Feature
Well, sadly, we’re back from our
vacation in Ireland. It was too short, but we had a
lovely time. Not a drop of rain the entire time that we were
there.
I was even exposed to a wee bit of
science during our travels.
While rushing through the Dublin airport, on our way flight
home, we passed a wall of murals depicting famous Irish scientists.
Unfortunately, I didn’t have time to stop and read them. But,
upon returning home, I did a Google search and found what
I missed.
While I was in Ireland, there was a piece on
TV about John Phillip
Holland. He was a monk who later became the
Father of the Modern Submarine. See Pat
Friend’s --- John
Holland - Submarine Inventor.
Ireland is steeped in over 5,000
years of history. The entire country seems to be covered with
ruins of castles, monasteries, ring forts and tombs of various
types.
One of the most interesting
types of tombs that we saw was the Megalithic Passage Tombs.
We visited the Knowth Passage Tombs in County Meath,
which is near the reconstructed tomb at Newgrange. See The Winter Solstice at Newgrange.
The entire country seems to be covered with Rhododendrons. They are quite striking
in their vivid colors. Unfortunately, they are an invasive species. See:
