Perihelion and Aphelion

The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Notice how the planet moves fastest at perihelion and slowest at aphelion. 

The time during the year that aphelion and perihelion (when we are closet to the sun) changes over a roughly 100,000 year cycle, known as the Milankovitch Cycle.  Our orbit around the sun is not a circle, it is an ellipse with an eccentricity of about 0.0167.  This orbit both changes shape and rotates around the sun much like a spirogram tracing out a flower-like shape.

It is summer in the northern hemisphere, a time when people often say things like, “We are closer to the sun than we are in winter.”  This is not really true.  Summer is a product of the angle at which Earth is tilted, right now Earth is tilted so that the northern regions lean toward the sun.  In terms of orbit we are actually at the furthest point Earth gets from the sun.

This has interesting implications in terms of the global climate.  This means that right now winters tend to be warm (the planet is closer to the sun) and summers cool (the planet further from the sun).  In the big picture this places us in the midst of a global cool cycle, the type of situation that tends to lead to ice ages, like the one we are emerging from.

Leap: Touchless Gesture in 3D Interaction Space

This device will change how we interact with computers. It's a fundamental breakthrough in motion-sensing and touch-free gesture-control at a very low cost.

The Leap is a small iPod sized USB peripheral that creates a 3D interaction space of 8 cubic feet to precisely interact with and control software on your laptop or desktop computer.

The Leap senses your individual hand and finger movements independently, as well as items like a pen. It’s 200x more sensitive than existing touch-free products.

Hands-on review and technical details:

This video gives a realistic sense of what it's like to interact with the device: Leap Motion

The retail price has been announced at only $69.99. It's available for pre-order. Developers can apply now for SDK access.
