George and Charlotte Blonsky, who were a
-
Not Synced
married couple living in the Bronx in New York City,
-
Not Synced
invented something.
-
Not Synced
They got a patent in 1965,
-
Not Synced
for what they call,
-
Not Synced
"a device to assist women in giving birth."
-
Not Synced
This device consists of a large, round table
-
Not Synced
and some machinery.
-
Not Synced
When the women is ready to deliver her child,
-
Not Synced
she lies on her back,
-
Not Synced
she is strapped down to the table,
-
Not Synced
and the table is rotated at high speed.
-
Not Synced
The child comes flying out
-
Not Synced
through centrifugal force.
-
Not Synced
If you look at their patent carefully,
-
Not Synced
especially if you have any engineering background
-
Not Synced
or talent,
-
Not Synced
You may decide that you see
-
Not Synced
one or two points where the design is not
-
Not Synced
perfectly adequate.

Doctor Ivan Schwab in California
-
Not Synced
is one of the people,
one of the main people
-
Not Synced
who helped answer the question,
-
Not Synced
"Why don't woodpeckers get headaches?"
-
Not Synced
And it turns out the answer to that
-
Not Synced
is because their brains
-
Not Synced
are packaged inside their skulls
-
Not Synced
in a way different from the way
-
Not Synced
our brains, we being human beings,
-
Not Synced
true, have our brains packaged.
-
Not Synced
They, the woodpeckers, typically
-
Not Synced
will peck, they will bang their head
-
Not Synced
on a piece of wood thousands of times
-
Not Synced
everyday.
-
Not Synced
Everyday.
-
Not Synced
And as far as anyone knows,
-
Not Synced
that doesn't bother them
