From Remembering miss Meitner by Robert Marc
Friedman played during INPC2004, Göteborg, June
27- July 2 2004.
...How could one woman stop them? The future was
theirs. By then science was no longer what it had
once been. Money, fame, prizes, and intrigues
that was not what I devoted my life to. I gladly
gave up much for that which I love most. Physics
is my great love. My only love. It is the work
itself to work together, to be part of a
community. What matters most is the beauty of the
results the respect we share. I would do it all
over again and again and again. I am lucky. I
participated in a great adventure. to research
to discover And I became a snow angel!
Inger Hayman as Lise Meitner
