QUES: Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

QUES: The violent arena of domestic abuse litigation has grown a bit more volatile here, now that a judge has decided to hold two women in contempt of court for returning to men who had been ordered to stay away from them. "You can't have it both ways," said Judge Megan Lake Thornton of Fayette County District Court in recently fining two women $100 and $200 respectively for obtaining protective orders forbidding their partners from contacting them, then relenting and contacting the men. Ruling that the order was mutually binding, Judge Thornton also cited the men for contempt. "It drives me nuts when people just decide to do whatever they want," said Judge Thornton, who is experienced in the state's thick domestic abuse docket, which produces close to 30,000 emergency protective orders a year. Kentucky officials say there is a virtual epidemic of abusive relationships in the state. Judge Thornton's ruling has alarmed advocates for battered women, who plan to appeal it. The advocates say the finding goes beyond existing law and is unrealistic because some renewed contacts often prove unavoidable in domestic abuse cases, which involve economic and family dependency and other complications of daily living. The state office on domestic violence has pointedly agreed, warning that the ruling could cause abused women to hesitate in bringing their plight before the courts for fear of being chastised for their trouble. "The reality is it's easy to say they should never have contact," said Sherry Currens, executive director of the Kentucky Domestic Violence Association, an advocacy and legal protection group. "But we're talking about people in long-term relationships. They may have children in common. It's pretty hard to say, 'Never speak again.' People have financial difficulties. They may love the partner. It's not an easy thing." But Judge Thornton declared in court, "When these orders are entered, you don't just do whatever you damn well please and ignore them." The ruling stunned Cindra Walker, the lawyer for the two women, who is with Central Kentucky Legal Services, which represents many of the thousands of indigent women caught in abusive relationships. "For over five years, I've been in court practically every day on these abuse cases," Ms. Walker said, "and I've never before had a victim threatened with contempt."

QUES: While Nashiri was in Afghanistan, Nibras and Khamri saw their chance. They piloted the explosives-laden boat alongside the USS Cole, made friendly gestures to crew members, and detonated the bomb. Quso did not arrive at the apartment in time to film the attack. Back in Afghanistan, Bin Laden anticipated U.S. military retaliation. He ordered the evacuation of al Qaeda's Kandahar airport compound and fled- first to the desert area near Kabul, then to Khowst and Jalalabad, and eventually back to Kandahar. In Kandahar, he rotated between five to six residences, spending one night at each residence. In addition, he sent his senior advisor, Mohammed Atef, to a different part of Kandahar and his deputy, Ayman al Zawahiri, to Kabul so that all three could not be killed in one attack. There was no American strike. In February 2001, a source reported that an individual whom he identified as the big instructor (probably a reference to Bin Laden) complained frequently that the United States had not yet attacked. According to the source, Bin Laden wanted the United States to attack, and if it did not he would launch something bigger. The attack on the USS Cole galvanized al Qaeda's recruitment efforts. Following the attack, Bin Laden instructed the media committee, then headed by Khalid Sheikh Mohammed, to produce a propaganda video that included a reenactment of the attack along with images of the al Qaeda training camps and training methods; it also highlighted Muslim suffering in Palestine, Kashmir, Indonesia, and Chechnya. Al Qaeda's image was very important to Bin Laden, and the video was widely disseminated. Portions were aired on Al Jazeera, CNN, and other television outlets. It was also disseminated among many young men in Saudi Arabia and Yemen, and caused many extremists to travel to Afghanistan for training and jihad. Al Qaeda members considered the video an effective tool in their struggle for preeminence among other Islamist and jihadist movements.

QUES: Have you are burned something on the stove or in the oven? Do you know why things burn? It all has to do with temperature. Changes in matter are affected by temperature. For example, what if you place a cake in the oven and you leave it in too long? What do you think will happen? Thats right, it will probably burn. The same thing will happen if the oven setting is too high and you apply too much heat. In either case, heat has affected the rate of change in matter. Its probably obvious that when the temperature is increased a chemical change, like cooking, will occur faster. What about a physical change? Are physical changes affected by temperature? Most of us have seen steam rising off a wet road after a summer rainstorm. This happens because the road surface is very warm. The warm road and warm air temperature causes the water to evaporate quickly. The liquid water is turning into water vapor, but it is still water. The evaporation of water is a physical change. So yes, temperature affects the rate that physical change occurs.
