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.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

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.

There could be no fairer destiny for any physical theory than that it should point the way to a more comprehensive theory in which it lives on as a limiting case.

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.

String Theory describes energy and matter as being composed of tiny, wiggling strands of energy that look like strings. And the pitch of a string's vibration determines the nature of its effect.

Whichever theory we adopt to give a rational explanation of human existence, that theory must take into account and explain the mental nature we see at work in all modern communities.

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.

Louis' Theory
The freedom of the mind is like,
The freedom of a speech;
But on the table is a bowl of cherries to Archipelagos!
I have the freedom of my theory to all mankind.
Oh freedom!
Of a philosophical conundrums to share with you;
For my theory is for ages in times like war without peace!
From the freedom of a philosophical point of view,
Like the summer and winter when lovers do meet;
But i do have my mind on you always.
I am like a wanted person with an unknown identity,
I write and many dop not understand;
But like the freedom of a philosophical theory,
I have my visions to the wider threshold across the line of a battle.
Oh freedom!
To boost up my ego;
Like a rainbow shell on my theory,
But this is part of my joy at peace on this earth.
Like the way of life to all mankind,
I am to fulfil a dream on this philosophical ideas;
But the 'Louis' Theory' is all about numbers!
And the secret code is '6-5-6'.
This deals with the ages of man's life on this earth,
Like the tales of the Gurkhas in Ghana;
But, '6-5-6' has a lot to tell and explain.

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.

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science.

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

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.

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.
