AI Thread Summary
The discussion revolves around determining the number of birds in the original flock using a mathematical equation. The initial equation proposed is (b + 1)/2 + (b + 1) = 100, which is challenged by clarifying that "us" refers only to the original flock, not including the new bird. The correct interpretation leads to the equation b/2 + 1 = 100. This highlights the importance of accurately defining terms in mathematical problems. The conversation emphasizes the skill of forming equations based on contextual information.

Let b = birds

Met a bird = (b + 1)

Half of us plus you = (b + 1)/2 + (b + 1)

The equation is:

(b + 1)/2 + (b + 1) = 100

Yes?

No! the flock of birds is talking to the one new bird. When it says "us" it means the original flock, not with the new bird. "Half of us" is b/2. "Half of us plus you" is b/2+ 1.

Your equation is b/2+ 1= 100.

Another great math skill is the ability to create an equation from the given information in applications.
 

Thread 'Non-orthogonal bases'

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...

Thread 'Fermat's Last Theorem'

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...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

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...
