Anyone who's jumped off a haystack or played on a trampoline, knows the pleasurable feeling of weightlessness, wherein there are, for a fleeting moment, no more sagging body parts.
Felix Baumgartner, a 43-year old Austrian military parachutist, intentionally jumped from a capsule 24 miles up, on Oct 14, thus certainly knowing weightlessness for a decent amount of time. And what a fascinating lot of physics the man who fell from space experienced!
Well, I guess this is information for TV's “Jeopardy”, but it was the physicist Dominique Francois Jean Arago, born 50 years after the birth of another statesman/scientist – Ben Franklin.[Ref.1].
Some may remember from high school a demonstration called “Arago's disk”, wherein a copper or aluminum disc is spun underneath an ordinary compass, and the compass needle begins to swing round also. This is just one of the many experiments Arago did.
You had a lot to say on the WAMC listener comment line this week on everything from Joe Donohue's interview with Jesse Ventura, Republican Presidential Candidate Mitt Romney's '47 %' remarks, and several of our WAMC commentators. Segments of these comments ran Friday Sept. 21 on Midday Magazine and Northeast Report.
In the 19th century, Joseph Henry, first director of the Smithsonian, refused any salary increases, saying that public servants were there to serve, rather than to enrich themselves.
Now, there are two hospitals in Kingston NY – the Benedictine Hospital, a Catholic hospital (founded on its present site in 1906), and the non-sectarian Kingston hospital (founded in 1894), institutions in which, over the years, my family and I have had sundry procedures, such as appendix, hernias, and so on.
Settling into my seat on an Airbus, I wished that the 8-hour return from Europe could be more like 3 1/2 hours, as I'd heard the SSTs used to take.
Those SSTs -- Tupolevs and Concordes -- first flew in the late 60's. The Tupolev was first, in 1968, and then the Concordes in 1969. The latter went for 31 years without a crash – with the huge exception of the French Concorde that hit a piece of metal on the runway while taking off from Paris and crashed in flames, killing all on board.
In an earlier essay I mentioned that there was no reason why pure scientists such as myself shouldn't have a say in politics -- particularly since law-making is sometimes regarded, wrongly I believe, as being just in the province of those trained in law.
The word 'etiquette' reminds me of vicarage ladies discussing which way their pinkies ought to point when holding a tea-cup, but I use the word here with respect to the problem of friends who don't, can't or won't, respond.
I don't email much, and typically my 'you have mail' box may have anything between zero and three new emails each morning. I know people who apparently receive as many as 80 a day, excluding advertising! (How such a phenomenon occurs I'm not sure. They must be very talkative.)
There are at least two famous airlifts associated with World War II. In 1942, when the last route from India to China was cut off, FDR made the decision that it was imperative China receive armaments and supplies for the Army Air Force in China, which was struggling to pin down Japanese forces. Both the US and UK began the appallingly dangerous air lift over the Himalayas -- from Assam (famous for its tea) in India to Kunming in China.
