Want a happy holiday? Pray for an Arctic blast Telegraph tells numerate readers.


Dr Arnall’s hap­pi­ness for­mula is: O + (N x S) + Cpm/T + He. Put more simply, a numer­ical value for being out­doors (O) was added to nature (N) mul­ti­plied by social inter­ac­tion (S), added to child­hood sum­mer memor­ies and pos­it­ive thoughts (Cpm) divided by tem­per­at­ure (T), and added to hol­i­day excite­ment (He).

So explains the Daily Telegraph. When divid­ing a smal­ler denom­in­ator gives a big­ger num­ber. 1/10 is a big­ger num­ber than 1/100 des­pite 100 being big­ger than 10. When T approaches zero Cpm/T approaches infin­ity. Dr Arnall is we will be hap­pi­est when T = 0. That’s a sum­mer where the tem­per­at­ure hits freez­ing point if you’re meas­ur­ing in Centigrade,* when you’ll be infin­itely happy. If you’re meas­ur­ing in Fahrenheit you’ll be euphoric when the tem­per­at­ure reaches the equi­val­ent of –18ºC.

What’s pain­ful to read is that he doesn’t seem to under­stand his own for­mula. He’s quoted as say­ing: “June has also seen some warm weather after the cold spring, with people hop­ing more warm spells are ahead,” without warn­ing that in his fantasy this warm weather would be less pleas­ing than cold and drizzle.

*Anders Celsius ori­gin­ally set his scale the other way round, so that boil­ing point was 0º and water froze at 100º. Despite this, I strongly doubt Dr Arnall would he happy if someone tripped and spilled the con­tents of a boil­ing kettle over him.
