what are the lights on the curling stone
Curling A handle is attached by a bolt running vertically through a hole in the centre of the stone. The handle allows the stone to be gripped and rotated upon release; on properly prepared ice the rotation will bend (curl) the path of the stone in the direction in which the front edge of the stone is turning, especially as the stone slows. Handles are coloured to identify each team, two popular colours in major tournaments being red and yellow. In competition, an electronic handle known as the eye on the hog may be fitted to detect hog line violations. This electronically detects whether the thrower's hand is in contact with the handle as it passes the hog line and indicates a violation by lights at the base of the handle. The eye on the hog eliminates human error and the need for hog line officials. It is mandatory in high-level national and international competition, but its cost, around US$650 each, currently puts it beyond the reach of most club curling.
All the Light We Cannot See When Germany invades France in 1940, Marie-Laure and her father flee from Paris to the coastal town of Saint-Malo[1] to take refuge with her great-uncle Etienne, a recluse suffering shell-shock from the Great War. Etienne spends all his days indoors, but reveals to Marie-Laure that along with his deceased brother Henri, the two used to broadcast lessons to children from a large radio inside the chimney, with these lessons being the ones Werner and Jutta listened to. Unbeknownst to Marie-Laure, her father has been entrusted with the Sea of Flames or one of three exact copies. The four jewels look very much alike, although three are worthless fakes. As a diversion, each of the four is given to a different protector, none of whom knows whether his blue stone is the real priceless gem or the look-alike fake. Each protector is charged to keep his jewel out of the Germans’ hands. Marie-Laure's father conceals his stone in a small wooden replica of Etienne’s house, a removable puzzle box which fits within the city model he makes of Saint-Malo. This model is placed at the foot of Marie-Laure's bed, where she spends hours learning the new town with her fingers before finally venturing out.
