We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture.

Summary

This quote emphasizes the importance of practical experimentation in the field of science. It suggests that relying solely on theoretical speculation can lead to unfounded and unrealistic ideas. To avoid this, scientists need direct contact with experiments to test and validate their theories, ensuring a more accurate understanding of the natural world. Without this hands-on approach, there is a risk of deviating into conjecture and creating false assumptions. The quote encourages scientists to ground their work in empirical evidence through experimentation for a more credible scientific pursuit.
