Man and the moon




Turns out Edgar Allan Poe wasn't too far off when he imagined Hans Pfaall making it all the way to the moon thanks to an ingenious balloon.  Kal Penn was showing on The Big Brain Theory how inexpensive it has become to get satellites into the stratosphere thanks to high altitude balloons for as little as $1500.  Here's one home project that reached a height of 124,000 feet or about 38 km.

Space, or at least the inner edge of it, is now in reach to most amateurs with a sense of adventure.  Of course they take the view in vicariously through a camera mounted inside the tiny capsule with a transmission device relaying the feed back down to earth.  It takes a little more effort and a lot more money to reach space yourself, but this is also being done at the amateur level.

Unfortunately, no one has figured out how to break into space itself as Hans Phaall did.  At present, it requires an enormous amount of thrust, which you are not going to do with a balloon.  After a certain point, these balloons explode and the only thing you have is a parachute to cover the 30+ km. free fall back to earth, which takes a very brave person to endure.  But, maybe there is a window in the ozone layer big enough for a balloon to squeeze through.

In any case, space is fast becoming the place for a whole new realm of experimentation and we have Edgar Allan Poe to thank for planting the seed all those years ago.  The amusing thing is that many actually believed that Poe's Great Moon Hoax was real, much like there were many who fell for Orson Welles' reading of War of the Worlds.  While an alien invasion still seems pretty far away, finding alternative ways to reach the cosmos is not.



Clearly we have to think beyond conventional means, as it will be a very long time before we get a man to Mars, the next bold frontier which has Elon Musk already taking reservations.  His SpaceX program took a big hit this past week when he failed to get one of his rockets out of the troposphere to resupply the International Space Station,  Fortunately, there was no one onboard.  Ever since NASA closed its space shuttle program it has been looking for private contractors to provide a means of reaching the space station.  As it is now, we are relying on Russia to deliver astronauts and supplies.

There is even talk of building a space elevator, first broached in the late 19th century by Russian scientist Konstantin Tsiolkovsky.  Tokyo based Obayashi plans to have one in place by 2050.  But, something like this has very serious limitations.

Gravity is a real bitch, and this seems to be what is holding us back, quite literally.  It's relatively easy to overcome this in theoretical models and in movies like Interstellar.  Neil DeGrasse Tyson notes that time is a dimension we also need to overcome if we plan to take any long range human missions.  For now, we will have to content ourselves with NASA's long anticipated flyby Pluto, boldly going where no man is able to go.

The Triangle Shirtwaist Factory Fire

  Welcome to this month's reading group selection.  David Von Drehle mentions The Melting Pot , a play by Israel Zangwill, that premiered on Broadway in 1908.  At that time theater was accessible to a broad section of the public, not the exclusive domain it has become over the decades.  Zangwill carried a hopeful message that America was a place where old hatreds and prejudices were pointless, and that in this new country immigrants would find a more open society.  I suppose the reference was more an ironic one for Von Drehle, as he notes the racial and ethnic hatreds were on display everywhere, and at best Zangwill's play helped persons forget for a moment how deep these divides ran.  Nevertheless, "the melting pot" made its way into the American lexicon, even if New York could best be describing as a boiling cauldron in the early twentieth century. Triangle: The Fire That Changed America takes a broad view of events that led up the notorious fire, not...

Team of Rivals Reading Group

''Team of Rivals" is also an America ''coming-of-age" saga. Lincoln, Seward, Chase et al. are sketched as being part of a ''restless generation," born when Founding Fathers occupied the White House and the Louisiana Purchase netted nearly 530 million new acres to be explored. The Western Expansion motto of this burgeoning generation, in fact, was cleverly captured in two lines of Stephen Vincent Benet's verse: ''The stream uncrossed, the promise still untried / The metal sleeping in the mountainside." None of the protagonists in ''Team of Rivals" hailed from the Deep South or Great Plains. _______________________________ From a review by Douglas Brinkley, 2005

The Searchers

You are invited to join us in a discussion of  The Searchers , a new book on John Ford's boldest Western, which cast John Wayne against type as the vengeful Ethan Edwards who spends eight years tracking down a notorious Comanche warrior, who had killed his cousins and abducted a 9 year old girl.  The film has had its fair share of detractors as well as fans over the years, but is consistently ranked in most critics'  Top Ten Greatest Films . Glenn Frankel examines the origins of the story as well as the film itself, breaking his book down into four parts.  The first two parts deal with Cynthia Ann Parker and her son Quanah, perhaps the most famous of the 19th century abduction stories.  The short third part focuses on the author of the novel, Alan Le May, and how he came to write The Searchers. The final part is about Pappy and the Duke and the making of the film. Frankel noted that Le May researched 60+ abduction stories, fusing them together into a nar...
