Final answer:
Bridgman wrote this list in his journal to document his scientific experiments and their outcomes.
Step-by-step explanation:
In his journal, Bridgman created a list to record every experiment of his scientific career, including their original aim, the methods used for their development, and their final success or failure. The list served as both a historical account and a symbolic representation of Bridgman's ambitious and imaginative yet practical and laborious life. It reflected his constant aspiration towards greatness, but also highlighted the shortcomings and setbacks he encountered in his pursuit of perfection.
