AI Thread Summary
To calculate the conversion rate of particles, one can determine the average rate of change over a specified time period. In this case, with a decrease of 4 particles over 5 seconds, the average conversion rate is -4/5 particles per second. It's important to note that this calculation assumes a constant rate of change; if the conversion is exponential or varies, the rate may not be accurate. The discussion emphasizes that simply reading the particle count isn't sufficient for precise calculations. Therefore, the average rate of change provides a basic estimation of the conversion rate per second.

I had x particle. After 5 second due to conversion it came down (x-4) particle. Now, how do i calculate conversion rate/sec?

you can't determine the conversion rate with just reading.. chances are there of going wrong, if its an exponential or depending upon the initial quantity. othrewise its normal way (-4 particle /second)
 
The best you can do is find the average rate of change over 5 seconds by dividing by 5 seconds: the net change was -4 particles in 5 seconds so the average rate of change is -4/5 particles per second.

If you have reason to think the rate of change is constant, then it is -4/5 particles per second.

(I think abluphoton miswrote and meant "-4 particles/ 5 seconds" which is -4/5 particles per second.)
 
correction i should have told [-4/5 particle per second]

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...

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...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
