Wyatt Earp goes dancing

An evening pause: Here is an iconic movie scene from an iconic director (John Ford). The film is My Darling Clementine (1946), one of the best westerns ever made. Tough guy sheriff Wyatt Earp, played by Henry Fonda, makes the toughest decision in his life. And it has nothing to do with firing a gun!

Boulder tracks on Mars

Here’s a nice picture from the HiRISE camera on Mars Reconnaissance Orbiter, released July 7, showing the boulder tracks left by rocks bouncing down the escarpment of Kasei Valles in the low gravity of Mars. Fun quote:

Some of these blocks traveled downhill several hundred meters (yards) as they rolled and bounced, leaving behind a trail of indentations or poke marks in the surface’s fine-grained, light-toned soils. The raised borders in some of these poke marks indicate they are relatively recent features, unaffected by wind erosion, or that this soil has cohesive properties, such as if it was cemented.

The state of the polar ice caps, June 2010

On July 6, the National Snow and Ice Data Center (NSIDC) of the University of Colorado published its monthly report on the state of the polar ice caps. The Arctic ice cap, which this winter had been larger and more extensive than seen for many years, also shrank this spring at the fastest rate in years. (This chart, produced by data from the Japanese AMSR instruments on two research satellites, shows these trends very clearly.) Meanwhile, NSIDC reports that the ice cap in Antarctica is far larger than normal. Not unexpectedly, NSIDC immediately argues (quite unconvincingly if you ask me) that more ice in Antarctica is evidence for global warming.

From my perspective, the data continues to be inconclusive. We still do not really understand the long term trends of the Earth’s climate.

Jeff Foust analysis of the New Space business

Jeff Foust of the Space Review has written an excellent analysis today explaining why some new space companies have succeeded (SpaceX) and some have failed (Rocketplane). Key quote:

If your business plan requires hundreds of millions of dollars of investment, and your founders don’t have that money available themselves, it may be wise to reconsider that plan in favor of an effort that can bootstrap itself with much less funding.

Julie and Dick at Covent Garden

An evening pause: In a previous post, I described how I have always felt that Julie Andrews’ incredible screen presence was only rarely taken full advantage of during her career. In Mary Poppins — one the films that did showcase her wonderfully, Andrews’ co-star was Dick van Dyke, an amazing talent in his own right. For that film, Andrews and van Dyke had a chemistry that was riveting. In an earlier movie era, the studios would have taken advantage of that chemistry and cast them together again and again, much as Spencer Tracy and Katherine Hepburn were repeatedly cast together throughout the 1940s and 1950s. Unfortunately, by the 1960s the studio system was dead and such casting was impossible, and Andrews and van Dyke have never again appeared on the big screen together.

However, in 1974 they did do a television variety show special together, Julie and Dick in Covent Garden. One particular skit from that show not only demonstrated vividly the chemistry between Andrews and van Dyke and how we had lost something precious by not having them appear together in many films, the skit’s story itself illustrated in a most ironic manner these lost opportunities of life. Enjoy.
