Just after sunset Venus and Jupiter are dancing together in the Western sky. Venus is the brighter of the two, in fact she's the brighter than anything but the Sun and Moon. Throughout the month of June, at least as seen from Earth, they've been getting closer and closer and... Continue reading

Motor vehicle deaths are currently running about 33,000 per year in the US. While there are many ways of looking at the numbers, perhaps the most remarkable is we find the carnage acceptable. It is possible to simply reduce the death rate without new technology, but car performance would become... Continue reading

A few days of heavy rain and 83° turned the noon walk through the woods into something of a steam bath making them feel like a tropical swamp. The soft ground and heavy winds during a thunderstorm last night felled a large white oak leaving a huge hole in the... Continue reading

Someone asked if I liked to watch horror/scifi movies. It depends... A few years ago I was trapped on a cross country flight and saw The Black Hole - one of those scripts that is so bad it is almost, but not quite, worth watching. Check out the trailer... Most... Continue reading

well? are you going to get one? Since I have an interest in ubiquitous sensors and computation many people assumed I'd get an Apple Watch the moment it came out. Something more interesting happened and I found myself with questions about what computation on the wrist is good for and... Continue reading

They appear as electric blue wisps well after sunset - far too long to be normal clouds, but there they are reflecting sunlight from about fifty miles above the Earth. I've only been lucky enough to see two noctilucent clouds in my life so far and I've been hunting since... Continue reading

A few days ago someone flashed his Apple WATCH announceing he might periodically take standing breaks at the watches' promptings. Apart from being a bit socially odd at this point the idea seems like it may be good. There is a a body of research showing that extended sedentary periods... Continue reading

What do you think of the new iPhone? A reasonable question, but I couldn't say much as I didn't have one yet. I was with a very eclectic group of people that got together a few times a year for conversation and a month had passed since the iPhone went... Continue reading

the grey unknown was acceptable for so long. but as we approach, color leaks in. Science has this wonderful feature. When you use an instrument that gives a difference view, you are often rewarded with with new beauty and puzzles. The Hubble Space Telescope was one of those dramatic leaps... Continue reading

I was about eight when we acquired our first five transistors. They were in a portable AM radio that didn't need to warm up and ran on a 9 volt battery. It was something of a revelation to me. Up until that time the only portable radio we had wasn't... Continue reading

The Internet of Things Doesn't Exist - The other day I gave a conjecture talk on some possible architectures and evolutions of networking and computation to support densely deployed sensors and actuators. There are times when you resort to catchy title to attract an audience. This was successful in filling... Continue reading

In high school you probably learned about the properties of infinite series. Things like the sum of the reciprocals of the powers of 2: 1/1 + 1/2 + 1/4 + 1/8 + 1/16 + ... converges on 2, but the sum of the reciprocals of the positive integers diverges: 1/1... Continue reading

In the past week at least a dozen people have asked if I will buy an WATCH. I tell them probably not - at least not this iteration. Watching reactions is interesting so I try to remain passive and let them take the direction of any discussion that follows. The... Continue reading

The perception of the world that our brain assembles from sensory information is limited in scope and, as a certain dress demonstrated a week ago, not terribly accurate. That doesn't diminish the richness of what we do perceive. After all, we often find enormous beauty in black and white photography... Continue reading

There is a considerable amount of confusion involved in the reporting of today's FCC network neutrality decision. Rather than getting into it and my bias, I suspect it might be more useful to spend a bit of time talking about what the Internet is and isn’t.1 A few weeks ago... Continue reading

During a Christmas holiday in the late 70s I lugged our group's Texas Instruments Silent 700 back to Montana to for a bit of programming. The computers for our experiment were at Brookhaven National Laboratories and Stony Brook on Long Island. Huge multimillion dollar machines that ran programs in batch... Continue reading

Get behind the wheel of a car from 1950 and you probably can figure out how to drive it. Cars are now vastly more refined, the highway system is greatly improved and cities and suburbs have been shaped by the automobile. But the basic car, at least to the driver,... Continue reading

A billion? You're telling me a billion twenty five to forty years from now? A billion! you're pulling my leg, right? Rich smiled. I did the same and added 25, maybe 50 years. If I had to bet closer to 25 Two hours with the patent attorney. He didn't buy... Continue reading

With their wonderful noses, how does the world appear to a dog? Does a bat's echolocation augment their vision or does it create a separate model of their world? Does your perception of reality differ from mine? Brookhaven National Labs was a large enough reserve that it had its own... Continue reading

You may have seen this simple electric train A very simple class of electric motor that operates using one of the four fundamental forces of Nature - electromagnetism. Electricity was an area of active investigation in the early 19th century when one of the experimenters, a Dane named Hans Øersted,... Continue reading

This new fangled radio technology was beginning to get exciting. Spark gap transmitters had been used to wirelessly send signals to a receiver. In 1888 Hertz was able to show the transmitters were producing electromagnetic waves predicted by Maxwell a quarter of a century earlier - waves that travel through... Continue reading

5:25 am - excellent! I brush the last of the snow from my coat and switch on the lights before taking my seat. A few minutes of silence and then a door opens and closes reverberating for about three seconds. The clicking of shoes echoes through Warner Hall as she... Continue reading

I'm really enjoying Om's new project. His latest piece is an interview with Frank Clegg - a guy who found his life's passion designing and making high quality leather goods. You really must go over to the site and read it. As I get older I find myself more... Continue reading

Not long ago I was in a very dark area on a clear moonless night. Andromeda was well above the horizon. I hadn't seen it clearly in awhile and just thinking about it fires your imagination - its light took well over two million years to make it to Earth.... Continue reading
