Blog Post #84: Day 21412

Dear Readers,

I am grateful for each moment of every day and, regarding the future, I know that it is always in God’s hands,

but tonight I do have some fun mathematical surprises that I hope to be sharing with more friends tomorrow…One’s life begins, of course, long before the date of birth, but for simplicity, if I count my date of birth (Wednesday 13 June 1962) as my day number 1, then tomorrow (Monday 25 January 2021) will be day number 21412 for me.

I find 21412 to be a rather beautiful palindrome containing the number 141 which has been special on many occasions throughout my life, and since 21 x 4=84 I am all the more happy to be writing about this now in Blog Post #84 !

Blog Post #83: Magical Duets!

Dear Readers,

My house number, 11, is a palindrome; so is 101 or 11 x 11 =121, but what about 11 x 101 x 11? The result 12221 is clearly palindromic, and it’s intended to let you know a very nice date for your diary: exactly three weeks from today, on 12.2.21, you’ll be able to enjoy on YouTube (at 19:30 Central European Time via and clicking on the banner there) a feast of fabulous, musical solo performances featuring many young talents of Musica Mundi School.

I have the pleasure of getting to teach Mathematics to every student who studies the subject at the school, and right now I have some delightful surprises starring Julija and Hoi Yuet.

Blog Post #82: Terrific Talents!

Dear Readers,

With special permission, of course, in today’s blog post I am delighted to be featuring a high five terrific young talents! Four of them are students at Musica Mundi School, and are therefore outstanding young musicians. All of them are also highly capable in Mathematics.

Blog Post #81: Top of the Class, Nice Niklas!!

Dear Readers,

It is with great pleasure that I thank everyone who participated in the ‘Good Lives Global Prize Competition’ (see Blog Post #80).

Andy H. from Scotland was the very first person to reply with all the mathematical puzzles completely correct. Andy loves challenge puzzles so much that he simply wanted to enjoy them without being given a prize. So, in recognition of his excellent attitude, we have a bonus puzzle in Andy’s honour, down below.

Before then, I want to congratulate Quintijn van Heek (an A-Level Maths student of mine) and Krissy Teng (another great student at the beautiful Musica Mundi School in Waterloo, Belgium) for also solving all the mathematical puzzles. Well done, Quintijn and Krissy!

Blog Post #77: Happy New Year 2021 Fun Brainteaser!

Dear Readers,

Happy New Year, 2021! Earlier today, I gave a brand-new brainteaser to my smart and lovely wife, Jenny. She said that it’s quite tricky, but she still succeeded in solving it within a few minutes! So, if you also like puzzles, then I warmly encourage you to enjoy tackling the fun brainteaser. In case the puzzle is not your ‘cup of tea’, I still most sincerely wish you a very happy New Year filled with love, joy and peace.

Blog Post #76: Magical Joy & Peace

Dear Readers,

Within my family of three, Michael (my son), Jenny (my wife) and Paul (that’s me!) try to be always thankful for everything. We like to think of M, J & P as representing Magical Joy & Peace.  The answer to the question “How long will it last?” depends on us properly recognising the everlasting source of true love, joy and peace.

Blog Post #75: Turn Over A New Leaf

Dear Readers,

I first heard the saying ‘Turn over a new leaf’ as a little boy, long ago. I have found the words to be very good, refreshing, encouraging and helpful for making positive changes. I can’t think of a better day to seriously consider turning over a new leaf than on All Saints’ Day, today.

Blog Post #74: For Genevieve, Julie, Marcello, Timothee and Yordi!!

Dear Readers,

This post is just in time to wish Genevieve a very happy birthday tomorrow, while it’s exactly nine weeks early for the birthday of Genevieve’s mum, Julie, a lovely lady I know through my Mathematics teaching. A bright student named Timothee is a keen chess player, as are ‘Mathematical Marcello’ (a boy whom I remember well from my previous school, especially when as a little 8-year-old then, he mentally calculated 99×99=9801 in just a couple of seconds!) and Yordi, who is a very good friend of my son.
