The Schrödinger wave equation is a quantum mechanical equation that is used to measure aspects of a particle in a quantum system. It was pioneered by theoretical physicist Erwin Schrödinger.
The Schrödinger (wave) equation in this most simple form can be written H^ Ψ = ΕΨ.
H^ is called the Hamiltonian operator, and is written as H with a hat ^ but I can’t type that lmao.

The act of a member of the Royal Family waving at a member of the public but not in a Royal style (hand rotating in a forward direction with fingers fixed at a horizontal angle) but with their hand and fingers pointing to the person and them moving their fingers up and down in a friendly manner just like they are waving at an acquaintance.
In 1982 the Queen Mum waved at me with a Royal Finger Wave and not the usual Royal Wave whilst I crossed a bridge over the River Thames in London with my father.

When a man does not shower for a fortnight during summer and then unsuspectingly teabags their partner while they sleep.
I heard my ex girlfriend cheated on my while away on vacation so I did not shower while she was gone and gave her the Heat Wave Bag the night she got back.

Second-wave feminism was a period of feminist activity that began in the early 1960s and lasted roughly two decades. It took place throughout the Western world, and aimed to increase equality for women by building on previous feminist gains.
Man, I sure do love 2nd Wave Feminism , speaking of equality, lets improve some of our pre-feminist movements.

A human female, even if her name is not Karen, that's a total attention self generator, definition b) and who puts her anger, bitterness and lack of self worth on full display every time she's in public.

The act of using your right arm and extending your middle finger as in "the finger" or the middle finger (as in giving someone the (middle) finger or the bird or flipping someone off) as an obscene hand gesture but staying at a horizontal angle (much like a Sieg Heil but winding in and out your middle finger keeping your other fingers closed) whilst Ghost Riding past people and Police on your illegal Electric Bike thus giving the Police "the finger" Ghost style not like the Queen Mother who did this with all four fingers (Royal Finger Wave).
