Document Summary

A body of facts and principles about the physical world. Compare your data to the hypothesis/prediction and draw a conclusion. Principles of many fields are used to see if they are consistent with a. Possibly the genetic substance by avery, macleod and. Crick and watson hypothesized that dna had a helical structure. From earlier work on tobacco mosaic virus, watson was aware of the significance of the possibility of a helix, so he predicted this shape and if this were true then an x-ray would show it. Rosalind franklin in another lab took an x-ray diffraction photo of. Unknown to her, a colleague showed watson the picture and he recognized it had a helical structure. Applying a set of general logic rules to a particular problem. Generalizing on the basis of some observations. When all attempts to falsify it have failed, it is critical to repeat experiments! When its accepted by the scientific community as true, beyond all reasonable.
