More muddle over the Hubble constant
Article Abstract:
The value of the Hubble constant is a source of conflict among cosmologists because the value is essential for estimating the distance scale and age of the universe and yet no consistent value is accepted. Improvements in technology and the discovery of well-ordered happenings such as a Type 1a supernova explosion may make the expansion velocity increase rate between our galaxy and others, the definition of the Hubble constant, more trackable. However, general acceptance of a single value is unlikely to occur soon and so conflicts over issues such as the belief in the Big Bang will continue.

Time for tempting the Nobel fates
Article Abstract:
Possible winners of the 1992 Nobel prizes for physics, chemistry and physiology/medicine can be suggested based on the Stockholm committee's past behavior. For instance, the committee does not limit prizes to discoveries made in the preceding year. An award for finding a new technique such as the polymerase chain reaction is possible. However, the committee is unlikely to give an award for discovering the mechanism of gene control because too many people participated. Recent work on wave functions that may undermine quantum mechanics may merit an award.

Uncertainty in quantum theory
Article Abstract:
Scientists are trying to bridge the gap between deterministic wave mechanics and quantum mechanics. One reason for the misunderstanding of quantum mechanics arises from the lack of clarity in the embodiment of determinism in Schroedinger's quantum wave equation in 1926 and the common opinion that quantum mechanics is basically about uncertainty. Improvements in quantum mechanics through the efforts of Richard Feynman and Robert B. Griffiths are discussed.
