Great article, well explained and not hard to follow.

I just finished reading (and then re-reading, up and down) an excellent article.

https://cosmosmagazine.com/mathematics/some-infinities-are-bigger-than-others

Until about halfway into the article I felt my previous belief on sets being not comparable, not larger or smaller if both are infinite.

"It is tempting to say there are twice as many natural numbers as even numbers. But that’s wrong.

When we say two sets of objects are equal, we put them into correspondence on a one-by-one basis. For example, if I claim I have the same number of fingers as toes, I mean that for every one finger there corresponds one toe, with no toes left over and no fingers left unmatched at the finish.

Now do the same for natural numbers and even numbers: pair 1 with 2, 2 with 4, 3 with 6, and so on. There will be exactly one even number for every natural number. The fact that each series forms an infinite set means the sets of numbers are the same size, even though one set is contained within the other! "

Aha, I thought!! 😃

But... Read on...

"This is best understood by envisaging a continuous line, labelled by equally spaced natural numbers: 1, 2, 3 and so on. There will be an infinite number of points between 1 and 2, for example, with each point corresponding to a decimal number. No matter how small an interval on that line and how much you magnify it, there will still be an infinite number of points corresponding to an infinite number of decimals.

It turns out that the set of all points on a continuous line is a bigger infinity than the natural numbers; mathematicians say there is an uncountably infinite number of points on the line (and in three-dimensional space). You simply can’t match up each point on the line with the natural numbers in a one-to-one correspondence. "

So, the Learn New Thing of the Day is that there ARE sizes of infinities. Owa. 😲

By all means read the article --- it's NOT hard to follow, really well explained and authored by a Uni professor.

@freemo I think it's really good that you are thinking ahead and opening further positions as the site grows.

One suggestion to consider, it would be nice to have someone in the mod team who can read the Indian script languages that are now sometimes originating here, showing in the Local timeline and propagating out.

It would save time and problems if that person could read and see a troublesome post or user before complaints arrive from other instances.

@peeleraja Imagine the correlactions with George Orwell's book if that was chosen. 😼

@moonshine@freespeechextremist.com @11112011 @LennartMathiassen @Lennart@spinster.xyz I can understand that, even without ever having been on a Primark. There's many places that are too much for me too.

But man, those façades are pretty. 😃

@moonshine@freespeechextremist.com @11112011 @LennartMathiassen @Lennart@spinster.xyz moon, I am sure you have reasons to detest the stores themselves, but that is a pretty nice streetscape, architecturally. I like Modern, when well done and not conflicting with other buildings.

@I_Will_Wobble Add Bolivia and you have my full agreement.

First World Problems.

And difficult to repair.

From article above:

"The issue highlights the fact that Tesla is not bound by the same rules when it comes to repair as other auto manufacturers. Tesla is not party to a memorandum of understanding signed by other auto manufacturers in 2014, in which they agreed to sell parts to independent repair shops.

As a result, there are very few independent Tesla repair professionals, acquiring parts to repair Teslas is very difficult, and finding or making aftermarket parts is also difficult. Many parts used by independent repair professionals are salvaged from wrecked Teslas. "

I love the idea of an electric car, but why not keep it simple. WE don't need pie in the sky self driving, with myriad sensors and things that will break sooner or later.

Just make a working electric Volkswgen bug kind of thing (the original, hugely popular model), please.

@iankenway Wow!!

1.87 m flooding on St Mark's. OMG.

Thank for the link, haven't been to The Guardian yet this morning, it's my favourite newspaper.

"The issue is with a flash storage chip called the eMMC that is embedded on a board called the MCU1. According to experts who have studied the problem, Teslas are writing vehicle logs to this flash storage chip so much that it eventually goes bad. The issue has been known in the Tesla community since at least May, when Tesla repair YouTuber Rich Benoit spoke to another Tesla repair professional named Phil Sadow about it in a video.

“Tesla’s got a problem. They create so many logs in the car, they write to [the chip] so fast that it basically burns them out. They have a finite amount of writes,” Sadow said in the video. “When this burns out, you wake up to a black screen [in the car’s center console.] There’s nothing there. No climate control. You can generally drive the car, but it won’t charge.” "

@Karthikdeva @mngrif Nice post!

Interesting things to think about.

@iankenway Nice to see not only her, but the many younger people in the audience, who can start voicing and pushing for their future.

They will be the ones living thru the worse of a possible transition.

@moonshine@freespeechextremist.com @Full_marx That would be wonderful, the big socialnet sites are all manipulating the feeds with uninscrutable algos for their own interests.

@susi123 @freemo Me too. 😄

Grabbed one cup this morning, came to check laptop, and...

Three hours later I drag myself to the table to actually have something more solid. It's been a great morning, so many interesting posts and threads.
