipulation and deletion.

“The Fall”

Digging a hole through the Earth. Trying to find hard things to do when building a space elevator is too easy. Adding unnecessary rockets to your earth-faller to reach a seventeen minute trip time. Digging deep in the Earth and heat issues. Finding impenetrable hot rock stew even without piercing the crust. Atmospheric pressure in the center of the Earth. Making it work by vacuum tube. The one easy straight line through the Earth that avoids the Coriolis effect, and the actually useful curved lines between land areas.

3d space-scanning

Camera rocket grenades that explode into camera bullets. Like a camera, but more messy. IR scanning. Two-dimensional room-mapping by Roomba. Photogrammetry. Playing VR hentai sex games in your room, in your room.
