This is stronger than "everyday life" claim, and likely false. Note that the article carefully excludes "fancy telescopes": there is a reason.
For example, we can observe supernovae. We don't have satisfactory model of core-collapse supernovae yet. In other words, if you set initial condition to right before explosion and simulate forward, stars don't explode in simulation. And critically, it is seriously entertained that this may be due to physics beyond the Standard Model, unlike life or superconductivity: e.g. http://arxiv.org/abs/0710.3112 http://arxiv.org/abs/0710.3112

- sanxiyn 11y agoNo one seriously expects model of toddler collapse to lead to novel physics. Some (admittedly minority) serious physicists expect model of supernova to lead to novel physics.
- visarga 11y agoBut we can't predict when a toddler will collapse, or when she will start throwing toys, using the current understanding in physics, even if "The Laws Underlying the Physics of Everyday Life Are Completely Understood". What I am getting at is that we only understand the Low Level laws. We still can't understand, for example, financial markets or the weather. Complex dynamic systems are still beyond our horizon of understanding, even if we know how elementary particles behave. Another example, and this one is very basic: Predict the state of a system of 3+ bodies moving in space. https://en.wikipedia.org/wiki/Three-body_problem https://en.wikipedia.org/wiki/Three-body_problem
