There’s been a thread on rec.arts.comics.strips about the value of maths education, and how much of the things you learn in maths class are really useful later in life. Brian Fies contributed a personal essay so profound I asked him for permission to reproduce it here.

I like doing square and cube roots on a slide rule–you don’t even have to
slide anything, just read the line on the proper log scale. That’s
probably one of the few instances where a slide rule remains easier to use
than a calculator (though as Mark says, not as accurate), and I think it
instills a good subconscious feel for what logarithms are all about.

To the original question of Why Bother Learning Math: Y’know, I really do
find myself using math up through at least the high school level very
regularly. Calculating square footages of flooring, what volume of topsoil I
need to cover a yard, what length of PVC pipe to buy, how many bookshelves
to build. Figuring averages, tips, gas mileage, food unit pricing. Once in a
while I bust out the Pythagorean Theorem or the volume of a sphere. It
actually is part of the fabric of my life that makes me a better consumer,
homeowner and citizen.

What I didn’t really get until I hit calculus in college is that math (and
physics) are more valuable to me philosophically than as nuts-and-bolts
problem solvers. There quickly comes a point where equations stop being
about turning a crank to find “the answer” then modeling how an idea or
physical phenomenon works. I don’t think I actually solved a single
calculation or equation for at least my last two years of university study.
For example, you don’t take Schrodinger’s wave equation, put in some
numbers, and get an answer of “42.” Rather, you take that equation and ask,
“What does it tell me about how a hydrogen atom might act?” and then go see
if the atom does that.

Even though I don’t use that level of math or even remember how to do it
anymore, I don’t consider that education a waste. It changed the way I look
at the universe and trained my brain in ways that have been beneficial to
me. One example: calculating hundreds of integrals from zero to infinity
gave me the habit of looking at the extreme possible outcomes of situations:
what would happen if everybody did something; what would happen if nobody
did it? What if the opposite action were taken (i.e., integrating from
negative infinity to zero or positive infinity)? What if that awful thing
done by the Democrats had been done by the Republicans (or vice versa)? What
if a policy that applies to black people were applied to whites? Or women to
men? Would I feel differently about it? Should I?

Plugging in zero and infinity to see what happens is a helpful way to
analyze a math problem and I find it a helpful way to analyze life, as well.

So, if you ever wondered to yourself, “why do I need to learn this stuff anyway”, that’s why.

bunny_hugger, who I know from else-Internet, had this to share on New Years:

On Christmas Eve, I watched Scrooge, the 1951 version with Alistair Sim. This is not only my favorite holiday film, it is one of my very favorite films. As I watched it, I realized that part of what makes Sim’s portrayal so great is that he doesn’t overdo his portrayal of “mean Scrooge.” You can still see flashes of the kinder man that Scrooge once was, and this makes it more believable when he transforms into “good Scrooge” at the end of the film.

This ties in with something I have been thinking about a lot lately. It seems to me that people almost never really change — at least, not in the sense of becoming an entirely different person. Instead, I think that people become better or worse versions of what they already are. People’s essential personality traits generally stay the same; but what they put those traits in service of, and which traits come more to the front, will change over time.

With that in mind, I offer this New Year wish. I wish that all of you will become a better version of yourself in the New Year. And I hope, and resolve, that I will do the same.

Something to chew on.

Courtesy of aolscalzi, I found the article from the AARP (formerly the American Association of Retired Persons), titled 50 Things You Need to Know by 50.

Now, you might think the AARP is going to serve up a lot of stodgy, get-off-my-lawn advice, but given that their very first tip for life includes “Do the dishes naked.”….

Engelbert Humperdinck offers advice for Karoke that’s just as apropos to filkers:

In karaoke the most important thing is to pick a song by someone you really admire, and take the best of that person while giving the song the best of you. If you are not a singer but want to be part of the fun, pick a cheeky song and act silly. If you can’t even catch a melody, let alone carry one, just speak the lyrics. Pretend you are Richard Harris.

There’s also advice from Star Trek veteran George Takai, Iron Chef Masaharu Morimoto, and basketball legend Kareem Abdul-Jabbar.

Seriously, there’s a lot of good thoughtfood here. Go eat.
