I was on the train the other day and I saw a funny t-shirt that said:
Resistance is futile
(if < 1 ohm)
Now, you need to understand a few things to get the humor on this shirt.
First, the phrase "resistance is futile" is from Star Trek. The Borg are a fictional pseudo-race of cybernetic organisms depicted in the Star Trek universe. The Borg have become a symbol in popular culture for any juggernaut against which "resistance is futile".
Next, the < 1 ohm is physics. The ohm (symbol: Ω) is the SI unit of electrical resistance, named after Georg Simon Ohm. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.
Now, I'm not entirely sure if this shirt is scientifically accurate, but it caused me to chuckle and smile as I thought about my college days at MIT. My wife and I had some really nerdy t-shirts that were full of mathematical equations and formulas. We now have baby t-shirts that say "QT pi <pi symbol>"
You can get this shirt from ThinkGeek. Why do I get a feeling that my kids will buy future Father's Day gifts from ThinkGeek?
