The Nineteenth Byte

At the orchard I worked at they had a giant cherry tree and a giant plum tree and we would get put up on a front-end loader that had a fence around the bucket and pick from there, it was a bit sketchy xD

Mr. Xcoder

At most

Christopher

@Mr.Xcoder Nice, makes picking much simpler

Mr. Xcoder

@Christopher Indeed

Christopher

@StepHen A bit :P I like doing stuff like that

Mr. Xcoder

5:07 PM

Byt they're really small now

Christopher

In washington state we used our tractor to go up high and pick berries over a fence

Mind you it was a bucket, as in for digging (front end loader)

Mr. Xcoder

Unfortunately a few of them died because of the bad weather

What is the vertical axis of a graph called in English?

@Mr.Xcoder not super relevant, but english.stackexchange.com/q/56472/222219

Mr. Xcoder

"abscissa" and "ordinate" was what I was looking for. Thanks

Step Hen

5:51 PM

@Mr.Xcoder Oh, OK. Just so you know, most people will have to look those up :)

Mr. Xcoder

They're called "abscisa", "ordonata" here, I guess it's borrowed from either English, French or Latin.

AdmBorkBork

for what it's worth, I've not encountered the word abscissa until just now

Mr. Xcoder

@AdmBorkBork TIL kind of moment?

Step Hen

@AdmBorkBork Yup, same. Google says it's from Latin

AdmBorkBork

I guess. It says "rarely used" so it's probably archaic

Mr. Xcoder

5:53 PM

It's highly used in Physics in the 7th grade :)

(here, at least)

AdmBorkBork

Not in the US, in my experience, and I was a mathematics major in university

Step Hen

@Mr.Xcoder In English you'd just say x-axis, y-axis, and z-axis, no one would know what abscissa is
