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 20:14:53415304682CC G+

Richard Green19,150Here's my latest Engagers Showcase circle. If you received a notification, that means that you are in the circle.“Showcase” means that you are invited to leave a comment (on the original post) with a link to one of your own posts, which ideally should be one of your best recent posts. This circle consists of people who have engaged with one of my recent posts in the form of +1s, comments and reshares.For reasons of space, I wasn't able to include people whose engagement was limited to +1s on circle shares, and I may have missed other people due to limitations of the G+ interface. I also had no room to include all the engagers on four of my recent non-circle share posts. Because of this, I will be sharing this circle again next week. If you reshare this version of the circle, you are guaranteed a spot in next week's circle. Thanks for reading my posts!2013-07-21 04:25:38464353147251CC G+

Richard Green18,334For my approximately-weekly circle share this week, I've chosen my "Not Just the Usual Suspects" circle. If you received a notification, it means that you are in the circle. As always with my shared circles, this is a "Showcase" circle, which means that you are invited to leave a comment (on the original post) with a link to one of your own posts, which ideally should be one of your best recent posts.Some of the profiles in this circle are people who engaged with recent hit circle shares by +Scott Buehler and +Christine DeGraff, but most of the profiles here are people I selected myself, usually because I liked their profiles for various reasons. As the name of the circle suggests, there are interesting people included here who don't often appear in circle shares.2013-07-14 21:42:0348426892208CC G+

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 19:26:51456348390CC G+
Fraser Cain770,050Super Science Circle - April 2013 EditionIt's time for another sharing of my Super Science Circle.

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.

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 22:39:3139967163160CC G+

"We all have ideas for how to make the world better, but no one ever made the world better by ignoring the scientific facts that inform it. Because as science learns and as better and more fundamental scientific truths are revealed, we increase our understanding of the world and Universe around us, along with the world’s effects on us and our effects on the world.

I want that information, understanding and scientific knowledge incorporated into my society’s policies. And so should you. So should we all."

Don't just imagine a world where politics is informed by science; make it happen. Start by challenging your own preconceptions.

"You see, our Sun is known as a population I star, and it’s very similar to other stars in the plane of our galaxy, and all spiral galaxies for that matter. It’s true that it has even more carbon, nitrogen, oxygen, and silicon than the population II stars, which indicate that there have been even more generations of stars that have lived, burned their fuel, gone supernova, and returned that material to interstellar space before our world was created. But the ratio of the truly heavy elements — from iron to tin to gold and beyond — is inexplicably higher than these ultra-massive stars going supernovae alone can explain."

Where does Earth's gold come from? Surprisingly, the answer isn't from supernovae! Come and find out what it takes to strike cosmic gold.

"We all think of different things when it comes to Earth Day. For some of us, it’s environmental protection, for others, it’s about being thankful for the beauty and bountifulness of nature, for still others, it’s a time to come together and protect our world from manmade woes like nuclear war or climate change.

But for me, when I think of Earth Day, I think of the one thing we all have in common.

I think of our home world. I think of its remarkable story of where it came from in this Universe, about its cosmic insignificance while, simultaneously, how indispensable it is to our own anthropocentric lives. Of the billions of stars that lived-and-died to create the atoms everything in our world is made from, of the biological, chemical and astrophysical accidents that happened to bring about our natural history instead of a different one, and of all the trillions and trillionsof ge... more »

"Whereas our Milky Way has a radius of about 50,000 light-years, the halo of neutral gas surrounding M105 extends for about 650,000 light-years, an incredible distance! Despite being a gas-poor galaxy, there are still more than a billion Suns worth of neutral gas surrounding it, a very large amount.
{...]
Yet perhaps most remarkably, we’ve very recently learned that this galaxy’s gas — much like the neutral gas in most galaxies — is actually collapsing to form not only new stars, but new star clusters as well!"

Elliptical galaxies are supposed to be "dead and red", referring to their old stars formed long ago. So what is this one doing forming new ones today?

"This is, in fact, a process that almost happens in real stars (where carbon+oxygen fusion gets you to silicon-28), but only in the most massive O-and-B-class stars, and only in the last few hundred years of a star’s life. In a real star, two silicon atoms fuse together to get you to iron, but in this game, you can only keep adding helium to silicon to work your way up there!"

What do you get when you combine 1024/2048 and the insides of stars? Fe[26], a super-addictive element-building game!

"Kepler 186 is the name of an M-class star located 490 light-years away, and it has five known planets orbiting it. Kepler 186b is less than 6 million km from its parent star and slightly larger than Earth. Due to its size and proximity, it’s almost certainly tidally locked to its star, with daytime temperature almost double those on the planet Mercury.

But you probably were more interested in Kepler 186f, the potentially habitable one. Lucky for you, I was on TV talking about this just a few days ago!"

From the schools to the stars to string theory, this is a good one!

"4.) Quantum Gravity. The Standard Model makes no effort nor any claims to incorporate the gravitational force/interaction into it. But our current best theory of gravity — General Relativity — makes no sense at extremely large gravitational field or extremely small distances; the singularities it gives us are indicative of physics breaking down. In order to explain what goes on there, it will require a more complete, or quantum, theory of gravity. You might’ve thought, “well, the other three forces are quantized, but maybe gravity doesn’t have to be,” and that would’ve been a reasonable assumption, except for one thing.

The recently released BICEP2 results — assuming the B-mode polarization it detected did, in fact, come from inflation — could not have been generated by primordial gravitational waves unless gravity was a quantum theory! (If you want to havequantum fluctuations stretched ac... more »

"[N]ot only is helium-4 lighter than two protons and two neutrons individually, it’s lighter than four individual protons! It isn’t by all that much — just 0.7% — but with enough reactions, it adds up quickly. In our Sun, for example, somewhere around a whopping 4 × 10^38 protons fuse into helium-4 every second in our Sun; that’s how many it takes to account for the Sun’s energy output.

But it’s not like you can just turn four protons into helium-4; in point of fact, you never get more than two particles colliding at the same time. So how, then, do you build up to helium-4? It might not proceed how you expect!"

"In 1779, there was a comet right in this very region of the sky, and Charles Messier could have found this nebula; he observed it before anyone else. In fact, you may remember that the original purpose of the Messier catalogue was to help skygazers avoid confusing these fixed, deep-sky objects with potential comets, yet that’s exactly what Messier did here! He mistook M61 for a comet, and instead credit for this object’s discovery goes to Barnabus Oriani, who beat Messier to the punch by a mere six days. But 235 years later, it still appears, all but unchanged from how Messier viewed it."

"But when it comes to energy, a factor of 1000 is huge. At energies 1000 times greater than room temperature, it is impossible for electrons to stay bound to atomic nuclei, but at room temperature, the odds of an atom becoming ionized from the 300 K thermal radiation is practically zero. Similarly, at energies 1000 times lower than room temperature, helium loses all viscosity, and becomes a superfluid.

The odds of this happening at room temperature, of course, are also practically zero. Energy effects are exponentially suppressed, so when you have a factor of 1000 difference, your odds of having the thing-you-want happen are suppressed by somewhere around e^(-1000), which is about 1-in-10^430. It’s not impossible, but I think we can safely say it’s very effectively suppressed."

Think about that for a moment.

Yes, 50% were below average. And — although the paper didn’t say one way or another — my assumption is that 50% were above average, as well. Because in almost all samples like this (as a consequence of the central limit theorem), that’s kind of the definition of average. In other words, there was no education or literacy crisis, at least, not based on the actual information that was being used to argue that point."

"From deep inside these clouds of interstellar gas, gravity works to pull every atom in that it can and form more and larger stars. But the stars themselves emit intense, ultraviolet light, evaporating and ionizing the surrounding gas and blowing it out into the interstellar medium.

[...]

So when you look up at the night sky and see those faint nebulae, with their reddish hues from the recombination radiation of hot, UV-ionized hydrogen, you are watching the last stages of that great cosmic star-formation race."

Its central region is quite bright, and in even small telescopes (4", or 10 cm), you can see that it’s brighter in one direction than the other.

And while the Virgo cluster boasts a number of bright galaxies, including 15 Messier objects, it’s a very large structure in reality, located 54 million light-years distant but extending outwards an additional 7-to-10 million light-years in all directions.

It just so happens that Messier 58 is located on the opposite side of the Virgo cluster to us, making it — to the best of our knowledge — the single most distant object in the entire Messier catalogue."

There could have been other, natural explanations for this warming, such as increased solar output, which has been correlated with temperature increases in the past. But, in fact, the opposite has been happening, and the current solar cycle is showing substantially decreased solar activity, which should’ve resulted in a cooling effect, had all other things been equal."

Newtonian gravity’s “failure” to predict the orbit of Uranus led to the discovery of Neptune, while its “failure” to predict the orbit of Mercury gave rise to General Relativity. Similarly, the “failure” of the Michelson-Morley experiment to detect the aether gave way to the Lorentz transformation and, eventually, special relativity. Failure is hardly the right word in its colloquial sense, as these represented huge advances in experimental knowledge, and rigorous tests probing the limits of some of our most cherish theories.

Sounds like a silly idea now, doesn’t it? But it wasn’t a bad idea at all. In fact, it had all the hallmarks of a great scientific idea, because it not only built upon the science that had been established previously, but this idea made new predictions that were testable! Let me explain."

"Yes, it’s true that there are fewer particles as we go to higher and higher energies, but the highest energies are no longer measured in terms of GeVs (Giga-electronVolts, or 10^9 eV), TeVs (Tera-electronVolts, or 10^12 eVs) or even PeVs (Peta-electronVolts, or 10^15 eVs). Instead, these energies can spike all the way up into-and-above the 10^19 eV-range!

Now, this number is really, really interesting, and potentially even limiting! “How’s that,” you ask? Because above about 4-or-5 × 10^19 eV, the Universe won’t let you stay at that energy! The problem, believe it or not, is that no matter how high the energy is of the particle you initially made, it has to pass through the radiation bath that’s left over from the Big Bang in order to reach you."

"So if this result holds up, what does it mean?

It means that not only can we be even more sure that there was a period of cosmic inflation preceding the Big Bang, it means we can begin to tell what kind of inflation we had. It means we can start constructing more accurate and more sophisticated models, and learn how this period of exponential expansion ended, and gave rise to our hot, dense, expanding Universe. It means that Guth, Linde, and probably the principal investigator of the BICEP2 collaboration are in line for Nobel Prizes.

And it means that we should be building LISA — the Laser Interferometer Space Antenna — to detect these waves directly.

"Now, is this a slam-dunk? No. We need much better statistics to announce this as a discovery; we simply cannot take these results to mean “yes there are primordial gravitational waves left over from inflation,” because we need better evidence.

Or rather that general pattern seems to hold, if you forget about elements three, four and five in the periodic table: lithium, beryllium and boron! These three elements are virtually non-existent in the Sun (or any star), and look awfully peculiar when compared to all the elements around them."
