Animations of Saturn’s aurorae

Earth isn’t the only planet in the solar system with spectacular light shows. Both Jupiter and Saturn have magnetic fields much stronger than Earth’s. Auroras also have been observed on the surfaces of Venus, Mars and even on moons (e.g. Io, Europa, and Ganymede). The auroras on Saturn are created when solar wind particles are channeled into the planet’s magnetic field toward its poles, where they interact with electrically charged gas (plasma) in the upper atmosphere and emit light. Aurora features on Saturn can also be caused by electromagnetic waves generated when its moons move through the plasma that fills the planet’s magnetosphere.  The main source is the small moon Enceladus, which ejects water vapor from the geysers on its south pole, a portion of which is ionized. The interaction between Saturn’s magnetosphere and the solar wind generates bright oval aurorae around the planet’s poles observed in visible, infrared and ultraviolet light. The aurorae of Saturn are highly variable. Their location and brightness strongly depends on the Solar wind pressure: the aurorae become brighter and move closer to the poles when the Solar wind pressure increases.

Scientists break down the physics and neuroscience behind Bruce Lee’s legendary one-inch punch, the bodily application of his famous "be like water" philosophy.

Drawing upon both physical and neuro power, Lee’s devastating one-inch punch involved substantially more than arm strength. It was achieved through the fluid teamwork of every body part. It was his feet. It was hips and arms. It was even his brain. In several milliseconds, a spark of kinetic energy ignited in Lee’s feet and surged through his core to his limbs before its eventual release.


Every bodily jerk has an apex of force. To not only maximize on that force — but to augment it — Lee perfectly synchronizes his movements, one after the other, linking them like boxcars on a train. To be sure, countless muscle men have been stronger than Lee, but few, if any, could deliver more more power than Lee with just one inch.

What makes the difference? Lee’s brain.

Or, one might argue, Lee’s mind.

The full article is well worth the read.

" Music rhythms are mathematical patterns. When you hear a song and your body starts moving with it, your body is doing math. The kids in their parents’ garage practicing to be a band may not realize it, but they’re also practicing math. "

Kissing her and letting her moan into your mouth is even sexier
