Finding a definitive answer to this question could certainly make someone very rich (butwhether that would in turn make them happy is another matter). The problem is that happiness is especially slippery. While we know much about the consequences of happiness – that it can improve our health and well-being and how we get on in the world – much less in known about its causes, let alone how to guarantee its appearance.

The large-scale studies, most of which are made possible by the vast data generated and collected by new technologies like sensors and cellphones, are very good at describing the big picture, but don't provide much detail at the individual level. Smaller-scale studies have the opposite characteristic: Their findings generally can't be scaled up from the individual to be applied broadly to populations.

In her paper published in the American Journal of Physical Anthropology, Kramer outlines how she compared the natural walking speeds of modern humans to those of two members of the Australopithecus afarensis species and found that such large differences existed between two members of our early ancestors that walking together would have been troublesome.

Now, it appears a 16 year old immigrant to Germany has done just that, and to top off his work, he’s also apparently come up with an equation that describes the motion of an object when it strikes an immobile surface such as a wall, and bounces back.

Instead, they alternately point the sound beam to either side of the target. The new findings by researchers from Maryland and the Weizmann Institute of Science in Israel suggest that this strategy optimizes the bats' ability to pinpoint the location of a target, but also makes it harder for them to detect a target in the first place.
