I. Our Senses Encode the Information Our Brains Perceive * Synesthesia- The perceptual experience of one sense that is evoked by another sense * For many years scientists dismissed synesthesia as rare curiosity or outright faking * Far more common than previously believed * Brain regions for different sensory modalities cross-activate one another * Sensation- Simple stimulation of a sense organ * Perception- The organization‚ identification‚ and interpretation of a sensation

effects of electric charge were first observed as static electricity: • Coulomb’s Law • The Electric Field • Electric Field Lines • Shielding and Charging by Induction • Electric Flux and Gauss’s Law After being rubbed on a piece of fur‚ an amber rod acquires a charge and can attract small objects. Charged Objects and the Electric Force 19-1 Electric Charge Like charges repel and unlike charges attract each other. Quiz 1 All electrons have exactly the same charge; the charge on the proton

-contact of the rod with the electroscope will cause a transfer of electrons and leave a permanent charge on the electroscope -the charge on the electroscope will be identical to that on the rod Charging by Induction -the movement of electrons within a substance caused by a nearby charged object. There is no direct contact. -a charged object is used to induce a charge in a neutral object and then the object is grounded so that charge is retained -Grounding is the process of connecting a charged object

ON THE ELECTRODYNAMICS OF MOVING BODIES By A. EINSTEIN June 30‚ 1905 It is known that Maxwell’s electrodynamics—as usually understood at the present time—when applied to moving bodies‚ leads to asymmetries which do not appear to be inherent in the phenomena. Take‚ for example‚ the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet‚ whereas the customary view draws a sharp distinction

under the pressure of a fluid and transfers the force of the expanding gas to a crankshaft through a connecting rod (The American Heritage‚ 2005). Pistons typically consist of a few main features. Pistons are cylindrical. The top part of the piston that comes into contact with the expanding gas is the crown. All pistons have a wrist pin hole to contain a steel wrist pin that attaches the piston to a rod that is connected to the crankshaft. The skirt of the piston is the end opposite the crown and is

the automotive engine uses four strokes to convert chemical energy to mechanical energy through combustion of gasoline or similar hydrocarbon fuel. The heat produced is converted into mechanical work by pushing the piston down in the cylinder. A connecting rod attached to the piston transfers this energy to a rotating crankshaft Engines having from 1 to 16 cylinders in in-line‚ flat‚ horizontally opposed‚ or V-type cylinder arrangements have appeared in production vehicles‚ progressing from

People like: Al-Jazari‚ an engineer and ingenious inventor who made some groundbreaking advances in engineering. The most significant discovery converted rotary motions into linear motions‚ using the crank and connecting rod. It is essential in pumps and engines that drive every plane‚ train and automobile on the planet. Without such a device‚ industrial revolution could not have happened hundreds of years later. Ibn Al Haytham‚ another great scientist whose ideas

Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives

Title: Compound Pendulum Background: Background 1 by Syahnaz Azlin Razlan The experiment “Compound Pendulum” was conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action
