Day eleven of the
George Orwell Tea Challenge and, um, I have not drank any tea today! Our group usually takes tea at 11am and has a morning meeting. However, I was refilling liquid helium into the cryostat at the time and could not leave it alone. Yesterday, however, I took the advice of
xirpha,
polyfrog and others... and began heating the cup before making my tea in it.
Thus far, I have learned two things from the tea challenge:
One: I have learned that far more people on my friends list care about this -- and comment on it -- than I ever would have imagined.
Two: I heave learned that I must be some sort of barbaric pre-Norman savage, as I really do not taste any great difference when I do things like heating my cup or pouring the water while it is still boiling.
Three more days to go...
Yesterday afternoon, on my lunch break, I took a walk and ran some errands. On my walk, I made my way down to The Bear, which is the pub referred to in yesterday's entry. Obsessive compulsive? Me?? Nah!
What I learned, however, is that the background to the comic that I posted is fictional. Nowhere is there a building like the one seen there that has a line of sight to the pub. I was crushed... but I got over it.
Last night,
cheshcat and I went to see the
British Shakespeare Company perform
As You Like It in the Wadham College Gardens.
The BSC is not to be confused with the
Royal Shakespeare Company, whom
cheshcat have seen several times in Stratford; nor are they to be mistaken for the
Oxford Shakespeare Company, whom I have seen perform at Wadham College before with
cheshcat (
Midsummer Nights Dream, 2007) and
resourceress (
Taming of the Shrew and
The Importance of Being Earnest, 2006). I seem to be collecting Shakespeare Companies.
In any case, the BSC is specifically an open air Shakespeare company. Open air theatre is very popular in England in the summertime, or in times that purport to be summer (like now). Of course, with outdoor theatre, the weather becomes a factor... and, indeed, last night was both windy and had intermittent bouts of rain. However, the actors did a fantastic job, even with the weather acting against them. My only regret is that, because they are in Oxford for such a short time, I will not get to see them perform
Henry V with the same cast.
Speaking of cryostats, as I did up above, I want to very happily announce that the current cooldown of the Kelvinox-400 cryostat is the most successful run that I have had to date.
From a personal level, I can say that this may be the first time I have done the entire cooldown myself (since my graduate student, JI, is on holiday).
From the level of the cryostat itself, I can comment that our resistor thermometer has the highest resistance I have ever seen, indicating the lowest temperature that I have ever obtained. The previous record from the dynamic duo of JI & Yours Truly was the cooldown that I started before going to the States. JI reported to me that our thermometer reached about 32 kOhms of resistance. Since we had a radioactive cobalt-60 source inside at the time, we were able to use nuclear orientation thermometry to tell us that the temperature was approximately 6.3mK -- yes, that is 0.0063 degrees above absolute zero! Now the thermometer reads 33.3 kOhms, so I would imagine that we are at five point something millikelvin. Besides a record low temperature, the pressures on the mixing circuit, which cycles the coolant, are very low. This is good, as some previous cooldowns were successful... but had to be cut short from rising internal pressure.
From the data level, which is the most important, I am now collecting data that is worthy of analysis! This is, of course, the most exciting part! Yesterday and today, I have spent more time sitting in front of a computer playing with analysis than I have working with hardware. While I enjoy hardware work, this is a very welcome change for me! It's all about balance!
Speaking of summertime, as I also did up above, I want to go on record as being terribly envious of all of my friends in the States. Why? Because you got to experience summer! Here in England, the high temperatures have generally been in the 60s and it has been perpetually cloudy and rainy. Many people I know who are natives have told me that this has been the coldest and wettest summer that they have ever seen. Lucky us, I guess. Of course, last year we had a heat wave and experienced the hottest July on record. So now I have gotten two extremes in two years. Nonetheless, I am glad that I spent a month in the States, so that I actually got to have a sampling of summer.
Now then, with that said, I should also note that the sun is actually visible for the first time in well over a week. The temperature appears to have broken 70 degrees... and the forecast seems to think that it will stay this way for the weekend. So I will touch wood and hope that maybe, just maybe, there is a little bit of summer on the way. Meanwhile, I sat outside for awhile this afternoon and practiced, on imaginary handbells, the part of the 3 and 4 bells in
Plain Bob Minor. In just over an hour, I have my weekly lesson at St. Giles, followed by our usual rehearsal on tower bells.
Finally, speaking of the weekend, as I also just did, this coming weekend is a bank holiday weekend. Essentially, it is the same end-of-summer holiday that the serves the same purpose as the false Labor Day in the States (except, of course, without the political ulterior motive that accompanies false Labor Day).
Anyway, to celebrate,
cheshcat and I are leaving tomorrow afternoon to spend a long weekend -- plus a couple of vacation days -- exploring Yorkshire. We will be staying in the city of York, but taking excursions outward to see more of Yorkshire than only the one city. I am very much looking forward to this trip! Besides, as a native of New York... isn't it time I finally paid a visit to Old York?
