Now about the rocket science. To begin with, it turns out the Jet Propulsion Laboratory is no longer that concerned with jet propulsion other than hitching a ride with a rocket to get to where they need to go. Their main focus these days is on robotics. Their mission control center is all about sending and receiving signals through millions and even billions of miles of space. For example, the photograph that is on this page and featured in the video showing Earth as seen from Saturn, was taken by the Cassini orbiter. if you wanted to be in the photograph (not that anybody would really know you were) you needed to be facing Saturn and smiling and waving about one hour and 20 min. before Cassini actually snapped the shutter. That is how long it takes the light waves to get from Earth to Saturn.
But on a more down to earth example, the camera I used, my GoPro, is a marvel of technology in its own right. Slightly larger than a matchbox and not much heavier, it can shoot video that is 4000 pixels wide and I control it with my iPhone. Despite being unable to move my fingers, I was able to compose a fairly complex score to go with the video using Logic Pro software on my iMac and a Korg Nanokey keyboard that is perfect for me since the keys merely need to be touched. The video editing was done using Final Cut Pro X, an amazing software program that puts the equivalent of a million-dollar video production studio onto my desktop for a cost of about $300. Finally, I am dictating this entire blog, along with tens of thousands of words that I have recently written for books in progress using Dragon Dictate voice-recognition software.
Thank you scientists everywhere, and please keep these wonderful innovations coming!
