Re: Linear Interpolation FP1 FormulaVery good that you are relaxing. What is the weather like there? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11677 20130707 17:32:22
Re: Linear Interpolation FP1 FormulaNice and warm, 26 degrees has been the highest so far. Haven't been out much, waiting for my book to arrive in the post so I can go out and do some maths in the heat of the summer. I heard that it is very hot where you are on the news? #11678 20130707 17:37:21
Re: Linear Interpolation FP1 FormulaYes, record breaking. They said 118F. I went outside with my digital thermometer which is accurate to .1° It read 122F. The hottest I have ever known was 119F. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaAnd a lot of people are dropping like flies out there too, I heard? #11680 20130707 17:40:08
Re: Linear Interpolation FP1 FormulaI have heard of 1 fatality and a bunch of people who are suffering from heat stroke. That was 3 days ago, could be more by now. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaThat is terrible. And it is only going to get hotter apparently. #11682 20130707 17:45:16
Re: Linear Interpolation FP1 FormulaYes, that is what they are saying. The worst thing will be when the power gets overloaded. Then we will have a blackout. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaSounds like a nightmare. And Brits are complaining at anything higher than 20... #11684 20130707 17:52:58
Re: Linear Interpolation FP1 FormulaOver here in Seattle they had a record 93F which is 6 degrees higher than their maximum. A heat wave is relative. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaYes, and 20 degrees in Britain is nowhere near our maximum. #11686 20130708 06:29:08
Re: Linear Interpolation FP1 FormulaBy Spiegel? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaWhat about it would you like to know? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11689 20130708 07:29:29
Re: Linear Interpolation FP1 FormulaDo you think it gives a good treatment of the topics it covers? #11690 20130708 07:32:49
Re: Linear Interpolation FP1 FormulaThere are some numerical errors in Spiegel's books. They are good for problems and cover some topics that are difficult to find elsewhere. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaMy copy just arrived in the post; I had been scrolling through it online over the last week, I find it quite accessible. There are a lot of typos though, as you pointed out (for a third edition, much more than one would expect). #11692 20130708 21:44:04
Re: Linear Interpolation FP1 FormulaHe has other books too and they have obvious typos but it is still a pretty good book. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11693 20130708 21:44:53
Re: Linear Interpolation FP1 FormulaI agree, lots of questions and examples making it easy to follow. #11694 20130708 21:53:01
Re: Linear Interpolation FP1 FormulaHis finite difference book is one of the best ever done. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11695 20130709 19:31:48
Re: Linear Interpolation FP1 FormulaDo you mean his other Schaum's book on Finite Differences or another one? #11696 20130709 19:35:24
Re: Linear Interpolation FP1 FormulaNever mind, he only wrote the Schaum's one, right? Amazon showed two but they were actually the same book. #11697 20130709 19:48:46
Re: Linear Interpolation FP1 FormulaHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Linear Interpolation FP1 FormulaGot them half done so I am taking a break. In mathematics, you don't understand things. You just get used to them.
