...physical phenomena under investigation. Superior results are usually difficult to achieve without years of high-level exposure to fields that comprise FEA technology (differential equations, numerical analysis, vector calculus, etc.). Expertise in such disciplines is required to both fully understand the requirements of any particular design circumstance, and to be able...

...physical sense limited. Then there are those people who think that whether they're limited or not, the resources that we need now, particularly oil, and to a lesser extent gas, are controlled by a small number of countries who can exert political pressure and will indeed throttle the consuming countries. Then there are people who believe that it's inevitable that the...

...physical activity and increasing obesity within the population of the UK can be attributed to a reduction in cycling and walking and increased car use (the number of cars has doubled in 30 years) and increased television viewing (which has also doubled since the 1960s). Activity 13 Is the relationship between decreased physical activity, increased car ownership and...

...physics, chemistry and biology experiments...This practical, hands-on course aims to help you start thinking like a scientist by carrying out experiments at home and making scientific observations. You will carry out simple experiments to extract the DNA from fruit or vegetables, observe osmosis in action and bake a potato to destruction! You’ll also investigate how...

...physical things, such as a resistance, voltage or pressure; we say they are temperature transducers. The temperature 'reading' is really a graduated indication of one of those other physical quantities. It is not very useful until the instrument has been calibrated against a defined numerical scale of temperature. Here are some effects by which temperature is sensed and...
