Answer:
The printing press helped to spread new scientific ideas quickly and easily.
Step-by-step explanation:
It was Johannes Gutenberg who was credited for inventing the printing press in 1439. This new invention would be widespread and allowed for many people to easily and cheaply share ideas. Before the printing press, the scholar had to either write the entire discovery by hand (or hire a scribe to do so) for any number of copies they wanted to produce. It was very time consuming before the printing press was invented.
