Plotinus believe that there are three beings that command practical life - and that the third is beyond being. These three beings are a)the soul, b) the intellect and c) God. Love and desire form an inferior fourth dimension that mixes us with the world of genesis. #philosophy
I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Enlightenment is man's emergence from his self-imposed immaturity. Immaturity is the inability to use one's understanding without guidance from another.
In his 1924 PhD thesis, Louis de Broglie proposed that particles can exhibit wave-like properties, a concept known as wave-particle duality. This was a fundamental shift in how particles such as electrons were understood.
When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity.

Electrons have a property called spin, which is a bit like an intrinsic form of angular momentum. Despite the name, electrons don't actually spin around their axes like planets. Instead, spin is a quantum mechanical property that doesn't have a direct analogy in classical physics. Interestingly, the spin of an electron can only take one of two possible values, which are typically described as "up" or "down." This quantization of electron spin is fundamental to many aspects of quantum mechanics and is crucial for technologies like magnetic resonance imaging (MRI) and quantum computing.
The word algebra comes from the Arabic phrase al-jabr, which means "reunion of broken parts," and was used in the title of a 9th-century book by mathematician Al-Khwarizmi that played a crucial role in developing the concept.
