A Quote by Marcus du Sautoy
Theory is needed to tell you where to look.

The aim of academic trade theory is to tell students, "Look at the model, not at how nations actually develop." So of all the branches of economic theory, trade theory is the most wrongheaded.
I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.
It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.
When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.
Men follow their sentiments and their self-interest, but it pleases them to imagine that they follow reason. And so they look for, and always find, some theory which, a posteriori, makes their actions appear to be logical. If that theory could be demolished scientifically, the only result would be that another theory would be substituted for the first one, and for the same purpose.
When I look at the patients that I've cared for with mental illness, I know that many of them took years to come forward and tell somebody that they were in pain and that they needed help.
If Christianity needed an Anti-Christ, they needed look no farther than Paul.
If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.
We are caught up in a paradox, one which might be called the paradox of conceptualization. The proper concepts are needed to formulate a good theory, but we need a good theory to arrive at the proper concepts.
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.
If you're a physicist, for heaven's sake, and here is the experiment, and you have a theory, and the theory doesn't agree with the experiment, then you have to cut out the theory. You were wrong with the theory.
A thing may look specious in theory, and yet be ruinous in practice; a thing may look evil in theory, and yet be in practice excellent.
Almost all the other fellows do not look from the facts to the theory but from the theory to the facts; they cannot get out of the network of already accepted concepts; instead, comically, they only wriggle about inside.
I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.
The mindset that is needed, the capabilities that are needed, the metrics that are needed, the whole culture that is needed for discontinuous innovation, are fundamentally different.
No theory changes what it is a theory about. Nothing is changed because we look at it, talk about it, or analyze it in a new way. Keats drank confusion to Newton for analyzing the rainbow, but the rainbow remained as beautiful as ever and became for many even more beautiful. Man has not changed because we look at him, talk about him, and analyze him scientifically. ... What does change is our chance of doing something about the subject of a theory. Newton's analysis of the light in a rainbow was a step in the direction of the laser.
