My lecturer today was trying to give a “real world example of aperiodic signals”. Which was:
“Remember in the movie Independence Day, when the aliens were sending the signal to Earth?”
Going to stop you there professor…not really a real world example is it? A, It’s a movie. B, they’re aliens. If that’s really the best example you can give…why are we learning it? Are we going to learn about any of the other technology the aliens used in the ‘96 Sci-Fi adventure?

I hate losing stuff, or that sensation and moment of panic when something isn’t where you think it’s supposed to be. I’m a fan of the quick pocket tap, left pocket wallet, right pocket phone. The iPod can get me, because it really doesn’t have a loyalty to any pocket, so the sudden panic when I realise it’s not in my left pocket, is quickly alleviated when I tap and feel it in the right. Sometimes it can be tricky, its flat so can sometimes pair up with the phone or the wallet, and just feel like one item is in each pocket; which is then followed by the panic stricken; “oh my god where is it?”
There is usually 3 seconds of chaos, frantically checking pockets, thinking where it could have fallen out of my pocket, checking bag, looking at the path behind me desperately hoping that I’ve continently happened to drop it in the last 10 steps. After 3 seconds I stop and compose myself.
“Relax Steve, there is music playing in your ears. Just calmly trace the cord from your earphones, to the iPod in your pocket. Crisis averted.
