The Evidence of Things Not Seen is a book-length essay by James Baldwin, published in 1985 by Holt, Rinehart and Winston. The book covers the Atlanta murders of 1979–1981 , often called the Atlanta child murders, and examines race relations and other social and cultural issues in Atlanta .
Evidence of Things Not Seen is quoted from Verse 1 of Hebrews 11. It may also refer to: Evidence of Things Not Seen (Gabriel Teodros album) Evidence of Things Not Seen (McCallum and Tarry), 2008 art installation; Evidence of Things Not Seen (song cycle), song cycle by Ned Rorem; Evidence of Things Not Seen (The West Wing), television episode
The discovery of these particles required very different experimental methods from that of their ordinary matter counterparts, and provided evidence that all particles had antiparticles—an idea that is fundamental to quantum field theory, the modern mathematical framework for particle physics. In the case of most subsequent particle ...
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
The phenomenon is studied by physics and perceptual psychology. Since objects can be seen by light from a source reflecting off their surfaces and hitting the viewer's eyes , the most natural form of invisibility (whether real or fictional) is an object that neither reflects nor absorbs light (that is, it allows light to pass through it).
As noted by Gregory Benford et al., special relativity implies that tachyons, if they existed, could be used to communicate backwards in time [2] (see tachyonic antitelephone). Because time travel is considered to be non-physical, tachyons are believed by physicists either not to exist, or else to be incapable of interacting with normal matter.
In physics, a unified field theory (UFT) is a type of field theory that allows all fundamental forces and elementary particles to be written in terms of a single type of field. According to modern discoveries in physics, forces are not transmitted directly between interacting objects but instead are described and interpreted by intermediary ...
The distinction between mathematics and physics is clear-cut, but not always obvious, especially in mathematical physics. Ontology is a prerequisite for physics, but not for mathematics. It means physics is ultimately concerned with descriptions of the real world, while mathematics is concerned with abstract patterns, even beyond the real world.
