The Code Stories has reached 50 posts!!

For our 50th post, we wanted to do something special.

So here is a special post talking about the significance of the number 50 in various fields.

Mathematics:

1. It is the smallest number which is the square of two square numbers in two distinct ways:
50 = 12 + 72 and 52 + 52
2. Further it is the sum of 3 squares (32 + 42 + 52) and the sum of 4 square numbers (62 + 32 + 22 + 12). It is called a “Harshad number”
3. It is “nontotient”.

A number n is nontotient if there is no integer that has exactly n coprimes below it.

Science:

1. It is the atomic number of tin(Sn) which is widely used for plating steel cans, used as food containers. Funnily, it is the 49th most abundant metal on earth.
2. It is the fifth “Magic number” in nuclear physics.
A “Magic number” is a number of nucleons (protons or neutrons) that are arranged in complete shells in the nucleus making atoms with a “magic number” of nucleons more stable.

Religion:

1. In Kabbalah, there are 50 Gates of Wisdom and 50 gates of Impurity.
2. The Christian feast of Pentecost takes place on the 50th day of the Easter season

Thanks for helping us reach this milestone!

We have a lot planned for the future, so stay tuned!
