Folks:

I’ve drafted a review of the Infiniti M35 sedan.  I would appreciate comments/corrections.

Thanks,

Philip

The A380 arrived in the U.S. today.  The plane can carry 81,890 gallons of fuel and flies 8000 nautical miles, i.e., it burns approximately 10 gallons of fuel per nautical mile or 9 gallons per statute mile.  The plane can seat 850 people if configured as an all-economy ship, so the mpg per person is approximately 95 (assuming the plane is fully loaded, which most planes seem to be these days).   The Prius gets around 45 mpg in real-world driving and, though it can seat 5, is typically occupied by one person.

[I once saw an analysis of overall per-passenger-mile transportation cost, including capital investment and labor costs.  The Boeing 747 was the cheapest form of transportation, period.]

I’m attending a meeting at the University of Maryland.  Some of its top bureaucrats reminded us that Maryland was ranked 18th in the world in social sciences and 15th in engineering.  That’s pretty good for a school that gives bright Maryland kids a free ride through their honors program (they even pay for textbooks).

A bigger difference between U. Maryland and schools in Massachusetts is the connection to government.  The campus is punctuated by U.S. military personnel in uniform.  The meeting here is attended by ministers of telecom from diverse countries in Africa as well as officials from the U.S. Department of State and US AID.  A U. Maryland graduate will learn about opportunities in government that would never occur to an undergraduate at a school outside of the Washington, D.C. area.

The New Yorker’s March 12 issue carries an article entitled “The Denialists–AIDS mavericks and the damage they do” about folks, mostly in Africa, who say that HIV does not cause AIDS and is in fact basically harmless.  The article tries to cover all sides of the issue, but leaves out what to me is the most powerful evidence that HIV is something you don’t want to have in your system.

If you know that HIV is harmless and most people think HIV is deadly, that opens up an opportunity to make near-infinite money.  You simply write life insurance policies for the HIV-positive, a group that other insurers shun.  If an African politician says “HIV doesn’t cause AIDS”, all you need to ask is “How come you’re not investing in life insurance for HIV-positive folks?”

I’ve just posted two jobs:

• aviation summer internship
• helicopter instructor (for someone with a CS background who has decided there is more to life than sitting at a desk)

I would appreciate comments, referrals, etc.

From the March 9, 2007 Tech. The story is about a Chinese kid, Jian Li, who has asked the U.S. Department of Education to review Princeton’s race-based admissions system. The fun part is from 1998, when Henry Park, a top student from a top prep school, applied to a bunch of high-priced colleges, including MIT, and was rejected. The MIT Dean of Admissions, Marilee Jones, said, never having met the guy, “It’s possible that Henry Park looked like a thousand other Korean kids… yet another textureless math grind.”

Conversation turned the other day to Tony Packo’s, the Hungarian restaurant in Toledo, Ohio that Klinger talked about on the TV show MASH.  I only finished about half of my meal there because there were so many corpulent people at nearby tables.

This led to a new idea for a weight loss service:  rent out obese people to those who wish to lose weight.  Every time you sit down for a meal, your new 300 lb. friends will join you at the table.  It won’t be a struggle to leave something on your plate.

One of the funny parts of Founders at Work is Nathan Myhrvold, paid to be the smartest guy at Microsoft, saying “Search is not a business” to the founders of Excite in 1995 (page 68).  Joe Kraus goes on to say “By 1997, everybody was diversifying into portal stragies, because nobody knew how to make money from search.  Search was viewed as the traffic director to other more profitable businesses…”

More wisdom from Kraus:

I see way too many people give up in the startup world.  … Recruiting is a classic example.  I don’t even hear the first “no” that somebody says. … It’s hard to identify talent, but great people don’t look for jobs, great people are sold on jobs.  And if they’re sold they’re going to say no at first.  You have to win them over.

The exciting social life of a helicopter instructor… clearing off the desk on a Saturday night.  Before I throw out the February 2007 Rotor and Wing magazine, I thought it worth relating the results of an experiment by a police department SWAT team.  They loaded a bunch of sharpshooters and their rifles into a helicopter, went up, and tried to shoot some person-sized (stationary) paper targets on the ground.  Unlike in the movies, the guys in the helicopter were not able to hit anything on the ground.  Meanwhile, despite wearing earplugs and a helmet, the pilot was getting a terrible headache from the noise of the sniper rifle firing.  They do shoot goats from helicopters in the Galapagos, but somehow it doesn’t work here.  The author concluded that nothing less than an Apache would suffice for the police to use against perpetrators…

Disagreeing with Carnegie on the virtue of leisure, Kirby Chambliss, champion air racer, explains how he answers those who ask what it costs to race:  Everything.  “It takes all you have,” says Kirby.  “If you’re trying to be the best in the world at something, no matter what it is, you need to dedicate your life to it.  You can be sure your competitors will.”

Is it dangerous to fly under bridges going 200 mph?  “You live and learn, or you die and you don’t. … You may forget the danger, but every few months, one of your buddies reminds you by killing himself.”
