Today I Learned

[Klystron]

TIL Telluric currents exist, can be used as an energy source and to map subsurface Earth. Thanks @Baluncore .

I knew Tellus is Latin for Earth and that we ground EM circuits and send and receive VLF and ELF signals through the Earth. I was taught or I assumed that the many references in old books to geomantic or telluric currents talked about some spiritual or supernatural essence or described the Earth's geomagnetic field.

Fra Junipero Serra mentioned telluric currents guiding his mission site planning in California but I assumed he meant compass readings. I need to rethink the meaning of many old manuscripts I read years ago though I no longer have access to those libraries and no longer understand much Latin and Spanish due to age. Live and learn something new each day.

TIL that I'm not the only one who misreads words (didn't really think I was, but this confirms it)

TIL the title of the PF science fiction subforum is "Writing and Worldbuilding". I read the title as "Word Building"

I still read it as Word building.

My problem is that every time I see the word "lawmakers" I read it as "lawn makers" in the split second before my brain recovers and thinks "crap ... did it again!"

That's understandable. Both of them involve the use of a lot of fertilizer.

[Astronuc]

TIL a few things:

A 2013 sniper attack on an electric power substation in Northern California, which caused more than $15 million in damages and destroyed 17 transformers, led Idaho National Laboratory researchers to develop a novel protective solution.

Currently, the U.S. imports about 85% of its high-voltage transformers from other countries. These large, custom-built devices cost $2.5 million to $10 million dollars each. With limited supplies, expensive raw materials and fabrication times of more than a year, the loss of a single piece of equipment could prevent reliable power from being delivered, creating a risk to national security, economic stability and public health.

poor dental hygiene can lead to acne

I had 3 - yup 3 - cavities and was recently breaking out in my face. After getting a cleaning and the cavities filled, I'm noticing a cleared up complexion.

The bad bacteria all encrusted/living/multiplying in your mouth from bad dental hygiene can get into your skin tissue as well and lead to breakouts/acne.

My date will thank me for this. Note to self: get dental cleanings more often. This was my first time back since COVID (i.e., it was 2 years since a cleaning).

Russia has about 11 million people with relatives in Ukraine. Can't wait until letters start showing up in Russia posted with these stamps.

Wow, those are expensive. I scrolled down and finally found one for $10 only to discover that shipping was an additional $170.

Reading 1493, the excellent book on the Columbian Exchange. Natural rubber remains critical for medical and industrial applications. While native to Amazonia, commercial production of rubber trees in the Americas stopped in the 1930s due to a native fungus. Asia today produces most of the world's Rubber in a monoculture that is very susceptible to the blight - a few spores from Brazil crossing the Pacific could lead to a global economic disaster

Blight killed all the banana trees in the Americas in 1900 or so. They recovered by importing bananas from the Cavendish hothouse in the UK. Yep, the same gravitational constant Cavendish family. They are "dwarf bananas" because the tree is smaller even though Cavendish bananas are giant.

Cavendish are my fave bananas even though they don't have much flavor. I don't like the taste of the original bananas, so bland is better.

I'm officially quitting on human nature:

https://www.edmunds.com/car-news/toyota-considers-ev-with-simulated-manual.html​

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 )

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".

They switching the LHC on again?

I wish I could place a substantial bet that they don't find any (dark matter).

 

[Oldman too]

I wish I could place a substantial bet that they don't find any (dark matter).

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.

 

[Tom.G]

I wish I could place a substantial bet that they don't find any (dark matter).

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.

Last resort, your local bookie.

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.

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).

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 about a tree that becomes a fountain.

 

[strangerep]

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

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.

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.

 

[pinball1970]

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
