Bedtime Story 


Galois's Paper Failed to Impress his Peers


In comparison with Gödel, Galois was highly unfortunate because no one around him, even the best of the minds, was able to grasp his work.

He failed to grasp the attention of his peers that he rightfully deserved.

Moreover, the paper was Galois was a very difficult one, much like the Gödel’s incompleteness theorems though Gödel was fortunate in that he was surrounded with dazzling mathematical minds including John von Neumann who immediately grasped the significance of the work and exclaimed “It’s all over”.                  

If what I am trying to explain to you about Galois goes over your head, you need not take it to your heart for Galois’ paper that was finally published in 1846 by Joseph Liouville made little sense for his own mathematical contemporaries; those men who did mathematics day and night for a living and out of love for it.

Even Liouville who himself published the paper and praised it lavishly for its originality completely failed to grasp the group-theoretic basis of it. 

Serious mathematicians such as Cayley in England, Kronecker and Dedekind in Germany who were the European stalwarts of mathematics completely failed to appreciate the genius of Galois in spite of being aware of his work.

It was only in 1880s and 1890s when mathematical text books written by Eugen Netto and Heinrich Weber (both Germans) gave their due respect to Galois’ work that his work came to know to the wider audience both in the continent and across the Atlantic.

So now let us jointly try to understand Galois’ work.

Let me break down the problem of understanding Galois Theory in some simpler smaller problems and questions, something in the lines of ‘divide and conquer’ technique used both in military warfare/politics as well as phacoemulsification method of cataract surgery.

What does group of any sort has to do with solvability or rather non-solvability of quintic or higher degree polynomials in terms of radicals?

If the Abel-Ruffini theorem makes it clear that quintic or higher degree polynomials have no solutions in radicals, then what is further left to discuss or tackle?

I think I had given you a hint of the small gap that was still left behind which to most apes would not be of much consequence but it certainly did bother Galois.

It turns out that there are some quintics or higher polynomials that do have a solution.

At this point we need to go back and read what Abel philosophized about any mathematical problem.

Abel rightly pointed out (to the top class mathematical brains who indulge themselves in the frontiers of unknown math) that any mathematical question or problem (such as a possible proof of Riemann Hypothesis) should be posed not merely to arrive at its solution but also in a fashion that would suggest whether arriving at its solution is at all possible.

We shall attack this problem of Galois Theory in the nights to come.

Another great educator and a teacher that I am aware of is Professor Subhashish Chattopadhyay in Bangalore, India.

While I narrate stories, Professor Subhashish an electronic engineer and a former professor at BARC, does and teaches real mathematics and physics.

He started the participation of Indian students at the International Physics Olympiad.

Do visit him here:


All his books can be downloaded for free through this link:
