We celebrate the Year of the Trident the best way we know: on the open road.​ An epic journey that brings Maserati back to its origins, from Shanghai to Modena, crossing continents, landscapes and cultures. ​ The first stage starts in Shanghai, a city defined by speed, precision and forward momentum. A place where everything moves fast – the perfect expression of the Maserati spirit. From here, a fleet of Maserati leads westward, towards Jingdezhen, marking the first chapter of a route that will unfold mile after mile, all the way back to Modena. Let the journey begin.​ #Maserati #100YearsOfTheTrident #MaseratiGrecale #MaseratiGranTurismo #MaseratiGranCabrio

The Hessian matrix H(f) of a function f: Rⁿ → R is the n×n matrix of all second partial derivatives. For f(x,y): [ fxx fxy ] [ fyx fyy ] Definition: [ ∂²f/∂x₁² ∂²f/∂x₁∂x₂ ... ∂²f/∂x₁∂xₙ ] [ ∂²f/∂x₂∂x₁ ∂²f/∂x₂² ... ∂²f/∂x₂∂xₙ ] H(f) = [ : : : ] [ ∂²f/∂xₙ∂x₁ ∂²f/∂xₙ∂x₂ ... ∂²f/∂xₙ² ] In compact form: [H(f)]ᵢⱼ = ∂²f / ∂xᵢ∂xⱼ Named after German mathematician Otto Hesse (1811–1874). Used to study curvature, convexity, and classify critical points in multivariable calculus & optimization.

Lenz’s Law: It explains that the direction of an induced current is always such that it opposes the change in magnetic field that produced it. In other words, if a magnetic field through a coil is increasing, the induced current creates its own field to push against it. If the field is decreasing, the induced current creates a field to help it out. That’s why Lenz’s Law is basically the “nature hates change” rule for electromagnetism.

Fundamental Theorem of Calculus 2 has a lovely visual. Imagine you're climbing a mountain. Add up all the little changes in height as you walk up. You can approximate those little changes with the derivative. Then the sum of the little changes adds up to the net change.
