Theory and research have a complex interrelationship. Theories generate hypotheses that can be proven or disproved by research, the results of which may cause the theory to be strengthened. The results of research may also call a theory into question, causing it to be rejected or revised.Know More
A theory is a widely accepted principle or explanation of nature. In science, a theory is the most reliable form of knowledge. It is expressed in a logical form and based on substantial evidence. Examples of scientific theory include the heliocentric theory that the Earth rotates around the sun, the cell theory that living things are composed of cells and the theory of plate tectonics that explains the movement of solid plates comprising the surface of the Earth. Research is creative work used to increase the knowledge available to humankind. Both theory and research are part of the scientific method, a process by which knowledge is acquired, corrected and integrated into the totality of verifiable knowledge.
A theory is not the same as a hypothesis, which is a testable prediction made before carrying out research. A hypothesis is an idea that has yet to be tested, whereas a theory has already been tested, supported and generally accepted. A hypothesis is focused on a specific set of circumstances, while a theory is a more general explanation or observation.Learn more about Homework Help
Robert Boyle (1627-1691) is known as “The Father of Chemistry” for his discovery that atoms must exist based on the relationship between pressure and volume of gas. His theorem called Boyle’s Law reasons that because a fixed mass of gas can be compressed, gas must be made of particles, or atoms, because there is space between them. Boyle’s discoveries helped bring chemistry into the modern age.Full Answer >
Paper towels are composed of cellulose fibers, which are created from tiny sugar molecules that are the key factor to making the paper towel absorbent. The sugar molecules in the paper towel do not make it edible. Humans lack the enzymes required to break down these sugar molecules, therefore, there is no nutritional value to a paper towel. The loosely woven fibers used to make the paper towel also play a large part in the absorbency offered.Full Answer >
