Educational media of yore



From Wikipedia:

The filmstrip was a common form of still image instructional multimedia, once commonly used by educators in primary and secondary schools (K-12), overtaken at the end of the eighties by newer and increasingly lower-cost full-motion videocassettes and later on by DVDs. From the 1940s to 1980s, filmstrips provided an easy and inexpensive alternative to 16mm projector educational films, requiring very little storage space and being very quick to rewind for the next use. Filmstrips were large and durable, and rarely needed splicing. They are still used in some areas.

A filmstrip is a spooled roll of 35 mm positive film with approximately thirty to fifty images arranged in sequential order. Like 16 mm film, a filmstrip was inserted vertically down in front of the projector aperture, rather than horizontally as in a slide projector. Therefore, the frame size is smaller than normal 35 mm film. Two image frames of a filmstrip take up the same amount of space as a single 35mm frame, including its guard band, so that a 25 exposure 35mm film can contain fifty filmstrip images. Early celluloid filmstrips had a habit of melting or combusting from the intense and sustained heat of the projection lamp.[citation needed] These were called pictural filmstrips, the first filmstrips that were produced in a complete set[clarification needed].

Typically, a filmstrip's running time was between ten and twenty minutes. Depending on how they were narrated or produced, filmstrips (which often came with an instructor's guide) were flexible enough to be used in both self-paced learning formats or a full classroom. In addition to a standard classroom wall or screen projector, personal film display units were available with a screen size of approximately eight inches diagonal for up-close viewing by one or two people.

The instructor would turn on a filmstrip projector that would show the first frame (image) of the filmstrip. The instructor then turned on a 33 RPM record or cassette tape containing the audio material for the filmstrip which included narration. At the appropriate point, a tone would sound, signaling the instructor to turn a knob, advancing to the next frame. Later, technical improvements allowed the projector to advance the film automatically.

There is something overwhelmingly quaint about these old filmstrips and learning machines and scratched 16mm movies. It is easy to get distracted by the antiquated analog quality, to focus too much on the technology and not enough on the underlying pedagogy. This, of course, begs the question: why should we care? Other than misplaced nostalgia, what is the value in studying this outmoded educational media?

The answer is that we are currently investing a lot of money and even more hope into the idea that technology can fix many if not most of the pressing problems in our educational system. Add to that, the fact that we have been at this now for over a century. These previous technologies were launched with similar rhetoric and expectations and most if not all either severely underperformed or failed outright. The case for learning exactly what went wrong seems fairly obvious.

“Worldly wisdom teaches that it is better for reputation to fail conventionally than to succeed unconventionally” -- more for the to-blog pile

I really need to do something with this Justin Fox piece:

Are Money Managers Lemmings?

That Keynes quote alone is worth a mega-thread.

The sad part is I'm pretty sure someone would publish it and I'm sure a number of news outlets would pick it up.

Is the attitude toward Israel another left/right axis shift?

I've been thinking for a long time about the different components of the liberal conservative spectrum and the ways they move and interact (this comes up a lot when you dig into the education reform debate). One point of particular interest is the catastrophic shift, cases where the "liberal" and "conservative" positions on an issue suddenly switch places. We've already discussed pacifism. Now this post by Corey Robin (followed by some excellent comments) has me wondering if attitudes about Israel have undergone a comparable shift.

The piece also made me think, though, about the initial reaction to Israel’s decision to try Adolf Eichmann.

The response to that decision, as historians like Peter Novick and Deborah Lipstadt have shown, was rife with anti-Semitism. The Wall Street Journal warned darkly of “an atmosphere of Old Testament retribution.” A Unitarian minister, according to Novick, claimed “he could see little ethical difference between ‘the Jew-pursuing Nazi and the Nazi-pursuing Jew.’” Those unitarian universalists.

The worst offender, though, was National Review. Combining all the elements of anticommunism, Christian homiletics, and ancient Jew-hatred, William F. Buckley’s magazine castigated the Israelis—really, the Jews, those Shylocks of vengeance and memory—for their inability to let bygones be bygones.
I assume support for Israel is now stronger on the right than on the left. Is that true?

Little Technophile on the Prarie

Brad DeLong has an interesting post (from, believe it or not, Laura Ingalls Wilder) that fits in with one of my favorite ongoing threads, the unprecedented transformation of every aspect of life (at least in places like America) that occurred late in the Nineteenth and early in the Twentieth Centuries.

One of my big complaints about tech journalism is the lack of historical context. Reporters see technology changing the world around them and, through a combination of historical illiteracy and self-absorption, they assume this makes them special.

There's no question that technology has had a big impact on our lives over the the past dozen or so years, but in most ways, 2003 doesn't seem that different. For Wilder in 1911, 1899 was, in almost every respect, another world.

Self driving cars

This is Joseph.

A gaming and Shakespeare blog (no joke, it really exists) had a nice argument for why driver-less cars are unlikely to greatly reduce the number of cars needed.

Well worth a quick read.

An April Fool's Day Repost

From July 7, 2014

Over at the New Republic, Julia Ioffe has a fascinating piece on the Russian media's treatment of the downing of MH17:
Did you know Malaysia Airlines Flight 17 was full of corpses when it took off from Amsterdam? Did you know that, for some darkly inexplicable reason, on July 17, MH17 moved off the standard flight path that it had taken every time before, and moved north, toward rebel-held areas outside Donetsk? Or that the dispatchers summoned the plane lower just before the crash? Or that the plane had been recently reinsured? Or that the Ukrainian army has air defense systems in the area? Or that it was the result of the Ukrainian military mistaking MH17 for Putin’s presidential plane, which looks strangely similar?

Did you know that the crash of MH17 was all part of an American conspiracy to provoke a big war with Russia?

Well, it’s all true—at least if you live in Russia, because this is the Malaysia Airlines crash story that you’d be seeing.

As the crisis surrounding the plane crash deepens and as calls for Vladimir Putin to act grow louder, it’s worth noting that they’re not really getting through to Putin’s subjects. The picture of the catastrophe that the Russian people are seeing on their television screens is very different from that on screens in much of the rest of the world, and the discrepancy does not bode well for a sane resolution to this stand-off. 
This reminded me of a conspiracy theory I've considered blogging on partly because it uses such bad statistics to make much of its case, but mainly because it is so incredibly weird. Forget von Däniken and Velikovsky; this is the hard stuff. From Wikipedia:
The New Chronology also contains a reconstruction, an alternative chronology, radically shorter than the conventional chronology, because all ancient history is "folded" onto the Middle Ages. According to the revised chronology, the written history of humankind goes only as far back as AD 800, there is almost no information about events between AD 800–1000, and most known historical events took place in AD 1000–1500.
The main mover for this is Russian mathematician Anatoly Fomenko and he has put in an incredible amount of effort making sure everything fits his theory, including some things that are difficult to ignore:
The Great Pyramids naturally fit in the epoch of the monumental constructions, which blossomed in the XIV-XVI cc. all over the Empire. They are: 1) The Great Wall of China, 2) the magnificent cathedrals of Western Europe, 3) the indomitable Kremlins and fortifications in Russia-Horde, 4) the massive Hagia Sophia in Istanbul, aka (according to our reconstruction) – The Temple of Solomon in Jerusalem = Czar-Grad, 5) the Great Sphinx, [actually "a very familiar Christian Cherubim." Who knew? -- MP] 6) the Great Pyramids and temples of Egypt 7) the great pyramids and temples of Central America, in particular Mexico, 8) gigantic constructions of Baalbeck (Lebanon).
That part about the Russia-Horde is important. (All remaining quotes from Wikipedia):
Central to Fomenko's New Chronology is his claim of the existence of a vast Slav-Turk empire, which he called the "Russian Horde", that played the dominant role in Eurasian history before the 17th century. The various peoples identified in ancient and medieval history, from the Scythians, Huns, Goths and Bulgars, through the Polyane, Duleby, Drevliane, Pechenegs, to in more recent times, the Cossacks, Ukrainians, and Belarussians, are nothing but elements of the single Russian Horde. For the New Chronologists, peoples such as the Ukrainians, Belarussians, Mongols, and others who assert their national independence from Russia, are suffering from a historical delusion. 
That might explain this:
Despite criticism, Fomenko has published and sold over one million copies of his books in his native Russia. Many Internet forums have appeared which aim to supplement his work with additional amateur research. His critics have suggested that Fomenko's version of history appealed to the Russian reading public by keeping alive an imperial consciousness to replace their disillusionment with the failures of Communism and post-Communist corporate oligarchies.
I don't know enough about Russia to even start speculating about the larger question of conspiracy theories in today's Russia. That's a question for people who know what they're talking about. I will, however, note that, if nothing else, Fomenko's New Chronology shows why chess masters might not make such formidable Bond villains in real life.

I realize we're entering dead horse territory here -- UPDATED

... and, as promised in the last post, we are approaching the end of this thread, but I recently came across this article from 2013 and since I haven't said much about those 200,000 applicants...

Private Mars Colony Project Undaunted by Application ShortfallRob Coppinger, SPACE.com Contributor   |   August 28, 2013 07:00am ET

Mars One opened its application process for potential colonists on April 22 of this year and set a deadline of  Aug. 31. Applicants have to pay a fee, which ranges from $5 to $75 depending on which country they live in. The fee for United States citizens is $38.

On April 10, Lansdorp told SPACE.com that Mars One expected to get 1 million applications. By mid-April, the foundation had 45,000 people registered for its mailing list and had received 10,000 emails from individuals. By early May, two weeks after applications opened, Mars One was claiming 78,000 applicants.

At the time, Lansdorp said in a statement: "These numbers put us right on track for our goal of half a million applicants," lowering the applications bar he had set a few weeks earlier.

By Aug. 22, Mars One had received about 165,000 applications, meaning the foundation could have a total of around 200,000 in hand by the Aug. 31 deadline. Lansdorp told SPACE.com on Aug. 23 that potential applicants should not be concerned about any perceived lack of qualifications: "We have the feeling that people feel that, 'If I’m not a pilot or I don’t have astronaut training already, how can I ever be qualified to go to Mars?' And actually, the opposite is true."

The average application fee is about $25, Lansdorp said, so 200,000 submissions would bring in about $5 million. That would leave Mars One $20 million short of what it would have gotten from 1 million applications (and $7.5 million shy of the $12.5 million that 500,000 applications would have brought in).

However, Lansdorp also told SPACE.com last week that the 165,000 included those that had not paid. He declined to say how much revenue applications had generated.

Now cut to 2014 courtesy of Elmo Keep.
Then there’s the company’s claim that 200,000 people applied for a one-way ticket. This incredible piece of information issued by Mars One’s press office was picked up with credulous haste by news outlets around the world. Even religious leaders made their opinions known, with the UAE-based General Authority of Islamic Affairs and Endowment strictly forbidding Muslims from applying, as to leave the sanctity of Earth was an affront to Allah.

But Norbert Kraft, the chief medical officer, has told The Guardian he was sorting through 80,000 applicants, not 200,000. NBC News tallied the number of video applicants on the Mars One website and came to 2,782, each of whom paid an application fee of between $5 and $75. I ask Lansdorp if in the course of fact-checking this story he will allow me to see the list to verify the number. I ask where the 200,000 people registered their interest and if it was ever made public. His answer was…complicated.

“I don’t know if that was ever made public, but they have registered on our website for applying for our program,” he says. “Then there was a number of steps where people had the opportunity to drop out as that was exactly the point. The application process was kind of a self-selection that avoided us having to review all of them. The first step was paying the application fee. A number of people already dropped out there. Then there was a video that you had to make and questions that you had to answer. And that’s also where a lot of people dropped out, that they’re not lying in their motivation.”

I ask again if sharing the list would be possible to verify the figure.

“Of course we cannot share the details of the applicants with you because that’s confidential, private information that we cannot share.”

I offer that the names can be redacted in maintaining the privacy of the applicants before viewing the list.

“Ah, no. I’m not interested in sharing that information with you.”

He emails later, with an invitation to come at my own expense to Mars One’s office in the Netherlands and see the list in person, though cameras will not be allowed. “I will need to read your article before publication and reserve the right to deny you access to the list if I don’t like what you wrote.”

I tell him that of course that won’t be possible.
P.S. And the revision continues. Emphasis added.

From a Pakistani news site:
When Mars One, Dutch non-profit foundation, launched a program to establish permanent human settlement on the red planet, they never thought that they would be swamped with a flood of applications. Shockingly, 202,586 people signed up for this crazy, one-way trip to Mars, of which 100 made it to Mars One’s highly coveted shortlist.

No part of this project is credible

[Coming to the end of the Mars One mega-thread.]

One of the aspects of the Mars One story that I allude to frequently but probably don't emphasize enough is that there is no there there. Every component of the proposal collapses under scrutiny. 

One example I don't believe I've gotten around to is the selection process. 

Take a moment and think about this scenario. You are trying to put together a crew for a long, arduous, complex, insanely ambitious mission with virtually no redundancy. You want to do everything possible to minimize the risk of either a medical or a psychological crisis.

With health concerns in mind, you would probably not want to include a crew member who will be pushing 70* at the beginning of the mission in 2026.
In a decade or so, when most people her age will be retiring from their working lives, Elena Shateni, now 58, plans to be starting a new life planting the human flag on Mars.
While egalitarianism is admirable in principle, in a mission with limited resources and a small crew, there has got to be some level of specialization. Having one crew member lost or incapacitated threatens the safety of the rest of the crew and the viability of the entire mission.

And remember, we are talking about an ongoing mission. This means that crew members need to be performing at full capacity for years to come. It is entirely possible that septuagenarians and even octogenarians could stand up to these rigors and perform these duties. It is not, however, something you would want to count on.

Keeping costs low means avoiding unnecessary risk; it also means avoiding unnecessary drama. We can never say in advance how someone will deal with the stresses associated with physical danger, life in incredibly cramped quarters, permanent relocation, and isolation. We can, however, reasonably assume that certain groups will be at higher risk than others.
George Hatcher welcomed a guest at his Merritt Island home last week with 5-month-old daughter Io, named for one of Jupiter's moons, tucked in a baby carrier on his chest.

Inside, the NASA engineer's wife, Lorenia, took the baby and their 2-year-old son, Rafael, offered a small stuffed lamb and a Thomas the Tank Engine train for inspection.

Hatcher stretched out with Rafael on the living room floor to work on an animal puzzle, then played a game of "tickling spiders" and swung his son high up with his legs, to squeals of delight.

It's family time the 35-year-old father cherishes after a day at work at Kennedy Space Center. But he increasingly has reason to think about the day he might leave it all behind.
...
Hatcher recently advanced to the final round of 100 candidates vying to be selected as astronauts by the Mars One Foundation, which wants to establish a human settlement on the Red Planet in the next decade.
...
Mars One estimates it will cost $6 billion to get the first crew to Mars, a figure many consider optimistic.
[That last paragraph isn't relevant to this post but I just had to throw in the phrase "many consider optimistic."]

Even under normal circumstances, extended or indefinite separation from a child can be extraordinarily difficult on a parent. In times of crisis, it can be almost unbearable. Including parents in the selection pool greatly increases the chance of a mission-threatening breakdown.

These are not isolated cases. If you read over the profiles of the other hundred finalists, you will find a large number who seem obviously ill-suited for this kind of project. People who seem, perhaps not coincidentally, better suited for a reality show.

To get a sense of how this happened, it is useful to take a look at the application FAQ on Mars One's own website. Here's an excerpt;



Characteristic Practical Applications Resiliency
  • Your thought processes are persistent.
  • You persevere and remain productive.
  • You see the connection between your internal and external self.
  • You are at your best when things are at their worst.
  • You have indomitable spirit.
  • You understand the purpose of actions may not be clear in the moment, but there is good reason—you trust those who guide you.
  • You have a “Can do!” attitude.
The rest is not much better. Amateurish, badly thought out, with the language of a motivational speaker not quite covering the lack of any real plans.

Dr. Michio Kaku has perhaps the best quote (buried deep in what is otherwise an ABC puff piece):

“This has the atmosphere of a circus, where you have amateurs simply raising their hand, volunteering to be the first person on Mars.”



* "There is not an upper age limit to apply for the astronaut selection program. If the applicant enjoys good health and he or she has all the other characteristics needed for the mission he or she has what it takes to apply." -- from the website.

Against a stupid meme, the gods themselves contend in vain

One of the most discouraging things about following the coverage of Mars One (and of science and technology reporting in general) is seeing how little important revelations are allowed to interfere with a good ongoing story.

Take the popular journalistic sub-genre, the Mars One "how does it feel to be going to Mars?" interview. It is, largely by design, an almost perfect human interest story. It was also an extremely easy and inexpensive segment to produce.

The weak point of the sub-genre has always been the premise. The dramatic impact depended on treating the project as credible. Keeping that premise believable while maintaining journalistic standards has always been a challenge, but over the past few months, it has become almost impossible.

A quick recap of recent Mars One developments:

The interview process has been revealed as a sham;

The company that was to produce their show has left;

Their contracts with actual aerospace companies are on hold;

Their Nobel Prize winning supporter has admitted that their budget and schedule were overly optimistic by a factor of ten;

A study by MIT PhD candidates has shown that the proposed habitat would probably kill all of the colonists in a matter of weeks.

This should effectively kill off the sub-genre but it hasn't. The trouble is that, other than the whole not being true part, this is still a great story. So we get articles like this one from Steve Annear of the Boston Globe, which slips in just enough inconvenient facts to maintain a pretense.
A Stoneham man is one small step closer to being picked for an ambitious one-way mission to colonize Mars.

Peter Degen-Portnoy was selected as a semifinalist for the “Mars One” project, a nonprofit venture aiming to populate the distant planet within the next 12 years — a plan some say is far-fetched and unachievable.

...

“The whole thing is a dream come true,” Degen-Portnoy, 51, said. “I can totally see myself . . . in that habitat, working with my team and working every day to make sure our systems are functioning and our resources are sufficient.”

Two years ago, Mars One put out a call for submissions from people interested in volunteering their efforts to bring life to the Red Planet. The Dutch organization says it received more than 200,000 inquiries [There's also a bit of a story behind that 200K claim -- MP] before whittling the list down to 100 applicants last month. Degen-Portnoy made the cut. Known as “The Hundred,” the group consists of 50 men and 50 women from around the world.

If all goes well, the husband and father of five could make it to the last round of the process, and join 24 finalists for what Mars One says will be an intense training regimen to prepare for takeoff. Groups of four will then tentatively be launched into space every two years beginning in 2026, with the first landing planned for 2027, according to the Mars One timetable, an aggressive goal that has been challenged by researchers and the public.
...
Degen-Portnoy remains optimistic about the journey to the planet, despite skepticism about the feasibility of the mission. A recent independent study conducted by students at the Massachusetts Institute of Technology pointed out how difficult it would be for Mars One to ship enough supplies to sustain a new civilization. One of “The Hundred” also came forward in a recent interview and called the selection process, financial stability, and goals of the mission into question.

Last week, Bas Lansdorp, chief executive and cofounder of Mars One, tried to put some of those concerns to rest, and invited criticism.

“At Mars One we really value good criticism because it helps us to improve our mission,” he said in a statement.

Even if nothing comes of the actual mission, Degen-Portnoy said the experience and his involvement so far have been worth it. “I have met some incredible people, and we spend a lot of time chatting in our social group, exchanging ideas, and also boosting and supporting one another,” he said.
The list of concerns is both incomplete (check out our last few posts) and comically understated. Lansdorp's claim of welcoming criticism is also good for a laugh. Still, it could be worse. Here's the opening to a recent report from a local NBC station in Philadelphia:
Sara Director has a bright future ahead of her here on earth, but the 26-year-old — originally from the Philadelphia suburbs — is competing for an opportunity to leave that all behind for a one-way ticket to Mars. Upon discovering she made it to the third round of candidates in the Mars One mission, there’s a 25% percent chance that Director will spend the rest of her life on the Red Planet, leaving family and friends behind.

For some reason, this morning I found myself thinking about scams and hoaxes involving space exploration



That lead me inevitably to this New York Sun headline from 1835

GREAT ASTRONOMICAL DISCOVERIES
LATELY MADE
BY SIR JOHN HERSCHEL, L.L.D. F.R.S. &c.
At the Cape of Good Hope
[From Supplement to the Edinburgh Journal of Science]

From Wikipedia:
The articles described fantastic animals on the Moon, including bison, goats, unicorns, bipedal tail-less beavers and bat-like winged humanoids ("Vespertilio-homo") who built temples. There were trees, oceans and beaches. These discoveries were supposedly made with "an immense telescope of an entirely new principle."
...
Eventually, the authors announced that the observations had been terminated by the destruction of the telescope, by means of the Sun causing the lens to act as a "burning glass," setting fire to the observatory




And from Mr. E.A. Poe:

About twelve years ago, I think, “The New York Sun,” a daily paper, price one penny, was established in the city of New York by Mr. Moses [column 2:] Y. Beach, who engaged Mr. Richard Adams Locke as its editor. In a well-written prospectus, the object of the journal professed to be that of “supplying the public with the news of the day at so cheap a rate as to lie within the means of all.” The consequences of the scheme, in their influence on the whole newspaper business of the country, and through this business on the interests of the country at large, are probably beyond all calculation.

Previous to “The Sun” there had been an unsuccessful attempt at publishing a penny paper in New York, and “The Sun” itself was originally projected and for a short time issued by Messrs. Day & Wisner; its establishment, however, is altogether due to Mr. Beach, who purchased it of its disheartened originators. The first decided movement of the journal, nevertheless, is to be attributed to Mr. Locke; and in so saying I by no means intend any depreciation of Mr. Beach, since in the engagement of Mr. L. he had but given one of the earliest instances of that unusual sagacity for which I am inclined to yield him credit.

At all events, “The Sun” was revolving in a comparatively narrow orbit when, one fine day, there appeared in its editorial columns a prefatory article announcing very remarkable astronomical discoveries made at the Cape of Good Hope by Sir John Herschell. The information was said to have been received by “The Sun” from an early copy of “The Edinburgh Journal of Science,” in which appeared a communication from Sir John himself. This preparatory announcement took very well, (there had been no hoaxes in those days,) and was followed by full details of the reputed discoveries, which were now found to have been made chiefly in respect to the moon, and by means of a telescope to which the one lately constructed by the Earl of Rosse is a plaything. As these discoveries were gradually spread before the public, the astonishment of that public grew out of all bounds; but those who questioned the veracity of “The Sun” — the authenticity of the communication to “The Edinburgh Journal of Science” — were really very few indeed; and this I am forced to look upon as a far more wonderful thing than any “man-bat” of them all.

About six months before this occurrence the Harpers had issued an American edition of Sir John Herschell’s “Treatise on Astronomy,” and I had been much interested in what is there said respecting the possibility of future lunar investigations. The theme excited my fancy, and I longed to give free rein to it in depicting my day-dreams about the scenery of the moon — in short, I longed to write a story embodying these dreams. The obvious difficulty, of course, was that of accounting for the narrator’s acquaintance with the satellite; and the equally obvious mode of surmounting the difficulty was the supposition of an extraordinary telescope. I saw at once that the chief interest of such a narrative must depend upon the reader’s yielding his credence in some measure as [page 160:] to details of actual fact. At this stage of my deliberations I spoke of the design to one or two friends — to Mr. John P. Kennedy, the author of “Swallow Barn,” among others — and the result of my conversations with them was that the optical difficulties of constructing such a telescope as I conceived were so rigid and so commonly understood, that it would be in vain to attempt giving due verisimilitude to any fiction having the telescope as a basis. Reluctantly, therefore, and only half convinced, (believing the public, in fact, more readily gullible than did my friends,) I gave up the idea of imparting very close verisimilitude to what I should write — that is to say, so close as really to deceive. I fell back upon a style half plausible[[,]] half bantering, and resolved to give what interest I could to an actual passage from the earth to the moon, describing the lunar scenery as if surveyed and personally examined by the narrator. In this view I wrote a story which I called “Hans Phaall,” publishing it about six months afterwards in “The Southern Literary Messenger,” of which I was then editor.

It was three weeks after the issue of “The Messenger” containing “Hans Phaall,” that the first of the “Moon-hoax” editorials made its appearance in “The Sun,” and no sooner had I seen the paper than I understood the jest, which not for a moment could I doubt had been suggested by my own jeu d’esprit. Some of the New York journals (“The Transcript” among others) saw the matter in the same light, and published the “Moon story” side by side with “Hans Phaall,” thinking that the author of the one had been detected in the author of the other. Although the details are, with some exception, very dissimilar, still I maintain that the general features of the two compositions are nearly identical. Both are hoaxes, (although one is in a tone of mere banter, the other of downright earnest;) both hoaxes are on one subject, astronomy; both on the same point of that subject, the moon; both professed to have derived exclusive information from a foreign country, and both attempt to give plausibility by minuteness of scientific detail. Add to all this that nothing of a similar nature had ever been attempted before these two hoaxes, the one of which followed immediately upon the heels of the other.

Having stated the case, however, in this form, I am bound to do Mr. Locke the justice to say that he denies having seen my article prior to the publication of his own; I am bound to add, also, that I believe him.

Immediately on the completion of the “Moon story,” (it was three or four days in getting finished,) I wrote an examination of its claims to credit, showing distinctly its fictitious character, but was astonished at finding that I could obtain few listeners, so really eager were all to be deceived, so magical were the charms of a style that served as the vehicle of an exceedingly clumsy invention.

It may afford even now some amusement to see pointed out those particulars of the hoax which [column 2:] should have sufficed to establish its real character. Indeed, however rich the imagination displayed in this fiction, it wanted much of the force which might have been given it by a more scrupulous attention to general analogy and to fact. That the public were misled, even for an instant, merely proves the gross ignorance which (ten or twelve years ago) was so prevalent on astronomical topics.

The moon’s distance from the earth is, in round numbers, 240,000 miles. If we wish to ascertain how near, apparently, a lens would bring the satellite, (or any distant object,) we, of course, have but to divide the distance by the magnifying, or, more strictly, by the space-penetrating power of the glass. Mr. Locke gives his lens a power of 42,000 times. By this divide 240,000, (the moon’s real distance,) and we have five miles and five-sevenths as the apparent distance. No animal could be seen so far, much less the minute points particularized in the story. Mr. L. speaks about Sir John Herschell’s perceiving flowers, (the papaver Rheas, etc.), and even detecting the color and the shape of the eyes of small birds. Shortly before, too, the author himself observes that the lens would not render perceptible objects less than eighteen inches in diameter; but even this, as I have said, is giving the glass far too great a power.

On page 18, (of the pamphlet edition,) speaking of “a hairy veil” over the eyes of a species of bison, Mr. L. says — “It immediately occurred to the acute mind of Doctor Herschell that this was a providential contrivance to protect the eyes of the animal from the great extremes of light and darkness to which all the inhabitants of our side of the moon are periodically subjected.” But this should not be thought a very “acute” observation of the Doctor’s. The inhabitants of our side of the moon have, evidently, no darkness at all; in the absence of the sun they have a light from the earth equal to that of thirteen full moons, so that there can be nothing of the extremes mentioned.

The topography throughout, even when professing to accord with Blunt’s Lunar Chart, is at variance with that and all other lunar charts, and even at variance with itself. The points of the compass, too, are in sad confusion; the writer seeming to be unaware that, on a lunar map, these are not in accordance with terrestrial points — the east being to the left, and so forth.

Deceived, perhaps, by the vague titles Mare Nubium, Mare Tranquilitatis, Mare Fæcunditatis, etc., given by astronomers of former times to the dark patches on the moon’s surface, Mr. L. has long details respecting oceans and other large bodies of water in the moon; whereas there is no astronomical point more positively ascertained than that no such bodies exist there. In examining the boundary between light and darkness in a crescent or gibbous moon, where this boundary crosses any of the dark places, the line of division is found to be jagged; but were these dark places liquid they would evidently be even. [page 161:]

The description of the wings of the man-bat (on page 21) is but a literal copy of Peter Wilkins’ account of the wings of his flying islanders. This simple fact should at least have induced suspicion.

On page 23 we read thus — “What a prodigious influence must our thirteen times larger globe have exercised upon this satellite when an embryo in the womb of time, the passive subject of chemical affinity!” Now, this is very fine; but it should be observed that no astronomer could have made such a remark, especially to any “Journal of Science,” for the earth in the sense intended (that of bulk) is not only thirteen but forty-nine times larger than the moon. A similar objection applies to the five or six concluding pages of the pamphlet, where, by way of introduction to some discoveries in Saturn, the philosophical correspondent is made to give a minute school-boy account of that planet — an account quite supererogatory, it might be presumed, in the case of “The Edinburgh Journal of Science.”

But there is one point, in especial, which should have instantly betrayed the fiction. Let us imagine the power really possessed of seeing animals on the moon’s surface — what in such case would first arrest the attention of an observer from the earth? Certainly neither the shape, size, nor any other peculiarity in these animals so soon as their remarkable position — they would seem to be walking heels up and head down, after the fashion of flies on a ceiling. The real observer (however prepared by previous knowledge) would have commented on this odd phenomenon before proceeding to other details; the fictitious observer has not even alluded to the subject, but in the case of the man-bats speaks of seeing their entire bodies, when it is demonstrable that he could have seen little more than the apparently flat hemisphere of the head.

I may as well observe, in conclusion, that the size and especially the powers of the man-bats (for example, their ability to fly in so rare an atmosphere — if, indeed, the moon has any) with most of the other fancies in regard to animal and vegetable existence, are at variance generally with alt [[all]] analogical reasoning on these themes, and that analogy here will often amount to the most positive demonstration. The temperature of the moon, for instance, is rather above that of boiling water, and Mr. Locke, consequently, has committed a serious oversight in not representing his man-bats, his bisons, his game of all kinds — to say nothing of his vegetables — as each and all done to a turn.

It is, perhaps, scarcely necessary to add, that all the suggestions attributed to Brewster and Herschell in the beginning of the hoax, about the “transfusion of artificial light through the focal object of vision,” etc. etc., belong to that species of figurative writing which comes most properly under the head of rigmarole. There is a real and very definite limit to optical discovery among the stars, a limit whose nature need only be stated to be understood. If, indeed, the casting of large [column 2:] lenses were all that is required, the ingenuity of man would ultimately prove equal to the task, and we might have them of any size demanded;* but, unhappily, in proportion to the increase of size in the lens, and consequently of space-penetrating power, is the diminution of light from the object by diffusion of the rays. And for this evil there is no remedy within human reach; for an object is seen by means of that light alone, whether direct or reflected, which proceeds from the object itself. Thus the only artificial light which could avail Mr. Locke would be such as he should be able to throw, not upon “the focal object of vision,” but upon the moon. It has been easily calculated that when the light proceeding from a heavenly body becomes so diffused as to be as weak as the natural light given out by the stars collectively in a clear, moonless night, then the heavenly body for any practical purpose is no longer visible.

The singular blunders to which I have referred being properly understood, we shall have all the better reason for wonder at the prodigious success of the hoax. Not one person in ten discredited it, and (strangest point of all!) the doubters were chiefly those who doubted without being able to say why — the ignorant, those uninformed in astronomy, people who would not believe because the thing was so novel, so entirely “out of the usual way.” A grave professor of mathematics in a Virginian college told me seriously that he had no doubt of the truth of the whole affair! The great effect wrought upon the public mind is referable, first, to the novelty of the idea; secondly, to the fancy-exciting and reason-repressing character of the alleged discoveries; thirdly, to the consummate tact with which the deception was brought forth; fourthly, to the exquisite vraisemblance of the narration. The hoax was circulated to an immense extent, was translated into various languages — was even made the subject of (quizzical) discussion in astronomical societies; drew down upon itself the grave denunciation of Dick, and was, upon the whole, decidedly the greatest hit in the way of sensation — of merely popular sensation — ever made by any similar fiction either in America or in Europe.

Having read the Moon story to an end and found it anticipative of all the main points of my “Hans Phaall,” I suffered the latter to remain unfinished. The chief design in carrying my hero to the moon was to afford him an opportunity of describing the lunar scenery, but I found that he could add very little to the minute and authentic account of Sir John Herschell. The first part of “Hans Phaall,” occupying about eighteen pages of “The Messenger,” embraced merely a journal of the passage between the two orbs and a few words of general [page 162:] observation on the most obvious features of the satellite; the second part will most probably never appear. I did not think it advisable even to bring my voyager back to his parent earth. He remains where I left him, and is still, I believe, “the man in the moon.”

At this point, the only things Mars One is likely to get into orbit are the wheels coming off of the bus

More background on the Mars One story.

From CTV News:
The Dutch non-profit group behind the project recently announced that it was pushing back the planned launch to 2027, due to a lack of funds for a robotic mission that was scheduled to precede the first human launch. The aim of the robotic mission is to test out the technologies required for human survival on Mars.


From NBC:

The Dutch-based Mars One venture is closing in on choosing its crews for one-way trips to the Red Planet, but will they be all dressed up in spacesuits with no place to go? Over the past week, there's been a string of reports that highlight the huge challenges facing Mars One.

Space News reports that the project's leaders haven't followed up on concept studies for robotic missions aimed at sending a lander and an orbiter to Mars in 2018. The Daily Mail says Mars One's deal with Endemol's global TV production team has fizzled out. Meanwhile, the Guardian quotes one of Mars One's initial supporters, astronomer Gerard 't Hooft, as saying the mission "will take quite a bit longer and be quite a bit more expensive" than advertised.

And (better late than never) from NPR:
Still, a Dutch venture called Mars One has captured the public's imagination with its plan to colonize Mars by 2025. Bas Lansdorp, the group's CEO, says they've been featured in major media outlets like CNN and the New York Times. "We've been on NPR — I think twice already," Lansdorp says.
...

"For some reason that I really cannot explain, I wanted to go to Mars and build a new human settlement there," he says.

Lansdorp believes the voyage will likely pay for itself because it will be a media spectacle. Everyone in the world will want to watch the whole adventure, he says. Mars One is planning a reality TV show with sponsorships and advertising.

"We expect it's worth up to 10 Olympic Games' [worth] of media revenue, which is $45 billion," says Lansdorp.

Of course, sponsors of the Olympics can be pretty confident that their games will happen. When asked how he responds to skeptics who say that Mars One is basically just a website and a marketing plan, Lansdorp says, "I think that the people who say that really haven't paid attention to what we've achieved already."
Lots of people applied to be part of the Mars One astronaut corps — paying a fee to do so. And the group has commissioned a couple of studies from established aerospace companies.

The Mars One plan calls for first sending out a small robotic lander in 2018. Lansdorp says he can do this more cheaply than NASA. But missions like that typically cost hundreds of millions of dollars. When told that it didn't sound like he'd raised anything like that amount of money, Lansdorp replied that "we don't need that kind of money yet because we're not yet building the actual lander. But these are the kinds of investments that we're currently in negotiation for."

How much has he raised? He won't say.
