This is really a wonderful info!! You have made me remember the history of how Carl Sagan managed to convince the NASA to reverse the Voyager and take a picture to the Earth... when the probe was in Saturn too!!
In first place, he encouraged to make this with these words:
"It had been well understood by the scientists and philosophers of classical antiquity that the Earth was a mere point in a vast, encompassing cosmos—but no one had ever seen it as such. Here was our first chance, and perhaps also our last for decades to come."
If we consider that the original picture was taken by the Voyager in 1990, more than two decades have actually passed away!! Now, we have the opportunity of thinking again about our actual place in the Universe:
"I"t has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. It underscores our responsibility to deal more kindly with one another, and to preserve and cherish the only home we've ever known.
I learned about this wonderful story from Google News this morning - the first story seemed to come from Space.Com via FoxNews (of all unlikely sources to break a technology story) at 9:15 am on July 19th.
@Max, From what I've heard, everyone who has gone into space and seen the Earth below them has undergone a life-changing experience (even bigger that when I first discovered the power of beer).
Maybe for most people. Yet, some people may be beyond hope. I can see the jokes on Saturn now: is that really earth-shine or is that just so-and-so's (--insert favorite boviator's name here--) ego glowing?
@Rick: There hasn't been enough time for the film to be back from being processed!
LOL Actually I was talking to my 18-year old son just the other day saying that when I was his age we used to take pictures using 35mm film (typically you would buy the film and load it into your own camera -- later we used disposable cameras).
You wouldn't know if the picture you had taken was good at the time -- that wa smuch later. You had to take the entire roll -- then go down to the drug store and leave your film with them. They couldn;r develop it there -- they sent it off to the main factory. It could take a week or more before you could pick up your prints.
Now with digital cameras (still and video -- standalone and in your smartphones) we are so used to taking and sharing images that we simply don;t think about it anymore.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
