This is such an important result & yet doesn't seem to be a widely known result. Your proof is very well done. You should consider publishing it in CMJ. Or if you don't mind, I'd be happy to rework it & send it in :) Thanks for writing it up.
- yummyfajitas 10y agoI'm not familiar with CMJ but happy to discuss the idea. Write to me, email is in my profile. As a paper it would be significantly stronger if it did the binary case, though.
- dxbydt 10y agoHey thanks! I prefer the CMJ (http://www.maa.org/press/periodicals/college-mathematics-journal/the-college-mathematics-journal http://www.maa.org/press/periodicals/college-mathematics-jou...) to AMM etc. because your proof is ultimately undergrad math - some calculus, complex analysis, change of coords and inequalities. It's a pity the CMJ is not as well known. My professor used to circulate copies in class and we learnt more from it than from the grad journals which went out of the way to make things abstract. You also have a fantastic blog on Harris Benedict equation, which I have combined with an ML approach on WeightGreat - truth be told, this was one of those miracles that happen when you read Hacker News regularly. You find someone has worked on the exact same problem you are interested in, using a different approach, and you can combine that with your own insight to come up with a very promising idea.
- yummyfajitas 10y agoI'll take a look. And send me an email, what you are doing sounds interesting, would love to learn more.
