My next #SoCIA18 talk will be "Being Here: The Significance of Human Place in the Light of Astrobiology," by Sarah Reynolds!
What does "learning about what's out there" teach us about ourselves, here on Earth?
"How are we shaped/influenced by our places of origin and habitation" is not a new question! Just a new context here. Though now we need to distinguish between habitable, habit-worthy, and hospitable. How do qualities of a place & its (native) life relate to position in universe?
Physical and human geography have historically been grounded in astronomically-defined position: position was written in the sky! Measure your position in relationship to time/space coordinate system of stars (celestial sphere).
This also led to astronomical connection to Earth places. Sun's height in sky affects temperature range. Strabo (~64 BCE-22AD) talks about how astronomy, geometry, and heavenly bodies are critical to describe a country's features.
"The phenomena of the heavenly bodies" even affecting personal and political characteristics!
Roger Bacon placed a key role for astrology & geography in his efforts to use science in service of the church. This was oddly progressive: differences between people across the world wasn't about innate differences, but the influences of the local heavens!
The discovery of the New World changed these (European) ideas - affected their notions of what parts of the world were habitable. And Copernican decentering of Earth (as focal point, not superiority) changes context of comparison.
Neat side note: Copernican "enthroning the sun" meant decentering the messy, sloppy, painful Earth. Not at all anti-theological.
Telescope invention made new landscapes visible - and opened tons of debate about what features meant, and what was habitable.
Kepler's ideas included multiple POVs: universal harmonies and the value of shifting vantage points. What seems natural from one view (e.g. Earth's lack of motion) could be obviously untrue from others.
Kant has some weird early speculation, about why we are in the "middle" of variation range around the sun. More interestingly, he noted we don't know what it means to be "terrestrial" b/c we can't separate it - no counterexamples.
So, lots of complex ways in which humans relate to space, and how it affects our understanding of the world. "You Are Here" galaxy images are always wrong - we have no pics of outside of our galaxy! (They're either artistic imagination, or pics of Andromeda.)
Place is important to people. (Forced relocation makes people very angry!) Same idea when it comes to our relationship with the whole planet Earth!

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.
