“Only seeing general patterns can give us knowledge. Only seeing particular examples can give us understanding.” To what extent do you agree with these assertions? In 2007‚ approximately 1.58 million scientific research papers were published‚ far more than one could possibly read in a lifetime. However‚ when I visited CERN last year‚ I was told that all of our present understanding of physics could be summarised in a few equations: General Relativity‚ describing gravity; and the Standard Model

Adeeb Matin Miller 3 3/31/14 AP Physics Mechanics Extra Credit Essay An incredible automobile safety feature that makes accidents more survivable is the crumple zone of a car. Crumple zones absorb a good amount of the kinetic energy associated with the crash‚ which does not transfer to the occupant. Parts of the crumple zone include the hood‚ bumpers‚ bumper shock absorbers‚ and quarter panels. Typically‚ crumple zones are located in the front part of the vehicle‚ in order to absorb the impact

tunneling effect to scan the surface atoms and electrons. In classical physics; electrons would not be able to pass through certain conductive materials since physical contact is required to run a current and thus a loop is created; however in quantum mechanics; physical contact is not required since the electrons take the form of quantum waves‚ moving throughout space. These quantum waves‚ when emitted from a STM tip‚ have a probability of coming in contact with underlying conductive materials; as long

Sir Isaac Newton who produced the Newtonian mechanics influenced Einstein; this led to Einstein’s development of the special theory of relativity. This theory was later expanded to gravitational fields. Einstein is best known for his mass-energy equivalence formula E = mc2 (1)‚ this has been dubbed
