Dr. Jahn is the founder of PEAR
(Princeton Engineering Anomalies Research). http://www.princeton.edu/~pear/
From that site:
"The enormous databases produced by PEAR provide clear evidence that
human thought and emotion can produce measureable influences on
physical reality. The researchers have also developed several
theoretical models that attempt to accommodate the empirical results,
which cannot be explained by any currently recognized scientific
model."
Here is one of his articles that I found interesting: http://www.princeton.edu/~pear/pdfs/jahn15_4.pdf
where he discusses scientific problems and models.
