3 Enlightenment, science and empiricism

The Enlightenment's dedication to reason and knowledge did not come out of the blue. After all, scholars had for centuries been adding to humanity's stock of knowledge. The new emphasis, however, was on empirical knowledge: that is, knowledge or opinion grounded in experience. This experience might include scientific experiments or firsthand observation or experience of people, behaviour, politics, society or anything else touching the natural and the human. For any proposition to be a

2.3 Trojans

The term Trojan comes from the Greek legend about the fall of the city of Troy. The story goes that, during the seige of the city by the Greeks, a huge, hollow wooden horse was left in front of the gates. The inhabitants thought that it was a peace offering from the Greek army and dragged it into the city. Unknown to them, it was being used to conceal Greek soldiers, who were thus able to use this Trojan horse to enter the city and open the gates for the rest of their army.

Introduction

This unit looks at three different uses of genetic testing: pre-natal diagnosis, childhood testing and adult testing. Such tests provide genetic information in the form of a predictive diagnosis, and as such are described as predictive tests. Pre-natal diagnosis uses techniques such as amniocentesis to test fetuses in the womb. For example, it is commonly offered to women over 35 to test for Down's syndrome. Childhood testing involves testing children for genetic diseases that may not

4.5.2 Noble gas configurations under stress

It is remarkable how many molecules and ions of the typical elements can be represented by Lewis structures in which each atom has a noble gas shell structure. Nevertheless, many exceptions exist. According to the periodic trends summarised in Section 2, the highest fluorides of boron and phosphorus are BF3 and PF5. How

6 Direct heating using geothermal energy

In the same way that waste heat from conventional power stations can be used for direct heating of buildings, and in industrial production and horticulture, low-grade geothermal energy has considerable potential. Many existing developments, such as those in Iceland, use spent fluids from geothermal electricity generation. Areas of natural hot springs are an obvious target, but it is also relatively simple to exploit normal heat flow using either natural groundwater or a variety of heat-exchan

1.1 Introduction

The fundamental principles of signalling can be illustrated by a simple example in the yeast S. cerevisiae (Figure 1). In order to sexually reproduce, a yeast cell needs to be able to make physical contact with another yeast cell. First, it has to ‘call’ to yeast cells of the opposite mating type. It does this by secreting a ‘mating factor’

Hitlers Death - The Final Report - Part 2 of 5
The corpses were taken to Berlin. Autopsies were done. There were some inconsistencies in the autopsies to Hitler's body. The body was so damaged (burnt before buried) that what the the only way to confirm his death was by examining his teeth. There is some account on Stalin's disbelief that Hitler was dead. There is some retelling of some witnesses of the last days in Hitler's bunker. The remains of the body is said to have been taken to different places.

"1500 Doomed": People's Press Reports on the Gauley Bridge Disaster
The deadly lung disease silicosis is caused when miners, sandblasters, and foundry and tunnel workers inhale fine particles of silica dust--a mineral found in sand, quartz, and granite. In 1935, approximately 1,500 workers--largely African Americans who had come north to find work--were killed by exposure to silica dust while building a tunnel in Gauley Bridge, West Virginia. Ordinarily, silicosis takes a several years to develop, but these West Virginia tunnel workers were falling ill in a matt
