Friction helps us by letting us grasp things so they won't fall. Without friction you can expect to have more car accidents, and a lot of random people falling because friction helps us walk. Also airplanes in a way use friction to fly. no slaking in class
Its the abbreviation of Program Evaluation and Review Technique / Critical Path Method. The critical path method (CPM) is a project modeling technique developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley, Jr. of Remington Rand.Kelley and Walker related their memories of the development of CPM in 1989. Kelley attributed the term "critical path" to the developers of the Program Evaluation and Review Technique which was developed at about the same time by Booz Allen Hamilton and the US Navy. The precursors of what came to be known as Critical Path were developed and put into practice by DuPont between 1940 and 1943 and contributed to the success of the Manhattan Project. CPM is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of mathematical analysis. Although the original CPM program and approach is no longer used, the term is generally applied to any approach used to analyze a project network logic diagram. PERT is a method to analyze the involved tasks in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. PERT was developed primarily to simplify the planning and scheduling of large and complex projects. It was developed for the U.S. Navy Special Projects Office in 1957 to support the U.S. Navy's Polaris nuclear submarine project. It was able to incorporate uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in projects where time, rather than cost, is the major factor. It is applied to very large-scale, one-time, complex, non-routine infrastructure and Research and Development projects. An example of this was for the 1968 Winter Olympics in Grenoble which applied PERT from 1965 until the opening of the 1968 Games. This project model was the first of its kind, a revival for scientific management, founded by Frederick Taylor (Taylorism) and later refined by Henry Ford (Fordism). DuPont's critical path method was invented at roughly the same time as PERT.
There are approximately six million fire hydrants installed in the US. The first fire hydrants, called fire plugs, were in use beginning in the 17th century.

A chief petty officer is a US Navy or Coast Guard non-commissioned officer of the grade E-7, E-8, or E-9. E-7: Chief Petty Officer E-8: Senior Chief Petty Officer E-9: Master Chief Petty Officer E-9 also can be a Command Master Chief (CMC) of the Master Chief Petty Officer of the Navy (MCPON) which is assigned to the highest ranking enlisted person in the United States Navy.
In the US Navy, the ranks of "Seaman Recruit", "Seaman Apprentice" and "Seaman" are junior to the rank of Petty Officer 3rd Class. In increasing rank are Petty Officer 2nd Class, Petty Officer First Class and Chief Petty Officer. So, yes, any of the Petty Officer ranks are higher than any of the Seaman (or Airman or Fireman) ranks.

"The paygrades of E-8 and E-9, Senior Chief and Master Chief Petty Officer, were created in 1958."
As per official US Navy documents, the answer is that no "first chief petty officer" exists. Nearly all personnel rated as petty officers first class since at least 1885 were automatically promoted to chief petty officer in 1893. These promotions occurred simultaneously, making the first chief petty officer impossible to determine.
