Hi Don,
Thank you for your answer, because my language as a chemist is not always well understood.
No, your mind is not at all simple. Quite the contrary.
You describe the same reality as me.
What I wanted to describe, like you but with other words, is how the virus travels through the air, because I am afraid of the virus. I am an old man. For that I had to imagine how these organic corpuscles managed to stay suspended in the air like tobacco smoke. For this, these virus corpuscles must be enclosed in a fog, even invisible.
When there is a humidity of 70%, we do not see the water vapor. However, these tiny droplets (nano) can carry the virus.
This is what worries me the most. The virus is almost in a gaseous state. This is the worst possible situation. It is really pernicious, the worst of all. We see it in London today.
Currently, I am almost under house arrest by the state, with little ability to travel. Of course I can buy food and possibly buy other items. But I can't go to a hairdresser for my hair (I barely have more hair).
It is absolutely necessary to wear the mask like the soldiers gassed in the Yser plain in 1914-1918. The air inlet must be closed off as much as possible from above the nose.

Roger,
The corona virus particles are 70–90 nm in diameter, so they can remain suspended in the air for quite some time.

Hello Professor Warin,

Perhaps this study may be useful to you.

I have been watching the college football national championship playoffs on television the last couple of weeks and have noticed something interesting in the segments between the action. It appears that there are mineral crystals similar to beryl and quartz crystals in the graphics. Don't know why but this is the first time I have seen this and I have been watching football on television for probably 60+ years.

Don

I saw that too, and there were some that looked like ferberite and blue cap tourmaline. The graphic artist deserves some recognition. These were good!

Hi to everybody!
Here in Italy it's strictly compulsory to wear a mask covering mouth and nose, and it's compulsory to respect an interpersonal distance of at least 1 metre. Nevertheless we have at least 300 to 700 deaths per day...
Greetings by Riccardo.

PostPosted: May 27, 2021 10:09    Post subject: I hope that this photo brings a smile  

And, finally, I hope that this photo brings a smile to some faces during these hard times.

My grandson, 18 months old, is really into rocks.....these are his formative years!

My daughter and her husband live in Italy, North of Genoa. Both have dual US/Italian citizenship, with both being fluent in Italian and English. The little one speaks 3 languages, English, Italian and mostly gibberish.

The photo is on a recent trip to the beaches of the Ligurian Sea, near Genoa. :). BOB

Nice.
A great promise for mineral collecting, since that area is very rich in garnets, epidotes, diopsides, vesuvianites etc.
Let's hope he follows in his grandfather's footsteps. That's what I'm hoping about my grandchildren.
And let's not lose the illusion that the new generations are willing to listen to our "gibberish".

Best regards.
Sante

Great, Bob!!!

I also hope that this cute little fellow will follow your footsteps. I know the proud feeling when the very young get involved in our hobby and when they seem to like it. My sons are 5 and 3 y/o and they're already interested in rocks, I hope this will endure! Good to to see that there are more little fellows who might be the FMF community of the future ;-)

Regards
Tobi

Hi to everybody!
Here in Italy the situation is slowly improving, TOO slowly in my opinion. I got the first inoculation (AstraZeneca) on March 14 and I should get the second one next Sunday. Then... let's hope!

Hi to everybody!
Here in Italy the situation has significantly improved from the point of view of victims and hospitalized people, but cases are increasing again, due to the Delta variant. Ok, let's hope it's not so aggressive like the other ones, however I got my second inoculation on last June 6 and printed my Green Pass. My second inoculation was AstraZeneca once again and I had no problem at all. I succeeded in doing my bicycle tour through Europe the last three weeks too, I visited Jachymov, Annaberg, Ehrenfriedensdorf, Freiberg, Lwowek Slaski (despite the mineral show was cancelled) and Lubin. Keep healthy everybody!

Same here in Germany. I got my 2nd vaccination with Biontech some weeks ago and I hope everyone here who wants to get vaccinated will get it as soon as possible. Stay healthy and let's hope that the situation doesn't get too bad again!

Best regards
Tobi
