Negative Energy: Understanding Hydrogen's Electron
In a hydrogen atom, the electron is bound to the nucleus, so its energy is negative. This shows that it is in a bound state. When there is negative energy, it means that the electron is stable. It is inside the atom because its negative...

Why Did Einstein Hate Randomness?
How random are things, really? Well, at the tiny level of photons, randomness might be key to their existence. Einstein could not accept this and famously held the paraphrased opinion that, ‘God does not play dice with the universe’. In...
