Small things - 28 Oct

• Black holes matter.
• Has anyone (who isn't trained in physics) ever wondered why (specifically) the 'speed of light squared' is the conversion factor for converting mass to energy? What does the speed of light have to do with it?
• Next time you cut the grass (with a self-propelled mower), just tie the lawnmower by a string to a post in the middle of the yard and just let it go on its own. It'll just keep mowing smaller and smaller circles.
• I've never gone under the knife, but if I did, I know that as soon as I woke up, I'd be calling out weakly, asking "What's the wi-fi password?"
• If it costs an arm and a leg, you can expect severe buyer's remorse down the road.
• Remember that time when you accidentally set fire to the field across from school while playing hookey? No? Oh, that was just me?
• Imagine if we watched and commented on cooking shows the same way we watch and comment on televised sporting events.
• The problem with trying to talk on the phone while on the toilet is that eventually, you're going to have to explain the other noises that will present themselves. Either that, or you'll have to explain the inherent echo that comes from talking in the bathroom.
• A picture may be worth a thousand words, but good luck finding someone to come up with the thousand words.
