David Nightingale: Gerard K. O'Neill (1927 - 1992)

Apr 24, 2016

This essay is about Gerard K. O'Neill.

There are many O'Neills that are better known -- for example Eugene O'Neill, author of "The Iceman Cometh", or the nine-times-married actress and model, Jennifer O'Neill, known especially for her role in the movie "Summer of '42".

David Nightingale: Boltzmann (1844-1906)

Mar 27, 2016

Ludwig Boltzmann was born in 1844. He tried to end his life at age 56, and in fact succeeded (if that's the right word) at 62.

David Nightingale: Our Non-Winter

Mar 6, 2016

This winter, 2015-16, has been a no-show for much of the Hudson Valley. At the time of writing, Feb 29, there's no white stuff anywhere in sight. My snow blower, serviced and ready since November, still stands forlorn and unused in the barn, and misguided daffodils have been perking 3 inches above autumn's leaves since the end of January.

David Nightingale: Gravity Waves

Feb 21, 2016

When flying, it's sometimes possible to look down the domes of ordinary observatories such as in Hawaii or Chile, or onto radio telescopes in Puerto Rico or Jodrell Bank, but now, looking down on Italy or Germany or Louisiana or Washington state, it is possible, if not flying too high, to see L-shaped labs which are observatories for gravity waves. The arms of those 'L's are typically ~2 miles long each, and they house the laser beams that travel inside them.

David Nightingale: John Burroughs (4/3/1837 - 3/29/1921)

Feb 7, 2016

My younger son suggested an essay on John Burroughs, but I told him that probably everyone in the N-E knew more about the famous naturalist than I ever did. Apart from seeing a plaque at the top of Slide Mountain and a long-ago visit to his cabin, Slabsides, I knew very little.

David Nightingale: Granny D

Jan 24, 2016

"Back home in New Hampshire," wrote Mrs Doris Haddock, "I began walking my 10 miles a day with a heavy backpack. I am already a little stooped over, but it was manageable ..." [Ref.1, p.13]

Thus "Granny D", a then 88 year old retired shoe factory worker, described the plans for her walk across America, to raise awareness for Clean Elections and Campaign Finance reform.

  I've been sad, as many have, since Robin Williams chose to leave us, in August 2014. We realized there'd be no more statements like:

In past essays I've spoken of Morse from Poughkeepsie, Henry from Albany, and now -- George Westinghouse from Schenectady -- although he moved later to Pittsburgh, near where (at Wilmerding, PA) there is today a Westinghouse Museum.

David Nightingale: JJ & GP Thomson

This essay is about Nobel prize winning fathers and sons in physics, of which there are quite a few, focussing here on JJ Thomson and his son GP Thomson.  JJ is famous for having discovered the electron, and 30 years later his son discovered that it was a wave. Today we can correctly describe all particles, be they electrons or Volkswagens, either way.

David Nightingale: Charles Dodgson (1832-1898)

Nov 29, 2015

Learn well your grammar, / And never stammer,
Write well and neatly, / And sing most sweetly.
.....
Drink tea, not coffee; / Never eat toffy.
Eat bread with butter. / Once more, don't stutter.

The mathematician Charles Dodgson, who indeed suffered from stammering, wrote those lines when he was 13, and they anticipate his later nonsense verse, such as:

'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,
And the mome raths outgrabe.
