B Is this curve quadratic or exponential?

AI Thread Summary
The discussion centers on the nature of a curve derived from an orange bar graph, questioning whether it is quadratic or exponential. While infectious diseases typically follow an exponential curve, factors such as delayed data reporting and vaccination efforts may cause the observed data to appear quadratic. The impact of lockdowns is also mentioned, suggesting they should disrupt exponential growth patterns. Participants reference online calculators for SIR models and a paper that further explores the nuances between quadratic and exponential modeling in disease spread. Understanding these distinctions is crucial for accurate data interpretation in epidemiology.

I got this from orange bar graph with dy/dt =ky. But with so many unknowns in cases reporting maybe a quadratic curve would be more accurate ?

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
