Graveyard Rockwalk - Part Two (#)

  „It really does look like one of those terrible stodgy puddings with raisins they used to serve for school dinners. The pebbles are made from jasper and flint - both types of quartz - and the matrix is quartz too. So the pebbles and matrix are of equal hardness. This means that when the rock splits (which it does in the local fields by frost action), a smooth face is exposed cutting right through the pebbles.“

  „So, in deciding which environment to work in to upgrade my old scientific apps, I felt stuck between two impossible choices. I wanted the power of quartz and the familiarity of C in a format I could learn. This book provides the indispensible introduction to object orientation that is a prerequisite for Cocoa and ultimately Apple's latest and greatest stuff under the hood. From there, the developer documentation and Garfinkel's or Hillegrass' books can take you the rest of the way.“

Rock Art - Essential Guide to Rocks - BBC Education

  „Crystal balls are now as popular as polished eggs. I looked into Philip's wife Nadine's favourite crystal ball and I saw quartz with cleavage planes - all crystals have planes along which they tend to split, and the planes of Nadine's ball added texture and interest and reflected the light and colours of the room. I also saw some inclusions of iron minerals. I couldn't see into the future - but I could see the past.“
