In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature.

Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions.

The theory has to be interpreted that extra dimensions beyond the ordinary four dimensions the three spatial dimensions plus time are sufficiently small that they haven't been observed yet.

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways.

As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.

If diffraction or interference phenomena were to be sought it was therefore necessary, in accordance with the basic principles of wave theory, to select for the test arrangement far smaller decisive dimensions than those employed in corresponding tests with visible light.

I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.

Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.

A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.

Facing Up
Why do you wish to live in an ideal world?
Why do you think, that God will always be there?
Is it so hard to see things like they are?
Maybe one day, you'll stop living in a dream
Maybe not
Why religion, or magic or anything else?
What do you mean, love is not all we need?
Is it so hard to look at death every day?
Maybe one day, you may say this is for real
Maybe not
Facing up
Maybe not
Facing up
What if not?
So many problems of science involved
Complexity and basic principles
Observations of the empty space
Still searching for the final theory
Yeah the final theory
About our fate
Destiny
The dark energy
Facing up
Maybe not
Facing up
What if not?

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

Today the theory of evolution is about as much open to doubt as the theory that the earth goes round the sun.

Don't confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.

They didn't accept me theory - not a theory, but just a thought I had about this character. I noticed that this man only exists when the boy comes into the grocery.
