Question: In 2004, NIST researchers presented evidence that an isotropic non-crystalline metallic phase (dubbed "q-glass") could be grown from the melt. This phase is the first phase, or "primary phase," to form in the Al-Fe-Si system during rapid cooling. Interestingly, experimental evidence indicates that this phase forms by a first-order transition. Transmission electron microscopy (TEM) images show that the q-glass nucleates from the melt as discrete particles, which grow spherically with a uniform growth rate in all directions. The diffraction pattern shows it to be an isotropic glassy phase. Yet there is a nucleation barrier, which implies an interfacial discontinuity (or internal surface) between the glass and the melt.
Is there an answer to this question: What is diffraction?

Answer: unanswerable


Question: Though Decca would continue to keep picture budgets lean, it was favored by changing circumstances in the film business, as other studios let their contract actors go in the wake of the 1948 U.S. vs. Paramount Pictures, et al. decision. Leading actors were increasingly free to work where and when they chose, and in 1950 MCA agent Lew Wasserman made a deal with Universal for his client James Stewart that would change the rules of the business. Wasserman's deal gave Stewart a share in the profits of three pictures in lieu of a large salary. When one of those films, Winchester '73, proved to be a hit, the arrangement would become the rule for many future productions at Universal, and eventually at other studios as well.

Question: While asthma is a well recognized condition, there is not one universal agreed upon definition. It is defined by the Global Initiative for Asthma as "a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning. These episodes are usually associated with widespread but variable airflow obstruction within the lung that is often reversible either spontaneously or with treatment".
Is there an answer to this question: What does cellular obstruction cause?

Answer: unanswerable


Question: Harriet Harman became the Leader of the Opposition and acting Leader of the Labour Party following the resignation of Gordon Brown on 11 May 2010, pending a leadership election subsequently won by Ed Miliband. Miliband emphasised "responsible capitalism" and greater state intervention to change the balance of the UK economy away from financial services. Tackling vested interests and opening up closed circles in British society were also themes he returned to a number of times. Miliband also argued for greater regulation on banks and the energy companies.
Is there an answer to this question: Who won power after Ed Miliband?
