Understanding a Joke
Hey mates!
Can anybody help me understand a 'nerd' joke?
I was reading the "Da Vinci Code" by Dan Brown and something caught my attention.
The context is, basically, the main character (Robert Langdon) is teaching a class about symbolism in art. And he mention the presence of the number PHI (1.618) in several ways in art and in nature as well. I wasn't familiar with this number, but they're kind of explaining the 'beauty' that surrounds it. PI (3.14) is pretty famous when studying circumferences.
So, here goes the extracted text:
Langdon turned to face his sea of eager students. "Who can tell me what this number is?"
A long-legged math major in back raised his hand. "That's the number PHI." He pronounced it <em>fee</em>.
"Nice job, Stettner," Langdon said. Everyone meet PHI."
"Not to be confused with PI," Stettner added, grinning. "As we mathematicians like to say: PHI is one <em>H</em> of a lot cooler than PI!"
Langdon laughed, but nobody else seemed to get the joke.
Seems to me that the guy is playing a pun on the letter H. As it is pronounced 'age' it sounds like "<em>PHI is one 'age' of a lot cooler than PI." </em>
I'm not sure, does it sounds funny for you? haha
Can anybody please explain it and, if it's not asking too much, correct my mistakes?
Thanks, you're awesome!! =)
