Today I Learned

Today I learned that cleaning a white hat can be done with bleach cleaner, but it’s important to rinse it before wearing it again. I also discovered that "oyster veneering," a woodworking technique from the late 1600s, is experiencing a minor revival despite its labor-intensive nature. Additionally, I learned that the factorial of 23 (23!) equals 25,852,016,738,884,976,640,000, which interestingly has 23 digits, a unique coincidence among factorials. I found out that medical specialists often spend less than 10 minutes with patients, and that watching TV can contribute to weight gain. Other insights included the fact that a kiss can transfer around 80 million microbes, and that bureaucracy can sometimes hinder employment opportunities. The discussion also touched on various trivia, such as the emotional sensitivity of barn owls and the complexities of gravitational lensing around black holes.

How it would work​

Toyota's stick-shift EV would feature a pair of driving modes, one with a "traditional" shiftless EV driving experience and another utilizing a physical clutch pedal and shifter. The patents describe tactile feedback in each element, down to vibrations in the clutch pedal when it's "slipping" as the clutch pedal is released. Toyota's team noted that in the "manual" driving mode, the power output would be modulated to mimic an internal-combustion engine. The documents describe this as an effort to address the concerns of drivers who want the "driving feel" a manual transmission offers.
What a waste of time, energy, and resources when there are so many more important problems to solve.

I'm curious how well the "tactile feedback" will simulate a hard launch when the "Clutch is dropped".
Wait, never mind, I'll stick with a real manual. (TY ):rolleyes:

I can't find an exception to that statement.

Reminds me one prototype of the Model T which featured a 6" gap in the windshield. This allowed the driver to crack specially made whip on the hood. A pressure plate attached to the throttle would then make the car speed up by a small amount

Yea, I wonder if it will just turn off if you "stall" the engine and make you push the on button again? You know, like a real 20th century car.

Maybe they should just give you one of these to entertain yourself after you tell it "take me to the airport".

I checked with the Vegas bookies, nobodies giving odds yet. If you find someone to take that substantial bet, I'd like a piece of the action.

Try the folks in Las Vegas, word is that you can find Someone to take any bet.

If that doesn't work there is always Macau. :rolleyes:

Last resort, your local bookie. :rolleyes: :rolleyes:

Finding someone to take the bet is probably easy. Finding someone who will also pay up when they lose is trickier. (Weaseling out, or murdering you if you're too insistent about it.)

I could not find anything on CERN site it was not meant as a joke. If you click news there was something about Brazil!
Anyway it is going ahead so we have Webb AND the LHC looking at the very large and the very small this year which is exciting.

Happy DNA day!

On the day, April 25, in 1953 (the year I was born!), an article describing the structure of DNA was published in Nature (the journal).

Revel in the greater awareness that has come from this discovery.

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.
