3 Books You Should Read To Understand 4D aka ‘The Fourth Dimension’

We all have heard of this but no one actually does know “What 4D is or How does it look like?”.

Some people think that it’s the dimension of Time and some think that it’s the dimension of Space but no one, including the best minds in the world, is sure about that.

So trust me when I say that if you’re a greedy geek in Physics and Maths like me then you’re gonna love this topic.

First of all, let’s see a PROJECTION of 4th Dimension in our 3D world on a 2D screen:

I can explain to you what 4D actually is, but no matter how hard I try I can never make you understand the way this man did in this video.


But what I can do is suggest you the books you should read to learn more about ‘What 4D is?‘.

So, first of all, understand what 4D is and then below the video, I’m gonna put my suggestions:

Ok, so now when you know what 4D is, let’s just dive a bit deeper and explore a few books on the fourth dimension:

1. Flatland

A Romance of Many Dimensions

Flatland: A Romance of Many Dimensions by Edwin A. Abbott

Written by Edwin A. Abbott, this book is actually a journey of a SQUARE (Geometrical figure with 4 sides & 4 corners) who lives in a 2D aka Two-Dimensional Flatland.

Flatland gives you a perspective of Square of 3D and 1D and 0D world.

The thing that amuses me the most about this book is that it was written in 1880. Yes, you heard me correct!!! 1880. That means it was written before the discovery of ‘The Theory of Relativity‘ by Einstein.

2. Sphereland

A Fantasy About Curved Spaces and an Expanding Universe


Sphereland: A Fantasy About Curved Spaces and an Expanding Universe by Dionys Burger


Written by by Dionys Burger, Sphereland is the sequel of the book we just talked about i.e., Flatland.

It is an update to its prequel which was written in 1880 and obviously has flaws, but that doesn’t mean this book is IDEAL.

I like Flatland more than this one but still, it is good enough to be on this list.

Also, read: Is Time Non-Linear?

3. The Fourth Dimension

Toward a Geometry of Higher Reality by Rudy Rucker

The Fourth Dimension: Toward a Geometry of Higher Reality by Rudy Rucker

This is the best book you can ever read on the Fourth Dimension.

It busts all the myths that exist regarding the 4th dimension.

The Fourth Dimension is written so simply so that anyone can read it and trust me you don’t even have to know Math for reading this 😉

So, this was our recommendation list on books to understand the fourth dimension (4d books) better.
