Up next in this #SoCIA18 track is Sheri Wells-Jensen with "Things you didn't see because you were looking: Blind aliens, science and inter- species miscommunication.” I'm not sure what this is about but I'm excited to find out.
Speaker - who is visually impaired, which is relevant given the talk title, and obvious to us here in the room - starts by noting that her introduction name/affiliation/title slide could be full of lies and nobody would notice.
But we have assumptions about this slide starting off a talk. We look for it, and compare against it.
Assumptions: one big one in SETI literature is that aliens will have some analogue to human visual perception.
What would culture be like if blindness was a natural state - no ideas or words about visual perception? What would that do to their culture, and our ability to understand them?
Next chunk of talk: collaborative worldbuilding exercise! What will this species be like? Start in the stone age. No EM-wavelength sensing, no other local species with that talent for them to piggyback on. Other senses and cognition on par with ours. Only vary culture.
Cultural example: she claps to help her determine room size. What if everyone had to do that, more-or-less at once? Would there be some standard Clap Device in modern rooms to enable this process?
Note that these folks don't start with astronomy. They have no evidence of starlight, and very little evidence of moon(s). Thus we have named them "Crickets," per Douglas Adams.
Stone age. Missile weapons are bad, because while you CAN hit a target, prey goes silent once you've taken it out! More snares, or maybe harpoons. Fires restricted to pits. Cooking tools (all tools) are sensing tools.
Iron age. Tactile writing, and identification of materials. Cultural values against lying about physical dangers - you need to be able to rely on each other for "cliff over there" stuff. Smelting as specialized case of cooking.
Science and tech: lots of stuff you can still get just fine. Laws of motion (on/near surface), magnetism (lodestones). Then you can get water/wind power, radio, etc.
Electricity is invisible anyways!
Transportation can certainly do trains. But you don't start identifying that the world is round - you don't notice you have a horizon - until you have radar!
(Apologies: these folks are called Krikkits, not Crickets.)
Turning the radar upward is about when they discover the moon. (They knew SOMETHING caused tides, but not enough evidence that it's a rock overhead.) AAAA A ROCK OVER OUR HEADS WTF.
That's the point where they start worrying about astronomy, hypothesizing that there's reason to send messages to space. And experimenting with radio waves can get them the rest of the EM spectrum.
Pretty neat talk, but it seems like it needs its inverse. I want to think about what the Krikkits make that we don't! Not just which of our things the Krikkits develop (and when/how).
Ah, here it is: she's specifically acknowledging that she doesn't know what extra stuff they have. She needs science fiction talk! Would love to converse with her, but she's off to @scifri!

Handedness comes in two groups, "right handed" and "not right handed." Most people use their right hands for almost all precision movement, but the other group is a broad spectrum from weakly-right to strongly-left. baen.com/handedness
The way we describe and define handedness creates the effect @CStuartHardwick rightly notices. Culture defines how we talk about it - but the behavior is mostly genetic. The % of righties has remained constant across continents and milennia.
Hand dominance is a more squirrelly thing than most people realize. For example, righties are better at *some* things with their left hand... and *some* of these asymmetries flip in lefties. Take a few minutes on #LeftHandersDay to learn more!
But you should read and learn from the #BlackSpecFic report anyways! The missing data is due to idiosyncrasies of the @EAPodcasts model, and has no impact on any other magazine's numbers.
Long story short, we treat reprints very differently from other magazines. For @escapepodcast specifically, they were ~45% of our 2017 stories, and our editorial process has one unified pipeline for originals + reprints together.
Regretting organizing my two Worldcon panels this year. It means I'm not free to throw up my hands in frustration and give up on programming. The last 24hrs have been the last worst icing on a bad cake that's long been baking.
I mean, my panels will be awesome. But if you're skipping programming because you don't trust the con, you've made a sensible choice.
There are always more people who want to be on programming than can fit. There's no way to make everyone happy. I get that. But this weekend's screwups come in the context of a long chain of trust-erosion.
So glad this one came out! "After Midnight at the Zap Stop" by @ouranosaurus is an awesome story - full of late-night grease, and the luckless & the worthy. But also because it's a #neuroscience teaching opportunity. Might even be a #NeuroThursday!
One offhand line explains a technology as "stimulating a particular set of mirror neurons." Which works as a story element just fine. It sounds plausible and authoritative! But as a neuroscientist, I have strong opinions about #mirrorneurons. I don't think they're real.
To be clear, mine is a controversial opinion. Many neuroscientists would disagree. But it's a hill I'm willing to fight on, especially given how often "mirror neurons" crop up in popular science.
This phenomenon - when you look away from a moving thing, and you briefly see illusory motion in the other direction - is the "Motion Aftereffect," and it comes from some very basic brain maneuvers. Who wants to join me on going full #NeuroThursday here? en.wikipedia.org/wiki/Motion_af…
Most neurons in the brain (and elsewhere) do this thing called "adaptation," where they accept whatever's going on as the new normal. For example, if you sit down with your laptop on your lap, you'll soon stop noticing the weight.
This can arise from the crudest single-cell level: some ion channels in the cell membrane have negative feedback loops that self-dampen.
