Happy Sunday all / Dydd Sul hapus pawb!

Here in Wales year 11 pupils are in the middle of their GCSE exams. For maths, it's the last round of the current curriculum, and the first few exams of the new curriculum (WJEC exam board).

Once these exams are over in June I'll have availability for new tutees. I have some enquiries already so feel free to message or email if you are interested (no obligation).

Thanks / diolch 🙂

Prynhawn da pawb / Good afternoon all,

Today was the start of the new academic year here in the UK. I hope that it was a positive experience for all learners, and school staff too!

What is the link between maths and conspiracy theories? This video by Jeff Galak of Data Demystified demonstrates.

As the video explains, probability shows that a conspiracy theory that is actually true is highly likely to be found out. This is because it is highly likely that those involved in the conspiracy speak out. An example of when this has occurred was the case of the Tuskegee Experiments, which were found to be true when someone involved in them spoke out.

The probability of a true conspiracy theory being found out increases as the number of people involved increases, and as time goes on. This makes it highly improbable that a true conspiracy theory is kept hidden by those involved. Therefore, a conspiracy theory in which no one involved has spoken out is highly unlikely to be true, with the likelihood decreasing still further as time goes on.

This video refers to the academic paper “On the Viability of Conspiratorial Beliefs”. I have included the link to this paper in the comments section. The paper's abstract states that “historical examples of exposed conspiracies do exist and it may be difficult for people to differentiate between reasonable and dubious assertions. In this work, we establish a simple mathematical model for conspiracies involving multiple actors with time, which yields failure probability for any given conspiracy.”

If you have time to watch the video and/or read the paper I would highly recommend doing so.

Enjoy!
Sarah 🙂

Prynhawn da pawb / good afternoon all,

Last week I had the privilege of watching the year 6 Leaving Service at the primary school where I used to work.

I started with this class when they were in reception and I was with them for over 4 years. It was lovely to see how much they've developed and how creative they'd been in putting their own service together.

There was some sadness too, as one of the pupils from this class was lost to illness when just 9 years old (RIP). The class respectfully included her in their memories of their time at the school.

I wish these pupils all the best of luck in high school and with all of their future endeavours.

Prynhawn da pawb / good afternoon all,

This is a great article, explaining how Pythagoras Theorem is used to create right angles. This goes as far back as the building of the pyramids in ancient Egypt.

From "A World of Women in STEM".

Have you ever wondered what the very first math equations looked like? Or how ancient civilizations did things like measure distances, count numbers, and compute algebra without modern tools like rulers and calculators? When you see pictures of the Egyptian pyramids--or maybe you’ve even seen them...

Bore da pawb / good morning all!

Yesterday I returned from my study tour in Egypt. I saw the pyramids, fulfilling a lifelong ambition of mine.

The geometry used by the Nubian people in building the pyramids and other structures was very advanced. I'm going to look into it more and post about it soon. In the meantime, here's a few photos to pique your interest 🙂

Hello all,

My Master's Degree certificate has finally come through!

For anyone interested in my private tuition, I'm only doing online tuition (e.g. using Skype) and it costs £25 per hour. I'm hoping to have some space in about a fortnight's time.

Thanks,
Sarah
