Are Eclipse Pundits Out of Touch?

As most people (at least the intelligent people who read blogs like this one) are aware, there will be a major total solar eclipse on August 21st, 2017.  This will be the first total solar eclipse to cross a large portion of the United States since 1979.

There are also a number of people and websites promoting this event and discussing many aspects of the upcoming eclipse.  Some of these experts are undoubtedly well known to those who follow space science.  While they go on and on about how communications have improved since 1979 and how the social media we have now was not around back then, there is one major change in our society that these eclipse pundits have ignored, willingly or otherwise.

This condition is true of quite a few people who would like to observe the total phase of the eclipse

The eclipse pundits, in their effort to show off their calculation skills as well as sell safe solar viewers, maps of the eclipse path, eclipse books, and other related chotchke, have failed to realize that the ranks of the working poor have swollen since 1979.  A very large and growing number of the American public is poorer now than they were in 1979.  What does this have to do with the eclipse, they might ask?  Quite a bit.

While most of the country lives within several hundred miles or so of the path of totality, weather prospects are not equally good along the whole length of the path.  If one wants a reasonable guarantee of the weather, they have to go out west to states like Oregon (the eastern part), Idaho, Wyoming, and Nebraska.  Unfortunately, if most people want to get to those destinations in a reasonable span of time, that means flying.  And, in addition to the airline industry abuses that have made it into the news recently, flying is a major hassle and is very expensive (as I wrote in my previous eclipse post, I predict airfares will experience a sharp upward spike just before the eclipse).  Add the other associated expenses, flying to see the eclipse will cost quite a bit, possibly beyond the reach of observers who aren’t well off.

Then there is the option of driving.  While it is flexible, it does have some downsides.  For one, the range is considerably limited and it takes quite a bit of time to cover significant distance.  And, given the fact that when one reaches their destination, weather prospects could force them to drive even further, possibly hundreds of miles. This makes it a bit difficult for some working poor to figure out how much time to budget for an eclipse trip.  While some have paid vacation time they can take (they still need to figure out how much time an eclipse trip would need), others do not have that luxury.  In other words, they can take the time off, but they won’t get paid for it.  In that case, they would have to balance how much pay they can afford to lose with the other costs of an eclipse trip.  Don’t count on being able to reduce the time of an eclipse trip by speed.  In addition to the likely traffic congestion on major roads leading to the track of totality, it is very likely that local and state law enforcement anywhere near the path of totality will be out in full force looking for anyone who puts the pedal to the metal as well as anyone who puts in marathon driving sessions (the police can bust people for driving tired).  And, according to posts on some eclipse forums, parking regulations will be very strictly enforced as well.  Another factor that has to be considered is the price of gas.  I would not be surprised to see a major upsurge in the price of gas around eclipse.  The people who run oil companies may have been born at night, but it wasn’t last night.  It is very unlikely that these companies are totally unaware of the eclipse.  Since most cars can only go about 200+ to about 300 or so miles on a tank of gas, there could be several fill ups involved in an eclipse road trip.

This discussion of time brings up another issue: accomodations.  Already there have been numerous reports of motels engaging in price gouging for accomodations anywhere near the path of totality.  Expect to hear more as time goes on.

Now, how do the eclipse pundits propose on dealing with these problems, if they even acknowledge them at all?  One solution that has been proposed smacks of the logic Marie Antoinette was said to have used when she was informed of the bread shortage in Paris (and supposedly uttered “Let them eat cake”).  Some pundits have proposed that people get RVs (Recreational Vehicles).  This ignores the obvious facts that RVs are very expensive vehicles and tend to have rather poor gas mileage.  They also do not consider that an RV can’t generally be parked just any old place when used for the purpose of lodging.  That means one also has to find an appropriate place to stop, something that might be scarce in the days before the eclipse.  Yes, I have learned that it is possible to rent RVs, but that isn’t terribly cheap and might be daunting to someone who is unfamiliar with RVs.

Another proposal is that people camp.  While this does get around the enormous cost of the RV suggestion, it has some problems of its own.  You just can’t pitch your tent anywhere.  Several years back, there was this little old thing known as OWS (Occupy Wall Street)* where a number of people pitched tents in Zucotti Park in New York City and caused much consternation with the city government.  Also, in recent years, there have been a number of occasions where homeless people have set up tents in spots that were not considered appropriate.  Local governments have undoubtedly learned from those events and naturally restrict camping to certain areas, mostly campgrounds that have been set aside for such purposes.  And with such areas, one needs reservations.  If you have to change plans due to the weather, there goes whatever you spent on the reservation (that would also apply to anyone who books a motel).  Even if you are able to camp, there is the obvious lack of amenities and that could be an issue for those who are unfamiliar with camping.  (* The Occupy Wall Street reference is for historical purposes only.  This blog does not necessarily agree or disagree with the cause)

One of the most limited proposals I have read suggested staying with friends or relatives who are near the path of totality.  While this does get around some of the problems, it absolutely requires that one have friends or relatives who live near the path of totality and would not mind visitors staying at their place for a while.

The eclipse pundit approach to solving eclipse travel problems can be described charitably as throwing spaghetti against a wall in that they will throw out any idea, regardless if it is practical, that crosses their minds and hope something sticks.  Less charitably, but probably more accurate, is that they are simply out of touch with the socio-economic reality many Americans live with.  It takes surprisingly little to join the ranks of the working poor.  An unexpected expense, a downturn at work, or a combination of these is all it takes.  And given the fact that many people in the private sector have not seen any real raise in years means that recovering from a downturn in fortunes is slow at best.  Most of these eclipse pundits are fairly secure in their financial situation and they think little of traveling hundreds or thousands of miles for an eclipse.

As illustrated by the issues brought up during the March for Science this past April, now is not a good time for science to ignore a growing segment of the American society.  Given the challenges science faces with this administration, it needs all the public support it can get.

Does anyone have real workable ideas as to how people can resolve these issues surrounding the Great American Eclipse?  Do you think my assessment of eclipse punditry is too harsh?  If so, feel free to defend the eclipse experts.  Let’s hear from you.

Has Science Been Fair to the Fair Sex?

I know Women’s History Month is almost over, but the points raised in this post are still very valid.

The film, “Hidden Figures” has been in the news quite a bit recently.  It is a dramatization of the real-life story of Katherine Johnson, Dorothy Vaughan, and Mary Jackson, three African-American women who did heavy-duty mathematical calculations at NASA in the 1960s. Even though computers did exist in those days, they were the size of large refrigerators and had far less computing power than even the lowly Commodore VIC-20 (a nearly 40-year old personal computer).  Thus, humans were still needed to do the mathematical work that the early manned space missions required.

However, those women had several things going against them.  One was that they were women.  Another was that they were African-American.  On top of that, NASA facilities were mostly in the South.  In the case of Kennedy Space Center (though it wasn’t called that until after the assassination of John F. Kennedy), it was due to considerations of orbital mechanics.  As for the other NASA centers, it was to placate influential politicians.  As a result, segregation was in full force at the time.  Johnson and her team worked in a separate office, had a separate lunch area, and were treated as second class people by most at NASA.  However, John Glenn judged them by their work and treated them well.  In fact, he demanded that Johnson personally handle the computations for his orbital flight.

This got me to look back at other women in the history of science.  It turns out that the snubs and treatment that Johnson and her team got were not new.

One famous example was Caroline Herschel.  Due to her growth being stunted in childhood by disease, she was quite short.  On top of that, her parents told her that she would amount to nothing.  However, she helped out her brother, William Herschel, the greatest observational astronomer of his era.  Eventually, she learned enough that she became an observer herself, discovering several deep sky objects as well as a few comets.  Despite her superb training, her contributions were largely forgotten.  Even among modern astronomers, she is little known.

Another case was Maria Mitchell.  She was born into a Quaker family and, since the Quakers believed in equal education, she received far better education than most women of that era.  Mitchell developed an interest in astronomy early in life and became one of America’s first professional astronomers and the first female one.  During the 1840s, the King of Denmark gave an annual award to people who discovered comets.  In 1841, Mitchell discovered a comet and was up for the award.  However, there were astronomers who felt that she did not deserve to get it and raised quite a furor over the matter.  Finally, the Danish authorities intervened and Mitchell got her medal.

Jumping forward to the early 20th century, Harvard Observatory hired a number of women to do mathematical work and measurements of images on glass photographic plates.  Much like Katherine Johnson and her team, these women were referred to as “computers”.  Unlike Johnson, these computers earned sweatshop wages.  But, it was far safer than most of the work women got in that era, working in dangerous mills as well as garment manufacturing (anybody recall the Triangle Shirtwaist fire?). One of these women, Henrietta Swan Leavitt was assigned the task of studying stars on glass photographic plates.  Her job was to locate stars in the Magellanic Clouds that varied in brightness.  Doing so, she discovered that one class of stars (what we call Cepheid variables) had a brightness that was proportional to their period (cycle of variability).  This became known as the period-luminosity relationship and laid the foundation for finding distances to nearby galaxies.  Since she was just a lowly computer, her bosses took credit for the discovery.  But the truth eventually won out and the story is well known in astronomical circles today.

I could go on and on with other examples, such as the career of Lise Meitner, who had to contend with sexism as well as the rise of Nazi Germany, the story of how Watson and Crick might have “borrowed” information from a female colleague to aid their discovery of the structure of DNA, but here is a case of how a woman scientist made a discovery, only to have it stolen from her.

In 1968, Jocelyn Bell was working at Cambridge when she made an odd discovery.  When the radio telescope was pointed at a spot in the constellation of Vulpecula, a rapid pulsing signal was detected.  The pulses were very precise, enough that some people thought it was an alien radio beacon.  This idea soon fell by the wayside and it was learned that the object responsible was a pulsar, a rapidly rotating neutron star that emitted radio energy like the beam of a lighthouse.  Once the significance of this became apparent, Anthony Hewish and Martin Ryle, Bell’s bosses, took credit for the discovery.  Though she did win a Michelson Award (along with Anthony Hewish) in 1973, she was totally ignored when the Nobel prize in physics was handed out in 1974 with Hewish and Ryle getting the prize.  Despite protests from other prominent physicists, Bell was denied Nobel recognition.  While the history books got things right in the end, it was too late for Bell to get the prize.  But she was made a Dame by Queen Elizabeth II some years later.

Sometimes, the side of good wins.  In 1979, Voyager 1 passed through by Jupiter and made many observations.  About three days after closest approach, navigation engineers were poring over the images sent back.  This was to refine the position of the spacecraft as well as the orbits of the Galilean moons.  One of those people, a woman by the name of Linda Morabito, noticed something odd in an image of Io.  It appeared that there was a limb of another moon peeking out from behind Io. Instead of jumping to conclusions, Morabito enhanced the image and, probably echoing the thought of Han Solo when he first saw the Death Star, found that was no moon.

The first image of Io’s volcanism

It was actually the plume from a volcanic eruption on Io, the first display of active volcanism outside Earth.  Morabito was determined to get credit for this find and pushed her case.  Finally, with the mainstream media on her side, she was credited with the find, securing her place in scientific history.

These days, Morabito is involved in advocating for science.  In additon to her personal website, she also maintains a Facebook group, Linda Morabito’s Space Place where she offers commentary on various scientific issues.

So, as Women’s History Month draws to a close, remember the contributions women have made in science and let’s hope for the day when science gives credit where it is due without regard to whether it was a man or a woman who made the discovery.

Lunar Mythbusting

Tonight is October 8th, which has been declared International Observe the Moon Night (IOMN).  Personally, I would choose a date as close to September 13th as possible to take a jab at the late Gerry Anderson and his bit of lunar lunacy known as “Space: 1999”.  Yes, I know I missed that date as well on this blog, but I had other issues to deal with.  With IOMN clouded and/or rained out tonight for a large portion of the United States, I thought I would provide some educational lunar entertainment to make up for it.  So, I dusted off an article I wrote for the Asterism (AAI’s long-defunct newsletter) and I’m using it for material here.

Some years ago, I went to a convention and saw Dee Wallace, best known for playing the mom in E.T. The Extraterrestrial. She was quite nice and she was also there to push DVDs of “The Howling”, a werewolf movie she was in. I took the opportunity to explain to her that I didn’t find werewolf stuff too interesting due to my knowledge of the Moon and the fact that it exerts no strange influences. Dee agreed, but she said that the myths about the Moon were quite pervasive in popular culture, even after the Apollo astronauts walked on the Moon without anything strange happening to them. So, let’s take a detailed look at why the Moon, while interesting, is not mystical.

Time and Tides: People who believe in the mystical powers of the Moon often point out that it could exert its spooky actions through tidal forces. On the surface, this might seem reasonable. After all, anyone who has spent more than a few hours by the ocean or a bay has noticed that the water rises and falls due to tides. Some have argued that, since the ocean is water and people are mostly water in terms of composition, lunar tides should affect people and their behavior. They point to claims of increased weird behavior at times of full Moon and then the old stories always say that werewolves change from people to beasts at full Moon.

However, the “Full Moon effect” has been shown to be false by numerous statistical studies. Also, if one knows how tides work, it is easy to see that they cannot influence living beings.  Tides result when the side of an object nearest a gravity source experiences a greater pull than the opposite side does.  In the case of the oceans, the sea facing the Moon is about 8,000 miles closer to the Moon than the ocean on the opposite side of the Earth. Since the Moon is about a quarter of a million miles away, the diameter of the Earth is a measurable fraction of that distance and the ocean feels the effect of the difference.

Now, consider the case of a human being. To make things as fair as possible to the werewolf buffs, our example will be a player from the NBA who is seven feet tall. The difference in the pull of lunar gravity between the top of his head and the soles of his feet is so close to zero that it can be considered zero for any practical purpose. Even the varying distance of the Moon from Earth (the Moon’s orbit is slightly elliptical), while important for ocean tides, does not alter this conclusion.

It could be argued that tides do influence some living creatures since a number of sea animals lay eggs at times of very high tides. This is the result of their biological clocks, not lunar influence. And they are not infallible tide predictors as the large number of horseshoe crabs that die stranded on beaches each spring can attest to.

Blinded By The Light: Anyone who has been at an observatory on a public night during a full Moon knows it can appear very bright, especially through the telescopes. This brightness is deceptive. Actually the Moon reflects light about as well as the pavement of a road (an albedo of about 7%). It appears bright because the Moon is surrounded by nonreflecting space, so even a dark object like would appear bright. But that is not the whole story.

It is known that the full Moon appears about ten times as bright as it does at first or third quarter. Before people knew much about the Moon, this must have appeared strange. But there are two reasons for this effect. First of all, during full Moon, the Sun is overhead as seen from the lunar surface. There are no shadows. At other times, there are always some shadows formed by mountains and crater rims. But the other reason was only discovered after the Apollo missions returned lunar samples to Earth.

Most of the Moon is covered in a layer of dust, which is essentially lunar rock that has been pulverized by eons of micrometeorite impacts. When samples of this dust were studied on Earth, it was discovered that there were numerous tiny bits of glass in it. The glass formed as the impacts of micrometeorites melted little bits of surface material. The bits of glass give lunar dust a weak retroreflective property like those reflectors embedded in many roads. Due to this effect, the lunar dust actually reflects a bit more light towards Earth at full Moon.

No Cheese, Green or Otherwise: The final proof against strange lunar influence is the composition of the Moon itself. It is now widely believed that Moon formed as the result of a collision between Earth and a Mars-sized planetesimal in the early days of the solar system, which sent debris from the Earth’s mantle into space.

Because of this origin, only about a dozen minerals make up the Moon. Besides basalt and anorthosite (basic igneous rocks), most of these are oxides of iron, titanium, chromium, aluminum as well as some silicates, along with some minerals rich in potassium and rare earth elements. Recently, something new has been added to this list. In 1998, the Lunar Prospector probe found evidence of hydrogen-rich material in some permanently shaded craters near the lunar South Pole. While it could be buried water ice from ancient comet impacts, hydrated minerals and cometary hydrocarbons have not been ruled out. While this mix of minerals is interesting to those who want to build lunar bases, it is about as non-mystical as one can get.

As one can see, the Moon is an interesting place with great potential importance for humanity’s future. Now, isn’t this far more interesting and exciting than mysticism and werewolf stories?

Happy 50th Anniversary!

Thursday, September 8th, 2016 marks the 50th anniversary of a cultural milestone – “Star Trek” as the original series premiered on September 8th, 1966.  While this blog discusses issues of a scientific and/or historical nature, this anniversary was one of those occasions that cannot be ignored.

As most people, especially those intelligent folk who read blogs like this one, know, “Star Trek” followed the exploits of the crew of the Starship Enterprise and its womanizing egotistical captain James T. Kirk.  Despite not being terribly popular during its original network run, struggles with budgets, and other pains, the series became legendary.  This was in part due to its success in syndication, but it also was due to the writing, the characters, and the stories.  While the late Joseph Campbell (professor of Comparative Religion at Sarah Lawrence college and renowned expert on the connections between mythologies and religions) never mentioned “Star Trek” as far as I can determine, Casey Biggs (Damar on “Star Trek: Deep Space 9” and a fan of Campbell’s works) believes that the “Star Trek” franchise fills the function of a mythology in modern society (a system of stories that metaphorically explore universal truths).  This is probably the key to its grip on the public mind.

Before this gets too mythological, it should be noted that the “Star Trek” franchise was extremely influential on our society.  It is generally thought that the concept of the flip phone was inspired by the communicators from the original series.  Today, scientists who are working on handheld analyzers say they are inspired by the tricorders (very portable scanning devices) from the franchise.  And the people involved in research on artificial vision systems that promise to help blind people all say they found inspiration in the visor worn by Geordi LaForge, a blind character from “Star Trek: The Next Generation”.  Those who work on non-lethal weapon technology cite the phaser (the standard issue Starfleet weapon) as their ideal, since it could be set to stun enemies rather than kill them.

However, “Star Trek” has also inspired a number of scientific cul-de-sacs or outright dead-ends.  One prominent example is research into teleportation.  It is thought to have been inspired by the transporter used in the franchise, a device used to transmit matter (people, cargo, or whatever) from point A to point B.  The reason it was used in the series was not because people believed it would be developed in the future, rather it was because Gene Roddenberry wanted a way to get people from the Enterprise to a planet surface and could not afford to do special effects shots of the shuttlecraft transporting people to their destination.  But when people saw it on the show, many believed that if it was on “Star Trek”, it was in our future.  What real teleportation does is it merely transfers the quantum state of a particle to a similar particle some distance away.  While it is impractical for Trek-style uses, it is expected to play a part in quantum computing technology.

Another Trek-inspired false lead is warp drive.  Warp drive was how starships were able to travel throughout the galaxy in reasonable time scales without messy things like Lorentz contraction, time-dilation, and those other nasty relativistic effects that happen when one travels near the speed of light.  While the idea of a warp drive does not seem to contradict relativity and there is (if you accept cosmic inflation) one example of something that was similar to warp physics – the cosmic inflation that explains why the universe appears flat and also why there is so little variation across the Cosmic Microwave Background.  In that case, space itself expanded – for a very brief time – at speeds that would make the Enterprise-E (the latest version of the ship) look extremely sluggish.  Cosmic inflation was thought to be the result of processes associated with the Big Bang.

But this didn’t stop Mexican physicist Miguel Alcubierre from coming up with an idea for a warp drive to move starships.  However, Alcubierre found a problem that has persuaded most physicists that the idea of warp drive was crazy to begin with.  In the original equations, the energy required is truly enormous.  It would take energy equivalent to the entire mass of Jupiter (remember E=MC2?) to generate a tiny warp field.  And if it could be generated, it would be virtually impossible to control.  However, NASA scientist Harold White has picked up where Alcubierre left off and is studying the idea.  White claims that, if the shape of the warp field is modified, the power requirements are reduced to the energy equivalent of a ton of matter.  That is still quite a bit of energy.  White has also claimed that his tiny-scale experiments have gotten some results, though most people think that White was merely observing some kind of quantum phenomenon unrelated to what he is looking for.

Of course, there are the people who like “Star Trek”.  And to the surprise of some people, not all fans of the franchise are like those negative stereotypes seen on “The Big Bang Theory” (discussed in my earlier post about that program).  Among the people who like the Trek franchise are many NASA employees, most astronauts, many professionals from all walks of life, the late Dr. Martin Luther King, Jr. and even one head of state (King Abdullah II of Jordan).

Then there are some surprising folk who really liked “Star Trek”.  Nichelle Nichols, the actress who portrayed Nyota Uhura on the original series, was at a book-signing in London when an enormous man with a shaved head, numerous tattoos, and all the regalia of a skinhead walked into the store.  Even the security guards were frightened.  The man then said that he stopped by because he had a message for Nichelle.  He explained that he used to be a skinhead.  One night, while he was bored, he turned on the TV and a station was running a marathon of “Star Trek” episodes.  As he was watching, he noticed how the crew got along with one another and how they dealt with various moral issues.  He then decided that the skinhead life was not the way to go.  The man then thanked Nichelle for her work on the series and offered his help if she ever needed any assistance during her stay in London.

Naturally, when there is something that popular, there are always those to try to denigrate its positive contributions.  On top of the vast multitude of negative stereotypes of fans, there are incidents that are even uglier.  A few years ago, the weekend edition of “Good Morning America” did a story on research into visual prosthetics.  Some of you might remember from an earlier paragraph that almost every scientist in that field was inspired by Geordi LaForge and his visor.  Did the GMA story bring that up?  No, it didn’t.  Rather than crediting the correct inspiration, they tried to imply it was inspired by Steve Austin’s bionic eye on “The Six Million Dollar Man”.  Those of us who knew the truth were not taken in, but some people might have been.  Why did the folks at GMA do this?  One could argue they disliked the Trek franchise.  I suspect something more vile.  Steve Austin was portrayed by Lee Majors, a white actor.  Geordi LaForge was portrayed by the talented LeVar Burton, an African-American actor.  Was racism involved?  Given our society, it can’t be ruled out.

On a happier note, I have been fortunate enough to have met most of the surviving actors and actresses from Trek franchise as a result of my convention travels.  They are all interesting people and all deserve credit for being part of the success of the Trek franchise.  With the J. J. Abrams movies and their alternate take on the Trek universe, the upcoming “Star Trek: Discovery” series, as well as tons of fan-created stories, songs, etc., who knows what’s going to happen at the next milestone anniversary?  And what do you think of this magnificent franchise?

In honor of this occasion, I leave you with a video featuring one of the franchise’s most beloved characters – Montgomery “Scotty” Scott.  The video was released by Paramount shortly after James Doohan, the actor who created the character, passed away.

 

 

Why Wink When You Should Salute?

August 25th, 2016 marks the fourth anniversary of the death of Neil Armstrong, the first human being to set foot on the lunar surface.  Shortly after his death, the Armstrong family announced that, to honor Neil, every August 25th, people should wink at the Moon if they see it.  I feel that does not go far enough.  One should salute it instead.

One of the main reasons for this was that the man was a true American hero.  While taking over the lunar module’s controls to steer the craft away from a field of boulders that would have brought the mission to a fatal end would be considered a very heroic feat, it wasn’t his only one or even his first.

In the Korean War, Armstrong flew fighter jets from a carrier to attack targets in North Korea.  On one of his missions, his plane ran into a cable stretched across a valley by the North Koreans to wreck low-flying American planes.  For most pilots, the level of damage would have been enough to cause the pilot to eject, which would have likely resulted in a stay at a North Korean POW camp.  But Armstrong was no ordinary pilot.  He managed to maintain some control over the plane.  While returning to the carrier was impossible, there was a Marine base that was within flying range.  Armstrong proceeded to fly to the base.  Just before he reached the base, the plane became uncontrollable and he was forced to eject.  Armstrong made it safely to the ground and was promptly rescued by Marines from the nearby base.

Another heroic feat was during the Gemini 8 mission.  This was to test the concept of docking spacecraft in orbit.  The test target was the upper stage of an Agena rocket.  Shortly after docking, the crew noticed the capsule was moving in an odd manner.  Thinking the problem was with the upper stage, they quickly undocked.  The problem only got worse and the capsule started to spin.  What had happened was one of the Gemini capsule’s thrusters got stuck in the on position and was causing the spacecraft to spin, almost to the point of uncontrollability.  Sizing up the situation, Armstrong decided to use the thrusters designed for reentry as a means of stopping the motion, something that nobody had considered.  Fortunately, the maneuver worked but it meant that they had to return to Earth immediately.  But that quick action saved the life of Armstrong and that of his fellow astronaut.

However, heroism wasn’t his only claim to greatness.  There was his character.  He never bragged about his heroic deeds.  When Apollo 11 returned from the Moon, Armstrong was always quick to credit the success of the mission to the vast number of engineers, scientists, and workers who designed and built the spacecraft.  He never lorded his accomplishment over others and, after he retired from NASA, he became a professor of aeronautics.  If our elected officials had only one-percent of his character, this country would be a better place.

Armstrong’s post-Apollo conduct was reminiscent of that of another great American hero – one of our first.  After the Revolutionary War, George Washington could have asked for, and got, anything he wanted.  Yet, he decided to return to his home at Mount Vernon and operate his plantation.  At the end of his two terms (he felt two terms were enough) as president, he again went back home and kept to himself.

So, if you see the Moon on August 25th, don’t wink, salute.  Let’s honor a great American hero, one who never disgraced himself and one we don’t have to apologize for.

T-Minus 1 Year

Today is August 20th, 2016 and that means it is one year until the Great American Eclipse, the first total solar eclipse to cross the continental United States since 1979.  This is the first post on that eclipse and there will be others as we get nearer to the date.

If you want information about the eclipse, such as its path, weather prospects, and such, the official Great American Eclipse website is the best place to look as it is frequently updated, has a wealth of maps, and very detailed information, including input from Fred Espenak, considered by many to be America’s foremost expert on solar eclipses.

While the information on the site is accurate, there are quite a few things that would-be eclipse observers should be aware of.  Most (if not all) the people intelligent enough to read blogs like this one already know that looking directly at any portion of the uneclipsed Sun without proper filters will result in severe retinal damage.  But there are other less obvious issues.

Most people live a considerable distance from the eclipse track (except for the 12 million or so who live on it) and that means that they must travel.  Unfortunately, long distance travel is quite a challenge these days, especially to those who have limited time and limited means.  The pundits say that one should choose their observing spot as soon as possible.  If we lived in a world with perfectly predictable weather, that would be easy.  Unfortunately we do not.  If one is traveling by air, and they see on the weather forecast that the weather their chosen site is going to be bad, that can mean a scramble to select another site, cancel the flight plan, and book another flight.  And as most people realize, changing air travel plans at the last minute can be rather costly.  On top of that, I predict that the airlines will raise airfares substantially next August just because of the eclipse.

Some people will travel by car to an eclipse site.  Driving to an eclipse site does take time and, if one can’t get much vacation time from work, that greatly limits possible eclipse sites.  Car travel does offer flexibility in terms of dealing with the weather, but there is a catch.  Travel range is limited.  According to Sky & Telescope magazine, given one day’s notice of a change in eclipse plans, it is thought that an eclipse observer can cover something on the order of 500 miles or so, depending on how long they plan to drive continuously.  Of course some will try to add to the range by increasing their travel speed.  But the interstate highway system is not like the German autobahn.  There are speed limits.  And I predict that police and state troopers all along the eclipse track will be instructed to be out in force with their radar guns to nab speeders.  According to the Great American Eclipse website, transportation departments in states along the eclipse track are well aware of the upcoming eclipse and I suspect the information will be passed along.

Does this mean that you should give up on observing the total eclipse next year?  Not at all.  It does mean that you should be aware of potential pitfalls when you make your plans.  Future posts will bring up other aspects of this truly astronomical event.  Stay tuned.

Going Buggy Over the Rio Games

Friday, August 5th marks the opening ceremonies of the Summer Olympic Games in Rio De Janeiro, Brazil.  This time around, the Games are quite controversial with allegations of corruption amongst the various contractors, incomplete work, the fact that this is taking place during a political coup in the host country, etc.  But one thing that is getting lots of press is also one of the smallest (literally) issues.

By now, most people have heard about the Zika virus.  It is mainly known from Brazil, though it has appeared in other parts of the world as well, is spread by mosquitoes and, in most cases, the symptoms range from none to rather minor.  That is if the victim isn’t a pregnant woman.  By processes that are poorly understood at present, the Zika virus can cause microcephaly (an abnormally small head due to an abnormally small and deformed brain).  Microcephaly is incurable and untreatable.  Naturally, this has caused a great measure of concern.  So much so that some athletes have bowed out of the Games (even male athletes who, last time I checked, can’t get pregnant).  Even TV networks have changed their plans with NBC replacing some of the female reporters they were originally going to send with Meredith Vieira and Hoda Kotb (that is not a typo – it is an issue of transliterating her Egyptian last name from Arabic writing to Western writing).

There is also some concern in the United States as the mosquitoes we have are capable of carrying the virus.  But what I think has the government in near panic mode is the fact that Zika is a nightmare for the right-to-life crowd.  For most other birth defects, they can argue that, with appropriate therapy, the victims can have some semblance of a life.  They also claim that future advances in fetal surgery and other medical technology can mitigate defects as well.  Not so with microcephaly.  That’s it.  Hence the pressure that is being exerted on the scientific community to derive some sort of method to combat Zika and its mosquito carriers.

At least one scientists claims they found a weak spot in the mosquito genome that would make it possible to wipe them out completely.  Then there is talk that a vaccine is being worked on.  However, given past history in humanity’s struggle to deal with mosquitoes, there is ground for skepticism.  Mosquitoes are highly adaptable and have a proven ability to acquire resistance to whatever insecticide or strategy we can throw at them.  And it does seem unusual that someone claims to be near to developing a vaccine for a virus that is little known.

If the effort to control Zika is as successful as the effort to control other mosquito-borne diseases, Zika is here to stay.  Since it mainly poses a threat to pregnant women, perhaps it might be a good idea to consider strategies from that angle.  Perhaps it might force people to actually put some thought into the idea of whether or not to have kids.  Currently, most people put more thought into choosing players for their fantasy sports teams than they do in reproduction.  There could be other changes in how people reproduce.  Can you think of some?

Of course it could be worse.  In Kurt Vonnegut’s book “Galapagos”, he postulated a microbe that destroyed the ovaries.  It spread throughout the world via air travel until the only group that wasn’t affected was a band of tourists in the Galapagos Islands (hence the title).  Cut off from the rest of the world due to the disease, the tourists are the last breeding set of human beings.  Over long spans of time, the humans gradually evolve into something resembling a very intelligent and dexterous seal.  The story was said to be inspired by Vonnegut hearing about the evolution of Darwin’s Finches (birds on the islands that evolved from a single group of birds blown to the islands in a storm).  Then there is the story and film “The Children of Man” which recounts how human reproduction ceases and the utter chaos that takes place when a pregnant woman is discovered.

While Zika is nowhere near as bad as its fictional counterparts, I think it may take some effort and time to come up with ways to bring it under some measure of control.
