A factory foreman was suspected of having murdered, for pay, the rival of a local union leader. After the police arrested the foreman at his home and he was taken to the police station, the officers who remained at the house asked the foreman's aunt, who was visiting him for the week, if she knew where any firearms could be found in the house. She went into the bedroom and returned with a pistol. Ballistics experts established that the pistol had been used to murder the victim, and the foreman's fingerprints were all over the pistol. At a subsequent grand jury proceeding, the district attorney introduced the pistol and the related ballistics and fingerprint evidence, and the grand jury indicted the foreman. If the foreman seeks to quash the indictment, will he prevail?

How does an observation about an object differ from an inference about that object

Energy transformations that involve one transformation from one type of energy to another are called transformations.
