Proper velocity by Hermann Minkowski's flat-space metric equation . Here a reference map frame of yardsticks and synchronized clocks define map position x and map time "t" respectively, and the "d" preceding a coordinate means infinitesimal change. A bit of manipulation allows one to show that proper velocity where as usual coordinate velocity . Thus finite "w" ensures that "v" is less than lightspeed "c". By grouping "γ" with v in the expression for relativistic momentum p, proper velocity also extends the Newtonian form of momentum as mass times velocity to high speeds without a need for relativistic mass. The proper velocity
Velocity (newspaper) in Louisville, and gay life. Regular weekly features included "The Bar Hopper", in which a local tavern was profiled; "The Party Crasher", a photo-story from the weekend's parties; and "What I'm Into", a mini-profile of a local person. "Velocity" was discontinued during a round of budget cuts by Gannett. Velocity (newspaper) Velocity was a free, weekly newspaper published between December 3, 2003 and June 15, 2011, by "The Courier-Journal" of Louisville, Kentucky. The full-color tabloid was distributed at 1,800 locations in a 13-county area in Kentucky and Southern Indiana. "Velocity" was widely seen as an attempt by the "Courier-Journal" and
