A new laboratory—How to work in it
The techniques of basic research in the space program, once primarily of geophysical interest, are finding new applications in other scientific areas. The question treated here is what promise do they hold for an experimental science like physics?
The structure of nucleons
…with the examination of the structure of the proton and neutron one is investigating a new hierarchical level in the material organization of the physical universe, related to, but underlying, the now substantially explored level of atomic and nuclear structure…
Plutonium criticality experiments
For both reactor design and safety in nuclear‐fuel processing, one needs to know masses, concentrations, and dimensions of critical plutonium systems. Behavior is similar to that of uranium, but different enough that extrapolation is difficult and experiments are necessary. Experiments at a Hanford facility have examined criticality in water solutions and plutonium assemblies.
Eclipse
The total eclipse of the sun on May 30, 1965, was observed by scientific investigators from many nations from vantage points along a path sweeping across the Pacific Ocean. The present account was written by a member of the expedition to Bellingshausen, a South Pacific atoll in the Society Islands group.
