The Bridge Blog
A dialog about our new bridge and these web pages
Overview.
Schools and universities are all about learning - and learning is mostlly
brain training. Learning is expedited by repetition and forgetting
is expedited by infrequent use of learned skills or information.
Tracking the building of the Ravenel Bridge and now tracking the
demolition of the Grace and Pearman Bridges bring
many questions to me and help me better understand the role Google
and the Internet play in
just-in-time learning. I enjoy chasing my curiosity and
want to identify ways to encourage younger learners to also enjoy curiosity
chasing and learning.
Many young learners do not understand the importance of repetition. More
important, while experienced learners understand the learning process
they often do not realize the destructive effects of the forgetting
process. Over the course of the
bridge project, I have access to only a few experts.
Rather than a liability, this has become an asset and pushed me to improve
my search skills with Google. Soon, I realized that answers
to questions encountered during my photo adventures were often
only a Google-search away. Gene Stead,
my first boss and I put these ideas together in a small essay:
(see
Restoring the Joy in Learning).
Google + Internet have become dependable extensions of my memory.
Insights I gain from you and this project will find their way into the
learning centers in our schools and universities.

September 14, 2005: Fixing the Grace Bridge
Lee Graves in Tomball Texas found our web site and contributed
the following story from his father, James R. Graves, senior
designer of the Pearman Bridge.
"I recently discovered your website showing the "unbuilding" of the old
bridges. My father, James R. Graves, was the senior designer of the old
Pearman bridge so I feel a real connection with the two bridges. Several
years later he was made Bridge Engineer of the SC Highway Department. You
probably do not know a very interestoing story regarding the old Grace
bridge. During construction of the Pearman bridge, it was discovered that
the old timber pilings supporting the first pier of the old bridge on the
Charleston side were virtually eaten away by marine worms and the old bridge
was in real danger of collapsing, and in fact the old bridge was leaning
several feet out of plumb. It was decided to put a cable around the old
pier, pull it back into alignment, and pour a concrete casing around the
remains of the timber pilings. When the old bridge is demolished down to
the piers, you might take a close look at the footing of that first pier."
And just to keep life interesting - here is today's projection of
Hurricane Ophelia. Ophelia has been just sort of chillin' out a bit - about
150 miles east of Charleston. NOAA provides a very useful service with
their projections and advisories. I've included these on the main bridge
web page. We have a more compresensive
aggregation of weather related
images at MUSC.
