EM 31 & 34 Background Electromagnetic surveys operate by projecting a simple magnetic field into the subsurface. This initial field forms eddy currents within metallic or conductive objects present below ground, which then produce a secondary magnetic field that can be detected by a receiver. The actual physical property measured is conductivity (the ability of a material to carry electrical currents). Highly conductive materials, such as metals, produce a strong secondary field thus giving a high

Everything is relative or objective Nothing is really as it seems to us and all things are subjective to the observer. Everything is relative to each person from the viewpoint. Comparative readings, of two almost unimaginably accurate precision atomic clocks located on fast moving spacecraft and airplanes and on earth, have detected this strange skewing of time and proved Einstein's theory of relativity to be fact. Stop all the clocks in the universe and movement will continue unaffected

Determining Density Purpose: To determine density using measurements of mass and volume. Hypothesis: I think that from least dense to most dense it will be water, syrup, ketchup and then sand. The reason I think this is because in all of our viscosity experiments water was the least viscous and when we did the ketchup experiments it was thick, but not thick as molasses. Finally, I think sand would be the densest because it is a solid. I am not exactly sure how to determine the density of an

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. Archimedes of Syracuse[1] formulated this principle, which bears his name. Explanation: The weight of the displaced fluid is directly proportional to the volume of the displaced fluid. Thus, among objects with equal masses,

finding ways to make existing technology smaller or more efficient. This is especially apparent in electronics, where a constant push is made to make devices smaller, lighter, and more powerful. Acoustic charge transport (ACT) is a relatively new concept and technique which has applications in both electronics and optoelectronics, which uses light instead of electricity. Not only does ACT have applications in these areas, it has distinct advantages by being smaller and more efficient than currently

In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. After sufficient heating a gas dissociates its molecular bonds, rendering it into constituent atoms. However, further heating may also lead to ionization (a loss or gain of electrons) of the molecules or atoms of the gas, thus turning it into a plasma, containing charged particles: positive ions and negative electrons.[1] The presence of a non-negligible number of charge

Senior seminar November 19, 2009 Dynamics of glass forming liquids and polymer under hydrostatic pressure By: Riccardo Casalini Last seminar Dr Riccardo Casalini talked about glass formation under pressure. His research is focused on the concept of dielectric spectroscopy. Dielectric Spectroscopy, the measurement separates molecular process on the basis of response time, providing a unique relaxation frequency along with a signature variation with frequency. If an electric field is applied
