  • The Thin Lens Equation and Magnification

    • We can use the technique of ray tracing to illustrate how lenses form images.
    • Recall the five basic rules of ray tracing:
    • The figure shows three rays from the top of the object that can be traced using the five ray tracing rules.
    • It is best to trace rays for which there are simple ray tracing rules.
    • Ray tracing is used to locate the image formed by a lens.

  • Thin Lenses and Ray Tracing

    • Ray tracing is the technique of determining or following (tracing) the paths that light rays take.
    • For rays passing through matter, the law of refraction is used to trace the paths.
    • While ray tracing for complicated lenses, such as those found in sophisticated cameras, may require computer techniques, there is a set of simple rules for tracing rays through thin lenses.
    • The rules for ray tracing for thin lenses are based on the illustrations included in this section:
    • Describe properties of a thin lens and the purpose of ray tracing

    • Aboriginal Australian art can be traced back at least 30,000 years and is one of the longest continuously practiced artistic traditions in the world.
    • Aboriginal art in Australia can be traced back at least 30,000 years; the rock art of Australian Aborigines is one of the longest continuously practiced artistic traditions in the world.
    • Aboriginal art in Australia can be traced back at least 30,000 years.

  • Cationic Chain-Growth Polymerization

    • Polymerization of isobutylene (2-methylpropene) by traces of strong acids is an example of cationic polymerization.
    • Strong acids, such as HClO4 , or Lewis acids containing traces of water (as shown above) serve as initiating reagents.

  • The Fossil Record as Evidence for Evolution

    • Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.
    • However, other fossils contain traces of skin, feathers or even soft tissues.
    • These types of fossils are called trace fossils, or ichnofossils, as opposed to body fossils.
    • Footprints are examples of trace fossils, which contribute to the fossil record.

  • Introduction to Memory Storage

    • The multi-trace distributed memory model suggests that the memories being encoded are converted to vectors (lists of values), with each value or "feature" in the vector representing a different attribute of the item to be encoded.
    • These vectors are called memory traces.
    • The memory matrix is constantly growing, with new traces being added in.
    • The multi-trace model has two key limitations: the notion of an ever-growing matrix within human memory sounds implausible, and the idea of computational searches for specific memories among millions of traces that would be present within the memory matrix sounds far beyond the scope of the human-recalling process.
    • The neural network model is the ideal model in this case, as it overcomes the limitations posed by the multi-trace model and maintains the useful features of the model as well.

  • The Origins of Language

    • Because the emergence of language is located in the early prehistory of man, the relevant developments have left no direct historical traces and no comparable processes can be observed today.
    • Alternatively early human fossils can be inspected to look for traces of physical adaptation to language use or for traces of pre-linguistic forms of symbolic behaviour.

  • Potential Energy Curves and Equipotentials

    • A potential energy curve plots potential energy as a function of position; equipotential lines trace lines of equal potential energy.
    • Equipotential lines trace lines of equal potential energy.

  • DNA Analysis Using Genetic Probes and PCR

    • Genotyping of pathogenic isolates provides valuable support during investigations of suspected outbreaks and when tracing infectious diseases.
    • It is well established that genotyping of pathogenic isolates provides valuable support for the investigation of suspected outbreaks, the detection of unsuspected transmission, the tracing of infectious agents within a community, and the identification of possible sources of infection for newly diagnosed cases.

  • Nubia and Ancient Culture

    • Nubia was a region along the Nile River, whose history can be traced from c. 2000 BCE to modern day.
    • Nubian history can be traced from c. 2000 BCE onward to 1504 AD, when Nubia was divided between Egypt and the Sennar sultanate and became Arabized.
