A word used by the tech-savvy to sound smarter than the really are.
More specifically:
A math term that means perpendicular, but not just in 2D but in any dimension. Now commonly used to indicate an idea or concept that stands apart so much from everything else that it "sticks out," is "from left field," or is "third-way."
"I have this co-worker who keeps using the word 'orthogonal,' usually after he mentions some idea he thinks is God's gift to man. Can't wait to get this word into my vocab. Soon as I figure out what it means."
When incorporating Singapore’s bar model method—the problem-solving visualization strategy to tackle word problems—at the elementary school level and its aim to develop students’ pre-algebraic thinking skills (before they are introduced to formal algebra) are not often partially achievable or necessarily correlated in practice.
Wallet-friendly Singapore math textbooks, workbooks, and teachers’ resources on their own doesn’t guarantee problem-solving mastery—bar-modeling orthogonality seems to be a constant in many traditional American classrooms, often because of teachers’ or parents’ faux perception that a foreign math curriculum or publication is harder (or even inferior) than their local inch-deep-mile-wide one.
