Lie great number of lies, depending on how the political wind blows." The question of whether lies can reliably be detected through nonverbal means is a subject of some controversy. Polygraph "lie detector" machines measure the physiological stress a subject endures in a number of measures while he/she gives statements or answers questions. Spikes in stress are purported to indicate lying. The accuracy of this method is widely disputed, and in several well-known cases it was proven to have been deceived. Nonetheless, it remains in use in many areas, primarily as a method for eliciting confessions or employment screening. Polygraph results
Collider Detector at Fermilab p > 1.4 GeV/c. These drift chambers work in the same way as the COT. They are filled with gas and wire. The charged muons ionize the gas and the signal is carried to readout by the wires. Understanding the different components of the detector is important because the detector determines what data will look like and what signal one can expect to see for each of your particles. It is important to remember that a detector is basically a set of obstacles used to force particles to interact, allowing physicists to “see” the presence of a certain particle. If
