- The factors that can change value during an experiment or between experiments, such as water temperature, are called scientific variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.

So far, we have given a number of examples of how both accepted theories and methods of theory evaluation have changed through time. These changes portray scientific mosaics as dynamic and seemingly always in flux. So, you might be wondering: is there some underlying universal mechanism that governs the changes in theories and methods that we see i...
Let’s frame the debate with two opposing conceptions, which we will call generalism and particularism: does the process of changes in theories and methods exhibit certain general patterns? Answering “yes” to this question would make one a supporter of the conception we’ve called generalism. Generalists believe that there is some sort of an underlyi...
To begin, let’s do a thought experiment based on the history of medical drug testing. Suppose that you and a group of other scientists want to determine whether a certain medicine can help people with insomnia fall asleep more easily. Let’s call the medicine you’d like to test Falazleep. What you are ultimately doing is seeing whether the theory“Fa...
As we’ve just seen, a mosaic’s method is profoundly shaped by its accepted theories, and methods will often change when new theories are accepted. But how does a scientific community accept those new theories? As with method employment, there seems to be a similarly universal pattern throughout the history of science whenever new theories are accep...
When Isaac Newton presented his laws of motion in his 1687 opus Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), his obvious focus was on the dynamics of moving bodies and their influence on one another. But he realized that even objects which were not noticeably interacting with one another were also par...
The fourth and final law of scientific change describes the scientific mosaic at any moment of time and is known as the law of compatibility. The law of compatibility states that at any moment of time, the elements of the scientific mosaic are compatible with each other: If two or more elements can exist in the same mosaic, we say that they are com...
We have now introduced you to all four laws of scientific change. But we didn’t introduce you to them in numerical order! The typical ordering of the laws is this: Scientific inertia was given the honour of being the first law, as something of an homage to Newton’s laws of motion (as explained above). The law of compatibility has been called the ze...
We’ve talked about how theories are accepted, but can we be more explicit about how they are rejected? If we look at the first and zeroth laws together we can derive the theory rejection theorem. By the first law, an accepted theory will remain accepted until it is replaced by other theories. By the zeroth law, the elements of the scientific mosaic...
Can there be a general theory of scientific change? To begin answering the question we first made a distinction between general and particular questions, and between general and particular theories. We went on to clarify that generalists answer “yes” to this question, and that particularists answer “no.” Afterwards we introduced four arguments used...
Student scientists will learn about what science is and how it works, and how science graduates are able to change society for the better (Section 1.2). Section 1.3 warns the student scientist about pseudoscience, and how it differs from ‘real’ science – what you are here to learn.
A variable is a quantity whose value can change. A constant is an unchanging quantity. Commonly used constants include: Some quantities can have different values (so they are variables), but within a particular experiment we do not expect their value to change.
