Is your science class as smart as a U-Haul truck?

October 23, 2013

We had to fight to keep this stuff in Texas science books.

Then, out on the street, I see a U-Haul truck.

U-Haul truck features geographic information, and geology information

U-Haul truck features geographic information, and geology information, about Arkansas and its Crater of Diamonds State Park.

Detail:  U-Haul truck features a graphic description of the geology and information about Arkansas's Crater of Diamonds State Park.

Well played, U-Haul.  Can Texas catch up?

Update, October 24, 2013:  Turns out U-Haul has a website that features all of the graphics they use on their trucks.  I sense a geography or state history assignment in here, somewhere, social studies teachers.  Reminds me of the animals that used to (still do?) grace the tails of Frontier Airlines airplanes, the Native American on the tails of Alaska Airlines, and other specific destination promoting tricks businesses have used over the years.  Wish more businesses would do that.

No, the evidence doesn’t point to a Noachic flood.  Evidence contradicts the idea.

What rocks Yosemite? Granite

July 7, 2013

Yosemite’s Nature Notes #20 (I’m behind):  A short film discussing the astonishing manifestations of granite in Yosemite National Park.

English: El Capitan in Yosemite National Park ...

The film is simply named, “Granite.”  Steven Bumgardner produced the film.

Yosemite’s chief formations are granite, an igneous rock.  Much of the terrain was carved in the granite by glaciers and glaciation — so what Yosemite shows is how fire and ice combine to make rock, to make rock formations, and to make rocks of astonishing beauty.

(This is not a place to bolster creationist ideas.  This is real science, looking at God’s handiwork first hand.)

A North Carolina university makes field trips to Yosemite?  I’d love to take that class!

Watching this film, you get a sense of how important it can be to the education of our children to travel in the summers, to take vacations to our National Parks, and to places like Yosemite.

Where are you taking your kids this summer?  Kids, where are you going?

Enjoy it.  Geology lessons are often fun, and this one, on film, is more fun than most.

Darwin’s death, April 19, 1882

April 20, 2013

We shouldn’t get out of April 19 — a day marked by significant historic events through the past couple hundred years — without remembering that it is also the anniversary of the death of Darwin.

Charles Darwin in 1881, by John Collier

Immortality?  Regardless Darwin’s religious beliefs (I’ll argue he remained Christian, thank you, if you wish to argue), he achieved immortality solely on the strength of his brilliant work in science. Of course he’s best known for being the first to figure out that natural and sexual selection worked as tools to sculpt species over time, a theory whose announcement he shared with Alfred Russel Wallace, who independently arrived at almost exactly the same theory but without the deep evidentiary backup Darwin had amassed.

But had evolution turned out to be a bum theory, Darwin’s other works would have qualified him as one of the greatest scientists of all time, including:

  • World’s greatest collector of biological samples:  During his five years’ voyage on HMS Beagle, Darwin collected the largest collection of diverse plant and animal life ever by one person (I believe the record still stands); solely on the strength of his providing actual examples to the British Museum of so much life in so many different ecosystems worldwide, before he was 30 Darwin won election to the Royal Society.  (His election was engineered partly by friends who wanted to make sure he stayed in science, and didn’t follow through on his earlier plan to become a preacher.)
  • Geology puzzle solver:  Coral atolls remained a great geological mystery.  Sampling showed coral foundations well below 50 feet deep, a usual limit for coral growth.  In some cased old, dead coral were hundreds of feet deep.  In the South Pacific, Darwin looked at a number of coral atolls, marvelous “islands” that form almost perfectly circular lagoons.  Inspired partly by Lyell’s new encyclopedic review of  world geology, Darwin realized that the atolls he saw were the peaks of volcanic mounts.  Darwin hypothesized that the volcanoes grew from the ocean floor to the surface, and then the islands were colonized by corals.  The round shape of the volcano gave the atoll its shape.  Then the volcanic mounts eroded back, or sank down, and corals continued to grow on the old foundations.  It was a perfectly workable, natural explanation for a long-standing geologic puzzle.  (See Darwin’s monograph, Structure and Distribution of Coral Reefs.)
  • Patient watcher of flowers:  Another great mystery, this time in biology, concerned how vines twined themselves onto other plants, rocks and structures.  Darwin’s genius in designing experiments shone here:  He put a vine in his study, and watched it.  Over several hours, he observed vine tendrils flailing around, until they latched on to something, and then the circular flailing motion wrapped the tendril around a stick or twig. Simple observation, but no one had ever attempted it before.  (See On the Movements and Habits of Climbing Plants.)
  • Champion of earthworms, and leaf mould:  Darwin suspected the high fertilizer value of “leaf mould” might be related to the action of earthworms.  Again, through well-designed experiments and simple observation, Darwin demonstrated that worms moved and aerated soil, and converted organic matter into even richer fertilizer. (See The Formation of Vegetable Moulds Through the Action of Worms.)
  • Creation of methodological science:  In all of this work, Darwin explained his processes for designing experiments, and controls, and made almost as many notes on how to observe things, as the observations themselves.  Probably more than any other single man, Darwin invented and demonstrated the use of a series of processes we now call “the scientific method.”  He invented modern science.

Any of those accomplishments would have been a career-capping work for a scientist.  Darwin’s mountains of work still form foundations of geology and biology, and are touchstones for genetics.

Born within a few hours of Abraham Lincoln on February 12, 1809, Darwin survived 17 years longer — 17 extremely productive years.  Ill through much of his life with mystery ailments, perhaps Chaga’s Disease, or perhaps some other odd parasite or virus he picked up on his world travels, Darwin succumbed to heart disease on April 19, 1882.

How’s the NRA going to spin this one?

Psy got more than 7 billion views on one video.  Can you help Sesame Street get to one billion, total?  It’s a better cause.  And it may frost the heck out of Sal Khan, too.

Sesame Street actually has a lot of video up for YouTube use — that is, for your use.  This is one of the most important educational sites on the entire internet. 992,469,603 total views at this moment.

Whose educational video works best, Sal Khan’s or Cookie Monsters?

U.S. Rep. Marsha Blackburn, R-Tennessee, said she doesn’t think we need an increase in the minimum wage, especially not to the $9 level President Obama asked.  She said her $2.15 minimum wage was enough . . .

Oops:

At that time, the minimum wage was $1.60, equivalent to $10.56 in today’s terms. Today’s minimum wage is equivalent to just $1.10 an hour in 1968 dollars, meaning the teenage Blackburn managed to enter the workforce making almost double the wage she now says is keeping teenagers out of the workforce.

Do Republicans ever learn history, or make the minor mathematical calculations to adjust for historic inflation?  Pretty tough to flunk history, math and economics in such a short statement.

Is there a rational reason that Wisconsin Rep. Paul Ryan’s  solutions to U.S. problems always involve economic pain to others?  Will cuts in food and health care make these 600,000 children smarter, too?

Here you go, Mittens in winter:

The Mittens in winter, by Howard Noel, via National Wildlife Federation

Caption from the National Wildlife Federation: Howard Noel’s photo of Monument Valley captures the East and West Mitten Buttes, as well as Merrick’s Butte on the right. These natural sandstone and shale structures are just a few of the world-famous geological features in Monument Valley Navajo Tribal Park, located along the Arizona-Utah state line within the Navajo Nation Reservation. The Utah resident used a Canon EOS 5D Mark II camera and a 24-105mm lens.

Where in Utah does Howard Noel hail from?  While I’ve been by these formations in winter, it was never with a camera to catch the snow.  This park is an ideal place to spend a couple of days learning landscape photography, if you’re looking for a place to try out your new camera.  Great place to be anytime, for me.

Hey, if you’re planning drive to see the Mittens, you should be aware that part of Highway 89 is out of commission due to a slump off the roadway between Flagstaff and Page, Arizona — the Navajo Reservation being as large as it is, and as unroaded as it is, when a main road goes out, detours can be spectacularly long.   Earthly Musings carries geological explanations, history and great photos.  How much detour?  This one requires a job to the east, through Tuba City, probably adding about an hour to the trip between those two cities.

The Arizona Department of Transportation says traffic will detour around the closure by using U.S. 160 and State Route 98, adding 45 miles of driving. (emphasis added here)

Meanwhile, in the rest of America? This is okay.  America is ashamed of Rush Limbaugh’s ranting, too.  Fair, no?

Why was the death toll so high in season 3 of “Downton Abbey?”  Writer Julian Fellowes explained it’s a kind of contract issue — anti-regulation types will no doubt crawl out of the woodwork to complain about government interference in the right of contract in English theatre.


Time machine! For Digital Learning Day

Screen shot from HHMI’s iPad app, Earth Viewer — the time machine function.

Stealing the entire post from P. Z. Myers at Pharyngula:

I’ve been playing with it for a while. It turns out that when you go back to Cretaceous Morris, you need to be able to swim really well, but Cambrian Morris is high and dry on a fairly small landmass (whoa, but oxygen is way down and carbon dioxide way up). You can have your own time machine, too — it’s the EarthViewer app for iPad, and it’s free from HHMI Here’s what it has:

• Data and continental reconstructions dating back billions of years

• Climate and carbon dioxide data for the last 100 years

• The ability to manipulate the globe and zoom to any location

• Track the location of modern cities back over 500 million years

• In depth features on major geological and biological events in Earth history

• Clickable details on geologic eons, eras, and periods

• Automated play modes

• An extensive reference list

• Suggestions for classroom use

• Tutorial videos

Did I mention that it’s free? This HHMI thing is pretty danged sweet.

There is no creationist/Noah’s Flood version.

No Windows version, yet, either.

Did we mention the Howard Hughes Medical Institute made this and related apps free?
