The Standard Model - summarized

In a most excellent overview of the Higgs(es?) news, The Economist manages the best concise summary of the Standard Model that I've read anywhere (emphases mine) ...

The Higgs boson: Gotcha! | The Economist:

... the Standard Model, the best explanation to date for how the universe works—except in the domain of gravity, which is governed by the general theory of relativity. The model comprises 17 particles. Of these, 12 are fermions such as quarks (which coalesce into neutrons and protons in atomic nuclei) and electrons (which whizz around those nuclei). They make up matter. A further four particles, known as gauge bosons, transmit forces and so allow fermions to interact: photons convey electromagnetism, which holds electrons in orbit around atoms; gluons link quarks into protons and neutrons via the strong nuclear force; W and Z bosons carry the weak nuclear force, which is responsible for certain types of radioactive decay. And then there is the Higgs.

The Higgs, though a boson (meaning it has a particular sort of value of a quantum-mechanical property known as spin), is not a gauge boson. Physicists need it not to transmit a force but to give mass to other particles. Two of the 16 others, the photon and the gluon, are massless. But without the Higgs, or something like it, there is no explanation of where the mass of the other particles comes from.

For fermions this is no big deal. The Standard Model’s rules would let mass be ascribed to them without further explanation. But the same trick does not work with bosons. In the absence of a Higgs, the rules of the Standard Model demand that bosons be massless. The W and Z are not. They are very heavy indeed, weighing almost as much as 100 protons. This makes the Higgs the keystone of the Standard Model...

I've read elsewhere that in the absence of the Higgs particles would zip around at the speed of light. Evidently, not so! The problem is rather with the W and Z bosons. That's quite different, but there's something about this summary that feels more authoritative.

I've pasted that text into Notational Velocity/SimpleNote so I have it in my extended memory.

There's more in the article ...

...  the model requires its 20 or so constants to be exactly what they are to an uncomfortable 32 decimal places. Insert different values and the upshot is nonsensical predictions, like phenomena occurring with a likelihood of more than 100%.

... One way to look beyond the Standard Model is to question the Higgs’s status as an elementary particle. According to an idea called technicolour, if it were instead made up of all-new kinds of quark held together by a new interaction, akin to but distinct from the strong force, the need for fine-tuning disappears.

Alternatively, the Higgs can maintain its elementary status, but gain siblings. This is a consequence of an idea called supersymmetry, or susy for short. Just as all the known particles of matter have antimatter versions in the Standard Model, in the world of susy every known boson, including the Higgs, has one or more fermion partners, and every known fermion has one or more associated bosons....

Google's Project Glass - it's not for the young

I've changed my mind about Project Glass. I thought it was proof that Brin's vast wealth had driven him mad, and that Google was doing a high speed version of Microsoft's trajectory.

Now I realize that there is a market.

No, not the models who must, by now, be demanding triple rates to appear in Google's career-ending ads.

No, not even Google's geeks, who must be frantically looking for new employment.

No, the market is old people. Geezers. People like me; or maybe me + 5-10 years.

We don't mind that Google Glass looks stupid -- we're ugly and we know it.

We don't mind that Google Glass makes us look like Borg -- we're already good with artificial hips, knees, lenses, bones, ears and more. Nature is overrated and wears out too soon.

We don't mind wearing glasses, we need them anyway.

We don't mind having something identifying people for us,  recording where we've been and what we've done, selling us things we don't need, and warning us of suspicious strangers and oncoming traffic. We are either going to die or get demented, and the way medicine is going the latter is more likely. We need a bionic brain; an ever present AI keeping us roughly on track and advertising cut-rate colonoscopy.

Google Glass is going to be very big. It just won't be very sexy.

Computing 2012: The End of all Empires

I grew up in a bipolar world.

Yes, the USSR vs. USA, but also the bipolar world of Microsoft and Apple. One was ruthless and ruled by corporate power, the other was a stylish tyranny.

Times changed. The USSR fell apart leaving a Russian mafia state ruled by a mobster, and the USA fell into a spiral of fear, wealth concentration, political corruption, and institutional failure. China grew wealthy, but turned into a fascist state run by oligarchs and mobsters. The EU has Greece and Italy and the second Great Depression. India, Brazil, everyone has problems, nobody is a secure Power. Now we live in a multipolar world.

Weirdly, the same thing has happened to the world of computing (now including phones). Microsoft's slow collapse is this week's Vanity Fair special. Google joined the Sith and all it got was dorkware, a human-free social network, and a profit-free phone. Post-IPO Facebook is rich and frail looking. Dell, HP, Motorola, RIM and Nokia are history.

Ahh, but what about Apple? Isn't Apple going from power to power -- even in the old Mac/Windows wars?

That's how it looks - to the press. Today. But I'm just coming off an epic 1 week fiasco involving OS X Lion and iCloud. It ended with me deciding to keep my primary machine on Snow Leopard and reverting my iPhone to iTunes sync after years of MobileMe sync. I'll try again when Mountain Lion is out.

Yes, few people will run into the problems I have had (arising at least in part from an obscure geeky bug with OS X/Unix vs Windows "line termination"). Many people, however, will run into some problems. My experience shows that many months after Apple's grandiose iCloud launch and insane MobileMe/iCloud migration, they still don't have troubleshooting tools and procedures or, amazingly, any way to delete your iCloud.com data. It's as though they thought they'd get everything right the first time -- perhaps because everyone associated with MobileMe was purged.

That's a hell of a miss for a corporation with billions in the bank and a fifteen year history of bungling online services.

Then there's the Apple ID/FairPlay/iCloud problems. My friends are struggling with these. Other friends can't figure out how to manage Ringtones on iTunes.

Perhaps most worrisome of all, Apple is providing mega-compensation packages to its corporate executives because, apparently, they must be retained. An unavoidable step with inevitable consequences. Bad consequences.

Apple doesn't look strong to me. It looks vulnerable.

Google, Apple, Microsoft, Facebook. None of them are serving me well. None of them are looking all that strong.

All the Empires are falling. My personal balancing act is becoming more complex all the time.

Traveling in Europe with an AT&T unlocked iPhone 3GS

Peter, a friend of mine, recently bought a used A&T 3GS from another friend. Since the phone's contract had passed AT&T approved a request for iTunes carrier-lock removal. So it was no longer a carrier-locked phone.

Peter took the phone to Europe and did very well with it there. I've not read many success stories so I'll pass on what he emailed...

Traveling to Europe the past several years I've taken along a very basic 2007 era unlocked Nokia GSM cell phone. It was always very easy to find small mobile phone stores. I would just walk in and buy a SIM card for that country for about €10 or so. It usually came with some calling time credit (easy to buy more credit at phone stores and some local shops), and the young guys staffing the stores were always helpful with setup assistance.

Buying an in-country SIM card allowed cheap calls and texts within in that country, and more expensive calls out of the country. Keeping in touch with friends and family back home can also be done very cheaply, if calls are made from the US to the European network mobile phone by Google phone from a computer. These calls from the US to a European mobile phone will cost about 10-15 cents per minute (calls from a computer in Europe using Google phone to a US land line cost less than 10 cents per minute).

[Peter then acquired the iPhone ...]

Setup of this clean iPhone with factory settings was easier than expected. I didn't have a SIM card in the US, but the setup was very simple using my home wifi network and following on-screen prompts. During the wifi setup I easily register the phone under my name using my Apple ID number, and synced my Gmail contact data (since I had previously added phone numbers to my Gmail contacts, I now had both email and phone contact data on the iPhone). I then hooked the phone up to my MacBook (OSX 10.5.8) and synced with iTunes. I enabled iCloud for contacts, email and Photo Stream and then bought a few apps. Very easy and intuitive.

In Rome a few days later near my apartment I found a small neighborhood mobile store for a major Italian carrier (TIM). As usual the techy guy working there spoke English. The process was simple - I showed him the iPhone (though he was a little surprised that I had an un-locked US iPhone), and asked to buy a SIM card (€20 with €15 voice and SMS credit plus free unlimited data for 1 month). He then had to register it with my passport info and do a little setup. The whole process took about 30 minutes, and with a little lag in activation time I was up and running with iPhone voice and data service in Rome within 1 hour.

Note: iPhone 3Gs uses a regular sized SIM card, iPhone 4 and 4s use micro SIMs, which may be harder to find in Europe (though it is possible to "cutdown" a regular SIM to micro size). Also you can buy a new basic unlocked GSM phone in Europe for about €30.

During my 2 week stay in Rome, the iPhone was very helpful - calling local friends, restaurant reservations, email, camera, using GPS and maps for locating sites and restaurants, and finding walking routes between sites... Especially helpful purchased apps included: Italian dictionary and verbs, Rome2Go, Rome Travel Guide - Lonely Planet (linked to GPS maps this was incredible useful), Contact Sync for Google Gmail, TripColor and Kayak Pro.

Moral of this story: When traveling in Europe, an un-locked iPhone is a fantastic asset. Next best would be any unlocked GSM smart phone or basic phone.

I'm amazed that a 20 euro card came with unlimited data!

Air Conditioning and obesity

I ate lunch at my favorite diner. Great food, but too much.

Sometimes I put enough aside; but not today. I ate the whole thing.

After lunch I left the cool hole-in-the-wall and walked into the great heat wave of 2012 (which will seem benign in 2022). I walked slowly back to the office, trying not to touch myself.

I blame it on the air conditioning. If China Restaurant hadn't been pleasantly cool, I know I'd have stopped sooner. 

Of course there would be other consequences of a world without air conditioning. I'm relatively slender, and I feel the heat. If I were heavier, the heat would be even more uncomfortable. Another incentive to weigh less.

So is modern air conditioning a factor in our losing battle with fat?

The question has been asked ... 

International Journal of Obesity - Putative contributors to the secular increase in obesity: exploring the roads less traveled June 2006

...The thermoneutral zone (TNZ) is the range of ambient temperature in which energy expenditure is not required for homeothermy. Exposure to ambient temperatures above or below the TNZ increases energy expenditure, which all other things being equal, decreases energy stores (i.e., fat). This effect was shown in short-term controlled human experiments 41, 42 and the decreases in adiposity were evident in controlled animal experiments; these effects are widely exploited in livestock husbandry, where selecting the environment to maximize weight gain is critical.43 Animal44 and human45 studies show that excursions above the TNZ markedly reduce food intake. Herman45 cited a consumer survey suggesting that after an air-conditioning breakdown, restaurant sales drop dramatically...

Suggestive data, but the relationship to "TNZ" sounds dubious. The authors should have described the findings as interesting correlations with some evidence of causation, then mentioned TNZ as one mechanism among many.

I couldn't find any more recent references.

Bicycle light donation - a selfish way to give

Today's commute was as good as it gets. Warm, sunny, not too hot yet. Bit of a breeze. Streets quiet. Cars considerate and happy. A good ride for daydreams of doing good stuff.

Until one of my daydreams runs into something practical. Something like a program to donate towards $10 easy to install semi-sealed high reliability blinking red bike lights.

I could bring $200 to an interested bike shop, put up a small poster, and see how it goes.

It's the kind of low energy donation I might actually do, and, best of all, it's anonymous. So no spam!

Even better, it's selfish. I worry a bit about getting run over, but I worry a lot more about running someone else over. More blinkies, fewer nightmares. A program like this ought to appeal to people who never bike, particularly elderly drivers with good reason to fear low visibility bicycles. Unlike helmets, which some cyclists dislike (not me), just about everyone likes blinkies [1].

My next thought was that someone has to have set something up like this. Of course they have, including in Minneapolis four days ago ...
These are great programs, but I didn't see one that involved distribution at local bicycle shops like Cycles for Change, Express Bike Shop, or my local favorites. So there's room for growth.

Anyone know of other programs like this?

[1] Except for the Apocalypse flavor of libertarian. In my searches I found someone complaining about the corrupting influence of bicycle light donations.
[2] It's in the lab. Machine vision/radar to identify pedestrians, animals, and bicycles and alert drivers.

After the decision - healthcare 2012

America's ObamaCare monster lurches forward.

It is hideous. Bits and pieces have fallen off, more will fall. It lost an elbow with the unexpected medicaid ruling.

Still, it moves. Lurches become steps. Trillions of dollars will build momentum. Plans made are being executed.

There will be ways to incent states to extend medicaid coverage. I am sure of that.

Some predict renewed GOP vigor and an enraged Tea Party.

I don't think so. I think that the American infotainment industry is now going to start talking about what the mandate really means. That mountain will become a molehill.

More importantly, the healthcare industry is going to pivot to making this concrete. Corporations hate uncertainty, and they hate reversing course. Romney will listen to them.

I would not be surprised if the ObamaCare hate dies as quickly as the 'defense of marriage' passion.

The monster is ours. We can rebuild him ...

Browsing the blog backlist - we need a new app

I follow about 150-250 active blogs including the "Core" blogs I read religiously.

It's a good reading list, far superior to the days when I read The Economist (RIP 2006, but a bit better lately) and the NYT. Still, there's something wrong.

The wrong bit is that there's rich material buried in the backlog of many of those blogs, and in blogs that no longer publish but are still online. Obviously some of that material is better than what I'm reading now.

We need a tool to surface that material and make it available. A blog backlist browser tool.

I'd like, for example, to give Reeder.app a set of 20 or so blogs and have a convenient way to read posts from years back. I've tried doing this in the "new" Google Reader, and it really doesn't work. 

Has anyone heard of anything like this?

Google's A.I. recognizes cats. Laugh while you can.

Google's brain module was trained on YouTube stills. From vast amounts of data, one image spontaneously emerged ...
Using large-scale brain simulations for machine learning and A.I. | Official Google Blog 
".. we developed a distributed computing infrastructure for training large-scale neural networks. Then, we took an artificial neural network and spread the computation across 16,000 of our CPU cores (in our data centers), and trained models with more than 1 billion connections.  
...  to our amusement, one of our artificial neurons learned to respond strongly to pictures of... cats ... it “discovered” what a cat looked like by itself from only unlabeled YouTube stills. That’s what we mean by self-taught learning... 
... Using this large-scale neural network, we also significantly improved the state of the art on a standard image classification test—in fact, we saw a 70 percent relative improvement in accuracy. We achieved that by taking advantage of the vast amounts of unlabeled data available on the web, and using it to augment a much more limited set of labeled data. This is something we’re really focused on—how to develop machine learning systems that scale well, so that we can take advantage of vast sets of unlabeled training data.... 
... working on scaling our systems to train even larger models. To give you a sense of what we mean by “larger”—while there’s no accepted way to compare artificial neural networks to biological brains, as a very rough comparison an adult human brain has around 100 trillion connections.... 
..  working with other groups within Google on applying this artificial neural network approach to other areas such as speech recognition and natural language modeling."
Hah, hah, a cat. That's so funny. Unless you're a mouse of course.

The mouse cortex has 14 million neurons and a maximum of 45K connections per neuron, so ballpark estimate, perhaps 300 billion connections (real estimates are probably known from the mouse connectome project but I couldn't find them). So in this first pass Google has less than 1% of a mouse connectome.

Assuming they double the connectome every two years, they should hit mouse scale in nine years, or around 2021. There's a good chance you and will still be around then.

I've long felt that once we had a "mouse-equivalent" connectome we could probably stop worrying about global warming, social security, meteor impacts, cheap bioweapons, and the Yellowstone super volcano.

Really, we're just mice writ large. That cat is looking hungry.

Incidentally, Google didn't use the politically incorrect two letter acronym in the blog post, but they put it, with periods (?), in the post title.

Best cities of North America - Chicago, New York, Montreal ... and Minneapolis

A report on bike share safety in NYC makes a number of safety recommendations and includes a graph of North America's best cities:


We see famous city names like Toronto, Chicago, San Francisco, Vancouver.

And then, way out on the right site of the best of the best ... Minneapolis (and, damn you, Portland to the right of us).

We rock.

Incidentally, the curve shows that as more people cycle the risk of death per cyclist falls (safety in numbers). Vancouver is everyone's target; Minneapolis and Portland need to study Vancouver's example.

My hunch for Minneapolis (and especially Saint Paul) is that the best way to reduce bicycle fatalities here is to enforce our neglected crosswalk law. Since that law primarily protect pedestrians that sounds a bit odd, but I think of this as falling under the 'broken windows' theory of bicycle and pedestrian safety. MSP drivers are gross violators of the crosswalk law and there's zero police enforcement. It's trivial to setup law enforcement sting operations, and it would make all drivers more conscious of their urban surroundings.

Wayback machine: My 2001 web site

The Wayback machine archived at least part of my old web site in 2001...

It was just a personal site, I think it is cool that a shade of it lives on, and of course for me it's fun to see the old page.

The menu on the right side included things of interest over a decade ago
  • A "starter" page for family physicians (used to teach net use)
  • FrontPage (97) esp: how to use
  • WiFi for home
  • MORE and GrandView - old beloved apps
  • My personal medical notes
  • Our Family News page (still active and updated)
  • Commuting bike page (still gets many hits, but it's archived)
  • Palm and "WWAN" - which back then was wireless wide area networking -- a bit before the BB, much less the iPhone
The site was dependent on a robust wysiwyg personal web site editor, and that technology died around 2001. On July 19, 2002, when my brother was lost, I wrote my first blog post. Almost ten years ago.

I archived the site in 2011, but the old links still work (they're simply not exposed) and I still search the site. If I ever find a replacement for FrontPage 97 I would at least like to resurrect the bicycling page in my Kateva.org domain. (When I retire I can go back to hosting pages under my "real name".)

The Minneapolis Friday Night Skate: 1998-2011

I wasn't at the very first Minneapolis Friday Night skate, but I remember Allan and Mike ...

Inline Skating (Rollerblading) Resource Center - Starting a Night Skate

... Mike Merriman and Allan Wright started the Minneapolis Friday Night Skate in 1998. More or less following the strategies above, the Minneapolis FNS was instantly successful with several dozen skaters the first evening. Participation rose dramatically with publication of a full article in a local paper, appearance by Allan on the local news station (the weatherman joined him on skates), and taping of the event by another television station. By the second year, the skate had reached levels of 150 skaters each time....

From the above page on starting a night skate you'll get to Zephyr Adventures, Allan still owns it and runs tours.

I think I joined in 1998 or 1999. I do remember the excitement; 100 skaters is a lot in Minneapolis. The skate varied over the years, but it usually looked something like this:

Screen shot 2012 06 16 at 10 09 54 PM

 In the early years there was a hint of anarchy to the skate. Even then we were Minnesotans and not kids besides -- so it was only mildly improper. 

Allan was dashing and charismatic, so it's not surprising that attendance declined after he moved on. Perhaps more importantly, inline skating popularity peaked in the mid 90s. By the early 2000s we were fortunate to get 30 skaters, but that was still an excellent number. 

Even in 2009, when family obligations kept me away from most of the skates, I loved it. The Stone Arch bridge, the spiral trail to Gold Medal Park, the seamy side of Hennepin, flying through Loring in the moonlight, waving to the crowds on Nicollet, watching the best skaters do leaps down the stairs, swooping down the hill and past the Nicollet Inn...

Things go away. By 2010 I'd stopped going, the numbers were too low. Bill F stuck it out through 2011, but sometimes he was the only skater. This year his FNS web site went offline.

One day, perhaps, inline skating will make a comeback, and maybe someone else will do a Friday Night Skate. Or perhaps it will pass into the history of Minneapolis, remembered by very few people. 

And this one blog post.

The evolution of spam: Nordstrom and mandatory spam acceptance

We've come a long way baby.

A year ago Nordstrom's began offering optional email receipts as "a convenient, environmentally friendly alternative to paper receipts."

Of course there are alway a few skeptics who doubted Nordstrom's integrity, but USA Today was reassuring

Retailers ditch paper and pen, use email for receipts - USATODAY.com

... no retailer serious about building a relationship with its customers would consider taking advantage of email access, said John Talbott, assistant director of Indiana University's Center for Education and Research in Retailing.

That's because for the retailer, the most significant benefit is being able to offer a service customers appreciate, he said. It isn't about cutting costs, he said, as less than 1% of a retailer's total revenue goes toward paper and ink for receipts.

Instead, the driving force is providing an option that makes the store a more appealing place to shop...

Yesterday Emily bought a shirt at Nordstrom's. The email receipt, she was told, was mandatory. No, of course there'd be no spam. She doesn't have a spam account, so she gave them her gmail account.

She got her first Nordstrom spam a few hours later. I'll show her how to use filters later today.

Not to worry though, paper receipts are not long for this world. Soon we'll be buying things with our phones. No spam there, since of course there's no tie between our phone's unique identifier and our email and phone number.

Median net worth stasis: health and demographics?

Salmon of the Trinity [1] notes that Median net worth has actually been static for about 30 years. So we can either fund social security, or learn to live with elderly beggars, or invest in Soylent Green.

It's a fascinating result; seemingly consistent with other studies on long term wage stagnation. I'm looking forward to more discussion, including ...
  1. What is the effect of demographics, in particular what is the mean age of the median net worth over the past 30 years? We know our population is aging, and we know net worth increases far faster in one's 20s than in one's forties.
  2. What is the relationship to savings? (Presumably, other than "housing", it means we're not saving - see "social security")
  3. How much of this is because of health care and education costs? How much more expensive is it to raise a child in 2010 than it 1980?
  4. Is there an "occult inflation" contributor?
  5. Is it coincidental that this stasis corresponds with the widespread dissemination of programmable technologies?

Why bicyclists run red lights

France Grants Cyclists the Right to Run Red Lights. Basically, cyclists are to treat a red light as a one-way stop sign.

There are moves to do something similar in several states, but it will probably be a few years before it's accepted in Minnesota. In the meantime running a red light on a bicycle is theoretically illegal here. (There's an exception for "long lights" where it's obvious that the bicycle isn't triggering a light sensor.)

Theoretically, because I can't find any Google hits on anyone actually getting ticketed for it. Still, I think bicycle tickets come with auto license points, and that's a big deal. So I'd rather not get a ticket.

Which is a bit of a shame, because there are really good reasons for bicyclists to treat a red light as a one-way stop sign.

From a bicyclist's point of view, the biggest road risks are distracted drivers, incompetent drivers, and angry drivers. These drivers are dangerous everywhere, but they're particularly dangerous at intersections where they can, for example, make a right turn into a bike while chatting on the phone. At an intersection, a bicycle is stuck in bad company.

Going through the red light though, that gets us clear of the distracted and the angry. It also makes us quite visible to cars that will catch up from behind -- they take notice of lawbreakers. We love to be seen.

Of course such insubordination makes angry drivers angry -- but they'd find a way to be angry at bicycles anyway. At least they can be righteously angry, which is a warm and fuzzy kind of angry that may make them less dangerous to bicyclists, spouses, and small animals.

I'm a boringly law abiding geezer, but I'm staring to think the lifesaving advantages of lawbreaking may offset the minimal risk of a ticket...
