While I was wrapping: Christmas science

December 25, 2009

Ohh, here’s fun:  Photographing fractals using Christmas ornaments, at Evil Mad Scientist Laboratories:

Fractals photographed in three Christmas tree ornaments, Evil Mad Scientist Laboratories

"Construct complex fractals out of light using a few shiny Christmas tree ornaments. Who says the holidays aren't exciting?"

All you need is a camera and some imagination — oh, and some Christmas ornaments. In this case, four silver ornaments ($5 at Target, the guy says), a piece of Scotch tape, and the colored lights.  The photo above comes from four ornaments, stacked.  Go see how he does it (lots of photos), and check out his Flickr stream.

While your kids ponder the pretty lights and stars on the Christmas tree, why not add a little science in?  According to Carlos Hotta, at  Brazillion Thoughts, “The Universe in a Christmas Tree”:

How about looking at the Christmas tree through the light of this knowledge? Here is some food for thought:

  • We know more planets beyond the solar system than there are Christmas balls on your tree. The current count is at 358 exoplanets, and growing;
  • If the planet was [shrunk] to the size of a Christmas ball, it would be the smoothest ball of the tree. The Mount Everest (8 km) or the Marianas Trenchr (11km) are small imperfections relative to the planet’s 12,000 km diameter. It’s an imperfection of less than 0,01%;
  • “Earth is not spherical, it’s an oblate spheroid”, some Grinch may say. Indeed, our planet wider in the equator, but even this deviation from a perfect sphere is of less than 0,04%;
  • If an 8 centimeters Christmas ball represented Earth and the nearest ball represented the nearest known exoplanet – Epsilon Eridani b, 10.5 light-years away – then the distance between them should be around 630,000 km. Almost twice the actual distance from Earth to the Moon. Epsilon Eridani b is quite far from here
  • Now, if the star at the top of the tree represented our Sun, 1,392,000 km in diameter, and the star at the top of your neighbor’s tree – say, 50 meters away – represented the nerest star system, Alpha Centauri at 4 light-years of distance; then the size of our Sun-star to be on the same scale it would have to be 0,74 micrometers large. From 1,4 million kilometers to more than 100 times smaller than the width of a hair, that’s how small the star should be for it to be in the same scale as the distance between it and the neighbor’s Christmas star.

There’s more — plus the original at 100 Nexos (in Portuguese).


Leonid meteor scattered showers

November 18, 2009

Meteors from the Leonid shower could have been good viewing — generally, as I predicted, it was not spectacular.  At least BBC said so.

But if you can make the time, it’s almost always profitable — psychologically and spiritually — to look up at the sky.

Some who did look up got great photographs of the not-spectacular views.

"A fireball seems to shoot right through a house in Grafton, Ontario. Malcolm Park captured the image as he was setting up to photograph meteors on Monday night." (MSNBC caption)

If this isn’t spectacular, can you imagine what would be?


Sputnik at 52

October 5, 2009

Encore post from 2007:

America woke up on October 4, 1957.

The Union of Soviet Socialist Republics (USSR) launched the world’s first artificial satellite into orbit. After successfully putting the shiny ball into orbit, the Soviets trumpeted the news that Sputnik traced the skies over the entire planet, to the shock of most people in the U.S. (Photo of the model in the Smithsonian’s Air & Space Museum in Washington, D.C.)

New Scientist magazine’s website provides significant details about how awake America became, including very good coverage of the Moon landings that were nearly a direct result of Sputnik’s launch — without Sputnik, the U.S. probably wouldn’t have jump started its own space program so, with the creation of NASA and the drive for manned space flight, and without the space race President John F. Kennedy probably wouldn’t have made his dramatic 1961 proposal to put humans on the Moon inside a decade.

Sputnik really did change the world.

Much of the progress to the 1969 Moon landing could not have occurred without the reform of education and science prompted by the Soviets’ triumph. With apathetic parents and the No Child Left Behind Act vexing U.S. education and educators from both sides, more than nostalgia makes one misty-eyed for the National Defense Education Act (NDEA), a direct product of Sputnik-inspired national ambition. Coupled with the GI Bill for veterans of World War II and Korea, NDEA drove U.S. education to be the envy of the world, best in overall achievement (and also drove creationists to try to block such improvements).

(Today NDEA gets little more than a footnote in real historyWikipedia’s entry is short and frustrating, the U.S. Department of Education gives little more. Educators, you have got to tell your history.)

Texas Essential Knowledge and Skills (TEKS) lists 1957 as among the dozen dates students need to know in U.S. history, for Sputnik. It is the only date Texas officials list for U.S. history that is really an accomplishment by another nation. (The first time I encountered this requirement was in a meeting of social studies teachers gearing up for classes starting the following week. The standards mention the years, but not the events; I asked what the event was in 1957 that we were supposed to teach, noting that if it was the Little Rock school integration attempt, there were probably other more memorable events in civil rights. No one mentioned Sputnik. It was more than two weeks before I got confirmation through our district that Sputnik was the historic event intended. Ouch, ouch, ouch!)

Sputnik was big enough news to drive Elvis Presley off the radio, at least briefly, in southern Idaho. My older brothers headed out after dinner to catch a glimpse of the satellite crossing the sky. In those darker times — literally — rural skies offered a couple of meteoroids before anyone spotted Sputnik. But there it was, slowly painting a path across our skies, over the potato fields, over the Snake River, over America.

Sputnik’s launch changed our lives, mostly for the better.

Quote of the moment: John F. Kennedy, “We choose to go to the Moon”

July 24, 2009

John F. Kennedy at Rice University, Houston, Texas, Sept 12, 1962 - photo from NASA

John F. Kennedy at Rice University, Houston, Texas, Sept 12, 1962 – photo from NASA

There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?

We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

President John F. Kennedy, September 12, 1962, at Rice University, Houston, Texas

Why this speech in Houston?  There’s more here than just a speech in a football stadium.  Kennedy was working to save the space initiative, and to make America more secure.

In this quest, Kennedy lays out the reasons we need strong science research programs funded by our federal government, and strong science educational achievement in all of our schools.

From the White House History Association:

Race to the Moon

President John F. Kennedy (1961-1963) awoke on April 12, 1961, to the news that the Soviet Union had won the race to put a man into space. Kennedy immediately met with Vice President Lyndon Johnson in the White House to discuss the embarrassment of the Soviets beating America again. “Can we put a man on the moon before them?” Kennedy asked. A few weeks later, Kennedy challenged the nation to “commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.”

Kennedy challenged Congress and the imaginations of all Americans a few weeks later, when on May 25, in a special Joint Session of Congress, he proposed a Moon exploration program.  In a speech outlining defense and foreign policy needs to make the U.S. secure and safe against threats from Soviet communism, or any other nation or faction, Kennedy spoke openly about the space race that had been waged since October 4, 1957, when the Soviet Union became the first nation on Earth to orbit an artificial satellite, Sputnik.

Kennedy told Congress in that part of the speech:

Finally, if we are to win the battle that is now going on around the world between freedom and tyranny, the dramatic achievements in space which occurred in recent weeks should have made clear to us all, as did the Sputnik in 1957, the impact of this adventure on the minds of men everywhere, who are attempting to make a determination of which road they should take. Since early in my term, our efforts in space have been under review. With the advice of the Vice President, who is Chairman of the National Space Council, we have examined where we are strong and where we are not, where we may succeed and where we may not. Now it is time to take longer strides–time for a great new American enterprise–time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth.

I believe we possess all the resources and talents necessary. But the facts of the matter are that we have never made the national decisions or marshalled the national resources required for such leadership. We have never specified long-range goals on an urgent time schedule, or managed our resources and our time so as to insure their fulfillment.

Recognizing the head start obtained by the Soviets with their large rocket engines, which gives them many months of leadtime, and recognizing the likelihood that they will exploit this lead for some time to come in still more impressive successes, we nevertheless are required to make new efforts on our own. For while we cannot guarantee that we shall one day be first, we can guarantee that any failure to make this effort will make us last. We take an additional risk by making it in full view of the world, but as shown by the feat of astronaut Shepard, this very risk enhances our stature when we are successful. But this is not merely a race. Space is open to us now; and our eagerness to share its meaning is not governed by the efforts of others. We go into space because whatever mankind must undertake, free men must fully share.

I therefore ask the Congress, above and beyond the increases I have earlier requested for space activities, to provide the funds which are needed to meet the following national goals:

First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations–explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon–if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.

(Here’s a link to an audio excerpt of that speech, from the Kennedy Library.)

The race was on.  The Soviet Union’s massive rocket engines gave them a decided advantage.  Kennedy’s challenge captured the imagination of Americans and America.  Necessary money flowed from Congress, but not in a completely free flow.  Some opposed the nation’s efforts in space exploration because they thought spending on space exploration detracted from the nation’s defense efforts.  Kennedy continued to stress the connection between space exploration and defense.  He was backed by successes — Navy Commander Alan Shepard, Jr., had successfully launched into space and returned safely; and on February 20, 1962, pilot Marine Capt. John Glenn orbited the Earth three times, catching the U.S. up almost to where the Soviet Union was in manned space exploration.

Kennedy understood that constant attention, constant selling of the space program would be necessary.  So in September 1962 he found himself in Houston, the newly-designated home of the manned space program, and he took the opportunity to cast the American goals in the space race as peaceful, good for all mankind, and definitely worth the massive costs.

Notice in how he casts putting a human on the Moon in league with other great achievements of civilization.  Kennedy was truly shooting for the stars.

Notice also how he relates space exploration to practical applications then in existence, such as communication, navigation of ships at sea, and weather forecasting.  This was years before geosynchronus satellites were used for everyday telephone conversations, years before quantum theory was harnessed for Global Positioning Systems (GPS) and digital personal, handheld telephones, and before the newly-invented printed circuits were miniaturized to make computer calculating a possibility in space — the Moon landing was done with slide rules and hand calculations.

Just over 14 months later Kennedy would die in Texas, in Dallas, on November 22, 1963.  On July 20, 1969, Neil Armstrong and Buzz Aldrin landed the Eagle Lunar Module on the Moon, at the Sea of Tranquility.  A few hours later, on July 21, they stepped out on the Moon.  From Kennedy’s speech to Congress, the task had taken 8 years, one month and 26 days.

Our nation’s first man in space

July 20, 2009

Our first man in space got there by a route most people can’t guess:  Balloon.

Joe Kittinger recounted his adventures to the CBS Morning Show, how he leaped from a balloon at the edge of space for the Air Force, to prove that humans could survive a fall from such distances, in the event of an emergency that required an astronaut to bail out.

Kittinger bailed out of the balloon at over 102,000 feet, nearly three times the height of Mt. Everest into the atmosphere.

But Elton John never wrote a song about “Balloon Man.”

Great collection of photos from the European Space Agency (ESA), from their Earth from Space: Image of the Week series.  This one is a mosaic of Greece, the Balkans and the Aegean Sea.

Surely this could be made into a bell ringer/warmup.  Check out the images for other geographic forms, and great photos of them.  Nose around the ESA site, there are some great finds.  Can you quickly identify this image, for example (without looking at the name of the photo file)?


When on Earth, Google as the Earthlings do

March 7, 2009

I’m probably way behind the curve, but this looks to me as if it could be developed into a classroom exercise of some sort.

At Geevor Tin Mine Museum’s Weblog, I stumbled onto Whenonge #7 — When on Google Earth #7 (archaeology edition).

These wacky archaeologists!  They get a Google Earth image of some dig, post it, and challenge people to identify the dig and the time in history the site was actually occupied.  The first to identify the site accurately gets to host the next round.

Hey, take a look at these things.  They would make great slides for a presentation, but they’re also just cool.

Mystery image for When on Google Earth #7 (archaeology)

Mystery image for When on Google Earth #7 (archaeology)

Like so much in archaeology, this game comes to us from our methodological cousins in geology. Shawn Graham adopted their game, and modified it for our use at whenonge #1. Chuck Jones had the first correct answer, and then hosted whenonge #2. The mysterious and elusive PDD got #2 right but never claimed his prize, so Chuck struck back with whenonge #2.1. Paul Zimmerman got the correct answer to #2.1 and hosted whenonge # 3. Heather Baker got the correct answer to #3 and hosted whenonge # 4, and Jason Ur won and hosted of whenonge # 5 . Dan Diffendale won that,  #6 was hosted on whenonge #6 and i won this! so here we are… be the first to correctly identify the site above and its major period of occupation in the comments below and you can host your own!

What’s that?  There’s a geology version, too?  Good heavens!  The geologists are past #150!

WoGE #124 - Where on Google Earth #124; I dont know where this is, but it looks cool.

WoGE #124 - Where on Google Earth #124; I don't know where this is, but it looks cool.

It’s the sort of geeky game that airline real estate lawyers could play with airports, football geeks could play with collegiate football stadia, or baseball geeks with Major League Baseball parks.  Hiking, camping and wilderness geeks could do a National Parks and National Monuments version, with real aficianadoes including trails in National Wilderness Areas from the National Forest Service and Bureau of Land Management.

Why not a simple geography version?  Cities with more than 2 million population; national capital cities, state capital cities; Civil War battlefields; famous battlefields; volcanoes; 7 Wonders of the World.

Maybe someone in the Irving, Texas, ISD can get their geography kids to use their computers and put up a website devoted to some of these issues.


Happy Hubble Day! Look up

Today is a good day to celebrate the universe in all it’s glory – December 30. Below, mostly an encore post.

This year for Hubble Day, Wired picked up on the story (with a gracious link to last year’s post here at the Bathtub).  Wired includes several links to even more information, a good source of information.

Hubble was the guy who showed us the universe is not only bigger than we imagined, it’s probably much bigger and much more fantastic than we can imagine. Hubble is the guy who opened our imaginations to the vastness of all creation.

How does one celebrate Hubble Day?  Here are some suggestions:

  • Easier than Christmas cards:  Send a thank-you note to your junior high school science teacher, or whoever it was who inspired your interest in science.  Mrs. Hedburg, Mrs. Andrews, Elizabeth K. Driggs, Herbert Gilbert, Mr. Willis, and Stephen McNeal, thank you.
  • Rearrange your Christmas/Hanukkah/KWANZAA lights in the shape of the Andromeda Galaxy — or in the shape of any of the great photos from the Hubble Telescope (Andromeda Galaxy pictured above; Hubble images here)

    A few of the images from the Hubble Telescope

    A few of the images from the Hubble Telescope

  • Go visit your local science museum; take your kids along – borrow somebody else’s kids if you have to (take them along, too)
  • Spend two hours in your local library, just looking through the books on astronomy and the universe
  • Anybody got a good recipe for a cocktail called “The Hubble?”  “The Andromeda?”  Put it in the comments, please

The encore post, from last year:

December 30, 1924, Edwin Hubble announced the results of his observations of distant objects in space.

PBS

Edwin Hubble - source: PBS

In 1924, he announced the discovery of a Cepheid, or variable star, in the Andromeda Nebulae. Since the work of Henrietta Leavitt had made it possible to calculate the distance to Cepheids, he calculated that this Cepheid was much further away than anyone had thought and that therefore the nebulae was not a gaseous cloud inside our galaxy, like so many nebulae, but in fact, a galaxy of stars just like the Milky Way. Only much further away. Until now, people believed that the only thing existing ouside the Milky Way were the Magellanic Clouds. The Universe was much bigger than had been previously presumed.

Later Hubble noted that the universe demonstrates a “red-shift phenomenon.” The universe is expanding. This led to the idea of an initial expansion event, and the theory eventually known as Big Bang.

Hubble’s life offered several surprises, and firsts:

Hubble was a tall, elegant, athletic, man who at age 30 had an undergraduate degree in astronomy and mathematics, a legal degree as a Rhodes scholar, followed by a PhD in astronomy. He was an attorney in Kentucky (joined its bar in 1913), and had served in WWI, rising to the rank of major. He was bored with law and decided to go back to his studies in astronomy.

In 1919 he began to work at Mt. Wilson Observatory in California, where he would work for the rest of his life. . . .
Hubble wanted to classify the galaxies according to their content, distance, shape, and brightness patterns, and in his observations he made another momentous discovery: By observing redshifts in the light wavelengths emitted by the galaxies, he saw that galaxies were moving away from each other at a rate constant to the distance between them (Hubble’s Law). The further away they were, the faster they receded. This led to the calculation of the point where the expansion began, and confirmation of the big bang theory. Hubble calculated it to be about 2 billion years ago, but more recent estimates have revised that to 20 billion years ago.

An active anti-fascist, Hubble wanted to joined the armed forces again during World War II, but was convinced he could contribute more as a scientist on the homefront. When the 200-inch telescope was completed on Mt. Palomar, Hubble was given the honor of first use. He died in 1953.

“Equipped with his five senses, man explores the universe around him and calls the adventure Science.”

That news on December 30, 1924, didn’t make the first page of the New York Times. The Times carried a small note on February 25, 1925, that Hubble won a $1,000 prize from the American Academy for the Advancement of Science.

(Does anyone have a suitable citation for that video?  Where did it come from?  Who produced it?  Is there more somewhere?)

Happy Hubble Day!  Look up!

Typewriter of the moment: Douglas Adams

July 26, 2008

Here’s a typewriter you can buy. NV Books in Great Wolford, Warwickshire, offers a first edition copy of Douglas Adams’ masterpiece, The Hitch Hiker’s Guide to the Galaxy, together with the autographed typewriter upon which he wrote it:

Douglas Adams's typewriter, a Hermes Standard 8, used to write the novel, The Hitch Hiker's Guide to the Galaxy

Douglas Adams’s typewriter, a Hermes Standard 8, used to write the novel, The Hitch Hiker’s Guide to the Galaxy

It’s yours, for just $25,112.92 (Today. Exchange rates may make the price wobble a bit). Abe Books in Denver lists the advertisement in the U.S.

THE HITCH HIKER’S GUIDE TO THE GALAXY, First Edition in FINE Condition. Sold together with DOUGLAS ADAMS’ TYPEWRITER owned by Adams (whilst writing ‘Hitch Hikers’) and SIGNED IN THICK FELT PEN BY THE AUTHOR across the original casing

Description: First Edition Hardback. A mouthwatering copy of this modern classic, the dustwrapper retains all of the notoriously fugitive blue and is wholly unfaded. The front image and lettering are bright and sharp and the book overall is in exceptional condition. Sold together with A UNIQUE ARTEFACT owned by Douglas Adams in the late 1970s, his Hermes Standard 8 typewriter. This is a thrilling object to possess with a fascinating history. It is as certain as can be that Adams wrote his most famous work ‘The Hitch Hikers Guide To The Galaxy’ on this Hermes Standard 8. Aside from the supporting provenance, it still contains much evidence of his ownership and regular use. It bears an anti-apartheid sticker on one side of the object and is boldly signed across the front casing by Adams in his unmistakeable hand. It comes housed in its cardboard box which Adams used to transport it, namely packaging from Simon and Schuster, originally containing copies of Adams and Terry Jones’ collaboration ‘Starship Titanic’. An address label to Adams’ office at the Digital Village, London, remains stuck on the box too. The typewriter itself is in attractive condition to display, but is entirely unrestored and as precisely as it was when it was owned by Adams. It is frequently mentioned by all who knew him that writing was often a torment for him and as such his lateness was legendary. He once said ‘I love deadlines. I love the whoosing sound they make as they fly by’, and such was his difficulty in producing work on time that in a well-documented act of desperation his publishers once locked him in a hotel room until he typed enough pages to be let out! The keys of his typewriter all still bear the marks of Adams’ tortured labour. Significantly, the ‘x’ key is particularly discoloured. A unique piece of literary history then and a fabulous talking point, and simply the ultimate possession for a Douglas Adams fan. It is almost superfluous to mention that it is also a very secure investment for the future. A little bit about its subsequent history: Adams signed and donated the typewriter to a wildlife charity auction in 1998, and it was then kept in private hands for several years before being sold on. Adams was passionate about wildlife and in keeping with his memory (and his original intention for this item), a donation will be made to Rhino Recovery with this sale. ABOUT US: It is our philosophy at N V to provide the astute collector with high quality books for pleasure and investment, whilst offering a service that is always friendly and helpful.

I can’t improve on Boing Boing’s commentary. Steampunk beat me to the story, too. (The typewriter was sold as a benefit for RHINO by Christie’s on November 30, 2005, for £2,400, about $4,100.)

Your students may not know who Douglas Adams was — Adams died prematurely in 2001, at 49, of a sudden and unexpected heart attack. He was working on the movie adaptation for Hitch Hiker’s Guide.

Hitch Hiker’s Guide started out as a BBC4 radio series, airing in 1978. The book version appeared shortly after that — I think I first read it in 1979, an interim year when I really lit up small corners of Utah. The book was immensely funny, very witty, and self-conscious in a way that most pure humor writing isn’t. Adams appeared to be familiar with science deeply. The jokes work on several levels. The book was popular with friends in public broadcasting who had heard the BBC4 series, and with scientists in laboratories.

One of the NPR stations in Washington, D.C., ran the series shortly after I moved there (WAMU? WETA? I forget which). Use of an Eagles instrumental for the theme caught my ear. Eagles? This series seemed blessed with the best wit, best writing, and best music.

Not so with special effects in the television series. The script was inspired, the narrative effects were fine, but special effects were of the cheesy, early-Dr. Who variety — which was okay, because it put the focus on the script and the story. And the story was the thing.

Through much of that time I was deeply involved in land management issues. We worked on wilderness, the old RARE II wilderness designation process, and segued into the Sagebrush Rebellion, where I found myself deep into rebel territory when the fighting broke out (think of Jackie Vernon’s story of being in Japan when World War II broke out; saying he didn’t really know what to do, he “became a kamikaze copilot”). Hitch Hiker’s Guide opens with Arthur Dent protesting the demolition of his house to make a path for a new thruway, with the authorities telling Dent that he had plenty of time to protest since the notice of demolition was posted in a town only a few miles away, and since he missed the protest period, he shouldn’t complain. He is “rescued” from this situation by a friend named Ford Prefect — like the little European Ford auto — who tells Arthur not to worry about the house; Ford turns out to be an alien, and he knows the Earth is about to be destroyed to make way for an inter-galactic thruway. The destruction crew notes with no irony to the Earthlings that the notice of destruction was posted on a nearby planet, and Earth simply missed the protest period. Ah. A good summary of many land management decisions.

We found comradeship with people who understood that, once a decision had been made, often the best thing to do was remember not to panic, pick up one’s towel and hitch a ride to the next venue. I would not have been much surprised to turn to the appendices of an official BLM report and see that BLM had determined the answer to be “42,” and that a study group had been appointed for further study.

42. 42 is the answer.

The Answer to Life, the Universe, and Everything is numeric in Douglas Adams‘ series The Hitchhiker’s Guide to the Galaxy. In the story, a “simple answer” to The Ultimate Question is requested from the computer Deep Thought, specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer, which turns out to be 42. Unfortunately, The Ultimate Question itself is unknown, suggesting on an allegorical level that it is more important to ask the right questions than to seek definite answers.

Others have wondered about the number.

In the original series, Arthur Dent has a Scrabble™ game with him. At some point it mystically spells out, “What do you get if you multiply six by nine? Forty-two.”

6 times 9 is 42 — except in base-13. But as Adams himself said, he did not write jokes in base-13

I have not seen the movie.

Phoenix has landed

May 25, 2008

Phoenix landed on Mars today at 4:38 p.m. Pacific Time. Confirmation of the landing took 15 minutes to get to Earth, radio signals traveling at the speed of light.

We have a robot scout on Mars again!

This is another of those teachable moments, an event to note in class that your students might tell their children and grandchildren about.

Artist's drawing of Phoenix, on Mars.Touchdown occurred exactly at the time programmed and predicted. Such accuracy might be interpreted as a good sign that NASA has anticipated problems, and a successful mission of discovery is in store.

The University of Arizona leads the discovery consortium on this mission (one of my alma maters). Educational activities and plans for teachers are listed at Arizona’s Phoenix Mission website.

NASA is the world’s biggest player in astrobiology, the science of figuring out how life could have begun, and where it might be. Astrobiology is one of the topics Texas’s State Board of Education threatened to remove from biology texts in 2003. That this mission has gotten this far is a sweet little bit of beneficial revenge on the anti-scientists who tried to gut the books then. Maybe it will pose a warning to them on the next go-round.

Teachers, strike a blow for science, knowledge and leadership in knowledge gathering: Teach your kids some astrobiology.

Carnival catch up: Sputnik at Philosophia Naturalis 14

November 5, 2007

Interesting carnival of natural philosophy that I had not seen before — and Philosophia Naturalis Number 14 celebrates Sputnik. History teachers may want to visit the carnival.

This one is hosted at Dynamics of Cats, one of the Seed Empire science blogs. I regret it took so long to call it to your attention.


Sputnik on newsreel

October 8, 2007

We still had movie newsreels in 1957. ASAP Retro, a part of Associated Press, I think, features the classic Ed Herlihy-announced 30 second explanation of Sputnik that was seen in movie theatres across America in late 1957 and early 1958.

You’ll need a live internet link to use it in class.

I do wish that more of these newsreels were available for easy use by teachers in classrooms, say on DVD, in short segments.


Sputnik’s 50th

October 4, 2007

America woke up on October 4, 1957.

Sputnik, model hanging in Smithsonian Air & Space Museum

The Union of Soviet Socialist Republics (USSR) launched the world’s first artificial satellite into orbit. After successfully putting the shiny ball into orbit, the Soviets trumpeted the news that Sputnik traced the skies over the entire planet, to the shock of most people in the U.S. (Photo of the model in the Smithsonian’s Air & Space Museum in Washington, D.C.)

New Scientist magazine’s website provides significant details about how awake America became, including very good coverage of the Moon landings that were nearly a direct result of Sputnik’s launch — without Sputnik, the U.S. probably wouldn’t have jump started its own space program so, with the creation of NASA and the drive for manned space flight, and without the space race President John F. Kennedy probably wouldn’t have made his dramatic 1961 proposal to put humans on the Moon inside a decade.

Sputnik really did change the world.

Much of the progress to the 1969 Moon landing could not have occurred without the reform of education and science prompted by the Soviets’ triumph. With apathetic parents and the No Child Left Behind Act vexing U.S. education and educators from both sides, more than nostalgia makes one misty-eyed for the National Defense Education Act (NDEA), a direct product of Sputnik-inspired national ambition. Coupled with the GI Bill for veterans of World War II and Korea, NDEA drove U.S. education to be the envy of the world, best in overall achievement (and also drove creationists to try to block such improvements).

(Today NDEA gets little more than a footnote in real historyWikipedia’s entry is short and frustrating, the U.S. Department of Education gives little more. Educators, you have got to tell your history.)

Texas Essential Knowledge and Skills (TEKS) lists 1957 as among the dozen dates students need to know in U.S. history, for Sputnik. It is the only date Texas officials list for U.S. history that is really an accomplishment by another nation. (The first time I encountered this requirement was in a meeting of social studies teachers gearing up for classes starting the following week. The standards mention the years, but not the events; I asked what the event was in 1957 that we were supposed to teach, noting that if it was the Little Rock school integration attempt, there were probably other more memorable events in civil rights. No one mentioned Sputnik. It was more than two weeks before I got confirmation through our district that Sputnik was the historic event intended. Ouch, ouch, ouch!)

Sputnik was big enough news to drive Elvis Presley off the radio, at least briefly, in southern Idaho. My older brothers headed out after dinner to catch a glimpse of the satellite crossing the sky. In those darker times — literally — rural skies offered a couple of meteoroids before anyone spotted Sputnik. But there it was, slowly painting a path across our skies, over the potato fields, over the Snake River, over America.

Sputnik’s launch changed our lives, mostly for the better.

Phil Plait at Bad Astronomy provides a series of links teachers can rely on for good information, especially if you’re composing a lesson plan quickly.

New Scientist’s broad range of coverage of the space race, up to the current drive to go to Mars, is well worth bookmarking.

Humanity’s hope for the future: A giant leap for mankind

July 21, 2007

 

Southwest Elementary in Burley, Idaho, existed in a world far, far away from the U.S. space program. We watched rocket launches on black and white television — the orbital launches were important enough my father let me stay home from school to watch, but when he dropped me off, I was in a tiny band of students who actually made it to school. Potato farmers and the merchants who supported them thought the space program was big, big stuff.

By John Glenn’s flight, a three-orbit extravaganza on February 20, 1962, a television would appear in the main vestibule of the school, or in the auditorium, and we’d all watch. There were very few spitballs. Later that year my family moved to Pleasant Grove, Utah.

Toward the end of the Gemini series, television news networks stopped providing constant coverage. The launch, the splashdown, a space walk or other mission highlight, but the nation didn’t hold its breath so much for every minute of every mission. Barry McGuire would sing about leaving the planet for four days in space (” . . . but when you return, it’s the same old place.”), then six days, but it was just newspaper headlines.

The Apollo 1 fire grabbed the nation’s attention again. Gus Grissom, one of the three who died, was one of the original space titans; death was always a possibility, but the U.S. program had been so lucky. Apollo’s start with tragedy put it back in the headlines.

The space program and its many successes made Americans hopeful, even in that dark decade when the Vietnam War showed the bloody possibilities of the Cold War. That darkest year of 1968 — see the box below — closed nicely with Apollo 8 orbiting the Moon, and the famous Christmas Eve telecast from the three astronauts, Frank Borman, Jim Lovell, and William A. Anders. The space program kept us hopeful.

By early 1969 many of us looked forward to the flight of Apollo 11 schedule for July — the space flight that promised to put people on the Moon for the first time in history, the realization of centuries-old dreams.

But, then I got my assignment for Scouting for the summer — out of nearly 50 nights under the stars, one of the days would include the day of the space walk. Not only was it difficult to get televisions into Maple Dell Scout Camp, a good signal would be virtually impossible. I went to bed knowing the next day I’d miss the chance of a lifetime, to watch the first moon landing and walk.

Just after midnight my sister Annette woke me up. NASA had decided to do the first walk on the Moon shortly after touchdown, at an ungodly hour. I’d be unrested to check Scouts in, but I’d have seen history.

And so it was that on July 20, 1969, Neil Armstrong became the first human to set foot on the Moon: “A small step for a man, a giant leap for mankind,” was what he meant to say in a transmission that was famously garbled (at least he didn’t say anything about jelly doughnuts).

P. Z. Myers says he remembers a lawnmower going somewhere. It must have been very bright in Seattle. (Thanks for the reminder, P.Z., and a tip of the old scrub brush to you.)

2009 will mark the 40th anniversary.

Texas Essential Knowledge and Skills (TEKS) lists 11 dates for U.S. history as the touchstones kids need to have: 1609, the founding of Jamestown; 1776, the Declaration of Independence; 1787, the Constitutional Convention; 1803, the Louisiana Purchase; 1861-1865, the American Civil War; 1877, the end of Reconstruction; 1898, the Spanish American War; 1914-1918, World War I; 1929, the Stock Market Crash and beginning of the Great Depression; 1941-1945, World War II; 1957, the launching of Sputnik by the Soviets. Most teachers add the end of the Cold War, 1981; I usually include Apollo 11 — I think that when space exploration is viewed from a century in the future, manned exploration will be counted greater milestone than orbiting a satellite; my only hesitance on making such a judgment is the utter rejection of such manned exploration after Apollo, which will be posed as a great mystery to future high school students, I think.)

* 1968, in roughly chronological order, produced a series of disasters that would depress the most hopeful of people, including: the Pueblo incident, the B-52 crash in Greenland, the Tet Offensive in Vietnam, the nerve gas leak at the Army’s facility at Dugway, Utah, that killed thousands of sheep, Lyndon Johnson’s pullout from the presidential race with gathering gloom about Vietnam, the Memphis garbage strike, the assassination of Martin Luther King, Jr., riots, the Black Panther shoot out in Oakland, the Columbia University student takeover, the French student strikes, the tornadoes in Iowa and Arkansas on May 15, the Catonsville 9 vandalism of the Selective Service office, the sinking of the submarine U.S.S. Scorpion with all hands, the shooting of Andy Warhol, the assassination of Robert F. Kennedy, the Buenos Aires soccer riot that killed 74 people, the Glenville shoot out in Cleveland, the cynicism of the Republicans and the nomination of Richard Nixon and Spiro Agnew, the Warsaw Pact invasion of Czechoslovakia crushing the “Prague Spring” democratic reforms, the Chicago Democratic Convention and the police riot, the brutal election campaign, the Tlatololco massacre of students in Mexico City, Black Power demonstrations by winning U.S. athletes at the Mexico City Olympics, coup d’etat in Panama. Whew!
