Our revels now are ended. These our actors,
As I foretold you, were all spirits, and
Are melted into air, into thin air:
And like the baseless fabric of this vision,
The cloud-capp'd tow'rs, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all which it inherit, shall dissolve,
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on; and our little life
Is rounded with a sleep.

De super cordis - On superstrings

Having read Brian Greene's "The elegant universe" and thumbed through his "The Hidden Reality", I feel the irresistible urge to paraphrase a well known sentence(*) as

"When all you think of are strings, every solution looks like a knot"

*)"When all you have is a hammer, every problem tends to look like a nail"

Avendo letto "L'universo Elegante" e aver sfogliato "La realtà Nascosta" di Brian Greene, non posso evitare di parafrasare un famoso detto(*):

"Quando tutto ciò a cui pensi sono stringhe, ogni soluzione sembra un nodo"

*) "Quando tutto quello che hai è un martello, tutti i problemi ti sembrano chiodi"
