  1. Applications of Diffraction and Interference of Light By: Karen Cooper

  2. Scanning Tunneling Microscopy

  3. Past • Gave scientists the ability to explore and manipulate solid surfaces on the size scale of atoms. • Helped discover fullerenes- spherical carbon molecules.

  4. Quantum Corrals . N.d. IBM Almaden Research Cente. N.p., n.d. Web. 16 Mar. 2011. <http://www.almaden.ibm.com/vis/stm/>.

  5. Present • Detects the flow of electrons • industrial and fundamental research to obtain atomic-scale images of metal surfaces

  6. Slippery. 2005. Scanning Tunneling Microscope. N.p., n.d. Web. 16 Mar. 2011. <http://www.umsl.edu/ ~fraundorfp/stm97x.html>.

  7. Future • To allow people to bring a "specimen" to a scanned probe microscope lab, put on a head-set designed for virtual reality, and stand among friends on a landscape of molecules resting on the specimen's surface. Every few seconds, the surface will ripple a bit, as the scanning probe tip passes by.

  8. Holograms

  9. Holography involves two basic steps: (1) creating a hologram and (2) illuminating the hologram to display the image.

  10. Holographic Violin. 14 Mar. 2011. Hologram Holography Technology. N.p., n.d. Web. 16 Mar. 2011. <http://www.hologramresources.com/history>.

  11. Past • originally a sci-fi concept back when Star Wars previewed such technology • electron microscopy

  12. Holographic Leia. N.d. IT-Networks. N.p., n.d. Web. 16 Mar. 2011. <http://www.it-networks.org/ 2010/11/05/holographic-communication-flickers-into-life-in-arizona/>.

  13. Present • Used in credit cards to prevent counterfeiting • Appear in advertising displays, artwork, product packaging, and jewelry • Used to detect flaws in tires, lenses, airplane wings, and other products • Used in lasers and electron microscopy

  18. Spectroscopy

  19. Began work with Sir Isaac Newton(late 1600’s)

  20. Past • Used to determine what chemical elements are in a star • Used to study radio waves

  21. Present • Reveal the speed and direction of stars • Used to learn more about a material’s composition or structure • Used to obtain images of tissues inside a body

  22. Future • detection in clinical chemistry • metabolic studies and continuous monitoring • detection of lower concentrations of biological compounds

  23. Astronomy

  24. Astronomers observe the sky with telescopes of different kinds that gather not only visible light but also invisible forms of energy, such as radio waves.

  25. Past • Used in telescopes to detect visible light and other forms of radiation emitted from celestial objects • Used to tell how dense an object (such as the Moon) is

  26. Present • Radio astronomy • Telescopes- produces “pictures” of astronomical objects • Used to reveal the speed and direction of a star

  27. Future • Improve radio astronomy • Improve modern astronomical observation • Predict the future structure of the universe
