Science can make you a better dancer - or at least improve your chances of not looking stupid to the opposite sex, say a group of evolutionary psychologists who used 3D motion-capture technology to create uniform avatar figures and identified the key movement areas of the male dancer’s body that influence female perceptions of whether their dance skills are “good” or “bad”.
Apparently it all comes down to neck, trunk, left shoulder and wrist, the variability of movement size of the neck, trunk and left wrist, and the speed of movement of the right knee.
Sounds simple, right? Read on.
We want to know some things in science are absolute yet we accept that a lot is relative. The speed of light is absolute and so the same with respect to any observer in empty space but sound is relative, like when a train whistle goes from high to low as it passes the observer. A longstanding quest in physics has been to determine whether chaos, in which tiny events lead to very large changes in the time evolution of a system, such as the universe, is absolute or relative in systems governed by general relativity, where the time itself is relative.
Like right after the Big Bang.
No, it is not a typo. I do mean "quirks": these are hidden-valley brothers of quarks predicted to exist in some fancy new physics scenarios. These particles have been sought by the DZERO experiment in a large dataset of proton-antiproton collisions, making use of a neat technique which I thought could be interesting to briefly explain today.
I like rocket photos and was getting a little jealous looking at all the Copenhagen folk's
photos. Where were
my rocket's photos? I'm launching the Project Calliope
music satellite with
Interorbital Systems (IOS) and even I don't know what my rocket looks like!
With all the fuss surrounding whether the l'Aquila earthquake should have been predicted, the point is often missed that it didn't need to be. As the recent Christchurch earthquake has shown, a city can survive relatively unscathed without an accurate prediction. All it takes is proper preparation.
