Science, Social Science, & Life Science Science is based on empirical verification and faith in the law of uniformity (what happened in the past will happen in the future.). Science deals with Invariant Data and 5 variables. Due to the consideration of infinity, which, by definition, never arrives, social science, which deals with around 50 variables, must be based on mathematical rigor. When the final variable is Variant Data, it is calculated from a deterministic system and is not empirically verifiable. Life or computer science, such as DNA and computer software, dealing with around 500 variables, must be based on logic due to unlimited complexity and the involvement of infinity. DNA itself is Big Data, and its effect is not subjected to empirical verification.
