I was on acid and I looked at the trees and I realized that they all came to points, and the little branches came to points, and the houses came to point. I thought, 'Oh! Everything has a point, and if it doesn't, then there's a point to it.'

I do believe that most men live lives of quiet desperation. For despair, optimism is the only practical solution. Hope is practical. Because eliminate that and it's pretty scary. Hope at least gives you the option of living.

I get nervous when they start shooting piano players.

That incident ruined my reputation for 10 years. Get one Beatle drunk and look what happens!

It was just a typical London flat, but it was in a great neighborhood. It was across from the Playboy Club, diagonally. From one balcony you could read the time from Big Ben, and from the other balcony you could watch the bunnies go up and down.

For the animals, they came from the University in Uppsala and all different kinds of clinics here.

And I remember that the editors wanted to have a witness to say that this was really the case, because it was a very sharp picture of the just the face, the head of the fetus inside the womb.

And my real enemy is not to hold the specimen sterile, but it's the lighting. The light is our real enemy. So we have to work with very very poor lighting. But we can increase the light with computers.

I have many times thought I did the wrong thing, but the reason was not to be a medical doctor - it was just to have the information. But then, maybe I was wrong, I don't know.

I have some friends, colleagues here at the Karolinska Institute and even in the United States and many other countries too, because we are working together as scientists.

I have the instruments, ideas, technology, computer techniques. We try to create or see something, which has not been known before - just to discover something together. This is always my dream.

It's to surprise people about something that is extremely well known. I mean human reproduction, the human body, nature and so on. To surprise them with a new technique.

Of course, today at the Karolinska Institute, I am working with some top experts - even some Nobel prize winners. They have the latest news and I have the technique.

That's the new way - with computers, computers, computers. That's the way we can have the cell survive and get some new information in high resolution. We started about five years ago and, today, I think we have reached the target.

The chemistry of love is something which is extremely extremely unbelievable. This is something we have planned for more than two years, so I hope that we are going to start in the beginning of next year.

There is a new way with very very tiny fiber optics, which give an enormous high resolution. There are many many thousand fibers, very very close together with a very small diameter.

We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.

You know, of course, the specimens are not alive. We have to fix them in a fixing liquid formaldehyde and then we have to do a rinsing and then we have to coat them in a thin layer of gold.
