Evil Mad Scientist Valentines: 2018

2018 valentines

Today we are releasing our newest set of “Download and Print” cards for Valentine’s day. This is our sixth year, and sixth set of cards: The 2013 set had six equation-heavy cards, the 2014 set was a set of six symbol-heavy cards, and the 2015 set included love, hearts, and arrows. The 2016 set featured Pluto’s cold heart, and the perfect card for your robotic expression of love, and last year’s set featured atomic orbitals, exponential growth, and an epsilon delta declaration of love.

This year’s set features parallel lines, friction, and activation energy:

My love for you is at a stable equilibrium and therefore resistant to external perturbations

What could be more romantic than telling someone that the second derivative of your potential energy is at its minimum when you’re around them?

I'll Never be NP Complete Without You

The perfect card to give to any computer scientist when you want them to both (A) appreciate being given a valentine and (B) secretly wonder whether you don’t quite understand what np completeness means, or whether you do but thought it was funny.

Parallel lines never meet. But we should.

Parallel lines never meet. But we should.

It takes a special person to overcome my activation energy to send this card to you and ask if you will be my  valentine.

For when you have chemistry with someone.

Let's  measure our coefficient of kinetic friction

Why measure? Because it’s generally considered impolite to ask someone what their normal force is.

You can download the full set here, which includes all 36 designs from all six years (a 1.6 MB PDF document).

As usual, print them out on (or otherwise affix to) card stock, personalize, and [some steps omitted] enjoy the resulting lifelong romance.

Gravitrack marble machines by Solarbotics

GraviTrack

Gravitrack is a fantastic new build-it-yourself desktop-scale marble machine kit from our friends at SolarBotics, and available now at our store.

Gravitrack is available in two versions: A no-soldering battery-powered version (shown above), or a soldering-required solar version. We also still carry the original SolarBotics Marble Machines, in battery and solar flavors.
