Round 1 of our machine learning potential really wants oxygen atoms in water to cluster together 😂

Had a great time at the Museu de les Ciències Príncipe Felipe in Valencia, Spain.

Saw lots of kids engaged with science and the Chromosome Forest exhibition covering much of biology. I can just about forgive the artistic licence in the DNA model.

When you're training a force field and step 2 of the simulation looks like this.

One surprise is how similar the gradients are between reversible simulation and ensemble reweighting, two different approaches.

We do see evidence that reversible simulation gives more stable gradients over repeats.

Differentiable molecular simulation is promising for training force fields but has 3 problems: high memory cost, slow run times and unstable gradients.

Here we solve these by explicitly deriving and computing the gradients from AD.
