Geometry Dash

Geometry Dash is a 2013 mobile game and Steam game developed by Sweden-based developer Robert Topala, and published by his own company RobTop Games. It is a rhythm-based running game which currently has 20 levels. Each level features unique background music. Although the player is not required to complete a level to advance to the next, they increase in difficulty for the most part. Other features of the game that exist in the latest versions are a level editor, map packs, user-created levels, secret coins, user coins, a secret vault and a great variety of icons and game modes.

Gameplay

Geometry Dash uses a simple tapping/clicking system to control different vehicles that react when a player presses anywhere on the touchscreen (space/up key(s) or mouse if playing on the Steam version) and can be held down to constantly interact (on some vehicles). Users cannot control the speed at which the icon is moving, unless it interacts with a speed changing portal. The timing and rhythm are key parts of the game.

UCI race classifications

The Union Cycliste Internationale (UCI), the world's governing body in the sport of bicycle racing, classifies races according to a rating scale.

The rating is represented by a code made of two or three parts and indicates both the type or style of race (the first part), and its importance or difficulty (the second and third parts). The first part can be an integer or an abbreviation, and the second part, when present, are usually integers. Both parts are separated by a period or decimal point (.).

A higher rated race will result in the successful riders receiving more world ranking points.

Road racing

The first part of the codes to rate a road race is '1' for a one-day race, and '2' for a multi-day (stage) race. They are separated from the second part of the classification, the ranking, by a decimal point. 'HC' (beyond categorization, from French hors catégorie) is the highest ranking category, followed by '1' and then '2'. For example, a race rated 1.1 equates to a one-day, category 1 race.

EMD Dash 2

The EMD Dash 2 is a line of diesel-electric locomotives introduced by General Motors' Electro-Motive Division (EMD) on January 1, 1972. Designations of these models were those of the former models with "-2" added (e.g., the SD40 was replaced by the SD40-2). They retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a number of improvements to the locomotives' internal systems, specifically the electrical systems. These were intended to improve availability, efficiency, and ease of maintenance.

One major improvement was a modularized electrical control cabinet, allowing maintenance by unit replacement and the use of common parts. These concepts were first tested on the DDA40X.

Changes

Minor externally visible changes common across the whole line include the following:

Geometry

Geometry (from the Ancient Greek: γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths, areas, and volumes, with elements of formal mathematical science emerging in the West as early as Thales (6th century BC). By the 3rd century BC, geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow.Archimedes developed ingenious techniques for calculating areas and volumes, in many ways anticipating modern integral calculus. The field of astronomy, especially as it relates to mapping the positions of stars and planets on the celestial sphere and describing the relationship between movements of celestial bodies, served as an important source of geometric problems during the next one and a half millennia. In the classical world, both geometry and astronomy were considered to be part of the Quadrivium, a subset of the seven liberal arts considered essential for a free citizen to master.

Dash

A dash is a punctuation mark that is similar to a hyphen or minus sign, but differs from both of these symbols primarily in length and function. The most common versions of the dash are the en dash (–) and the em dash (—), named for the length of a typeface's lower-case n and upper-case M respectively.

Usage varies both within English and in other languages, but the usual convention in printed English text is:
