The excellent** Maths Careers **site is managed and maintained by the Institute of Mathematics and its Applications. If your students wonder where Mathematics is used they will find plenty of answers here. See for example **Who employs mathematicians? **

For Valentine’s day we have an appropriate **article from Maths Careers, **did you know that 6 is a kissing number?!

Also, see **this post** with instructions on how to make this wonderful pair of linked Möbius hearts.

If you wish to get creative and try this I advise watching the Numberphile video carefully; following the instructions worked as you can see from my creation here! I can verify that unless you follow the instruction to make sure the twist in each strip is in a different direction you will end up with a mess! Quite an interesting mess but certainly not two hearts!….

Note the Desmos graphs on my strips. I created a file in Word **valentine-mobius-hearts** (or pdf: **valentine-mobius-hearts**) with Desmos images in a table. Adding dotted borders to the table gives guidelines for cutting. I began each cut by using the end of a paperclip to pierce the paper. See **Valentine’s Day** for the Desmos details.

To create my strips I printed the document and then printed again on the reverse. I then cut out and trimmed the strips so there was no white space at the end – the picture here has been made using strips 10 cells long.

Save your money on cards and send your loved ones (or anybody!) a math-o-gram!

Desmos have provided you with the means to **send a math-o-gram **to the mathematicians in your life!

Valentine’s Day seems an appropriate time to express love for Desmos!

Geeky people, you could even use the **Desmos API …**

For an alternative source of Valentine’s cards, we can turn to NASA! Take your pick from **this post** or these **fabulous NASA images**. (And don’t forget that **NASA provides us with many Mathematics resources**.)

Remaining with the loving theme you can also **express your feelings for WolframAlpha!**

For those in school this week try some Valentine class activities.

Here’s **a Valentine logic starter from Transum.**

This **Valentine Relay from Chris Smith **is excellent as are all the other relays in this excellent set of resources. You can find more excellent resources from **Chris on TES** and follow him on Twitter **here**.

I loved watching this Numberphile video on Mobius Hearts. Thanks for sharing the link!

Agreed Sarah, there are many excellent Numberphile videos.

This is truly awesome!!
