Query: Three pearls of Bernoulli numbers   The Bernoulli numbers are fascinating and ubiquitous numbers, they occur in
several domains of Mathematics like Number theory (FLT), Group theory, Calculus
and even in Physics. Since Bernoulli's work, they are yet studied to understand
their deep nature and particularly to find relationships between them. In this
paper, we give, firstly, a short response to a problem stated, in 1971, by
Carlitz and studied by many authors like Prodinger \cite{PRO}, the second pearl
is an answer to a question raised, in 2008, by Tom Apostol .The third pearl is
another proof of a relationship already given in 2011, by the authors.
