Rovelli is what happens when a serious physicist is also a beautiful writer. His books are short, read like poems, and they're about the actual frontier of physics.
His thing is time — and he gently dismantles it. The idea that time flows the same everywhere, that there's a universal 'now,' that past and future are fixed? Physics says it's all more slippery than that.
Underneath, his view is strangely freeing: reality isn't a collection of solid things. It's a web of events and relationships, constantly happening. You're not a fixed object — you're a process, a happening.
For someone feeling lost, there's comfort there. You're not a broken thing that's supposed to stay the same. You're a flow. Of course you're changing. That's what you are.
