What is the explanation of how things work 100% of the time?

I didn't know that anything worked 100% of the time.

perfect?

You need to sharpen your questions some. They are too general.

You may be thinking of perpetual motion?

if something works 100% of the time then there would be no errors, human or equipment related

With my reliability hat on I can tell no piece of equipment will work for ever. The reliability of many things follows the bath tub curve. "In less technical terms, in the early life of a product adhering to the bathtub curve, the failure rate is high but rapidly decreasing as defective products are identified and discarded, and early sources of potential failure such as handling and installation error are surmounted. In the mid-life of a product—generally, once it reaches consumers—the failure rate is low and constant. In the late life of the product, the failure rate increases, as age and wear take their toll on the product. Many consumer products strongly reflect the bathtub curve, such as computer processors."

As an AI, I can explain how things work in a general sense, but it is important to note that there may not always be one single explanation that applies 100% of the time to everything. Many phenomena and systems are complex and can have multiple factors, variables, and exceptions that influence their behavior. However, there are scientific laws and principles that provide explanations for a wide range of phenomena and help us understand how things work most of the time.

To understand how something works, here are a few steps you can take:

1. Define what "thing" or phenomenon you are trying to understand. It's important to have a clear understanding of what you are studying or investigating.

2. Gather information: Read books, articles, research papers, or watch videos related to the topic. Make sure to consult reliable sources and experts in the field.

3. Identify relevant scientific laws and principles: In many cases, there are established theories, laws, or principles that explain certain phenomena. For example, Newton's laws of motion explain the behavior of objects in motion, or the laws of thermodynamics explain energy transfer and transformation.

4. Apply the scientific method: The scientific method involves making observations, forming hypotheses, conducting experiments, and analyzing data to draw conclusions. By following this approach, you can gather evidence and evaluate different explanations.

5. Consider multiple perspectives: Sometimes, complex phenomena require taking into account different perspectives or theories. It's important to consider alternative explanations and critically evaluate the evidence supporting them.

6. Test and corroborate: If possible, conduct experiments or gather empirical data to test your explanations. Replicating experiments and having other scientists review your work can help establish the reliability of your findings.

Remember that science is an ongoing process of inquiry and discovery. New evidence, advancements in technology, or paradigm shifts can revise or refine our understanding of how things work. So, while we strive for explanations that work most of the time, it is always important to remain open to new information and to critically evaluate our understanding.
