Hallo Leute,
da es auch ein Interessantes Thema ist möchte ich euch ein Artikel empfehlen wo man was lernen kann über Blumen und Blumenhocker, hier ist den Link und viel Spaß beim lesen

It is told, that the risks of infections in nurserys is way lower, than in other institutions

The risk of serious infection in nursery populations seems to be low because young kids seem not to develop severe symptoms (if any) but the virus is always happy to spread to asymptomatic carriers who then take it home to their families. The best carrier is the one who doesn't know he has the disease, and is hugged and kissed by lots of adults.

The small ones are supposed to be socialising and learning from other people. They absorb so much information this way. Especially in their life-phase where they develope so quickly.

And who better to learn from than their parents and elder siblings? What useful skills, behavior and language can a baby learn from another baby? Nurseries are dumping grounds for kids who get in the way of their parents earning money.

I see the reasoning behind the first poin. And you might be right. But i can`t in any way agree on the second one...
Maybe that is the way you see it, but i think it is pretty obvious in these days, what happens to people when they aren`t in an environment where they are able to socialise. Maye you misunderstood me, because i didn`t try to imply, that children learn ONLY from nurserys. I do also think, that the main teachers in a Childs life are their parents. But the social life is a huge aspect aswell, and it is getting damaged big time.
Now i can`t give a certain solution to this problem. On the one hand, some instituions (like nurseries in this case) should be closed to minimize the infection rate. But on the other hand, it is a crucial part of discovering how life works, and getting to know, that there is more to it than just "mommy" "daddy" and maybe "nanny".

Once again, I can't go for an unnecessary drive in a car, can't play golf, can't go and see someone else in their garden, yet I can go indoors to a church, can send a child to nursery, and can order from the internet businesses with industrial sweatshops. It was the same a month ago, during the last lockdown, which strangely enough failed to dent the spread of corona. It is a complete waste of my time, and is patently unfair. At least this time they have bothered to shut the schools.

I would like to refer to the aspect you mentioned about sending children to nurseries.
I come from Gemany, and nurserys were shut down due to high infection rates. Believe me, closing nurseries should be one of the last options. A lot of parents here in Germany are in a crisis, since a lot of them can`t go to work because they have to babysit their children. And a lot of people who would love to hire a nany can`t afford it. Not every company allows or is suitable for Home Office, which leads to a lot of adults being unable to work to sustain their families.
I am by no means trying to be insulting here, but it just lit a spark in my heart.

But the infection rates came down quite drastically compared to the UK did they not ?

Well I can agree, that the Numbers went down way quicker in comparison to UK.
But I wouldn`t necessarily explain it with the shutting down of nurserys. It is told, that the risks of infections in nurserys is way lower, than in other institutions (at least in Germany even from the national television). Of course, most deffinetly prevents some infections, that is without doubt. But the damage the families take is just too big. For parents AND the children.

The Environment / Re: How could you stop the earth's poles from warming?

« on: 19/02/2021 10:30:40 »

Well i`m not sure whether it is important, how warm or cold the poles were 500 yrs ago...
Of course that is an interesting topic, but not necessarily for this thread
The problem, as suggested by the graph from Bored Chemist, is quite dire and lies in the present.

The Environment / Geoengineering - Yes or No ?

« on: 18/02/2021 17:36:15 »

Hi everyone!

I recently found this other post on this forum mentioning cooling down the hottest places on earth, instead of cooling down the poles to their previous, more "stable" temperatures.
Since i am a big fan of experiments in general, and geoengineering itself would be a one big experiment, I was interested about your opinions on this topic. Is geoengineering a good idea?
The whole thing sure seems very interesting, but also hella theoretical and risky.

The Environment / Re: Best location for geoengineering ?

« on: 18/02/2021 17:25:46 »

Hi!
I recently watched a Kurzgesagt video on YouTube, that adressed this topic.
One of my favorite methods of Geoengineering they mentioned, was fertelizing the oceans with iron, so that the growth of algae would be increased. Why the increased growth of algae would be benefficiary, is pretty self explainatory.
They did mention other methods aswell, but this one sticked with me the best. I would recommend it, if you wanna look more into this topic

Physics, Astronomy & Cosmology / Re: Why is light bent whent it passes a massive body in the space?

« on: 17/02/2021 10:41:35 »

I am also no big expert on this topic. Just an enthusiast as to how everything in life works. Furhtermore trying to just seek out a logical explanation for almost everything in life 
I recall seeing in a couple of videos on YouTube that light ist bent by objects.

Is or isn't? 
also, one needs to be careful when getting information from YouTube videos, as there is a lot of incorrect information out there.
as far as light direction being changed by objects.  There are a few ways this can happen:
Reflection.  Light bounces off the object.
Scattering. light is effected by passing through an object or medium by interacting with the individual particles within it.
Refraction,  The light path direction is changed by passing through the boundary between mediums of different refraction indices. (or through a medium with a changing index of refraction.
Defraction. Light path is spread by passing through a slit or close to the edge of an object

With all of these, with the exception of reflection, the degree of path change is dependent on the wavelength of the light.
Thus, they would produce a measurable separation of the component colors in white light.

With gravitational lensing, you would not see such a separation of colors. The path of all frequencies would be changed equally.

This is where all these alternate explanations for the bending of light as they pass the Sun or distant galaxies fail.  These other suggested mechanisms would produce other noticeable effects in the light that we just don't observe. *

* Plus, in the example of our own Sun, it would be take the greatest of coincidences for these effects to cause the exact amount of bending as predicted for gravitational lensing.

Thank you for the heads up!!
That does shed some light on this topic 
About the YouTube stuff: Yeah, I know... a lot of Information is kind of meh and not percise. I tend to watch VSauce a lot. Their channels seems to be trustworthy. At least I don`t recall getting any shady/false Informations from there.
Maybe someone could recommend other trustworthy YouTbe channels? Love to spend some of my free time like that.

Really love some of the videos that I found over here. Wasn`t quite what i was expecting when i logged on, but i must say I was supprised in a positive way.
Just fascinating seein, how Science can be formed in a way for humans to listen to. What people are able to do becomes more and more amazing each and every day!!!
