Floodlamp technology marches on

In our home we have lots of 3-1/2-inch diameter R30 floodlamps mounted on sockets recessed in the ceiling. (There are six in the kitchen, and four in the living room). When we moved in there were 65W incandescent lamps. Three years ago we replaced those with 15W warm-white compact fluorescent lamps. The fluorescent lamps started slowly and were not dimmable.

At the Boise Costco store on January 11th I saw some 8-packs of 9.5W dimmable R30 daylight LED floodlamps (as shown above)  that normally were $26.99 but had a $16 rebate. I bought one package. The final price including sales tax was just $1.46 per lamp. These LED lamps are instant-on and seem brighter, although their output actually is rated at 650 lumens versus the 750 lumens for the compact fluorescents. Later I bought two more packs for the halls and master bedroom.

Quality control on the LED lamps wasn’t wonderful. On one the threaded end broke away from the body when I tried to screw it into a kitchen ceiling socket (with my suction-cup-on-a-broomstick light bulb changer). So, I got out a ladder and removed the body by hand. Then I used a needle nose pliers to unscrew the threaded end that still was lodged in the socket. I could see a power supply circuit board inside the lamp body, so I got out a hacksaw and pliers and dissected the failed lamp.

Near the front there are seven LEDs (yellow rectangles) on a circuit board held by four tabs onto an aluminum reflector. At the center is a two-pin socket where the power supply circuit board plugs in.

Here is a top view of the circuit board.

Here is a bottom view of that circuit board, with more surface-mounted components which include 9 capacitors (C), 4 diodes (D), 2 inductors (L), and 17 resistors (R).

Using imaginary or abstract visual aids

Even imaginary visual aids can be powerful in a speech. You always can talk about and point to things that aren’t there. On page 180 of his 1996 book Plain English at Work Edward P. Bailey gave three examples. Two are:

“One person was showing the distance someone could broad jump. So she made the stage an imaginary place for the event, started at one edge, and walked the distance for the high school record. She talked about that awhile, then moved a little farther to show the collegiate record. And so on.

....Another made the stage an airport, showing which directions the planes would take off and land, where the gates were, and where the control tower was. She then used this to illustrate the various traffic patterns the planes would fly, depending on the direction the wind was blowing.”  

An airport also could be shown abstractly on the stage using rope and colored yarns to mark runways and taxiways, and sheets of paper to indicate the control tower and terminal. Your audience will imagine the details.

Know Something. Say Something. Be Something.

On January 15th John Zimmer posted Quotes for Public Speakers (No. 248) Elbert Hubbard at his Manner of Speaking blog which was:

“To escape criticism: Do nothing, say nothing, be nothing.”

It follows the familiar Rule of Three. Back on January 9, 2015 Quote Investigator looked at where else it came from.

But I recognized it as being a negative version of something similar to the 1927 motto of Taylor Allderdice High School, which I graduated from in Pittsburgh and is:

“Know Something. Do Something. Be Something.”

The U.S. Army also uses a three-part leadership slogan of Be-Know-Do, which was written by Major Boyd M. Harris in 1983.

A better positive version for speakers is to:

Know Something. Say Something. Be Something.

Are great teachers great storytellers?

Yes, they are. That was the title of a magazine article by Frank Romanelli on page 93 of the August 2016 issue of the American Journal of Pharmacy Education (Vol 80, No. 6). He said:

“....Have we as teachers forgotten the importance of storytelling? Some speculate that growing demands to teach more to more students alongside the over reliance on PowerPoint presentations and other technologies have led many educators to stray from telling the larger story. Stories are a connected means of presenting and transmitting information. Moreover, information that is presented in a logical and systematic fashion is often easier for students to understand, process, retrieve, and synthesize. Perhaps the greatest strength of storytelling is the naturalness of this mode of information transmission. For most of us, our education started informally through fairy tales, fables, and even family stories.

The effective use of storytelling as a component of teaching may be too often overlooked. Telling the story of a disease, disease state, or any lesson on a micro or macro level may be invaluable to students. The story of a disease helps learners understand circumstances surrounding recognition of an altered health state and the chronological events that shape the pharmacotherapy used to treat or cure. By providing a narrative account, a storyline forces students to better understand the circumstances that lead to drug discoveries, obstacles to treatment, and advantages and disadvantages of specific therapeutic options. A paramount lesson from the narrative is comprehending what leads researchers or clinicians to ask certain questions or make certain hypotheses concerning a disease.”

Free return address labels in the mail from charities are an opportunity, not a problem

On January 9, 2017 Jane Genova blogged about Unsolicited Junk Gifts from Supposedly Worthy Causes - Ask Congress to Ban This Kind of Snail Mail. (Titles of posts from her Speechwriter-Ghostwriter blog show up under Speaking Pro Central at Alltop Speaking, which I glance at every day). She had received address labels and a notepad from St. Jude’s Children’s Research Hospital. Jane ranted that:

“....The brutal reality is that gifts, even junk gifts, impose obligation. The expectation is that we will reciprocate. When a cause approaches us in this way, of course, the expectation is for a monetary donation.

I want this stopped. And since the public nuisance happens through the mail, federal authorities can end this practice. That will force good causes to become more innovative in their fundraising. That will provide more assignments for us in marketing communications.”

But there was no reason to go on a guilt trip or try to change the law. The existing one is adequate, and it says there is no legal obligation. A web page at the U. S. Postal Inspection Service titled Receipt of Unsolicited Merchandise explains in plain English that after you open it you can treat it as a gift and either:

A]  If you like what you find, you may keep it for free.

B]  If you don’t like what you find, you may throw it away.

They also refer to the law (Section 3009 of Title 39 of the United States Code). I found it amusing that Jane, who likes to name drop about having attended Harvard Law School, didn’t even bother to look up the law on this topic. (She also cross-posted this same story at her Law and More blog).

I suspect that Jane didn’t spend much more time writing her blog post than I did reading it. She’s a bad example, as I discussed previously on December 28, 2016 in a blog post titled Shallow versus deep research about how much Americans trust their mass media.

Return address label sheets from charities are a useful gift, and thus are my favorite type of ‘junk’ mail.

Is expertise really the enemy of innovation?

I think not, but is tip #15 from Stephen Shapiros’s 2011 book Best Practices are Stupid. He blogged about it in an August 31, 2016 post titled Innovation Minute #20: Expertise is the Enemy of Innovation. (Titles of his posts appear at Alltop Speaking). Stephen explained that:

“The reason why is, the more you’ve thought about a topic, the harder it is for you to think differently about that topic.

So, if you’re an expert in a function, like HR, finance or sales, it’s going to be hard for you to think differently about that. If you’re an expert in an industry, like hospitality, financial services or manufacturing, it will be difficult for you to think differently about that.”

Alexander Pope’s old adage that a little learning is a dangerous thing likely is more correct. I instead think that expertise is a necessary (but not sufficient) condition for innovation.  

If you are dogmatic and rigid, then expertise MAY be the enemy of innovation. But those of us who have done research for a living know how to be flexible and creative. My first career included seven years of applied research at the Climax Molybdenum Company lab in Ann Arbor, Michigan. There were lots of creative people in that lab with a wide variety of expertise. Two stories illustrate how expertise leads to innovation.

One of our older technicians, Bob Besore, had once designed production tooling at Garwood Industries. In our mechanical testing lab we had a fracture test apparatus that (as is common in research) had been adapted from other tooling we already had around. But setting it up took repeated measurements and several minutes of adjustment with a wrench to align the differently sized and shaped upper and lower plates mounted on the fixed and movable heads of the electrohydraulic testing machine.

A supervisor asked Bob if he could make an easier to use version. He said sure I can, but I need to start over from scratch. A top view of what he designed is shown above. The new precision-ground plates were the same size and shape. A precision-ground U-shaped coupling fixture slid over both plates to locate them in perfect alignment. Then a series of cap screws were tightened with an air wrench, and in under a minute it was ready to use. These days what Bob had designed is described under the topic of lean production as a Single-Minute Exchange of Die (SMED).   

Another example is the 1989 U.S. Patent # 4,832,757 by Thomas B. Cox and me (Method for producing normalized Grade D sucker rods). Sucker rods are what connects between the horse head pumping jack you see in oil fields and the pump mechanism located at the bottom of the well. The high-strength Grade D usually is produced from plain carbon steel via a heat treatment  involving austenitizing, quenching and tempering. Lower strength rods are normalized - austenitized and just air-cooled. We showed that carefully chosen normalized manganese-molybdenum alloy steel compositions also could produce acceptable properties. This research was begun during the 1980s drilling boom, when there was a high demand for rods. We wanted to let rod producers who were set up only for heat treating lower strength rods (and thus didn’t have a quench tank and tempering furnace) make high-strength rods too. 

The general approach of replacing a carbon steel with an air-cooled alloy steel had previously been used at the Climax lab for other products, like dual-phase steel sheet for automotive applications. We used our lab’s collective expertise in hardenabilty to select the right steel compositions.

Horror stories about being introduced

In the September 2016 issue of Speaker magazine (from the National Speakers Association in the U.S.) there is a useful article on pages 30 to 32 by Glenn Strange titled When Introductions Go Bad. Glenn tells some horror stories about how he has been introduced, and why you need to write your own introduction. In a sidebar he provides 15 Tips to Ensure Success

The Toastmasters International web site has a web page linked to a downloadable guide for Creating an Introduction from their Better Speaker Series.
