stars were made rather than tracking the orbits of comets and planets. I find this significant because Herschel sought information that was different than what other astronomers were studying at the time. What was the motivation that led to the discovery? William Herschel was frustrated with the small telescopes he was using. He couldn’t afford larger telescopes‚ so he built one himself. He was observing a Nebula when he discovered Uranus. What questions were asked? How can he see it? What if

Leap Motion Many of us are aware of the Leap Motion with is a small‚ $70 gesture control system that simply plugs into any computer and‚ apparently‚ just works. The most important thing is that‚ if you’re familiar with the touch modality the interface is entirely intuitive (Christopher‚ 2012). It’s touch‚ except it happens in the space in front of the screen‚ so we don’t have to cover our window into our tech with all those unsightly smudges.

marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial‚ or centripetal.
