Kind of embarrassing, I had seen the name ' Eswatini' and thought it was the name of a web-based company. It turns out it's the name of the recently-renamed African country of Swaziland.

I figured £5 a week is worth it for what it can do.

And what, specifically, can it do?

 

[skyshrimp]

And what, specifically, can it do?

I use it several times a day. In fact, I would not like to live in a world without it. It’s just the little things.

I was cycling recently and saw a flower I wanted in someone’s garden. I took a photo and asked AI what it was. It answered instantly with the correct ID and how to care for it.

It has helped me immensely regarding the care of my tropical seedlings. It’s brilliant. Like having your own Data from Star Trek. I love it!

My mother asked me to evaluate her antiques she wanted to sell. I uploaded photos to AI and it told me exactly what it was and what it was worth within seconds. After uploading several images or using it too long, it downgrades to an older model for hours unless you upgrade.

I know it makes mistakes, but it points you to the right direction. I also now have access to the Sora AI model so I can generate realistic AI videos.

It’s literally God for atheists. All hail the AI Singularity.

All that for £5 a week?

What can I see of companies that send emails where they give you the option to unsubscribe, which...requires you enter your email? Scams or just poorly designed? Both?

I hate my autocorrect. I type "surjective" without re-reading it and it makes "subjective" out of it. But that damn thing has no problem accepting comtraproductive or geberator when I miss the "n".

That's because you would not want it to autocorrect "bigger"!

Ok, so you told me you would charge me unless I said I didn't want a renewal. So I'll go to your offices and spit in your face, kick you, etc., unless you explicitly tell me not to.

I wish sig figs were also used rigorously in synthetic chemistry. The analytical crowd knows how to report values, but synthetic chemists will write "Then [reagent] (40 wt%, 6.23 ml, 5 mmol) was added" like there isnt a host of issues with listing those numbers as dependent of each other.

In reality, their calculators probably calculate 5.000 mmol (or something) but moreover they use a precise ml volume that they measured... How? Most graduated cylinders only allow precision of the first decimal and thats usually with an explicit uncertainty. Micropipette maybe? Also most commercially bought solutions that are listed in wt% are usually not as precise as you'd think.

Your school is so good even the cylinders graduated.

I hate English. Autocorrect wants me to write webserver as web server, but if I apply it to web sites, it insists on one word, <grrrr>. Why is vector space two words and eigenspace only one?

And what is it with the hyphenation? Are there rules, or is it an on-the-spot decision?

Do I need to put an insulating barrier between my pressure-treated woods and my natural woods to prevent galvanic corrosion?

The question is probably more about different levels of humidity and possible mold.

I've found to deal differently at different times when I use the same word.

Isn't that because website is a word and webserver is not?

eigenspace is a word (because Germans hate space characters) and vector space is not German?

Something slightly related which has always amazed me (assuming of course that I've remembered it correctly): If you roll a ball over the surface another fixed one of the same radius without slipping or twisting, the orientation of the rolling ball only depends on where it is, not how it got there. The set of relative orientations of the rolling ball is equivalent to aligning it first with the orientation of the fixed ball then rotating the rolling ball by a half turn about the radius through the point of contact (so the moving ball has the same orientation at opposite points on the surface).

I ran into this student from the beginning of my former adjunct days that I had impacted not so positively. I was writing on the board and a fly was buzzing around me and I couldn't find a way of getting rid of it, until at one point, I just pounded the fly dead into the blackboard. This did seem to traumatize her to the point I remember her just looking away when I directed my sight in her direction. She also seem to avoid me if she saw me outside of class. Weird story.

Did you include Malliavin Differential in your pantheon of derivatives? Or Frechet?

Fréchet and Gateaux in Part 2, and material in Part 4, also known as

Euler operator
advective derivative
convective derivative
derivative following the motion
hydrodynamic derivative
Lagrangian derivative
substantial derivative
substantive derivative
Stokes derivative
total derivative

but I avoided stochastics.

Maybe I could do some myself into an insight. Though ito is more of an actual net infinitesimal change and not a rate of change as a derivative.

I think we could need quite a few insights from stochastic, and statistics in general. I have observed that they are a very frequent topic on MSE, and we are not specifically good at it, maybe with the exception of @Dale. (I only had a B-C in my exam on a Rosenmontag.)

The different perspectives alone (Bayesian or not, the various common distributions, measure theory approach, stochastic analysis like the Malliavin calculus, statistical tests) would deserve an article, not to mention the standards like the laws of large numbers or the $\chi^2$-test, and as we are a physics website, probably Brownian motions, time series, and Boltzmann.

This field is large!

Another win in my quartel against ETS: the ratio of the area of a circle inscribed in an equilateral triangle is fixed. Thus knowing the radius of the circle is enough to know that of the inscribing triangle.
