The Mystery of the Garden Spoon

So this morning this happened:

Underneath the maple tree, a large serving spoon has appeared.  It is not ours. This is not a place people walk, irrespective of whether they drop spoons while doing so.  The spot is sheltered from our neighbours by a large stand of bamboo, so it probably wasn’t thrown there (not that our neighbours are in the habit of casually tossing stainless steel serving spoons around).

The bowl is covered with some pale substance, and lightly scratched.

The back appears burned, and more heavily scratched, including a bright pattern that partially dissapears under a patch of what looks like melted metal. .

Did an animal drag it here?  Did it fall from the sky?  Will other burned kitchen utensils start appearing around us?  Enquiring minds desperately want to know.

So a commenter says it’s something dodgy. Should I be pleased I didn’t know that? Should I be worried that they do? :-)

Someone must have hurled it a long way then, as we spotted nothing on our security camera...

Mercury transit overcast Monday

So, would we see the transit of Mercury?

A little after the time of first contact, the sky was quite cloudy, with the sun hiding.

12:58 GMT, looking south

But the clouds were moving quickly, and there were blue patches.  Then around 2pm, the sky started to clear a bit more.

14:05 GMT, looking south west: blue sky!

lining up the telescope (note the existence of shadows)

We attached a solar filter to the front of our telescope, so it was safe to look through it at the sun.  But we had a very careful protocol: lining up using the tracking eyepiece (not looking through it), then carefully covering that unfiltered eyepiece before looking through the main eyepiece.

And we saw the transit!  A very small, very black spot, clear against the sun’s disk.  Amazing.  (No photographs of it this time, though: much poorer weather than previously, and no time to waste.)

Then it clouded over again; we got about 5 minutes viewing in total.

14:20 GMT, cloudy again: goodby Mercury! it was grest seeing you!

apricity

I stumbled across a new word the other day (new to me; it's actually old, and obsolete): apricity, the warmth of the sun in winter.

After a mostly very dull and wet October this year, finally we are experiencing some apricity.  It is one of those lovely clear, still, and crisp autumn days (does autumn count for using this word?), and although the air temperature is just a few degrees above freezing, there is warmth to be felt standing in the sun.

sequestering carbon, several books at a time C

My one-hundredth sequestration post!

The latest batch:

The Kagan book is not upside down; the title is printed on the spine in the opposite orientation to conventional, possibly because it is from a German printer?  Is the convention the opposite in Germany?

20 years later

It is 20 years to the day since we moved into our newly-built and actually still-in-the-process-of-being-finished house:

Our house in November 1999; still not actually finished!

We were eager to move in asap, as we had sold our previous house, and had been living in B&Bs for a couple of weeks.  Never believe builders’ schedules, even after adding a couple of months to their estimate, as contingency!

Over the last two decades, we’ve had one major repair: the underfloor heating needed to be replaced due to faulty pipework. (No, of course none of the installer’s insurance, the NHBC construction insurance, or our buildings insurance covered it: when do they ever?)

We’ve made one major upgrade: in January 2014 we installed solar panels on the back roof, which conveniently faces south.  Inside, there has been continual shelf-building over the years, as we had 9000 books when we moved in, and have 14000 now.

But the main noticable change from outside is in the maturity of the garden:

our house today; less of a building site, more of a home

Looking forward to many more years here.

the “customer” is not always right

One way that university lecturers, and departments, are ranked and evaluated, is by student satisfaction surveys.  Such a customer-based model does not inevitably lead to better eduction, however, as students are not necessarily the best judges of what they have learned:

College students think they learn less with an effective teaching method
They don’t even realize they’ve learned more.

While students learned more with active instruction..., every measure of satisfaction was lower.

Personally, I prefer a “fitness instructor”-based model, where the students pay the instructor for improvement opportunites and advice (and these should indeed be as well prepared and appropriate as possible), but they have to put in the time, effort, and sweat.  No pain, no gain.
