How to draw 4, 5, 6 and 7 dimensional objects. 1 point has 0 dimensions. Double the points. And you have 1 dimension. Double the points again. And you have 2 dimensions. Double the points again. And you have 3 dimensions. Double the points again. And you have 4 dimensions. Skeptical. You're watching this on a flat 2 dimensional computer monitor. In 2 dimensions, it's not possible to have 3 axes, each of which is 90 degrees to the other 2. Yet we accept this picture as a representation of 3 dimensions displayed on a 2 dimensional monitor. In 3 dimensions, it is not possible to have 4 axes, each of which is 90 degrees to the other 3. Yet as with 3 dimensions on a 2 dimensional monitor, we can accept that this is a representation of 4 dimensions. If you remove any one of the 4 axes, you will go back to 3 axes, each of which is 90 degrees to the other 2. Therefore each of the 4 axes is 90 degrees to each of the other 3. Therefore, each of the four axes is 90 degrees to each of the other three. In the same way, we can add a fifth, sixth, or seventh axes, each of which is 90 degrees to all the axes that came before it. Double the points again. And you have five dimensions. By continuing to double the points, you can add as many dimensions as you want. Six dimensions. Seven dimensions. Therefore, we can draw as many dimensions as we want.
