I hear there is a biology professor who won't write recommendations for creationist students. I wanted to comment in general:
If I ask Joe Dirt to write a recommendation letter for me, he is perfectly right to refuse. People needn't write letters for anyone they don't want to.
However, in a school setting, students are required to have these letters. And professors are expected to write them. Refusing to write students a letter hurts them. And such a blanket refusal is morally wrong.
Refusing letters over a student holding some theory, only makes sense if the theory directly interferes with the student's studies, and makes her/him significantly (meaning "enough to matter" not "lots") worse at them. This basically means refusing letters for incompetence (math major who thinks 2+2=5; politics major who thinks "democrat" is a type of fish).
So what about biology and creationism? Well, if you want to be a doctor, you learn how human beings are, and about medicine, and it doesn't matter. If you want to be a vet, and you disagree about why vestigial organs exist, but know the same facts about them, it again doesn't really matter. If you want to be a zoologist, and study the evolution of animals, it does matter.
So my view is, to be moral, the biology professor must refuse recommendations on a case by case basis, and only in very specific circumstances will refusal for belief in creationism be acceptable.
In base 2, 19 is 10011. In base 1/2, 19 is 1.1001
In base 10, 19 is 19. In base 1/10, 19 is 9.1
The trick is to write the number in reverse, and in the fractional version, put a decimal point after the ones column. This is because decimals have negative exponents, so the fraction gets flipped.
Fractional bases that aren't 1/something seem like a real mess to use.
Also, I wanted to count in balanced base 3. I will use -, 0, and + for my digits.
+ +- +0 ++ +-- +-0 +-+ +0- +00 +0+
You'll notice that you *can* count be incrementing the one's column repeatedly. You just have to remember to reset things to - not 0, after they overflow.
Will count from -1 to -5 now:
- -+ -0 -- -++
Notice it's the same as positive, with the -'s and +'s reversed, and 0's untouched. And you can count by decrementing the one's column, and when it overflows, decrement the next column and reset things to a +. I guess I should point out that you can add as many leading zeroes as you want, which is how decrementing a column that doesn't exist works.
After a comment on the last entry, I will now work out a bit about numbers in base -2. To start, I'll convert a random number to base 10. 101 would mean: 1*(-2)^2 + 0*(-2)^1 + 1*(-2)^0 or 5. From right to left, putting a 1 instead of a 0 is worth 1 -2 4 -8 16 -32 64
So, to get the number 2, we have to write -10. It seems very confusing, on a human level, that using a minus sign has nothing to do with whether the number is negative or not. I guess a computer wouldn't care about that, except that we often work in positive numbers, and can use unsigned numbers to save space.
Now I'll count to 10 in base -2:
0001 -0010 0111 0100 0101 -1110 -1001 -1000 11001 -1010 which is really jumpy, and a total mess for humans, and it's very strange to need more digits to write 9 than 10. I think it would be slow for computers to do addition with this. In positive bases, using digits from 0 to base-minus-one, adding is nice, because you just increment the one's column repeatedly (and each time it overflows, reset it to zero, and increment the next column). There are tricks, like if you have two numbers in the same base, you can add various other columns directly to each others. There may be tricks with base -2 also, but I still bet it's inefficient, because you can't just increment the next column when one overflows.
I was just considering posting some jokes as an entry. Many of the jokes I like are, to some people, offensive. Blonde jokes, dead baby jokes, religious jokes, racist jokes -- these don't go over well with everyone. And I want readers, lots of readers. So, unsurprisingly, it occurred to me that posting the jokes might be a bad idea. Of course, if I don't post anything that might be offensive, I'll never post anything interesting. So what should I do?
There is a moral principle that tells us, if we imagine some stone-age people, who want a society with lots of washing machines, their best bet is not to campaign for them, and try to invent them, but rather to become capitalists and try to act morally. Similarly, the Arab world, if it focussed more on acting morally than acquiring weapons, would have more weapons than it does (just like the US has lots). Of course, in that case, the Arab world also would not want to use them to kill civilians... Also similarly, if one wants to be happy, one should not focus on trying to become happy directly, but should try to act morally, and happiness will come as a side effect.
If I want readers, I should not focus on how to get readers, but rather on creating a good blog, which means writing what I want and like.
Even if we imagine in the limit cases with perfect foresight and calculation, a focus on morality would still be superior to a focus on readers. Either, they would be the same, or the readers approach would result in more readers ... at the cost of acting badly, and I certainly don't want readers that much.
As to jokes, as I'm ambivalent about posting them, I won't for now, but may later.
Humans live by their creativity, not by devouring limited resources.
People twist their factual views to fit their moral views, not vice versa.
Some people don't value anything. (This is often associated with the left wing. Offense intended, but not to any particular person.)
These people often adopt pseudo-values to hide this, from themselves and others. Pseudo-values have an appearance of being values, but are not. One way to spot pseudo-values is they can be applied without thinking. An example is pacifism, which states that all violence is wrong, period.
Pacifists, of course, oppose a war on Iraq. In Iraq, every day, people are tortured, which pacifists must consider to be wrong. Yet they refuse to do anything about it. The problem is, if they did not turn a blind eye to such suffering, their "values" would fall apart. They would have to support a war, and could no longer be pacifists. But they also cannot be good people, who support freedom and liberty and such, because they do not value those things, or anything else, and do not understand how any else can either. And so they cling to their pseudo-values.
Here are some other "values" that are often (not always) shams:
- Save the environment
- Feed the hungry
- Equality for all
- Loving one's family (Notice how mechanical it is. Simply determine if someone is family to decide if there is love.)
- Collateral damage is always wrong, because it hurts people (A pacifism variant. Easy to apply mechanical, just determine if anyone will be hurt as a result of action X, then oppose X.)
- Guns kill people
- Raise school standards
- Won't someone please think of the children!?
- Save the sea snails from extinction!
- All actions have to be UN approved.
- Curse words are bad.
- TVs ruin our minds
