Reply to comment by Neither_Ride3473 in A new study suggests that too much screen time during infancy may lead to changes in brain activity, as well as problems with executive functioning — the ability to stay focused and control impulses, behaviors, and emotions — in elementary school. by Wagamaga

I did. We used to watch Cocomelon and Have Fun Teaching a lot together; he loved the counting ducks and the ABCs. Part of our bedtime routine was a 3 minute cartoon video of singing Twinkle Twinkle Little Star.

I was wondering if we were giving too much screen time to him, until he recited his ABCs and knew his planets by sight at 1 year old. Little dude's 5 now, and really into Numberblocks. Kid knows almost all of his times tables (still stumbles with 7's and 8's), which is damn impressive amount for a kindergartener and can do powers of 2 up until 1024.

You ask me, I think educational screen time should be studied for beneficial effects of childhood development. Did a treat on my little guy.

I wish this were part of the study... unfortunately, my kids watch alot of TV (23 mos and 7mos). But we are there with them singing songs and pointing out characters and interacting. Now, Disney is very fast paced for kids, unfortunately, but we try no screen time for a little bit each day, and dinner at the table with no screens. Neither of our kids use our phones or tablets, and while the TV is playing they are playing with toys and books which we also play with. Parenting is not easy, and there are so many ways to do it. Not a one size fits all.

Reply to comment by [deleted] in Political views can be predicted by differences in brain activity. Study says political differences don’t just emerge when it comes to how we interpret reality around us; our brains actually ‘see’ different things depending on our politics. by mossadnik

Well we already know that if you are high in conscientiousness in the big 5 personality traits, you are likely to be conservative, and Openness predicts for more left leaning views, this is seems to be before political views are established.

I'd say that it's definitely likely we see the world vastly differently, and that changes our political opinions for sure. Idk if it's a actual biological marker, like different part of the brain develops differently, that seems odd.

I'm actually deeply interested in what enables us to perceive the world. And it seems like we see patterns, which enables us to see stories & objects, which enables us to assume things as good/bad. These patterns and subsequent stories we see, change what we look at. For instance, we assume ppl in the store won't kill us. Or we see the pattern of faces in abstract designs (like the famous martion face on mars). This deeply influences everything about how we perceive the world, so we might be extremely sympathetic to the poor, or maybe we look at the world more rationally. Experiences, culture and so on all help shape this world view, or what patterns we see as relavent, because ofcourse their are infinite amount of patterns to perceive. So it stands to reason that these will significantly have an effect on our political stances.

Reply to comment by thombiro in In Monet's impressionist paintings, that dreamy haze is air pollution, study says by WouldbeWanderer

although not about “feeling”, thats the best theory; as well - again because of tech advancement - oil paint could be bought in in tubes and cheaply, and was also portable; that and the import of japanese pictures changed how the early moderns thought of pictures and representation too.

you see this these changes in painting again with the advent of radio, film, tv and most recently with the adaptation of handheld flatscreen computers

to paraphrase marshall mcluhan: any new medium creates stress on old mediums to change

Reply to New review finds that rocket emissions in the upper atmosphere can affect the ozone layer but are not regulated — Global annual launches grew from 90 to 190 in the past 5 years, and an upsurge in rocket launches may potentially undo decades of work to save the ozone layer by marketrent

Findings in title quoted from the linked summary^1 and its hyperlinked journal paper T. Brown, et al.^2

From the 3 Feb. 2023 summary^1 by the authors of T. Brown, et al.:

>Rockets have exciting potential to enable industrial-level access to near-Earth space and exploration throughout the solar system.

>This makes them “charismatic technology” – and the promise of what the technology can enable drives deep emotional investment.

>The allure of possibility can get in the way of even discussing how to make rockets achieve these aspirational goals without damage. We have to be able to have clear discussions.

>The ozone layer is on track to heal within four decades, according to a recent UN report, but this progress could be undone by an upsurge in rocket launches expected during the same period.

>As we show in our new review, the gases and particulates rockets emit as they punch through the atmosphere could lead to delays in the ozone layer’s recovery.

>Fortunately, the number of launches to date is so small that the impacts on the ozone layer are currently insignificant.

>However, over coming decades the launch industry is set to expand considerably.

> 

>As we outline, rocket emissions in the upper atmosphere can affect the ozone layer but are not regulated. We argue this policy gap must be filled to ensure sustainable growth of the rocket launch industry and protection of the ozone layer.

>The launch industry today relies on four major fuel types for rocket propulsion: liquid kerosene, cryogenic, hypergolic and solid.

>The combustion of these fuels means contemporary rockets create a suite of gaseous and particulate exhaust products, including carbon dioxide, water vapour, black carbon, alumina, reactive chloride and nitrogen oxides. These products are known to destroy ozone.

>A new fuel is methane, which is used in multiple rocket engines under development by major launch companies. The emissions products of methane are as yet poorly understood.

>In the stratosphere, an upper level of the atmosphere where the protective ozone layer resides, emissions linger for much longer than lower down.

>Small amounts of an exhaust byproduct can have greater destructive effects in the upper atmosphere than when close to Earth’s surface.

You can think whatever you want but your opinions unfortunately don't change reality.

How exactly can someone not be an idiot as well as curious and easily occupied? I hate to break it to you but it's extremely easy to entertain a stupid person, not so much with the opposite side of the spectrum.

Providing internet access with privacy allows baby's and young children to find and connect with others that can support their identities and values so that parents are prevented from instilling their own toxic values.
