Thinking Outside the Boat
April 19, 2013
Scientists work with
theories all the time. We're constantly framing our own theories, and we do this carefully, since we're ever mindful that they will be
reviewed by other scientists. We never trust our theories unless they are backed by considerable evidence, usually by
experiment. That's why we always chuckle at
business theories, which are usually
hand-waving cloaked in a
three-piece suit.
One business theory, which I hope has passed out of favor, is the idea that all activities can be reduced to a
process. Even a marginal
employee can do great things if he or she would just follow the process. Activities amenable to a process are not just
assembly line tasks. In the
corporate mindset, you can even
innovate and
invent by following a process.
The supposed "process" for writing a computer program is to start with a flowchart and then code from it.
It's well known that programmers ignore the process and just code.

While the
common man would have some trouble
creating a silk purse from a sow's ear, or inventing a machine to produce such purses rapidly, technically competent individuals have found that
TRIZ, a structured process for invention, can be useful. The power of TRIZ lies in the principle that you need to dig down to the essentials of a problem in order to discover a unique solution. This usually involves a resolution of contradictions, such as removing
material to save
weight will also cause a reduction in
strength.
One other good piece of advice taught by TRIZ is to look for solutions to similar problems. If your object is to
polish bowling balls, a slightly modified
apple-polishing process might work just fine. Looking at the history of
wheeled transportation, we somehow went from the
horse-and-buggy case in which the motor was external to the
vehicle, to the case in which the motor is integral to the vehicle. Might there now be some advantage to going back to the external motor case?
Norwegian-
American inventor,
Ole Evinrude (1877-1934), who was born on this date in 1877, may have entertained such an idea when he invented the first practical
outboard motor in 1907.[1-3] Evinrude's family settled in
Wisconsin after
emigrating from
Norway, and he worked as a
machinist in
Milwaukee,
Pittsburgh and
Chicago. During a
picnic in 1906 with his future
wife, Evinrude rowed five
miles in the summer's heat to get
ice cream. He realized on that trip that a
gasoline engine would be a good accessory for a
rowboat.
With much practical experience in hand, he co-founded the custom
engine firm Clemick & Evinrude, and by 1909 the Evinrude Motor Company was founded in Milwaukee. Evinrude's idea still survives in
Evinrude Outboard Motors, which is owned by
Bombardier Recreational Products.

Evinrude's prototype two-cycle engine, in which oil and gasoline are mixed, had a weight of 62-pounds, and it developed 1-1/2 horsepower. It was started by a crank attached to a flywheel, as can be seen in the figure.
Evinrude's wife said it looked like a coffee grinder.[1]

Richard Edler von Mises (1883-1953), who was a
Professor of
Aerodynamics and
Applied Mathematics at
Harvard University, was also born on this date in 1883. Von Mises is well known to
materials scientists for his work on
solid mechanics, especially for the
von Mises yield criterion; but, he is known, also, in aerodynamics,
aeronautics,
statistics and
probability theory.
Von Mises was the first to explicate the
birthday problem, which I wrote about in a
previous article (The Birthday Problem, August 4, 2010). The birthday problem is simply stated - How many people do you need in a room, such that it's more likely than not that two of them have the same
birthday?
It's important to realize that we don't insist that any person has a particular birthday; or, that any person has the same birthday as one particular person. We're just interested in the
probability that any two people will have the same birthday. The surprising result, as derived in my previous article, is that it takes just 23 people to have a 50.7% probability that two will have the same birthday.

Von Mises was an applied mathematician who made important contributions to many engineering fields.

Also born on this date, with
Swedish ancestors just
East of Evinrude's
Norway, is the American
chemist,
Glenn Seaborg (1912-1999), the only person having a
chemical element publicly named in his honor during his lifetime (
seaborgium,
Sg,
atomic number 106). Working at
Lawrence Berkeley Laboratory, he was the only person to have a unique "chemical address;" namely, seaborgium,
lawrencium,
berkelium,
californium,
americium.
Seaborg was principal discoverer or co-discoverer of ten elements:
plutonium, americium,
curium, berkelium, californium,
einsteinium,
fermium,
mendelevium,
nobelium and seaborgium. For such dedication to his science, Seaborg shared the 1951
Nobel Prize in Chemistry with
Edwin McMillan "for their discoveries in the chemistry of the transuranium elements."[4]
Seaborg also discerned the proper placement of the
actinide series elements in the
periodic table, and he was
chairman of the
United States Atomic Energy Commission from 1961 to 1971. Seaborg advocated peaceful uses of
radionuclides for
power generation and
medical applications, and he contributed to passage of the
Limited Test Ban Treaty, the
Nuclear Non-Proliferation Treaty, and the
Comprehensive Test Ban Treaty. He was author or coauthor of more than 500
scientific publications and fifty books.
