Albert Einstein struggled with his theory of everything because he lacked a guiding physical picture, which is essential for scientific breakthroughs.

Einstein viewed the universe as a vast library filled with mysteries, where he could only grasp the first page of knowledge.

Mathematicians care about whether something holds true 100% of the time, unlike most fields where 99.99% suffices. This is crucial in fluid dynamics, where we need to understand if there are special initial states that could lead to blow-up scenarios.

Quantum entanglement means that when two particles are entangled, measuring one instantly determines the state of the other, regardless of the distance between them.

In quantum mechanics, particles like electrons can explore every possible route from emission to detection, which many physicists now accept as a correct description of reality.

In the subatomic world, the rules are consistent with the observable world, and understanding how our perceived reality emerges from subatomic behavior is crucial.

Einstein believed in two types of God: the personal God of the Bible and the God of order, simplicity, harmony, and beauty, reflecting that the universe is not chaotic; it's beautiful and can be summarized on a single sheet of paper with all known laws of physics.

The methodology of science should not be solely based on empiricism, as it can lead to misconceptions about quantum theory.

In quantum mechanics, you can ascertain the state of a system, but you cannot confirm it in the same way you can with classical systems.
