I made some new friends at the Great Barrier Reef - undoubtedly one of the most spectacular places I’ve visited. Scuba Diving has a risk value of 5 micromorts which means a 5 in a million chance of sudden death. Do you a think running a marathon has a higher or lower value?

Explaining my mathematical tattoos for Dr Karl... how many others do you recognise on my arm?

Shoutout to the ladies of PymbleLC for being such a fabulous audience. I hope you had as much fun hearing about ‘Mathematical Modelling in Sport’ and ‘Using Maths to Save the Ocean’ as I did talking about them!

Spent today writing about the maths of Harry Potter so this seemed the perfect photo. Who’s winning the duel?

Dr Tom Crawford asks Professor David J. Malan about his most obscure classes at college 🎓

Hands down the coolest place I’ve been kayaking. Loved my time on the water in Sydney, even though we spent most of it dodging boats! In 2015 there were 4850 boat moorings in the harbour, with the number growing at 3% per year. If this continues in what year will it reach 10,000?

It doesn’t get much better than spending 2 days on the radio with the LEGEND that is Dr Karl. Live Q&A’s from ABC Townsville, ABC Victoria, ABC Melbourne, ABC Canberra, and ABC Darwin to follow in the next few days. Maths and Science - the perfect duo!

A HUGE thank you to Iona for joining me for the #BigNumberNatter on National Numeracy Day 2024, and even bigger congratulations on a well-deserved award!

I still think you should get yourself a giant key though... (6/6)

FINANCE HACK: divide your age by two, and that is the % of your income you 'ideally' want to save towards your pension.

It's not going to be possible for everyone, but it gives you something to strive towards - and a great way to practice your maths on National Numeracy Day! (5/n)

Iona shares her 'top tips' for managing your money on National Numeracy Day regardless of your level of confidence with numbers.

I particularly love the idea of the 50:30:20 ratio for essentials, 'nice haves', and savings. If only I can stop my impulsive shopping habits...

Continuing the #BigNumberNatter on National Numeracy Day 2024, millennial money expert Iona Bain discusses her decision to speak out about her dyscalculia, and why she choose to tackle it head on.

And yes Iona, you are absolutely an inspiration :)

Blue Mountains National Park, a 2-hour train ride from Sydney. Australia contains 33,000 km of railway, which is more than twice that of the UK. If the average speed is 70 kph, how long would it take to travel the entire Australian network? And what is the optimal route to do so?

There are 8000 Quokkas on Rottnest Island but this one is clearly the friendliest! The young are born 27 days after mating and a female matures sexually after 18 months. If they live for an average of 10 years, what is the maximum number of joeys (offspring) a Quokka can produce?
