What does 'unification' mean in science?

• A. When two seemingly different phenomena can be explained by the same fundamental principle
• B. When two theories are discarded
• C. When you combine data from two experiments
• D. When you unify electricity and magnetism into one device

Answer: (A)

Unification in science means finding a single principle or framework that can explain several phenomena that seemed different at first. This is why the idea that two seemingly different phenomena can be explained by the same fundamental principle is the right description. A classic example is how electricity and magnetism were shown to be aspects of one theory—electromagnetism—where changing electric fields and magnetic fields influence each other. Another familiar example is gravity: the same force explains both why an apple falls to the ground and why planets orbit the Sun. So the statement that two different phenomena can be explained by the same underlying principle captures what unification is about. It’s not about discarding theories, merging data, or creating a device; it’s about a single principle tying together multiple observations.
