    Constant
In summary, a constant is a fixed value used in scientific experiments and calculations. Remembering the name of a constant is important for accurate communication and replication of experiments. Common constants used in science include the speed of light, Planck's constant, Avogadro's number, and the gravitational constant. Scientists determine the value of a constant through experimentation and may use equations and models. While a constant is typically considered to be unchanging, there are cases where it may change, such as in the case of a variable constant.

Hey folks I'm trying to remember the name of this constant my lecturer mentioned.

Here's the scenario.

Take the doubling map.

f: [0,1] -> [0,1]

f(x) = 2x if x <= 1/2

2x - 1 if 1/2 < x <= 1.

Now start with an initial condition, x[0] = 1/p where p is a prime number.

What is the probability that the orbit starting with this point is of period p-1?

The answer is roughly 0.38... but I forget what this constant is called.

I believe that would be Artin's Constant.

Great thanks for that!
 

FAQ: Trying to remember the name of a constant

What is a constant?

A constant is a fixed value that does not change during a scientific experiment or calculation. It is usually represented by a symbol or letter and is used to represent a measurable quantity.

Why is it important to remember the name of a constant?

Remembering the name of a constant is important because it helps scientists accurately communicate their findings and replicate their experiments. It also allows for proper citation and reference in scientific literature.

What are some common constants used in science?

Some common constants used in science include the speed of light (c), Planck's constant (h), Avogadro's number (NA), and the gravitational constant (G).

How do scientists determine the value of a constant?

Scientists determine the value of a constant through careful experimentation and observation. They may also use mathematical equations and models to calculate the value of a constant based on other known variables.

Can a constant ever change?

In most cases, a constant is considered to be a fixed value that does not change. However, there are certain circumstances in which a constant may change, such as in the case of a variable constant, where its value is dependent on other factors.
