According to **The Guinness Book of Records** the largest chocolate Easter Egg went on display at Le Acciaierie Shopping Centre, in Cortenuova, Italy, on 2011.

** Egg Weight = 7,200 kg = 15,873 lbs**

**Height = 10 m = 34 ft**

**Circumference = 19.6 m = 64 ft**

**The sugar content for easter eggs is: 55-65% by weight**

**So we will assume the sugar content of the giant egg was in the middle:**

Australia is reviewing its Maths Curriculum.

Sides are taken. Arguments are rife. See the excellent article by Donna Lu, **Cracking the formula: how should Australia be teaching maths under the national curriculum?**, The Guardian,13 FEB, 2022)

Should teachers teach? Or students explore problems? (Called Cognitive Activation in academe!)

Why not, both? Then add **outdoor maths** (below) plus **defronting the classroom** sometimes and **try some maths selfies** for homework. More ideas **here**.

It doesn’t matter what’s written in the curriculum, the biggest problem in maths for students is

Here, to tackle boredom are:

“**A growing body of research shows us that outdoor play leads to better physical and mental health, has positive effects on cognitive function and learning, and reduces the incidence of behavioural problems**.” Maria Zotti, **Nature Play, SA**.

Peter Dunstan, Principal Kilkenny PS, SA, writes in **SAPPA** magazine, Primary Focus, that outdoor play fosters “**wonderment, independence and freedom**” as well as “**social skills, imagination, creativity and problem solving**”.

Inspired by SAPPA and NaturePlay, Mathspig has produced her own outdoorsy maths list:

What is all this monkey business? It started in 1973 when Princeton University professor Burton Malkiel claimed in his bestselling book, **A Random Walk Down Wall Street,** that “A blindfolded monkey throwing darts at a newspaper’s financial pages could select a portfolio that would do just as well as one carefully selected by experts.”

In other words, the stock price movement is random.

Now in its 12th edition, the book tackles Investment Bubbles including Bitcoin. Is there a Bitcoin Bubble? According to the ABC on 24 MAY 2021 this was the Bitcoin Bubble Graph:

So can you beat the financial market? Try this **2D Random Walk** game (pic below) to see if you can guess the next random move and beat the system.

In the game, you have to remove gold blocks by clicking on blocks in the way of the moving green dot, but you lose energy (lose money, perhaps) each time you remove a block. Can you guess where the green dot is moving? Can you survive? Mmmmm! Good Luck. You’ll need it.

Mathspig can remember the horror of the ZODIAC MURDERS in California in 1968-69.

1969 was a very big year for psychopaths as the creepy Sharon Tate Murders by **Charles Manson and his ‘Family**’ also happened that year.

The ZODIAC murderer, who killed, at least, 5 people and sent encrypted messages to the San Francisco Chronicle, has never been caught. After 51 years the 340 cipher with 340 characters (below) was cracked last week.

The 340 cipher was cracked by of Jarl Van Eycke, David Oranchak, and Sam Blake, computer programmers and codebreakers from Belgium, the US, and Australia. Sam Blake is a Melbourne Mathematician.

You will find everything you need to know about these codebreakers at The Nerdist Blog **here.**

The ZODIAC murderer used all 3 Cipher Methods (**See blog Above**) to write the cipher.

The Zodiac combined a **PIGPEN** style cipher with a **PLAYFAIR** type cipher. The code breakers knew the key (below) from other ZODIAC messages.

The problem was the **TRANSPOSITION** Rule. The codebreakers’ programs had to sort through 650,000 **possible reading directions **to find the correct one for the cipher.

The diagonal of … include two-letters across, move down one row, then include the next two letters across, repeat, seemed to produce words.

The breakthrough came when Sam Blake divided the cipher into three blocks.

Finally, the message could be read. The ZODIAC murderer was a complete PSYCHOPATH, who thought he was collecting slaves for the afterlife!!!!!!!

If you are intrigued by this story then you will find these two videos by David Oranchak very interesting.

Eddie Woo is an Aussie Maths teacher who runs his own Youtube Channel. So popular is this channel in October 2015, **Woo** won the NSW Premier’s **Prize** for Innovation in Science and Mathematics. This youtube clip won’t tell you where you will use surds, but it does something magical.

It compares surds to different kinds of music to help students understand why mathematicians go crazy over the concept of surds. This clip tells why maths is soooooo special. There is no guesswork or fake information in this maths. Maths must be accurate. And surds demonstrate this point. (Look for the 5 min mark)

Maybe. Probably, not. But surds are used in mathematical programs that demand accuracy. eg. engineering skyscrapers, building satellite dishes, and even in video games. But you won’t see them. Like so much mathematics surds will be hidden in some algorithm.

Here are two Examples:

Often written a 1:1.61 the Golden Ratio or Fibonacci Sequence appears in art and nature and has an aesthetic appeal to the eye, but the accurate ratio is:

Satellite dishes, headlights, torches, and bridges all designed using the parabolic arc. The parabola is defined by the quadratic function and sometimes solving for x produces an irrational no. namely a surd. Rounding off can introduce inaccuracies that can become more dramatic when scaled up to the sie of, say, a bridge.
