When using science to investigate physical phenomena, which of the following is NOT a characteristic of the event must exist?
measurable
falsifiable
observable
readable
The answer is readable
In the scientific investigation of physical phenomena, it is important to ensure that certain characteristics are present in the event being studied. This helps in conducting rigorous and reliable scientific research. Let's look at each of the given characteristics and determine which one is NOT necessary:
1. Measurable: For a phenomenon to be investigated scientifically, it should be measurable. This means that the event must be quantifiable in some way, allowing scientists to collect data and quantify the variables involved.
2. Falsifiable: A crucial aspect of scientific investigation is the ability to test hypotheses and claims in a way that allows for potential falsification. This means that the event should have the potential to be proven false or discredited through empirical evidence or experimentation.
3. Observable: In order to study a physical phenomenon scientifically, it must be observable. This implies that the event should be able to be detected and measured through direct or indirect means, either through human senses or with the help of specialized scientific instruments.
4. Readable: The term "readable" is not typically used in the context of scientific investigation of physical phenomena. While written documentation and records are often helpful in scientific research, they are not a necessary characteristic of the event itself. Therefore, "readable" is NOT a characteristic that must exist in the event being investigated.
To summarize, out of the given characteristics, "readable" is NOT a necessary characteristic of an event being investigated using science.
