Bedtime Story 


What Bothered David Hilbert also Concerned Two Englishmen Alfred North Whitehead and Bertrand Russell


David Hilbert had spoken these famous two lines on September 8, 1930 at the annual meeting of the Society of German Scientists and Physicians.

These words reflected his optimism of generating that perfect self-contained, consistent and complete formal mathematical system bereft of any flaws, paradoxes and indecisiveness.

One of the first serious attempt to create such a perfect and comprehensive mathematical system was the 1910 three-volume treatise by Alfred North Whitehead and Bertrand Russell.

Agreed that Giuseppe Peano did it before them, but his work was neither as voluminous nor as comprehensive as theirs though it must be said that Peano’s work was one of the inspirations for these men to work on this book.  

Both these gentlemen were English, mathematicians, logicians and philosophers, all in one.

Russell was the younger of the two and in fact was a student of Whitehead at the Trinity College in the 1890s.

This three-volume work of these two great minds goes by the name of Principia Mathematica and is considered one of the greatest intellectual feats of the twentieth century.

Modern Library, the American publishing company ranks Principia Mathematica 23rd in the list of top 100 English-language non-fiction books.

In a way, Principia Mathematica that I shall abbreviate to PM since it will come several times, was a product of extreme uneasiness and discomfort with the prevailing state of mathematics of those times (late 1800s and early 1900s) and whose (state of mathematics) most vocal proponent was David Hilbert.

It was essentially an attempt to reduce mathematics to pure symbolic logic.

That means even the set of axioms and inference rules were reduced to symbolic logic and starting from them, attempt was made to prove all of the known mathematics.

Just the nature of task that was attempted and carried out calls out for immense respect towards these gentlemen.

The work dealt only with the set theory, cardinal numbers, ordinal numbers and real numbers.

A fourth volume on the foundations of geometry was thought out but by the end of the three volumes, these two remarkable men were overwhelmed with intellectual exhaustion.

Yet they convinced the world that in principle, almost all of known mathematics could be derived from this formal symbolic logic.

This work is almost or is essentially deduction of mathematics using pure logic.

 One of the most memorable fact of this painstaking tedious work that is often spoken about is that it took more than eighty pages into volume 2 to prove that 1 + 1 = 2.

This is stated as a proposition and is followed with a comment:
 “This proposition is occasionally useful”.

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.
