Safer Internet Day

sid

Today is Safer Internet Day also known as SID. This year marks 20 years since the campaign started.

There are lots of resources on the website, and schools should be running sessions so as your teachers for details.

There are lots of things we can do which still make using the internet enjoyable and educational, but a safer experience. Not sharing personal information, being mindful as to who we are communicating with, to perhaps changing our social media to platforms that are more privacy friendly, seeking accurate information, see Sense about science for details and have a look at their 'ask for evidence' information. This is also a good way to avoid misinformation by fact checking what we read or see online by developing the skills to do so.

This article may also be useful too When critical thinking isn’t enough: to beat information overload, we need to learn ‘critical ignoring’

Simple changes could also include switching from google to duckduckgo for search, installing privacy essentials will also block sites such as facebook from tracking you. I don't notice this as much as I have simply blocked facebook and meta.

I also block cookies as much as possible, these are not needed esp any integration with analytics.google.com serve no real purpose other than to spy on you.

Testing out a syringe to measure reactant produced.

The British Science week primary pack has an experiment using

  • Water
  • Sugar
  • Yeast
  • 3 samples of water at different temperatures

The idea is to determine which produces the best reaction

The experiment uses a balloon to collect the $CO_2$ produced, and uses a tape measure to compare the results.

I am trying to modify this a little to avoid using a baloon, but use a syringe instead.

So the set up I am looking to use has

  • Conical flask
  • Bung
  • Glass tube
  • Rubber tube
  • Syringe
  • Clamp Stand set up to hold the syringe

I have just tested this set up but used Bicarbonate of soda & Citric acid and then added water using a dropper to start the reaction. Putting the bung in quickly so the $CO_2$ doesn't have time to escape. Sure enough the syringe plunger moved as the gas was pushed in.

So the next step is to set this up at the library and use the ingredients above. I plan to set this up before the STEM group on Saturday and observe during the session, which should be over a good few hours. I can then tweak before the next session on March 11th.

New form of Water found

This was posted to the fediverse on 4/2/2022. Really interesting how strange and diverse a simple molecule such as Hydrogen Oxide is.

Magnetic fields on cosmological galaxy mergers

This is an interesting paper on Archive. Looking at how magnetic fields and galaxy mergers.

I have added links to the thread on the Fediverse, and provided a link to Science Forums for further discussion.

Mars : Exploration vs Exploitation

The BBC [1] have an article [2] today where Bill Gates, discussing that he would prefer to pay for vaccines than fund trips to Mars. My comment is not about this directly but the latter part of this article looking at going to Mars.

Fellow entrepreneur Elon Musk has said he wants to colonise Mars, while Jeff Bezos has also joined the "space race".

SpaceX, the rocket company co-founded by Mr Musk in 2002, has made it an ultimate goal to send crewed flights to Mars and eventually colonise the Red Planet. 

This raises a few questions, what do we mean by colonise?. If we look at history, white Europeans, have colonised North / South America, much of Africa and Australia as well as other countries. This was based on the assumption at the time that they were in some way superior. So history is being repeated here.

Do we, as humans have the right to decide that we are going to simply colonise Mars? If so, how? It is as if it is ours to colonise.

In terms of ethics, we need if we look at both Jeff Bezos and Elon Musk, we can conclude they are very successful. However look at Twitter, after Elon Musk bought it, he has made changes, sacked a huge number of workers, and seems to be banning journalists, banning people mentioning alternatives (e.g Mastodon) and allowing right wing extremists back on. Yes the buck stops with the CEO.

If we now take Jeff Bezos (Amazon CEO), we have had Amazon workers on strike, over conditions, timed toilet breaks [3]. We should examine if those at the top are ethical, in the way they got to where they have done. What are their actual intentions.

From a Science / exploration viewpoint going to Moon / Mars is part of human nature and desire to explore. We can go there to explore, learn and develop our curiosity and understanding further. As the paper [4] says, in terms of mining, we need to take in to account there are cultures on Earth that consider the moon Sacred, so if we deface the moons surface, we affect those cultures, we would not burn a copy of the Quran or Bible in public, if we did we would be arrested. Would changing the moons surface, sufficiently enough to be visible from Earth any different to damaging sacred sites. We already have open mines that are huge. National geographic have an article discussing the destruction of Palmera by ISIS [5]. This caused international anger.

There are papers discussing this issue, one is ethical exploration [4]. There is a difference between having a colony on the Moon, Mars or elsewhere and simply a presence on those celestial bodies. We need to avoid the mistakes or assumptions of the past that everywhere is for humans to just exploit or rather specifically mostly White Europeans and probably more recently White Americans, wiping out indigenous people, so I guess we should include Canadians and Australians, and South Africans in that. But those countries are borne out of European explorers and colonisers.

I have added a link below to science forums, but we can also discuss on the fediverse.

We need to find a way to explore the cosmos peacefully.

Code Club 4/2/2023 – repost

Paignton Library code club 4/2/2023 10 am to 12:00, Happy to stay till 13:00.

Paignton Library code club is attendee ship is picking up nicely, We are still using scratch but some of us are slowly moving to text based languages in some form or other.

The core code club activities are still available. If you have been Scratch or other block based coding for a while then you may want to start looking at the next stage. which could be useful if starting with the Raspberry Pi.

I have included a link to the GNU/Linux command line BASH shell tutorials,

If you would like to start undertaking more with Python, we have 4 copies of the Python for beginners book on the shelf, and there is a copy in the Library which can be borrowed. The Pis and laptops / netbooks do have Python installed. But it may just be easier to get a Repl.it account

Going further, the two laptops I gave out on the 7th have the GoDot game engine installed, this is for creating more advanced games, the main language for this is GD Script.

For those of you working on Responsive web design then this seems to be going really well.

There are also some contests you can get involved with, some of these are listed below.

Search for gravitational waves set to resume

Search for gravitational waves set to resume following COVID-19 setbacks

Physics world have reported that the The LIGO–Virgo–KAGRA will resume. They are looking for gravitational waves. You can read the full article here. Back in 2021, there was a talk at FOSDEM about Virgo which I made a post about on 7/3/2021.

There is some info on Ligo at the STEM group, which I can re-display if anyone is interested.

Trumps latest tirade – a dire warning

This was posted to the Fediverse earlier, It serves as a dire warning that the US Republican party is very dangerous. We are already seeing book banning in some states, unless those books are approved, schools that have had books donated are clearing shelves, under the threat of a 3rd degree felony charge. And Trans issues does seem to be one of the reasoning behind this.

They are also allowing puberty blockers / Testosterone treatments for cis children, but NOT those who are Trans. It does not take a great deal of intelligence to see what is going on here.

If you are not aware of this, have you been living in a cave for the past few weeks ?

I am sharing this here to help RAISE AWARENESS, these comments are not only disgusting, but show that there are serious issues in society.

This is the SAME Donald Trump that Nick Clegg, former UK deputy prime minister seems to feel is safe enough to be back on Facebook. Trump knows he won't be kicked off Facebook for comments made away Facebook hence the above was on his social media site (don't forget he got in to legal trouble for breaching the AGPL).

He is also facing at least SIX SERIOUS charges including inciting insurrection.

How he was allowed to be back on Facebook is beyond my comprehension. All I can think and a few people have mentioned this on Fedi, is that the decision is about money, after all that is what Facebook is good at, collect data use to sell adverts and don't give a damn about safeguarding anyone on the network.

The UK online safety bill won't even scratch the surface with this,

On the banning of books in schools, this is where it starts, suppress knowledge of groups of people or ideas etc.
