Frederick Taylor -- Scientific Manager

Frederick Taylor was an engineer during the Industrial Revolution in the US working 1883-1906.  He was a practical man who wanted to make factory better by making it more efficient --often making it more efficient made the work ergonomically easier.

For example, he did work on the so-called science of shovelling. He determined that a worker should shovel 21 lb per shovelful so that he could go the longest time. He also coached workers to use their body not their arms to lift. Today we know that sore backs are a big chronic problem, and that sore arms are less serious.

Taylor wrote a large book called The Principles of Scientific Management, which happily is free on Kindle and on Google books. Scientific management is not the management of science, but rather the use of experiments to improve productivity.

Taylor's work is hard to summarize, but three principles:



  • Inefficiency hurts America
  • Systematic management helps efficiency, not hiring for extraordinarily good workers
  • Management is a science that has laws, rules and principles.


  • Some of what Taylor advocates might be called worker training today. That is, if we show people how to shovel, then they shovel better. In the 1890's workers were assumed to know how to do their work, and the bosses often did not.

    When I was in business school I admired the idea that studying the work at hand could make accomplishing it easier. I particularly liked taking a detailed approach to relatively simple workplace problems.

    Reading Taylor today,  social issues problems and class distinction are on every page. Taylor regarded himself as progressive in his day, and he tries to give what he says as a reasonable view. The country, and actually the industrializing world of the time, were all grappling with these issues. It may have taken another fifty years before some resolution is achieved.

    More: Taylor writes about "soldiering" which means workers who slow their work-pace deliberately to get paid more or so that the employer needs to hire more workers. Maybe  we'd call that goldbricking or featherbedding today. Taylor understood that paying by piece-work only helped so much. He thought his system led to greater productivity, and the ability to pay higher wages which would motivate the workers to have a better attitude and work harder.

    Even More: This an excellent web page on early management theorists.

    Wine Label Art

    Cool bottle from Honey Moon Winery in Bellingham, Washington.
    This is a bottle of mead, which is made from honey.

    I came across a great collection of labels in Coolist.

    Wine labels are probably the best commercial art out there.
























    This label was banned in Alabama as too revealing. It is
    also pretty weird with the flying bicycle.

    Fertilizer from the Air and Its Invention

    Carl Bosch
    Carl Bosch, who was a chemist for BASF, and developed a practical industrial process for making ammonia from the air. It is called the most important chemical process ever discovered making fertilizer that allows farmer to feed so many people. It is said that half of the nitrogen in the human body has been synthesized from the air.

    Bosch was assigned to the project by his bosses, who bought rights to the invention of Fritz Haber. Haber was a Professor at Karlsruhe, when he developed a high pressure process to fix nitrogen using a ruthinium catalyst in 1907.

    Haber had a number of collaborators including Le Rossignol for the pressure equipment, Nerst for the thermodynamics, and Ostwald for prior art in catalyst selection.

    The point here is that Haber had a network, and Haber and his bosses at BASF were plugged into it. Networks and the interfaces between organizations continue to be important in transmitting ideas. The isolated genius is not a very important phenomenon in science.

    Didn't Fritz Haber have cool glasses? Oh, that is
    his lab set up in the hood.
    A Bosch Reactor
    Bosch's project was the biggest chemical engineering plant at the time. It is an early example of Big Science. Significant technical projects today are increasing efforts of hundreds of people. Bosch's project was fast. He had the plant up in just five year making 7 million kg of ammonia a year. Today BASF makes 110 times that much in Germany.  Bosch got that plant up in 4-5 years. He was motivated by the threat of a British naval blockade, but also things just moved faster back then.

    Heimliched at McDonalds



    I was at McDonalds killing time before a business meeting on the road. Just behind me woman started choking, and the women at the table were wondering what to do, then they said loudly, "She's Choking!" A guy the next table got up, and grabbed the woman and did the Heimlich maneuver on her. I was wondering what to do, but I didn't do anything.

    The woman was chubby, and that made it hard to get good leverage, but the guy kept doing it. The women turned blue in the lips, and kept trying to gasp for air. They just kept trying to Heimlich her, every minute or so.

    The McDonald's workers noticed, and soon the store manager was there. He was pretty tall, and he tried to Heimlich her too. He was fast; he just kept Heimliching over and over. He pulled her up in the air when he pulled, and hardly let her down to the ground in-between Heimlichs he was pulling so hard and so fast.

    The poor lady looked really desperate, and tired and scared and blue. She fainted or maybe she fell. The manager picked her up and kept trying. She had foam at her month since she couldn't swallow either.

    The woman's friend (her 16 year old niece as it turns out) got on the phone to 911, and was trying to work the 911 operators question tree -- no she is not unconscious; no she can't talk; she was eating chicken nuggets and french fries...

    The second time she fell; it was all the way to the ground, and she laid back. This time her head was right next to me since she fell across the aisle. She lost strength in her legs or she fainted, and the people couldn't hold her up. She looked just terrible.

    In 2-3 minutes, a fire truck is coming down the street, and a guy is hanging out of the doorway waving for the firefighters to come in. The fire captain wasn't tall, but he was beefy, and he stopped the restaurant manager. Then he said something to the woman's friends, and started Heimliching himself. He was slower,  smoother and more rhythmic than the others.

    I don't know if the woman was breathing, but she much have been getting some air. Soon they stretched her on the ground, and they were giving her an abdominal message -- something like a Heimlich maneuver but lying down. It looked like a heart message, but actually it was in the abdomen not the chest.

    The color in the woman's face got better, and I exited the restaurant.

    After watching all this, I felt terrible. This poor lady had been thought this terrible ordeal -- frightened and choking. I felt worn out from just being there.

    Lion Droppings (Issues with Mac OS 10.7)

    Everyone knows that Apple issued a new OS, and it is the biggest re-write in years. It brings a more iPad feel to the desktop, and geeks say that it brings far more security. It drops support for PowerPC code; that is applications native to OS 8 or OS 9.


    This means that lots of specialty applications don't work.  I deleted about eight old programs including a screen capture program,  and a font manager. Notably the driver for my ancient Canon scanner no longer works. Looks like I am going to start photographing documents.

    Most important to me is accounting software that my wife uses in her business -- AccountEdge 2004. This no longer runs in Lion, and it needs to upgrade to AccountEdge 2011 for $300.  Jenny's business is a lean operation, and $300 is a lot of money.   The main issue is that she uses a few features all year, and then we need to make statements for income taxes at the end of the year. Now $300 is less than an accountant would cost, so I suppose that it is cheaper. I guess a dual boot system  is the way to go.

    News reports are that Flash is not supported in Lion, but I can say that it is. It runs on my computer fine.


    The so-called "iPad" feel of Lion is overblown to me. Notably the window dragging gesture has been reversed on the Mac to make it more like the iPad. This seemed weird at first, but it actually is more natural -- more like push a piece of paper across a desk. On the other hand, I expect I will always be confusing the direction with that on my Windows PC. There are some changes in the menus, and indicator bars. There is a default full screen option, that gets rid of the desktop clutter. Overall look and feel is not that different.

    Etsy has Bugs

    DW Jenny makes her living selling stuff and lately patterns on Etsy, the website for crafters. Etsy has attracted mockers in the form of Regretsy, which is adolescent but occasionally funny.

    Etsy had been growing rapidly with sales on pace for $450 million for 2011 over the $314 million in 2010.

    Etsy Sales; Note the 2011 sales are in
    the original caption.
    Our issue with Etsy is a bug in their software. Most sellers forward their customers to Paypal automatically to pay. Paypal extracts several percent commission, but usually this goes flawlessly. Yesterday, Etsy sent incorrect email addresses to my wife's customer -- creating confused and angry customers.

    I am posting about this since there have been almost nothing on-line about this bug. (We did find a similar issue on the Etsy bulletin board.) It looks like Etsy restored some old data; presumably because the newer data got corrupted.  Jenny had her old defunct email address replace her current one, and Paypal posted the funds to the wrong account.

    Etsy seems to have had a hacker attack, a virus or perhaps just bad luck with hard drives.

    Anyway. Jenny lost a $60 sale, and had a customer leave multiple bad feedback. All for a software bug at the host website.

    Etsy is so understaffed that it does not try to answer complaints one-at-a-time. Jenny got a form-letter back when she contacted Etsy.

    I suppose it could be worse. The customer will keep her money, and no harm was done.

    If anyone has had similar issue, please leave a comment. Thanks.

    iPod Nano Woes (5th Generation)

    My iPod died, and I found no helpful posts on-line about fixing it.

     Depth-of-Processing fans might remember the multiple posts about my woes with the ill-fated iPod Shuffle (3rd Generation,) and how Apple eventually mailed me a iPod nano (4th Gen) to resolve the problem, which lasted a short while and then died. I work my iPods pretty hard.

    Well my current iPod Nano (5th Gen) is seemly irretrievably wrecked after about two years of faithful service. It randomly pauses and/or produces buzzing noise at the pitch of the last note it made. Also the click-wheel works slowly -- like the processor is busy. I tried the usual stuff like resetting (hold menu and center,) diagnostic mode (reset, but quickly hold menu and rewind,) and restoring using iTunes -- and all were no help. 

    There is very little on the internet about this problem, which suggests it must be a pretty rare problem.  It sounds like hardware, and I don't want to try to open up the iPod to fix it.  

    My solution is to get a new one. Off to Best Buy.

    Arctic Tern

    My new hero is a 100 gram bird, the Arctic Tern. We  were planning a trip in the fall to a point on Lake Erie in Ontario where birds hunker down before flying across the lake, when I found out about the world champion and utterly amazing bird that flies from the arctic to the antarctic, and back each year.

    It flies 22,000 miles each season, from Greenland to Antartica and back! Over 44,000 miles because they don't fly in a straight line; often going 10% too far to catch the wind. The live for thirty years flying 1,330,000 miles in a lifetime, which is just mindlessly too much.

    Arctic Terns don't like water, and they don't like land much either. They prefer to catch insects in the air, and they stay aloft. They mostly eat fish like other terns.

    Baby Terns fly too much too. One three month old tern was found in Melbourne, over 14000 miles from Britain where it was born.

    Stock Market Whammy

    Economic Crisis!
    I am recycling my favorite picture from the
    2008 recession. Gotta luv this picture of Secretary
    Paulson.
    I was alarmed like everyone else by the pounding on the stock market Thursday. Everyone was wondering how Congress caused America to lose $930 billion dollars in the last week. That is the $13 trillion value of the stock market times the 7.2% that the Standard and Poors 500 lost in the last week.

    Here are the losses in various stock indexes in the last week, Friday to Friday.


    -5.8     Dow (US)
    -8.1     Nasdaq (US)
    -12.9   DAX (Germany)
    -5.4     Nikkei (Japan)
    -7.2     Standard and Poors 500 (US)
    -7.9     DJ Wilshire 5000 (US)
    -6.7     Hang Seng (China)
    -9.8     FTSE 100 (Britain)

    As bad as things are in the US, big US stocks held up best. The Dow only lost 5.8%.

    Rock solid and fiscally-sound Germany took the biggest pounding (-12.9%) -- why?  Who really knows, but it seems the bailout for Greece, Italy and Spain are really the worry.

    Strange as it seems the Tea Partyers are not to blame.

    The Power of Experiment and the Limits of Logic

    I am reading a book by James Gleick, called The Information" A History, a Theory, a Flood.  For a book about information, it spends  a lot of time on the limitations of information and reasoning. For example, we know that mathematical proofs cannot prove everything that is true to be true. Mathematician Kurt Goedel, showed that mathematically in 1931.  This is just like computer genius Turning showing that there were some problems a computer could not solve.  
    This is surprising because science and its logical methods have worked so well in advancing technology for  the last 130 years. 

    On the other hand, application of logic to religious problems seems to lead to mass murder like when Anders Behring Breivik killed 88 Norwegian kids because their parents did not agree with his notions of racial purity. Breivik had 1500 pages of seemingly logical arguments for so-called Christian terrorism and racial purity. 
    The powerful thing about science is not the theory, but rather the experiments. It is hard to run experiments in religion or philosophy.  In science we can test whether our reasoning is true; in morality, or epistemology, or theology, experiments are hard to come by. 

    Consider evolution, where science is validated by experiment, and creationist bible interpretations are not. Many believers also believe in evolution because of the evidence, but many do not because of Faith. I have nothing bad to say about Faith, because as mentioned above logic can only get us part way. 

    On the other hand, building a castle of logic on top of a faith-oriented belief can get twisted around. I am reminded of "Let the children come to me ... for to such as these belong the kingdom of God." [Matt 19:14]  Implying that getting too complicated isn't the way to the kingdom of God.
