**They think maths is so important they even put maths on stairs. Here is some times tables art from Germany.**

**Mathpig just learnt this from a young Mathematician age 9.**

**It is a great way to do maths because you are thinking ‘Mmmm! How can I work these numbers.’ **

**Getting maths students to think about what they are doing is so much better than just having them guess ‘ Arrrr! Whatever. Click B.’**

**More jump strategy information here.**

**This will be very useful later when it comes to a similar method used to simplify long division:**

**Why not do something like this for your school.**

If an IMAGINARY NUMBER screams alone in a forest can you imagine that you can hear it? Ha!

But as Mathspig I am gobsmacked to find street artists devoted to mathematics too. Woo Hoo! More street art in my Kerry Cue Author Twitter feed. Click on sidebar.

In every volcano disaster movie from **Volcano** (1997) with Tommy Lee Jones to **Dante’s Peak** (1997) with Pierce Brosnan someone somewhere tries to out run a lava flow.

Is this possible? (See movie cliché busted by maths here.)

Now a lava flow from Hawaii’s Kilauea volcano is threatening tiny town of Pahoa, Hawaii again. (below).

You will find excellent information about the Kilauea and other volcanoes at the

US Geological Survey here.

As the temperature of lava exceeds 1000^{0} C there are very few ways to stop lava. According to the Taylor Kate Brown SMH (10 SEPT 2014) options include:

Bombing

Blasting (it with cold water)

Barricading it

Or adding concrete.

Lava from Kilauea travels 17 yards per hour so the lava velocity is:

V_{L} = 17 yds/hour = 15.5 metres /hour

(See Vox.com)

]]>Once lava flows are established new RIVERLETS can run on top of the original lava flow at great speed.

The fastest Lava flows recorded were in Hawaii in 1950 when Mauna Loa erupted. The lava traveled at 6 miles (10 kilometers) per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 60 miles/hour (97 kph)

**You are 2 km from the volcano rim and start running.**

**V _{L} = 97 kph = 1.6 km per minute (k/min)**

** = 60 mph**

**V _{H} = 18 kph = 0.3 km/min**

** = 11.2 mph (miles per hr )**
