It is also the same if you turn it upside down (using the correct font).

Yes, crissdee, that’s the one. For clarity, I meant rotating it 180 degrees.

For still greater clarity, you meant rotating it 180 degrees about an axis perpendicular to the plane in which the numbers lie.

The definition of "upside-down", when applied to planar figures, still confuses me from time to time. I generally use it in the same sense as above (rotated by 180 degrees in the same plane). However, I remember once referring to the mathematical ∃ symbol as an "upside-down E" and getting puzzled looks from people who claimed that an upside-down E was the same as a normal E (i.e. rotated about a horizontal axis). It isn't as far as I'm concerned.

I get particularly confused by the "upside-down Union Jack". If you take a Union Jack as correctly flown, and rotate it by 180 degrees in the same plane, it's still correctly flown. You have to turn it over to fly it "upside-down". In my way of thinking, that's "back to front" rather than "upside-down".

Is there a generally agreed definition of "upside-down", or does it have to be inferred from the context?

I would call that symbol a "back to front" E, rather than upside down. with the flag, you're right about it looking the same rotated, but I would call the "flipped" one "upside down".

It is of course a "back to front" E as well, because E has a horizontal axis of symmetry. Maybe an entire word would make the distinctions clearer:

(1) HOUSE - normal
(2) ƎƧUOH - reflected in vertical axis
(3) HO∩ƧE - reflected in horizontal axis
(4) ƎS∩OH - rotated

I would call (2) "back to front" and (4) "upside down"; I don't have a special term for (3). Would anyone call (3) "upside down"? What would they call (4)?

That seems to be the usual terminology, but it corresponds to (2) or (3) rather than (4).

A new study has been published showing the effects of respiratory treatment on mice and pigs using oxygen-carrying liquid delivered through the anus.

Takanori Takebe from Tokyo Medical and Dental University published a study in the journal Med, saying that if such a method of oxygen delivery can be successfully developed for humans, it can be used as an alternative to ventilators, which are obviously in short surply due to Covid-19.

For me however, the quite interesting aspect of this is the name for this method. It is called the "enteral ventilation via anus" method, or EVA method for short. The name is a reference to one of the most famous of Japanese anime series, Evangelion. The series follows teenagers who are made to pilot giant "EVA" mecha, and part of the process of operating them is filling the cockpit with a breathable liquid which the pilots have to consume.

I prefer the video explanation - 8 and some weird combination of reverse polish notation and.... - well, if you smoke the right stuff it makes stuff

Different strokes, I found the table at the bottom much more informative, but then I'm not a good video watcher when it's info I'm after.

Sigh.
Again.

It is, but nowadays everyone ignores the "times 20" origin and we're just left with somewhat odd names for the tens above 40. Once you're past the "learning the numbers up to 100" age it's fine.
Nobody really cares. Except the Swedish. It confuses the **** out of the Swedish.
