I don't have xenophobia, I just have negative idiototropism. (WTF would someone with xenophobia be doing living in a foreign country where he doesn't speak either of the languages, one has to ask. Being hair-brained! My god - he's got it, that's the explanation for everything!)

Is that sweet or salted?

Its neither.
Its bitter
You are just plain bitter with yourself

Foreign country? Probably because you couldnt make it in your own.
And this is not only bitter but acidic

I wandered out into the nice warm sunshine this lunch time wearing a short-sleeved T-shirt and a thin sweater that's not even remotely wind-proof.

Certainly not what I'd call bitterly cold. I've been colder in January in the Canaries.

Ever wondered why the zero-point of the Fahrenheit scale is set at its particular temperature?

Zero Fahrenheit is the minimum temperature at which a NaCl / H_2O mixture is in equilbrium with liquid.

0F = -22.22222...C

A quick check of http://en.wikipedia.org/wiki/Fahrenheit seems to have alternate reasons for 0 F.

I personally like F for use in describing atmospheric temperatures. 70 is about ok, 80 is not comfortable, but ok, 90 is hot, but not horrid, 100 is miserable, 110 is scorching, 120 is very bad, 60 is cool but not a problem, 50 cool (or cold if one is sitting around), 40 is Cold, 30 is Freezing, 20 don't even want to think think about. 65-75 is a good range.

Winter? This year it happened to be on a thursday. ;)

Here in Austria we didn't have any winter yet (except a little bit of snow on 2nd and 3rd november). Currently (6:26 CET in the morning) the temperature is +14.3°C here!! (normally it should be below 0°C at this time)

°C = (°F − 32) ÷ 1.8

0ºF = (0-32)/1.8 = -160/9 = - 17.777777..... ºC

You are bang on ATH and Xilman is once again in a world of his own.

Using the same formula I've always held it as C/5 = (F - 32)/9

When F = 0 , C = (-32/9) * 5 = -160/9 = -17.77777.....C

One can check it by putting C=100* correponding to F =212* the boiling point of pure water

You are quite right and I was wrong.

I'd remembered the salt&water explanation for the zero point of the Fahrenheit scale, something I was taught at school many years ago now. I then miscalculated 0F into Celcius and wrongly matched that result with the -23C quoted earlier in this thread.

I've already admitted my mistake.

Are you yet ready to accept that the earth is warmer in the northern winter than in the northern summer or are you also in a world of your own?

Default back to weird weather

I've just been told - in e-conversation so theres no source I'm afraid- that New Zealand has had the coldest December on record. London meanwhile continues to be unseasonably mild.

London is probably a bit milder than Cambridge. I have several Geraniums still flowering; some have more buds coming.
