Does this will really reach beyond the grave to allow a husband to control a wife's property? Um... not exactly... https://www.legalgenealogist.com/2023/07/31/power-beyond-the-grave/

I ... am left pondering how this story ended 🤔

Was the value of his estate, once it was under her control, somehow "counter balanced" by attaching a liability/creditor of the same amount to her? Would she be obliged in her Will to have have it treated like any other debts she might owe when she died?

I love this view, it's my favourite part of the Island, right at it's southernmost tip. I can pretty much guarantee it won't be one of his most popular images when we get it into the Gallery tomorrow but it's one that I'd choose - if I were one of our customers that is 😅

Imagine buying a website for 44 billion with a captial B..

...a few months later 50% of that is just gone up in smoke

..there's no one with brains left at the company

and the person doing all this thinks it will be all fixed by replacing the decade old bird logo with something my cat could have made in MS paint

I think this "X" stands for "nuke here"

It's really annoying how the neatest way of arranging aperiodic monotiles with gaps between them seems to be to do it periodically

The spectre monotile, arranged in a grid with a bit of space between each tile.The packing looks tighter.

If you show this to an ordinary member of the public, preferably one who has struggled with jigsaw puzzles, I suspect they might suspect, like me, that this approach of putting spaces between the jigsaw pieces is ... ummm ... unconventional?

One thing that I've noticed about is that its algorithm is feeding up the same type of photos that are popular on Instagram. They are the highly-styled images that produce a peak shift effect.

Those types of supernormal images tend to evoke a unnatural emotional response. Often it is a response that drives high engagement, but the effect can produce the opposite response as well.

For me, it drives a high cringe response.

RobertJackson58585858,
@RobertJackson58585858@masto.ai avatar

@bryanhansel

That cringe response ... I've become aware of it more and more. Esp anthropomorphised animal photos and enforced eye contact. In both still and moving images.
Now formalised as " I don't like my emotions being manipulated".
Thank you for explaining the mechanism.

One of the biggest habits that humanity has to kick is that of seeing a human-free space and assuming it’s worthless/empty unless we fill it up with something. It’s happening with plans for the ocean, deforestation for “development”, talk of delivery drones filling the future sky, cube sats that will hide the stars. This “space” is the planetary engine, and it’s incredibly valuable NOW. doing all sorts of things that keep us alive & enrich our lives. We should protect it.

We see the conundrum when we are fortunate enough to have a garden where others have been before, trying to undo their projects, removing bricks and concrete and rusty metal ... But to where does this waste go as we try to recreate what was there before?

In math there's an ordered hierarchy of concepts: stuff, structure and properties. This is because categories have 3 things: objects, morphisms between objects, and equations between morphisms. But we see it in the usual form of math definitions, like:

"A group is a set (that's the stuff) with some operations (that's the structure) obeying some equations (those are the properties)."

To build a group we start with an object in the category of sets - that's the stuff. Then we give it some operations, i.e. some morphisms - that's the structure. Then we impose some equations - those are the properties.

These ideas let us talk about how much a forgetful functor forgets. There are 3 main options. Some functors forget nothing at all. Some forget properties but not structure or stuff. Some forget properties and structure, but not stuff. And some forget properties, structure and stuff. We can get more fancy than this, but this is a good place to start.

Let me say all this more technically, since the point of this junk is that we can make it all precise and prove theorems with it.

Thank you. The 80 20 rule just kicked in with that quick overview/gross simplification :)

It intrigued me that we had the 1st, second and 3rd isomorphism theorems taught in separate courses on groups, rings and modules in the 70s but no one seemed to try to join the dots.

I sense dots being joined 50 years later.

Metaphors in science - know any?

I’m fascinated by the role that metaphors play in scientific discovery. Like Darwin’s “tree” of life. When we shift how we think about what we’re working on, sometimes it inspires us to see it in a whole new way that clicks.

Know any good accounts of metaphors in science - others or your own?

Double entry book keeping and the notion of "balancing the books" ... Every single transaction has twin aspects ... Its debit Dr and its credit Cr ... Both have to be recorded in the books of account to get the books to balance ie as if a pair of scales.

Obviously there is scope for error but the types of error are very well documented!

Oh, yes, debit Dr is the side nearest the window if you write right handed.
