## Tattoos For the Math and Science Geek?1186

An anonymous reader writes "I've been thinking of getting a sleeve of math and science tattoos for quite a while now. With the money saved up, the only question remaining is, what equations/ideas should I get? I know for certain that I'm going to include some of Maxwell's equations, and definitely Ohm's Law. So, if you were going to put a tribute to the great math and science minds on your body forever, which ones would you choose?"

Personally, I've always enjoyed the beauty of Euler's identity [wikipedia.org], any form of Gaussian (normal) distribution which has a standard form here [wikimedia.org] and entropy in regards to information theory [wikimedia.org]. Of course, these are just personal favorites -- the last two because I am a computer scientist with so much college work hinging on them. You probably have personal favorites in chemistry or physics or another field even. Honestly, the loan formula [wikipedia.org] is probably one of the most widely used and life changing formulas in the United States today -- especially given the recent financial crisis. I think it would be best for you to draw up your own formulas in a geometric display rather than someone else's symbols. I suppose that would require extreme precision on the end of the artist and also introduce interesting problems with the elasticity of your skin ... but I'm one for originality especially if you're about to mark yourself in a relatively permanent way.

Tattoos hurt, they endanger your health, they are expensive, and most of all they are superficial. AKA they are for looks only.

OK, yes, they hurt. That's true.

As far as endangering your health, it means you're going to the wrong damned shop. Any tattoo place that doesn't have an autoclave, and single-use needles should cause you to flee. I've never seen an artist not using latex gloves, not using sterile gear, and not using ink in little disposable cup that get tossed when they're done. Any modern shop is actually very clean, and if it isn't, don't go there.

As to being purely superficial, lots of people get tattoos that have a strong meaning to them (and, admittedly, lots don't). Some people get tattoos so that other people can see them and say "wow, he's got a tattoo, cool". Others get them entirely for themselves -- you can't see any of mine unless I want them to be seen. You're making absurd generalizations -- if 40% of Gen-Xers are sporting ink, there's almost no generalization you can accurately make about why people get them.

Somehow I knew a story about tattoos on Slashdot would trot out a bunch of people who know absolutely nothing on the topic. Now everybody gets to make categorical statements they can't support with anything but opinion.

The scope for scientists is unlimited, the scope for engineers depends on the product.

Here's what Stephen Hawking has said he wants on his tombstone: S = (pi.A.k.c^3)/(2.h.G) It's the formula for the entropy of a black hole, also the maximum amount of entropy possible in a volume of space. It's interesting and extremely insightful into the nature of the universe because all the values on the right-hand-side are constants except for A (the area). So it says that the amount of entropy in a black hole, and also the maximum amount of entropy possible, is directly proportional to the surface area! This is very counter-intuitive and is related to the holographic principle [wikipedia.org].

Bile? I was just making an observation in somewhat colorful terms. And it annoys me when people justify fads.

I'm not justifying the 'fad' of tattoos. It took me 20 years of serious thought and waiting to get my first tattoo -- it's not like I jumped on the bandwagon and decided to get one last week. So, not everybody who gets ink is part of the 'fad'. Back in the late 80's, there were books like this [wikipedia.org]. Some of us have been aware of, and interested in, body modification for a long time.

"By choice, I don't have anything more extreme that is visible to anybody unless I want it to be."

So, you are ashamed of some of your tattoos.

No. Absolutely not. I carefully placed my tattoos where I could selectively hide or show them depending on the situation. For business stuff, I prefer they not be visible because some asshats will just not get it. If I'm in a swimming pool, well, you're gonna see ink.

Check and mate.

Ass and hole. Dick and Wad. Slap and Nuts. How about Jack and Ass?

And not only that, he's only got a "theme", not the content. If you have to ask for ideas, it's probably not something you've completely thought through.

Or he could make the "theme" the content of the tattoo itself. When I met the woman that later became my wife, I was instantly taken by her tattoo of ... a book. A symbol of learning. Not of any one bit of content you may have learned here or there, but of the process of learning in itself.

And yes, twenty-odd years later it's a bit blurry and splotchy and certainly doesn't look as pretty as back then - but the meaning is still there, as powerful as it has always been.

Nobody has to give you a job. If they don't like your 'x' they don't have to hire you.

Note that the employer is breaking federal law if 'x' is:

• race, color, religion, sex, age, ethnic group, or national origin
• disability
• genetic information
• association with or marriage to someone (on the basis of race, religion, national origin, or disability)
• previous discrimination lawsuits, or participating in discrimination investigations
• participation in schools or places of worship associated with a particular racial, ethnic, or religious group

States have innumerable laws such as can't make hiring, firing, compensation, layoff, transfer, training, benefits, retirement, or promotion decisions based on:

• status as a parent
• pregnancy
• results of a lie detector test
• marital status
• sexual orientation
• political affiliation

So clearly employees do have recourse for discrimination. Your "a job is a privilege not a right" is about a hundred years late.

Also, yes the first amendment only applies to congress (and state governments from the 14th amendment) but the question here isn't of law, it's of whether something is right or wrong. Freedom of speech is the defining principle of American culture and law, and its violation is rightfully greeted with disgust.

There's nothing wrong with a tattoo (especially a clever one) if it is well done and located where it can be either displayed or hidden as desired. Live a little, and don't worry about every single thing you do today being so significant as to possibly, maybe, some day, somehow completely ruining your life.

You don't think that some ideas or symbols are worth marking your body with?

I have a tattoo of the symbol for infinity on the center of my back. Any T-shirt covers it up so 95% of the people I meet haven't seen it and don't even know I have ink. I got the tattoo after thinking of the idea and considering it for 1 or 2 years. My Dad took me to the artist who did all of his tattoos right after my high school graduation ceremony, and paid for it as a graduation present.

I got the tattoo because the concept of infinity is closely related to immortality, timelessness, and endless life. It's ironic to tattoo a symbol for timelessness on a mortal body that will eventually wither, die, and rot. Therefore the tattoo is a personal reminder to live life to the fullest because it doesn't last forever.

The tattoo is not a cheap joke. It's not a kitschy idea. I don't show it at parties to get a laugh out of people. It's a very personal reminder to be happy and enjoy life.

You're right that it's very important to consider that tattoos last for the rest of your life (but not forever), and that they will eventually fade and possibly be warped by the wrinkling and sagging of skin. It's important to think about a tattoo for a long time before getting it to make sure that you want it, and it's also important not to get a tattoo of some political or scientific position you have that might change in the future. A tattoo of a flower is simple and timeless; flowers will always represent life, love, and beauty, and the tattoo could mark some important life event (such as my high school graduation). A tattoo that says "Bush Sucks" or "Jesus Saves" might not be a good idea because you might not always feel that way.

So, in summary, some tattoos are indeed stupid, but the idea that getting a tattoo is inherently stupid is a stupid idea. I'm not worried about my tattoo fading or wrinkling because it's a tattoo about aging and death anyway; the whole point is that it won't be there forever. The next tattoo I'm going to get will simply read "no hope, no fear" and I've been sure that I want it for over a year.

Tattoos 50 years ago were about getting drunk while in the navy.

And don't forget: the reason why you did that back then was to prove what a Real Tough Man(TM) you were.

I'd love to see what those 70-year-old guys think now that half the teenage girls they see have more ink than they do. I knew a number of middle-aged guys thiry years ago who had got tattoos when they were twenty years younger, and they all felt kinda stupid about it then. By now they must feel unbelievably stupid, because they realize that what their younger selves considered a mark of manly toughness was no big deal, since virtually everyone has more than sufficient pain tolerance to get inked.

Tattooing as a practice has been around forever, usually as a means of expressing some aspect of social status, mostly among men. So while tattooing is certainly not a fad, the current "express your unique identity via a tattoo" certainly is, just as the "express how manly and tough you are" was.

Hopefully when this fad passes people will realize that tattooing is no big deal, one way or another. It can be useful for people struggling to express their identity, but it says mostly, "This person went through a time in their life when they were sufficiently uncertain of who they were that they felt the need to spend money and time and a trivial amount of pain on ensuring some aspect of who they thought they were at the moment would be emblazoned on their skin."

People who are secure in their identity don't need to do that. For some people who aren't secure in their identity it can genuinely help. For most, it's treating the symptom, not the cause, and that's rarely a good idea.

He's making a joke about how it's regarded as incorrect. However, he doesn't really know what's he's talking about ;) The Brontosaurus is widely held to not exist, by the non-paleontologist community. There are two reasons: The first and most commonly held reason is that the original Brontosaurus reconstruction was a composite, and got the head pretty wrong. However, this was resolved a long time ago, so unless his tattoo from the 90's is from the 1890's, I'm sure he got the head right. (Besides which, creating composite reconstructions when bones are missing is an acceptable practice in the field, so long as you acknowledge this fact when you publish! Brontosaurus is not the first, nor the last, dinosaur to have inaccurate reconstructions at some point. Many dinosaurs even today are best-guess composites). So, though the Brontosaurus might not have looked like the earliest drawings (from 100 years ago!) it still existed. The second is an issue of taxonomy. Brontosaurus's original scientific name was Brontosaurus Excelsus. However, in 1903 it was argued that it's not different enough from the Aptosaurus genus to get it's own genus. So, the scientific name was changed to Aptosaurus Excelsus, instead. However, Brontosaurus was already in the lexicon. So, that became its common name. Within the field, Brontosaurus is an accepted synanym, though the scientific name is preferred (as always). Nobody would laugh at my ignorance if I claimed to own a cat, rather than the "correct" term "felis cattus", though in a scientific paper the scientific name would be preferred. In 1989 there was a bit of a stink over the USPS putting a "Brontosaurus" on a stamp. People said it promote scientific illiteracy to put the wrong name on the stamp. However, this is no more incorrect than putting a Bald Eagle labeled "Bald Eagle" (rather than "Haliaeetus leucocephalus") on a stamp. Outside of a scientific settings, there's nothing wrong with using the common name of a species. (And, in fact, Brontosaurus Excelsus is still an accepted synonym for the scientific name). Even in a scientific setting, it's usually not frowned upon to use the common name, once you've used the scientific name to make it clear what species you are writing about. One might put "felis cattus (cat)" and from then on refer to them as cats, without complaint.

Depends what two weeks of the year you are there. And what type of "farm" it is.

From what I've seen, even if you do 10,000 acres of grain (be it corn, wheat, beans, etc) there are DEFINITELY times of the year when you don't do nuthin.

Of Course, the planting season and the harvest season are pretty busy (24x7 if you can).

But, if all you do is grain, there are some times when the most difficult thing you do is going to your favorite breakfast joint to drink coffee and tell tall tales.

The hard kind of farming is when you deal with livestock. Those kinds of farms.... Yeah. It stinks. Literally and figuratively. Having livestock makes it hard to get away on vacation - ever, it's a dawn to dusk type of career. No, I'm not a farmer, but I live in farm country and I have a lot of friends who are farmers or grew up on farms. Most grain farmers have some sort of livestock though, from what I've seen. Until they want to slow down when they get old, then they sell off the livestock. Yes farming is hard, but it isn't torture, and it can be very profitable.
