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

Time for a little experiment. Take a piece of the best dark chocolate you have and snap off a section. Put it in your mouth but don't chew it - the trick is to experience it properly. At first you just notice its crisply defined shape and a tiny bit... Continue reading

There are days you remember. October 17th, 1989 and I was on the phone with a mathematician friend who had just walked out of a meeting with an image processing company in Silicon Valley. We had done a bit of work together and our lab was shopping it around the... Continue reading

happy holidays OK - here is the 20th year of the card I first put up around now in 1994 ... the last host went out of business and my free hosting doesn't support auto streaming, so you'll have to click on the player to listen.. The drawing came together... Continue reading

42 It was Jean's birthday last week. When I know someone's age I sometimes send a few examples of where the number comes up. There was the beautiful Orion nebula M42, a musical based on a street in New York, the atomic number of molybdenum, the critical angle that describes... Continue reading

I try to average about 150 watts for an 80 minute period on the rowing machine. I'm about 20% efficient, so I need to move about 600 watts out of my body. Humans are well designed for dumping heat and within a few minutes I'm sweating - really sweating. The... Continue reading

The Arizona desert is a fine place for getting reacquainted with some old friends in the night sky. The air was dry and almost chilly and moonless sky was as transparent as the dark Montana skies I knew as a kid. The mountains on the horizon cut their blackness into... Continue reading

A follow-on discussion with Jheri after the last post centered on words and concepts that are well-known within a culture, but are so much a part of the culture that they are difficult or impossible to define on the outside. The Danish concept of hyyge came up. Sometimes called coziness... Continue reading

Many words and phrases commonly used by scientists have very different meanings to non-scientists. Energy, power, mass, inertia, momentum, confidence, model, space, measurement, error, signal, color, space, time, vacuum, evolution, theory, particle/wave duality .. the list goes on and on. A certain amount of code switching is necessary for effective... Continue reading

Frank's single-wide was cozy with both the propane furnace and the wood burning stove blazing against the -20°F night. Warm cinnamon buns, hot chocolate and blankets made up for the trailer's thin insulation as we talked almost until dawn about the Internet and Montana's native people. Frank ran The Big...

After all these years my mother still holds the record for the most tragically wrong holiday gift. The sad thing is most of it was thought-out and given in the spirit of goodwill and love. Unfortunately a misunderstanding of psychology set the stage for some holiday bad cheer. The year... Continue reading

I was at my favorite Gelateria and asked one of the owners if she remembered someone. She looked at the photo on my phone and a big smile came to her face. Oh! The thin one with the golden hair and the gold spoon. She always orders a pint and... Continue reading

The other day I was using one of my slide rules while waiting for a train. I was absorbed in calculations until someone interrupted me wanting to know what I was doing. People tend to be mystified when they see an unfamiliar technology. Slide rules are simple in concept. When... Continue reading

It had been about two years since I had seen a friend’s daughter. She was about thirteen and much taller than the last time I had seen her. He made complaints about having to buy new clothes and her appetite, but such is growth in kids. Consulting a children’s growth... Continue reading

I skate to where the puck is going to be, not where it has been. Wayne Gretzky sold himself short. He had the experience to figure out where the puck was going, but sport at the highest level is much deeper. He managed to skate where the puck would be,... Continue reading

Last week news came from the Borexino collaboration that an accurate solar neutrino flux measurement had been made. A fantastically difficult observation that not only confirms the basic model of how solar fusion works, but also gives a window into the near real-time production of energy in the Sun. Although...

At the 1986 SIGGRAPH conference a short computer animation from a small company called Pixar wowed the audience. Technically it was a breakthrough, but more stunning was the audience's reaction. The technical crowd was not asking questions about the new animation techniques it highlighted, but wanted to know if the... Continue reading

On Friday afternoons a few of us would meet mostly to talk about ideas. A playground to frame and test ideas involving a small number of people who knew each other well. At one point there was discussion on changes in the government's support of corn based ethanol production. Sorting... Continue reading

Thomas Jefferson had the reputation of an extreme bibliophile, but was forced to make choices 'only' reading about 7,000 books. Ben Franklin had a similar information challenge and both men were unable to fully respond to their mail. They lived at a time when it seemed like a powerful and... Continue reading

As I paged through the old book, a paper slid out and fell to the floor... The book was a bound collection of magazine articles on the development of television and may have been from a personal library as there were several volumes from the late 1920s to the beginning... Continue reading

The American public is remarkably out of step with the findings of the science of global warming. Generally less than half of the public agrees with the statement there is solid evidence for global warming caused by human activity in contrast with the very strong consensus among scientists.1 Curiously public...
