When you can measure what you are speaking about, and express it in numbers,
you know something about it;
but when you cannot measure it, when you cannot express it in numbers,
your knowledge is of a meager and unsatisfactory kind.
It may be the beginning of knowledge, but you have scarcely, in your thoughts,
advanced to the stage of Science.

—William Thomson (aka Lord Kelvin).

"It left me more confused, but in a good way."—unsolicited comment on the Hitchhiker's Guide, from Ben Gillen (UCSD, economics).

Roko Aliprantis and I finally released the new and improved third and final edition of Infinite Dimensional Analysis: A Hitchhiker's Guide, published by Springer (ISBN 3-540-29586-0). Now available in a paperback people's edition. There is a very flattering review of the first edition on Amazon.com. The reviewer is neither on my payroll nor a co-author.

Or be the first on your block to own a copy of Fixed Point Theorems with Applications to Economics and Game Theory, published by Cambridge University Press.


Errata

My mentor Ket Richter convinced me that I ought to put the errata for these books on the web.

Come back later for updated errata. I'm sure there will be some.


Recommended Recent Reading

These are a few of the books that I have enjoyed recently.

Mathematics

Classical Descriptive Set Theory, by Alexander Kechris. Springer-Verlag: 1995.
More than you ever want to know about Borel sets and their unruly relatives.
Nonsmooth Analysis and Control Theory, by F.H. Clarke, Yu.S. Ledyaev, R.J. Stern, and P.R. Wolenski: Springer-Verlag, 1998.
First order conditions and inverse function theorems, all without differentiability. Cool.
Linear Semi-Infinite Optimization, by M. A. Goberna and M. A. López. Wiley, 1998.
A semi-infinite linear program has either finitely many constraints or finitely many variables, which still covers a lot of territory.
Comparison Methods for Stochastic Models and Risks, by Alfred Müller and Dietrich Stoyan. Wiley, 2002.
Almost everything I know about stochastic dominance relations and a lot more. A must read.

Other nonfiction

The Perfect Storm: A True Story of Men Against the Sea, by Sebastian Junger. W. W. Norton & Co.: 1997.
A fascinating account of the economics of swordfishing and the physiology of drowning, among other things.
Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation, by Lynne Truss. Profile Books, London, 2003.
A discussion of the history of, and the rules for, proper British punctuation. The title refers to a panda joke. It also discusses American punctuation in passing; but it's not really about the rules per se; it's really a feel-good book for those who care about punctuation. Its message is: it's okay to be outraged when punctuation is misused. Nevertheless, The Economist has pointed out that they would write the subtitle as The Zero-Tolerance Approach to Punctuation. Still, it's full of delightful examples, such as this excerpt from a letter from George Bernard Shaw to T. E. Lawrence (of Arabia), in reference to The Seven Pillars of Wisdom: "You practically do not use semicolons at all. This is a symptom of mental defectiveness, probably induced by camp life."
America Walks into a Bar, by Christine Sismondo. Oxford University Press, 2011.
A wonderfully written compendium of quirky facts and interpretations concerning the role of taverns and saloons and bars in the history of the United States. For instance: "At the root of the Salem hysteria and tragedy, then, was a long-standing dispute between urban merchants and rural farmers. This entailed debates over the tax structure and the redistribution of income and, finally, political and religious self-determination ..." (p. 33) Or did you know that George Washington treated the 310 registered voters in his 1758 run for the House of Burgesses to 47 gallons of beer, 34 gallons of wine, two gallons of cider, 3 1/2 pints of brandy, and 70 gallons of rum punch (p. 45). And it was not until 1971 that the Supreme Court in Sail'er Inn v Kirby recognized the right of women to tend bar in California (p. 244). And there's so much more.

Fiction

Cryptonomicon, by Neal Stephenson. Avon Books, 1999.
Convergent parallel stories of paranoia, code breaking, and the dangers of doing business with venture capitalists. The language, while frequently poetic, is fairly crude, so I do not recommend this for children.
Carter Beats the Devil, by Glen David Gold. Hyperion, 2001.
Did the magician Carter the Great murder President Warren Gamaliel Harding? (If not, why not?) Why doesn't every schoolchild know about Philo Farnsworth? A delightful tale based on historical figures. (Fiction ?)
Special Topics in Calamity Physics, by Marisha Pessl. Viking, New York, 2006.
Blue van Meer was raised by her father, a peripatetic academic economist and political scientist, to be the perfect graduate student by the time she was a senior in high school. Her account of her senior year is maddeningly detailed and footnoted, but the last one hundred fifty pages are a wicked roller coaster ride.
Night Film: A Novel, by Marisha Pessl. Random House, New York, 2013.
Marisha Pessl's second novel is a terrific Gothic mystery. Clear your calendar before starting—you won't want to be interrrupted.

Los Angeles

It is hard for someone from The East or The Bay Area, or even La Cañada Flintridge, to understand this, but I love L.A. That is why I live in Los Angeles, and not Pasadena. Not that I have anything against Pasadena, it is quite charming.

A look at some facts

Contrary to what you might think, L.A. is not a crime ridden slum. That is a rumor we perpetuate to keep out the riffraff.




Origins

In 1781 the governor of Alta California created a new settlement, El Pueblo de Nuestra Señora la Reina de Los Angeles del Rio Porciúncula, on the plain below the mission of San Gabriel. Land in the new settlement was awarded to a multiethnic group of veterans of the war for independence from Spain. Here is a little more on the early history. There is more at Wikipedia.

My neighborhood

I live on what used to be an oil field lying on the northeast edge of the geological formation that includes the La Brea Tar Pits. During the summer, tar oozes to the surface on the sidewalk next door, with methane bubbling through it. Unwary small children and old people then track this tar all over the neighborhood. I am told the city has included the area in a methane hazard district, but Caltech geologists assure me that the danger of an explosion is nil unless you have an unventilated basement. (An unheard of amenity in Southern California residences.) Update: The tar seepage seems to have stopped now.

You get a nice aerial view of my block in one of the early scenes of Unlawful Entry. (My house is the one without a pool.) The area is old by the standards of L.A., with most of the houses built between 1922 and 1924. Here is a sequence of maps showing where I live. (In 1995, this was really cool.)

My neighborhood comprises two-block lengths of three streets, surrounded by minor arteries and a private golf course, of which I am not a member. It is a real neighborhood, where I walk to the market, bank, restaurants, and movies; we have Fourth of July block parties; and I know my neighbors. (I know many more of my neighbors than when I lived in either Minneapolis or St. Paul. On my block live Al, Alex, Anne, Betty, Bill, Bobby, Carolyn, Chris, Connie, David, Elizabeth, Ellen, Frances, Greg, Henry, Joe, John, Joyce, Julie, Keith, Linda, Liz, Mariko, Mark, Melissa, Mike, Pat, Paul, Percival, Philip, Rob, Robert, Rodolfo, Sandy, Sloan, Steve, Susan, Susie, and Wayne, among others, not including children.) On Halloween, the few people who have moved out of the neighborhood to nearby areas return to go trick or treating in their old haunts. I have lived in my house for over twenty-five years now, so I am no longer a newcomer, but my neighbors for two houses on either side are still the same as when I moved in. Some people live in the houses their parents owned and in which they grew up. (One of the side effects of 1978's Proposition 13 is that it increases the cost of moving by eliminating your artificially low property tax valuations if you move.)

Some of my neighbors and former neighbors work in The Industry, that is, they produce, write, direct, litigate, and act in movies and TV, and generally corrupt the public morals. You would recognize some of them on sight and have probably seen the work of many more. (Out of respect for their privacy, I won't mention names, but at least ten are listed on this site.) Other former and current neighbors are Real Americans, such as firefighters, sheriff's deputies, ministers, accountants, Boy Scout leaders, small factory owners, court reporters, veterinarians, university professors, engineers, hairdressers, librarians, limo drivers, massage therapists, attorneys, physicians, public and private schoolteachers, psychotherapists, and slackers. A dwindling number are retirees.

My son graduated North Hollywood High School, a public school in the Los Angeles Unified School District and subsequently graduated Wesleyan University. Another of his former schools, Walter Reed Middle School, was used for the exterior shots of the middle school for the TV series 7th Heaven. Seems like everyone wants to be in pictures. On another note, the school was also used as a stand-in for the Walter Reed Medical Center in the video backdrop of John McCain's acceptance speech at the 2008 Republican National Convention.

Other local attractions

Kim Basinger's house in L.A. Confidential is just around the corner, but sadly she doesn't really live there. The house used for the exteriors of Happy Days is six doors up the street, in case you ever wondered why there are palm trees in Milwaukee. I take my MINI to our trusty neighborhood mechanics at Pinky's Automotive. Close by are The Brothers Collateral (pawnbrokers to the stars), the Iglesia de Dios Camino de Santidad, and the Spotlight Tattoo Parlor. Paramount Studio's famous Melrose Gate (remember Sunset Boulevard, the movie) is eight blocks away. Larchmont Village, a local shopping block with diagonal parking, a barber shop, and a five and dime, is an easy six block walk away. Despite Larchmont's small-town feel, I've occasionally found myself in a restaurant seated next to a celebrity, such as Ben Stiller, Tony Shalhoub, or William Peterson. One of my biggest thrills was running into the then little-known Heather Graham at the ice cream shop while she was (briefly) on Twin Peaks (1991).

Most mornings on my way to the office I stop off at Caffé Etc. Hollywood for a small latté. The caffé has recently been the subject of a reality video.

On Sunday mornings, the Hollywood Farmers' Market meets about a mile up the street. It features excellent produce, including the best Seascape and Gaviota strawberries, wonderful haricots verts, fantastic sourdough bread from Jack Bezian, marvelous fish from Marilyn of J & P West Coast Seafood, and live music ranging from Hisao Shinagawa to the Fair Market Band to the jazz trio of Carl Tassi, Cengiz Yaltkaya, and Morrow Fleet. We almost always meet some neighbor shopping there, and occasionally another Caltech faculty member who has made the trek from Pasadena or somewhere nearer.

Incidentally, I am aware of the controversy over eating fish, see, for instance, this piece in The Economist.

The Los Angeles County Museum of Art and the Petersen Automotive Museum are about three miles away. The 18,000-seat Hollywood Bowl, the nation's largest natural amphitheater, is two and a half miles away.

Urban wildlife

Griffith Park is the nation's largest municipal park and urban wilderness area. It comprises 4100 acres of steep hillsides covered with sage and manzanita, springs, and a natural creek. For comparison, The Regent's Park in London is 410 acres, New York City's Central Park covers 843 acres, and the Bois de Boulogne in Paris covers 2137 acres (865 hectares). The park is about two miles away at its nearest point, though the good hiking is a bit further.

Real live rattlesnakes and coyotes live there, and according to the Times of April 29, 2004, a mountain lion was living there. (The California Department of Fish and Game reports that mountain lions have killed two people in Southern California since 1910.) The Beverly Press reported on April 24, 2014, (p. 3) that a lion, named P 22, has been living in the park since 2012. It had been treated the previous month for the effects of rat poison. It is hypothesized that it had eaten a coyote that had been dining on poisoned rodents.

You don't have to go to Griffith Park to get close to wildlife. Once, I was walking home from dinner at Xiomara around 8:00 p.m. and saw a family of four raccoons crossing the four lanes of Melrose Avenue. They then proceeded up the street, scurrying one at a time from under one parked car to another. Another time I almost tripped over a coyote in the parking lot of Yamashiro, a Hollywood restaurant. I have had a heron land in my backyard, an owl in my neighbor's yard, and I have been buzzed by a duck (teal) that landed in my neighbor's front yard. This happened after my other neighbor's cat, Vlad, tried to sneak up behind him. I have walked past a red-tailed hawk perched on a parked car three doors down from my house, and more recently had one walking around my front lawn. And of course my back yard is home to squirrels, tree rats, tree frogs, and lizards, and is visited by the occasional wandering opossum. One night, my black Labrador proudly retrieved a juvenile opossum from the back yard and brought it to me in the den. With a little coaxing, she dropped it on the floor and I took it out to the front yard. Half an hour later it had wandered off.

Coyotes had been sighted in the neighborhood a few years ago, which caused much concern among owners of small pets. The city responded with a meeting on coyote encounters.

One downside of this abundance of urban wildlife is noise. The springs of '08 and '09 were alive with the sounds of frogs at all hours of the day and night. The summer of '08 brought a pair (or more) of urban mockingbirds who never seemed to sleep. They learned to imitate my alarm clock as well as several different models of car alarms. They love to practice these calls from about 1:00 a.m. to 4:30 a.m.

The rest of the city

Here are some Angelenos on the street.

Some of us pay extra for street lighting.

But life in L.A. can be tough on some people. Here is our former mayor, Richard Riordan.

Disclaimer: The city is constantly changing and I don't have time to keep this page in sync with it. The information here was valid when I wrote it, but the world may have changed since then.


I am not Simon Wilkie

My former colleague Simon Wilkie is an internationally recognized scholar with extensive experience in the communications industry, and is the Chairman of the Department of Economics at the University of Southern California. Nevertheless, people sometimes used to confuse us, so here are our old official Caltech ID photos. As you can see, we look nothing alike.

Genealogy

Through the internet I have been contacted by three fourth cousins I never knew I had. (By the way, you have changed your email addresses-please send me your new ones.) The 2000 Census lists 2180 people in the U.S. population with the surname "Border" (which is the 12,900th most common on their list). One of my great-great-great-great-grandfathers on my father's side, the family namesake, was Sebald Bäder, also known as Border, a gunsmith from the Palatine who settled in Fredericksburg, Maryland around 1760. He was married to Regina, maiden name unknown. Another great-great-great-great-grandfather (on my mother's side), George Lohr, probably came to Baltimore from the Palatine in 1750 or 1754 on a ship from Rotterdam. (My sister has found three manifests with George Lohr, two in 1750, one in 1754. One of my long lost cousins informs me that he made two trips.) (The Census Bureau reports 6506 people named Lohr, ranking 4962.) Another pair of great-great-great-great-grandparents on my mother's side comprised Michael Wolford (10,738, rank: 3096) and Anna Maria Baker (413,351, rank: 38) , who were also living in Pennsylvania before the revolution. Other, less distant, family names that I know include Custer (but pronounced with a long u) (10,684, rank: 3110), Stambach (184, rank: 92,601), and Lape (2407, rank: 11,910).
