How did we get the first straight edge?

The term straight edge was adopted from the 1981 song “Straight Edge” by the hardcore punk band Minor Threat. Straight edge emerged amid the early-1980s hardcore punk scene. Since then, a wide variety of beliefs and ideas have been associated with the movement, including vegetarianism and animal rights.

How is a straight edge made?

Granite engineer’s straight edges are first roughly cut from a large block of granite. This is done using large water cooled saws. Once the general shape has been attained, the finish and accuracy required for use as an engineer’s straight edge is achieved by grinding, scraping or lapping.

Do perfectly straight lines exist in nature?

Straight lines do not exist in nature. Some have mentioned the thread of a spider, which is technically a bunch of bumps called atoms that are arranged to approximate a straight line.

Who created the straight line?

Thales was probably the first known scientist and engineer and is known for his advanced application of geometry which requires straight lines. The Romans were also good at creating long straight lines they used a device called a gromer for creating long and very straight roads.

Why do humans like straight lines?

The reason we like straight lines is because of a fundamental property of the Universe – the shortest distance between two points is a straight line. Nature also follows this principle.

What are the drafting tools that has straight edges?

A straightedge or straight edge is a tool used for drawing straight lines, or checking their straightness. If it has equally spaced markings along its length, it is usually called a ruler. Straightedges are used in the automotive service and machining industry to check the flatness of machined mating surfaces.

Which tool is used to straight line?

A ruler or a scale is a mathematical instrument that is used to draw straight lines.

Is a circle made up of straight lines?

A circle is a plane figure contained by one line, which is called circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.

When was the straight line discovered?

You might know this relation, discovered by the 5th-century B.C. Greek mathematician Pythagoras, as a² + b² = c². The “c” is the hypotenuse, and although it represents the longest side of a right triangle, it is the shortest path between the two points on either end.

Who was the first person to create straight lines?

Died in 346 BC in Miletos, Turkey. Was somewhat of a mathematician.. Thales was probably the first known scientist and engineer and is known for his advanced application of geometry which requires straight lines. The Romans were also good at creating long straight lines they used a device called a gromer for creating long and very straight roads.

How straight were the roads in ancient Rome?

Roman roads were fairly straight, if one is judging on a fairly large area, but on a small scale, they would be far less straight than the line you could draw by simply running a pencil along the side of a tout string (but nobody was using strings that were hundreds of kilometres long).

Do a lot of things in nature have perfectly straight line edges?

Not a lot of things in nature have perfectly straight line edges. I would suggest that in nature there is nothing that ever absolutely matches a simple geometric shape; so there is nothing that ever matches an exact straight line.
