Problem: The Kingdom of Yugoslavia (, , "Kingdom of South Slavia") was a state in Southeast Europe and Central Europe, that existed during the interwar period (19181939) and first half of World War II (19391943).

It was formed in 1918 by the merger of the provisional State of Slovenes, Croats and Serbs (itself formed from territories of the former Austro-Hungarian Empire) with the formerly independent Kingdom of Serbia. The Kingdom of Montenegro had united with Serbia five days previously, while the regions of Kosovo, Vojvodina and Vardar Macedonia were parts of Serbia prior to the unification.

For its first eleven years of existence, the Kingdom was officially called the Kingdom of Serbs, Croats and Slovenes, but the term "Yugoslavia" was its colloquial name from its origins. The official name of the state was changed to "Kingdom of Yugoslavia" by King Alexander I on 3 October 1929.

The state was ruled by the Serbian dynasty of Karaorevic, which previously ruled the Kingdom of Serbia under Peter I from 1903 (after the May Overthrow) onwards. Peter I became the first king of Yugoslavia until his death in 1921. He was succeeded by his son Alexander I, who had been regent for his father. He was known as "Alexander the Unifier" and he renamed the kingdom "Yugoslavia" in 1929. He was assassinated in Marseille by Vlado Chernozemski, a member of the Internal Macedonian Revolutionary Organization (IMRO), during his visit to France in 1934. The crown passed to his then-still under-aged son Peter. His cousin Paul ruled as Prince regent until 1941, when Peter II would come of age. The royal family flew to London the same year, prior to the country being invaded by the Axis powers.

Problem: Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be "like a magic carpet...You could fold it up and put it into your pocket or handbag". Then he paused: "But you'll always be limited by the size of the wheels. And so far no one has invented a folding wheel." It was a rare -- indeed unique -- occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout's Wonderful Bag, a leather case. Grout's aim: to solve the problems of carrying a bike on a train. Now doesn't that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout's day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn't do the same with a wheel fitted with a one-piece inflated tyre. So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse . Throughout, the tyre remains inflated. Will the young Fitzsimons's folding wheel make it into production? I haven't the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It's as silly a concept now as it was 100 years ago: there's plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than PS1,000 that can be knocked down so small that it can be carried on a plane -- minus wheels, of course -- as hand baggage. Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie's imagination? No. But it's progress.

Problem: Five-year-old Jocelyn Rojas spent all day playing happily with her friends outside her grandmother's apartment building. Her mom, Jaimee, kept her eye on the little girl from a window. At about 4 p.m., Jocelyn walked around the corner of the building to get her bicycle. However, half an hour later, she disappeared. Jaimee called 911. A short time later, police officers and firefighters crowded inthe area, blocking streets and searching the neighborhood. Officers handed out photos of the girl wearing thick-framed glasses. Temar Boggs, 15, a school athlete in track, was with some friends moving a couch into the apartment of his elderly neighbor when one officer approached him and asked if he'd seen Jocelyn. Unfortunately, none of them had seen her. A little bit later, Temar and his friends went to check out the situation. By 6:30 p.m., Jocelyn had been missing for more than two hours, and the search team was worried that the sun would set before she was found. Just at that moment, Temar felt an intense emotion that he was going to find her. He and his friend Chris Garcia, 13, rode alongside, simply keeping a sharp eye out as they circled around. Then Temar spotted a car circling around, as if the driver were unfamiliar with the neighborhood. Temar cycled close and made eye contact with the man behind the wheel, an older guy wearing a red-and-white striped shirt, and saw a tiny blond girl in the passenger seat. Temar instantly realized it must be the missing girl. The boys cycled after the car, but the driver kept moving, winding his way through the neighborhood. Finally, the driver had to park the car ahead of them and pushed open the passenger-side door. A girl slipped out of the car. It was Jocelyn. Temar got off his bike, and carried her to the police. The kidnapper sped away. A police report later identified the man as a 63-ycar-old sex offender. He is still _ . Neil Harkins, chief of the Manheim Police Department, says "The boys' heroics are 'something we don't normally hear about.' It is a very brave thing for young boys to do that." But when asked, Temar, now a tenth-grade student at Lucy Laney High School, says "I didn't do it for attention. I just wanted to help."
