AI Thread Summary
To convert £0.91 into the old UK currency system, it equates to 18 shillings and 2.4 pence. The calculation involves understanding that there were 240 old pence in a pound, leading to the conversion of 91 new pence to old pence. The discussion also touches on the simplification of currency systems, referencing practices in Canada and Europe. The conversation highlights the complexities of pre-decimal currency while suggesting modern alternatives. Ultimately, the conversion illustrates the historical differences in currency representation.

Sir,
Would anyone be able to help me with converting the UK decimal currency amount of £0.91 to £ s d
Thank you in advance,
Regards,

In the pre-decimal currency of the UK, there were 12 old pence in one shilling and 20 shillings in one pound; thus there were 240 old pence in a pound. (Note that the symbol for the old (pre-decimal) penny is d whereas p is the symbol for the new (decimal) penny.)

If $x$ is the amount of old pence corresponding to 91 new pence, then
$$\frac x{240}\ =\ \frac{91}{100}$$
giving $x=0.91\times240=218.4$.

$218.4\ =\ 18\times20+2.4.$

Hence $£0.91\ \text{(decimal)}\ =\ £\mathrm{0\,\,18\,s\,\,2.4\,d}\ \text{(pre-decimal)}$.
 
EASIER if you do what we did here in Canada:
eliminate the **** penny!

Don't you have the problem that you don't know how many dollars there are in a dollar?
Easier if you do what we did here in Europe: only one Euro. :p
 
Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
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...
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...
