“E” Day

E-Day is an annual American holiday dedicated to the Euler number. Celebrated on February 7th. This mathematical value has no exact origin. It is a numerical sequence and is used to calculate logarithmic expressions.

History

For the first time, the number “e” was discussed about three centuries ago. The first descriptions of this mathematical phenomenon appeared in the works of John Napier, a mathematician from Scotland. He hinted and talked about a certain numerical sequence that he managed to deduce. However, the mathematician never named the value, although he claimed that with his help he managed to solve a series of logarithms.

In 1683, this magic number was deduced by Jacob Bernoulli. The common answer to the logarithmic expression was the number “e” (the author used the designation with the letter b in his works). In 1731, the numerical sequence was studied by Leonhard Euler, who gave it a name, taking the first letter from his last name.

There are still many rumors and conjectures about the Euler number, and mathematicians from all over the world do not leave attempts to discover something new based on this number.

Interesting facts

• In 2018, a funny coincidence was discovered. If we represent the record of the number (2.718281828) as 2/71 (by the first digits), then we can talk about the date October 2, 1971. It is from this day that the Day of e-mail is celebrated. And for this service, the designation e-mail is often used.
• The Euler number has a “relative” – ​​the number Pi, which is equal to 3,14 and is also an infinite value.

How to celebrate

Solve several logarithmic examples in E-Day using this numerical value. Read more interesting information online about the creation of the Euler number.

Tell about the holiday on social networks. Ask other users how often they have used the Euler number in their lives (perhaps to calculate something).
