Animals at the extremes: polar biology

...liquid water as well as cracks caused by weather and currents. Hence sea-ice appears opaque rather than transparent like freshwater ice. The pores harbour a variety of single-celled algae, bacteria and other microbes that form the basis of surprisingly productive food chains. Most of those living on or near the surface are photosynthetic, and during the summer, such...

Sound for music technology: An introduction

...solid or liquid objects in their vicinity. In general, if there is no sound or other disturbance to the pressure of a sample of air, the molecules are evenly (though randomly) distributed throughout the sample. The pressure of air (or any gas) is related to how closely packed its molecules are (Figure 3). If the molecules are widely dispersed, the pressure is lower than...

...solid-state drive for secondary memory. These drives use integrated circuits much like main memory and have the advantages of containing no moving parts and being much faster to access. However, they are a more expensive form of secondary memory, so some computers now have both solid-state drives and hard disks. The smaller solid-state drive is often used to contain...

...liquids) can be studied on the ISS where their structures are controlled by ‘quantum forces’ in a microgravity environment. These effects were predicted over 30 years ago and were first observed in 2008. You first need to appreciate the change in size scales and the best way to do this is by using a logarithmic scale. Remember in Week 2 you were introduced to a...
