What is the difference between zero and zero vector in vector algebra?
Zero is a number (a scalar quantity without unit) while zero vector (or null vector) is a vector quantity having zero magnitude and arbitrary direction.
What is the level of measurements for year of birth?
It is an interval scale. It is not a ratio scale, the next higher level, because the zero is arbitrary and not unique from one calendar to another.
How does a thermometer use integers?
For temperatures, zero is an arbitrary reference point, depending on which scale is used. For Celsius, zero is assigned the the temperature at which water freezes. So temperatures which are colder than this temperature will be negative values, and temperatures warmer will be positive values. Fahrenheit uses a different reference point for zero, but similar principles apply.
What is an arbitrary integer?
An arbitrary integer is basically the same as any integer. If a math problem says: "Let n be an arbitrary integer", it means that n can be any integer. A random integer in other words.
What is 0 degree longitute?
The 0 degree longitude is the imaginary line that goes from pole to pole, passing through Greenwich in London, site of the Royal Observatory. The choice of the zero point for longitudes is arbitrary and many major cities were used. Eventually, in 1884, the Greenwich Meridian was accepted as the internationally agreed zero longitude.
