different dimensions briefly explained

1. DIMENSIONS

3. Definition
• In physics and mathematics, the dimension of
an object is defined as the minimum number
of coordinates needed to specify
any point within it.
• For example , a line has a dimension of one
because only one coordinate is needed to
specify a point on it .

4. So ,how many are there?
11 DIMENSIONS.
• The higher dimensions i.e. 7,8,9 &10 D are
based on probability and permutation.
• Since we live in 3D, we can visualize 0,1,&2 D.

5. Zero dimension
• A single point is known as zero dimension.

6. One dimension
• If we connect two 0 D objects by a line we get
the 1st dimension.
• It has only one fundamental unit i.e. length.

7. Two dimension
• Similarly ,if we connect two 1 D objects we get the 2nd
dimension.
• it has two fundamental units i.e. length & height.

8. Third dimension
• Like that, if we connect two 2D objects by lines
perpendicular to each other we get the 3rd
dimension.
• It has three fundamental units i.e. length, height
&width

9. Fourth dimension
• It has 4 fundamental units i.e. A hypercube
has a length, width, height and a fourth
dimension that is perpendicular to all three of
the other units.

performing a double rotation about
two orthogonal planes)

11. Tesseract
(The tesseract can be unfolded into eight cubes into
3D space, just as the cube can be unfolded into six
squares into 2D space. )

12. Scientists say that the
fourth dimension
perpendicular to the other
three dimensions is TIME

13. Fifth dimension
• In the fourth dimension time is just a
reference axis.
• But in fifth dimension we can travel through
space and time i.e. forward and backward in
time.
• Just like walking on the road we could travel
through time.

14. 5 D-cube (or penteract)

15. Sixth dimension
• In 5 D ,we can go forward and backward
through time and space.
• Now , in 6th dimension there is an axis
perpendicular to the space and time.
• i.e. if we consider the time line as 1D string
the axis perpendicular to it gives the 6th
dimension.

16. Sixth dimension
• The sixth dimension thus deals with the
multi- verse.

17. Why can’t we see
these dimensions?

25. Conclusion from the above story
The 2D square was not able to see(visualize)
the 3D pen.
We are bounded to or trapped in this 3D
world and we are not able to see the other
dimensional objects just like the square in 2D.
