Science Break : The U-Curve

…This curve (Figure 1) describes the level of general happiness over an average person’s life.

Astute…

Science Break : Sociopathy

Science Break : Aerial Archaeology

…GIS technology, especially Google Maps and Google Earth, has given anyone the ability to view even the remotest parts of the globe. When my grandparents were young, in the late 1800’s, there were huge areas of the Earth that were simply blank spaces on western maps. The source of the…

Science Break : Prions

…Even before I saw the scratchy old movie clips of Papua New Guineans afflicted with kuru shaking spasmodically in the days leading up to their inevitable deaths, I found prions frightening. There is something otherworldly about prions, akin to a horrific sci-fi plague or biblical scourge, and they seem to…

Science Break : Baye’s Theorem in Practice

…As a follow up to his excellent September VIG column (Value of Integrated Geophysics, Sept. 2013 RECORDER) Lee Hunt suggested I build an article around Bayes’ theorem. Lee has published an article with some excellent examples of Bayesian methods before (Hunt, 2013), but we thought something fluffier would make for…

Science Break : Encryption part two – the digital era

Science Break : Did they or didn’t they?

…I love a love story as much as anyone, and the romance that has had me on tenterhooks for at least 15 years happened (or did it?) over 50,000 years ago. I’m talking about humans and Neanderthals – did they or didn’t they? Science has been tormenting, teasing, and tantalising…
