was a lie detector expert, worked in the field of
for more than 20 years & also worked for CIA .
He spends most of his life in analyzing polygrams & charts & in polygraph
One day in the cold winter of 1966 in apartment follows CIA in times square,
Baxter felt bored after long concentration in reading & interpreting
polygrams (Lie Detectors Charts), so when he notice the plant in the corner of
his room, he thinks of using the electrical resistance electrodes (used to
detect sweating activity in humans by measuring the skin resistance increase
due to water of sweat which increases when the man stressed) to measure the
flow rate of water to the plant leaves.
So he fixed the 2 electrodes on thick leaf of the plant by a rubber tie,
then pour water in the container in which the plant grow, he followed the
movement of the pin over the paper coming out of the apparatus, what he found?
he finds that the vibration less than normal not more as he predicts it would
be due to the increase of water but he found that the chart is typical to a
chart of a man undergoing smooth emotional excitation (happiness?!!)
Then he thought what if he hurt the plant itself, in men any physical threat
get sharp emotional response and fear & anxiously appear on the chart, so
he thinks to put a leaf from the plant in his hot coffee, but unfortunately
nothing happened for 9 minutes.. So what? he then thinks to burn the side of the leaf on which the electrodes is
fixed, then a sudden large jump in the vibration appeared!!!!what is that? it
seems that the plant read his mind!!!! & when he burn the leaf it didn't
give much response like just thinking to hurt it, then he repeat the experiment
that he ensured that its true & then great amount of experiments were made
around this discovery.
