  STH209 - SCIENCE AND SOCIETY   (Site not responding. Last check: 2007-10-18)
Goethean science is therefore also a spiritual path, an integration of science and art, a science of quality and of wholeness, the development of a science of compassion.
Goethean science is an approach to knowing the world, that serves as an intuitive or "right brain" (so to speak) complement to the traditional rationalistic "left brain" science.
Fundamental to Goethe's approach to science was his insistence that the scientist is not a passive observer of an external universe, but rather engaged in a reciprocal, participatory relationship with nature, and hence the observer is able to interact with the observed.

 Revolution in Earth and Space Science Education - Brief History of Earth Science Education
While elements of geology, astronomy, physical geography, and environmental sciences were taught in schools at the turn of the 20th century, today's Earth science courses are a recent addition to K-12 education.
Science teaching at academies, however, was not always of high quality and often consisted of courses as short as six weeks, with inadequately prepared teachers and poor or non-existent textbooks.
The 219 remaining chapters were coded to match the four Earth science themes resulting in 120 chapters devoted to geology, 34 to meteorology, 23 to oceanography, and 42 to space sciences.

 Mars Pathfinder - Science Results Directory
The combination of spectral imaging of the landing area by the lander camera, chemical analyses aboard the rover, and close-up imaging of colors, textures and fabrics with the rover cameras offered the potential of identifying rocks (petrology and mineralogy).
The 3 instruments and rover allowed seven areas of scientific investigation: the geology and geomorphology of the surface, mineralogy and geochemistry of rocks and soils, physical properties of surface materials, magnetic properties of airborne dust, atmospheric science including aerosols, and rotational and orbital dynamics of Mars.
If the (iron-enriched) Shergottite meteorites are typical of the mantle composition, then the mantle must be warmer than Earth's (for the same pressure level) and the core radius must be larger than ~1300 km (but no larger than ~2000 km for other mantle compositions).

O Logic: born gatekeeper to the Temple of Science, victim of capricious destiny: doomed hitherto to be the drudge of pedants: come to the aid of thy master, Legislation.
Every science that has thriven has thriven upon its own symbols: logic, the only science which is admitted to have made no improvements in century after century, is the only one which has grown no symbols.
Every other science, even logic, especially in its early stages, is in danger of evaporating into airy nothingness, degenerating, as the Germans say, into an arachnoid film, spun from the stuff that dreams are made of.

 PLANETARY SCIENCE: AGAINST STANDING MARTIAN WATER
On the basis of these observations, the MER science team[1,2] has interpreted the bedrock as siliciclastic sediments deposited in a shallow body of briny water, with subsequent evaporation leaving behind sulphate minerals.
They inferred that the rocks are composed of roughly 50 wt% siliciclastic material derived from basaltic rocks, 40 wt% evaporite sulphates, and 10 wt% haematite[2].

 HEAL Toronto: Problems with HIV Science
Another major problem with AIDS science is that the official estimates for the number of people in the United States who are HIV positive have never actually resembled an epidemic.
Conventional science has focused narrowly on a search for genetic protective factors to explain their "resistance to the virus", while ignoring many survivors' own explanations for why they have remained healthy for so many years.
In many ways, "science" has replaced religion as the mediator between God/Nature and humanity, and people prefer to believe in the infallibility of science, much as Christians believed in the infallibility of the Pope.

 PLANETARY SCIENCE: ON THE INTERIOR OF MARS
Such a core dynamo may be driven either by compositional convection (which is set in motion by a composition gradient) in a liquid outer core due to solidification of an inner core, or by thermal convection in a fully liquid core due to high heat flux out of the core.
Tanaka, N. Isbell, D. Scott, R. Greeley, J. Guest, in Proceedings of the 18th Lunar and Planetary Science Conference, G. Ryder, Ed.
Mars is now a desert world on which liquid water, because of ambient conditions, is not likely to be found at the surface: average temperatures are below 273 degrees kelvin and atmospheric pressures are at or below water's triple-point vapor pressure of 6.1 millibars.

 Durban Declaration Rebuttal
It is widely known that 99.9% of the proviral DNA of HIV present in cells is defective and cannot lead to infectious, viable virus (Piatak, M., et al., Science 259: 1749-1754, 1993; Sheppard, H. et al., Nature 364: 291-292, 1993).
However, the PCR test cannot distinguish between the trace amount of non-infectious viral debris that overwhelms the even smaller level of proviral DNA that could lead to the production of viral particles under the special laboratory conditions of coculture.
Even coculturing techniques failed to find infectious HIV in 53% of samples that have PCR viral load numbers in the hundreds of thousands (Piatak, M., et al., Science 259: 1749-1754, 1993).

 NASA/Marshall Solar Physics
In 1610, shortly after viewing the sun with his new telescope, Galileo Galilei made the first European observations of Sunspots.
Daily observations were started at the Zurich Observatory in 1749 and with the addition of other observatories continuous observations were obtained starting in 1849.
The sunspot number is calculated by first counting the number of sunspot groups and then the number of individual sunspots.

Both Pluto and the new, so-called planet are found in the Kuiper Belt, a disc of icy bodies beyond Neptune.
In fact, about a fifth of the objects observed in the region have been found to have satellites, and the percentage could grow as more are found, said Keith Noll, an astronomer at the Baltimore-based Space Telescope Science Institute.
The institute coordinates use of the orbiting telescope, but Noll wasn't part of the Pluto team.

Public hostility to biotechnologies is usually attributed to a lack of "scientific literacy" on the part of citizens and, more in general, to a prejudicial skepticism toward science.
Using data from the third edition of a survey of Italian citizens, the authors of this Policy Forum argue that the key factor may not be straightforward hostility against biotechnologies or against science per se, but skepticism about the interaction among scientific expertise, decision-making, and political representation.
