Quantum Computing & Tech ⚛️ on Instagram: "This is not CGI. It’s a single atom. Captured by physicist David Nadlinger, this image shows one strontium atom suspended between two electrodes, held in place by electromagnetic fields inside a vacuum chamber. When blasted with precision lasers, the atom absorbs and re-emits light so strongly that it becomes visible to the naked eye. A fundamental building block of reality, isolated and glowing.

Memes on Instagram: "Real Quantum Gravity and the Unification of Physics Modern physics rests on two pillars that are both extraordinarily successful—and fundamentally incompatible. Quantum mechanics governs the smallest scales of reality, describing particles as probabilities and interactions as quantized events. General relativity, on the other hand, explains gravity as the smooth curvature of spacetime itself, excelling at cosmic scales. Each theory is correct within its domain, yet when forc
