what is a emergent property?

Answer 1

Emergent Properties

We call these properties and functions that arise from the interacting parts in a system "emergent properties". The concept of emergent properties is central to the study of systems. Any function performed by a system that is not the result of a single part in the system, but rather is the result of interacting parts in the system, is an emergent property. The light bulb's ability to generate light cannot be attributed to any of the three parts in the system on their own. Rather, it is the result of the combination of the metal cup sealing the glass bulb and passing current to the wire coil, the glass bulb maintaining a vacuum and still allowing light to radiate out, and the wire coil glowing hot enough to give off light without melting itself or the glass balloon. The light bulb's ability to give off light emerges only as a result of the interactions of the metal base, the glass envelope, and the tungsten wire filament.

Answer 2

Well, in principle, you could work out the laws of chemistry from a knowledge of physics because physics is more basic than chemistry. But as soon as the universe cooled down enough for chemical compounds to form, matter started doing things it had never done before. Similarly, as soon as we were able to make electronic circuits as complicated as computers, we had things like the Internet, viruses, language translation and computer animation that no 19th century scientist could have imagined. Emergent properties are new, interesting phenomena that arise when you reach a new level of complexity.
