THESE ARE THE LAWS HERE
In
the 1950s, when my family was driving through rural Ohio, we'd often
encounter restrictions when entering a town. No peddlers
allowed! No muffler cutouts!
My
parents explained that those signs were holdovers from the
1930s. The villagers didn't want unemployed transients coming
onto their porches trying to make a buck. In those days,
residents didn't shoot strangers knocking on their doors; they merely
called the cops.
Also,
the villagers didn't want loud motor vehicles revving their
engines. Apparently some older cars (and some modern hotrods)
use cutouts to bypass the muffler in the exhaust system,
thereby gaining a little power and efficiency. Only out in the
countryside was that legal, because an unmuffled engine makes a lot
more noise.
Morral,
Ohio, 23 miles from my old home, still tempers its welcome with a
warning or two.
The
Green River Ordinance makes it illegal for uninvited
callers to sell items door-to-door; the city of Green River, Wyoming,
enacted the first such ordinance in 1931, and Morral followed suit in 2017.
But
what about the prohibition on engine braking, adopted
six years before? What exactly is engine braking? |
 |
When
I'm driving down a steep hill, I prefer to save the wear and tear on
my brakes by shifting to a lower gear. The car's momentum,
acting through the transmission, forces the engine to turn faster to
keep up. The noise level goes up as I hear the RPMs suddenly
increase. But my foot is off the accelerator, so the engine has
to slow down, and that slows the car.
However,
most folks in farm country will just use their normal brakes.
Morral has no hills. What's the problem?
Well,
Morral does have a grain elevator, next to the railroad crossing,
and commercial trucks loaded with corn and wheat and soybeans will
stop there occasionally. The town also boasts two large
fertilizer companies.
 |
 |
A
braking system specific to diesels, known as a Jacobs brake, can use
the engine to assist the vehicle's air brakes. The driver
presses a button to shut off the fuel to certain cylinders and
exhaust their compressed air, loudly. Use of these Jake
brakes is very loud, like this,
and would annoy the Morralites. They'd prefer the truckers to
slow down more gradually by using only their standard air brakes.

MOVIN' ON UP
Wilder
Hall has stood on the campus of Oberlin College for 112 years.
For more than half that time, my former college radio station WOBC-FM
made its home on the west end of the third floor.

Now
the building is being remodeled. I'm told that the station has
been relocated to smaller quarters on the fourth floor, unfortunately
leaving behind the memories of 14 generations of students. I
tell what I've heard in WOBC
Moves Upstairs.

Does
ChatGPT sound like this website? It should, at least a tiny
bit. According to Washington Post research,
t2buck.com's 130,000 tokens make it the 161,865th largest domain
among those that were scraped for Google's C4
dataset. C4 is a massive snapshot of the contents of 15
million websites [including more than half a million personal blogs]
that have been used to instruct some high-profile English-language
AIs, called large language models, including Google's T5 and
Facebook's LLaMA.

BIG BLOWUP
What
went wrong with the unmanned SpaceX rocket launch on April 20?
In
a series of tweets yesterday, aerospace engineer Christopher David
blamed a person who's been the subject of many social media comments
lately, the founder/CEO/chief engineer of the company, one Elon Musk. |
The
failure of the SpaceX launch can be directly linked to a personal
decision that Elon Musk made three years ago to not install flame
diverters on the Starship launch pad. He overruled his own
engineers. Hubris. It's his fault.
Because
of this decision, the launch pad was blasted apart and debris
slammed into the engines at the bottom of the booster, damaging them
and ultimately resulting in the spectacular cartwheels and explosion
that we saw just moments later. |
 |
Jeff
Stirling observed: It's arguably true and James
Oberg wrote about this years ago that the success of Apollo
was at least in part due to the reliability of the five huge Saturn V
engines, as opposed to the Soviet Union's necessity to use 15-20
separate, smaller engines that had to fire simultaneously.
 |
The
first stage of the Starship Super Heavy has 33 separate,
smaller engines three in the middle, then a ring of 10, then
an outer ring of 20 that have to fire simultaneously. Or
at least they're supposed to.
Vanmojo
observed: Shortly after the vehicle cleared (what was
left of) the tower, they showed the engine carriage, and it was obvious
not everything fired as planned. |
A
chart posted online recorded that three of the Raptor engines were
not running at liftoff. Nevertheless, with 91% power the rocket
managed to clear the tower, allowing Musk to claim success.
Another Raptor failed at 41 seconds into the flight, a fifth at 1:03,
and a sixth at 1:41.
Here's
where they eventually ended up, writes Christopher David.
Eight out of 33 engines failed, for a reliability rate of
75%. That's super, super bad.
With
so many engines out on one side, the gimbal range was exceeded, and
there was no way to prevent the rocket from veering to that
side. At 2:50, the stack decoupler failed to separate the stages. |
 |
Following
more than a minute of out-of-control tumbling, for safety reasons it
was necessary for the Flight Termination System to destroy the
vehicle. Blowed it up real good. Presumably, they'll try
again next year.

"MALICE"? ACTUALLY?
Was
Dominion Voting Systems defamed by Fox News when the latter falsely
told its viewers that the 2020 Presidential election had been
stolen? A trial is beginning tomorrow morning in a Delaware courtroom.
Any
plaintiff in a defamation case has to prove that the allegedly
defaming statements involved facts (not mere opinion), that those
facts were false, and that the plaintiff was harmed when
those statements were delivered to others. In addition, in this
case Dominion also has to prove that Fox behaved with actual
malice meaning that its hosts and executives either knew
the claims were false or had a reckless disregard for the truth (a
high degree of doubt), but aired them anyway.
That
may be the way lawyers define actual malice, but I don't
like the word choice. In common usage, malice implies
evil intent. Malice is a deliberate desire to harm the
aggrieved party, in this case Dominion, but that was not actually
Fox's objective.
Fox
News reporting may have harmed Dominion's business, but Fox wasn't
doing so because it hated the voting machine company. It didn't
care about Dominion. (That's not an excuse for lying about the
election, it's just an observation about motive.) |
|
|
|
Fox
News lied because it didn't want to be harmed itself. It
didn't dare disillusion its right-wing viewers with truths that they
didn't want to hear, because that would have driven them away and
depressed Fox's ratings and the value of its employees' stocks.
So the network told its devoted fans a sensational story which they
were only too happy to believe. |
 |
|
 |
ADDENDUM:
The trial never happened. In a settlement, Fox agreed to pay
$787.5 million to Dominion. "Progressives crowed that
Fox's reputation would forever be damaged by the revelation that the
channel was knowingly lying to its viewers," David A. Graham
wrote in The Atlantic. "Perhaps on the margins
that's true, but hoping for widespread epiphany is naive. The
viewers either don't care or refuse to recognize what's going
on. The viewers hold the real power, and Fox is at their
mercy. That scares executives far more than any cadre of fancy
defamation lawyers ever can and the lengths that they might go
to avoid losing their viewers should scare everyone else."

TWO STUDENTS IN A SINGLE

I returned to my college dorm room after dinner and undid my tie, my

TWO BITS OF "INSIDE GRAPHICS"
 |
At
the start of the 2023 NASCAR Cup Series season on Fox TV, the top of
the Pylon the running order on the left side of the screen
looked something like this simulation.
The
Racetracker the horizontal bar graph is a
visualization of how many laps have been run under the green flag and
under the yellow caution flag. Lead announcer Mike Joy
explained this new feature, asked us viewers how we liked it, and
invited us to make our opinions known. You know how to
reach me. |
I
did like it. We can see a summary of the overall progress of
the race, which is helpful if we've zoned out during parts of the
four hours of coverage. But the green and the yellow were too
similar. I had to squint to tell the sections apart, especially
on a smaller screen. The green doesn't need to be the brilliant
color bars tone; it could be a somewhat darker shade.
 |
I
considered tweeting Mike with that suggestion. We've met, you
know; I recall briefly
conferring with him on a graphic before a telecast 33 years ago.
However, it just might be possible that he doesn't remember me.
I thought better of the idea.
However,
someone else on the Fox crew noticed what I had noticed. By
the next week, the Racetracker colors had been adjusted. Here's
an actual frame grab. Great minds think alike! |
UPDATE,
MARCH 11, 2024: The Racetracker can actually come in
handy. Yesterday afternoon I left my apartment before the
telecast of the Shriners Children's 500 from Phoenix Raceway, but my
cable box was tuned to Fox. It was temporarily recording the rac e.
When I returned, I noticed that the event was under caution.
On the right end of the Racetracker were four yellow bars,
closely spaced. What the heck had happened? I rewound the
DVR and discovered that the first bar represented the break between
Stage 2 and Stage 3, while the other three represented spins
resulting in caution flags, pit stops, and frantic double-file
restarts. All of that seemed more interesting than ordinary
green-flag racing where the cars just go around and around in
ovals. And between wrecks, the DVR allowed me to fast-forward
through the commercials. |
Speaking
of great minds, both Doug Glanville and Keith Olbermann have noted
the unfortunate font choice on the back of Atlanta Braves uniforms.
Dylan
Dodd is a rookie pitcher whose jersey seems to believe his name is
DODO. Or DOOO. |

To
avoid ambiguity of this sort, when I'm entering a capital D in a
crossword puzzle I exaggerate the serifs. Maybe not this much,
but you get the idea. |

I'VE
GOT IT PEGGED
You
cant fit a square peg into a round hole. Nor can you fit
a round peg into a square hole. But which comes closer
to fitting?
Last
Friday night, we broadcasters had just finished televising an
exciting hockey game; the Pittsburgh Penguins defeated the New York
Rangers in a shootout. As we put away our TV toys, cameraman
Chris Dahl reminded me that I had once posed and answered the peg
question. It must have been 20 years ago.
First
consider a square hole, one inch on a side. The
cross-sectional area is 1.000 square inch. The largest round
peg that can be inserted into this hole has a diameter of one inch
and a radius of one-half inch, so its cross-sectional area (pi times r2)
is 0.785 square inch.
Then
consider a round hole with the same cross-sectional area as the
first hole, 1.000 square inch. Its radius is 0.564 inch (the
square root of 1/pi), so its diameter is 1.128 inch. The
largest square peg that can be inserted into this round hole measures
1.128 inch along the diagonal. By the Pythagorean theorem, the
peg measures 0.798 inch along the side. Its cross-sectional
area (0.798 squared) is 0.636
square inch.
So
78.5% of a square hole
can be filled by a round peg (or dowel), but only 63.6%
of a round hole can be filled by a square
peg. (Compare the size of the empty space in the corners.)
Now
we know. Dowels rule! |

ST. JOHN PASSION
On
this very night 299 years ago, in the Nikolaikirche in Leipzig,
Germany, the Good Friday Vespers service lasted about three hours.
The
scripture came from the Gospel of John, interspersed with comments
such as Lord, through your Passion, show us that even in the
lowliest state you are always glorified! Or, in the
original rhyming German:
 |
 |
Remarkably,
except for the sermon, all the words were sung. The music was
composed by one Johann Sebastian Bach, then in his first year as
choirmaster of St. Thomas's Church and School.
Three
centuries later, I've provided a YouTube link to a performance plus
a translation. Imagine a rainbow blooming from Jesus's
bloodstained back and also Heavenly
Flowers from His Thorns.

CAN'T REWIND RADIO
I
mostly ignore radio commercials, but I perked up when I heard one of
them mention the borough of Tarentum. That's just half a mile
from where I live, and a new store was opening in the nearby
mall. The ad mentioned phones and accessories, twice giving the
address as 2015 Pittsburgh Mills Boulevard. But what kind of
store was it? I had to do online research; it turned out to be
a Verizon outlet. Later I heard the ad again from the beginning
and noted that the sponsor was mentioned in the second sentence but
never again.
Another
commercial caught my attention with a clip of an exciting recent
goal by the Pittsburgh Penguins. It then continued with
It's the only meeting between these long-time rivals in
Pittsburgh this season! Get your tickets at....
Presumably they had mentioned the date and opponent before playing
the clip but failed to repeat that information afterwards, so I still
don't know what game was being promoted.
A
couple of poorly-constructed commercials, if you ask me. Text
or print ads at least allow us to go back and recheck the part we
skipped over.

FOUND
AT CRACKER BARREL
When
my mother was in high school,
a man held to be irresistibly attractive to romantic young
women was called a sheik.
In
the spring of 1930, my future mother was voted the Prettiest Girl in
school for the second straight year, while her boyfriend at the time,
Durward McKee, was voted the Biggest Sheik for the second straight year.
 |
And
the May 17, 1930, edition of the popular Liberty magazine
featured an illustration by Leslie Thrasher entitled The
Sheik, in which a girl draws a monocle and mustache on her
little brother to make him irresistibly attractive.
I
noticed a framed copy of this cover hanging on the wall next to my
table at a local Cracker Barrel restaurant, and I found an image of
the cover on the Internet.
What
was inside this edition? The Internet knows everything.
Further research reveals that in one passage, the humorist Robert
Benchley described falling briefly asleep every minute, a phenomenon
I would later experience in window seats on airplanes.
The
article was entitled Sporting Life In America: Dozing. |
Dozing
before arising does not really come within the range of this
treatise. What we are concerned with are those little lapses when we
are fully dressed, when we fondly believe that no one notices. Riding
on a train, for example.
There
is the short-distan ce
doze in a day coach, probably the most humiliating form of train
sleeping. In this the elbow is rested on the window sill and the head
placed in the hand in an attitude of thought. The glass feels very
cool on the forehead and we rest it there, more to cool off than
anything else. The next thing we know the forehead (carrying the
entire head with it) has slid down the length of the slippery pane
and we have received a rather nasty bang against the woodwork. They
shouldn't keep their glass so slippery. A person is likely to get
badly hurt that way.
However,
back again goes the forehead against the pane in its original
position, with the hand serving more or less as a buffer, until
another skid occurs, this time resulting in an angry determination to
give the whole thing up entirely and sit up straight in the seat.
Some dozers will take four or five slides without whimpering, going
back each time for more with apparently undiminished confidence in
their ability to see the thing through.
It
is a game that you can't beat, however, and the sooner you sit up
straight in your seat, the sooner you will stop banging your head.
