Modern construction


 The local Amish had a barn raising last week during which 75 workers constructed a 96 foot long by 60 foot wide barn and an adjoining 40x24 foot room. Total time? Less than 8 hours..."The men started at 7am and by lunch time most of it was done. They expected to be finished by 3pm."

     “The first Kinzua Railroad Bridge was built by a crew of 40 from 1,552 short tons (1,408 t) of wrought iron in just 94 working days, between May 10 and August 29, 1882. The reason for the short construction time was that scaffolding was not used in the bridge's construction; instead a gin pole was used to build the first tower, then a traveling crane was built atop it and used in building the second tower. The process was then repeated across all 20 towers.
        Meanwhile in Warren the concrete bridge along the two lane main road is being replaced...(with modern power equipment assistance)...Construction began in early May and is projected to be finished in mid-September...over four months..I guess readers can see my point-there seems to be no will for efficient work.

Iranian Nukes

    ~ Despite what the war and fear mongers and other protesters who likely have not even read the Iran nuclear deal say, scientists are the people I prefer to put my trust in regarding such matters. I have read the books and articles of some of the signatories mentioned below and know them to be smart, thoughtful people. It is hard to comprehend the level of ignorance and small mindedness in many of our political leaders, but I suppose that politics in general attracts a certain personality type which does not often include our best minds...The following is from the NY Times:
   "Twenty-nine of the nation’s top scientists — including Nobel laureates, veteran makers of nuclear arms and former White House science advisers — wrote to President Obama on Saturday to praise the Iran deal, calling it innovative and stringent.
The letter, from some of the world’s most knowledgeable experts in the fields of nuclear weapons and arms control, arrives as Mr. Obama is lobbying Congress, the American public and the nation’s allies to support the agreement.
The two-page letter may give the White House arguments a boost after the blow Mr. Obama suffered on Thursday when Senator Chuck Schumer of New York, a Democrat and among the most influential Jewish voices in Congress announced he would oppose the deal, which calls for Iran to curb its nuclear program and allow inspections in return for an end to international oil and financial sanctions.
The first signature on the letter is from Richard L. Garwin, a physicist who helped design the world’s first hydrogen bomb and has long advised Washington on nuclear weapons and arms control. He is among the last living physicists who helped usher in the nuclear age. Also signing is Siegfried S. Hecker, a Stanford professor who, from 1986 to 1997, directed the Los Alamos weapons laboratory...
      Other prominent signatories include Freeman Dyson of Princeton, Sidney Drell of Stanford and Rush D. Holt, a physicist and former member of Congress who now leads the American Association for the Advancement of Science, the world’s largest general scientific society.
Most of the 29 who signed the letter are physicists, and many of them have held what the government calls Q clearances — granting access to a special category of secret information that bears on the design of nuclear arms and is considered equivalent to the military’s top secret security clearance.
Many of them have advised Congress, the White House or federal agencies over the decades. For instance, Frank von Hippel, a Princeton physicist, served as assistant director for national security in the White House Office of Science and Technology Policy during the Clinton administration.
The five Nobel laureates who signed are Leon N. Cooper of Brown University; Sheldon L. Glashow of Boston University; David Gross of the University of California, Santa Barbara; Burton Richter of Stanford; and Frank Wilczek of the Massachusetts Institute of Technology.
The letter uses the words “innovative” and “stringent” more than a half-dozen times, saying, for instance, that the Iran accord has “more stringent constraints than any previously negotiated nonproliferation framework.”
