Particle Spin and the Stern-Gerlach Experiment
physics.mq.edu.au6.3 The Stern-Gerlach Experiment This experiment, first performed in 1922, has long been considered as the quintessential exper-iment that illustrates the fact that the electron possesses intrinsic angular momentum, i.e. spin. It is actually the case that the original experiment had nothing to do with the discovery that the
The Scientific Method - Riverside Local Schools
www.riversidelocalschools.comcompares two or more things but changes only one variable—factors that change in an ex-periment. This type of experiment is called a controlled experiment. For example, when test-ing the affects of fertilizer on plants, you would test an experimental group (with fertilizer) and a control group (without fertilizer).
The Franck-Hertz Experiment - University of Michigan
instructor.physics.lsa.umich.eduJan 30, 2006 · The Franck-Hertz Experiment The Franck-Hertz experiment, first undertaken shortly after Bohr’s theory of the atom was pre-sented, provided one of the early indications that atoms had discrete energy levels. In this ex-periment, electrons are accelerated and pass through mercury vapor, where they lose energy by
Types of Epidemiologic Studies - McGill University
www.med.mcgill.catreatments for patients who already have some disease (trial is used as a synonym for ex- periment). Epidemiologic experiments that aim to evaluate primary preventives (agents intended to prevent disease onset in the first place) are less common than clinical trials; these studies are usuallyfield trials or community intervention trials.
Correlation in Random Variables - College of Science | RIT
www.cis.rit.edu• A random variable is a function X(e) that maps the set of ex-periment outcomes to the set of numbers. • A random process is a rule that maps every outcome e of an experiment to a function X(t,e). • A random process is usually conceived of as a function of time, but there is no reason to not consider random processes that are
Ohm’s Law - Michigan State University
web.pa.msu.eduJan 24, 2013 · We will use these functions in this exper-iment. Last updated January 24, 2013 23. 2. Ohm’s Law Figure 2.2: DC power supply Figure 2.3: Digital multimeter To use the multimeter as a voltmeter, the dial selector is set to one of the positions labeled “V”. The probing cables are then connected to the
The Methodology of Organizational Diagnosis
leeds-faculty.colorado.eduEntry is like a natural ex-periment, providing consultants with an opportunity to observe how the system re-sponds when its boundaries become more permeable. As human beings themselves, consultants also experience the period of entry as a time of anxiety. In part this arises because the consultants are dealing with their
Scalable Person Re-Identification: A Benchmark
www.cv-foundation.orgIn exper-iment, we show that the proposed descriptor yields com-petitive accuracy on VIPeR, CUHK03, and Market-1501 datasets, and is scalable on the large-scale 500k dataset. 1. Introduction This paper considers the task of person re-identification. Given a probe image (query), our task is to search in a
Conversion of Thermocouple Voltage to Temperature
web.cecs.pdx.edua more precise and versatile relationship than Equation (1), consider an exper-iment where T 1 is xed, and T 2 is varied. For practical thermocouple materials the relationship between Eand T is continuous. Hence, for su ciently small change T 2 in T 2, the EMF indicated by the voltmeter will change by a corre-sponding small amount E 12. Since T ...

A sensible discussion of experiments requires both a vocabulary for talking about causation and an understanding of key concepts that underlie that vocabulary.
A logical calculus of the ideas immanent in nervous activity
home.csulb.eduAs yet ex- periment has not shown whether the refractoriness is relative or ab- solute. We will assume the latter and demonstrate that the difference is immaterial to our argument. Either variety of refractoriness can be accounted for in either of two ways. The "inhibitory synapse" may be of such a kind as to produce a substance which raSses ...
