Canned Catfood. Pate vs Shreds & Glop
I prefer pate. It is less messy to handle. Cat prefers shreds & glop. How can I tell? She doesn't eat much pate, but she will have all the shreds and glop eaten within the hour.

Barrows
I was watching a U-tube lecture on European archeology. They excavated a huge barrow in England. Built back in prehistoric times, before writing, all we know about then comes from archeology. It was a big structure, half underground, half above ground. These things are often described as graves. On this barrow, they excavated and found the bones of forty individuals. Forty? Not many for a barrow that big. The place was big enough to hold a 1000 graves. Especially when you think how difficult it must have been to build such a place in the stone age. Few workers, a poor hunter gatherer economy, no metal tools, not even shovels. It must have required powerful motivations to build those barrows.
Barrows are traditional described as grave sites. That U-Tube lecture makes me think that the barrows served other purposes. Tribal gathering places, sacred places where shamans asked the god for good weather, good hunting and good luck. Places where seers predicted the future. We cannot know at this remove in time. I.m thinking those few graves were the graves of a few exceptional individuals, priests, kings, shamans, mighty warriors, buried in the barrow to bring good luck, bring a friendly spirit, and make a sacred place more sacred. We still do this. Look at Westminster where the British bury their kings and scientists and soldiers.

Boeing's Number 1 Problem.
Best selling 737 Max has been grounded for more than a year. This is the brand new airliner that suffered
two fatal crashes within a few months of each other. The autopilot in both crashes failed, seized
control of the plane and dove it into the ground, killing all on board. After a year, the cause of the autopilot
failure is known, fixes have been made, but the aircraft (and Boeing’s very
survival) are still grounded. The 737
MAX is Boeing’s bread and butter aircraft.
It’s the single aisle jetliner that does most of the flying. They were
cranking out 57 a month ($100 mil apiece).
Production of all of Boeing’s other aircraft was only 20 per month.
FAA is still
paralyzed with fear of another 737 MAX crash which would reflect badly upon
them, and so they are slow walking all the paperwork. The Corona
virus epidemic has caused meetings to be replaced by teleconferences slowing
matters still more. Much more of this,
and Boeing will have to declare bankruptcy.

British history via U-tube.
I watched a couple of decent, lengthy U-Tube presentations by “The
Histocrat”. The first one talks about
humans moving into Britain
a million years ago. Over the last
million years Britain
has suffered several ice ages severe enough to drive all the humans out of Britain,
and as many interglacial periods were the forests and the game and the humans
came back. With both the ice ages and the
interglacials lasting 10,000 years or more.
Used to be, they only wrote about humans settling in Britain
after the last ice age went out 10,000 years ago. Apparently they have discovered a couple of
sites in Britain
that are much older since the last book I read was written. They failed to describe just how these older
sites were dated. Carbon 14 dating only
works back 30-40 thousand years. A
million years is too old for carbon 14 dating.
They did discuss
the seas breaking thru the straits of Dover,
creating the English Channel and cutting Britain
off from the Continent. And sinking
Doggerland. They were a little vague on
just when this happened, and after it happened how did humans get across the
Channel and onto English soil? No
discussion of when early humans, especially Heidelberg man and Neanderthal man
might have developed boats. It doesn’t
take much of a boat; the Channel is only twenty miles wide and can be crossed
in a birch bark canoe in good weather.
The second one,
which started up automatically after the first one finished, picks up the story
around 8000 BC with the Beaker Folk. It
claimed that DNA evidence shows a turnover in British population with the
appearance of Beaker Folk graves. They
fail to describe how this DNA testing works and how many samples of DNA going
back before 8000 BC they have. Some
discussion of introduction of copper and bronze into a flint using late
Neolithic Britain. The author clearly
knows little about metal work, he describes bronze as “hard”. It isn’t very hard. Flint
is much harder than bronze. Bronze is
tougher than flint; you can make a bronze sword that works. You cannot make a flint sword; flint is
brittle as glass and would break the first time you struck anything with it. The author makes a big deal over copper versus
bronze. I don’t see that, bronze is a
straight forward alloy of copper with 10% tin which gives a metal much tougher
than plain copper. But other than adding
the tin, bronze works the same way as copper does. You can cast it and sharpen it the same way
as copper. A copper smith doesn’t have
to learn much to become a bronze smith.
The author discusses smelting copper from the ore (oxides or sulfides of
copper). Actually copper working got
started with native copper. There used
to be nuggets of pure copper just lying around to be picked up. They are mostly gone by now, but they were
important back in the day. The native
copper can be hammered into shape, or melted and cast into shape, much simpler
that figuring out how to smelt copper from ores.

8 1/2 inches of fresh global warming in May
8 1/2 inches of fresh global warming fell on my deck last night. May is late in the season for snow like this. It ought to push back leaf day if the trees have any common sense.

Cops and Courts should handle Campus Sexual Harrassment
Betsy DeVos, Trump's education secretary , has just released new federal guidance to the nation's colleges and universities. Hence forth they have to allow accused students a little bit of due process before expelling them. Good first step. BUT...
Rape is a serious crime. Used to be a death penalty offense. We have backed off on the death penalty, but it is still a serious crime. I don't like students getting judged by a bunch of college admins for serious offenses like rape. That's what we have police and courts for. And American courts are pretty good on due process, far more so than lefty college admins. When someone complains to the college of campus rape or sexual harassment, the college should offer her (or him) a ride to the police station, and a ride back.

Train buffs for Trump.
Today’s campaign mailing offered a real electric model train, all
painted up as a Trump campaign train. It looked kinda cool. I like Trump and I like trains. I have an HO train layout running around the
walls of the down stairs guest room. I
guessed this trophy model train was HO scale.
The picture showed HO style couplers.
A lot of looking did turn up “HO” in an obscure place in the
mailing. I sort of expected a deal for
the train like this “Make a sizable campaign contribution and we will send you
this cool troy.” No such luck. After reading and re-readng the offer, I
think if you send in the paper work they will bill you and if you sent the toy
train operator (not the Trump campaign!) a check, they will send you the
locomotive. Send them two more checks
and they will send you the two passenger cars that make up the full train. No where did it say how much each check had
to be.
After all the
reading and re-reading of the mailer, I decided NO Sale, and put the mailer into File
13.
