AI Thread Summary
The equation for the temperature of the coffee is given as T(t) = P(441/450)^t, with an initial temperature P of 102 degrees Celsius. The user calculated that the coffee will reach 60 degrees Celsius after 26.4 minutes. However, WolframAlpha provides a more precise answer of approximately 26.265 minutes. The discrepancy highlights the importance of accuracy in calculations involving exponential decay. Clarification on the method used for the calculation could help confirm the correct timing.

13) The temperature of a cup of coffee can be approximated by the equation $$T(t) = P(\frac{441}{450})^t$$, where T is the temperature in Celsius, t is time in minutes and P is the initial temperature of the coffee. If the initial temperature of the coffee is 102 degrees celsius, when will the coffee be 60 degrees celsius?

So, my answer was that the coffee will be 60 degrees celsius after 26.4 minutes. Is this correct? I can show my work if it's wrong. Thanks.

WolframAlpha says the answer is $t=26.265$, which is pretty close to your answer.
 

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 '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...
