What was Pasteur's contribution to experimental science?
Pasteur’s work on fermentation and spontaneous generation were central cases in Conant’s course. The texts were eventually published in Harvard Case Studies in Experimental Science (Conant and Nash 1957 ), a book that stimulated the new social approach to science studies that emerged in the 1960s.
What was the manipulated variable in Pasteur's experiment?
The manipulated variable was the presence or absence of the gauze covering, and the responding variable was whether maggots appear. What is the control group in Pasteur’s experiment?
Did Pasteur induce chirality with a magnetic field?
The presence of a strong peak at 235 nm in the magnetochiral absorption spectrum of tartrates shows that Pasteur's first attempt to induce chirality with a magnetic field could perhaps have succeeded, provided that a UV source was simultaneously used. To cite this article: T. Ruchon et al., C. R. Physique 5 (2004).
How did Pasteur prove heterogenesis?
Pasteur’s chance to intervene came in 1876 when Bastian published a new experiment to prove heterogenesis: If a suitable amount of sterile potash solution was added to sterile urine and the medium kept at ca. 50 °C, fermentation with bacteria rapidly occurred.
