There is a better chance of seeing him on an episode of "Nova," bemoaning the fact that after centuries of studying the heavens, we still know so little about our existence.
Much is known of the detailed processes of vegetation modification along the Mediterranean, since they have been observed and studied since Classical times, and a good deal is also known from the more than three centuries of study of the Cape area of South Africa, but until the late 19th century very little was understood about these processes in tropical Africa.
Leon Golub and Jay M. Pasachoff offer an engaging and informative account of solar science and its history, drawing on centuries of study by solar astronomers who have looked to the Sun not only to learn about our own solar system but also about what lies in the distant wilderness of faintly glimmering stars.
Then there's the apparent fact that, after years and centuries of study, we have no clue as to what 96percentt of the universe consists of.
The phylogenetic affinity of Strepsiptera remains uncertain despite more than two centuries of study [e.g., 4,10,13 30].
As genome sequencing become both less expensive and easier to conduct (http://genome10k.soe.ucsc.edu/), such approaches will become available for more species, but the descendants of domesticated taxa will still have the advantage of centuries of study.
Unfortunately, nearly half a century of studies of stars indicates that the oldest stars in the Milky Way are at least 16 billion years old.
The natural histories of free-living and pathogenic protozoans have been described in over a century of studies, spanning a range of disciplines such as microscopic, cellular, taxonomic, pathological, clinical and molecular.
The impact structures have been the subject of more than half a century of studies and range from several tens of meter-large craters to buried structures larger than 100 km in diameter.
