Two lines must meet at a point. Therefore there are only two surprises here.

What will the greatest experiment discover? I have no idea!, maybe nothing!, If we won't check, we will never know. In science there is never a guarantee of success. If you understood this last sentence, then you understood the most important message of this lecture.

This is a rather unusual situation in physics. We perform approximate calculations which are valid only in some regime and this gives us the exact answer. This is a theorist's heaven- exact results with approximate methods.

We do not know how to formulate string theory nor do we know its underlying principles. Surprisingly, this fact does not stop us from making progress.

I am almost certain that space and time are illusions. These are primitive notions that will be replaced by something more sophisticated.

The standard model gives us an accuracy of ten decimal digits, this is an amazing success that has never been achieved before in science.
