Today is
World Intellectual
Property Day. 1900: Seismologist
Charles
Richter, who devised the earthquake-measuring scale that bears his name, was
born. 1921: The first U.S. broadcast of the weather was made from St. Louis, MO,
station WEW. 1933:
Arno Penzias, who with Robert Wilson, won the Nobel Prize for
discovering the background microwave "Big Bang" radiation, was born. 1962: The
Ranger IV space probe became the first U.S. craft to land (a planned crash)
on the moon. 1986: The world's worst nuclear accident occurred at the
Chernobyl
plant in Pripet, Russia (formerly Soviet Union). 1989:
Lucille Ball
died (hard to believe so long ago).
Note: These
historical tidbits (see daily
list) have been collected from various sources, mostly on the Internet.
As detailed in my
It Happened When? Factoid article, there
is a lot of wrong information that is repeated hundreds of times because most websites
do not validate with authoritative sources. On RF Cafe, events with
hyperlinks have been verified. Many years ago,
I began commemorating the birthdays of notable people and events with
special RF Cafe logos.
Where available, I like to use images from postage stamps from the country where
the person or event occurred. Images used in the logos are often from open source
websites like Wikipedia, and are specifically credited with a hyperlink back to
the source where possible.
