Making chemical solutions
An important part of Chemistry is the ability to make up solutions of a known concentration. This can sound quite complex, however it doesn't need to be.
The following is some simple instructions that will produce 250m of 1molar concentration of Sodium Chloride
I have made this solution up using pure Sodium Chloride, from a chemical supplier [1], rather than table salt which contains Sodium Ferrocyanide. If you need extra help with this try asking on Science forums [2] as there is a section on there for home chemistry.
I am also on the IRCNow network, where we are starting up a channel to discuss amateur / home science.

Code Club 3/9/2022
The next Paignton Library code club is on 3rd September. There will be the usual mix of coding, troubleshooting and discussions. I should have some e-safety resources too.

Artemis 1 – Mission part 3
The planned Artemis launch for Monday 29th August was scrubbed due to a series of technical issues.
If all goes well, NASAs Artemis SLS will launch Saturday 3rd September and start a new era in the human quest to explore the Moon, Mars and eventually beyond.
NASA is heading back to the Moon, Artemis 1 is the unmanned test mission which if all goes well will lead in to further missions over the next few years.
Please take timings etc from the NASA website and NOT from this blog. I am not responsible for you missing anything.

Artemis 1 – Mission part 2
If all goes well, NASAs Artemis SLS will launch tomorrow (Monday) and start a new era in the human quest to explore the Moon, Mars and eventually beyond.
NASA is heading back to the Moon, Artemis 1 is the unmanned test mission which if all goes well will lead in to further missions over the next few years.
According to the schedule coverage starts at 12:00 am (morning) on Monday eastern time which would make it about 5am UK time (assuming EST is UK time – 5).
As full coverage starts at 6:30 a.m Eastern time, this would make it 11 am UK time so late morning (ish). The best way to ensure you catch the launch is to check out the social media / website and youtube channels which are linked to from the above schedule page.
Please take timings etc from the NASA website and NOT from this blog. I am not responsible for you missing anything.

Seeing universe's most massive known star
Astronomy is making fantastic new discoveries all the time, not just with space based telescopes but with ground based observatories too.
By harnessing the capabilities of the Gemini South telescope in Chile, astronomers have obtained the sharpest image ever of the star R136a1, the most massive known star in the universe. Their research challenges our understanding of the most massive stars and suggests that they may not be as massive as previously thought.
This article explains more.
We are improving our knowledge and understanding all the time, with new telescopes both earth and space based due to come online over the next decade alone. This is probably a good time to start looking at studying astronomy and being part of something really exciting.

Simple method destroys dangerous 'forever chemicals,' making water safe
Forever chemicals, known as PFAs, are found all over the world. Due to their nature, they are not broken down in nature.
As this means they are also found in drinking water, it puts humans at risk of harm. New research has found a way to remove these from water and make drinking water safer for consumption.

Wind turbine blades could someday be recycled into sweet treats
Interesting article on New wind turbine technology that is more sustainable and allows old turbines to be disposed of and recycled. This is an important step forward as waste is still a big problem so finding more environmentally friendly with producing green energy makes that greener and better for the environment.
Also included a link to Science Forums to discuss further, again please link directly to the original article.

Accelerator operators: pillars of particle physics
Interesting article from Symmetry magazine on the role of a particle accelerator operator. [1] This sounds like an interesting job and as the article says 'non traditional' so you never know where studying physics will lead to.
I have added a link to Science forums [2] if anyone would like to discuss further, however please add a link Directly to the article not this blog. There is no thread on there as yet.

Jupyter experimentation
Further to recent videos on Jupyter notebook, I have been doing some simple experimenting to get the feel of this.]
This reat for writing and data visualisation. As the following two example screenshots show. I have not fully written the code here, but I have made modifications. The table now shows total rows and columns after I did some research and figured out how to count columns.

Code Club 20/8/2022 Write up
So we had another quiet session today, with 4 young people, plus a parent, nevertheless it was productive. Time was initially split between looking for an iphone cable (could not find one), and also troubleshooting a Raspberry Pi, which seemed more successful.
There was also a discussion on e-safety, in terms of posting online and how this can have consequences later on, employers can do searches on applicants for example and also what to post, also a brief discussion on asking for evidence and finding proper, credible information on the internet, I did give peer review a brief mentiobn
It seems really beneficial to have conversations.
This has prompted me to dig out a few resources I have here at home. These are set to one side for the next session. I have also asked the library if they can send off for some copies of the Vodafone digital parenting resource.
We also have access to a tablet with the Lego WeDo software installed so if anyone is interested they can have a go at code club without having to bring along own devices. However attendees can, it really helps as you can store projects on your own device.
