Richard Feynman once said that nobody really understands Quantum Mechanics. Today, the same can be said about Materials Informatics. The industry can be confusing, with "apples" often compared to "oranges," leading to wasted time researching and testing the wrong solutions. Mat3ra.com (formerly known as Exabyte.io) was founded before the term "Materials Informatics" even existed, and we have experienced the industry's emergence firsthand. In fact, Mat3ra has been mentioned among the key players in the industry of Materials Informatics at least four times in 2023 alone, and yet even we are still confused about what the term means! Why? Read on to find out.
