At What Time were the Galapagos Islands Discovered?

Life in the Galapagos Islands

Estrogens and other endocrine disrupting compounds (EDCs) in the environment present a unique problem for environmental health. As an unregulated class of compounds, an accurate assessment of whether estrogens are present in the environment is critical. Current Environmental Protections Agency (EPA) standards for the analysis of organic molecules in water rely on removal of the compounds via li...

Potassium-argon ages from the galapagos islands.

Potassium-argon ages of eight volcanic rocks from some of the geologically oldest flows exposed in the Galápagos Archipelago indicate that the Galápagos Islands have a probable maximum age of 3 million years. Rocks from six islands were dated; the oldest are from Española (3.2 +/- 0.2), Sante Fe (2.7 +/- 0.1), and Plazas (4.2 +/- 1.8 million years). The new data suggest that the Galápagos Islan...

How Were the Hilbert–einstein Equations Discovered?

The pathways along which A. Einstein and D. Hilbert independently came to the gravitational field equations are traced. Some of the papers that assert a point of view on the history of the derivation of the gravitational field equations “that radically differs from the standard point of view” are critically analyzed. It is shown that the conclusions drawn in these papers are completely groundless.
