Evolutionary theory tends to explain quite well in retrospect how various species emerged. It's not very good on prediction. Nevertheless, one cannot say that there isn't a lot of knowledge that's been obtained in this field. In the same way, with these complex physical phenomena between solid state physics, you can say a lot of things without necessarily knowing the next step.

When one's subtle body travels outside of the physical body during the dream state, this experience is sometimes referred to as lucid dreaming. When metaphysicians are able to do this at will, the phenomenon is called astral projection or astral traveling: the ability to consciously leave the physical body and project the subtle body beyond its physical limitations.

There are in fact four very significant stumbling blocks in the way of grasping the truth, which hinder every man however learned, and scarcely allow anyone to win a clear title to wisdom, namely, the example of weak and unworthy authority, longstanding custom, the feeling of the ignorant crowd, and the hiding of our own ignorance while making a display of our apparent knowledge.
Roger Bacon
Can any rational person believe that the Bible is anything but a human document? We now know pretty well where the various books came from, and about when they were written. We know that they were written by human beings who had no knowledge of science, little knowledge of life, and were influenced by the barbarous morality of primitive times, and were grossly ignorant of most things that men know today.

A good deal of my research in physics has consisted in not setting out to solve some particular problem, but simply examining mathematical equations of a kind that physicists use and trying to fit them together in an interesting way, regardless of any application that the work may have. It is simply a search for pretty mathematics. It may turn out later to have an application. Then one has good luck. At age 78.
Paul Dirac
There is much to be said in favor of modern journalism. By giving us the opinions of the uneducated, it keeps us in touch with the ignorance of the community. By carefully chronicling the current events of contemporary life, it shows us of what very little importance such events really are. By invariably discussing the unnecessary, it makes us understand what things are requisite for culture, and what are not.
