Janet Stemwedel at Adventures in Ethics and Science explains what’s involved in testing a theory:
Often (but not always), when scientists talk about testability, they have something like falsifiability in mind. But testing a theory against the world turns out to be more complicated than testing a single, isolated hypothesis.
Janet Stemwedel at Adventures in Ethics and Science explains the scientific concept of falsifiability.
what does it mean for a claim to be falsifiable, and why does falsifiability matter so much to scientists and philosophers of science?Actually, it’s not just falsifiable claims that the science crowd cares about, but also falsifiable theories. Let’s start with claims because they’re easier
The first full study must have just finished, because this is in the news again. Like the famous La Brea and other tar pits, a crevice in Australia trapped many animals, creating a picture of life then. These animals come from a time 800,000 to 200,000 years ago, a time that supplies few fossils. The specimens include the first complete skeletons of the marsupial lion, Thylacaleo carnifex, and eight new species of kangaroos.
The three caves in question were found in May, 2002, by aerial survey and initially explored in July of that year. They were found not by scientists but by cavers who were using ultralight planes to look for new caves to explore.
The animals are very well preserved, leading me to wonder if any DNA might be recovered.
Wow! You are awesome! You are a true Biblical scholar, not just a hearer but a personal reader! The books, the characters, the events, the verses – you know it all! You are fantastic!
This quiz was clearly biased towards high scores. Most of the multiple-choice questions had at least two answers that could be eliminated right away because they were silly.
