I finished reading Stephen Greenblatt’s book, The Swerve: How the World Became Modern, this week.  It inspired this morning’s poem on my daily poem project, Writing the Day.

Ghost Heart

Ghost heart image by Doris Taylor

Right now, more than 3,200 people are on the waiting list for a heart transplant in the United States. And other s are hoping for replacement kidneys, livers, lungs, and pancreases. We need spare parts.

Some of those waiting won’t make it, because an appropriate match won’t be available in time. Some will get a transplant, but it will be rejected by their body.…

"There once was a ripple in space
That grew at incredible pace
Now close observation
Reveals this inflation
Has left an indelible trace."

— Limerick poet Mick Twister rhymes yesterday’s news that physicists had observed gravitational waves, strong proof that cosmic inflation occurred in the earliest moments of our universe.

New Moon, Black Moon

New Moon, Black Moon

There was no New Moon this month, but there will be two in March – on the 1st and the 30th.

I have seen some websites call the New Moon a Black Moon. That is not an astronomical term but the name is understandable since the Moon is not normally visible at this phase (except when it is seen in silhouette during a solar eclipse).

It’s All In How We Ask the Questions

I never lose sleep worrying about light. Is it a particle or a wave? It has a very lovely split personality.

sci-universe: These footprints, found on England’s eastern coast, are more than 780,000 years old. They are the earliest human footprints that have been found outside of Africa.
The footprints were discovered in Happisburg, Norfolk last May, have been uncovered by a team of scientists led by Queen Mary University of London, the British Museum and the Natural History Museum. A  study published Februry 7 in the journal Plos One describes the find and the species believed to have left them.

The ancient mud where the footprints were preserved has been dated to between 780,000 and one million years ago.

The oldest known footprints are preserved in volcanic ash at Laetoli in Tanzania, and are 3.66 million years old.

Finnish research team reveals how emotions are mapped in the body
Researchers found that the most common emotions trigger strong bodily sensations, and the bodily maps of these sensations were topographically different for different emotions. The sensation patterns were, however, consistent across different West European and East Asian cultures, highlighting that emotions and their corresponding bodily sensation patterns have a biological basis.
The findings have major implications for our understanding of the functions of emotions and their bodily basis. On the other hand, the results help us to understand different emotional disorders and provide novel tools for their diagnosis.
The image shows how body maps indicate the regions whose activation increased (warm colors) or decreased (cool colors) when feeling each emotion.

Today is Sir Isaac Newton’s bithday. I was looking up at the Moon tonight and trying to see what he might have seen.
He wrote, “I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.”
