Applying Psychological Theories to Modern Society Add a quote in the beginning. To this day many different characteristics of human behaviour are yet to be discovered. Psychologists must study why humans act the way they act? Could it be that all are humans are inherently evil? Why do humans not always make the right decision?

light by an analyte (the substance to be analyzed) at a certain wavelength to determine the analyte concentration. Useful wavelengths for spectrophotometry range from 185 to 3‚000 nm. Spectroscopy is one of the most powerful analytical techniques in modern science. Spectroscopy works by correlating the concentration of a species in solution to the amount of light it absorbs. It included the observations of absorption or emission of electromagnetic radiation resulting from transitions of atoms or molecules

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few. Molecular geometry is associated with the specific orientation of bonding atoms. A careful analysis of electron distributions in orbitals will usually

The device will make waiting hours for a phone to charge a thing of the past and the gizmo packs more energy into a smaller space than traditional phone batteries and holds the charge for longer. Eesha Khare made the breakthrough by creating small super capacitor that can fit inside a cell phone battery and enable ultra-fast electricity transfer and storage‚ delivering a full charge in 20-30 seconds instead of several hours. Communication has evolved massively in the recent
