Many scientists remain doubtful that true AI can ever be developed. The operation of the human mind is still little understood, and computer design may remain essentially incapable of analogously duplicating those unknown, complex processes. Various routes are being used in the effort to reach the goal of true AI. One approach is to apply the concept of parallel processing_interlinked and concurrent computer operations. Another is to create networks of experimental computer chips, called silicon neurons, that mimic data_processing functions of brain cells. Using analog technology, the transistors in these chips emulate nerve_cell membranes in order to operate at the speed of neurons.
Diagrams : A diagram can show a process, hierarchy, or other relationships. You can use AutoShapes and arrows, the flowchart shapes with connectors (in the Lines category in PowerPoint 2007; otherwise in the Connectors category), or the SmartArt feature of 2007. Charts/Graphs : Charts (also known as graphs) visually display data, especially data showing a trend. Use only the data that supports your point, not all the data in the Excel spreadsheet where you got the data. If the data is too complex, it won';t be comprehensible on a slide. What to do? Print it out and give it to the audience as a handout.
