Fundamental Questions in Science

An issue devoted to science in its strict sense: the interrogation of nature. This introduction raises the question: Does our society confuse science with applied science, and thus neglect the former?

By Warren Weaver

What is Matter?

The wave-particle dualism afflicting modern physics is best resolved in favor of waves, believes the author, but there is no clear picture of matter on which physicists can agree

By Erwin Schrödinger

What Holds the Nucleus Together?

Electrical forces bind the electron to the atom, but they cause nuclear particles to fly apart. The powerful cohesion of protons and neutrons must be explained by a wholly different phenomenon

By Cecilia H. Payne-Gaposchkin

How is a Protein made?

These giant molecules are constructed in fantastic variety out of 22 amino acids. The mechanism of their synthesis is perhaps the greatest challenge facing the modern biochemist

By K. U. Linderstrom-Lang

How do Cells Differentiate?

An unspecialized egg gives rise to all the specialized tissues of an organism. The study of this marvelous phenomenon engages two disciplines of the modern biology: embryology and genetics

By C. H. Waddington

What is Memory?

The means by which the brain stores the rich variety of human experience is completely unknown. The nerve physiologist tries to apprehend the mechanism with cleverly designed experiments

By Ralph W. Gerard

Some mathematicians argue that it is "statistical"; others, that it is "inductive." The author believes that there are two kinds, both essential to the future progress of science
