Christopher Matthew, A Storm of Spears: Understanding the Greek Hoplite at War. The most important conclusion from this is how the Greeks wielded their spears. Despite all the pictures, they did not hold them over their heads with a back-handed grip. Instead, they held them with the butt of the spear tucked under their armpits. This allowed for much greater reach and strength. Lots of good experiments with re-enactors.
When hipsters are too slow in detecting the trends, they will keep making the same choices and therefore remain correlated as time goes by, while their trend evolves in time as a periodic function.
…two different research groups announced the discovery of the same new particle and redefined how physicists view the universe.
Brian Schmidt is the world’s only vintner with a Nobel Prize in physics, specializing in pinot noir because the climate and soil (or terroir) is especially well suited for that varietal. He and is wife own a four-star winery called Maipenrai (Thai for “It’s all right”) in Sutton, New South Wales, near Canberra.
The link between atmospheric CO2 and rising global temperatures cannot be dismissed as a case of “correlation and causality.” Continue reading
No profession is free from the kind of miserable jerks who ruin it for everyone else. No intelligence level is either. When great intelligence, prestige careers, and big egos come together, things get ugly. Johann Bernoulli was, as a person, very ugly.
Special relativity predicts that a twin in a high-speed rocket, as viewed by his Earth-bound brother, will have a slower-ticking clock. A precise test of this time dilation, first performed in 1938, involves observing the frequency shift—or “ticking” change—in the electronic transitions of fast-moving ions. An update of this type of experiment using lithium ions has now verified special relativity’s prediction with unprecedented accuracy—a result that provides additional constraints on quantum gravity models.
