"How To Dunk A Doughnut"

I'm sure these bits of knowledge will serve me well at parties.

• Only after a.d. 1300 did the idea of putting a wheel between the front shafts (of a wheelbarrow), invented a thousand years earlier in China, make its way to the West.
  


• Microwave oven - the amount of energy absorbed by the food depends on how much moisture is present and its position in the spatially uneven microwave field in the oven.


• An MRI scanner subjects these atoms to a weak radio signal that tilts them over. The spinning atoms respond just as a tilted bicycle wheel would, by trying to recover the direction of their spins. The speed at which they can do this depends on how "sticky" the local brain environment is, which can be different in sickness and in health.


• Tilting the head at a constant rate provides a cue which tells the catcher that he or she is standing in right position. It seems that this is the cue that children learn, and which they continue to use into later life.


• Scientists who have become bored with long Greek words simply call the hydrophilic and lipophilic ends heads and tails respectively.


• The difference is that micelles carry oil-soluble materials such as grease, whereas liposomes can carry materials that are soluble in water. The membranes that encapsulated the first living cells were probably liposomes formed spontaneously from lecithins..


• ...whose star student in the use of the Langmuir trough was a young grocer's daughter called Margaret Roberts, who was then embarking on a career as a food scientist... She married a man named Denis Thatcher.


• Some microemulsions contained no droplets at all. The oil and water phases simply wound in and out of each other in a series of intricate curves, generating what came to be called a bicontinuous phase.
