Torx (pronounced ), developed in 1967 by Camcar Textron, is the trademark for a type of screw head characterized by a 6-point star-shaped pattern. A popular generic name for the drive is "star", as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with numeral, "6", not a capital letter, "G"). Torx Plus is an improved head profile.

Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed. Torx screws are also becoming increasingly popular in construction industries.

By design, Torx head screws resist cam-out better than Phillips head or slot head screws. Whereas Phillips heads were allegedly designed to "cause" the driver to cam out, to prevent overtightening, Torx heads were designed to "prevent" cam-out. The development of better torque-limiting automatic screwdrivers for use in factories allowed this change. Rather than rely on the tool to slip out of the screw head when a desired torque level is reached (which risks damage to the driver tip, screw head, and/or workpiece), torque-limiting driver designs achieve a desired torque consistently.

Ambrose of Alexandria (before 212 c. 250) was a friend of the Christian theologian Origen. Ambrose was attracted by Origen's fame as a teacher, and visited the Catechetical School of Alexandria in 212. At first a gnostic Valentinian and Marcionist, Ambrose, through Origen's teaching, eventually rejected this theology and became Origen's constant companion, and was ordained deacon. He plied Origen with questions, and urged him to write his Commentaries () on the books of the Bible, and, as a wealthy nobleman and courtier, he provided his teacher with books for his studies and secretaries to lighten the labor of composition.

He suffered during the persecution under the Roman emperor Maximinus Thrax in 235. He was later released and died a confessor. The last mention of Ambrose in the historical record is in Origen's "Contra Celsum," which the latter wrote at the solicitation of Ambrose.

Origen often speaks of Ambrose in affectionately as a man of education with excellent literary and scholarly tastes. All of Origen's works written after 218 are dedicated to Ambrose, including his "On Martyrdom", "Contra Celsum", "Commentary on St. John's Gospel", and "On Prayer". Ambrose's letters to Origen (praised by Jerome) are lost, although part of one exists. What are the answers to this following set of questions: 1. Which religions theory did Origen believe in?

One day Mrs Black visited her family doctor, Mr Dodd. Mr Dodd was an old funny man with a beard. "What's the problem ?" the doctor asked her. "I am very worried about my son, Jake," Mrs Black said, "I can't stop him from betting. He spends all his money betting on horse races. And even worse he'll bet on everything. It doesn't matter what it is." The doctor said, "I've saved many people from gambling before. Send him to me." The next day Mrs Black sent her son to see the doctor. While they were talking , the boy was looking at the doctor's beard. Suddenly he said, "I bet you $ 50 that your beard is not a real one." "Oh, no, " the doctor said. "Can I pull your beard and find out ?" the boy said. The doctor thought this is a good way to teach him a lesson; so he said, "Ok, if my beard is real , you will have to pay me $ 50." The boy pulled it and soon found out it was real. The doctor laughed. Two days later the doctor telephoned Mrs Black, "I think I've saved your son." He told her the story.
