Basic and Applied Science

Basic and Applied ScienceScience is divided into two main areas: basic science and applied science. Basic science focuses on understanding the natural world and discovering new knowledge. Scientists study how things work, even if there is no immediate practical use for the information. Applied science takes discoveries from basic science and uses them to develop solutions to real-world problems. This includes advancements in medicine, engineering, and technology. Both types of science work...

The Scope of Physics01:17

The Scope of Physics

Physics is concerned with the interactions of energy, matter, space, and time, in order to discover the underlying mechanisms that underpin all phenomena. The word "physics" comes from the Greek word "phúsis", which means nature. Physics seeks to comprehend the natural world around us at its most fundamental level. It emphasizes the use of quantitative laws to do this, which could be valuable in other fields that want to push the performance boundaries of present...

The Scientific Method02:40

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Psychology as a Science01:13

Psychology as a Science

Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.
The scientific method in psychology involves six critical steps: making observations, formulating hypotheses, conducting tests, analyzing...

Scientific Inquiry and Method01:21

Scientific Inquiry and Method

Scientific Inquiry and MethodScientific inquiry is how we ask questions and find answers about the world around us. Scientists use the scientific method to test ideas and learn from evidence. This process helps them study everything from tiny germs to massive planets.The scientific method follows these key steps:Observation – Noticing something interesting in the worldQuestion – Asking a question about the observationHypothesis – Making a prediction or an educated guessExperiment –...

Scientific Theories

Scientific TheoriesA scientific theory explains natural events using facts, experiments, and observations. Scientific theories are not just guesses but well-tested explanations supported by strong evidence. Two well-known theories in the life sciences are cell theory, which states that all living things are made up of cells, and the theory of evolution, which explains how species change over time. Scientific theories continue to evolve as new discoveries emerge, helping us better understand the...
