May 22, 1906: Patent to Wright Bros. for “flying machine”

May 23, 2009

In a drawer in a file box in the U.S. Patent Office in Washington, D.C., is a study in black ink on white paper, lines that resemble those images most of us have of the first Wright Bros. flyer, usually dubbed “Kittyhawk” after the place it first took to the air.

The patent was issued on May 22, 1906, to Orville Wright, Patent No. 821393, for a “flying machine.”

It makes more sense if you turn the drawing on its side.

Man the ramparts: Texans, call your legislators!

May 22, 2009

Texans, the information on finding your state representative and state senator are below — call them, today.

In a surprise move, the Senate has moved the nomination of Don McLeroy to the floor for an up-and-down vote.

McLeroy has ushered in a new era of bitter, partisan and divisive politics to the State Board of Education.  In the past year he has insulted English teachers, citizens of Hispanic descent, unnecessarily gutted a good mathematics text from the approved list (just to show he can do it), and done his best to butcher science education standards for Texas.  He suspended work on new social studies curricula because, in part, he doesn’t like the term “capitalism,” insisting on “free enterprise” instead, contrary to almost all scholarly writing on the topic.

The man is a menace to education.  He uses wedge political issues to divide educators from parents, parents from schools, schools from the community, students from teachers, and education from propaganda.

I quote the entirety of the post from Texas Freedom Network’s Insider blog, below, to explain:

UPDATE: Click here to see video of the committee vote.

In a surprise meeting on the Senate floor, the Senate Nominations Committee in Austin has just approved the appointment of Don McLeroy as chairman of the Texas State Board of Education. It appears that McLeroy’s supporters plan to bring his confirmation to the full Senate early next week. Confirmation will require a two-thirds vote.

Committee Chairman Mike Jackson, R-La Porte, had said he would not bring up McLeroy’s confirmation for a vote in committee unless he thought there were enough votes to get it in the full Senate. We don’t know at this point whether opposition from nearly all Democrats and some Republicans has softened, but the signs are alarming.

If you haven’t done so already, it’s critical that you contact your senator and tell him or her that you oppose McLeroy’s confirmation. You can find the name and contact information for your senator here.

Texas Freedom Network President Kathy Miller has released the following statement:

“If the Texas Senate genuinely cares about quality public education, they will reject as state board chairman a man who apparently agrees that parents who want to teach their kids about evolution are monsters. And we’ll see whether senators really want a chairman who presides over a board that is so focused on ‘culture war’ battles that it has made Texas look like an educational backwater to the rest of the country.”

Gov. Perry appointed McLeroy board chairman in July 2007. Since then, the board has turned debates over language arts and science curriculum standards in “culture war” battlegrounds. Chairman McLeroy has also endorsed a book that says parents who want to teach children about evolution are “monsters” and calls clergy who see no conflict between faith and science “morons.” This spring McLeroy led other creationists on the state board in adopting new science curriculum standards that call the scientific consensus on evolution into question and no longer include references to scientific estimates of the age of the universe.


Ida, our only Darwinius masillae: Are we a lemur’s nephews and neices?

May 22, 2009

She’s being called Ida (EE-duh, to the Brits, EYE-duh to Bob Wills fans).  How could you miss all the hype about her unveiling this week?

Science fans complain that the hype might be over done.  Creationists appear a bit panicked by the developments.

Ida herself?  She’s beautiful.  Here’s an interview with Michael Novacek from the American Museum of Natural History in New York, carried on the public television news program World Focus.

Here’s a collection of British television stories on Ida, including David Attenborough’s animation of the reconstruction of her skeleton — some great graphics:

Evolution 2009, in Kearney, Nebraska

May 20, 2009

Evolution 2009 kicks off Wednesday, September 2, 2009 at the University of Nebraska atKearney.

In honor of Darwin’s birth bicentennial and the sesquicentennial of his most famous work, the program is dedicated to evolution in different fields of biology.

High school instructors can get in for $75.  World class scientists like Jack Horner, Brad Davidson, Shannon Williamson and Randy Moore will present — along with world class evolution and legal evidence expert, Nick Matzke.

The main hotel will be the Ramada Inn in Kearney, where I spent a cold, snowy night in November 1979 after a kindly truck driver from Consolidated Freightways rescued me from certain hypothermia a few miles out of town, where my car had spun into nearly six feet of snow.

Now, can I find some excuse to get to the conference?

I predict:  For the 21st consecutive year since the field of intelligent design was proposed, there will be no new research supporting intelligent design, even in the poster sessions.  This is a science conference, and intelligent design supporters will quietly boycott the entire affair.


Bell Ringer: Bermuda Triangle, Area 51, Marfa, and other cool mysteries

May 17, 2009

If a day goes by that I don’t get a question about one of these sites, it’s a very slow day.

Those questions tell me something else:  Students have genuine interests in geography, and in mysteries.  Students will pay attention to lesson plans that include one or more of these sites in them, especially if you refer to the mystery.

How about just a geography search:  How close is the closest site to you?  Can students visit these sites on their summer vacations?  What airport is closest for tourists?  What arrangements need to be made to visit the place?

Wired.com provides the video — your students have the questions.  Can you provide the answers, or lead them to the answers?  How about listing your answers in comments?

Using evolutionary science to fight fire ants

May 17, 2009

No real Texan would ever entertain the slightest doubt about the accuracy of evolution theory, once that Texan understood how evolution helps fight the imported Argentine fire ant, Solenopsis invictaAnd, who could invent flies that turn the tiny ants into zombies as their larva eat the brains of the ants?

Evolution theory suggests that predators, or at least a parasite, exists for almost every species on Earth.  Fire ants, though seemingly invincible (hence the species name, invicta), also have predators and parasites.  Control of the ants may be a function of finding the right natural enemy of the ant.

Bill Hannah reduces the science to a good lay explanation in the Fort Worth Star-Telegram:

It sounds like something out of science fiction: zombie fire ants. But it’s all too real.

Fire ants wander aimlessly away from the mound.

Eventually their heads fall off, and they die.

The strange part is that researchers at the University of Texas at Austin and Texas A&M’s AgriLife Extension Service say making “zombies” out of fire ants is a good thing.

“It’s a tool — they’re not going to completely wipe out the fire ant, but it’s a way to control their population,” said Scott Ludwig, an integrated pest management specialist with the AgriLife Extension Service in Overton, in East Texas.

The tool is the tiny phorid fly, native to a region of South America where the fire ants in Texas originated. Researchers have learned that there are as many as 23 phorid species along with pathogens that attack fire ants to keep their population and movements under control.

Cartoons: Bill Mauldin on DDT

May 16, 2009

Bill Mauldin rose to fame drawing cartoons from the fronts during World War II, first as a soldier, and then as the cartoonist for Stars and Stripes.  He won the Pulitzer Prize for cartooning in 1945.  After the war he continued to be a major force in American culture, eventually cartooning for the St. Louis Post-Dispatch and quickly winning a second Pulitzer, and then with the Chicago Sun-Times, with drawings syndicated to other newspapers around the world.

In 1962 Mauldin turned his pen to DDT and the controversy created in part by Rachel Carson’s best-selling book Silent Spring.

History: May 15, 1963, President’s council vindicates Rachel Carson, warns of pesticide dangers

May 15, 2009

President John F. Kennedy’s Science Advisory Council (PSAC) studied Rachel Carson’s best-selling book, Silent Spring, checking it for scientific accuracy.  Kennedy read the book himself, but sought expert advice before doing anything.  Meanwhile, DDT manufacturers bankrolled an extensive public relations campaign claiming DDT was safe, and suggesting Carson was less than a careful writer and scientist.

On May 15, 1963, PSAC reported:  Carson was right. Pesticides were being misused, even abused, and some pesticides like DDT presented significant threats to the environment.  “The Use of Pesticides” recommended increased government scrutiny of the safety and efficacy of pesticides, and vindicated Carson’s reporting of science findings.

Library of Congress described the event and its import in America’s Library, “Meet Amazing Americans”:

The Consequences of Silent Spring

Reading Carson’s book changed many people’s ideas about the environment and inspired some to take action. People wrote to their representatives in congress and asked them to do something about the misuse of pesticides. When several senators created a committee to research environmental dangers, they asked Carson to speak to them about pesticides. Carson recommended that the government regulate and reduce pesticide use, and that it ban the most toxic pesticides. She said that a citizen of the United States had the right “to be secure in his own home against the intrusion of poisons applied by other persons.”

President Kennedy understood the importance of Carson’s book. He asked his Science Advisory Committee to research Carson’s claims in Silent Spring. In 1963 the Committee released a report called “The Uses of Pesticides.” It supported Silent Spring. Environmental activists continued to push the government to regulate pesticides. Changes in federal law in 1964 required companies to prove that something did not cause harm before they could sell it. In 1972, activists pushed for and won a ban on DDT, the pesticide that started Carson’s research for Silent Spring. And in 1970 the Environmental Protection Agency (EPA) was created “in response to the growing public demand for cleaner water, air and land.” Who knows what the world would be like today if Rachel Carson had not written Silent Spring?

 
Some radicals argue that Rachel Carson’s legacy is tarnished, that she was in error about DDT, and somehow that translates into many deaths as a result of malaria, as if DDT worked against malaria parasites themselves.  With such a strong propaganda campaign of disinformation plaguing us today, we do well to pause and remember that Carson’s work was subjected to intense, careful scrutiny by scientists from the start.  Carson’s reporting was accurate, and her legacy of environmental protection and saving lives should be celebrated.

History: May 15, 1953 and the mysteries of life’s beginnings

May 15, 2009

May 15, 1953, saw the publication in Science of Stanley Miller’s dramatic experiment showing that essential chemicals of life rise spontaneously.

As usual, the real history is better and much more serendipitous than anyone could imagine in a fictional account; here’s an account from the International Astrobiology Society (ISSOL), from their 2003 celebration of the 50th anniversary of Miller’s paper’s publication:

The University of Chicago Chemistry Department seminars were held on Mondays in Kent Hall, an old building where the floors creaked and there was a smell of dust and mildew. Only the most distinguished scientists were invited to speak at this seminar, many had Nobel prizes or were to receive one, and the list included Franck, Urey, Calvin, Seaborg, Eigen, Libby and Taube.

But this day was different because a second year graduate student, Stanley Lloyd Miller, was speaking, and the room was full because the word had spread that something important was to be presented. In addition to the famous scientists and less famous but equally high-powered scientists was an undergraduate, Carl Sagan attending his first chemistry seminar. The topic was the synthesis of important biological compounds, using conditions thought to have existed on the primitive Earth.

Miller reported that by sending repeated electric sparks through a sealed flask containing a mixture of methane, ammonia, hydrogen, and water vapor, he had made some of the amino acids found in proteins. Perhaps, he suggested, this was how organic compounds were made on the ancient Earth before life existed.

While Miller was confident of his results, the rows of famous faces in his audience were, to say the least, intimidating. He was bombarded with questions. Were the analyses done correctly? Could there have been contamination? After the event, Miller thought that the questions had been constructive, but since the results were hard to believe, they had simply wanted to ensure that he had not made some mistake. However, Carl Sagan thought that Miller’s inquisitors seemed to be picky and did not appreciate the significance of the experiment. Even the relevance of Miller’s results to the origin of life were questioned. When someone asked Miller how he could really be sure this kind of process actually took place on the primitive Earth, Nobel Laureate Harold Urey, Miller’s research advisor, immediately interrupted, replying, “If God did not do it this way, then he missed a good bet.” The seminar ended amid the laughter, and the attendees filed out with some making complimentary remarks to Miller. Miller changed clothes, went back to the lab and started a paper chromatography run.

The events leading up to this dramatic seminar began two years earlier in October, 1951 when Urey presented the Chemistry Department seminar on the origin of the Solar system. In addition to the usual high powered scientists, the audience had contained the then first year graduate student, Stanley Miller.

Read “Prebiotic Soup—Revisiting the Miller Experiment” by Jeffrey Bada and Antonio Lazcano published in Science300 (2003) 745-726 in full text or as a PDF.

This is an abridged version of the Stanley Miller’s 70th Birthday published in Origins of Life and Evolution of the Biosphere 30: 107-112, 2000 by Jeffrey Bada and Antonio Lazcano and The Spark of Life – Darwin and the Primeval Soup by Christopher Wills and Jeffrey Bada, Perseus Books, 2000.

More than 50 years ago scientists demonstrated that basic chemicals of life, thought previously by some to be too complex to arise naturally, could occur in nature spontaneously. Much of the misunderstanding and crank science behind creationism is devoted to hiding these facts.

Lift a glass to Stanley Miller and his experiment today, a toast to learning, a toast to the truth.

Lock up your children and diplomas: Texas Lege still festering

May 14, 2009

In Austin, the Texas Lege stumbles on.  No man’s life, liberty, etc.

Steve Schafersman writing at his new blog, Geo.Sphere, gives details probably available nowhere else on bills to overhaul Texas education again, again.

House Bill 3 and Senate Bill 3, the two identical bills being considered in the Legislature now that will change Texas education laws for student assessment, tracking, documentation, and accountability, also affect high school graduation requirements. Unfortunately, anti-education lobbyists have been very successful and the HB3-SB3 bill as currently written delays the implementation of the 4×4 high school curriculum for many years. This will have a very deleterious effect on Texas science and math education, college readiness, allow continuation of the senior-year math and science layoff, and remove the need for a variety of 12th-grade capstone science and math courses.

Yes, you need to call your Texas representatives.  Schafersman gives the numbers.  Drop by his new blog, get details, get on the phone.

Of course you know, Schafersman is also the head of Texas Citizens for Science.

A different view of the California creationism in the classroom decision

May 10, 2009

Wired takes a different view of the California case in which an AP history teacher was found to have violated a student’s rights with comments about creationists — at least, different from the view I’ve articulated here.  It’s worth a look — and it shows that this case needs to be evaluated more carefully and closely.  Alexis Madrigal wrote at Wired’s website:

The teacher got into hot water because the creationism statement came outside the context of his AP European History class. In making the statement during a discussion of another teacher’s views on evolution, the court could not find any “legitimate secular purpose in [the] statement.”

However, Judge Selna found a second statement that Corbett made about creationism did not violate the student’s First Amendment rights, although it’s an equally pointed critique.

“Contrast that with creationists,” Corbett told his class. “They never try to disprove creationism. They’re all running around trying to prove it. That’s deduction. It’s not science. Scientifically, it’s nonsense.”

That statement was OK because it came in the context of a discussion of the history of ideas and religion. Thus, its primary purpose wasn’t just to express “affirmative disapproval” of religion, but rather to make the point that “generally accepted scientific principles do not logically lead to the theory of creationism.” One might expect that if creationism came up in the context of evolutionary biology, it would be similarly OK to say, “Scientifically, it’s nonsense.”

The nuanced decision prompted the judge to append an afterword. Selna explains his thinking a basic right is at issue, namely, “to be free of a government that directly expresses approval of religion.” Just as the government shouldn’t promote religion, he writes, the government shouldn’t actively disapprove of religion either.

It seems to me, still, that the instructor was well within legal bounds.  For example, we would not ask a biology instructor to pay deference to the Christian Science view that disease is caused by falling away from God (sin), and not by germs, and consequently that prayer is effective therapy.  As a pragmatic matter, Christian Scientists don’t demand that everybody else bow to their view; but in a legal suit, the evidence of Pasteur’s work and subsequent work on how microbes cause disease would trump any claim that Pasteur was “not religiously neutral.”

We still await word on whether the district and teacher will appeal the decision.


Climate Denial Crock of the Week: Ocean levels

May 10, 2009

Blue Ollie carried a YouTube video that got me to look at Peter Sinclair’s marvelous series of amateur videos, “Climate Denial Crock of the Week.” Sinclair posts under the handle GreenMan at YouTube.

Here’s the Climate Denial Crock of the Week video on ocean levels, and the denial that they are rising — in line with my post a few hours ago about peoples in the South Pacific and in Alaska losing their homes to climate change:

Pat Frank’s work keeps reminding us that, in science, it’s often difficult to establish a clear, indisputable proximate cause.  Something is going on in Newtok, Alaska, and in the Carteret Islands, Papua New Guinea.  Those things should not be ignored, and cannot be ignored safely for long.

(Teachers:  Note most of these videos are around 5 minutes in length — more than suitable for classroom use, perhaps even as a bell ringer.  Notice also that, if you don’t know how to make these videos, as I don’t, you’re behind the curve.)

What if we changed the climate and no one paid attention?

May 10, 2009

Rush Limbaugh, Pete DuPont, Michael Savage, the Discovery Institute and other great exponents of reality denial (generally, but not always, without drugs) will continue to rail at James Hansen’s science chops, but the universe goes on in the Real World™Global warming, climate change, takes a severe toll on inhabitants of this planet.

It’s a tribute to the propaganda value of Anthony Watts that this milestone earned so little note:  Residents of Carteret Island, Papua New Guinea, began their move to higher ground last week. The rising ocean is reclaiming their land; seasonal high tides make agriculture impossible.

Who noticed?

You can read about the refugees in The Solomon Times.  You can read about it in the Papua New Guinea Post -Courier. You can’t read it about it much of anywhere else.  The revolution is not televised, it’s not even in print.

Meanwhile, in Alaska, without serious action by the world to enact some sort of program out of the Kyoto meetings to combat climate change by nations united, indigenous peoples are meeting to figure out what they can do without government help.  The place of their meeting carries a message:

The summit is taking place about 500 miles from the Alaskan village of Newtok, where intensifying river flow and melting permafrost are forcing 320 residents to resettle on a higher site some 9 miles away in a new consequence of climate change, known as climigration.

Newtok is the first official Arctic casualty of climate change. A U.S. Army Corps of Engineers study indicates 26 other Alaskan villages are in immediate danger, with an additional 60 considered under threat in the next decade, Cochran said.

Here’s how the warming denialists’ diary entries should run:

“Climate change chased the Carteret Islanders out of their homes, but I wasn’t concerned because I am not a Carteret Islander, and probably couldn’t find the place on a map.”
