In summary: Today I learned that Lagrange was Italian and that he lamented the execution of Lavoisier in France during the French Revolution with the quote:"It took them only an instant to cut off this head and a hundred years might not suffice to reproduce it's...brains."

Even mild Covid is linked to brain damage, scans show​

https://www.cnbc.com/2022/03/07/even-mild-covid-is-linked-to-brain-damage-scans-show.html
During at least the first few months following a Coronavirus infection, even mild cases of Covid-19 are associated with subtle tissue damage and accelerated losses in brain regions tied to the sense of smell, as well as a small loss in the brain’s overall volume, a new British study finds. Having mild Covid is also associated with a cognitive function deficit.

These are the striking findings of the new study led by University of Oxford investigators, one that leading Covid researchers consider particularly important because it is the first study of the disease’s potential impact on the brain that is based on brain scans taken both before and after participants contracted the coronavirus.

TIL... something horrible. Apparently, in Australia, every 11 days on average, a woman is killed by someone she knows. :cry:

I knew domestic violence was an increasingly serious problem, but the mainstream media reports only very few of these murders. I guess it's now so common that it doesn't rate (for them) as news. :oldmad:

So now I'm wondering how this statistic compares to other countries...

I don't believe that such a quantity of water comes through roots. I say the tree is hollow and acting as a pipe.

2/week is the stat I've heard for the UK. Given our population is about 70m to Australia's 26m it's a comparable per capita rate. It passes similarly largely unremarked. Another stat I've heard is that it accounts for around 25% of murders of women.

It's worth noting that you said "someone she knows", but you could say "a man she knows". I'll bet you at most one of your 30-odd per year partner killings was by a woman, and probably none.

I am not sure how robust the data is but everything I have read on this is you are most likely to be killed by your parents than a stranger regardless of sex if you are a child

https://theconversation.com/men-and...-numbers-and-we-need-to-understand-why-153527

More likely to be killed by an intimate partner if you are a woman

https://www.vpc.org/studies/wmmw2015.pdf

Physical abuse is 60% M 40%

https://www.theguardian.com/society/2010/sep/05/men-victims-domestic-violence#:~:text=These figures are equivalent to,abuse and 600,000 male victims".

These numbers are going to vary by country culture and decade. for @strangerep

Jean Struven Harris (April 27, 1923 – December 23, 2012) was the headmistress of The Madeira School for girls in McLean, Virginia, who made national news in the early 1980s when she was tried and convicted of the murder of her ex-lover, Herman Tarnower, a well-known cardiologist and author of the best-selling book The Complete Scarsdale Medical Diet.

During the last several days I have been learning the Lebesgue integration theory for functions with values in a Banach space by S.Lang's "Real Analysis". The narration is pretty nice and clear.
Since the construction is very general it does not rely on accidental things like an order in the space of values. This straightens the structure.

Sounds risky on first look, the links explain it pretty well though. The hackers are already at a work around for this unless I miss my guess. Still it is an improvement over the current system, we'll see soon enough.

I have hundreds of passwords. If I haven't been back to somewhere in over six months I have to reset it.

Not mine yet.

I confess, I did not like it at first - having to have a second device handy. But now I always have my phone, so it's not such a hardship.

Sorry, I should have specified, that only applies to bank employees. My granddaughter works in a bank and it's their default authentication for all employees. Seems to work great for them. There seems to be a fallback recovery method should you lose your phone.

I'm not even using it yet personally but I'm rarely without the phone handy, I'll be glad to get rid of password authentication.

CS Lewis was actually Irish and had a hatred of the English for a while after coming to England.
He was an atheist and interested in mysticism before converting to Christianity.

John Von Neuman was a very impressive individual! Too much to mention but one thing I noticed reading his wiki page was he had a guard over him while he was dying at a military medical centre.

He was medicated and military was worried about him talking about US secrets as he passed.

Supposedly, the only question Hilbert asked Von Neumann at his Ph.D. defense was

"In all my years I have never seen such beautiful evening clothes: pray, who is the candidate's tailor”​

I can not explain that but I feel something not good to pass in such a way.
