Cassini, Jacques: dates as given on a
page of the Paris Observatory. Because generations of the Cassini family
were astronomers there, those dates have been taken to be definitive. However,
Britannica gives 8 Feb 1677 - 18 April 1756, and the
of Scientific Biography gives 18 Feb 1677 - 15 Apr 1756. The Paris
Observatory history states that Jacques Cassini was injured when his carriage
overturned on 15 Apr 1756, and that he died the next day, on the 16th.

Crop-dusting: first time event date from
"Fighting Insects with Airplanes" by C.R. Nelly and J.S. Houser, National
Geographic Magazine, Vol. 41, pages 333-8 (Mar 1922). [Notes:
The article is subtitled An Account of the Successful Use of the Flying
Machine in Dusting Tall Trees Infested With Leaf-Eating Caterpillars. C.R.
Nelly is the entomologist that suggested the idea, so when he wrote the
article, he was probably well aware of the correct date for the event.
The date, and a mention of that article, is given in Seeds
of Change: A History of the Ohio Agricultural Research and Development
Center, by Christopher M. Cumo, Wooster Book Co.(1999). However,
in the book John
Macready - Aviation Pioneer: At the Earth's Ceiling, by Sally Macready
Wallace, Sunflower University Press (Sep 1998), the date is given as 31
Aug 1921. The author is the daughter of the pilot, and wrote the book from
interviews with her father. All the preceeding sources state lead arsenate
as the chemical used. A New York Times article on 8 Jan 1922, p.85,
states the use of calcium arsenate as the chemical, which was mentioned
earlier in the article as proposed for use on cotton boll weevils.]

Pelletron: maximum voltage of 32.0 MV verified
by National Electrostatics Corporation (email, 8 May 2006). A previously
stated value of 321.5 MV is a typographical error which should instead
read 32 MV (+/- 1.5 MV) where +/-1.5 MV represents a 5% uncertainty in
the measurement. Also, the date was previously listed as 17 May 1979, and
has been corrected to Thursday, 10 May 1979. The terminal potential of
32.0 MV has been accepted as the world's highest by the Guinness Book of
World Records. The Pelletron accelerator model 25 URC remains the only
electrostatic accelerator capable of running above 20 MV routinely. In
the late 1970's an attempt was made by the UK government to build
a 30 MV tandem. That tandem suffered structural damage when attempting
to run above 20 MV, was shut down and removed. Another attempte was made
by the French government in the mid 1980's to build a 35 MV tandem accelerator.
Those attempts failed with structural damage occurring in the region of
18 to 22 MV. That system has also recently been shut down.
