“To paraphrase Oedipus, Hamlet, Lear, and all those guys, “I wish I had known this some time ago”*…




“Irony” is a term that everyone uses and seems to understand. It is also a concept that is notoriously difficult to define. Much like Winona Ryder’s character in the 1994 rom-com “Reality Bites,” whose inability to describe irony costs her a job interview, we know it when we see it, but nonetheless have trouble articulating it. Even worse, it seems as if the same term is used to describe very different things. And following your mother’s advice — to look it up in the dictionary — is liable to leave you even more confused than before.

Uncertainty about irony can be found almost everywhere. An American president posts a tweet containing the phrase “Isn’t it ironic?” and is derided for misusing the term. A North Korean dictator bans sarcasm directed at him and his regime because he fears that people are only agreeing with him ironically. A song about irony is mocked because its lyrics contain non-ironic examples. The term has been applied to a number of different phenomena over time, and as a label, it has been stretched to accommodate a number of new senses. But exactly how does irony differ from related concepts like coincidence, paradox, satire, and parody?…

A handy guide to distinguishing the notoriously slippery concept of irony from its distant cousins coincidence, satire, parody, and paradox: “What Irony is Not,” excerpted from Irony and Sarcasm, by Roger Kreuz.

As we choose our words, we might recall that it was on this date in 1483 that Pope Sixtus IV consecrated the Sistine Chapel (which takes its name from his) in the Apostolic Palace, the official residence of the Pope in Vatican City.  Originally known as the Cappella Magna (Great Chapel), Sixtus had renovated it, enlisting a team of Renaissance painters that included Sandro Botticelli, Pietro Perugino, Pinturicchio, Domenico Ghirlandaio and Cosimo Rosselli to create a series of frescos depicting the Life of Moses and the Life of Christ, offset by papal portraits above and trompe-l’œil drapery below.  Michelangelo’s famous ceiling was painted from 1508 to 1512; and his equally-remarkable altarpiece, The Last Judgement, from 1536 to 1541.

“Once is happenstance. Twice is coincidence. Three times, it’s enemy action.”*…



A couple of weeks ago, we considered the human urge to find significance, meaning in everyday occurrences: “All mystical experience is coincidence; and vice versa, of course.” Today, we consider the same phenomena from a more mathematical point-of-view…

Was it a chance encounter when you met that special someone or was there some deeper reason for it? What about that strange dream last night—was that just the random ramblings of the synapses of your brain or did it reveal something deep about your unconscious? Perhaps the dream was trying to tell you something about your future. Perhaps not. Did the fact that a close relative developed a virulent form of cancer have profound meaning or was it simply a consequence of a random mutation of his DNA?

We live our lives thinking about the patterns of events that happen around us. We ask ourselves whether they are simply random, or if there is some reason for them that is uniquely true and deep. As a mathematician, I often turn to numbers and theorems to gain insight into questions like these. As it happens, I learned something about the search for meaning among patterns in life from one of the deepest theorems in mathematical logic. That theorem, simply put, shows that there is no way to know, even in principle, if an explanation for a pattern is the deepest or most interesting explanation there is. Just as in life, the search for meaning in mathematics knows no bounds…

As we consider the odds, we might send carefully-calculated birthday greetings to Johann Bernoulli; he was born on this date in 1667.  A member of the mathematically-momentous Bernoulli family, Johann (also known as Jean or John) discovered the exponential calculus and (with Leibniz and Huygens) the equation of the catenary.  Still, he be best remembered as teacher and mentor of Leonhard Euler.

“All mystical experience is coincidence; and vice versa, of course.”*…




Today, nearly all scientists say that coincidences are just that: coincidences – void of greater meaning. Yet, they’re something we all experience, and with a frequency that is uniform across age, sex, country, job, even education level. Those who believe that they’ve had a ‘meaningful coincidence’ in their lives experience a collision of events so remarkable and unlikely that they chose to ascribe a form of grander meaning to the occurrence, via fate or divinity or existential importance. One of the most commonly experienced ‘meaningful coincidences’ is to think of your friend for the first time in a long while only to have her telephone you that instant. Any self-respecting statistician would say that if you tracked the number of times you thought of any friend, and the number of times you had that friend immediately ring you, you’d find the link to be statistically insignificant. But it is not necessarily irrational to attribute grander significance to this occurrence…

Lightning can strike twice and people do call just when you’re thinking of them – but are such coincidences meaningful?  Find out at “On coincidence.”

As we muse on meaning, we might ponder the significance of the fact that on this date in 1817, the exquisite novelist of English manners Jane Austen passed away– six years to the day after the birth of William Makepeace Thackeray, who was in such works as Vanity Fair her successor as chronicler of English society (born on this date in 1811).  Coincidence?
