proton

Definition

A positively charged subatomic particle that lives in atomic nuclei and determines what element you're dealing with, composed of two up quarks and one down quark for those keeping score at home. This fundamental particle is why hydrogen acts like hydrogen and not like, say, uranium. It's basically the atomic bouncer that decides which element club you're in based on head count.

Example Usage

The cyclotron accelerated protons to nearly light speed for the particle physics experiment.

premise

The foundational assumption you build an argument on, which may or may not be complete BS but sounds convincing enough to keep going. In logic, it's one of the propositions in a syllogism that leads to your conclusion; in real estate, it's the property itself (usually plural). Basically, it's your starting point—choose wisely, or watch your entire argument collapse like a house of cards.

lecture hall

fermi

An obsolete scientific unit equal to one femtometer (10⁻¹⁵ meters), named after physicist Enrico Fermi because apparently scientists enjoy naming impossibly tiny measurements after their colleagues. This is the scale where you're measuring things like atomic nuclei, where the concept of "really, really small" takes on a whole new meaning. It's been largely replaced by the femtometer, but physicists still use it occasionally when they want to confuse undergraduates.
