Accessible Lights

This sign appears at a lot of intersections in the Denver area, and I have absolutely no idea what it’s meant to signify:

Accessible Traffic Light

Accessible Traffic Light

Is the crosswalk wheelchair accessible? If so, why would drivers specifically need to know that? Is the rightmost lane of traffic designated for handicapped drivers? Perhaps the cross street features a wheelchair store? Wheelchairs can only cross the intersection when the rightmost traffic light is green?

Street signs are meant to communicate important information to motorists and pedestrians, and in this case I honestly have no clue what’s being communicated.

Spend Forever With Me… Starting Later

And now may I present: one of the worst ideas ever!

Will You Marry Me... Online?

Will You Marry Me… Online?

This (future) web service promises, “You can propose online with your very own proposal page that is made up of all the great information that you think is necessary.”

Flowers and champagne aren’t right for everyone. I don’t mean belittle someone whose perfect proposal might come riding a horse or sitting in a Chili’s. Proposals mirror the nature of the relationship, and there are a lot of different sorts of relationships. But surely we can all agree that a proposal — the suggestion that two people spend the rest of their lives together — should happen while actually together.

If it’s any consolation, the copyright notice reads 1997 to 2009, I came across this in 2010, and now in 2012 it’s all still “coming soon.” Perhaps traffic to the would-be online proposal service just isn’t what it might have been.

 

Government Help

Business owner Ray Gaster of Savannah, Georgia made headlines recently with a highly visible response to President Obama’s recent remarks about how government helps make commerce possible. Obama had remarked, “Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges. If you’ve got a business, you didn’t build that. Somebody else made that happen.”

Gaster’s response: signs hung prominently outside his three storefronts declaring that he built the business without any help from the government.

Government No Help

Government No Help

It’s a valid and powerful message… that completely misses the point. I like this annotated version itemizing some aspects of his business that Gaster clearly didn’t build himself:

Government Help

Government Help

Obama isn’t saying that everyone needs direct and explicit government help to start a business (e.g., with borrowed government funding), but rather that surrounding every business is a system of infrastructure, laws, and commerce that makes the endeavor possible.

The government built the roads carrying customers and merchandise, laid the wires that carry electricity and communications, established the police and fire departments that protect the building and its occupants from theft and disaster, and developed the civil justice system that provides recourse against fraud.

Critics of this image suggest the fallacy is that these things are all funded with taxpayer dollars, so it’s ultimately still the business owner paying for all of it. The trouble is that no one person’s tax dollars could fully fund all the services from street lights to sewer lines the government currently provides. Just hiring enough police officers to provide protection around the clock would use up every dollar I’ve paid in the past several years.

But private police forces are at least theoretically possible. (We could have a system where only people who have paid for police protection receive it.) Other government-run services are impossible to separate in that way. I could, for example, pay for the construction and maintenance of the roadway in front of my house, but that road is only valuable to me when it’s linked to other roads leading elsewhere in the city. If my neighbors don’t care about roads, how could I get across town?

Two years ago, Colorado Springs turned off its street lights, inviting residents who wanted the lamps relit to write a check to cover the cost of their lamp’s electricity. And while I’d be happy to pay for the electricity to the lamp outside my house, I like that when I go running in my neighborhood at night, every lamp is lit.

Ultimately the disconnect here is understanding the difference between what our government officials do and what government does. Maybe your roads are crumbling, your mayor is a crook, and your governor has been embezzling tax dollars for years — and there’s no excusing any of that. But their failures don’t eliminate the need to have a government of some kind. There are some things we just can’t do on our own: like building a business.

PEMDAS

Someone asked on Facebook: “5 + 5 + 5 – 5 + 5 + 5 – 5 + 5 × 0 = ?” Is it: (a) 40  (b) 0  (c) 20  (d) 15?

Take a moment to work it out. It’s not a trick question; it’s just arithmetic. Have you got it?

You will, of course, have seen that the problem could equivalently have been written as “5 + 5 + (5 – 5) + 5 + (5 – 5) + (5 × 0)”, which in turn is “5 + 5 + 0 + 5 + 0 + 0”, which is… 15.

As I write this, the Facebook poll shows these responses:

  • 2,225,250 answered
  • 981,309 people correctly answered 15.
  • 518,062 answered 20
  • 86,759 answered 40

This is sad in so many ways. First and most obvious is that the majority of respondents answered incorrectly. It appears they ignored operator precedence (or “order of operations” rules), did the addition and subtraction first, and then multiplied the final result by zero.

But I’m willing to attribute this in part to the context. This isn’t a scientific survey (in any way), and the question’s title invites poor thinking. After the mathematical expression, the question adds “(I Bet More People Will Answer It Wrong :P) Give A Try !!”

This identifies the question as a trick, so instead of simply computing the answer mathematically many people will just scan for the trick. Spotting the “× 0” at the end, they’ll leap to the conclusion other people would not spot that, and then jump straight to the 0 answer without ever evaluating the rest of the expression. So some of those 2,225,250 wrong answers are not from people who have forgotten about operator precedence, but from people who just didn’t put a lot of thought into a Facebook poll.

I’m more interested in the other two wrong answers. More than half a million people answered “20” which I imagine means they missed the “× 0” entirely and did just the addition and subtraction. Worse, many arrived at 40 which I can only conclude is the result of counting the fives and ignoring the operators (and the 0) entirely — i.e., treating everything as addition.

Let’s just all keep this in mind the next time your local school district asks for more money.

Boy Scouts of (Un-)America

The Boy Scouts of America supposedly spent the past two years reevaluating whether to allow gay Scouts and volunteers to participate in their organization. They decided against it.

“The vast majority of the parents of youth we serve value their right to address issues of same-sex orientation within their family, with spiritual advisers, and at the appropriate time and in the right setting,” said Bob Mazzuca, chief scout executive of Boy Scouts of America.

This logic is baffling mostly because it necessarily implies that gay people cannot be in a room with children without talking about sex. Granting unequivocally that parents want to discuss sex and adult relationships privately with their own children at home, shouldn’t these protesters also be worried about the conversations your straight leaders are having?

Perhaps more importantly, though, this rationale assumes that absent direct contact with an actual, “real life” gay person, children will never hear about homosexuality outside their home. My daughter wasn’t in Kindergarten more than three months before she came home asking if two boys could ever get married. That’s what Kindergartners do!

In Kindergarten Cop, on Arnold Schwarzenegger’s first day in a Kindergarten classroom, a boy stands up and proudly proclaims, “Boys have a penis; girls have a vagina,” to giggles from the rest of the class. In my daughter’s actual classroom I heard similar assertions about death, politics, mathematics, religion, spelling, clothing, pets, and family relationships. And apparently, one day, someone took ten seconds at recess to announce that sometimes two boys will marry each other.

Sometimes sheltering children from the complexities of reality is useful and warranted, but attempting to shelter children from the diversity of other people they’ll inevitably encounter in adulthood is both futile and harmful. However much good the Boy Scouts might do (and they do some considerable good), our society cannot tolerate any group that teaches children to discriminate and to exclude.

Not coincidentally, while the Boy Scouts spent the last two years deciding gay people are worthy of their group, I’ve spent the last two years refusing to participate in their organization in any way. Let’s watch the Boy Scouts decline into obsolescence as more tolerant groups rise to take their place. Perhaps the more tolerant Baden-Powell Service Association is our first step?

Too Many Notes

Futility Closet shares a humorous report an “organization and methods engineer” wrote about a concert at Royal Festival Hall:

For considerable periods the four oboe players had nothing to do. Their numbers should be reduced, and the work spread more evenly over the whole of the concert, thus eliminating peaks of activity.

All the twelve violins were playing identical notes. This seems unnecessary multiplication. The staff of this section should be drastically cut; if a large volume of sound is required, it could be obtained by means of electronic amplifiers.

(The full report, only a few paragraphs long, is worth a look.)

While the piece is obviously intended for humor, what’s most striking to me is the realization that at some point in the evolution of music someone must actually have said, “I know what would make this better: two instruments playing the same notes simultaneously!” And that crazy idea turns out to be entirely valid.

Bridge Road

Google Maps shows here Moretown, Vermont’s “Bridge Road”:

Bridge Road

Bridge Road!

I can’t help but feel that something is missing from Bridge Road, though… Let’s try the same image without the labels:

Bridge Road?

Bridge Road?

This is the stuff GPS-instigated disasters are made of.

For Your Safety

Disneyland used this graphic frequently, including this instance in line for the Dumbo ride. It appears that holding hands is encouraged, but dancing jigs while preparing to leap headfirst from the ride vehicle is discouraged.

The safety implications are real and important, but the pictorial version just made me laugh every time.
