Introduction

This course looks at the human being in the context of an individual life cycle, examining some of the processes that contribute to the formation of a new person. After a brief discussion of historical ideas about human conception, and about contraception to the present day, we look at the cells involved in the conception and development of a new individual. Gamete production (that is, production of mature cells able to unite with another in sexual reproduction) in both men and women is intro

2.2 The inventive drive

What events and ideas spurred people to come up with thousands of inventions in the last 100 years?

Ron Hickman was a do-it-yourself enthusiast who damaged a chair being used to support a piece of wood he was sawing. Instead of merely being annoyed at the accident he set about designing and building a prototype of a combined workbench and sawhorse to prevent further damage to his furniture. This became the Workmate (Author(s): The Open University

The objetive of the proyect is the hiperrealistic simulation of scenarios on standard PCs. We use the same tools that are used by the entertainment industry (3d graphics engines) to get the highest level of realism possible in 3d worlds. By now, we are exploring only the audio and visual areas. The potencial of this 3d enviorments construction tools let us to create exploration enviorments for academic and professional implementation like commerce, tourism, education, communication, etc.

7.012 Introduction to Biology (MIT)
The MIT Biology Department core courses, 7.012, 7.013, and 7.014, all cover the same core material, which includes the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organism

7.343 Neuron-glial Cell Interactions in Biology and Disease (MIT)
The main goal of this seminar will be to study the nervous system from the perspective of neuron-glia interactions. In each class, we will focus on one type of glial cell and discuss its origin, classification and function within the nervous system. Current findings concerning diseases associated with each type of glial cell will be discussed. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an inte

2.3.4 Geophysical methods — borehole logging

If a core is not recovered from a borehole, another way to assess the types of rock that it penetrates is to measure their physical properties. Mounting a string of electronic instruments behind the drill bit most conveniently does this: it allows the properties of the rock to be monitored as the borehole is drilled. An alternative is to lower instruments down the completed borehole by cable; hence the name wireline logging.

Such logging measures several physical properties of th

1 Overview

Even in images taken with the most modern equipment on a large telescope, it can be difficult to pick out the galaxies now known as 'active' from the other more normal galaxies. But if your telescope were equipped to examine the spectra of the galaxies, then the active galaxies would stand out. Normal galaxies contain stars that are generally similar to those in our own Galaxy; and spiral galaxies have additional similarities to the Milky Way in their gas and dust content. Active galax
