China-Olympics-sized stakes in science education

August 25, 2008

Frank Rich, in Sunday’s New York Times:

We don’t have the time or resources to go off on more quixotic military missions or to indulge in culture wars. (In China, they’re too busy exploiting scientific advances for competitive advantage to reopen settled debates about Darwin.) Americans must band together for change before the new century leaves us completely behind.

It’s an aside in a longer piece of advice to Obama on issues for the rest of the campaign.  It’s a Sputnik statement for this century, for anyone with the brains to pay attention.


Dangers of failing to teach evolution, part I

August 24, 2008

From comments at the website of the New York Times today, on the story, “A Teacher on the Front Line as Faith and Science Clash”:

I teach biology and I would like to add a story in encouragement to other biology teachers. About 15 years ago I was teaching a botany course to college sophomores and started discussing the evolution of land plants. Expressions began to harden. Students stopped taking notes. So I stopped and asked if my discussion of evolution was bothering them. Many nodded and one said, “Why do teachers act like evolution is a fact?” At the time I had little experience and had assumed they had a working knowledge of evolution from previous classes at college as well as from high school biology. They did not. I didn’t have much time left that day, but I did explain some of the lines of evidence that support evolution.

The next day, one of my students came in and slammed a stack of books onto her table. She said, “I am so mad! I am so angry!” She looked near tears. She said, “My parents never let me even hear the word, evolution! They said it was all lies! I went to the library last night and got out books about it!” (and here she held up Origin of Species) Then she said, “It makes so much SENSE! I am so angry I never got to learn about it before!”
Now I teach a class entirely about evolution and I think of her often. She still gives me inspiration to keep on trying to open up minds.

Read this: Teaching science is hard, made harder by religious claptrap

August 24, 2008

Page A1 of the New York Times on Sunday, August 24, 2008: “A Teacher on the Front Line as Faith and Science Clash.

Read it, and consider these questions:

  1. Would your local paper have the guts to report on this issue, for your local schools? (The Times went to Florida; heaven knows few Florida papers could cover the issue in Florida so well.)
  2. What is your local school board doing to support science education, especially for evolution, in your town? Or is your local school board making it harder for teachers to do their jobs?
  3. What is your state education authority doing to support science education, especially in evolution, in your state? Or is your state school board working to make it harder for teachers to do their jobs, and working to dumb down America’s kids?
  4. Do your school authorities know that they bet against your students when they short evolution, because knowledge about evolution is required for 25% of the AP biology test, and is useful for boosting scores on the SAT and ACT?
  5. Does your state science test test evolution?
  6. Do your school authorities understand they are throwing away taxpayer dollars when they encourage the teaching of voodoo science, like intelligent design?

It takes a good paper like the Times to lay it on the line:

The Dover decision in December of that year [2005] dealt a blow to “intelligent design,” which posits that life is too complex to be explained by evolution alone, and has been widely promoted by religious advocates since the Supreme Court’s 1987 ban on creationism in public schools. The federal judge in the case called the doctrine “creationism re-labeled,” and found the Dover school board had violated the constitutional separation of church and state by requiring teachers to mention it. The school district paid $1 million in legal costs.

That hasn’t slowed the Texas State Board of Education’s rush to get the state entangled in litigation over putting religious dogma in place of science. The Texas Education Agency (TEA) is already embroiled in one suit, brought by the science-promoting science curriculum expert they fired for noting in an e-mail that science historian Barbara Forrest was speaking in a public event in Austin. TEA may well lose this case, and their side is not helped when State Board Chairman Don McLeroy cavorts with creationists in a session teaching illegal classroom tactics to teachers. Clearly Texas education officials are not reading the newspapers, the court decisions, or the science books.

Here’s one of the charts accompanied the article. While you read it, consider these items: The top 10% of science students in China outnumber all the science students in the U.S.; the U.S. last year graduated more engineers from foreign countries than from the U.S.; the largest portion were from China. China graduated several times the number of engineers the U.S. did, and almost all of them were from China.

Can we afford to dumb down any part of our science curriculum, for any reason? Is it unfair to consider creationism advocates, including intelligent design advocates, as “surrender monkeys in the trade and education wars with China?”

A Texas riddle indeed: Why is McLeroy hanging with creationists?

August 21, 2008

Here’s the post from über creationist Ken Ham’s site, in its entirety:

A Texas Riddle

Last week, AiG speaker Mike Riddle did a series of talks in Brenham, Texas. On the first day, Mike did four different sessions for 1st–6th graders. He usually speaks to young people on topics like “The Riddle of the Dinosaurs,” AiG’s well-known “7C’s of History,” and fossils.

image001.jpg

On the next day, Mike did four special sessions for teachers. Each presentation was geared to help instructors be better prepared to teach origins in the public schools. In addition to speaking on what creationists believe, he spoke on understanding presuppositions and assumptions in the origins debate–and using critical thinking skills. Mike also had the opportunity to meet with the Chairman of the Texas State School Board, Don McLeroy (a biblical creationist), and gave presentations to an open audience at the Brenham High School auditorium.

image003.jpg

Mike and Don McLeroy (Chairman, Texas State School Board)

“Special sessions for teachers?” Oy vey.

1. I’ll wager, if those were real, public school teachers, they were given continuing education credits for attending. That would be illegal, especially if Riddle did not preface his presentations with a legal disclaimer that what he urges is contrary to Texas science standards and contrary to the Constitution. Want to wager whether he did?

2. What’s McLeroy doing there? Doesn’t he know he’s supposed to maintain antiseptic separation from such controversial stuff? They fire people from the TEA for attending sessions that are legal and support the Texas standards. What sort of Quisling action is this on McLeroy’s part?

3. Is Rick Perry watching? The state’s legal fees will rise dramatically as a result of this kind of bad judgment at the SBOE. Can Texas taxpayers afford this?

4. Why does Don McLeroy hate Texas’s smarter, college-bound children so?

It takes a particular form of chutzpah to stand idly by while qualified science teachers are fired from the state’s education agency for promoting science, and then go cavort with creationists. It may not be cowardice exactly, but courage is its antonym.


Climate change skeptics, your Freudian slip is showing

August 21, 2008

Is the climate change debate about science, or politics?

Anthony Watts’s blog settled the question yesterday. Watts has been conducting surveys of U.S. weather reporting stations in a months-long campaign to make a case that data have been skewed by inappropriate sitings of the measuring equipment. Other posts on the blog celebrate every release of information that might be construed as contrary to warming or contrary to human effects on climate, or denigrating any release that supports a claim of change or that human activities cause the change.

The U.S. Climate Change Science Program released a draft report for public comment several weeks ago. Watts criticized the report for a tone he interpreted as advocacy instead of science. Since comments on the report are wide open, as required under the Administrative Procedures Act, comments like Watts’ can be submitted to the agency, and they must be answered. Watts’ invitation to people who disagree with any part of the report is a good encouragement for people to take a part in this important debate about public policy.

But then, yesterday, Watts posted the smoking gun showing political pushing of the science from the White House, unintentionally, I’m sure. In fact, Watts hailed the thing, with a headline claiming that the report was being “pulled.”

Reading through Watts’s post it is difficult to figure out what happened that prompted the headline — it’s hidden away in his quote of the attack-dog propaganda site at National Review On-line, Watts said:

Chris Horner writes on NRO Planet Gore:

…the U.S. Chamber pointed out that a preponderance of the 21 reports that had purportedly been “synthesized” had not actually been produced yet. Sure, that sequence sounds odd in the real world, but is reminiscent of the IPCC, to which the USP appealed as the authority for certain otherwise unsupported claims (though the IPCC openly admits that it, too, performs no scientific research). This is a point we also made in our comments. I’m informed that NOAA has now agreed to publish the underlying documents first and then put out their desired USP. The Chamber should have a release out soon.

Did you catch that? It’s in the line, “NOAA has now agreed.” So what is the document at NOAA referred to?

Oh, it’s not a document from NOAA. It is a memorandum from the anti-climate change science group set up by the U.S. Chamber of Commerce, from William Kovacs, an employee of the U.S. Chamber.

A few days ago I received a call from the administration informing me that, while they will not withdraw the notice for comments, it will in the next several weeks file another Federal Register notice providing for comment when all of the synthesis reports are public.

It seems to me that the APA rules and procedures are quite clear. Comments must be accepted, and generally they must be commented upon. Comments to the effect that not all the material backing the report was available are fair game, must be answered by the agency, and if true, might make a case for more careful scrutiny of any regulation coming from the report.

What did NOAA do? Nothing that we can see. Instead, what’s got Watts happy is a note from a hardball political group that they’ve heard from the White House, suggesting there will be political philandering with the science report.

Good scientists have significant science findings that would mitigate or contradict findings expressed in the draft report. Pointing those studies out to NOAA and the Climate Change Science Program would be the way to make a solid case.

The skeptics’ asking the White House to politically kill the report, and then celebrating a missive from a lobbying group that claims the report has been killed contrary to the law under the Administrative Procedures Act, doesn’t suggest that science is the concern of the skeptics — at least, that’s not the message I get.

In the wake of the news of one probably illegally suppressed report, it’s probably not wise to celebrate the suppression of another, legal or not.

______________________________

Update: As of Thursday afternoon (August 21), Watt’s Up With That? has changed the headline from “pulled” to “hold.”

The same criticisms apply from above, still.

August 20 is World Mosquito Day:

Pause for a moment on World Mosquito Day to reflect on the little bloodsucker that probably causes more human suffering than any other organism. Observed annually today, August 20, World Mosquito Day originated in 1897 by Dr. Ronald Ross of the Liverpool School of Tropical Medicine, according to the American Mosquito Control Association, a nonprofit based in New Jersey.

Ross is credited with the discovery of the transmission of malaria by the mosquito, and was honored with a Nobel Prize for Medicine in 1902.

Each year 350-500 million cases of malaria occur worldwide, and over one million people die, most of them young children in sub-Saharan Africa, according to the Centers for Disease Control and Prevention.

But malaria is not the only disease spread by mosquitoes. There’s also West Nile virus, various strains of encephalitis, Dengue Fever, Rift Valley Fever, Yellow Fever.

Beloit College Mindset list: No caller ID? No GPS?

August 19, 2008

Beloit College’s Mindset list is an annual event, now. The college puts together a list of things entering college freshman have never done without, trying to help faculty understand what freshman are thinking, and not thinking.

This year’s list, for the entering class of 2012, holds a few jolts for anyone over the age of 30. One last minute change was required, however, when Bret Favre left the Green Bay Packers for the New York Jets.

Here’s the list, and it continues below the fold:

Students entering college for the first time this fall were generally born in 1990.

  1. For these students, Sammy Davis Jr., Jim Henson, Ryan White, Stevie Ray Vaughan and Freddy Krueger have always been dead.
  2. Harry Potter could be a classmate, playing on their Quidditch team.
  3. Since they were in diapers, karaoke machines have been annoying people at parties.
  4. They have always been looking for Carmen Sandiego.
  5. GPS satellite navigation systems have always been available.
  6. Coke and Pepsi have always used recycled plastic bottles.
  7. Shampoo and conditioner have always been available in the same bottle.
  8. Gas stations have never fixed flats, but most serve cappuccino.
  9. Their parents may have dropped them in shock when they heard George Bush announce “tax revenue increases.”
  10. Electronic filing of tax returns has always been an option.
  11. Girls in head scarves have always been part of the school fashion scene.
  12. All have had a relative — or known about a friend’s relative — who died comfortably at home with Hospice.
  13. As a precursor to “whatever,” they have recognized that some people “just don’t get it.”
  14. Universal Studios has always offered an alternative to Mickey in Orlando.
  15. Grandma has always had wheels on her walker.
  16. Martha Stewart Living has always been setting the style.
  17. Haagen-Dazs ice cream has always come in quarts.
  18. Club Med resorts have always been places to take the whole family.
  19. WWW has never stood for World Wide Wrestling.
  20. Films have never been X rated, only NC-17.
  21. The Warsaw Pact is as hazy for them as the League of Nations was for their parents. Read the rest of this entry »

Alligator bait: Louisiana science teachers, and school boards

August 18, 2008

Louisiana’s state legislature — the legislature that the Supreme Court slapped down in 1987 for trying to introduce religion into science classes in Edwards v. Aguillardrushed through a bill drafted by the deaf-to-the-law Discovery Institute which purports on its face to make it legal for Louisiana science teachers to teach creationism, intelligent design, tarot card reading, UFO-ism, or any other crank science that the teacher feels compelled to offer.

A Louisiana alligator used by c design proponetsist Denyse OLeary to illustrate a blog post about Louisianas litigation bait law on creationism in schools.  Without any appreciation of irony, or as a subtle warning, we cant say.  (photo from The Advocate?)

A Louisiana alligator used by c design proponetsist Denyse O'Leary to illustrate a blog post about Louisiana's litigation bait law on creationism in schools. Without any appreciation of th irony, or as a subtle warning, we can't say. (photo from The Advocate?)

Louisiana’s Gov. Bobby Jindal, R-Mars, rushed to sign the brain-sucker into law, in his ambitious quest to get John McCain to name him as the nominee for vice president. It appears on the surface that Jindal’s national political aspirations will have to wait, but the law he signed requires Louisiana’s school districts to be ready when the students come back in the next few weeks, to do whatever it is they are going to do about creationism and other crank science.

Discovery Institute minions have been hawking creationism wares, and other creationists have offered to put Genesis into the science curriculum — but the law does not authorize those actions or wares itself. Instead, it passes the judgment to local school boards, sort of.

“Sort of.” Words that make a litigator’s heart flutter when talking about to-be-implemented laws! You’d think that, with all the money the Discovery Institute spends to entice legislators and school board members to poke their noses into matters they do not know, DI could spend a few thousands of dollars to get a competent legislative law drafter to draft a workable law. The cheapskates always pay more, Click and Clack say, and here’s another case to prove the point. It would have been difficult to intentionally write a law better intended to get local school boards sued.

A few of us noted the law does not indemnify local school districts against lawsuits if they goof and put religion into science classes. This is important, because the law requires local school districts to step up to the line and have a policy in place by the start of this school year. Which means, if the district doesn’t have the policy written out now, they’re late.

Tony Whitson at Curricublog spent time this summer pondering exactly how the law works, what it requires, and who it requires to act. His analysis — that the law is litigation bait just waiting to snare a local school board, a real “Dover Trap” — is cool, hard, and chilling. Go read it at his blog.

Whitson recommends that the Louisiana Board of Elementary and Secondary Education get an opinion from the state’s attorney general. This will not comply with the impossible and punishing deadline the legislature established, but it’s a much wiser stewardship of local monies, to try to avoid litigation. Tony wrote:

Taking stock of the situation: To summarize where things now stand, in light of everything above:

The law is by no means so benign as its promoters pretend. It will unleash all manner of chaotic mischief. On the other hand, there is a method to this madness, making it predictable that the perpetrators’ strategy will be to insinuate Exploring Evolution into the state’s (and then other states’) public schools.

BESE and the school districts cannot comply with the statute, which commands that

The State Board of Elementary and Secondary Education and each city, parish, or other local public school board shall adopt and promulgate the rules and regulations necessary to implement the provisions of this Section prior to the beginning of the 2008-2009 school year.

There are legal requirements (public notice, etc.) for adopting administrative rules for implementing legislation that make it impossible for that to be done by every state and district school board before the new school year begins.

So what can BESE do?

My suggestion is that BESE, at it’s meeting Tuesday, should move to request an opinion from the State Attorney General. They should ask him for an opion advising them, the district Boards of Education, and individual school principals, as to who will be responsible for the costs of defending against litigation for unconstitutional state promotion of religion in the use of supplemental materials. Presumably, if there’s a suit brought directly against BESE itself because of the substance of a text they have approved, then they would be defended by the AG’s office, on behalf of the state (like when the AG hired Wendell Bird as as special assistant for defending the state’s “Balanced Treatment” law). But will the AG commit his office to defending every district, every school, and every teacher whose use of “supplemental materials” is challenged for violation of the First Amendment?

Louisiana’s legislature set a trap for Louisiana science teachers and local school boards — whether intentionally or not is immaterial. Rather than authorize specific material for the curriculum, the new creationism law requires school boards to analyze materials to supplement the science curriculum. The law passes the buck to the local school boards.

So, Louisiana school board members now must become expert on science, and Constitutional law.

Rule of thumb: It costs a school board about $1 million every time they goof and put religion into science classrooms, in litigation costs alone. Louisiana’s legislature didn’t appropriate any money to compensate the school boards.

This law promises to entangle science educators and curriculum, and ensnare local school boards – all of which helps dumb down science achievement and prevent U.S. kids from getting the education they need to compete in a global economy. Alas.


Crankin the geology stupid past 11 . . .

August 17, 2008

It’s gotta be a virus, and pray to God it isn’t contagious.

Jennifer Marohasy made jaws drop with a stunningly under-informed claim about energy equilibrium and light bulbs, confusing watts as a measure of heat, getting thermodynamics wrong, and generally acting as if her wits temporarily headed to the beach.

And then she came right back with this one [moved to here]:

I have become curious about something. The core of the Earth is alleged to be molten. It’s also a fact that the deeper you dig into the Earth, the warmer it gets. Where is that heat coming from… surely not from the Sun. What’s the possibility that the Earth generates some of it’s own heat from geothermal processes?

The possibility is 100%. Ernest Rutherford had the goods on the issue just after the turn of the 19th to the 20th centuries. He won the Nobel Prize for Chemistry in 1908 for his work on radioactivity, which included calculations on how the planet Earth is heated from within. Some sources say Rutherford identified planetary heating as early as 1896.

Marohasy lives in Australia — is Google disabled for that continent or something?

These are the people who lead the charge for climate change skeptics? Anthony Watts, where are you?

This is a preview of the sort of ignorance that will elbow its way into Texas science if the State Board of Education succeeds in dumbing down Texas science classes, pulling down the intelligence quotient with creationism.

“Alleged to be molten.”

And water is alleged to be wet.


Creationist success: Thermodynamicophobia strikes climate change denialists

August 17, 2008

Every once in a while we get a glimpse of what the future would be like if the creationists ruled education and could teach some of the fantastic things they believe to be true as fact.

For example, creationists have for years complained that the basic chemistry of life somehow violates what chemists and physicists know as the “laws” of thermodynamics. Patient explanations of what we know about how photosynthesis works, and how animals use energy, and what the laws of thermodynamics actually are, all fall on deafened ears.

Comes Jennifer Marohasy, an Australian blogger at The Politics and Environment Blog, with this fantastic explanation about how the well-established notion of radiative equilibrium, simply doesn’t work.

“For the Earth to neither warm or cool, the incoming radiation must balance the outgoing.”

Not really.

No, really. Go read the post. And see these critiques, at Tugboat Potemkin, where problems with the rules of the principle of Conservation of Energy are noted, and Deltoid, where LOLCats makes a debut in explaining physics to the warming denialists.

Then go back and read the comments at Marohasy’s blog.

It’s not just the confusion of terms, like treating watts as units of heat. There’s an astonishing lack of regard for cause and effect in history, too:

Conservation of energy: it’s not just a phrase. The theory of radiative equilibrium arose early in the 19th century, before the laws of thermodynamics were understood.

Probably didn’t mention it here before, but Marohasy is also one of those bloggers who suffers from DDT poisoning. Among other things, she and Aynsley Kellow (whose book she recommends) use an astounding confabulation of history to claim DDT wasn’t harming birds at all, completely ignoring more than 1,000 research studies to the contrary (and not one in support of their claim).

Suggestion for research: Is the denialism virus that affects creationists, DDT advocates, and climate denialists, the same one, or are there slight variations? A virus seems the most charitable explanation, unless one wishes to blame prions.

Creationist physics, denialism in meteorology, physics, chemistry, and history. It makes a trifecta winner look like he’s not trying.

Spectacular waterfall discovered in Peru – adventurers off to document it

August 16, 2008

Gocta was unknown until a few years ago — to the outside world. Local Peruvians knew about it, but said little. Gocta turned out to be the third highest waterfall in the world

Lightning has struck Peru again: A week ago an expedition left paved-road civilization to document another very high waterfall, perhaps higher than Gocta, whose existence was only recently discovered, outside of local residents — who said nothing because they feared the reaction of the outside world, or they just didn’t think that anyone else would be particularly interested. The expedition includes “representatives of the sub-regional direction of Bagua Grande and Utcubamba, from Utcubamba’s National Institute of Culture, a topographer of the provincial municipality and a cameraman.”

Peru's Gocta, the third-highest waterfall in the world - Alberto Pintado photo

A local explorer, Obed Cabanillas Silva, who seems to be coordinating local efforts to make the cataract known, said there are “stone structures” on the path to the waterfall. Could there be undiscovered, uncharted ruins of former How does the rest of the world miss a waterfall higher than a 250-story building? Here’s a Google Earth challenge — how many other giant waterfalls are there in Peru, “undiscovered” by the rest of the world? Remember the recent discovery of an impact crater in Australia?

The expedition of “discovery” set off a week ago — can you beat them to the thing, on Google Earth, or with any other LandSat image? (The few pieces of data on the specific location I have are at the bottom of this post.)

Gocta itself came to light in 2005 when a German engineer working on a water project close by, persuaded the Peruvian government to survey the uncharted, unnamed waterfall. When the surveyors came back with a report the thing was 2,532 feet hight, the German, Stefan Ziemandorff, checked his National Geographic Guide, figured it was third largest in the world, and had the good sense to call a press conference to let everyone else know. (Ziemandorff first heard of the cataract in 2002.)

World Waterfall Database is more picky. They rank Gocta at #16 right now — something about free fall, flow amounts, other measures.

The discovery of Gocta produced documentation of other spectacular water features nearby, Catarata Yumbilla (870 m) and Cataratas la Chinata (580 m). One might wonder about what methodical search of the area might find.

Highest powered LASER in the world – in Texas, naturally

August 15, 2008

Longhorns must be proud. This is really cool science.

The University of Texas is hosting an open house for the Petawatt Laser. The Petawatt Laser is the most powerful laser in the world, creating “power output of more than 2,000 times the output of all power plants in the United States. (A petawatt is one quadrillion watts.)” The open house is August 28. (No, I didn’t get an invitation; Meg Gardiner’s husband got one.)

The laser is brighter than sunlight on the surface of the sun, but it only lasts for an instant, a 10th of a trillionth of a second (0.0000000000001 second).

Not me teach - I didnt shine that laser on your whiteboard.  (Seriously - Dr. Todd Whitmire, University of Texas, operator of the Petawatt Laser)

'Not me teach - I didn't shine that laser on your whiteboard.' (Seriously - Dr. Todd Ditmire, University of Texas, operator of the Petawatt Laser)

The laser reached greater than one petawatt of output in a test run March 31, 2008, at the University of Texas’s Texas Center for High Intensity Laser Science. The instrument will be used to create and study in extreme conditions, “including gases at temperatures greater than those in the sun and solids at pressures of many billions of atmospheres.”

This will allow them to explore many astronomical phenomena in miniature. They will create mini-supernovas, tabletop stars and very high-density plasmas that mimic exotic stellar objects known as brown dwarfs.

“We can learn about these large astronomical objects from tiny reactions in the lab because of the similarity of the mathematical equations that describe the events,” said Ditmire, director of the center.

Such a powerful laser will also allow them to study advanced ideas for creating energy by controlled fusion.

The Texas Petawatt was built with funding provided by the National Nuclear Security Administration, an agency within the U. S. Department of Energy.

Millard Fillmore’s Bathtub could use a petawatt laser, to keep the water in the tub warm, don’t you think?

An account of bioaccumulation of pesticides — dangers of DDT explained

August 14, 2008

Even short-time readers know of the problems of DDT advocates, denialists who seen to think we can poison our way to health — or worse, that we can poison others, in Africa, to health.

Here’s a voice from the other side, an Australian anti-pesticide, go-back-to-nature site, that tells a dramatic story from California:  The Permaculture Institute, “Pesticides, and You.” Clear Lake offered a dramatic example of the dangers of bioaccumulating chemicals, especially pesticides like DDT.

Without endorsing everything this group urges, I will say the clear, simple explanation of the events at Clear Lake is accurate, worth reading, and worth remembering.  It’s what Rachel Carson sounded the alarm to warn us about, and but for the movement spurred partly by her book, Silent Spring, it’s what we would have faced at countless other locations.

Institute for Creation Research: Still fraudulent after all these years

August 13, 2008

Sometime in the spring I let a long-running discussion with pastor Joe Leavell taper off. I thought I’d be back to it more quickly. It’s that sort of summer.

In one of his last posts, Joe said he’d been to a lecture by some folks from the Institute for Creation Research, the same bunch that tried to hornswoggle Texas into letting them grant graduate degrees in science education and biology for teaching creationism to their students instead, as a way of injecting creationism into the schools stealthily but still illegally. Texas refused to give them the authorityICR promises to appeal and sue for the privilege.

Joe said:

The response was rather lengthy, but they talked about the research that they have been doing over the past 7-8 years or so and the difference accredited scientists that are working for them. They also claimed that creationists get criticized for not writing peer reviewed articles in journals, but they claimed that they had submitted countless articles over the years and they all get rejected. They simply can’t get printed, was the claim, so they print their own stuff. They also pointed me to the RATE project, which honestly, without knowing a ton about science (though I do know some), is very convincing to me.

Here’s the link:
https://www.icr.org/rate/

The main argument that I found convincing was the presence of helium in the rocks which wouldn’t be there if the rocks were millions of years old. They said they’ve been working on this project about 8 years and have spent $1.5 million on it. They also submitted all of their research to top labs in the country to make sure they weren’t accused of “fudging” the evidence. Check it out (if you have time) and let me know what you come up with.

I’ll be brief in my response here, at least to start: Same old fraud, not even new wineskins.

Dr. Russell Humphreys, a famous creationism crank (to serious geologists and other scientists), claims that the amount of helium he detected in some zircon crystals was so high that the crystals could not be more than a few thousands of years old, rather than the millions of years old all other dating methods by all other scientists produce. Humphreys’ findings have never been submitted to any science journal for publication, but were instead distributed to donors to a creationist ministry.

Oh, Joe: These guys depend on a lack of normal skepticism and a lack of knowledge to perpetrate these frauds on honest Christians. I do wish more Christians would hold their feet to the fire.

A few observations:

First, this project exhibits most of Bob Parks’ seven warning signs of bogus science. Those signs are:

  1. The discoverer pitches the claim directly to the media. In this case, to media and donors.
  2. The discoverer says that a powerful establishment is trying to suppress his or her work. This thread runs through all ICR work. Humphreys’ later attempts at character assassination against his critics specifically for their critiques of the RATE project are exactly the warning sign of bogus science that we should expect, from bogus science. (See the final three paragraphs here.)
  3. The scientific effect involved is always at the very limit of detection. This sign, not so much.
  4. Evidence for a discovery is anecdotal. In place of the usual description of methodologies used so other scientists can replicate the measurement, we get a story about samples for other purposes, purloined for this measurement. Most of the critical references to the conclusion were unpublished, or revealed only in crank science publications.
  5. The discoverer says a belief is credible because it has endured for centuries. See the paper: “Many creationists believed . . .”
  6. The discoverer has worked in isolation. In this case, it’s difficult to know for certain; there is no methodology, no statement of where the work was carried, by whom, and no peer review. No other labs appear to be working on these issues. Dollars to doughnuts this work at government laboratories in Oak Ridge and Los Alamos is not catalogued in the labs’ work records, nor is it reported to Congress. Not only working in isolation, but completely on the sly.
  7. The discoverer must propose new laws of nature to explain an observation. Humphreys had earlier proposed diffusion rates far in excess of anything measured, and in this case, he assumes similar, completely uncorroborated conclusions.

Second, the conclusions have been challenged (“debunked” might be a better description) by scientists who know the subject matter. There’s a thorough discussion on Talk.Origins, by Kevin Henke (at the University of Kentucky); to summarize, there is no reason to think that helium could get out of those zircon crystals at depth, especially under the pressures at the depths the samples were recovered from; plus there are other problems:

Throughout Humphreys (2005), Dr. Humphreys stresses that his YEC conclusions must be correct because his Figure 2 shows a supposedly strong correlation between his “creation model” and vacuum helium diffusion measurements from Humphreys (2003a, 2004). However, Dr. Humphreys’ diagram has little scientific merit. First of all, his helium diffusion experiments were performed under a vacuum rather than at realistic pressures that model the subsurface conditions at Fenton Hill (about 200 to 1,200 bars; Winkler, 1979, p. 5). McDougall and Harrison (1999), Dalrymple and Lanphere (1969) and many other researchers have already shown that the diffusion of noble gases in silicate minerals may decrease by at least 3-6 orders of magnitude at a given temperature if the studies are performed under pressure rather than in a vacuum. Secondly, because substantial extraneous helium currently exists in the subsurface of the Valles Caldera, which is only a few kilometers away from the Fenton Hill site, Dr. Humphreys needs to analyze his zircons for 3He, and quartz and other low-uranium minerals in the Fenton Hill cores for extraneous 4He. Thirdly, chemical data in Gentry et al. (1982b) and Zartman (1979) indicate that Humphreys et al. and Gentry et al. (1982a) may have significantly underestimated the amount of uranium in the Fenton Hill zircons, which could reduce many of their Q/Q0 values by at least an order of magnitude and substantially increase Humphreys et al.‘s “creation dates.” Dr. Humphreys needs to perform spot analyses for 3He, 4He, lead, and uranium on numerous zircons from all of his and R. Gentry’s samples so that realistic Q/Q0 values may be obtained.

The “dating” equations in Humphreys et al. (2003a) are based on many false assumptions (isotropic diffusion, constant temperatures over time, etc.) and the vast majority of Humphreys et al.‘s critical a, b, and Q/Q0 values that are used in these “dating” equations are either missing, poorly defined, improperly measured or inaccurate. Using the best available chemical data on the Fenton Hill zircons from Gentry et al. (1982b) and Zartman (1979), the equations in Humphreys et al. (2003a) provide ridiculous “dates” that range from hundreds to millions of “years” old (average: 60,000 ± 400,000 “years” old [one significant digit and two standard deviations] and not 6,000 ± 2,000 years as claim by Humphreys et al., 2004). Contrary to Humphreys (2005), his mistakes are not petty or peripheral, but completely discredit the reliability of his work.

I think ICR is affect loaded. For years they argued that because there is so little helium in the atmosphere, the Earth cannot be very old. Helium gas floats to the top of the atmosphere and drifts off into space, so there can never be a large accumulation of the stuff in the air. ICR is making a similar argument here: That helium must migrate out of rocks and drift away. Alas, there isn’t much support for the claim that helium cannot be contained in a rock matrix, especially under significantly greater pressures achieved in large rock masses, deep underground. There are a lot of examples of gases being trapped in rocks; that helium in the air drifts away does not mean helium in rock will drift away.

Third, the RATE project tends to rely on disproven or highly questionable claims, rather than solid science. The claims of polonium haloes once were published in a reputable journal, but retracted by the journal after scientists trying to replicate the results discovered that the author had sampled much newer magma intrusions in granite*, and not the base granite at all (* that is, lava that squeezed into cracks in the granite). ICR continues on as if the paper had not been found faulty, as if the results had never been retracted. In any other context, this would be considered academic fraud at best. Were it done as research under a federal grant, it would be a felony.

Fourth, there is the issue of whether RATE can do anything other than fog up the area. One of the original goals of RATE was to date the rocks from Noah’s flood. As you know, claims that such a flood ever occurred are regarded as crank science among geologists. After several years of discussion and meetings, RATE participants announced they had been unable to distinguish which rocks on Earth are pre-flood, and which are post flood. Consequently, dating the rocks of the flood was precluded because they could not be found, reliably (or at all!).

This is long-term scam stuff, Joe. How many little old ladies and upstanding men in how many congregations have given how many millions of dollars to this quackery? Imagine what good could have been done had those dollars gone to honest enterprise among Christians.

Joe, does this stuff make you angry? It should. ICR confesses to have spent $1.5 million in this project over eight years — ostensibly a science project, and yet not one single publishable science paper out of it.

This is academic fraud of the most foul kind, to me. It angers me that ICR carries on these frauds with money contributed by trusting Christians. One has a right to expect better ethics from people who claim to be engaged in ministry for Jesus, I believe.
