Nonlinear Dynamics and the Lorenz Water Wheel

Undoubtedly one of the most exciting frontiers in physics today is the study of nonlinear systems, more popularly called chaos. Chaos is the key to many time-dependent processes in as varied fields as meteorology (such as weather modeling), mechanics (the three-body problem in gravitational fields), and economics (prediction of trends in the stock market)

Ensuring Survival: How Mexican Border Service and World War I was Vital for the Survival of the National Guard System

Historians and military officials often consider the National Guard as the direct descendent of the colonial militia, and the transition between the two is described as natural. However, the Guard was not the only option available to replace the militia, and many Washington officials and prominent civilians supported European style replacements based on universal military training for all able bodied men. The National Guard maintained a successful lobby and Congress redefined and solidified the new National Guard system with a series of laws during the first two decades of the twentieth century. However, detractors continued to attack the new system and the Guard needed to prove its value. Mexican border duty and service in the First World War provided the Guard with this opportunity. The training the Guard received at the border provided the Guard with the skills necessary to perform in the trenches in France, and the Guard performed better than anticipated. The border duty proved vital for the overall survival of the Guard and it allowed the Guard to provide a quickly mobilized and highly trained force to aid in the American war effort

Carbon nanotube based ion sensitive field effect transistor

Carbon nanotubes (CNTs) have been the subject of much research in the past two decades. Due to their extraordinary mechanical and electrical properties, CNTs are ideal candidates for various sensors and electronic device applications. The purpose of this research is to overcome the difficulties in separating and aligning CNTs so that they can be implemented in an ion sensitive field effect transistor (ISFET). A solution to the alignment process has been presented that involves cutting nano channels on a microelectrode chip with an Atomic Force Microscope (AFM) in order to nanomanipulate the CNTs into the nano channels. Upon successfully cutting the channels, the process of dielectrophoresis (DEP) will be used to align the CNTs into the nano channels. Preliminary work shows that the nano channels are a valid solution for bridging the gap between the electrodes, but they create an entirely new level of complexity. Cutting with an AFM can, at times, be an inconsistent process. Once the inconsistencies are overcome associated with AFM cutting, a carbon nanotube based ISFET device could be manufactured at lower cost and could operate without the need of an amplifier
