Adam's ribs

At Sunday School they were teaching how God created everything, including human beings.

Little Johnny, a child in the kindergarten class, seemed especially intent when they told him how Eve was created out of one of Adam's ribs.

Later in the week his mother noticed him lying as though he were ill, and said. "Johnny what is the matter?" Little Johnny responded, "I have a pain in my side. I think I'm going to have a wife."

Portland cement

In 1824, in Yorkshire, England, Joseph Aspdin, a stone mason, patented Portland cement, made by burning finely pulverized lime and clay at high temperatures in kilns (UK patent No. 5022). Thus Aspdin had made a manufactured counterpart to natural or Roman cement - a crude formulation of lime and volcanic ash used as early as 27 BC. Aspdin produced a hydraulic cement that would harden with the addition of water. He named his invention "Portland cement" not only to distinguish it from Roman cement, but also as a marketing tool: concrete made from his new cement resembled a highly prized building stone quarried on the Isle of Portland off the British coast. Like flour in a fruit cake, cement glues aggregate (sand or gravel) together to make a "rock" (concrete).
