Each segment will be released after the event as a stand-alone YouTube video on the AstrosphereVids channel, thus creating a library of content while raising money for future programs. Planning for this Hangout-a-thon was triggered by the cuts created by sequestration, and by the current White House plans to transition education out of NASA. If the President's current budget is passed, all the funding programs CosmoQuest relies on for will be zeroed (see http://bit.ly/11m5XYg) and the project will be defunded. Rather than accept that fate, CosmoQuest is working to raise the funds needed to keep their programs going, to build new citizen science programs for researchers that don't otherwise have the mThe CosmoQuest 24 Hour Hangout-A-Thon - Main Event Page2013-06-15 18:00:00318

Fraser Cain824,747Super Science Circle for October, 2013I know it's been a while, so it's time for a new Super Science Circle - the October 2013 edition.In case you weren't aware, the Super Science Circle is a list of more than 400 people who are actively engaged on Google+ and regularly post about science and education. We've got journalists, scientists, even a few astronauts. The Super Science Circle should be your best response to anyone who tells you that Google+ is just a ghost town. If you love science, this circle will deliver the goods.If you know anyone who actively posts about science, please let me know and I'll add them to the list.2013-10-04 20:14:53415304682

Then import my Super Science Circle and be amazed at the awesomeness.PLEASE RESHARE THIS CIRCLE... FOR SCIENCE!Every single person in this circle is active on Google+ and regularly contributes high quality posts about science. You've got my personal guarantee.As always, I recommend you import this group into a temporary circle and look for people who match your interests. Then pull them over into more permanent locations in your circles. Or just wait for me to give you an update next month.If you want to be included in this circle, just make a post in the comments and I'll check out your profile.I'm looking for people who:1. Are active on Google+ (but not too active)2. Regularly post about science3. Provide context and additional information, and not just bare links or annoying memes.2013-07-16 18:35:56415255987

Fraser Cain779,548Super Science Circle - May 2013 EditionNeed more science in your Google+? Well, here's all the science you can handle! Enjoy my latest, heavily curated edition of the Super Science Circle.Please share this circle... for Science!For the uninitiated, I maintain a circle of 450+ people who are active on Google+ and regularly post on Google+. In this circle you'll find scientists, journalists, astronauts, educators, and science enthusiasts. By importing this circle into your own circles, you'll immediately gain a vibrant and fascinating feed of amazing science stories.I recognize that it might be too much science, so I suggest you create a brand new temporary circle and evaluate the people in the circle. Only transfer the keepers to your permanent circles. Then, when I update the circle next month, rinse and repeat.Are you active on G+ and regularly post about science? +mention me and I'll check out your profile.Remember, please share this post2013-05-22 19:26:51456348088
Fraser Cain770,050Super Science Circle - April 2013 EditionIt's time for another sharing of my Super Science Circle. This is a collection of 400+ active people on Google+ who often post about science. If anyone tells you G+ is a ghost town (not that anyone does any more), get them to import this circle. PLEASE SHARE THIS CIRCLE... FOR SCIENCE!I have personally reviewed each and every person on this list, to make sure that they:1. Are active and engaged on Google+2. Regularly post science-related stories on Google+In this list you'll find scientists, journalists, researchers, professors, astronauts and general science enthusiasts. Not everyone in this list is going to be to your personal liking. So what you'll want to do is import the list into a temporary circle. Then move people over one by one into more permanent locations in your circles.I'm always looking for more people to add to the list, so if you know people who meet my criteria, feel free to nominate them.Again, please share the circle. Every little bit helps2013-04-26 21:02:03419226277

Fraser Cain759,117The Return of the Super Science CircleOkay, I'll admit, I made a mistake in retiring the Super Science Circle. I wasn't wrong; Communities are still the future and the best way to make friends here on Google+. But I realized that the Super Science Circle is simple and efficient way to get new people to see that Google+ isn't a ghost town.PLEASE SHARE THIS POST... FOR SCIENCE!When I was attending +ScienceOnline 2013, I must have helped dozens of people join Google+, and the first thing I had them do was import this circle. It's an invaluable tool for getting new people up to speed.So, I just did a complete refresh on the circle. I examined every single member and judged them according to my two-part criteria:1. Active in the last 30 days or so.2. Regularly post on scientific topics.If you know anyone who might make a good candidate for this circle, please let me know.As always, import this circle into a new, temporary circle, and then you can refresh it when I share a new version.DON'T FORGET TO SHARE THIS POST2013-03-19 22:39:3139967159161

Fraser Cain694,882The Final Super Science CircleWell, this is it, this is going to be the last posting of the Super Science Circle. Why? Communities, that's why. In case you didn't know, I've been maintaining my Super Science Circle from the very beginning of Google+. As soon as the feature to share circles was enabled, I was happy to share those circles around into Google. I did this because it was very difficult for people with related interests (science) to be able to find each other. I wanted new G+ users to realize this place isn't a ghost town; there are vibrant groups of people actively discussing scientific topics.But it was a hack. Each month took me almost an entire day to curate down the list of people, remove the inactive, and incorporate newly active people who often posted about science. And it was always imperfect. Some people got a massive boost in followers and engagement, while other, equally deserving people were left out.It was inelegant, inefficient and arbitrary.But now you can do this all on your own. You can go into any Community that matches your interest and instantly discover thousands of people who share your enthusiasm for a topic - just joining a Community will bring a trickle of posts about topics that interest you back into your stream. Keep your participation in the Community, or circle the most interesting people and harvest them back into your own stream.In the coming months, I'll be suggesting Communities you should join, instead of people you should circle. Thanks to everyone for using the shared circles and helping science get such a firm foothold here on Google+. Thanks to all the past and present members of the Super Science Circle for sharing such wonderful stuff.Science!2013-01-17 02:59:31420544084
Peter Smalley10,068#sharedpubliccircles   #science  It's been a while since I shared a circle. Let's fix that, shall we? Here is my Circle of Science. Here you will find people who are practicing scientists, science writers, and science enthusiasts - and sometimes all three at once. There are biologists, chemists, physicists, microbiologists, food safety scientists, mathematicians, neurologists, astronomers and many other disciplines represented here. But regardless of their specialties they are intelligent, interested, and interesting.I won't call this a curated circle per se, but I can personally speak to quality of many of these individuals. Many of them are true gems.FOR SCIENCE!2012-11-26 17:29:545015211

Paul Christen41To the person that originally shared this circle with me (I forgot who...)Thank you.I am getting really tired of the glorification of stupid and the vilification of intelligence. I am afraid that its a systemic problem and frankly, I see no end in sight. Its similar to American politics in many ways."Well sure, professional athletes shouldn't rape women, but the dood can throw a football!" "Well, yeah, he ran a dog fighting ring, but let him play football and be a role model to  children anyway."We had a President, that was re-elected, that on any scale was a buffoon at best.The list goes on, and lets not forget the other side  of the  proverbial  coin, how often have we heard politicians talk about the "elite smart people"?Watch an episode or two of "Big Bang Theory". REALLY funny show, I refuse to watch it. I saw two episodes and both portrayed intelligence as negative.I heard an adult say (and I shit you not) "Kids don't need to learn what the mathematical median is, its useless knowledge, average is good enough." I tried to explain how it differs from average and how knowing the average and the median can help get a better view of the data (no point in going too deep) and got "nope, not needed".Whatever, I'm ranting and off the rails here.Do what you need to do to keep YOUR intelligence up and those around you, for the love  of Xenu, fight the good fight. Following this  circle  might help.2012-11-07 13:15:584135110

For Science!If you're interested in my criteria, the circle contains:1. People active on Google+2. People who often post about science.I highly recommend that you import these people into a test circle and then evaluate them over the next month. Move over the people who really delight you to a more permanent circle. Then replace the test circle next month, when I share it again.If you know anyone who should be included in this list, please let me know. #sciencesunday   #evang+  2012-08-20 19:42:04434168405580
Danial Hallock (Kysimir)2,313New Additions to my CirclesA few weeks ago, I added about 50 people to my circles, and it's about that time again.  I added a lot of people from the MSL landing (http://goo.gl/I2yz6), some of my Ninja circlers recommended a bunch of people, and I started adding people whose content made it to my stream via shares on a regular basis.  This is the resulting circle of awesomeness. As usual, they're all predominantly English speaking, engage on a regular basis, and are lacking in the inappropriate labeled NSFW content and hate speech.  :D  Enjoy!If you're notified, you're in it.  Make sure to check out the previous share:  http://goo.gl/chBH4 #circleshare   #sharingiscaring   #awesome   #engagers  2012-08-10 16:37:2848304
Danial Hallock (Kysimir)2,262MSL Circle #2Last night I created a circle of late night people who literally watched history in the making (http://goo.gl/I2yz6).  However, I missed a few of the contributors to the Hang Out On Air with my first circle, and with morning coming a lot more people started dicussing the topic so here is the refresh of last night's circle.If you are notified, you are in it; and this'll probably be my last circle share on the topic, so enjoy!Previoius circle:  http://goo.gl/9QiF0 #msl   #curiosity   #sharingiscaring   #sharedcircles  2012-08-06 14:35:34507214

Fraser Cain125,463Super Science Circle - July 2012 EditionHi everyone, it's time for the July 2012 Edition of my super science circle - and for #sciencesunday . If you're interested in sciency posts from interesting and active people, import this circle and you'll have a delightful stream.Please share this circle... for Science!I've added a handful of people, removed a few, and generally cleaned things up.I'm always looking for more people to add to this circle. People who:1. Are active, posting at least a couple of times a week. But not too active to overwhelm the stream.2. Post regularly about science. Not exclusively, but regularly.If you think you should be in this circle, just post your info in the comments below. As always, I recommend that you import these people into a temporary circle and try them on for size. Only move people to your permanent circles if you want to keep following them. 2012-07-08 20:59:084165476124
Fraser Cain121,559Sharing my Space CircleI'm best known for my Super Science Circle, but I also maintain a circle of people somehow related to space exploration. This consists of scientists, journalists, space agencies, missions, telescopes, amateur astronomers, astrophotographers, and general space fans. I don't require these people to be active posters, so some have never posted on G+, but I'm still including them.If I've left anyone out, please let me know.2012-06-21 02:07:17277771238

Fraser Cain120,480Super Science Circle - June 2012 editionPlease reshare this circle... for Science!Just in time for summer reading, I offer you the latest edition of my Super Science Circle. This list contains almost 400 users of Google+ who are active and post science topics. I have personally evaluated everyone in this list, and made sure they meet my exacting criteria - I think you'll find they're a fantastic addition to any circle collection.As always, I suggest that you import these people into a fresh circle. Then evaluate them for a bit. Move your favorites over to more permanent circles.And I'm always looking for people to add to the list. If you post to Google+ at least a few times a week, and include a lot of science-oriented posts, please let me know and I'll add you for the future.P.S. I was really glad to find that very few people had gone inactive this time around. People are really getting active and engaged - definitely not a ghost town.P.P.S. A big thanks to +Science on Google+: A Public Database for gathering together a large number of science-oriented people. I was able to add about 100 people to my list.2012-06-16 01:22:0239664130109

Indeed, Virgin Galactic is largely a "roller coaster for the rich" -- today. But that's just a step on a path; don't focus on the step, see where the path leads. They're using rich space tourists as a lever to enable access to space for the many. It's the same democratization path that air travel followed.

You want to go to space tomorrow? Then cheer on space tourism today.

"The current designed speed of the rover remains as 200 meters per hour. It can climb a slope of up to 30 degrees, and cross a barricade 350 millimeters high.."

So, this stuff is kinda my bread and butter. Let me discourse on those numbers, and on the design generally.

Slopes

Climbing 30-degree slopes: entirely within the realm of reality. MER's design permitted 45 degrees for the static stability limit (beyond that, we'd flip over and become a turtle), 30 degrees for the dynamic stability limit (where something as innocent as steering your wheels can provoke an uncontrolled slide, and if you're lucky, you don't hit anything bad on the way down). MSL's design numbers are very similar.

Being engineers, we add margin everywhere, so we don't normally traverse slopes above 25-ish degrees (though MER has a record of 31 point... more »

The coolest part of this article is the interactive bit that lets you spin the constellations around to see them from different perspectives. I wonder what creatures on other stars make of Orion -- including creatures on the stars in Orion itself?

Via +Scott Lewis​.com

Our imagination tricks us, but science sets things right

Most, if not all of us, have caught ourselves looking up at the night sky and try to see the "traditional" constellations of our native culture. Connecting the dots into anthropomorphous beings has been something that we humans have done for millenia, perhaps in an attempt to find familiarity in the unknown? 

Though we are biologically wired to find patterns in the chaos, the truth of the matter is that as we gaze up on the celestial sphere, they are not points of light on a surface. Instead, we're seeing the light from stars that are so far apart, that even what we're seeing in the same constellation could be years older than the other!

In this brilliant article by +Summer Ash in +Nautilus Magazine, we're given an amazing perspective of what these familiar constellations would be like if we took a "spin around the block."

This is probably the closest I'll ever get to a selfie with John Cleese (background, wearing hat). And that's fine with me.

He was also kind enough to sign and personalize his autobiography after his talk -- and I made him laugh, just as with Eric Idle! This means I've met three Pythons now (Michael Palin being the third) and have made two of them laugh, which I feel is a darn good record.

You can watch John Cleese's (characteristically hilarious) talk here: Talks at Google: John Cleese

That multi-million-dollar treadmill was put together out of spare parts for $50, and the researcher paid for it out of his own pocket. But to people who care less about facts than they do about stoking the flames of outrage, well, that won't matter much.

"""
A video clip of a shrimp running on a treadmill has somehow become the nation’s poster child for wasteful spending and grounds for the Republican-led House of Representatives science committee to recently investigate wasteful spending of NSF-funded research projects across the country.

My name is David, and I am the marine biologist who put a shrimp on a treadmill—a burden I will forever carry. To be clear, the treadmill did not cost millions of taxpayer dollars, the goal of the research was not to exercise shrimp, and the government did not pay me—or anyone else—to work out shrimp on treadmills.

Now there's a plan for dealing with monopoly ISPs: if they strangle your connection for their own profit, make it lawful to burn down their headquarters. They'll beg for Net Neutrality regulations.

In the 1400s, at the height of the Hanseatic League's power, the Hansa had a simple response to any local lord that barred the passage of river trade: they'd put together an army, burn his castle, and clear the river. They'd then warn the lord not to charge extortionate tolls. The Hansa made a profit, the peasants paid less for their goods, and everyone (save the lord whose castle was burnt) won.

At the time, it was obvious that what was happening was a tariff of some sort. The lord was individually sovereign over a stretch of river, and so had the ability to charge people to cross it. Or seize cargoes. Or charge different trade ships different prices. And once you look at a lord as a governmental entity and not just a private landowner (he was, in actuality, both), it's similarly obvious that what's occurring is a restraint on trade.

But what makes lords special?

Land. Physical territory is unlike every other capital asset, in that it is entirely nonfungible. If your goods are in one place, and they need to be in another, there are a finite number of routes to get from one space to another, to get to market. In addition, there is only one ideal route; the more trade routes plotted into a single space, the more elaborate (and thus costly) they become. This allows the owners of roads, rivers, canals, ports, railroads, and other channels of trade to extract other entities' returns to innovation and trade as rents on land. They can do this through extortion, tariff, legal right, or discriminatory pricing, but every method is essentially identical in its result.

Which is a long way of getting around to Net Neutrality.

Comcast and other telecommunications companies are not "competitors" to the companies that serve over their lines. They're channels of trade, like roads, rails, and rivers. This is more literal than you would expect: if you take a cursory glance at the histories of companies like Sprint and AT&T, you'll find that they descend from entities that once owned a huge number of easement rights -- largely telegraph and railroad easements. There aren't any more of those entities, and the easement rights are rivalrous: just as you can't build a more efficient road to a city that's already wreathed in freeways taking the cheapest routes, you can't lay new cable to compete with Comcast without zigzagging around the places where line is already laid.

This is precisely why common carriage laws exist. This is why they have existed since the 1100s. When allowed discriminatory pricing power, common carriers can free-ride on others' innovation, turning public pain into private profit.  ___Now there's a plan for dealing with monopoly ISPs: if they strangle your connection for their own profit, make it lawful to burn down their headquarters. They'll beg for Net Neutrality regulations.

Holy smoke. Read the whole awful thing. Then reflect that a surveillance regime that would've made the Romanian secret police drool has been installed in America, the UK, and many other countries.

Time seems to come with its own set of rose-tinted glasses. Everywhere in the world, people remember the "good old days" selectively, leading them to dream of restoring a world that never was. In America, that's often a dream of a 1950's that never was; in much of the Eastern Bloc, that's taken the form of nostalgia for Communism.

But every so often, a physical artifact surfaces to remind us of just what those "good old days" were really like. In this case, the artifact in question is a man's Securitate dossier: the author's father spent nearly a third of his life in hellhole prisons, much of it being tortured, for crimes such as "fraudulent crossing of the border." (Which is to say, attempting to escape Romania)

The article here is a fascinating read: it's the author's account of his own life, and how her family was monitored continuously because of her father's dissidence. ("The Securitate had their own keys to our house and ordered us not to pull the curtains in the kitchen to make it easier for them to observe us.")

If you ever wondered just how bad Communism got, this should remind you.

The New York Times has published an unredacted version of the famous “suicide letter” from the FBI to Dr. Martin Luther King, Jr. The letter, recently discovered by historian and professor Beverly Gage, is a disturbing document. But it’s also something that everyone in the United States should read, because it demonstrates exactly what lengths the intelligence community is willing to go to—and what happens when they take the fruits of the surveillance they’ve done and unleash it on a target.

Net Neutrality is a key to having an open Internet. Without it, telecom companies have the power to decide who is and isn't allowed to have a business online. (Hint: if you compete with them, the answer is "no." Hint #2: if your business is successful, expect them to ask you for a "tax" for the answer to be yes. Hint #3: expect that tax to be a significant percentage of your income.) They also get the power to do far more sinister things -- like read and modify the web pages you see in order to insert anything from tracking to ads, or even hijack your traffic outright.

Net Neutrality isn't "Obamacare for the Internet," as Senator Cruz seems to think. It's making sure that a handful of the most unpleasant bastards in the country don't have veto power over your ability to start a business or take your business to whomever you please.

Fortunately, +Matthew Inman has a great explanation of what Net Neutrality actually means.

It's really about crab tacos.

(Incidentally, I was very glad to hear Obama's statement about it earlier today. "Reclassification" is a technical term, but it basically means that cable companies have to treat everyone's traffic the same, and aren't allowed to boost their friends and harm their enemies. It's the regulatory banhammer that the cable companies were being threatened with if they didn't actually regulate their own behavior the way they said they would -- which, in the Netflix incident, they decidedly didn't.)___

"The current designed speed of the rover remains as 200 meters per hour. It can climb a slope of up to 30 degrees, and cross a barricade 350 millimeters high.."

So, this stuff is kinda my bread and butter. Let me discourse on those numbers, and on the design generally.

Slopes

Climbing 30-degree slopes: entirely within the realm of reality. MER's design permitted 45 degrees for the static stability limit (beyond that, we'd flip over and become a turtle), 30 degrees for the dynamic stability limit (where something as innocent as steering your wheels can provoke an uncontrolled slide, and if you're lucky, you don't hit anything bad on the way down). MSL's design numbers are very similar.

Being engineers, we add margin everywhere, so we don't normally traverse slopes above 25-ish degrees (though MER has a record of 31 point... more »

Climbing 30-degree slopes: entirely within the realm of reality. MER's design permitted 45 degrees for the static stability limit (beyond that, we'd flip over and become a turtle), 30 degrees for the dynamic stability limit (where something as innocent as steering your wheels can provoke an uncontrolled slide, and if you're lucky, you don't hit anything bad on the way down). MSL's design numbers are very similar.

Being engineers, we add margin everywhere, so we don't normally traverse slopes above 25-ish degrees (though MER has a record of 31 point something degrees, one time). But we could. Anyway, it's not clear whether they're talking about the static or dynamic limit here, but it's an entirely plausible number either way.

Obstacle Height

Crossing 350mm (i.e., 35cm) obstacles: again, plausible. I don't have a good sense of this thing's scale, but MER and MSL typically take their max obstacle height to be about a wheel diameter. (The real limit is more complex, having to do with the height of the belly and how it articulates as the suspension moves, but that's a good rule of thumb.) MER's wheels are 25cm in diameter; MSL's, 50cm. (Although, again, we apply margin: MER generally avoids obstacles taller than about 20cm.)

So, yes, well inside the ballpark.

Speed

The 200-meter-per-hour number isn't altogether unreasonable, either. Going flat out, MER and MSL can do about 90-120 meters per hour[1] (we almost never actually do that, for a variety of reasons, but the hardware allows it), so their number is within about a factor of two of that.

And on MER and MSL, we traded speed for torque, insane amounts of torque. I haven't looked at the numbers, but I wouldn't be at all surprised if you could back off the torque considerably and still have plenty for climbing obstacles, and then pour the rest into speed instead.

So, pretty believable numbers, all around. The only thing that makes me sad about that 200m/hour number is: they'll break my one-sol distance record (219.66 meters) for sure. :-(

Other Random Observations

Like MER and MSL (and Sojourner before them), this rover has a six-wheeled suspension. But their suspension isn't the rocker-bogie type we've always used. The two front wheels are connected in a bogie arrangement on either side, but the rear wheels appear to be fixed to the body. It's a curious arrangement, one I'd like to hear more about. It seems to me that it's likely to limit their flexibility a bit; compared to our rovers, I expect the suspension will absorb less of the tilt when the vehicle climbs rocks.

(Edit: a couple of people have suggested that the rear wheels aren't fixed to the body, they're connected to each other in a bogie arrangement like the ESA rover seen here: http://is.gd/KmDuEu. That would indeed make more sense and is probably what they've done. I don't know anything about this suspension design, but intuitively, it should be a lot more flexible than the one I pictured.)

I see a very MER/MSL-like antenna arrangement: that lollipop-like thing on the back is a high-gain antenna (medium-speed directional antenna, direct to/from Earth), and it looks like there might be a UHF antenna (high-speed, to/from Mars orbit) just in front of it. If so, that suggests that they plan to send a relay orbiter along with or before this rover, or to arrange to use our or ESA's relay orbiters. And that's sure interesting, either way.

One of those widgets on the front might be a low-gain antenna (low-speed, omnidirectional, good for when you don't know where Earth is because of a software failure or the like) -- though it's a bit short if so.

That little handle-like thing at the very front might shroud cameras meant for imaging the robotic arm's workspace. It doesn't look like those cameras would be able to see the whole workspace, though; that's a long arm, and it looks like it could reach out far enough that those cameras' view of it would be blocked by the shroud. So maybe not. They might still be obstacle-avoidance cameras, though, meant to help the wheels instead of the arm. If so, they plan to use the mast-mounted cameras to image the arm workspace instead, much as MSL typically does.

Speaking of those mast cameras, they're very tall -- this is excellent. If the wheels are ~ 30cm in diameter, as I estimate they are, it looks like they have good stereo separation, too (I mean, between the outermost pair). So it can produce 3-D data out to a long way away from the rover; they'll need that if they want to drive 200m/hour for very long.

(That was always one of my biggest annoyances on MER and MSL, by the way: what limited the distance driven per sol was not the wheel motors but the optics. We just couldn't see well enough, far enough away, to plan super-long drives. If the Chinese have addressed this, their rover drivers are going to be very happy indeed.)

All in all, it seems like a quite decent design. Not revolutionary, maybe, but it's a rover we'd be pretty proud of if it were ours, and they should be proud to do so well right out of the gate.

Just don't try to name it "Spirit," guys. That's taken. :-)

-- 
[1] Actually, now that I think about it, that's still limited by some conservative settings on the motors. I think the hardware is capable of a little more -- truly flat out would be maybe 180m/hour. Which makes 200m/hour even more reasonable.

(Edit: today another, considerably more MER/Yutu-like, prototype was revealed: http://is.gd/Qe3aB3. The relationship between these two prototypes is unclear to me.)___

How lovely to learn that there's a term for that thing I'm so tired of: phatic communication.

Via +Steven Flaeck​.

John Michael Greer on political discourse as phatic communication:

There’s another useful way to speak of the confusion of language in today’s America, and that’s to point out that nearly all our collective discourse has been reduced to phatic communication.  That seemingly exotic phrase describes a very familiar process:  the use of verbal noises to signal belonging and readiness for social interaction.  When two men sit down in a bar here in Cumberland, and one says to the other, “So, how about them Ravens?”—we’re halfway between Baltimore and Pittsburgh, so in football season it’s either that or “How about them Steelers?”—the question needn’t indicate any interest in the team in question.  Rather, it’s a formal way to acknowledge the other person’s presence and claim membership in a community.  In a different context, the question might be “Nice weather, isn’t it?” or some other equally vacant utterance. The form varies but the content—or more precisely the lack of content—remains identical.

Much of today’s political discourse serves exactly the same purpose: it signals readiness for social interaction and claims membership in a specific political subculture, and that’s basically all it does. The verbal noises that get used for phatic communication in that context vary even with fairly small shifts across the political landscape, but if you sit in on a discussion among people who more or less agree with each other’s politics, you can usually figure out pretty quickly what the relevant warm-fuzzy and cold-prickly phrases are, and once you’ve done that you can identify yourself either as a member of the community or as an outsider with a very few words.  It’s an experiment I recommend, partly for the entertainment value, and partly because there are few better ways to learn just how much of what passes for political thought these days is a set of essentially content-free signals meant to define the boundaries of a group.___How lovely to learn that there's a term for that thing I'm so tired of: phatic communication.

Cancer killed my dad. It killed my aunt. It killed my cat. It's killing one of my friends. It tried to kill my stepmom, and it tried to kill me.

I'd like to see a day when nobody has to say things like that. So I'm riding with the Google LA team to raise money for the world-famous Sloan Kettering Cancer Center's fight against rare cancers. (This is a bigger deal than it sounds like: though each such individual type of cancer is rare, when added together, these comprise 50% of all cancer cases.)

I'd like to raise $500. If you want to donate, you can do so at the link below.

Indeed, Virgin Galactic is largely a "roller coaster for the rich" -- today. But that's just a step on a path; don't focus on the step, see where the path leads. They're using rich space tourists as a lever to enable access to space for the many. It's the same democratization path that air travel followed.

You want to go to space tomorrow? Then cheer on space tourism today.

With the passing of Car Talk's Tom Magliozzi, I'll share this memory. Years ago, I was offered the opportunity to call in to the show. I rarely turn these things down, being a self-confessed outreach whore, but in this case, I knew someone who would do a better job with it than I would: my fellow rover driver John Wright. So I handed it over to him, and of course he knocked it out of the park.

Big surprise: Ferguson cops requested an unlawful no-fly zone during the protests specifically to suppress media -- they wanted to keep news helicopters away. The FAA, aware of the unlawful nature of the request, granted it anyway. Just to add insult to injury, the Ferguson cops straight-up lied about it at a news conference.

Do I even need to point out that nobody will be imprisoned or even charged for this crime?

"I think of all the scientists who might have been, but never had the opportunity — especially those who were denied or pressured into studying something else, or not studying at all."

That, in a few words, is one of the major things that bothers me about the absence of women from computer science (and engineering generally, but I tend to focus first on my own field): thinking about how much our world lacks because they're not there. Somewhere out there is -- or was -- a female version of Alan Turing or Donald Knuth or John von Neumann or some such superstar, and the whole world is poorer for her absence and doesn't even know it.

Apple CEO +TIM COOK​ (he's on G+?!) comes out as a gay man. His sexual orientation was pretty much an open secret anyway, but today he makes it official.

His rationale includes helping and inspiring others ("hey, gay teens, we're not kidding about it getting better"). In a way, it's a lot easier for Cook to do this than if, say, he were a gay teen in a rabidly anti-gay Southern family: this won't hurt Apple products in the marketplace, and he surely won't face any personal discrimination over it.

But that hardly means this isn't a great thing to do: on the contrary, it's terrific. It will help kids who are in exactly that situation, trapped in a family and a subculture that hates them for their DNA, and I'm sure it'll help many others as well.

A time before the luxury of antivaccination idiocy:

"""
On April 12, 1955, Dr. Thomas Francis, Jr., of the University of Michigan, the monitor of the test results, "declared the vaccine to be safe and effective." The announcement was made at the University of Michigan, exactly 10 years to the day after the death of President Roosevelt. Five hundred people, including 150 press, radio, and television reporters, filled the room; 16 television and newsreel cameras stood on a long platform at the back; and 54,000 physicians, sitting in movie theaters across the country, watched the broadcast on closed-circuit television. Eli Lilly and Company paid $250,000 to broadcast the event. Americans turned on their radios to hear the details, department stores set up loudspeakers, and judges suspended trials so that everyone in the courtroom could hear. Europeans listened on the Voice of America. Paul Offit writes about the event:

"The presentation was numbing, but the results were clear: the vaccine worked. Inside the auditorium Americans tearfully and joyfully embraced the results. By the time Thomas Francis stepped down from the podium, church bells were ringing across the country, factories were observing moments of silence, synagogues and churches were holding prayer meetings, and parents and teachers were weeping. One shopkeeper painted a sign on his window: Thank you, Dr. Salk. 'It was as if a war had ended', one observer recalled."
