Scientifically speaking
A flash from the past can certainly help inform our thinking
today in a most scientific way!
Mesmerized: how Ben Franklin solved a mystery that baffled all of
France by Mara Rockliff tells of a time in 1776 when Ben Franklin
traveled to France to petition the King for money to support the American Revolution. While there, a Dr. Mesmer was creating a stir
in society by hypnotizing people. He
convinced people that plain water could taste like strawberries or vinegar; he
seemingly cured people of illnesses; and for a price he was willing to share
his secrets. Some in society were less than enthralled with Dr. Mesmer’s
ability and the King decided to have Ben Franklin assess these magical powers.
So using sound scientific reasoning, B.F. began his
assessment:
1. He observed Dr. Mesmer’s effect on
different patients and compared them to his own experience. (B.F. was unaffected.)
2. He hypothesized that patients were
convincing themselves of these changes and not by Dr. Mesmer’s invisible force.
3. By blindfolding the patients, B.F. was able to test
his hypothesis. Being unable to see the doctor meant patients couldn't tell
if the doctor was even in the room let alone waving his wand in an attempt to
hypnotize them.
4. The testing supported B.F.’s theory. He told the King his conclusions and
Dr. Mesmer left Paris.
This is the strength of this book. It takes a true
historical event and shows how science and scientific thinking was able to
solve a conundrum.
Additional information is provided that explains that the
placebo effect is credited to Dr. Mesmer.
We also learn that in France at the time of Ben Franklin’s visit, Paris was
agog with many new discoveries such as invisible gases (hydrogen and oxygen)
and the lift-off of a hot air balloon.
The French were impressed with B.F.’s own discoveries and inventions, making him somewhat of a celebrity. A few of the details of the story were
gently ‘massaged’ and the afterward credits other French scientists with assisting B.F.
I really enjoyed the illustrations, as well. Lots of play with fonts and sizing, pages
divided into panels, interesting perspectives, dynamic facial expressions, and
boxed information to clearly outline the process of testing a theory.
I highly recommend this for elementary grades.
But a word of caution --don't stare at the end papers too long, otherwise you may find yourself becoming sleepy, very, very sleepy....
