Later, I developed a broader theory of what separates the two general classes of learners—helpless versus mastery-oriented.

I realized these different types of students not only explain their failures differently, but they also hold different theories of intelligence.

Albert Einstein predicted this in 1905, when he introduced the concept of relative time as part of his Special Theory of Relativity.

It enables him to apply theory to practice.

Now what’s interesting about the theory is what do you have if you only have one out of three or two out of three? What do you have and how is it different if you have a different two out of three? What’s interesting about this kind of theorizing is it gives rise to many different combinations that can be quite interesting when you break them down and start to look at them carefully.

And he has a theory of love that argues that it’s made up of three components: intimacy,passion and commitment, or what is sometimes called decision commitment.

The central notion of social learning theories is that people learn attitudes, beliefs, and behaviors through social interaction.

It will take another Einstein to build a unified theory

His solid foundation in math theory.

Nobody will read papers on apparently ridiculous theories.

Kathy, chaos theory seems to be a branch of physics or mathematics.

Chaos theory was developed by scientists, trying to explain the movement of the planets and the changes in environmental conditions

In the 1990s, many economists began to look at chaos theory as a way of providing models for forecasting.

Well, that's a good question, because the basic idea of chaos theory is that there aren't any "models" as such— there aren't guaranteed forms, but rather patterns of change in development

What was chaos theory supposed to do when it was first formulated?

Chaos theory and its applications

"In theory," says Vallentine, "this can create a high enough temperature to generate super-heated steam.

And he has a theory of love that argues that it's made up of three components: intimacy,passion and commitment, or what is sometimes called decision commitment.

The third element of love in Sternberg's theory is what he calls decision commitment, the decision that one is in a love relationship, the willingness to label it as such and the commitment to maintain that relationship at least for some period of time.

You see it in faculty members who are pleased when their students make a discovery that undermines a cherished theory that they had put forward.
