Falsifiability is useful, but a matter of judgment

Our discussions last week on Jim Baggott's book, 'Farewell to Reality', and Sean Carroll's Edge response, left me pondering falsifiability, the idea that theories should be falsifiable in order to be considered science. Falsifiability is a criteria identified by the philosopher Karl Popper.  Popper was arguing against a conception held at the time by logical … Continue reading Falsifiability is useful, but a matter of judgment

Ask Ethan #20: Is the Mars One crew doomed? – Starts With A Bang

What Mars One is counting on is that they can safely land a heavier payload than ever before, that they can do it more precisely than ever before (as in, within just a few hundred meters of previous successful landings), and they can do it for only 12% of the projected costs, with a total … Continue reading Ask Ethan #20: Is the Mars One crew doomed? – Starts With A Bang

Unapologetics: Time to ditch falsifiability?

SelfAwarePatterns made me aware of this essay by theoretical physicist Sean Carroll who expressed opinion that some scientific theories can still be called scientific, even though they are claimed to be unfalsifiable:

Modern physics stretches into realms far removed from everyday experience, and sometimes the connection to experiment becomes tenuous at best. String theory and other approaches to quantum gravity involve phenomena that are likely to manifest themselves only at energies enormously higher than anything we have access to here on Earth. The cosmological multiverse and the many-worlds interpretation of quantum mechanics posit other realms that are impossible for us to access directly. Some scientists, leaning on Popper, have suggested that these theories are non-scientific because they are not falsifiable.

The truth is the opposite. Whether or not we can observe them directly, the entities involved in these theories are either real or they are not. Refusing to contemplate…

The End of the World: Science or Religion? | Seth Shostak

Harold Camping died last month. In case you don't remember, Camping, the president of evangelical Family Radio, predicted that the world would end in 2011. Twice. He made these prognostications on the basis of numerology, which sounds like it might be a sophomore-level math subject, but isn't. The data for the calculations Camping used to … Continue reading The End of the World: Science or Religion? | Seth Shostak
