CHEM 101-01 Notes Aug 29 th Envisioning Chemistry in our lives: Chemical Imaging techniques in Medical Diagnostics: Picture of Health (examples of chemistry) E.g. X-Ray, first one was late 1890- by Wilhelm Roentgen of his wife’s hand. Alzheimer’s Disease PET-SCAN (Positron-Emission Topography), positive electrons MRI (Magnetic Resonance Imaging): Development: Nuclear Magnetic Resonance--- Felix Bloch (1946), developed for use in 1950-1970 NMR For use in MA (molecular analysis)--- NMR to MRI in 1971 for medical use. 1986-present: wide-spread use or MRI. MRI is the name for the process NMR in medicine. Prediction from chemistry lab: spectroscopy experiment Chemical Imaging of Biological (Life) Systems Biological structures “marked” with fluorescent proteins--- proteins attach to others of same type and marked with color to create a color map. 3D imaging with X-Ray topography gives info about individual structures in biological processes. Biological Surfaces (beaches and grains of sand far away and close up image) The surface of a protein crystal thought to play a role in multiple sclerosis created with atomic force microscopy (AFM) Advanced Materials: For Better Living Includes special paints, Teflon, plastics etc. The Milk We Enjoy Is made possible by a chemical process called pasteurization developed by Luis Pasture Carbon Monoxide or Syanide--- chemicals that bind with Hemoglobin that bonds stronger than Oxygen in the lungs and therefore deprives oxygen

Chapter I, What is Science? Overview: Objects and properties Measurement systems Standard metric units and prefixes The nature of science The Scientific Method Explanations and inverstigations Models and theories Laws and Principles, Science non-science and pseudoscience Experimentation Application and limitations of science Observation, Hypothesis, Experimentation, Observatoin, Experimentation… theorize. What is Science? Science is a logical acquisition of knowledge of natural events through observation and experimentation and the body of knowledge obtained thereof. Note: 2 Types: Natural Philosophy and Moral Philosophy Natural Philosophy became “natural science” and Moral Philosophy became “Social Science” Scientific Method:
