29, 2017 BELIEF
IN ALTERNATIVE FACTS
I
wrote the following in a letter on December 20, 1993.
We
like to believe were invulnerable. We know better, of
course, which is why we take precautions; but we cant spend all
our time worrying about the various parts of our bodies that might
break or swell or otherwise malfunction. So we believe
that everythings going to be just fine, although we know
that theres a chance something will go wrong.
An
example: Gerald Posners book on the JFK assassination, Case
Closed. After showing that
the evidence still points to a disturbed Lee Harvey Oswald acting
alone, Posner explores why so many people still believe
that there were other shots, other conspirators.
He
quotes historian William Manchester: Those who
desperately want to believe that President Kennedy was the victim of
a conspiracy have my sympathy. I share their yearning.
...If you put the murdered President of the United States on one side
of a scale and that wretched waif Oswald on the other side, it
doesnt balance. You want to add something weightier to
Oswald. It would invest the Presidents death with
meaning, endowing him with martyrdom. He would have died for
something. A conspiracy would, of course, do the job
nicely. Unfortunately, there is no evidence whatever that there
was one. |
|
And
from another medium, the comics: Doonesbury
for December 9, 1993, has Duke on a computer bulletin board trying to
sell new evidence to rabid conspiracy theorists.
That
somehow reminds me of I Corinthians 15:14,19, for what its
worth: If Christ was not raised, then our gospel is null
and void, and so too is your faith. We of all people are most
to be pitied. The truth would destroy these people. |
His
appeal, according to an Alan Levinovitz article
headed Trump Supporters Refuse to Believe Their Own Eyes only
two days ago, lies in the salvific vision he has sold to his
supporters a compelling narrative of paradise past, the fallen
present, and a glorious future. For his followers, it is
essential to reinterpret apparent facts so they fit this
narrative. Otherwise, they lose the hope it provides and the
dignity theyve invested in its truth. And that can also
mean confronting existential panic without a panacea.
JANUARY
27, 2017 APOLLO
1
On
this evening 50 years ago, a flash fire erupted inside the Apollo 1
command module during a test on the pad at Cape Kennedy, killing the
three astronauts trapped within. As a college sophomore, I
heard about it in the dining hall the next morning. |
|
That
summer my family visited Expo 67 in Montréal. Inside
the huge geodesic dome of the United States pavilion, one of the
displays featured an earlier Apollo capsule that had parachuted back
to earth from an unmanned test mission. The scorches on the
outside of this white spacecraft were the result of the heat of re-entry,
but unfortunately they reminded me (and countless other visitors) of
the fiery tragedy a few months before.
Manned
flights were suspended for nearly two years while NASA engineers
redesigned the spacecraft with better wiring insulation, a less
oxygen-rich atmosphere, and non-flammable materials in the cabin and
the astronauts suits. The hatch on future vehicles could
be opened outward in less than five seconds. Apollo 7 flew in
October 1968, and the project eventually met its goal of landing on
the moon before the decade was out.
JANUARY
25, 2017 MARK
IS PAUL IN A DIFFERENT GENRE
The
Renaissance master Albrecht Dürer painted this panel in 1526,
during the Reformation. It depicts the wide-eyed evangelist
Mark and the aging apostle Paul.
Bible
scholars tell us that Mark was the first to write a gospel.
But where did he get his information?
Ive
only recently learned that some scholars believe his source was
Paul. To give a human dimension to Pauls heavenly
Christ Jesus, Mark wrote an allegorical biography of a
person here on earth called Jesus Christ. [Romans
1:1, Mark 1:1]
Perhaps Mark's earthly Jesus never really existed!
How
could this be? After a great deal of studying and
cross-referencing, Ive written a two-part tale in which I
imagine meeting with Mark and Paul in first-century Rome.
The
first half is now online. Its the latest in my series of
rewritten Bible stories, though this one is actually a rewritten
story about how the Bible came to be. I call it Fleshing
Out Jesus. |

JANUARY
21, 2017 GET
ME AN EKG AND AN MOG
When
the science nerds on The Big Bang Theory debate whether
theoreticians are smarter than engineers, they challenge
each other with questions like According to M-theory, how many
dimensions are in a brane multiverse? or What is the
melting point of praseodymium? However, the ability to
recite facts merely shows that one is educated, not
necessarily smart (or innately intelligent).
And
when the characters on that show wonder whether something is true,
one of them often suggests conducting an experiment to find out. |
|
Of
course, the writers are using a bit of dramatic license. We
nerds dont actually claim to be smarter than non-nerds, nor do
we propose small-scale experiments on a weekly basis.
But
it has been known to happen. When I was a junior in high
school, I noticed that my moods varied from day to day, so I decided
to experiment on myself by keeping a chart.
During
the year 1964, I estimated my mood every evening on a scale of 1
(very grumpy) to 10 (perfect). After writing down the Mood
Estimates (MEs), I traced my moodogram on a long strip of paper.
I
did anticipate finding one pattern in my data: a seven-day
cycle. Moods should vary somewhat depending on the day of the
week. However, wed expect much greater influences from events
(pleasant or unpleasant) and from randomness (reasons unknown).
|
I
recorded some perfect days with ME = 10. One of
them was Tuesday, February 10. My parents took Terry Rockhold
and Carl Martin and me to St. John Arena in Columbus to see an Ohio
State basketball game. And what a game it was! The
Buckeyes defeated Illinois 110-92 as Gary Bradds set an OSU record by
scoring 49 points.
Later
that year, the portion of the chart reproduced below shows that
Fantasia on April 23 (the high schools Mixed Chorus
concert featuring the musical Pal Joey) was a high point for
me. So was the first Saturday in May, when students went to
Westerville for the state scholarship test and then returned home for
the annual Richwood Relays track event.
But
that was followed by The Week. I had the responsibility of
chairing the Decoration Committee
for the Junior-Senior Prom, so my moods were low during the busy days
leading up to it. |
Afterwards,
my moods gradually recovered. I have no record of why I was so
elated on May 17.
On
the part of the chart not shown, I recorded my ME on June 10 as a
medium-high 7. Surprisingly, that was the day my father's
business burned. Other days were
lower, though I didnt ascribe reasons to them until a
year-end letdown on December 23.
|
So
was there a weekly cycle? Yes, but not an overpowering
one. I averaged my 52 MEs for Mondays, 52 MEs for Tuesdays, and
so on. Sundays turned out to have the highest average with ME =
5.08. Wednesdays were lowest at 4.13. |
I
was happier on the weekend (4.84 Friday through Sunday) than during
the week (4.33 Monday through Thursday). Thats a rather
small range. But the qualitative result is not unexpected; we
are often least happy on Wednesdays, when we have to console
ourselves that its Over-the-Hump Day.
Ive
recently re-analyzed my data in relation to two hypotheses.
Each predicts a cycle of moods/emotions. (I assert that moods
and emotions are equivalent.)
Hypothesis
A is based on biorhythm
theory, which would become a fad a few years later but has since
been discredited. In the 1970s, some people were tracking their
cycles like astrologers. You supposedly are controlled by three
sine waves that begin oscillating at the moment of birth: a
23-day physical cycle, a 28-day emotional cycle, and a 33-day
intellectual cycle. If all three are favorable, youre
going to have a good day.
Thats
ridiculous, of course. Over the course of your lifetime you
would expect each cycle to slip a day or so occasionally, so the mere
fact that youve counted precisely 13,505 days on earth
doesnt determine your present state. Physiologist Gordon
Stein called biorhythms a hoax, just another pseudoscientific
claim that people are willing to accept without required
evidence. Those pushing biorhythm calculators and books on a
gullible public are guilty of making fraudulent claims.
Be
that as it may, Hypothesis A would predict a 28-day emotional cycle
(the smooth gold curve) starting 6,160 days before New Years
Day 1964, or exactly 220 cycles from the day I was born. Each
blue diamond represents the average of 13 MEs, four weeks apart.
But the chart shows no relationship between my scattered diamonds
and the biorhythmic theory.
|
|
Hypothesis
B predicts a day-of-the-week cycle. The curve on the right has
been aligned to start on Friday. The blue days from my
moodogram data tend to support the hypothesis. (Exception: my
4.64 Saturday ME falls far below the curve, perhaps because I
wasnt very active socially. Sundays were better because
of church activities.)
But
this is certainly not scientific proof of anything. There are
only 366 data points, much too small a sample to draw any
conclusions. The points represent subjective estimates from
only a single nerdish individual. Your moods may vary. |

G. BIV? WYC G. MRB!
Way
back in 1953, the National Television Standards Committee (NTSC)
published a protocol for color television that would be compatible
with the black-and-white TVs already in use in the United States.
RCA
engineers (right) had created a color TV picture tube, and the
Society of Motion Picture and Television Engineers designed a test
pattern that could be used to calibrate color TV signals. It
consisted of vertical bars composed of 2 on/off states of each of the
3 primary colors of light, which can be combined in 23 = 8
ways to make 8 colors (seven hues plus black). |

Why
was this test pattern necessary? NTSC signals, being analog,
were seemingly Never Twice Same Color. When the chroma
information slipped out of phase, incorrect hues resulted.
The
two examples on the left are about five degrees off in either direction.
Look
at the second bar from the left, which is supposed to be
yellow. One example appears too green and the other too red,
but how do we know whats correct? Try to split the difference?
At
home, people would adjust their tint control until faces
looked right. |
|
In
TV production trucks, I often worked with professional monitors that
had a blue button to switch off the red and green
channels, leaving only the blue.
If
the monitor was incorrectly set up, the cyan and magenta bars would
not have the same intensity of blue, as in the upper example of an
extreme misadjustment. So Id turn the tint knob
until they matched, as in the lower example.
Also,
if the white and blue bars didnt have the same intensity of
blue, Id turn the color knob.
|
Now
that television has become digital, color-bar adjustments are no
longer necessary. However, the time-honored bars still show up occasionally.
For
TV executive Fred Silvermans 2009 presentation at his alma
mater (and mine), Syracuse University, this poster depicted a network
television schedule using the seven colors for the seven days of the week. |
|
|
At
my apartment, I've honored the tradition by using the same scheme to
label the dry-erase board on which I keep my to-do calendar.
Sunday is white, Monday is yellow, Tuesday is Toozequoise, Wednesday
is green, Thursday is Thurple, and so on.
And
to help remind me which day it is today, theres a pole light
accenting a magnifier and a bobblehead in one corner of my living room.
When
Sunday becomes Monday, I switch off the blue bulb, and so on.
The primary colors still live! |

TV NEEDS MORE DISTRACTIONS?
On
its high-definition channel, PBS is still occasionally running (at
odd hours) a 1998 explanation of digital television by Robert
Cringely. He promotes the wonders of this new technical advance
while talking with various folks, including two PBS personalities who
are no longer with us, Fred Rogers and Julia Child.
One
digital advantage is the much-touted concept of interactive TV.
Using your remote control, you could click on icons on your screen
to bring up other, more detailed information, such as the chef's
recipe or the manufacturer's specifications.
Advertisers
have shown mild interest in the idea. It might entice viewers
to click away from the show they're watching and instead see an ad
for their product. Techno-geeks rhapsodize over other
applications like the possibility of choosing alternate camera angles.
But
on Cringely's program, documentarian Ken Burns raises some
objections. Television professionals work hard to select the
best images and arrange them to tell a story. Are we now going
to encourage the viewer to click away from this story to look at
other images or to wander aimlessly through a database?
Fortunately,
nine years later, interactive television still hasn't caught on in
America. We watch a TV program straight through, as its
creators intended. (Well, maybe we use TiVo to pause it or
rewind it, but we're still watching just the program.) Then
after it's over, if we want more details we can use our computer to
find them on the Internet.

15, 2017 AGAINST
ALLOWANCES
The
editor of the Richwood Gazette
published this opinion 126 years ago, warning about permissive
parenting in these modern days.
January
15, 1891
If
you want to ruin an impulsive boy, give him plenty of pocket
money. The recipe is infallible. It has often been tried
and always with the same unhappy results.
By
the time a boy is eight years old, the little solon on wealth has
found the soft side of Pa and Ma. By age ten, they will carry
bank bills in their pockets; and by age 14, they are content with
nothing less than well-stuffed pocketbooks.
Every
father and mother knows this is wrong. Say what they may about
the harsh, austere, uncompromising old Puritans, their stern family
discipline was better than the indulgence by which children are
spoiled in these modern days.
Fifteen
years later, my hometown weekly newspaper again ventured to offer
its editorial observations about adolescent economics.
November
2, 1916
Few
young men care to have their father as the boss. The sons of
several farmers in the vicinity are working for contractors
thereabouts at a lower rate of wages than their own father is paying
farm laborers on the homestead.
In
their younger days, they had enough of dictation from that source,
and they yearn for change, just as the Prodigal Son may have done in
his day.
A
more mighty reason: Working for a contractor, he knows that
his day will consist of a specific number of hours. At the end
of the day, he will have nothing to do until tomorrow. Working
for his father, the day begins at sunrise and lasts until dad is
ready to quit for the night.

MOON
Theres
a full moon tonight!
In
the wee hours of yesterday morning, Tracey Moody posted the photo on
the left, remarking My, you are proud tonight, my radiant
idol. On a previous occasion she had written:
The
Moon showed up to my doorstep this weekend, the brightest Id
seen him in a while. The visit wasnt an anomaly, but
neither was it written in my schedule.
As
I rushed out onto the lawn, I lost my footing, trusting the grass
was still where I last saw it. I blushingly told him,
Pardon my excitement, but I didnt know you were
coming, fearing I appeared to be lacking grace. I gazed
at him, he gazed back, both unbroken, and baring our skin.
The
thing about the Moon is, he has work to do. He has tides to
pull, forests to gently light, and travels to guide. He bears
the burden of the world, even on those nights I feel hes just
shining on me.
Best
not get too whimsical, theres no rope that can lasso the
Moon. Nor should the Moon compromise all of the harmony of the
world so that he can have me. |
A
science skeptic prepared a graphic posing the question on the
right. His gotcha tone implies he doesnt
believe what hes been told.
Scientists
tell us the Moon glows because its illuminated by the
Sun. However, some people say the experts cant be
trusted. Perhaps the glow of the lesser light to rule the
night comes from the halo of the angel who dwells inside.
First
off, I havent seen the skeptics evidence that moonlit
areas are colder than shaded areas. But if thats true,
heres my explanation. |
|
Apparently
the measurements are being made on a winter night. It must be
a clear night, because otherwise there would be no shadows
no difference between moonlight and moonshade.
To
begin the experiment, a thermometer is exposed to the night sky,
into which the days heat is escaping by radiation.
Its chilly out there in the moonlight. Clear nights, when
were not insulated beneath a blanket of clouds, are the coldest.
However,
under a nearby tree, another thermometer is in a sheltered
area. There, as any gardener knows, its less likely to
freeze, being protected from losing so much heat. It reads a
slightly higher temperature.
But
wouldnt the first thermometer be warmed by the moonlight
striking it? Not enough to notice. Moonlight is much
weaker than sunlight.
The
lunar surface is dark gray. In this view from the DSCOVR
spacecraft thats stationed a million miles closer to the Sun,
the Moon is passing in front of the Earth, possibly eclipsing the Sun
for some Earthlings. From this angle we can see what Earthlings
call the far side of the Moon. Its
illuminated by the Sun, but it nevertheless appears very dark.
At
best (that is, during a full moon like tonight, when the Moon is on
the opposite end of its orbit from this picture), only 12% of the
sunlight that hits the Moon gets reflected back toward Earth.
Theres not enough infrared energy in that faint light to raise
the thermometers reading appreciably. |

CALENDAR PUZZLE
|
You
may have seen one of these low-tech calendars.
The
two digits of the date are displayed on the faces of two cubes, which
can be rearranged to form all the dates from 01 through 31.
At
first, you might think that the first cube has digits up to 3, while
the other cube has all ten digits from 0 through 9, as shown in the
table at the right.
But
that can't be, because a cube has only six faces, not ten.
Some of those ten digits that we need to see on the right must be
hiding on the left cube, awaiting a swap to the other side.
How
exactly are the digits distributed on the cube faces? Click here

MUCH OF A GOOD THING?
In
an average 24-hour day, we now can choose from 29.7 nationally
televised sports events.
Last
week, Michael Mulvihill tweeted the numbers that I've graphed at the
right. The annual number of telecasts more than tripled in
twelve years, from 3,144 in 2004 to 10,869 in 2016. Last year's
total was up 7.9% from the year before.
And
in a possibly related statistic, Darren Rovell tweeted that the
average viewership for 2016 Sunday Night Football was 20.3 million
viewers. Thats down 9.7% from the year before. |

THE DYING OF THE LIGHT
It's
a winter afternoon.
Low
in the southwestern sky, a pale sun casts long shadows across the
gray landscape. The day is almost over.
I
check my watch. It's 2:00 pm.
about these flashbacks
For
its first six years, this website emulated a magazine. Each
month I'd publish a new edition with several featured articles.
Then,
ten years ago, it became more of a blog, with a new post every few days.
Now,
with a decade of posts in the Archive, I'm starting to flash back to
some of them. They're articles of enduring
significance, as Readers
Digest
used to claim, and will be reprised here on their tenth birthday. |
JANUARY
6, 2017 THE
POLYGONAL CONFIGURATION
|
I found
this picture of a Lego construction. The design inspired me to
return once again to a problem in Biblical geometry and to come up
with another solution, which I've called Configuration 2.
Ive
inserted that new suggestion into my 2003 discussion of King
Solomons Pi.
That
updated essay thereby becomes this month's 100 Moons article. |
JANUARY
3, 2017 DID
YOU JUST FNEEZE?
Welcome
to Cold & Flu Season. When you get a tickle in your nose,
you'll sniffle and then snort violently.
To
people in the Middle Ages, these rude noises sounded like
f-f-f-f-knees! They desired to write down a word
that might describe this involuntary expulsion of air.
Ignoring
the cats polite suggestion, they decided to call the event a fnese. |
|
But
then printing was invented. If somebody's fnese was to be
mentioned in a book, the word had to be set in type.
Alas,
typesetting at the time had a peculiar requirement. When a
printer needed an s, except at the end of a word, he
reached into his lower case and pulled out a long s.
That medieval letter was supposed to resemble an s in
the handwriting of the time, but it's very similar to an f.
|
Can
you detect the difference between these two words? Look
closely. Only the first of the tall letters has a crossbar that
goes all the way across the vertical stroke. Its an
f. Each of the other three is a long s. |
Modern
readers expect characters like this to have a full-width crossbar,
so all four characters look like f to us. But they
arent; the two words (in modern typography) are
fnese and snese.
The
original printing of the Declaration of Independence appears to
promote the Purfuit of Happinefs while caftigating George III for his
perfiftent refufals. Thats our modern mifunderftanding.
The
oppofite mifunderftanding occurred earlier, when early printers set
in type.
Early
readers failed to notice the tiny little crossbar on the first
letter. The combination fn seemed unlikely, so this
word must surely begin with sn. They mispronounced
the word as snese. In due time the spelling became sneeze.
That's
the explanation
that Paul Anthony Jones gives on Mental Floss, anyway. He also
says a nickname used to be an eke-name,
meaning an also-name. And he learned all this from
Oxford scholars, so it must be true.
