The earliest robo-death was Robert Williams. He was killed in a Ford plant in Flat Rock, MI by a robot. It was a parts fetching robot. It wasn't fetching fast enough so Robert Williams was sent back to get a part. The robot didn't see him and killed him because he was standing in the way. This led to some of the first case law in robo-ethics. It seems his family sued the manufacturer of the robot for not programming it not to kill. They were awarded $10 million (over $31 million in today's money), Michigan's largest personal injury settlement at the time.
Two years later at a Kawasaki factory in Japan, Kenji Urada, a maintenance engineer, was shoved into a grinder by a robot and killed. Because it was Japan, there was no personal injury lawsuit.
Perhaps these stories will be in the history books our robot overlords make us read.
There's a great site that lets you see the hit count for any Wikipedia article. Saharan silver ant was featured on the front page of Wikipedia (in the "Did You Know..." section) on May 19th. On that day, it got 4,400 hits. The next day it got 3,500 hits. The next day it got 131. How fickle fame can be.
A survey of about 50 female University students revealed that
the ideally dressed man wore a checked jacket, gray slacks, a
bright plaid tie and socks and white shoes. Bow ties, stiff collars
and black shirts elicited a largely negative response.
The survey indicated that a slight majority favored the wearing
of hats on dates, but derbies were widely frowned upon.
Derby hats frowned upon? I guess I don't want to live in 1935.
Here's an interesting chart showing the market and non-market labor of men and women in a bunch of different countries.
Things to notice: Women in the Netherlands do more non-market labor than any other group, although women in Nepal, Kenya, and Indonesia do more work overall.
Men and women in the US, surprisingly, do similar amounts of work. Men in the US and UK do similar amounts of work, but women in the UK do more non-market labor than their US counterparts.
I'm sure you'll discover your own interesting facts in this chart. (Click for larger.)
It seems "John Coddington" of the 1600's is John McCain's
great-great-great-great-great-great-great-great-great grandfather through three separate
lineages. That means some cousins married at some point in the past 400 years of McCain
history. John McCain: If we can't trust his cousins not to marry, how can we trust him to
kick the special interests out of Washington?
I sent the first graph to a friend and he replied "Republicans must be better for income." That is clearly the opposite of what it says, so I tried to figure out how he misread it. I think he thought the x axis was time and the y axis was total growth. But it isn't. The income quintiles are in the x axis and percentage growth is the y.
Interestingly the income growth for the highest earners is the same in Democratic and Republican administrations. I guess they have it all locked up.
I've charted here the taxonomic relationships between fifty animals you are likely to either encounter in North America, or wonder about. No ungulates, though. Because who cares about ungulates? “Look at me, I support my weight in the tips of my usually hoofed feet.” Nope, no ungulates.
The chart is kind of self explanatory, but it does leave out the classification “suborder.” The interesting thing to note about this is in the order carnivora, the two suborders are feliformia, the cat-like carnivores, including cats, hyenas, and mongooses (mongeese?), and caniformia, the dog-like carnivores, which include dogs, bears, skunks, walruses, and weasels and their allies.
It's kind of hard to read, so click the chart for a larger image.
Next, if we view this next to his emails to me, which have a mean of .77, we see it is not all that different.
So how about you crunch the numbers before you complain, eh?
(Although, one of the reasons I started the blog was so that I didn't have to email amusing things anymore.)
In the 1960's, import substitution industrialization was all the rage. Developing countries were trying to develop their own products for their domestic market. Watch these two videos by Ha-Joon Chang for why this is a good idea.
It seems Mexico had a nationalized auto company called VAM, or Vehiculos Automotores Mexicanos. This is very clever because “vam” is close to the Spanish word for “to go.” (Contrast with the Chevy Nova, which translates into Spanish as “doesn't go.” While this isn't true, why let “facts” get in the way of a good story?)
VAM started in 1963 as a venture between the Mexican government and AMC. (This involved nationalizing Willys Mexicana, which had been producing Jeeps and other AMC designs since 1946.)* Mexican law required them to source at least 50% of their parts locally. This is because they were communists who hated the free market. Most of their cars were AMC designs that were modified to work with lower octane fuels, and other Mexican conditions.
By 1982, a recession in Mexico and a devalued peso led to the company being sold to nationalized French company Renault (who had a relationship with AMC) for negative 200 million dollars. That's right: the Mexican government paid Renault 200 million to take VAM off their hands. Renault, of course, shut down VAM. (AMC itself was bought by Chrysler in 1987, who discontinued the brand, although certain models, such as the Jeep, continued being produced by Chrysler.)
So if you ever seen an AMC Gremlin with Mexican plates running on low octane fuel, give a salute to VAM.
Also, check this link for some VAM magazine ads from the '70s.

Down the street from where I live is a pizza place that also serves shakes. What is notable is that there are 18 flavors, and they allow the customer to combine shake flavors in any way the want. Every time I go in, I wonder how many possible shakes there are. I searched the combinatorics literature, and didn't find one equation that would answer this problem. So I needed to invent one.
My starting point was the “choose” function. This is for calculating total combinations without repetition. The formula is , where n is the number of objects from which you can choose and k is the number of objects to be chosen. If we were to calculated 18 choose (2), this would tell us how many two-flavor shakes can be made with 18 flavors. But we want to know how many combinations there are if you can choose between 1 and 18 of the eighteen flavors. So we need to add 18 choose functions.
At this point someone pointed out to me the “vanilla” isn't really a flavor, because it is just the ice cream with no flavor added. So I modified it to 17 elements, but choosing 0 is valid.
Something for the math-clever among you to consider: If we replace k in formula two with 18, the result doubles. Why is it that increasing the number of elements by one always doubles the result? (Also, does anyone know a better way to write formulas in blogger?)
I read on the Wikipedia about the “Gimli Glider” incident. Apparently it was a culmination of multiple errors. The way I understand it, the Boeing 767 had two redundant fuel gauges. Howver, it was a new craft and they were still working out the kinks. On this particular 767, the fuel gauge wouldn't show the correct level if both were function, so the mechanic pulled the breaker on one of the gauges. Next, a mechanic at the next stop reset the breaker and forgot to notate it. Also, they were using the wrong conversion factor between kilograms and liters of fuel. They used the conversion factor between pounds and gallons. So they had around half what they thought they did. You can see what's about to happen. The plane runs out of fuel at 41,000 feet. The pilots then glide the aircraft to a military airstrip that was at the time set up for a “Family Day” drag race. They landed nevertheless. The van of mechanics sent from the nearest airport to the impromptu landing, coincidentally, were delayed when the van ran out of fuel.
A similar case involved an Airbus A310. It couldn't raise it's landing gear all the way, and it's computers calculated fuel consumption as if the landing gear were up. It ran out of fuel 20 km away from it's destination. They glided it to the runway, landed short and totaled the plane. No one died.
Sometimes nature can turn a powered craft into an unpowered glider. A Boeing 747 flying near Java flew through a volcanic ash cloud. Engines, it turns out, don't like being flown through volcanic ash clouds. In protest, they flamed out. The pilots had to glide 261 km. Being British, they announced this as “Ladies and Gentlemen, this is your Captain speaking. We have a small problem. All four engines have stopped. We are doing our damnedest to get them going again. I trust you are not in too much distress.” I wouldn't tell the story if they crashed, so you know the ending. Why did they fly through an ash cloud? Because it didn't show up on their weather radar. Thanks, computers.
Our final story of “planes that really shouldn't be used as gliders” is a Airbus A330. This time, the mechanic “upgraded” a hydraulic line, but use the wrong part. He told his boss it wasn't the right part, but he said to use it anyway. This left not enough room between the hydraulic and fuel lines. The hydraulic line vibrated enough to cause a fuel leak in the fuel line. The pilots, while over the Atlantic, noticed a fuel imbalance between the two tanks, so they opened the cross-feed valve. This just poured their fuel from the good tank to the leaky tank. Consequently, they ran out of fuel and had to glide to an airbase in the Azores. What I want you to do is find a map and find the Azores. Notice how much nothing there is surrounding them? They were pretty lucky they were within distance. Not much to land on in an ocean.

Interesting correlation: When confidence in the military is high, confidence in organized religion is low. It seems you can only worship at one alter.
See? (Like that linear regression?)
Also interesting: big business and organized labor both have similar confidence levels throughout the history of the poll. This year, they were tied at 20%.

Those of you who know me know that my favorite currently producing musician is probably M. Ward. He recently made a new album with Zooey Deschanel that is pretty great. Here's a clip of them playing on Late Night with Yo La Tengo. I find it sounds more than a little like Phish. The piano especially.
Here's an even better clip of M. Ward and Zooey Deschanel, this time on the Late Late Show:
It's no secret that I'm not particularly fond of the Clinton Administration. However, I did hear one story that warmed my heart: Webster Hubbell, associate attorney general under Clinton, wrote in this autobiography that Clinton once told him the following: “Webb, if I put you over at Justice I want you to find the answers to two questions for me. One, who killed JFK? And two, are there UFOs?”
Shortly afterward, he pushed through NAFTA, invaded Iraq, demolished welfare, and committed war crimes in the Sudan.
If you're like me, you often find yourself wondering about the state of the Japanese adult film industry. And where for us to turn but Time Magazine.
Learn about a 74-year-old man that has starred in over 350 “elderly” adult films. Apparently his kids don't know. Or maybe they are just too embarrassed to mention that they saw one of his films.
If you are worried about the lack of arch support, read this.
It is said that the Tarahumara, an indigenous group in northern Mexico wear tire sandals.
Apparently Nissan has made the first Japanese supercar. And British motoring show “Top Gear” raced it across Japan. Against the Bullet Train. I would tell you the amazing features of the GT-R, but you're just going to watch the video, so I'll leave it at that.
As Spinal Tap reminds us, there is a fine line between clever and stupid.
I saw this small wind turbine on Internet. You strap it to yourself or your bike and it recharges your, for instance, iPod. If you can keep up a pace of nine miles per hour, it can give you thirty minutes of charge for every twenty minutes of wind. Clever or stupid: you weigh in.
I heard about a company in South Africa called Township Guitars that makes guitars out of motor oil cans. Apparently there is some debate about whether townshipguitars.com or townshipguitar.co.za is the real Township Guitars. I throw my support behind .co.za because they seem to be higher quality.
As you know, however, I cannot see something cool without attempting to copy it. I therefore embark on a motor oil can guitar journey of my own.
The original is made out of a 5-liter Catrol GTX can. I bought a 1 gallon vintage Singer oil can on ebay. It is slightly smaller, but I like the look. I also acquired a P-90 pickup, and a stop-tail bridge. I should be pretty good. Watch this space for details as it unfolds.
I have an economics professor who is prone to cryptic off-hand statements that don't get explained. One day in class he was presenting a model in which a firms “effective” workers depends on their wage rate relative to the market wage rate. And unemployment got worked in there. (So if there is high unemployment, people are afraid to lose their job, and you don't have to pay them much to get a lot of work out of them.) Out of nowhere, the professor comments that when he was an adviser to Richard Nixon in 1970, there was a concern that the unemployment rate was too low and that “the guys down in Lordstown would start sabotaging Chevy Vegas,” and that it was therefore a goal of Nixon's to raise the unemployment rate.
I had a hard time dissecting this statement, but I think I've made some progress. If you understand a “labor extraction” model of wage determination, you know that the wage is always higher than would allow full employment. In fact, if it were at full employment, there would be the “whistle while you work” level of labor extraction. No one would work hard because they would get another job easily if fired. So perhaps Nixon was concerned that the unemployment rate was so low, people had no fear of getting fired, and this could lead to a revolution situation, wherein the workers at Chevy's Lordstown Assembly plant in Lordstown, Ohio would start to sabotage the Vega. Your thoughts?
I decided to save up a bunch of things and post them all right when I start so that I didn't suffer from "empty blog syndrome."
I decided to call my blog "The Prestigious Internet" because the internet is the opposite of prestigious. The barriers for entry are so low, you can publish anything. Hence my favorite site, Wikipedia.
