Question

The famous scientist Albert Einstein sometimes used "thought experiments" such as imagining himself chasing a beam of light or riding in an elevator in free-fall. These thought experiments, which would not be possible to conduct physically, helped him challenge current scientific thinking and develop his theories of gravity and of special relativity. Write the words or phrases from the box on the lines to complete the paragraph. avoid errors hypothesis revised sample size select equipment statistical analysis

In actual physical experiments, scientists must __________ carefully and __________ in data collection and analysis.

a) Hypothesize; revise
b) Select; avoid errors
c) Statistical analysis; equipment
d) Sample size; choose

Answer 1

In actual physical experiments, scientists must select equipment carefully and avoid errors in data collection and analysis, underscoring the importance of meticulous approach in scientific experimentation.

Step-by-step explanation:

The thought experiments conducted by Albert Einstein, such as imagining himself chasing a beam of light or riding in an elevator in free-fall, played a crucial role in challenging the prevailing scientific thinking and paved the way for his groundbreaking theories of gravity and special relativity. In the course of actual physical experiments, unlike thought experiments, scientists must select equipment carefully and avoid errors in data collection and analysis. Einstein's ability to conceptualize and analyze scenarios that were not physically possible to test emphasized the importance of clear thinking and careful analysis. His approach demonstrated that the validity of thought experiments is eventually determined by actual observation and physical experiments, which have repeatedly confirmed the predictions of Einstein's theory of relativity over time.
