Wow, no kidding? There are THAT many caves in Tennessee? That sounds really cool.

I think the official count by the Tennessee Cave Survey is actually somewhere around 11,600. But we count anything at least 50' in horizontal length, or at least 30' deep if it's a pit requiring vertical gear, as a cave. And we're finding more every year.

may i inquire which Physics topics / authors you are studying assuming of course you have time for such whilst writing great code .

I've always wanted to actually understand General Relativity. The undergraduate degree that I did in Physics only covered Special Relativity. I've been going back to the original papers - Einstein, Minkowski, etc. for the physics, and studying Tensor Analysis from a few different books (M.L. Boas - general math, A. Lichnerowicz - Tensor Calculus, ...). At the rate I'm going, it will probably take me a few years to thoroughly understand the subject, but I'm in no hurry... 
Ditto for everything else. These are hobbies, so I have no deadlines.

do you have a copy of Gravitation (book) - Wikipedia[^] i use mine as a door stop as i have yet to finish Classical Mechanics (Goldstein) - Wikipedia[^] . it required several readings with an overly lengthy interruption in order to begin to understand virtual displacements as utilized in deducing LaGrange's equations . i have to read it again to consider if my understanding is correct .
re/ tensors i viewed a few years ago a superb YouTube series on the subject . unfortunately i no longer have the link .
also do you have a copy of "Spacetime Physics", Second Edition by Edwin F. Taylor and John Archibald Wheeler .
i also have a oopy of Einsein's GR paper . i did not find it helpful . the references to Mach and his ideas i have yet to understand .
i wish you great success in this fine pursuit .

I have a copy of Gravitation, but not the other books.
I have a copy of Einstein's GR paper, and am trying to collect the papers that Einstein referenced (and in some cases - the papers that they referenced). The problem is that many of them are available only in German - and I don't read German.

of course it may be useful to steady the original papers . however it seems to me you are eschewing the modern texts . if so i do not understand why . don't forget papers published in scientific journals are terse and not meant to be edumakational exempli gratia Einstein's original GR paper to now a 1,000+ page tome by Wheeler et al . also i am a believer in multiple authors / texts . by the way my undergrad physics instructor was kind enough to give to me the gift of a Xerox "orignal" copy of Michelson's "SPEED OF LIGHT" notebook complete w/ tea cup stains and his fine penmanship .

I didn't say that I intend to neglect modern treatments of the subject. I just want to start from the original papers, and take it from there. I know, for example, that in order to understand GR I must review Tensor Analysis, study Differential Geometry, etc. before even trying to tackle Einstein's papers, to say nothing of later texts.

I have apart time bladesmithing business. It is a hobby that got out of hand and now I make high end things for collectors.
Aside from that I'm on and off writing a book about DCOM and Windows Security for developers.

Chemistry. I turn water, grain, yeast, sugar and hops into beer.
Good stuff and only about $27.95 a bottle.

How large are the bottles? If they are standard beer bottles, that's pretty expensive beer!

Well, that was tongue in cheek. Point is that I don't make beer to save money. Don't really keep track of cost although many of the recipes are gifts from children/grandchildren. Besides, the alcohol content is high enough to remove worries.

I wouldn't be surprised if a first-time home brewer who want to do everything right, getting all the right equipment in place for his first brew, would end up with that price per bottle.
For his next brew, the price would drop to not much above half of that. For his third brew, probably below $10 a bottle. For his 50th, only slightly above the price of the consumable raw materials. Depending on how he obtains them, the quality, and how much processed they are (grain? syrup?) I wouldn't be surprised if he gets down to $1-2 a bottle.

True.
Basic 1 gallon beer making kit, including ingredients, jug, tubing, etc, is about $50. Makes 9-10 bottles (12 oz) depending on spillage. After that, the "recipes" ran about $16. This from first outfit I purchased from. The original kit was a present so, "free".
The last 18 gallons were from an outfit in Canada, each recipe makes 23 liters. I make 1 gallon at a time, so conversions are required. I brew like I programed: "Oh, about this much". The last batch usually comes up short. The yeast is a problem so I play government: I throw money at it, buying individual 1 gallon mix packets. SWMBO lays an eyeball on the hops and divides them into 6 portions (23 liters is "about" 6 gallons, 6.07). I like this outfit because the wort comes in a liquid which avoids the boiling process. It is the consistency of molasses. I use purified water, from reverse osmosis process ($1.20 a gallon). Please don't tell me they fill the jugs from the men's room.
So far, I have not purchased many recipes, mostly presents from relatives to keep me from bothering them. I have purchased bottles, caps, Capper, and hydrometer. So, my cost per bottle (so far) is actually negligible.
My beer runs about 6% alcohol and a gallon lasts a month or so depending on friends and relatives to help with consumption. I am not much of a "drinker" and the wife doesn't like beer (hooray). I have one friend who comes over about once a week and we have 1 beer, sitting on my patio, solving most of the world's problems. We are veterans and regale each other with war stories.
Difference between war stories and fairy tales:
Fairy tale: "once upon a time..."
War Story: "this ain't no stuff"...

Chemistry? I'm scared of chemistry! I'll just put it like this: I graduated high school with no missing fingers, somehow.
When I saw the word "beer" that's when I knew that I had to upvote your post.

It's been pretty much flat out work for me for the last 18 months - which is why I've not been on CP very often. But my contract is up and I'm planning on chilling for a few weeks.
So side projects have taken a back seat, but when I have the time, and energy, I can usually find some DIY stuff to keep me busy. But my "guilty pleasure" is US politics. Yeah, I know politics is a taboo subject on here - so I'll try to stay non-partisan. First of all, I should declare: I'm not an American and I don't live in the US - so I have no vested interest. But, ever since a reality TV show host got made President, I've been "rubber-knecking" like someone who can't take their eyes of a nasty accident!  There's plenty wrong with politics here in the UK, but our friends across the pond, take it to a whole new level.

I like to make tools and utilities to automate manual tasks.
That means spending a month creating a tool that can do a manual job that takes 2 minutes once a month. 
I hate command line stuff, so I build UIs around those to be able to use my favourite rodent.
And I get really annoyed by UIs that are sloppy. (outlining slightly off by 1 pixel  )
So I try to build them again, but better.....

Easy, peasy. I have a macro pad. Use it for VM passwords, most of the stuff I input to command line (Linux). About $50.

I used to do some coding on personal projects, but lost interest in messing with any significant coding outside of work.
Currently my main hobby is winemaking -- I have nearly 100 gallons in production, which will be bottled between May and November of next year. The fall grapes arrive in late September and October, so the cycle will start again.
