Grammar Rock-Prepositions
This is a colorful School House Rock video on prepositions. The prepositions are used in phrases and illustrated accordingly. Prepositions never stand alone and give specific information. Some of the phrases are over the rainbow, with a friend, over the meadow, through the tree, etc. This is a fun teaching resource to introduce and/or reinforce prepositions in the classroom and/or at home.

21A.355J The Anthropology of Biology (MIT)
If the twentieth century was the century of physics, the twenty-first promises to be the century of biology. This subject examines the cultural, political, and economic dimensions of biology in the age of genomics, biotechnological enterprise, biodiversity conservation, pharmaceutical bioprospecting, and synthetic biology. Although we examine such social concerns as bioterrorism, genetic modification, and cloning, this is not a class in bioethics, but rather an anthropological inquiry into how t

10.2 The relationship between loudness and intensity

The loudness of an auditory stimulus is a psychological, not physical attribute of the stimulus. The physical attribute of sound that is most closely correlated with loudness is intensity. So loudness is the listener's subjective description of the intensity of the stimulus. As you know, we are not equally sensitive to sounds of all frequencies so perceived loudness of a tone in fact depends on frequency as well as intensity. Two sounds can have the same physical sound pressure levels but if

1.7.1 Carboniferous mires

During the late Carboniferous, mires developed over vast areas of the UK. Much of today's land area was an extensive, low-lying plain bordering a sea to the south (a sea that was soon to be the site of a mountain-building episode). Any mountains that existed lay hundreds of kilometres to the north. Large river systems meandered southwards across these plains.

At that time, the UK lay in tropical latitudes, almost on the Equator (see Author(s): The Open University

4.1 Introduction
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.

Introduction

Active galaxies provide a prime example of high-energy processes operating in the Universe. This unit introduces the evidence for activity from the spectra of some galaxies, and the concept of a compact active galactic nucleus as a unifying model for the observed features of several types of active galaxy. It also develops the key skill of applying arithmetic and simple algebra to solving scientific problems.

Energy resources: Wind energy
Wind energy was the fastest growing power source at the start of the 21st century, yet wind-driven mills and pumps, and nautical sails for transport, were, along with waterwheels, the first mechanical devices to power industrial production. The advantages of harnessing wind energy are obvious; it is free, clean and widely available. This free course, Energy resources: Wind energy, explores wind as a potential source of useable energy.Author(s): Creator not set
