<h2 class="section-title">What is Scientific<br />Machine Learning?</h2>
<p class="section-body">
Classical ML learns patterns from data alone. SciML goes further β it fuses the expressive power of deep learning with centuries of accumulated scientific knowledge encoded in differential equations, conservation laws, and physical symmetries. The result is models that generalise better, require less data, and produce physically consistent predictions.
</p>
<div class="def-card">
<div class="def-card-label">// core idea</div>
<div class="def-card-title">Physics-Informed Learning</div>
<p class="def-card-body">
A SciML model doesn't just minimise prediction error on training data. It simultaneously satisfies <strong>governing equations</strong> β such as the Navier-Stokes equations for fluid flow, SchrΓΆdinger's equation for quantum systems, or Maxwell's equations for electromagnetics β as soft or hard constraints during training. This means the model is <strong>physically consistent by construction</strong>, not just statistically plausible.
</p>
<p class="def-card-body" style="margin-top:1rem;">
The canonical example is the <strong>Physics-Informed Neural Network (PINN)</strong>, where the loss function is augmented with PDE residuals evaluated at collocation points scattered throughout the domain. But SciML extends far beyond PINNs β it encompasses equivariant architectures, neural operators, differentiable simulators, and generative models for scientific discovery.
