theoretical physics. Our picture of the universe has changed a great deal in the

last 50 years and I'm happy if I have made a small contribution. The fact that

we humans who are ourselves mere collections of fundamental particles of

nature have been able to come as close to understanding of the laws

governing us and our universe is a great triumph. I want to share my excitement

and enthusiasm about this quest.

So remember to look up at the stars and not down at your feet

try to make sense of what you see and wonder about what makes the universe

exist be curious and however difficult life may seem there is always something

you can do and succeed at. It matters that you don't just give up.

Thank you for listening.
