What is the difference between knowledge and belief?

A belief requires trust. Knowledge requires justification.

The above is a belief that may be justified.

This thread was full of examples of many people holding many beliefs without any knowledge.

It is ironic that the "believer" often claims a certainty that those who pursue knowledge do not aspire to. The "knower" is much less attached to his object of knowledge, while the believer seems to be absolutely attached to his.
For a knower it is meaningless, for example, to die for something like a mathematical computation that others object to. Knowers are more likely to be open to correction, but believers might resist it sometimes with their lives.
Sorry, my "ideal types" have the fault of caricatures, but you judge if in your experience they carry some truth.

I know what I believe, but what I believe I do not know.

Sometimes what I know, I truly only believe.
