On November 8, 1895, physicist Wilhelm Conrad Röntgen 
(1845-1923) became the first person to observe X-rays, a
significant scientific advancement that would ultimately
benefit a variety of fields, most of all medicine, by making
the invisible visible.

Röntgen’s discovery occurred accidentally in his Wurzburg,
Germany, lab, where he was testing whether cathode rays
could pass through glass when he noticed a glow coming
from a nearby chemically coated screen. He dubbed the rays
that caused this glow X-rays because of their unknown nature.

The crater lies on the south end of Inver Grove Heights, near
the Mississippi River.

(Fox News) – University of Minnesota researchers have discovered
an ancient crater lying 350 feet below a Mississippi River suburb.

A team of scientists at the Minnesota Geological Survey (MGS) –
part of the university’s College of Science and Engineering’s
School of Earth and Environmental Sciences – discovered the
crater while updating a geologic map of Dakota County; the
county borders Minneapolis and St. Paul. 

For reference, researchers say they believe this crater would be
11 times the size of the famous Meteor Crater in Arizona. They
say it appears the massive meteor struck the earth around 490
million years ago, putting it near the end of the Cambrian period.

Sir Alexander Fleming  (6 August 1881 – 11 March 1955)

Sir Alexander Fleming was a young bacteriologist when an
accidental discovery led to one of the great developments
of modern medicine on September 3, 1928. Having left a
plate of staphylococcus bacteria uncovered, Fleming noticed
that a mold that had fallen on the culture had killed many of
the bacteria. He identified the mold as penicillium notatum,
similar to the kind found on bread.

In 1929, Fleming introduced his mold by-product called
penicillin to cure bacterial infections.

KENT COUNTY, Mich. (WWMT) — A construction project turned
into a dig site after road crews uncovered mastodon bones last
week in Michigan.

Crews were working on the Geers Intercounty drain construction
project in Newaygo when Drain Commissioner Ken Yonker said
an orange tint in the soupy mud had the team growing suspicious
that it could be bones.

Dr. Redman said the bones are expected to be on view at the
Grand  Rapids Public Museum, but the conservation process
could take up to 1 1/2 years until they’re ready for display.

The museum is working with the University of Michigan’s
Museum of Paleontology to continue studying the bones.

British archaeologist Howard Carter and his workmen discovered
a step leading to the tomb of King Tutankhamen in the Valley of
the Kings in Egypt on November 4, 1922.

When Carter first arrived in Egypt in 1891, most of the ancient
Egyptian tombs had been discovered, though the little-known
King Tutankhamen, who had died when he was 18, was still
unaccounted for. After World War I, Carter began an intensive
search for “King Tut’s Tomb,” finally finding steps to the burial
room hidden in the debris near the entrance of the nearby tomb
of King Ramses VI in the Valley of the Kings. On November 26,
1922, Carter and fellow archaeologist Lord Carnarvon entered
the interior chambers of the tomb, finding them miraculously
intact.
