Not as dumb as (you think) they look

November 21, 2009

A common argument against past human achievements – that they are either fraudulent, or the result of superhuman intervention – is the supposed impossibility of those achievements. The Nazca lines, the pyramids, astronmical discoveries, Stonehenge etc.  A whole field of woo, starting with von Däniken’s Chariots of the Gods? is based on the premise that past humans could not have been clever enough to do things, simply because we, today, don’t know exactly how they did it.

The argument devolves to “I can’t figure it out, so how could they figure it out?” or, more simply “Nobody in the past could possibly be smarter than me.”

That’s why I love this TED video. It shows a simple device invented millenia ago, but I would wager far fewer than 1% of people alive today – especially in the developed world – could figure out how to make one.


Another blow to “Irreducible Complexity”

November 4, 2009

As reported in Science Daily, Dr. Joe Thornton at the University of Oregon has reconstructed an evolutionary sequence of an “irreducibly complex” system – alosterone and its receptor.

“Our work demonstrates a fundamental error in the current challenges to Darwinism,” said Thornton. “New techniques allowed us to see how ancient genes and their functions evolved hundreds of millions of years ago. We found that complexity evolved piecemeal through a process of Molecular Exploitation — old genes, constrained by selection for entirely different functions, have been recruited by evolution to participate in new interactions and new functions.”


Quote of the Day

October 29, 2009

As a dancer and choreographer I’ve spent a tremendous amount of my life defending something that’s very hard to see. I mean, people see dance, they see the dancers, but they have trouble understanding why it’s valuable, what you are trying to say.  And in some ways I feel that’s reflected in what I learned initially from the physicists. It’s very abstract, it’s hard to see, people have trouble trying to understand it. It has tremendous value to us as a civilization but it’s not easy to explain.

Stupid Quote of the Decade

May 22, 2009

Don McLeroy, chair of the Board of Education in Texas has this to say about Science:

Somebody has to stand up to the experts!

He even goes on to describe these experts as

…very brilliant, wonderful people

who certainly know a shitload more about evolution than McLeroy too, but somebody has to stand up to ‘em. Just ’cause.

On Hitler, Darwin, and Social Newtonism

May 14, 2009

In the movie Expelled, as well as a number of other sources, it is repeated over and over that Hitler’s eugenic and antisemitic views were influenced by Darwin, and thus Darwin and his work on Natural Selection are inherently evil.

It takes very little research to discover that Hitler in fact used the Bible and tenets of Christianity to justify his actions, and any association with natural selection or evolution is in name only, and not in reality.

Allow me to illustrate with an example of a made up scheme of Social Newtonism: 

According to Newton’s law of gravitation, tall people have more potential energy than short people. Now, everyone knows that having potential is a good thing, and having energy is a good thing, so clearly any tall person – with greater potential energy – is superiorto any short person. As such, it could be suggested that only tall people should be allowed to reproduce, in order to ensure the future improvement of the human race. And because this is so clearly based on physical laws, I will call this Newtonics, or Social Newtonism.

Now, should the response to this be:

Since Social Newtonism is clearly misguided and evil, we will call Newton the Antichrist, and stop teaching Physics in school.

or:

So called “social Newtonism” has nothing to do with Newton’s laws other than hijacking his name, is a complete misrepresentation of physics, is merely an excuse to promote prejudice, and should be exposed as such. Newton’s laws should be taught more and better, to ensure this type of gross misrepresentation should never happen again.

Which is the correct response? Clearly not the first. So please tell me why it is that this is precisely what is happening with Darwin’s theory of Natural Selection? I understand the motivation (discredit Darwinism so fundamentalist Christianity can be rammed into the school system to indoctrinate children when they are young and susceptible), I mean why are people letting it happen?

To put it plain and simple, blaming Darwin for Hitler is a lie. Isn’t there something in the bible about not telling those?

A History of Public Education

May 7, 2009

This was forwarded to me, sorry I don’t know the origin, but there a number of variants out there.

A history of public education

Teaching Math In 1970
A logger sells a truck-load of timber for $1000.
His cost of production is 4/5 of the selling price.
What is his profit?

Teaching Math In 1980
A logger sells a truck-load of timber for $1000.
His cost of production is 4/5 of the selling price, or $800.
What is his profit?

Teaching Math In 1990
A logger sells a truck-load of timber for $1000.
His cost of production is $800.
Did he make a profit?

Teaching Math In 2000
A logger sells a truck-load of timber for $1000.
His cost of production is $800 and his profit is $200.
Your assignment: Underline the number 200.

Teaching Math In 2009
A logger cuts down a beautiful forest because he is totally selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands.
He does this so he can make a profit of $200. What do you think of this way of making a living?
Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes?
(There are no wrong answers. If you are upset about the plight of the animals in question, counselling will be available)
