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 04:25:38464353147248CC 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 21:42:0348426891207CC G+

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 19:26:51456348290CC G+
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.

"Now, I didn’t do that research myself; in fact, no one person did. Scientific knowledge is built person-by-person, observation-by-observation, experiment-by-experiment, and generation-by-generation. Science is both a process — an additive process where all the data ever scrupulously gathered is cumulative — and also a body of knowledge. The most successful scientific theories explain the widest variety of phenomena with the fewest parameters and assumptions. They have the greatest predictive and post-dictive powers, and the largest range of applicability.

And the scientific truths of the Universe, or what we can learn simply by asking the matter and energy around us questions about itself, are truths that are there for everyone to share in."

No matter what your religion is, science is there for us all to enjoy, appreciate and benefit from. This week, it'sthe kindest A... more »

"Somehow, each electron was interfering with itself as it passed through the slits! So this led physicists to the question of how this was happening; after all, if electrons are particles, they should be passing through one slit or the other, just like pebbles or bullets.

So which one was it? They set up a “gate” (where you shine photons to interact with whatever passes through the slit) to find out which slit each electron passed through, and found, sure enough, that it was always one slit or the other. But when they looked at the pattern that emerged, they found the particle pattern, not the wave pattern. In other words, it looked like the electron somehow knows whether you’re looking at it or not!"

"“Lovelace’s paper was quite a shock to everyone,” Caltech physicist John Schwarz, who was then at Princeton,” recalled during a talk in 2000, “since until then nobody considered allowing the dimension of spacetime to be anything but four. We were doing hadron physics, after all, and four was certainly the right answer.”"

Meet the man who brought physics out of our simple 3-space-and-1-time dimensions and into the physically real possibility of many more! Thanks to our new writer Paul Halpern for a great piece!

"You might hear your peers or friends grumble something like, “when am I ever going to use this?” Depending on what you grow up to do, the answer may, in fact, be never. You may never use the things you’re working hard to learn. But there is a very good reason to learn them anyway, and it’s a very simple reason: you need to challenge yourself. You need to learn new things, and you need to force your brain to learn how to solve problems it’s never had to solve before. Imagine two versions of yourself, and the brains inside these two versions: one that only learned things you needed in your adult life, and one that learned as much as you could about as many different things as you could.

"You might hear your peers or friends grumble something like, “when am I ever going to use this?” Depending on what you grow up to do, the answer may, in fact, be never. You may never use the things you’re working hard to learn. But there is a very good reason to learn them anyway, and it’s a very simple reason: you need to challenge yourself. You need to learn new things, and you need to force your brain to learn how to solve problems it’s never had to solve before. Imagine two versions of yourself, and the brains inside these two versions: one that only learned things you needed in your adult life, and one that learned as much as you could about as many different things as you could. Which version, do you think, would have the stronger brain? Would have the better problem-solving skills? Would be better able to tackle the unknown challenges that lie ahead?

I’ll say it once more: learn as much as you can about as many different things as you can. Challenge yourself!"

The best back-to-school advice you can give to an aspiring young student with a talent for math, science, technology or engineering!___

"[I]f we take two galaxy clusters and collide them, and we see the effects of gravitation (from gravitational lensing, in blue) and the aftermath of high-speed gaseous collisions (emitting X-rays, in pink), doesn’t their failure to match up indicate dark matter? Not necessarily; it only tells us that there isn’t enough gaseous dark matter to explain all of the gravitational effects. But you can also see that the optical matter — the collections of stars in galaxies — passed right through one another, the same way that two guns filled with birdshot and fired at one another would have all but very few pellets miss one another."

Even something as convincing as the famed bullet cluster doesn't prove the existence of non-baryonic dark matter; it takes a whole lot more. Yet, we know it's real! Come find out how.

"Each galaxy has a story. Some are small but growing rapidly. Others look bland but betray a complex, vibrant past. What’s more, most large galaxies — again like some cities — appear to be built upon the ruins of smaller, more ancient ones. Our home galaxy, the Milky Way, is not unlike Rome in this respect. Ancient stellar remains show up viscerally in the the faint, extended outer reaches of galaxies — regions of light so diffuse that they’ve been difficult to study until recently."

You've no doubt heard of dark matter halos around galaxies: vast, extended, spherical collection of mass that reach for hundreds of thousands of light-years beyond what we typically think of as a spiral or elliptical galaxy.

"An alternative solution is that Newton’s inverse-square assumption was wrong. Astronomer Simon Newcomb, for example, demonstrated that Mercury’s anomalous precession could be accounted for by “correcting” Newton’s equation to be to the power of 2.0000001574. Most astronomers at the time thought such an idea was unlikely, and later observations of lunar motion showed that Newcomb’s correction didn’t work for the Moon. So a planet Vulcan seemed to be the likely solution.

But it turns out that Newcomb was closer to the truth. When Einstein developed the theory of general relativity, one of the predictions was that Newton’s inverse-square relation wasn’t exact. From this, Einstein was able to show that the Mercury anomaly was due to relativistic corrections."

"In reality, what we’re looking at is a huge globular cluster, some 70 light-years in radius and containing about 1,100,000 times the mass of our Sun inside of it: one of the largest globular clusters in our galaxy! At 29,000 light-years distant, it’s slightly on the other side of the galactic center from us, and its stars are typically about 11.9 billion years old, or nearly three times the age of the Sun."

Globular clusters are almost always perfectly spherical, but this object is very clearly flattened. But is it really oblate like it appears, or is the Universe lying to us? Spoiler for this #MessierMonday: it lies!

"It might seem like a remarkable coincidence, but you must remember that the bigger a black hole is, the less noticeably it’s curved near the event horizon: a counterintuitive notion! If the Earth turned into a black hole and you stood at its event horizon, the tidal forces on you would be more than 10,000,000,000,000,000,000 times greater than the accelerating force due to gravity on Earth’s surface today, but at the event horizon of our galaxy’s supermassive black hole, they’d be only 0.01% as great."

And moreover, when you begin to observe that people behave differently year-to-year or season-to-season, or that people born at one specific time seem to have different traits, what do you attribute it to?"

"What’s even better? The new Fermilab experiment, E989, should be capable of determining the magnitude of the anomaly, if it’s really a deviation from the Standard Model, to somewhere between 7 and 8σ! In other words, while all the world’s eyes have been on the Large Hadron Collider and its search for the Higgs (and potentially, new particles), the first true advance beyond the Standard Model may come from an experiment that few people pay attention to and a small group of theorists that have painstakingly calculated upwards of 12,000 corrections to the muon’s g factor."

Has particle physics taken us beyond the Standard Model at long last? For all you g-2 fans out there!

"Modifying the theory of gravity is no easy game. We have fantastically precise measurements of gravity’s influence on objects throughout our solar system which fit precisely within the current understanding of gravity from General Relativity (a fact that underpins the precision of modern GPS). If you want to change the theory of gravity, you have to preserve its behavior as we’ve already measured it in the solar system."

When you hear about dark matter, you very likely put it up there with string theory in the pantheon of "well, that's a nice idea, now call me when you find it" style of scientific ideas. After all, direct detection of dark matter has proved elusive, despite many arduous experiments designed specifically to find it. Yet we continue to look, convinced that it exists. Why? Amanda Yoho has the top five reasons!

Messier often described stars as “small,” meaning faint, indicating that they appeared small and low-in-brightness in the optics of his own telescope. But these stars are only faint as seen from Earth; in reality, they’re huge and brilliant, even compared to our own Sun!"

"For a long time, we thought this event, estimated to have occurred in 1680, was the Milky Way’s most recent supernova. But remember the following:

-We’re some 25,000 light-years from the galactic center,
-Supernovae occur about once-per-century in galaxies,
-We haven’t seen a supernova since 1604, and
-We were able to find one only 11,000 light-years away that occurred since that 1604 event.

Are there others that occurred since 1680? Up until relatively recently, we would have said “quite possibly,” but we wouldn’t have been sure."

"You might think that this means that the overdense regions will grow unabated, while the underdense regions will shrink, giving up their matter to the denser regions, which are superior at attracting it.

But this intuition greatly oversimplifies things. In reality, when the Universe is dominated by radiation, matter tries to collapse under the force of gravity, but the photon pressure very effectively pushes back outwards with an almost identical force. In reality, the growth is very slow; so long as the radiation density is greater than the matter density, it’s practically negligible. If you have a region of space that starts out 0.001% denser than average — a fairly typical density fluctuation — it won’t become 0.002% denser than average for around 10,000 years, an eternity in the young Universe!"

There was once a time when there were no stars, no galaxies, and no groups or clusters. These all formed, so at some point, the Universe was able to build these structures where there were none before. But today, everything that isn’t already gravitationally bound to itself never will be. How did we go from a perfectly uniform Universe to an almost perfectly uniform one, to one with stars, galaxies, and clusters, to one that won't result in any new gravitationally-bound structures anymore? The physics of gravitational growth (and its end); a fascinating story.___

"It was in fact Heisenberg who first suggested that the divergences in quantum field theory might be cured by the existence of a fundamentally minimal length, and he introduced it by making position operators non-commuting among themselves. Just as the non-commutativity of momentum and position operators leads to an uncertainty principle, the non-commutativity of position operators limits how well distances can be measured."

Yes, it's true that quantum physics from measuring a property such as length or distance to an arbitrary accuracy, but does that necessarily mean that there is a fundamentally "smallest" scale to the Universe? One of physics' great open questions for millennia is still relevant, and Sabine Hossenfelder has a great exploration of it here!

"Traditionally, black holes are detected by using radio waves, but globular clusters are simply too dense and too noisy to have that be a reliable method. Instead, it’s X-rays from gas being accelerated and heated up by the black hole that’s the first signature, which can then be followed-up with high-resolution radio observations to provide confirmation.

The first globular cluster to house a black hole was only discovered in 2007, but that was outside our galaxy. Using that same technique, however, proved incredibly fruitful for Messier 62!"

You need to subject it to intense experimental rigor, and that includes careful controls, reproducibility, and robustly significant results, among other things.

"Scientists are fairly confident that they understand the evolution of the universe right back to the very instants before the big bang. They are also confident that the universe is composed largely of dark matter, whose composition is unknown, and it’s dynamics are dominated by dark energy, which is also not well understood (is it a new force?)

How is it possible to extrapolate back to the big bang, when so little of the matter and force in the universe is understood?"

Given the fact that dark matter and dark energy make up 95% of all the Universe, does that leave any wiggle room for the Big Bang to possibly be wrong? A killer question for this week's Ask Ethan!

But if that's what you think, you've only got it partially right! Tonight and every night for the next week, the Perseids will light up the night sky after sunset. Here's where to find them, where they come from and everything else you wanted to know about meteors, including some surprises you'd never expect!

"“After spending three hours or more in witnessing various experiments, I am not only unable to report a single observation which appeared to indicate the existence of the rays, but left with a very firm conviction that the few experimenters who have obtained positive results, have been in some way deluded.”"

Over 100 years ago, scientists deluded themselves with N-rays, an amazing phenomenon that simply couldn't be consistently replicated. If you've read about NASA's validated 'impossible' space engine, you might notice some eerie similarities. Here's how to avoid fooling yourself in the future!

But unlike the other stars that make up objects in the Messier catalogue, this isn’t a cluster we’re looking at, but a glimpse at one of our galaxy’s spiral arms, seen from our vantage point over 10,000 light-years away!

"Before our Universe was filled with matter, radiation, neutrinos, dark matter or any of the particles that we currently find in it, it was in a rapidly expanding state, where the only energy found in our spacetime was the energy intrinsic to space itself. This was the period of cosmic inflation that gave rise to the Big Bang that we identify with the birth of what we call our Universe. During this time, as far as we can tell, there were quantum fluctuations produced, but they couldn’t interact with one another, as the expansion of space was too rapid to permit interactions mediated “only” at the speed-of-light. As far as we can tell, the expansion was the same everywhere and in all directions, with no particular preferred axis of any type."

"All the matter in the Solar System, all summed together, contains about 10^57 atoms, or 10^29 human-beings-worth of atoms. So an atom, compared to you, is approximately as tiny as you are in comparison to the entire Solar System, combined.

But that’s just for perspective. The 10^28 atoms that are existing-as-you-right-now each have their own story stretching back to the very birth of the Universe. Each one has its own story, and so today I bring you the story of just one atom in the Universe. In isolation, a single atom isn’t so interesting, but as part of your body, right now, I can think of nothing more important."

Here's the story of just one of those atoms, and yet somehow, it's very much the story of all of them.

The first force to be understood was gravity: there's only one type of mass (positive), it's always attractive, and it works the same on everything. The second force was electromagnetism: there are two types of charges (positive and negative), and the charged particles experience forces either in the presence of an electric field or from moving through a magnetic field. And magnetic fields can only be made when you have moving-or-spinning charged particles.

"Opportunity was designed for a 90-day mission and 2.5 million turns of its wheels, powered by its on-board solar panels (during the day) and by its batteries at night. Only time would tell exactly what Opportunity would actually wind up doing.

Well, it’s been nearly 4000 days, around 80 million turns of its wheels, and a lifetime’s worth of discoveries that make Opportunity the most successful planetary science mission of all-time. And it’s still going."

After more than 10 years on the surface of the red planet, the Mars Opportunity rover has finally broken the 41-year-old-record (set on the Moon) for the distance traveled on a world other than our own. But unlike Lunokhod 2, there was no human driving Opportunity; it made its navigation decisions itself! If 1969 was a small step for man, this is one giant leap for robotics and engineers everywhere.

"Do you notice how there’s more lead (Pb) than anything else nearby? That’s got a lot to do with all the heavier elements that we created decaying down in a chain that terminates with lead. So we don’t need protons; we just need the neutron star to break up and then undergo (incredibly rapid) nuclear decays — mostly Beta decay — until it arrives at a quasi-stable configuration. Some of these configurations will be the heavier pre-lead elements in the periodic table (like tungsten, gold, mercury, etc.), while others will be heavier-than-lead elements which will then conventionally decay down to lead. And that’s the story of the heavy elements from neutron stars!"

"But there is one real risk, and it’s a consequence of our physical laws of electromagnetism.

A charged particle is bent as it moves through a magnetic field because of the connection between electricity and magnetism. But that same connection means that a change in electric currents — which are made by the motion of charged particles — create changing magnetic fields. And if you have a changing magnetic field either around a wire or through a loop or coil of wire, you will generate electric currents!

So while there may not be a danger to you, there is a huge danger to electronics, ranging from automobiles to transformers to — most frighteningly of all — the entire power grid! That’s the real danger of a solar storm: an event similar to the 1859 Carrington event could cause anywhere between an estimated $1-to-$2 trillion of property damage, mostly dueto electrical fires."<... more »

But when two neutron stars merge, there’s nothing left to “fuse” at all.

Instead, a few percent of the mass gets ejected as the heaviest atomic nuclei found in the periodic table, but the rest of the two neutron stars merge into a black hole, emitting a gamma-ray burst!"

Like many giant ellipticals, it has a bright (but not point-like) nucleus, surrounded by a much fainter halo of whitish, fuzzy featureless brightness that dims out and fades even farther as you move away from the center. What you’re looking at, unbeknownst to Messier, is a huge galaxy even larger than our Milky Way, more than 50% larger than our galaxy in diameter and more than double the mass.

But while most elliptical galaxies are, well, ellipsoidal, with one long axis and one short axis, Messier 89 appears to be nearly perfectly spherical!"

But is it really fair to call it "elliptical" if it's a practically perfect sphere?

"It shows the color and desolate landscape of the Moon, the long shadows that persist for days, and hints at the impact that human footprints can have for a relatively long time on this airless world.

But my favorite part of this picture is the reflection in Buzz Aldrin’s helmet, which — like all mirrors — shows off a reflection of the half-of-the-world invisible to the photographer.

There he is: Neil Armstrong the photographer, along with the “Eagle” lunar landing module and the rest of the Moon, as far as Buzz Aldrin would have been able to see it.

Today officially marks the 45th anniversary of the Moon landing, so if you can see that waning gibbous in the sky today, make sure you give a wink and think of Neil, Buzz and Michael (Collins, in the orbiter), and what they accomplished all those years ago."

"Dorothy (Bea Arthur) was generally regarded as the smartest and strongest of the four, but also the most reliable and versatile in a crisis. It seems a little silly to say it, but shows like “Sex in the City” and “Girls” would probably have never existed if it weren’t for the Golden Girls.

Well, artist Mike Denison — who it sounds like feels exactly the same way about this show as I do — decided to pay tribute to the witty and acerbic Bea Arthur by creating a new art composition featuring the inimitable lead actress every day for a year, spawning his project “Bea A Day.”"

But will it Bea Art(hur)? Have a look at the "Golden" discovery of the artwork of artist Mike Denison: his "Bea A Day" project!

"Somehow, each electron was interfering with itself as it passed through the slits! So this led physicists to the question of how this was happening; after all, if electrons are particles, they should be passing through one slit or the other, just like pebbles or bullets.

So which one was it? They set up a “gate” (where you shine photons to interact with whatever passes through the slit) to find out which slit each electron passed through, and found, sure enough, that it was always one slit or the other. But when they looked at the pattern that emerged, they found the particle pattern, not the wave pattern. In other words, it looked like the electron somehow knows whether you’re looking at it or not!"

"“The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.” -Neil Armstrong"

Something and someone we should all take time to remember, even those of us who aren't old enough to have been around when it happened.

"One experiment that has instilled both hope as well as controversy among physicists is the DAMA experiment. The DAMA experiment sees an unexplained annual modulation in the event rate at high statistical significance. If the signal was caused by dark matter, we would expect there to be an annual modulation due to our celestial motion around the Sun. The event rate depends on the orientation of the detector relative to our motion and should peak around June 2nd, consistent with the DAMA data."

The first rule of physics is that you must not fool yourself, and you are the easiest person to fool. Finally, a quality explanation that dark matter may not be the key to the DAMA results at all! Thanks to Sabine Hossenfelder for a great post!

"But the discovery of these galaxies also gave us hope that the most glaring small-scale failure of dark matter, the missing mini-galaxies, might actually have a solution. All we’d need to discover, then, would be the theorized tiny dwarf galaxies missing in intergalactic space.

Well, a new type of telescope was recently developed, the Dragonfly Telephoto Array, that uses eight telephoto lenses that can suppress internally scattered light to an unprecedented degree thanks to special coatings on them. This makes them ideal for detecting low-surface-brightness galaxies, the kinds of galaxies we were unable to detect before."

On the largest scales — whether you're looking at the cosmic microwave background, large-scale structure or gravitational lensing — there's no viable alternative to a Universe with dark matter. But on the smallest scales, a number ofpredi... more »

On the largest scales — whether you're looking at the cosmic microwave background, large-scale structure or gravitational lensing — there's no viable alternative to a Universe with dark matter. But on the smallest scales, a number of predictions have gone unrealized for a long time. The worst culprit? The expectation of very small, low-surface-brightness dwarf galaxies as both satellites around larger galaxies and existing in isolation in what's presently identified as intergalactic space. Three years ago, we had nothing, and now we think we've found the first examples of both missing populations. If the Hubble Space Telescope's follow-up observations confirm this, dark matter will rule both the small-scales as well as the large ones!___
