Proton Soup said:frequency is the most fundamental. from frequency, we can derive both time and length.

f = 7HzFlexGunship said:Uhh... okay... 7Hz.
Go.
Jimmy Snyder said:f = 7Hz
t = 1 / f = 1/7 seconds
l = c / f (where c is the speed of light in a vacuum) = 4 x 10^7 meters.

FlexGunship said:Nope, L = 6 inches.

It is my daughter's favorite number. It has the following bizarre feature she discovered:
In a base 26 number system where a=0, z=25, 'car' is a perfect square whose root is bl=37.
Fundamental quantities are physical quantities that are considered to be the most basic and essential for describing and measuring the physical world. They are the building blocks of all other physical quantities and are used to define and derive all other quantities in physics.
There are seven fundamental quantities in the International System of Units (SI): length, mass, time, electric current, temperature, amount of substance, and luminous intensity. These quantities are used to measure all other physical quantities in the SI system.
Fundamental quantities are important because they provide a standardized and universal system of measurement that is used by scientists and engineers worldwide. They also allow for precise and accurate measurements, which are essential for understanding and predicting the behavior of the physical world.
Fundamental quantities are defined by specific units of measurement, such as meters for length, kilograms for mass, and seconds for time. These units are based on physical constants and are used to measure the fundamental quantities in a consistent and reproducible manner.
No, fundamental quantities are considered to be constant and unchanging. They are defined in terms of physical constants, which are believed to be universal and unchanging in nature. However, our understanding and measurement of these quantities may improve over time as technology and scientific methods advance.
