From cosmetic chemistry to Victorian love poems, plus a secret mathematical surprise, the Ri has something for everyone to geek-out to on Valentine's Day.
If flowers aren't exactly your thing, why not try saying 'it' with… maths?
Just send your Valentine the following equation and tell them to copy and paste it into Google search:
5 + (-sqrt(1 – x^2 – (y-abs(x))^2)) * cos(30*((1 – x^2 – (y-abs(x))^2))), x is from -1 to 1, y is from -1 to 1.5, z is from 1 to 6
Or simple try it for yourself.
Is that the smell of love in the air? No, it's the smell of bath bombs! Nothing says ‘we’ve got chemistry’ like home made bath bombs for your beloved. Their heart will fizz more vigorously than the reaction between citric acid, sodium bicarbonate and water.
We have one final option for those of you who are classic romantics – poetry, inspired by a collection of John Tyndall’s Valentine’s poems in our archives.
Tyndall was a brilliant physicist, glaciologist and mountaineer who made major waves in atmospheric physics, and thrilled his Victorian audiences in the Ri lecture theatre with demonstrations of his experiments.
A brilliant poet he was not, but the sketches really bring it to life.
Our favourite verse is:
‘In pretty strife, to start to life, my waking atoms stir. Their motions fine, to thee incline, my heart’s thermometer!’
These poems weren’t actually serious love notes, but a running joke between John Tyndall and his friends. If after all of this you’re still a ‘despiser of St Valentine’, this last one is for you:
"Go mourn for Venus' broken laws,
In brazen-throated Siren's jaws:
This only serande be thine,
Despiser of St Valentine."
Happy Valentine's Day!
