Does this make sense?

In summary, the conversation discusses the use of predicate logic, specifically the formula Rabc and the example of a three-place predicate like "between." It is mentioned that Rabc would make sense if b and c are in the same location, but not if they are in different locations. The example of "between" is given to illustrate the importance of having three subjects after the formula. It is also mentioned that in general, if Rabc is true, then it can be read as a R b and c, meaning that Adam is running towards both Betty and Celsi, or that Adam is in between Betty and Celsi.

In predicate logic

Let R = Run towards

a=Adam
b=Betty
c=Celsi

Would a formula like Rabc make sense?

What would it read?

Would Rabc = Rab & Rac

if b and c are in the same location then it makes sense, but otherwise it doesnt.
an example of three place predicate is "between", x is between y and z, here you can't divide it into Bxy&Bxz cause it doesn't make sense.

b could be north of a and c is north east of a. Then a could be running towards both of them without b and c both in the same location.

So if B is between

then you could have Bxyz (i.e. a forumla with 3 subjects) which translates to x is between y and z. In this case it is necessary to have three subjects after B, anything else won't make sense.

Is it true that in general if Rabc

than it can be read (a R b and c)

i.e Adam 'is running towards' Betty and Celsi.

Adam 'is in between' Betty and Celso.
 

1. Why is it important to ask "Does this make sense?" during the scientific process?

Asking "Does this make sense?" helps ensure that our ideas and hypotheses are logical and supported by evidence. It also helps us identify any flaws or gaps in our reasoning, allowing us to refine and strengthen our scientific understanding.

2. How can we determine if something makes sense in science?

In science, we determine if something makes sense by evaluating the evidence and data that supports it. We also consider whether the explanation is consistent with existing scientific principles and theories.

3. Is it common for scientists to question if something makes sense?

Yes, it is very common for scientists to question if something makes sense. In fact, this critical thinking process is an essential part of the scientific method and helps ensure the accuracy and validity of scientific findings.

4. Can something make sense in one scientific field, but not in another?

Yes, it is possible for something to make sense in one scientific field but not in another. Each field of science has its own set of principles and theories that may not always align with other fields. However, the process of questioning and evaluating if something makes sense remains the same across all fields.

5. What should I do if something does not make sense in my research?

If something does not make sense in your research, it is important to revisit your data and evidence to see if there are any errors or gaps. You can also seek feedback from other scientists or experts in your field to help identify any potential flaws in your reasoning. It is also important to continue researching and gathering evidence to support your findings.
