Thank you for this , makes things more scary but at least a little clearer. But it does make sense. Fully agreed., lets not go there. Paul

I would guess the main difference between1930s and now is we have the internet, but as we have determined little in the way of critical thinking skills.

Interesting artifice so i guess the fear about Trump being president is now rearing its head again only the world (and the us) has changed so much since 2016 (BLM, Pandemic) that the momentum for change is stronger or he will be back as president again. I can understand the removal of the confederate flag , but should we remove(Ban) ALL symbols relating to this including statues,? we need some reminder what happened so hopefully future generations can learn. in the same way as we need to remember what happened in Germany in the 1930s.

A lot of this seems very similar what happened in Germany during the 1930s as Hitler and the Nazi Party rose to power and tried to create a master race and remove anyone who didn't fit in to the Aryan race profile. Of course learning history you see parallels, by rewriting this out of history (or trying to) there is no historical event timeline to make comparisons to., With critical thinking and questioning you can challenge the propaganda. "dark-skinned athletes pushing them out of sport teams" Reminds me of remember the titans (film) but that is based on a true story, I am not going to say too much as I don't want to in inadvertently add in a spoiler. But that was set in 1971 so around the time of Nixon, and as stated earlier post Nixon was about the time everything started to go wrong.

Well the current shooting of a 9 year old girl (white) is hitting the headlines more, very little about the other similar incidents in Liverpool over the past week https://www.bbc.co.uk/news/uk-england-merseyside-62658221 So yeah, getting a proper picture of what is going on is rather difficult, because one news story can dominate so much of the news (1.2 hour programme) it leaves little time for other stories to be covered. Look at the Afghanistan withdrawal in 2021, it dominated the news, at the same time there was a major earthquake in Haiti (I think) which barely made the news, until some arrived in the US as refugees and were apparently deported

Yes I can see that happening here, more and more of our NHS is in private hands via various contracts, it is very hard here for people to find an NHS dentist for example. By dumbing down TV, (people seem obsessed with reality tv) and the news we are not doing anyone any favous, there are good science programs on. We have a serious knife crime problem here (alone) and no one seems willing or capable of debating the issue, the causes and what we should do to stop it. So it just carries on, innocent people dying and no one gets a grip. At least there are other channels e,g ITV and Channel 4 that also have news, but with a different perspective so to get a objective view watch more than 1 news source. On a slight tangent here, what came out of that story from a month or two ago, where a truck was found on the US side of the US / Mexico border with immigrants (mostly dead I think) in the back having been smuggled across the border. The driver escaped I think but may have been apprehended. It hit the news here, then went silent. It seems human life is, to many not worth very much, when money is involved, so that seems to link with people being in as you said "slave workforce".

I think you have a valid point here, people are worried their way of life will be some how impacted by immigration oddly immigration can bring a new perspective to a community, new food from shops opening up selling different goods to other shops. It is a case of being open minded and opening doors to your new community members and making them feel welcome. What has happened in the Uk for example is that say a community centre has closed (lack of use) and it gets turned in to a Mosque for example, so for this Muslims are likely to be blamed, not the fact that the community allowed the centre to become unused.

Agreed, we are sleepwalking in to oblivion, well the west is at least.

IIRC social media played a big part in this, apparently people in areas where there were immigrants were fed a narrative that there was also a high crime rate, so they would buy the election propaganda that we need a border wall etc. But off topic, over here in the UK lots of young people are using small canisters of Nitros Oxide (it is the new party drug apparently) but the narrative is spread on social media. so others follow suit, despite the fact it is dangerous So while social media plays a part in all this, we probably need a better education system that teaches critical thinking,

well if we get 4 more years of trump or someone like him, the west is probably finished,

I think due to the way the media (or some of it) reports things, the reality gets rather skewed. But when you put it the way you did, I agree with you on this, it was a bad move. just makes people more worried what will happen if he gets in again. Didn't trump try the same thing with Putin ? with what seems a similar result. Why I am here rather than on 'social media' better more constructive discussions. I don't mnd making errors in how I have interpreted something because the response here is rational and explained.

What I meant was, if we had 'none of the above' on a voting form, then it would probably win, i think people on both sides of the Atlantic are just fed up with the current choices of political party. I think replied to "I'm in for $10 on "none of the above". But posts got merged, so something was lost on the way, sorry. Paul

I seems that who ever is in power President / party , it ends up being down to who controls the upper house (senate if I understand things) as to if things get through. Unless the president signs executive orders (which trump did seem to sign quite a few) Solving the underlying problems, that are behind many of the larger problems is, as with the UK going to require a long term strategy Right now in the UK we have a cost of living crisis, a crime problem and many other issues, our MPs are on summer recess and we are also waiting to find out who windows the Conservative leadership race, all this while people are struggling to make ends meet. Until then we seem to be in Limbo as no one wants to make a decision until the new leader is in place. Both sides have ideas, no one which seem to be long term, we need common ground, Western politics seems to be broken on both sides of the Atlantic, but America is seen as a country that takes the lead, and needs to be strong for others to follow and for the west to stand up to aggression.. Granted Donald Trump was also right when he said other NATO countries need to pay their way fully too. I don't exactly agree with Donald Trump on many things, but I did like the fact he tried to reach out and talk to North Korea, regardless, surely dialogue is better than mistrust and actions that could risk all out war. In the absence of other ideas. Paul I am sure that if that was on the voting form it would win a landslide victory on BOTH sides of the Atlantic, which may kick modern politics in to changing their course.

So from a UK perspective, which one of those is better?

Lol, Oops

Yes, I read that too, should be fairly simple, but you may need a lot of molten sulphur for that to produce a nice amount of sulphur with the rubbery properties. Melting in a test tube, if you try and pour in to water it ends up solidifying before it reaches the end of the tube, last time I tried that was years ago, so was about 14/15 at the time and had to do chem outside at that point as I was banned from the kitchen

I am sure you may be able to buy Sodium Citrate,

I think swimming pool chemicals contain chlorine, my chemistry set also had I think Calcium Oxy Chloride, which I think decomposed in to maybe Calcium Oxide and Chlorine. Problem is that the gas is still dangerous, in a lab you would probably use a fume cupboard for handling it. I can't help much with this though.

Once we start running more sample return missions we may get a better picture. However IIRC the current mission to collect Mars samples is more to do with finding evidence of life than perhaps determine mineral composition. We may not know until those samples are returned successfully.

I decided to create this so people can discuss the upcoming Artemis 1 mission to the Moon. I will also be creating a blog post and other resources (for displays) so hopefully encourage people here to discuss further. https://www.nasa.gov/artemis-1

Thank you for this, it makes more sense now,. So I guess the same would apply to other molecules being in different places, that have the right properties for vibrations. I think water does as I read about that years ago. Interesting stuff. The JWST is going to hopefully gives us lots of science, so will be good to see what papers & articles etc are published over the coming years. Paul

Hi I am not sure if this question is quite in the right place, but it seems appropriate. Just been watching the August Space telescope science institute lecture, looking at images and spectra from the James Webb Telescope, https://www.stsci.edu/contents/events/pls/2022/webbs-first-look-images-and-spectra-from-nasas-newest-great-observatory I have a question regarding a slide on atmosphere spectra to determine the composition and have attached a screenshot of the slide According to this, Some of the molecules exist at different ranges in the electromagnetic spectrum for example Water seems to be at between 5000 and 10,000 nm but also between (or closer to) 20,000nm Is this due to how these molecules exist in the atmosphere so Liquid and gaseous states, I think they said they detected water haze on the planet described. Or is there another reason why molecules appear in more than one place.? I am not too sure on the right terminology but do understand that different molecules are absorbed and hence we can work out by absorption which molecules they are. Thanks Paul Sutton

As an update to this, I am repeating the original experiment with some lab grade Sodium Chloride. This will hopefully generate some nicer cuboid crystals. From there I want to try and look at obtaining a seed crystal and then growing from that. Also made sure the NaCl solution is saturated. Will see what happens. All fun stuff, hopefully over time I can repeat with other solutions such as Copper Sulfate Paul

sorry, I mis read the list of items needed 0.1 M ethanoic acid ( there is a space in there for a reason eh) my bad but lack of experience with this. Once i spotted this, I edited my original post but not the title. Hmm, i was just quoting their information sheet, i didn't think of it as flammable either. This is why we have materials safety data sheets I guess to get accurate information. If reaction with bicarbonate of soda would give of CO_2 anyway. The method uses 3 different brands, one of which has bicarbonate of soda. I have attached the method sheet for reference. istoothpastebasicstudentsheet_513804.pdf

Hi I have been looking at a resource, on the Royal Society of Chemistry website. This is a school investigation, to look at if toothpaste is basic, and therefore can neutralise an acid https://edu.rsc.org/ideas/everyday-neutralisation-myths-busted/4015026.article This investigation is aimed at UK Secondary aged students 11- 14 years. I was thinking, if this could be adapted for use in primary schools ? This experiment uses 0.1 M ethanoic acid (danger: corrosive and flammable) would using white vinegar (this is still ethanoic Acid ) be a good substitute for use in primary education. ? Which is probably far safer. I would guess vinegar is a much lower concentration or more diluted. I am not a expert at all this, but it should work. Thanks Paul Sutton
