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...

... and does it seem like it is getting hotter to you? While doing a bit of cleaning in the kitchen I found a surprise a friend had hidden nearly in plain sight. I was on the step stool storing some things that are rarely used high in the cabinets... Continue reading

The transportation system is enormously fascinating and complex. There were a few decades of radical developments in the automobile about a century ago coupled with the growth of energy, roadway, legal, safety and other systems. The growth in the adoption of the car caused an enormous expansion of a sprawl... Continue reading

The other day I was out walking around noon looking at the trees. Some took a lot of damage from the harsh Winter, but almost all have enough leaf area to catch most of the light striking their habit. The average maple around here this time of year is averaging... Continue reading

Stripped to the basics a vehicle is just a device that moves by converting stored energy into mechanical energy. In the early days of the automobile it wasn't clear what the stored energy would be and how it would be converted. Experimenters worked with steam engines, a wide variety of... Continue reading

Colleen and I spent a fair amount of time trying to understand how to talk about energy issues. 1,000 miles per gallon on a bicycle gets attention as does telling someone for every four gallons of gasoline they use only one moves the car and the other three are mostly... Continue reading

Bob and I would sometimes get in a family car and drive to the top of Gore Hill just to see if we could coast back down the hill to the river. It was a bit tricky with his dad's old Chevy working better than our family Falcon. The Chevy... Continue reading

When I was a teenager consumer grade microwave ovens were beginning to appear. They were very spendy - much more than a conventional oven - so there was a need to convince people there was a deep need. They seemed to settle on the microwave as a cook-almost-everything, but do... Continue reading

Imagine a solid that was a better insulator than almost any other solid and that, at the same time had a very low density - getting down to the density of air at sea level. I was paging through some papers in the latest issue of Nuclear Instruments and Methods... Continue reading

Imagine what it must have been like to look up at a moonless and clear night sky in preindustrial times. Perhaps a few thousand stars would fill the sky and perhaps you would wonder how far away they were. Figuring that out has taken a lot of time - the... Continue reading

Tonight I waited by our pond hoping to see a bat. Spring is finally here and there are more than enough flying insects to tempt a bat, but nothing. The past few years have been terrible for bat watching - I'm afraid white nose syndrome has taken its toll. Still,... Continue reading

Early August marks the State Fair in Great Falls, Montana. The latest farm implements, horse racing, a lame midway, deep fried everything, homemade lemonade, 4H and, of course, cow chip tossing. As a high school student I remember watching a rather large and enthusiastic teenager, perhaps inspired by the Summer... Continue reading

I'm finally up to date with the first four episodes of Cosmos - enough that I have a sense of the show's approach. The fact that Seth MacFarlane, Neil deGrasse Tyson, Ann Druyan and others were able to pull this together and to have it aired on network television is... Continue reading

I've seen two episodes of the new version of Cosmos so far. I was going to wait a bit longer before commenting, but something came up. It is remarkable to see a show on current science on an American TV network during prime time. Finding the right level for something... Continue reading

Such a remarkable day with the announcement of the detection of primordial gravity waves from the earliest moments of the Universe. The nature of the detection may open up a lot of unexpected experimental physics. The tensor fluctuations write quantum gravity on the sky - Liam McAllister earlier today I'll... Continue reading

Friday was pi day. I don't know when people started celebrating the fact that the American notion for March 14th looks something like the first three digits of the irrational number pi, but it has grown into something of an event in schools. Along with being a good excuse for... Continue reading

Many years ago I lived in Southern California. While the weather was foreign to my Montana experience, what really impressed me was the pollution - thick, stinking photochemical smog and soot. At least once a week you had to clean a brownish film from the windows and wondered what your... Continue reading

what is a ruby and why is it red? why is the friction so low on a sled? on a plot of P versus T, sketch out the phases of helium three. Janos loved simply stated questions - and took delight if he could make them rhyme. I had thirty... Continue reading

Our Winter has been impressive. The ice on the local pond is nearly strong enough to support a person. Yesterday an epic storm gave an excuse to enjoy the season. I ended up getting very wet and cold, but for whatever reason you learn to love the Winter if you... Continue reading

I tend to worry about labels and definitions as it is extremely difficult to achieve depth in anything where you aren't clear on the basics. A term that has bothered me for some time is digital native. It is generally invoked to imply the generation that grew up with an... Continue reading

During the last Winter Olympiad, almost exactly four years ago, a friend was rewarded with a special bicycle. Thinking about this and watching Sage Kotsenburg take the gold in Slopestyle triggered a few thoughts. Colleen is one of those people who goes out and just does it. She was worried...

We finally had a break in the weather and I was able to spend a lot of time in the woods yesterday. The Sun angle was noticeably higher and the snowy landscape was criss-crossed the the tracks of at least a dozen different kinds of animals. The bonus that made... Continue reading

The past half year has been a period of loss in my life. These periods happen, of course, but it has been particularly concentrated and has forced a lot of thinking. During one point last December a close friend called to see how I was doing and after listening for... Continue reading

Indulging in some fine ice cream I found myself thinking about my Grandpa Joe. Good ice cream was an art-form to him and he exposed me to good homemade examples early on. These days I rarely have it and usually make my own, but every now and again a very... Continue reading
