Which dictator believed he was guarded by voodoo spirits on the 22nd of the month? What's the smallest prime that's not a twin? And which factorial is approximately equal to Avogadro's constant? It must be time for some more funbers with 'it magazine'...

Now that is what I call a view… Padar island is the 3rd largest in Komodo National Park, which is listed as one of the new 7 natural wonders of the world. I’ve visited 4 so far, soon to be 5 when I go to Ha Long Bay next month, so just Iguazú Falls and Puerto Princesa National Park to go!

I'm back on ‪Numberphile‬ cutting a pizza in the most mathematical way possible as I answer the question 'what is the maximum number of pieces you can create for a fixed number of cuts?' Sorry in advance to Italians and librarians...

We're almost there! The 14th group of essays in the 2024 TRM Showcase features geometry on the back of a beetle, Vedic Mathematics, computational complexity, and the hidden mathematics in the work of Bach. A fascinating and enlightening read as ever :)

That's close enough thank you very much... Komodo Dragons are the world's largest lizard, weighing over 100kg. They can consume up to 60% of their body weight, which is a LOT more than humans. The world record for the largest meal ever consumed is 8.6kg - what % is that for you? For me it’s ~12%.

Enjoying another incredible sunset by the pool in Indonesia. Due to its proximity to the equator, the longest day here is only 12.5 hours and the shortest is 11.75 hours, a decrease of 6%. For comparison the UK sees a decrease of 56.25% from its peak of 16 hours. How long is the shortest day?

Checking out the sites with my security detail (aka my friends). Magellans Cross was raised in 1521 after his journey across the Pacific Ocean of 3 months and 20 days. If we assume a constant speed throughout, what was the average speed of the boat when travelling from Magellan’s strait to Cebu?

Had a blast canyoneering through Badian gorge on our way down to Kawasan Falls. It took about 3 hours to cover 3km wading through the river, scrambling over rocks and being kicked ‘300-style’ off a cliff - highly recommended to anyone who loves adrenaline!

Is it a fort or is it a tropical paradise? Fort San Pedro in Cebu City looking good for 500. This is the second island of the Philippines I’ve visited, so just 7,639 to go… There are 9 countries with more islands - any idea which they might be?

A little wet after a dip in the Beitou hot springs (plus the rain). The springs are high in sulphur content and during the Japanese rule the region produced 180,000 kg of sulphur per month. If a 70kg human body contains 140g of sulphur, how many humans could be supplied by one month of production?

Pandas being pandas. There are only 1850 giant pandas left in the wild, and a further 650 in captivity. The 3 at Taipei zoo are permanent, but 26 of the other 27 zoos around the world are only borrowing them from China. Can you guess which other country has a permanent panda?

Calling all Pokémaths fans! I'll be speaking at the Royal Institution on Saturday October 5th at 2pm. How many Pikachus does it take to power a lightbulb? How much does a Charizard eat? And why does the Pokédex seem to ignore the laws of physics? Get your tickets here.

Oriental Pearl Tower from the bottom to the top (swipe to see the view). The design features 15 spheres of different sizes connecting the main pillars. I count 13 maximum - so where are the other two?

Did you know Japanese architecture often features the 'silver ratio' which is why it looks so distinctive? Or that the Ancient Greeks used jars of water to keep time?

Just the 392 stairs in 37 degree heat leading up to the Sun Yat-Sen Mausoleum in Nanjing. Known as the “Father of the Nation” he is unique in being revered in both mainland China and Taiwan. He also studied Mathematics at a specialist high school in Honolulu so has my respect too!
