Joaquin Ferguson0This is a curated circle. It's a circle of people I started following in January, and who have consistently posted something at least once a week during all of February, March, and so far in April, about three months. If you want an interesting stream, you should add this circle. If you're interested in how I curated this circle, and why I think it makes for a really great stream,2014-04-12 08:39:25501301CC G+
Graeme McRae23,459Graeme's January Circle . . . This is a curated circle. It's a circle of people I started following in January, and who have consistently posted something at least once a week during all of February, March, and so far in April, about three months. If you want an interesting stream, you should add this circle. If you're interested in how I curated this circle, and why I think it makes for a really great stream, read on. . .How did these people get in the circle?. . . They must have posted something interesting, at least once, because I don't follow people unless they post something interesting. By now, you're probably not surprised by the number of people on G+ whose pages are full of repeated posts, videos without comments, "what's up" and other uninteresting things. I don't follow those people.How did they stay in the circle since January?. . . After I add someone, I keep them in the circle of people I added around the same time. Then, several times a week, I go through all my circles and delete people who haven't posted (something visible to me) in the last 7 days. So the people who are left in the circle are consistent posters. That says something important about them, because consistency is a proxy for quality.Consistency is a proxy for quality. Why is that?. . . I'll admit it: I don't have the science to back up that wild statement, but I'll tell you why I believe it to be true. People who post crap don't get a lot of followers, and the few followers they have don't bother to engage. After a while, the crappy-posting people start to think G+ is a ghost town, and they lose interest. On the other hand, the people who share (or re-share) interesting things get followers and engagement, slowly at first, but ever increasing, and this outpouring of love is what keeps them going. That's what I think anyway, and I'm sticking to it.People who share interesting things get lots of followers. . . This is another half-baked theory of mine, but hear me out. You might think this makes sense: Google+ offers suggestions of people to follow, especially to new users. Google+'s only source of names to suggest are other G+ers like yourself. The G+ers who have the most engagement are the ones Google+ knows will be good to follow, so these people get put out as suggestions more often, and some percentage of those suggestions are taken up. So the more engagement you have, the more Google+ will sugggest you as a person to follow, and so the more followers you'll get. Completing the theory: the more interesting the stuff you share (or reshare), the more engagement you'll get, and hence the more followers you'll get.How can I get in your circle?. . . Don't bother trying to "get into" this circle. This circle isn't for you to get into. Think of it the other way around. This circle is for you to add, so you can follow a bunch of interesting and consistent people. The stream from this one circle will be chock-full of fascinating content for you to reshare. People will start to notice your reshares, and they will engage with you, and then Google+ will "notice" (it's a computer, but let's anthropomorphise, shall we?) you and suggest you to others, who will then follow you.No, really. How can I get in your circle?. . . First, unfollow me, then wait, oh, about a week. Spend that week posting a shitload of interesting things. Then follow me. Since you're so interesting, Google+ will notify me that you followed me (G+ doesn't notify me about every follower). I'll look at your posts, find one interesting, and follow you. Then, remember to post something every few days. Finally, after two or three months, I might post the circle for the mo2014-04-11 23:47:335009716CC G+

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

Animals and plants are threatened. More than 320 land vertebrates have gone extinct since 1500, the researchers said. The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth. In contrast, the looming sixth mass extinction is linked to human activity, Rodolfo Dirzo, a professor of biology at Stanford University in California, said in a statement. Dirzo is the lead author of the new review of past research on thet... more »

Frisbees are a popular summertime toy, but they involve some amazing physics, too. Two key ingredients to their long flight times are their lift generation and spin. A frisbee in flight behaves very much like a wing, generating lift by flying at an angle of attack. This angle of attack and the curvature of the disk rim cause air to accelerate over the top of the leading edge. Airflow over the top of the disk is faster than that across the bottom;  thus, pressure is lower over the top of the frisbee and lift is generated.

Aerodynamic lift and drag aren’t enough to keep the frisbee aloft long, though. Spin matters, too. If the frisbee is launched without spin, gravity acts on it through its center of mass, but lift and drag act through a point off-center because lift tends to be higher on the front of the disk than the back. This offset between gravitational forces and aerodynamicfo... more »

If the frisbee is launched without spin, gravity acts on it through its center of mass, but lift and drag act through a point off-center because lift tends to be higher on the front of the disk than the back. This offset between gravitational forces and aerodynamic forces creates a torque that tends to flip the frisbee.

By spinning the frisbee, the thrower gives it a high angular momentum acting about its spin axis. Now instead of flipping the disk, the torque caused by the offset forces just tips the angular momentum vector slightly. Physically, this is known as spin stabilization or gyroscopic stability. Tomorrow we’ll take a closer look at airflow over the frisbee.  ( Image credit: A. Leibel and C. Pugh, source video: Frisbee Toy Box Physics ; recommended papers by: V.

In a new and fascinating study of the "Taung Child", scientists argue that cranial development of the Australopithecus africanus had a different and more divergent evolutionary adaptation comparing to Homo's skull than previously thought.

The results have been published online in the journal Proceedings of the National Academy of Sciences (PNAS) on Monday, 25 August 2014."

Supersonic submarine might travel Shanghai-San Francisco in 100 minutes

Chinese scientists are very close to creating a supersonic submarine capable of traveling from Shanghai to San Francisco in less than two hours. Researchers found a way to generate a huge air bubble around the submarine reducing drastically the water friction and therefore augmenting its speed.

This technique is called supercavitation and was developed originally by Soviet military during the Cold War. They built a supersonic torpedo called Shakval that was able to reach 230 mph (370 kmh)—In theory, a supercavitating vessel could reach the speed of sound underwater, or about 3603 mph (5,800km/h.) Chinese researchers solved some of the problems Russian faced with Shakval but not all of them.

Chinese researchers solved some of the problems Russian faced with Shakval but not all of them. South China Morning Post writes: Professor Wang Guoyu, head of the Fluid Mechanics Laboratory at Beijing Institute of Technology who is leading another state-funded research project on supercavitation, said the global research community had been troubled for decades by the lack of innovative ideas to address the huge scientific and engineering challenges. "The size of the bubble is difficult to control, and the vessel is almost impossible to steer," he said. While cruising at high speed during supercavitation, a fin could be snapped off if it touched the water because of the liquid's far greater density.

Single Gene Controls Jet Lag

Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms. The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers or jet lagged travelers adjust to time differences more quickly. The results, published in eLife, can point to treatment strategies for sleep problems caused by a variety of disorders.

Fluorescent oil lets NASA engineers see flow patterns over an experimental aircraft

Researchers at NASA's Langley Research Center in Hampton, Va., use all sorts of tools and techniques to learn more during the development of aircraft and spacecraft designs.

In this photo, engineers led by researcher Greg Gatlin have sprayed fluorescent oil on a 5.8 percent scale model of a futuristic hybrid wing body during tests in the14 by-22-Foot Subsonic Wind Tunnel.

The oil helps researchers "see" the flow patterns when air passes over and around the model. Those patterns are important in determining crucial aircraft characteristics such as lift and drag.

Archimedes proved that the volumes of a sphere and a cone with equal radius and height add up to the volume of a cylinder with the same dimensions. This inspired Rod Bogart to make this charming hourglass.

Algal Blooms and Microcystins: The Fouling of Lake Erie

A Colorful History : Often called blue-green algae, cyanobacteria are neither restricted to blue and green hues nor are they true algae. They bring a carmine tinge to the Red Sea and make the Spirulina-eating African flamingos blush pink. When these simple bacteria appeared 3.5 million years ago, they produced oxygen by photosynthesis, changing the fate of the earth forever. Then in the Precambrian era, according to the theory of endosymbiosis, they were co-opted as chloroplasts into the cells of green plants. They also form nitrogen-fixing nodules in the roots of plants and partner with fungi to colonize barren new lands as lichen. Little wonder that scientists consider them the most successful group of microbes ever. But as Shakespeare mused: Why then, can one desire too much of a good thing?

Algal Blooms and Microcystins: The Fouling of Lake Erie

A Colorful History : Often called blue-green algae, cyanobacteria are neither restricted to blue and green hues nor are they true algae. They bring a carmine tinge to the Red Sea and make the Spirulina-eating African flamingos blush pink. When these simple bacteria appeared 3.5 million years ago, they produced oxygen by photosynthesis, changing the fate of the earth forever. Then in the Precambrian era, according to the theory of endosymbiosis, they were co-opted as chloroplasts into the cells of green plants. They also form nitrogen-fixing nodules in the roots of plants and partner with fungi to colonize barren new lands as lichen. Little wonder that scientists consider them the most successful group of microbes ever. But as Shakespeare mused: Why then, can one desire too much of a good thing?

Toxic Blooms: Ever opportunistic, cyanobacteria can rapidly increase in biomass to form thick green scum euphemistically known as blooms on the surface of shallow lakes. Over-fed with nutrient run-off from fertilized farmlands, sewage disposal or industrial waste, the blooms in turn feed bacteria, which then consume dissolved oxygen, killing off fish and creating dead zones. That’s not all: the blooms produce potent toxins that target the liver, brain and skin. The worst offenders are microcystins: cyclic compounds that fit snugly into the pocket of a class of enzymes known as protein phosphatases (image) and block their tumor-suppressing activity. In 1996, 76 dialysis patients at a clinic in Caruaru, Brazil, died from acute liver failure after water contaminated with microcystins was used in renal dialysis treatment. Their cyclic structure makes microcystins resistant to most water treatment processes, and boiling only concentrates the toxin. The building blocks that make up the toxin are unusual (non-protein amino acids) , and cannot be broken down by enzymes found in our cells. Recently, algal blooms in Lake Erie forced the shut-down of the entire water system in the city of Toledo, leaving half a million residents with no water. Given that this is becoming "the new normal" (http://goo.gl/dPyrtG) in many freshwater supplies around the world, what is the solution?

Bioremediation: There are no short term solutions to the blooming problem! We can cut back on fertilizer use, although faster acting, more efficiently utilized phosphate formulations actually encourage algal growth. Fortunately, we can exploit the chemical warfare in the battleground of the blooms themselves. It's thought that cyanoblooms produce these toxins to protect themselves from heat and oxidation stress. But competing bacteria like Sphingomonas secrete enzymes that can degrade microcystins. Research on natural bioremediation by culturing beneficial bacteria and studying their genetic and biochemical pathways could help nip future blooms in the bud.

A snake’s flicking for taste - no, it’s for 3D smell-o-vision & much more

Most animals with tongues use them for tasting, to clean themselves or others, or to capture or manipulate their prey. A few, including humans, also use them to make sounds. Snakes do not use their tongues for any of these things.

Oscillating tongue-flicks are unique to snakes. They allow snakes to sample 100 times as much air as the simple downward extension of the tongue. The tongue then transfers these molecules to the Jacobson’s Organ via the mouth floor. Evidence suggests that male Copperheads can also find and follow females using oscillating tongue-flicks to detect airborne pheromones, although the details of how they determine direction using such dispersed and transient odors are still poorly understood.

Dale, who was a member of an international task force – dubbed SolarMAX – set up to identify the risks of a solar storm and how its impact could be minimized, explains how it is only a matter of time before an exceptionally violent solar storm is propelled towards Earth. Such a storm would wreak havoc with our communication systems and power supplies, crippling vital services such as transport, sanitation and medicine.

"Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online. Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases we thought we had left behind centuries ago soon returning," Dale writes.

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

Animals and plants are threatened. More than 320 land vertebrates have gone extinct since 1500, the researchers said. The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth. In contrast, the looming sixth mass extinction is linked to human activity, Rodolfo Dirzo, a professor of biology at Stanford University in California, said in a statement.

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

Animals and plants are threatened. More than 320 land vertebrates have gone extinct since 1500, the researchers said. The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth. In contrast, the looming sixth mass extinction is linked to human activity, Rodolfo Dirzo, a professor of biology at Stanford University in California, said in a statement. Dirzo is the lead author of the new review of past research on the topic, which suggests Earth is in the early days of this sixth mass extinction.

A past study, which involved data from the fossil record and modern-day conservation biology, suggested Earth could enter such a mass extinction within the next 300 to 2,000 years. That study was detailed in the March 2, 2011, issue of the journal Nature.

Up to one-third of all vertebrates are threatened or endangered, the researchers said. Large animals - such as elephants, rhinoceroses and polar bears - have the highest rates of decline, which is a trend shared by other mass extinctions. These large animals are at particular risk because they tend to have few offspring and low population growth rates. Hunters and poachers, however, find their fur, meat, tusks or horns attractive targets.

Losing a species of large animal can have unexpected effects on the ecosystem and nearby human developments, a process known as defaunation. In one study, researchers isolated patches of land from animals, including zebra, giraffes and elephants. Without the animals, the grass and shrubs grew tall, and the soil became looser. Rodents quickly took over and doubled in numbers, eating the seeds from the plants and living in the patchy soil that was relatively predator-free.

Rodents can carry diseases and parasites that infect people, the researchers said.

"Where human density is high, you get high rates of defaunation, high incidence of rodents and thus high levels of pathogens, which increases the risks of disease transmission," Dirzo said. "Who would have thought that just defaunation would have all these dramatic consequences? But it can be a vicious circle."

The decline of big animals affects not only vegetation, but also invertebrates. In the past 50 years, the human population has doubled, and the number of invertebrate animals has dropped by 45 percent, the researchers said. Much of the loss is a result of habitat destruction and global climate disruption, the researchers said.

Affecting cognitive decline, negative mass, printing complete boards, atmospheric waveguides, spinning nanorods, restoring insulin sensitivity, wave tractor beams, biomimicry for audio chips, solar passive cooling.

1. A (Reversible?) Mechanism for Age-Related Cognitive Decline.
Recent studies show that extracellular matrix proteins in the hippocampus of animals undergo robust and progressive upregulation over time, increasing with age and believed to directly contribute to cognitive decline by inhibiting synaptic plasticity and cell mobility https://www.fightaging.org/archives/2014/07/involvement-of-the-extracellular-matrix-in-age-related-memory-loss-in-mice.php. The studies were conducted in mice and so confirming the effect in human brains will be important. Given that only one group of four proteins of the extracellular matrix increased strongly, this may present a convenient target to down-regulate protein expression and restore cognitive function. Speaking of cognitive decline a non-invasive retinal imaging technique claims to detect changes indicating Alzheimer’s 15 to 20 years before clinical diagnosis http://www.cedars-sinai.edu/About-Us/News/News-Releases-2014/Study-of-Noninvasive-Retinal-Imaging-Device-Presented-at-Alzheimers-Conference.aspx. 

2. Proving Negative Mass can Exist in the Universe.
The consensus in cosmology has been that negative mass cannot exist in the Universe due to theoretical conflict with things like General Relativity. However, recent analysis and new solutions to General Relativity imply that negative mass could indeed exist in our Universe without conflicting existing theories https://medium.com/the-physics-arxiv-blog/cosmologists-prove-negative-mass-can-exist-in-our-universe-250a980320a7. Turns out that if negative mass exists it would create a plasma in space that would absorb gravity waves, and so providing a plausible answer for why gravity waves have never been detected despite increasingly sensitive instruments. Whether there is a threshold frequency above which gravity waves might propagate through such a plasma is an interesting avenue of inquiry that might provide an interesting means to test the theory. A minority of cosmologists postulate that antimatter has negative mass but there has not yet been an empirical test one way or the other http://en.wikipedia.org/wiki/Gravitational_interaction_of_antimatter. 

3. All-In-One Printer for Functional Circuit Boards.
Representing another little evolution in the technology for printable electronics, the Squink printer takes your designs for a circuit board, prints traces with conductive ink, prints conductive glue where the components will attach, and then finally engages a pick-n-place robotic tool to place the components - such as resistors, diodes, ICs, etc - where they are supposed to go http://gizmodo.com/this-all-in-one-printer-churns-out-completely-functiona-1608373786. Once the wet-phase material has cured and dried the printed board can be fired up and used; great little advance for hobby and prototyping applications with commensurate cost and time savings. Should get more sophisticated over time too.

4. Punching Laser Waveguides in Air.
Short, powerful laser pulses can now be used to create the equivalent of optical waveguides in air, the core of which has a higher refractive index than the outside, and so allowing concentrated focusing of subsequent laser light - avoiding the typical spreading and loss of intensity with distance that light in air experiences http://cmns.umd.edu/news-events/features/2356. The laser pulses last only a trillionth of a second, but the “fibers” or waveguides formed last for milliseconds; a very long time in comparison and longer than needed to take advantage of by firing more powerful beams down the guide with little or minimal loss of energy. While longer distances still need to be tested but there are very promising applications in high-bandwidth air-based communications, long-range chemical analysis, over-air power transmission, and laser weapons to name a few. 

5. Rapidly Spinning Nanorods for Chemistry and Medicine.
Nanorods injected into the bloodstream of mice and rapidly spun up by magnets have been shown to double the effectiveness of blood-clot busting drugs that help with stroke; the rods act like a mixing tool, shaking the clots and helping the drug be more effective and ideally allowing a much lower dose (and lower side effects) to achieve the same therapeutic result http://spectrum.ieee.org/nanoclast/biomedical/devices/nanoparticles-improve-stroke-treatment/. Further, nanorods measuring 300nm by 2000nm, placed in solution will rotate at 150,000 rpm when stimulated by 3MHz ultrasound, and act as a very effective and dispersed mixing mechanism with possible applications in speeding up chemical reactions http://phys.org/news/2014-07-ultrasonically-propelled-nanorods-dizzyingly-fast.html. 

6. Injecting a Single Protein Restores Insulin Sensitivity and Normal Glucose Metabolism.
Injecting the protein FGF1 (fibroblast growth factor) into mice with type 2 diabetes results in the restoration of normal insulin sensitivity and glucose metabolism for up to two days; sustained treatment could possibly cure type 2 diabetes in humans http://www.salk.edu/news/pressrelease_details.php?press_id=2037. The molecule does all of this without causing the normal side effects and other risks associated with most other diabetes drugs. While promising this is still early stage; to progress to humans the group wants to discover the biochemical pathway that causes the effect, and will also need to create modified proteins that stimulate insulin sensitivity without stimulating cell growth (which this one does).

7. Creating Tractor Beams with Waves.
It has previously been demonstrated that laser light can exert both a pushing and a pulling force on objects. Interestingly, these concepts have now been scaled up and applied to conventional water waves, in which the propagation and timing of water waves can either push or pull floating objects https://medium.com/the-physics-arxiv-blog/tractor-beam-created-using-water-waves-8d9271134c50. That’s a backward pulling force from forward propagating waves, and a pretty interesting fluid dynamics result. Applications could include feeding the knowledge back into the laser work for better optical tractors, better tracking of ocean-borne ships, rubbish, and debris, more efficient cleanup of oil spills, and fun applications with wave pools. 

8. Biomimicry Inspires Super Acoustic Chips.
Drawing on inspiration of a certain fly’s auditory apparatus - which it uses to precisely target crickets on which to birth its larvae - a chip-based replica has been engineered that uses a similarly-structured 3mm square mechanical beam on silicon with a piezoelectric coating that is able to very accurately sense displacement modes corresponding to sound direction and distance http://spectrum.ieee.org/tech-talk/at-work/test-and-measurement/mimicking-the-super-hearing-of-a-crickethunting-fly. Such a miniaturised chip-based acoustic sensor has military applications in sensing the direction and distance of sound sources, but it might also help improve this indoor positioning system based on echolocation http://www.technologyreview.com/view/529176/an-indoor-positioning-system-based-on-echolocation/, or even allow simple devices such as mesh networked sensors to cheaply and easily determine the direction and distance to other devices. 

9. Engineering Passive Cooling into Solar Cells.
As good as current solar panels have become they suffer significant losses in energy conversion efficiency when they become too hot and proposals to install active cooling systems almost defeat the point due to the energy required by the pumps. A new passive cooling system involves applying a thin layer with a pattern of micropyramids onto the panels that are optimised to draw away heat and shed it into the atmosphere as infrared radiation http://www.gizmag.com/self-cooling-solar-cells/33061/. The coating lets visible light in and and infrared light out, and should lower operational temperatures, increase efficiency, and lengthen operational lifetimes. 

10. Project Loon Matures After One Year.
Twelve months after first being announced Google’s Project Loon has started to mature, achieving new and significant milestones with its high-altitude balloons designed to provide wireless, ground-level Internet access http://www.wired.co.uk/news/archive/2014-06/17/google-loon-one-year-on. Now considered to be more likely than not to be a viable commercial operation in future, the balloons are providing up to ten times the bandwidth, navigational abilities, and flight times compared to one year ago. A year ago the balloons remained aloft for a few days; now an average of 75 days is common and many pass 100 days with some circling the globe three times. LTE communications have been added and download speeds reach up to 22 MB/s compared to 2 MB/s. One step closer to seamless global wireless Internet access.

Ward's "traffic light" reaction

A solution of glucose, sodium hydroxide, and indigo carmine, when shaken, will change from yellow to red to green. Left to sit, it will revert to red again, then yellow, and the process can be repeated. The indigo carmine is green when oxidized, yellow when reduced, and red in the intermediate semiquinone state.

Baby Pygmy Seahorses Are Even Cuter Than You Think

"Every morning, the male and female do 30-60 minutes of synchronized twitching." :D

These are Bargibant’s pygmy sea horses, and their orange, studded bodies twitch and sway just like the piece of coral they’ve wrapped their tiny, tiny tails around.

“Mathematistan” by Martin Kuppe

This detailed map of the landscape of mathematics was designed by Martin Kuppe as part of his recent YouTube video Mathematics: Measuring times laziness squared. As well as being humorous, the picture also illustrates the relationships between the major areas of mathematics, such as algebra, geometry, topology, and analysis. The picture is very detailed and is worth viewing at high resolution.

The video, which you can see at http://goo.gl/3Rg8jd, is well worth twenty minutes of your time. It gives an overview of mathematics in a way that should be comprehensible to an intelligent general audience. The sense of humour in the videos reminded me of the writing of Douglas Adams. Something I found especially remarkable is that the video manages to explain the gist of what algebraic topology is in a few minutes, without getting technical.(Al... more »

Something I found especially remarkable is that the video manages to explain the gist of what algebraic topology is in a few minutes, without getting technical. (Algebraic topology aims to understand topological structures by associating algebraic objects to them.)

The map contains various visual and verbal jokes about mathematics; some of these are explained in the video, but others are not. I liked the names of the plains: have a look for the Complex Plain, the Projective Plain and the xy-Plain. The buildings in Statistigrad look like normal distributions and histograms. The fields in the picture are actual fields, but this is a reference to the algebraic notion of a field, which roughly speaking is a structure in which one can do addition, subtraction, multiplication and division. (This is not directly related to the use of the term field in physics.)

As an algebraist, I particularly enjoyed the Califate of Al-Gebra, with the Al separated as if it were an Arabic article. This is appropriate because the English word algebra comes from the Arabic term al-jebr, meaning “reunion of broken parts”. In case you're wondering, califate is an acceptable variant spelling of caliphate.

I was very surprised that Martin Kuppe/Zogg doesn't have a much bigger following on social media, given the high quality of his output. You can follow him as ZoggFromBetelgeuse on YouTube, or as ZoggTheAlien on Twitter. One of his recent tweets contains links to various versions of Mathematistan, including this picture.

Spectroscopy and the Birth of Astrophysics

The 3D animation depicts how the light of a distant star is studied by astronomers. The spectrum of the light provides vital information about the composition and history of stars. Now, a brief history of stellar spectroscopy.

In 1802, William Wollaston noted that the spectrum of sunlight did not appear to be a continuous band of colors, but rather had a series of dark lines superimposed on it. Wollaston attributed the lines to natural boundaries between colors. Joseph Fraunhofer made a more careful set of observations of the solar spectrum in 1814 and found some 600 dark lines, and he specifically measured the wavelength of 324 of them. Many of the Fraunhofer lines in the solar spectrum retain the notations he created to designate them.

Spectroscopy and the Birth of Astrophysics

The 3D animation depicts how the light of a distant star is studied by astronomers. The spectrum of the light provides vital information about the composition and history of stars. Now, a brief history of stellar spectroscopy.

In 1802, William Wollaston noted that the spectrum of sunlight did not appear to be a continuous band of colors, but rather had a series of dark lines superimposed on it. Wollaston attributed the lines to natural boundaries between colors. Joseph Fraunhofer made a more careful set of observations of the solar spectrum in 1814 and found some 600 dark lines, and he specifically measured the wavelength of 324 of them. Many of the Fraunhofer lines in the solar spectrum retain the notations he created to designate them. In 1864, Sir William Huggins matched some of these dark lines in spectra from other stars with terrestrial substances, demonstrating that stars are made of the same materials of everyday material rather than exotic substances. This paved the way for modern spectroscopy.

Since even before the discovery of spectra, scientists had tried to find ways to categorize stars. By observing spectra, astronomers realized that large numbers of stars exhibit a small number of distinct patterns in their spectral lines. Classification by spectral features quickly proved to be a powerful tool for understanding stars.

The current spectral classification scheme was developed at Harvard Observatory in the early 20th century. Work was begun by Henry Draper who photographed the first spectrum of Vega in 1872. After his death, his wife donated the equipment and a sum of money to the Observatory to continue his work. The bulk of the classification work was done by Annie Jump Cannon from 1918 to 1924. The original scheme used capital letters running alphabetically, but subsequent revisions have reduced this as stellar evolution and typing has become better understood.

While the differences in spectra might seem to indicate different chemical compositions, in almost all instances, it actually reflects different surface temperatures. With some exceptions (e.g. the R, N, and S stellar types), material on the surface of stars is “primitive”: there is no significant chemical or nuclear processing of the gaseous outer envelope of a star once it has formed. Fusion at the core of the star results in fundamental compositional changes, but material does not generally mix between the visible surface of the star and its core. Ordered from highest temperature to lowest, the seven main stellar types are O, B, A, F, G, K, and M. Astronomers use one of several mnemonics to remember the order of the classification scheme. O, B, and A type stars are often referred to as early spectral types, while cool stars (G, K, and M) are known as late type stars.

Scientists assumed that the spectral classes represented a sequence of decreasing surface temperatures of the stars, but no one was able to demonstrate this quantitatively. Cecilia Payne, who studied the new science of quantum physics, knew that the pattern of features in the spectrum of any atom was determined by the configuration of its electrons. She showed that Cannon’s ordering of the stellar spectral classes was indeed a sequence of decreasing temperatures and she was able to calculate the temperatures.

Still Exerting a Hold on Science

This year’s top gravity prize of $4,000 went to Lawrence Krauss and Frank Wilczek. Dr. Wilczek shared a Nobel Prize in 2004 for his part in developing the theory of the strong nuclear force, the one that holds quarks together and forms the cores of atoms.

So far gravitons have eluded science’s best detectors, like LIGO, the Laser Interferometer Gravitational-Wave Observatory. Dr. Dyson suggested at a recent talk that the search might be futile, requiring an instrument with mirrors so massive that they would collapse to form a black hole — gravity defeating its own understanding. But in their paper Dr. Krauss and Dr. Wilczek suggest how gravitons might leave their mark on cosmic background radiation, the afterglow of the Big Bang.
