Magnetic Reversal

The magnetic field of the Earth is often portrayed as a large magnet that runs through the center of the Earth, with the magnetic poles located basically at the north and south poles of the Earth, but this is only a rough approximation. Earth’s magnetic field is generated in its core. The core of the Earth has a solid central region surrounded by a fluid outer region. This outer region undergoes convection, and its motion generates the magnetic field through what is known as a dynamo effect.

This is similar to the way the Sun’s magnetic field is generated. For this reason, the Earth’s magnetic field (like the Sun’s) is not static. Over the past several centuries, for example, we have seen the magnetic field gradually change, and can even observe how the location of the north and south poles shifts over time.

We know that the Earth’s magnetic field has undergone reversals through geological evidence. For example, the mid-atlantic ridge is a boundary between tectonic plates that are gradually pulling about at a rate of a few centimeters per year. As they pull apart, magma flows through the fissure to create new ocean floor. When the magma solidifies, its magnetic alignment with the Earth’s magnetic field is lock in stone. By measuring the magnetic field of the ocean floor near the ridge, we can observe how the orientation of the Earth’s magnetic field has changed over time.

What we find is that over the past 20 million years Earth’s magnetic field has reversed every 200,000 – 300,000 years or so. Because we can observe the changes over time, we also know that these reversals typically happen gradually, over thousands of years. We also know that the Earth’s magnetic field doesn’t completely disappear during a reversal. Instead it becomes chaotic during the transition period before settling down again.

Because the Earth’s magnetic field provides protection against solar flares and the like, it has been suggested that a magnetic reversal could lead to catastrophic changes in the Earth’s ecosystem. But studies comparing magnetic reversals with things like extinction events have found no evidence of the reversals affecting life on Earth in any significant way. There are species that depend upon Earth’s magnetic field, such as migrations of birds, and these could be seriously impacted by a rapid change in our magnetic field, but these effects would be localized, and not catastrophic.

So there’s no need to fear a magnetic reversal. Earth’s magnetic field has undergone a reversal fairly frequently on a geological scale, but such reversals don’t pose a threat to life on Earth. Long term it just means we’d need to switch the labels on our compasses.

Wildfire Burns in the Bodie Hills
I saw a fire burning in the Bodie Hills on Friday July 18, which apparently had been ignited by lightning the day before.  Air tankers were dropping fire retardant on the fire until it got too dark for them to continue.  There were quite a few fire trucks along Bodie Road Saturday evening as I drove to my night photography workshop at Bodie, but the rain on Saturday seemed to knock it down significantly, so by mid-day Sunday only two trucks were remaining to see if it flared back up.

Mansion of Wind and Waves

Last night Lisa and I ate at Feng Bo Zhuang on Temple Street in Singapore.  We went there since it had good spicy food from Hunan and Dongbei, a crowd of happy customers, and nice wood decor... but it turned out to have a jiang-hu theme: that's what Chinese call the world of wandering martial artists and swordsmen. 

See that sword on the wall there?

The name of this restaurant means 'Mansion of Wind and Waves' - but 'wind and waves' means the turbulence and fighting that that goes on in the jiang-hu.  There's a poem by the entrance that says "in the jiang-hu you have no choice, you either fight back or die".  This tough world is romanticized in wuxia fiction and movies:

Typically, the heroes in wuxia fiction do not serve a lord, wield military power or belong to the aristocratic class. They are often from the lower social classes of ancient Chinese society. Wuxia heroes are usually bound by a code of chivalry that requires them to right wrongs, fight for righteousness, remove an oppressor, redress wrongs and bring retribution for past misdeeds. The Chinese wuxia traditions can be compared to martial codes from other countries, such as the Japanese samurai's bushido tradition, the chivalry of medieval European knights and the gunslingers of America's Westerns.

We had frog cooked in bamboo, dumplings with hot broth inside called xiaolongbao, spicy sliced cucumber, and an appetizer of roast peanuts.  Very tasty with some Harbin beer!

Back in 2011 this restaurant was quite serious about the jiang-hu theme: the waitresses would wear traditional outfits and chant a poem when you left.  When one reviewer tried to pay by credit card, his waitress said “江湖中只收银两” - "in jiang-hu, we only accept silver ingots".    Luckily it's mellowed out by now; none of this nonsense, just good food.

As usual, most of my expertise on Chinese culture comes from Lisa... but the long quote is from here:

https://en.wikipedia.org/wiki/Wuxia

and the 2011 review is here:

Don't kid yourself

The problem with Hamas is that they make use of human shields specifically to hurt Israel politically.  The more dead kids, the happier they are because it makes Israel look bad.  It's a form of relishing indirect misery not unlike those with some distant connection to holocaust survivors. 

We're all the same, we're all equally flawed.  The only differences between us are environmental. We are all our lowest common denominators, whether we admit to ourselves or not. 

The problem is that we try to separate ourselves from the baby killers and those that put the babies in harm's way to be killed. They're just us in a different set of circumstances.  We're not smart enough as a species to recognize this because we fear that this realization will mean we cannot justify the exacting of revenge, or that somehow diminishing this threat of revenge will lead to a chaos we're not already experiencing.

Dear Supreme Court:

Among other interesting consequences of the Hobby Lobby decision, you've just given every single person in the country effective line-item veto power over most laws: any person or "closely-held corporation" can invoke strict scrutiny on anything by simply saying "I don't wanna." (Or rather, "this violates my deeply-held religious beliefs," but go ahead and try to define that one as anything stronger than "I don't wanna." Half the Christian denominations would burn you at the stake.)

You asked for it, you got it.

Fist Bumps Pass Along Fewer Germs Than Handshakes

"A few weeks ago, we took a look at nonverbal greetings around the world. In Japan, they bow. Ethiopian men touch shoulders. And some in the Democratic Republic of the Congo do a type of head knock.

But the American fist bump stood apart from the rest.

Knocking knuckles was the only greeting we could find that signaled both victory and equality; neither bumper has the upper hand, so to speak.

But of many of our readers pointed out that bumping fists may have another superior quality: it's cleaner than a traditional handshake.

Now scientists in Wales have confirmed what these astute reader's already knew. You're much less likely to pass along bacteria when you bump fists than shake hands or high-five, biologists reportedMonday in the American Journal of Infection Control."

Close to ESO's ALMA Observatory, a tour bus creates a cloud of dust as it makes its way across the Chilean desert. This bus carries staff heading to the ALMA Operations Support Facility for the start of an 8-day shift. In the background we see two volcanoes, their snow-covered peaks obscured by clouds.

Located on the border between Bolivia and Chile, these two inactive volcanoes, despite being just a short distance from each other, were created in different geological epochs — Licancabur, the volcano on the left, is much younger than its smaller neighbour Juriques.

Licancabur is famous for its near-symmetrical shape, and for being home to one of the highest lakes in the world. At an altitude of 5916 metres, the lake in Licancabur’s caldera is host to a variety of rare flora and fauna, and has been studied to see how life is coping in this extreme environment. It is said that the Licancabur region is one of the best analogues for the Martian environment, and that by studying the life present here, we may better understand how life could flourish on other planets.

At last, here's the official announcement: Opportunity is now the solar system's long-distance champ, having driven more than 40km[1] across Mars's Meridiani Planum. That beats even the amazing record (about 39km) set by the Soviets' Lunokhod 2 way back in 1973.

The emotions I'm feeling are, I assume, akin to what you feel when your kid goes off to college. At least if college is 225 million km away. I watched her being built; I saw the launch; I was there when she landed. I guided her gently away from near-death experiences. I helped her achieve some of her greatest victories. I wrote the software we used to drive her every centimeter of that 40km, the software that's still used to drive her around. I ... wow, the list just goes on and on.

And I guess I did something right, because she calls home almost every day. She's a good old girl.

And she is now, officially, also a champion.

[1] For those of you who prefer Roman units, 40km is about XXV miles. (When you use Roman units, you should use Roman numerals with them, and for the same reason: why make computation easy?)

You see, when the most famous telescope of our time — the Hubble Space Telescope — was first launched, it was outfitted with a defective mirror!

"[...] Although altruism drove the campaign, leaders of the major industrialized states were motivated by a pragmatic fear of contagion.

North America and Western Europe, where indigenous smallpox had been eliminated, still remained vulnerable to travelers arriving from countries where reservoirs of the disease persisted. The United States alone was spending over $1 million a year on childhood vaccinations, border surveillance, and quarantines—with good reason. In 1947, a fatally infected American returning from Mexico triggered a crisis in New York City that led to the emergency vaccinations of an estimated 6 million people. In 1961, a Pakistani visitor to Britain started an outbreak that required the vaccination of 5.5 million. In 1972, all of Yugoslavia was put under quarantine and 20 million people were vaccinated after a pilgrim returning from the Middle East started a chain reaction of virulent smallpox that quickly spread from Kosovo to Belgrade.

The casualties were few but the bottom line was that even one smallpox case could shut down commerce, close cities, and create a financial crisis. [...]"

"As reported recently in Nature, physicists at the Weizmann Institute of Science used a similar trick to measure the interaction between the smallest possible magnets – two single electrons – after neutralizing magnetic noise that was a million times stronger than the signal they needed to detect.
Dr. Roee Ozeri of the Institute's Physics of Complex Systems Department says: "The electron has spin, a form of orientation involving two opposing magnetic poles. In fact, it's a tiny bar magnet." The question is whether pairs of electrons act like regular bar magnets in which the opposite poles attract one another.
Dr. Shlomi Kotler performed the study while a graduate student under Dr. Ozeri's guidance, with Drs. Nitzan Akerman, Nir Navon and Yinnon Glickman. Detecting the magnetic interaction of two electrons poses an enormous challenge: When the electrons are at a close range – as they normally are in an atomic orbit – forces other than the magnetic one prevail. On the other hand, if the electrons are pulled apart, the magnetic force becomes dominant, but so weak in absolute terms that it's easily drowned out by ambient magnetic noise emanating from power lines, lab equipment and the earth's magnetic field".

Kerry's bullshit "hot mic" run to Israel quickie cease-fire reveals him to be all show, no go

Kerry’s error has been to put so much emphasis on achieving a quick halt to the bloodshed that he has solidified the role of Hamas, the intractable, unpopular Islamist group that leads Gaza, along with the two hard-line Islamist nations that are its key supporters, Qatar and Turkey. In the process, he has undercut not simply the Israelis but also the Egyptians and the Fatah movement that runs the Palestinian Authority, all of which want to see an end to Hamas rule in Gaza.

The Secretary of State is a great test for anyone to be President.  It's  too bad that both Hillary & Kerry have done so badly at it, but good that we at least know how much bullshit they're made of and how much shit they'll happily shovel.

It's a big let down. Previously, I would have preferred to see either of them be President. But not now.

"NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover."

Imagine the dominant form of life on Earth blithely pouring out megatons of pollution into the air, generation after generation. As you might imagine, it doesn't end well.

Robots helped inspire deep learning and might become its killer app

Andrew Ng knows a lot about both deep learning and robotics, and he recently presented on how the former might affect the latter. Robot brains will need to train on a lot of data, and deep learning seems like a good way to do it.

Best time to see 2014 meteor showers? Right about ... now!

"Two meteor showers are converging this week, and you don't want to miss the show.

Monday evening marks the peak of the Delta Aquariids, which can produce up to 20 meteors per hour. Astronomers are still not sure which comet is responsible for the trail of orbiting debris and dust that causes the shower, but regardless, you'll get the best view of the meteors after midnight."

Hoover House

Located next to the stamp mill in the ghost town of Bodie, the Hoover House boasts one of the best views of town from it's front porch. Sitting at 8300', the Milky Way provides a beautiful contrast against the vast canopy of stars. +Jeff Sullivan #bodie #ghosttown #hooverhouse

Science of brain signals opens new era for advertising

Making no judgement but guessing it will become more prominent. 

Companies in the near future will be able to test public reaction to advertisements, music and films before they are released by monitoring the brain signals of a select group as they watch a trial.

"Research shows that flow is most conducive to creativity, not obsessive passion. The positive emotions and intrinsic joy that is associated with harmonious passion is what propels one to greatness, not the negative emotions, compulsions, and unstable ego that is associated with obsessive passion."
