Geometrical speculations have just as much Elegancy as Simplicity, and deserve just so much praise as they can promise use. -- Sir Isaac Newton

Vector fields help us see invisible forces like gravity, magnetism, and wind currents. They use arrows to show direction and strength at every point in space, like a weather map showing wind flow. From planets orbiting to air moving over wings, vector fields help us understand how forces shape our world! 📷 math.animations

Maxwell's equations are of great generality. They apply to all charge and current densities, whether static or time-dependent. Together, they describe the dynamical behaviour of the electromagnetic field. 1)∇.D = ρ 2)∇.B = 0 3)∇xE = -∂B/∂t 4)∇xH = J +∂D/∂t

Dmitri Mendeleev, born #OTD in 1843, was a Russian scientist who is best known for creating the periodic table of elements, which organizes the chemical elements based on their atomic weights and properties. He also predicted the existence and characteristics of some elements that were not yet discovered in his time. Besides his work on the periodic table, Mendeleev made significant contributions to other fields of chemistry, such as the study of solutions, gases, and organic compounds. He also applied his scientific knowledge to improve various aspects of agriculture, industry, and metrology in Russia.

In the 1960s, physicist John Bell proposed a theorem that could distinguish between the predictions of quantum mechanics and classical physics. Bell's theorem has since been experimentally verified.
