Have you ever seen a snowflake up close? Have you smelt fertiliser on a country drive? Chemistry is the most sensuous of the sciences, and it may just be the most beautiful too. In our latest SCITalk, Dr Philip Ball showcases the breathtaking beauty of chemistry.

Even the most disciplined of us falls into these rogue states from time to time, minutes of total absorption unrelated to work or duty. For some, it is the humble cat video. For others, it is the endless tapestry of Twitter.

For me, this morning, it was a time-lapse video of crystal growth patterns. The world temporarily stopped moving as I fell headlong into high-resolution pictures of icy fronds appearing and clusters of spikes combining to form crystalline towers. Who knew potassium nitrate, ammonium chloride, and monopotassium phosphate could be so beautiful?
It turns out, Dr Philip Ball did. He knows all about the beauty of chemistry – from its profusions of colour to the hypnotic beauty of snowflakes forming.

Dr Ball argues that chemistry is the most sensuous of the sciences. Which of us hasn’t smelt the stink of sulphur or the sting of ammonia in our nostrils? When he unveils vivid, other-worldly pictures of chemical gardens, or even when we see a close-up of water being added to a bowl of M&Ms, it’s hard to disagree with his view.
This Wednesday evening, 25 May 2022, Dr Ball will deliver his SCI Talk about the beauty of chemistry and his book of the same name, which he put together with photographers Yan Liang and Wenting Zhu. Using microphotography, time-lapse photography, and infrared thermal imaging, they have captured astonishing photos of chemical processes.
They have captured a beauty seldom seen, except by chemistry’s day-to-day practitioners. They show us the chemistry of champagne in a new light and the transformations of evaporation and distillation. They unveil the strange world of chemical gardens – from the blue tendrils of copper nitrate in sodium silicate solution, to the silky precipitation of silver chromate.

Some defend the beauty of science by conflating it with the pursuit of truth. As the famous snippet from Keats’ Ode on a Grecian Urn goes: ‘Beauty is truth, truth beauty.’ Yet, it’s clear that the beauty of chemistry does not need to be defended in such abstract terms. It’s there in champagne bubbles and the deft configurations of a snowflake. You just need to look into a microscope - or plunge mind-first down a YouTube rabbit hole.
