Quantum Transport: Atom to Transistor
The development of "nanotechnology" has made it possible to engineer materials and devices on a length scale as small as several nanometers (atomic distances are ~ 0.1 nm). The properties of such "nanostructures" cannot be described in terms of macroscopic parameters like mobility and diffusion coefficient and a microscopic or atomistic viewpoint is called for. The purpose of this course is to convey the conceptual framework that underlies this microscopic theory of matter which developed in cou
Rwanda: You Go, Girls!
The PBS WIDE ANGLE documentary series analyzes a number of significant and current global issues. In 'Ladies First' (2004), WIDE ANGLE delivers a riveting report on the political and socio-economic success of the Rwandan women after the genocide of 1994 that divided the country's major ethnic groups, the Tutsi and the Hutu. The purpose of this lesson is to use 'Ladies First' to show not only that women working together can and did create a dialogue and a basis for trust among ethnic groups, but
Middle School Portal: Math and Science Pathways (MSP2)
This activity challenges students to estimate the total number of fish in a pond, given the numbers of fish initially tagged and released, the tagged fish recaptured, and the total number of recaptured fish. The activity, part of the Figure This! collection of 80 math challenges emphasizing math in the real world, introduces the capture-recapture method as a statistical tool used by fish and wildlife experts to estimate the size of populations. The solution hint suggests that students determine
This item addresses concepts such as: entropy, free energy, first law of thermodynamics, basic reaction kinetics.
Biochemical processes, thermodynamics, and kinetics are used in the application of engineering principles to analyze, design, and develop processes using biocatalysts. Processes covered in the course include those that are involved in the formation of desirable compounds and products or in the transformation, or destruction of unwanted or toxic substances.
STP Eclipse Workspace
The STP Eclipse Workspace contains a ready to use Eclipse worksapce with source code for Statistical and Thermal Physics (STP) programs by Jan Tobochnik and Harvey Gould. Unzip this workspace and open it from within Eclipse to compile and run these programs.
Gut Feelings: short cuts to better decision making
We think of intelligence as a deliberate, conscious activity guided by the laws of logic. Yet much of our mental life is unconscious, based on processes alien to logic: gut feelings, or intuitions. In his lecture Dr Gigerenzer argues that intuition is more than impulse and caprice; it has its own rationale. This can be described by fast and frugal heuristics, which exploit evolved abilities in our brain. Heuristics ignore information and try to focus on the few important reasons. He shows that b
Computer Science 273A: Machine Learning
The goal of this class is to familiarize you with various state-of-the-art machine learning techniques for classification, regression, clustering and dimensionality reduction. Besides this, an important aspect this class is to provide a modern statistical view of machine learning.
This applet from Statistical Java allows the user to generate bivariate data for analysis with simple linear regression. The page describes the equations used to generate the data and estimate the regression lines.
The applets in this section of Statistical Java allow you to see how levels of confidence are achieved through repeated sampling. The confidence intervals are related to the probability of successes in a Binomial experiment.
This page of Statistical Java describes 11 different probability distributions including the Binomial, Poisson, Negative Binomial, Geometric, T, Chi-squared, Gamma, Weibull, Log-Normal, Beta, and F. Each distribution has its own applet.
Star Library: An Unusual Episode
Dawson (1995) presented a data set giving a population at risk and fatalities for an “unusual episode” (the sinking of the ocean liner Titanic) and discussed the use of the data set in a first statistics course as an elementary exercise in statistical thinking, the goal being to deduce the origin of the data. Simonoff (1997) discussed the use of this data set in a second statistics course to illustrate logistic regression. Moore (2000) used an abbreviated form of the data set in a chapter ex
Attendance and students' school experiences
This report was commissioned by the National Educational Welfare Board (NEWB) in Ireland. It is an exploratory study which draws together literature and findings related to characteristics of school attendance by pupils in Irish primary and post-primary schools. It uses a number of data sources, particularly re-working data collected by the Economic and Social Research Institute (ESRI) and the NEWB. In particular, it highlights issues relating to poor attendance, discussing definitions of terms
Welcome to the Family Business
Family businesses have to align their values and expectations with the external hires they bring in to help manage their companies. Incoming executives should also have the freedom to run with their own ideas.
This module will introduce students to demographic and statistical language and terms and encourage critical thinking and extrapolation skills.
Competition Within and Between Species of Parasitoid Wasps
Although competition plays a significant role in communities, it is sometimes difficult to demonstrate the complexity of competitive interactions to an introductory class. This exercise investigates the effects of competition on reproduction within and between two species. Students design an experiment by placing females on a host, alone, or with conspecific or interspecific competitors. In a subsequent lab, students gather data on the number of offspring produced by females under each condition
Community Ordination Utilizing Winter Stoneflies
This exercise in community ecology can be carried out in mid-winter and introduces participants to useful taxonomic and statistical procedures.

1 Your worries and concerns with charts, graphs and tables
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows y
