Mathematics is an important tool in Physics. That is why time is defined as the physical magnitude that continually increases in value due to becoming and is used to measure the duration of things. In the calendar the days pass increasing the length of the year. In clocks the hours and minutes pass increasing the length of the days. Physicists apply mathematics to natural phenomena to explain reality or the universe. Becoming is the continuous succession of irreversible changes that go from the past to the future through the present. The becoming can be simple or periodic. With the passage of days and years we increase our age. Age is a simple becoming while in clocks we see a periodic becoming.
