I Tripped

Ever been walking and caught your toe on the ground and stumbled forward for a moment? Maybe you fell to the ground, maybe you caught your balance immediately and everything was fine after?

Regardless of how it turned out, you immediately looked back at that spot on the floor, didn't you?

Of course you did. This is the arrogance of humanity. Think about this: It took you (probably) somewhere between 12 and 18 months to learn how to walk. People who suffer spinal injuries lose the ability in an instant, and those who get it back have to re-learn and that takes a tremendous amount of time as well.

Think about how amazing it is that you can walk at all. How many other animals on the planet use two legs as their primary form of movement? There are lizards that run sometimes, ostriches (although the other birds all prefer to fly), maybe some kangaroos or hopping-rodents - but even those are primarily by hopping. There are approximately 6.5 million species on land. We can be generous and suggest that maybe 10 habitually, consistently move by walking or running on two feet. That means that if you're a living thing on Earth, you have about a 650,000:1 chance of being something that moves by walking. Pretty long odds.

Next, if you think about the mechanics of it, walking is outrageous. When a pigeon walks, you'll notice that its head jerks about with each step it takes. Why? Because pigeons are constantly strutting and are obnoxious, that's why. But also because it's a delicate act to balance weight on two feet while moving. But don't take my word for it, take someone smart, like Leonardo Da Vinci, who once said "The human foot is a masterpiece of engineering and a work of art." And he knew stuff about engineering and works of art (as I've discussed at other points on this blog).

Why not look at this in a different way: Ever played the QWOP game? It's simple: You use four keys to control the runner - Q and W control the thighs while O and P control the calves. Pump them appropriately and your QWOPper will run 100 meters and win the Olympics for...some country. It's an oversimplified version of what's happening when you walk or run, as the game asks you to control just four body parts. A brief look at Google results suggests that it takes approximately 200 muscles to walk in real life, which is slightly more than four.

So go ahead and look back at the carpet monster that tripped you. There's not a bump in the floor or a mislaid tile or a little hand that came up to grab your shoe. It's just that walking is an unbelievably difficult thing to do when you break it down. So cheer up, because you probably won't be able to walk under your own power for the last few years of your life either, which makes it special that you ever could.

Oh, my best on QWOP  was like 12 meters. Running is hard.

Shenandoah, Northern Virginia, and Racists

Jenna and I spent a chunk of this week in Northern Virginia, in the area around Shenandoah National Park. Shenandoah (which it turns out I've been pronouncing incorrectly for my entire life) was great. There were hikes of all levels and lengths, varying difficulty, varying crowd-levels, and lots more. The park wasn't in full-swing yet, as some of the camping areas don't open until "summer," but there were still plenty of people out enjoying nature, which is nice. Being in nature gets me thinking. After a day of driving along Skyline Drive and doing several small hikes, we hiked a trail called Bearfence . After an incredibly fun scramble up the rocks to the actual peak, we were greeted with what I can only imagine is the best lookout point in the entire park. Sitting on top of a mountain - looking over dozens of other mountains - is a special feeling. As tiny houses in tiny faraway towns fill your vision, you start to think about how those are just people. From...

How do you pick a place?

Traveling is good. Traveling does things to you that staying in one place cannot. But traveling poses one of the most difficult questions that a person can be faced with: Where do you want to go? Most people have a list of places that they'd like to go. Depending on your station in life, that list might include Paris, Tokyo, Disney World, Bora Bora, or Branson, Missouri - all of which are fine choices, if given the right set of circumstances. But that list is probably longer than one place, and you're almost certainly not spending an unlimited amount of time in whichever place you choose, so how you do decide where to go and what to do while you're there? The truth is that it's hard. I'm lucky, I know it. I've been a lot of places - more places than were originally on my "I have to go there before I die" list, if I'm being honest. And yet, I still want to go places. Every time one place gets crossed off the list, another place gets added. Wh...

Hyraxes and Elephants and Africa

Sometimes you read things online that can't be true. Sometimes those things turn out to be true. About a year ago I read that the hyrax is the closest living relative to the elephant. The hyrax is roughly the size of a domesticated rabbit - maybe smaller - and looks like a mix between a capybara and a rat. Here is its wiki page . It's amazing. The genetic similarities (if you don't read the wiki page) are because they have similar testicle situations (great band name), their mammaries are patterned in a way that's similar to manatees and elephants, and their "tusks" come from the incisors (same as elephants) whereas almost all animals have "tusks" from their canine teeth. How can something that maxes out at about 10 pounds be nearest relative to something that weighs about 200 pounds at birth? Science is amazing. And while I do want to explore how the above question can be answered, I'll do that on my own time or read about it on the intern...
