AI Thread Summary
To convert miles per hour (mph) to meters per second (mps), start by recognizing that 1 mile is approximately 1.60934 kilometers, and 1 kilometer equals 1,000 meters. Therefore, to convert 40 mph to mps, first convert miles to kilometers, resulting in 40 mph being approximately 64.37 km/h. Then, convert kilometers per hour to meters per second by dividing by 3.6, yielding about 17.78 m/s. The final conversion shows that 40 mph is equivalent to approximately 17.78 m/s. Understanding this conversion is essential for solving related physics problems.

It actually applies to helping me in Physics but its math related. I can't for the life of me for some odd reason, remember how to use the monorail method so convert something such as 40mph into meters per second. Where the hell do I start?

miles/hour = 1.6km/hour = 16000m/hour = 16000m/60minutes = 16000m/3600 s
= 4.44 m/s

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...
