Real dope on human evolution

July 24, 2008

Subtitle this one, “DBQs in prehistory, paleontology, and anthropology.”

Younger son James complained yesterday about . . . well, about stuff he wasn’t taught. His questions to me were about what was available in the history textbooks on the great advances in science in the 20th century.

Very little is available, really. What had set him off was his summer reading where he’s been introduced, for the first time, to particle physics of the past 30 years. History texts may mention Einstein’s letter to FDR which started the Manhattan project. An outstanding history and science student in a U.S. high school can pass through the experience without ever learning what Einstein’s equation, E=mc², actually means, or how it pertains to his letter to Roosevelt, or when and how Einstein came up with it, how Einstein’s papers changed physics, how Einstein’s ideas were tested, how Einstein’s pacifism and Jewish heritage drove him to the U.S., and so on. Great advances in particle physics, or even in practical applications like CAT scans and PET scans, have fallen out of the books and out of the curriculum. 21st century medicine, but 20th century science texts and 19th century history texts. It’s the David-Bartonization of American education.

The stuff wasn’t covered in his AP physics or AP chemistry classes (what’s up with that?!), nor were most of the great discoveries even mentioned in any of the AP history courses.

No wonder the head of the Texas State Board of Education knows so little about science. Cue the country/western version of the story, “Been dumb as a stump so long it looks like genius to me.”** Plus, this makes it clear why the versions of curricula the SBOE head favors must be resisted.

Texas standards and national standards in history ask that students be familiar with American inventions and innovation. In reality that translates to Eli Whitney and the cotton engine, because it’s a key factor in the rise of plantation economics in the South prior to the Civil War; maybe some mention of water-powered looms; Edison and the light bulb; Ford and the assembly line; and maybe a mention of radio or television, usually with regard to the effects on culture. I know a teacher who has a great unit for Texas history on barbed wire and the Colt .45. World history mentions James Watt and the steam engine.* The Wright brothers and the airplane get a couple of sentences. Humans going to the Moon gets a few sentences, but not as much as Sputnik, because, well because Sputnik scared the bejeebers out of some of the people who yelled loudest at Texas and Florida textbook meetings, I imagine.

I’m not going to fix all of that, not right now. It’s a subject that deserves more time in the cooker, I think.

But I’m also working on plans for this next year. Pre-history human migrations, geological development of the planet — and last night I discovered a group hitting the Bathtub for information about humans and evolution. Sheesh! Another place where the history and science texts short the glorious science, where a student is more likely to be struck by lightning waiting for the bus than to get decent coverage of human evolution in the classroom. (Hey. Do you know a teacher who covers human evolution well in any subject? Put it in comments, below — I want to congratulate her, or him. I also want to steal the lesson plans.)

Here’s a quick fix, using some seminal documents that are perfectly classroom usable: Go to the Nature magazine website, and specifically look for the section, “focus on human origins.” If your administrators aren’t fully versed on No Child Left Behind, you can claim these as “research-based” (they are purely research-based; the law asks that our pedagogical methods be research-based, though, not the content, and that’s impossible; most of what we do in the classroom is tradition-based unsupported by any significant research, and federal laws and state regulations generally require the opposite of what the research says . . . don’t get me started). But I digress.

Nature is one of the premier science journals, a peer-reviewed or juried journal that is the prime place for key research findings to be published (along with Science, the other science journal giant). Most of their material is hidden away on the internet, held in proprietary sites available to scientists whose research institutions spring for expensive subscriptions (no, these journals are generally NOT available through the databases most high schools and non-research colleges purchase). Much of the best research of the last century is unavailable to high school teachers or students. This is true of chemistry, physics, biology and geology. The textbooks tend to obfuscate and cover the stuff up — or in the case of particle physics, ignore the field.

Several years ago Nature pulled about a dozen of the seminal papers in human evolution studies out of their vaults, making them available for free. These papers include some of the real classics:

Frankly, I wouldn’t expect to see these in a real DBQ in anything except, perhaps, human geography — but I can dream, can’t I? You can certainly create outstanding DBQ exercises with exerpts from these and a few other sources. Or you can simply use these complete papers in your classes. Except for a select few debate students at the upper echelons of competitiveness, real research papers fall out of the curriculum, and it’s a shame.

There is drama in these papers. Some of them shake the Earth, but in coolly scientific words. Ironically, the papers are not written so technically that they are beyond the ken of most high school readers. These papers are real history, real science, and our students deserve to read them.

Nature deserves our thanks for making these papers available. I wish other seminal papers were available, from Nature, and from other science and history research journals. Students would benefit from reading real history about the fall of the Berlin Wall, or the development of public health to fight tuberculosis. Students could mightily use to read about physics, biology, meteorology, geology, and other sciences upon which we rely to save the human race.

With six different AP or advanced world history texts, we came up with eight different answers, including two different years given for Watt’s work.

Atomic bomb madness: A real blast

July 23, 2008

Truly the lazy days of summer — I missed the anniversary of the Trinity Project, the first atomic bomb ever exploded, at White Sands, New Mexico, early on the morning of July 16, 1945. That was 63 years ago.

The New Mexico blast demonstrated that atomic bombs work. President Harry S Truman got the word of the successful test while attending the Potsdam Conference with Winston Churchill of England and Joseph Stalin of the Soviet Union.

Truman hoped to avoid a land invasion of Japan, which experts said would leave at least a million dead U.S. soldiers and five million dead Japanese. Truman was a soldier in World War I, who saw the trenches close up. He hoped to avoid anything similar for soldiers, and civilians. From Potsdam, Truman, Churchill and Stalin issued the Potsdam Declaration, ending with an ultimatum to Japan to surrender unconditionally or face terrible consequences.

Japan did not surrender. On August 6, 1945, the U.S. detonated the first atomic bomb used in warfare over Hiroshima, Japan, a city with large military support facilities. Within a few minutes, nearly 100,000 people were dead. When Japan failed to offer unconditional surrender even then, a second atomic device was detonated over Nagasaki, Japan, on August 9. (Had Japan not surrendered then a scramble would have been on — the U.S. had materials for about four more bombs, but they were not ready to go.)

1945 launched the world into the Atomic Age, by many accounts. The existence of atomic weaponry added to tensions on the planet played out during the Cold War. The creation of thermonuclear weapons, many times as powerful as a simple atomic bomb, only added to the tension. Perhaps we should call it the Atomic Angst Age.

Does that explain the fascination with photos of atomic blasts in recent days?

Wired’s online version noted the anniversary and included a slide show of atomic milestones, featuring a few blasts.

Then this post, from a blog named Picdit — “8 Insane Nuclear Explosions” rode the top of the popularity index of WordPress for the past couple of days. I’m not sure why these photos or the events they portray deserve to be called “insane.” I’m perplexed about why they are so popular.

These events around the creation, testing and use of nuclear arsenals resonate deeply with those of us who lived through any of these times. High school students have tested poorly on these issues during the past five years, however. Many of my history students do not know the significance of the classic mushroom cloud that marks an atomic blast.

I hope the curiosity is genuine curiosity for the historic events, that this curiosity leads to understanding of the destructive power of nuclear weapons, and that those tens of thousands who clicked on those images achieved an iota of understanding. I hope.

The First Bomb at Bikini, Charles Bittinger, 1946 - Captured at the peak of formation, this painting illustrates the classic mushroom cloud shape. The pink color of the cloud is due to the oxidation of nitrogen caused by high heat and radiation from the explosion. The rapidly cooling fireball is the cause of the red glow seen deep within the cloud. The blast wave created the massive waves and steam that engulfed the target fleet at the bottom.

Rachel Carson and DDT “ban” save millions of lives

August 27, 2007

Some are Boojums is back — that’s good news for truth seekers, science error debunkers and historians who care about accuracy.

Some are Boojums author Jim Easter guts the anti-Rachel Carson case in his relaunch post.

Pay particular attention to what Jim writes in conclusion:

That’s right. The 1972 DDT ban did nothing to restrict the chemical’s use against malaria, but had the effect of eliminating the single most intense source of selection pressure for insecticide resistance in mosquitoes. As the rest of the world followed suit in restricting agricultural use of DDT, the spread of resistance was slowed dramatically or stopped. By this single action, William Ruckelshaus — and, credit where it’s due, Rachel Carson — may well have saved millions of lives.

Steven Milloy is invited to add that to the DDT FAQ any time it’s convenient.

Particularly notable is Jim’s work to make available the much miscited administrative law ruling by Judge Edmund M. Sweeney. It is now available on-line, so the critics can now provide accurate citations to the decision, if their intent were to inform the public, instead of maligning the truth and misleading the public.

Mr. Easter’s applied history work in this effort is notable. The internet misses much of near-recent history, especially from the 1960s, 1970s and 1980s. Much of today’s political discussion could benefit from information that would be available in libraries, had libraries not suffered from great budget and priorities cuts in the last 20 years. Jim Easter’s contribution to making a more complete record of the history of DDT and the history of the EPA deserves applause.
