How to kill the dinosaurs in ten minutes

Ten minutes difference, and Earth would still be Planet of the Dinosaurs

Ammonites Haeckel

We have suspected for some decades that the dinosaurs1 became extinct as the result of a massive meteorite, an asteroid, hitting the Earth. We have known where the impact site was since 1990, if not before. But it is only last year that we successfully drilled into the impact site, and only now, for the first time, do we really understand why the impact was so fatal. And if the meteorite had arrived ten minutes earlier, or ten minutes later, it would still no doubt have inflicted devastation, but the dinosaurs would still be here and you wouldn’t.

66.1 million years ago, dinosaurs covered the Earth. 66 million years ago, there were none. And not only the dinosaurs, but the pterosaurs in the skies, the long necked plesiosaurs and even the ammonites in the oceans, and 75% of all complex animal life. No terrestrial vertebrate heavier than around 25 kg seems to have survived. What happened? Read the rest of this entry

The “scientific method”, a needless stumbling block. With a note on falsification

Science does not have a separate special method for learning about the world, the “scientific method” as taught in schools is a damaging illusion, and the falsifiability criterion has itself been falsified

Below, R: How not to; “The Scientific Method”, as inflicted on Science Fair participants. Click to enlarge

Consider this, from a justly esteemed chemistry text:

Scientists are always on the lookout for patterns.… Once they have detected patterns, scientists develop hypotheses… After formulating a hypotheses, scientists design further experiments [emphasis in original]

Or this, from a very recent post to a popular website:

The scientific method in a nutshell:
1. Ask a question
2. Do background research
3. Construct a hypothesis
4. Test your hypothesis by doing experiments
5. Analyze your data and draw conclusions
6. Communicate your results [emphasis in original]

Then, if you find yourself nodding in agreement, consider this:

Since a scientific theory, by definition, must be testable by repeatable observations and must be capable of being falsified if indeed it were false, a scientific theory can only attempt to explain processes and events that are presently occurring repeatedly within our observations. Theories about history, although interesting and often fruitful, are not scientific theories, even though they may be related to other theories which do fulfill the criteria of a scientific theory.

If you are familiar with the creation-evolution “controversy”, you may well suspect that last example of being so much creationist waffle, intended to discredit the whole of present-day geology and evolutionary biology. And you would be right. This quotation is from Duane Gish, a major figure in the twentieth century revival of biblical literalist creationism, writing for the Institute of Creation Research.1

L: Mike Pence, ” [N]ow that we have recognised evolution as a theory… can we also consider teaching other theories of the origin of species?”

Such nonsense isn’t funny any more, if it ever was. The man who may very soon find himself President of the United States is an eloquent spokesman for creationism.

And yet Gish’s remarks seem to follow from the view of science put forward in the first two excerpts. What has gone wrong here? Practically everything. Read the rest of this entry
