Interesting Physics and Math Stuff

I was fortunate enough to teach physics this summer to advanced undergraduates making their way to medical school. One thing that struck me was how how much teaching has so much in common with consulting. ...

This is still in draft mode The Historical Context of Data Collected Unless we look at the ‘context’ of the data that we collect, we may be missing the big picture. The Case of the top ranked Universities in the U.S. The Case...

Selecting a truly RANDOM Sample If you choose every person who passes you on the sidewalk, that would not be a random sample, since you would miss out the people moving in vehicles. If you, likewise, stop every car on the...

The ‘Tired Photons’ Hypothesis The ‘tired photons’ hypothesis is in direct contrast to the Doppler hypothesis. It states that as photons travel through space, they experience collisions with interstellar...

Also see my – Problem Books for Pure Math, Physics and Mathematical Physics If you are looking for some of the most important, yet elegant math proofs, look no further than these two books. The first one – Proofs from the...

I had a lot of trouble distinguishing between continuous and differentiable and analytic functions… Analytic An analytic function is a function that is smooth (in the sense that it is continuous and infinitely times...
