AI Thread Summary
To find the unknown value of N when $\log(N) = 9.52412 - 10$, it can be calculated using logarithmic properties. The equation simplifies to $N = 10^{-1} \times 10^{0.52412}$, leading to an approximate value of $N \approx 3.3428739 \times 10^{-1}$. The discussion includes a reference to a table, though the specific type of table needed is not clarified. The user seeks to determine the missing digits in the representation of N as $N = 3.34--- \times 10^{-1}$. The conversation emphasizes the importance of understanding logarithmic calculations and the use of tables in deriving values.

Not sure what you mean by "using a table". That would depend on what sort of tables you have available.

If $\log(N) = -1 + 0.52412$ then $N = 10^{-1}\times 10^{0.52412}$. My calculator gives $10^{0.52412} \approx 3.3428739$. So $N\approx 3.3428739 \times 10^{-1}.$
 
I provided a section of the table that is in the book.
 
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...
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...
