Julius von Mayer was a doctor and physicist who discovered that energy is conserved by studying his patients on an ocean voyage. James Prescott Joule was a physicist who also discovered that energy is conserved in an experiment with weights and a paddle in water. How does this illustrate the relationship between multiple approaches and the same result?
Answer
A
Scientists do not need to work in the same discipline to reach the same conclusion.
B
Scientists must be able to understand multiple disciplines.
C
Scientists in different disciplines do not all need to gather data.
D
Scientists must use very different experiments.
Explanation
Mayer studied his patients during an ocean voyage, while Joule used weights and a paddle in water. Though they used different approaches and came from different fields, both reached the same conclusion: energy is conserved. This illustrates that scientists can reach the same conclusion without working in the same discipline.
