What is a convex in science terms?

What type of word is convex?
Convex is a verb and can also act as an adjective. The adjective is the word that accompanies the noun to determine or qualify it.
Is convexity good or bad?
The higher the convexity, the more dramatic the change in price given a move in interest rates. Whatever you call it, after a while, if you keep braking a car it stops. After a while, if your bond is experiencing negative convexity, it also slows down/loses value.
What part of speech is the word petrify?
verb
verb (used with object), pet·ri·fied, pet·ri·fy·ing. to convert into stone or a stony substance. to benumb or paralyze with astonishment, horror, or other strong emotion: I was petrified with fear.
What is a convex vs concave?
Concave means “hollowed out or rounded inward” and is easily remembered because these surfaces “cave” in. The opposite is convex meaning “curved or rounded outward.” Both words have been around for centuries but are often mixed up. Advice in mirror may be closer than it appears.
What is difference convex and concave?
Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).
What means convex to the origin?
It is “convex to the origin” in the sense that if we “stand” at the origin, the point (0,0), and “look towards” the graph, we will perceive it as convex. In contrast, if we stand “above” such a graph looking towards it, taking “our” position as being the origin, it will be concave.
What do you mean by convex and monotonic preferences?
So, in two dimensions, with strictly monotonic preferences, strict convexity says that if two consumption bundles are each on the same indifference curve as x, then any point on a line connecting these two points (except for the points themselves) will be on a higher indifference curve than x.

Are glasses convex or concave?
convex-concave
Most glasses are indeed convex-concave. However the curvature of the convex side and of the concave side differ depending on whether you need a farsighted- or a nearsighted correction. So farsighted glasses would still be convex in total even though the back side may appear concave.
What is the reason for convexity?
Convexity is a measure of the curvature in the relationship between bond prices and bond yields. Convexity demonstrates how the duration of a bond changes as the interest rate changes. If a bond’s duration increases as yields increase, the bond is said to have negative convexity.
Why are mortgages negatively convex?
For bonds with negative convexity like MBS, when interest rates increase, a mortgage goes down in price by a greater amount than for normal bonds because the expected maturity of the mortgage becomes longer.
