axis
part of speech
noun (an axis, axes)
meaning for a pupil
1) An axis is an imaginary straight line that something spins around, like the Earth's axis. tree →
2) In maths, an axis is one of the main lines on a graph, the x-axis going across and the y-axis going up. tree →
3) An axis of symmetry is a line that cuts a shape into two matching halves. tree →
sense in the lessons
In the mystic school: In notes 08 and 10 the axis is the upright 1 that holds the 6 and the 9 apart in 619, and the line through the middle of the 8. In the primary lessons: In science, the Earth spins on its axis once a day, making day and night, and its tilted axis causes the seasons. In maths, graphs and charts have a horizontal axis and a vertical axis, each with a label and a scale; coordinates are read along the x-axis first, then the y-axis. Phrases: x-axis, y-axis, axis of symmetry, spin on its axis.
examples
- Two vortices and an axis. (note 08) tree →
- It is two opposite turnings that have learned to become one movement — and, at the crossing point, the same upright axis that held 619 in balance, now folded into the middle of the figure. (note 08) tree →
- It is the axis that held 619 apart, the line through the middle of the 8. (note 10) tree →
- Put a 1 between them and you get 619: two vortices and an upright axis holding them apart, so neither swallows the other; balance, says the note, is not stillness but two opposite turnings that keep each other honest. (lesson 019) tree →
- In the note, 619 is two vortices and an axis: a straight line holding them apart so that neither swallows the other. (lesson 019) tree →
- The Earth spins on its axis once every 24 hours. tree →
- The Earth's axis is tilted, which gives us seasons. tree →
- Label the x-axis «days» and the y-axis «temperature». tree →
- The point (3, 5) is 3 along the x-axis and 5 up. tree →
- A square has four axes of symmetry. tree →
- Draw the axis of symmetry on the butterfly. tree →
- The bar chart's vertical axis goes up in fives. tree →
- A spinning top turns around its axis. tree →
note
Plural: axes (said «AX-eez»). Do not confuse with «axe/ax», a tool for chopping, whose plural is also spelled axes. In maths problems, read the scale on each axis carefully; the steps may be 2, 5 or 10, not 1.
In the corpora
- Earth's axis is tilted by about 23.4 degrees, and that tilt, not the distance from the Sun, causes the seasons.
- The Earth is a huge ball that spins around an imaginary line through its middle, called its axis.
- The Earth spins around its axis once in about 24 hours.
- The Earth's axis is tilted by about 23 and a half degrees.
- The axis keeps pointing the same way in space all year round.
