Why does marble stay cold




















Marble flooring is one of options that can help keep your home cooler, especially during the summer. The material is a type of rock that is derived from limestone and formed by going through high amounts of heat and pressure underground. The way marble is formed makes it denser, harder, and more durable than other commonly used materials for tiles, like porcelain, wood, and ceramic.

Even when the rest of your home feels hot and humid, your marble flooring will still remain cool. Often times, you will find that it feels colder than the other surfaces in your home. This is because the rock conducts heat in a different manner. Its high density and hardness enables heat to transfer from a warm object, like your soles. Because racing is a sport - and a high-stakes business - horses aren't bred the same way that, say, bulls or pigs are. A good bull will have his semen dispersed by artificial insemination to innumerable cows, but horses are only allowed to breed in the old-fashioned, romantic way, to avoid flooding the market.

The owners charge a hefty price for such a fling. This limited edition approach also limits the chances of a champion colt. Even a great horse like Secretariat needs a lot of chances: Of all his offspring only one, Risen Star, won numerous stakes.

Breeders are dumb, sometimes. We are told by breeding expert Paul Mostert, a professor of mathematics at the University of Kansas, that the horse community has suffered from some rather unscientific thoughts over the years, such as the idea that a little dose of these genes and a little dose of those genes will result in a genetically perfect horse.

For instance, a breeder might try to combine the genes of a great sprinter with the genes of a great long-distance horse.

The result: Alpo. Horses are retiring before they're physically mature. A lot of the old speed records were set by 5-year-olds. But now horses race at a younger age, starting at age 2, and are more likely to get hurt perhaps because physical soundness is not sufficiently emphasized in breeding. They're put out to stud while they're still adolescent.

Horses have hit their genetic peak already. Breeding has been around for centuries and they can't get faster indefinitely. At some point a species runs into a wall. Why are humans more successful at improving their times? Because humans are more adaptable than horses. They're more easily trained, more clever, able to master complex new techniques. And such great new shoes!

Be sure to dry the surface before putting the pastry on it. I know that many pastry chefs do, but I find that I end up incorporating too much flour into the dough. Instead, I lay a lightly floured canvas pastry cloth on the board and pull a floured cotton sleeve over the pin; both of these add just enough flour to prevent sticking.
