Wait, teenagers know about sex? When did this happen?

The Bush administration has been focusing on abstinence as the only one hundred percent effective way of preventing unwanted out of wedlock pregnancies. Spending federal tax dollars on preaching this message to minors is bad enough, in my mind, and the 18-29 year old crowd is being added as targets of this message since the problem of out-of-wedlock pregnancies for that age group is large. I see two logical flaws with this approach. One is that if abstinence is the only 100% effective way to prevent unwanted pregnancies, and pregnancies are a risk one takes when choosing to take part in unnecessary and risky behavior (sex, that is, if you don't remember what you learned in middle school health class), what is preventing that logic being applied to other unnecessary and risky behavior. High school sports come to mind. Any kind of contact sport (though according to my brother, dancing is a contact sport, football and lacrosse are impact sports) carries a risk of injury. If the only 100% effective way to prevent unwanted concussions and broken bones is to not take part in sports, why are these sports encouraged? I guess team-building and physical fitness are some of the benefits of doing sports; however, there have been a few studies showing that encouraging aggression on the field translates into more aggression in other aspects of life, so there is at least some detrimental social impact from sports like football, etc. In addition, frequent sex has been linked to improvements in mood and mental composure. What it seems to boil down to is that society deems sex out of wedlock to be immoral, while sports to be wholesome, to hell with the evidence. This argument could be continued indefinitely, it seems, and probably neither side would be able to convince the other. So even though the internet is the perfect place for such an indefinite argument, I'm not interested in having it. So on to my main objection (math warning).

In practice, abstinence is 100% effective, while contraceptives vary in effectiveness, but tend to be good and can be combined (if a condom is 90% effective, and the pill is 98% effective, a combination of the two should be 99.8% effective.) Abstinence is in the lead. However, public policy is not directly tied to sexual behavior. There is a barrier: the effectiveness of education. Assuming that abstinence only education is 90% effective, and contraceptive education is 95% effective (both probably off, but in my mind fair guesses), then we have to tie in these numbers to get the actual expected risk to the population. With these numbers, abstinence only education would be, in the end, 90% effective (90% of the time it works every time, 10% of the time it never works), while contraceptive education would be 94.81% effective (95% of the time it is 99.8% effective, 5% of the time it never works.) While touting the message that abstinence is the only 100% effective behavior to prevent unwanted pregnancies, it may be the case that contraceptive education is more effective than abstinence-only education (using my numbers and a slew of other assumptions.) So until we know the effectiveness of the various methods of education, relying on the assumption that people will behave in accordance to whatever way we educate them is unfounded, risky, and may lead to a less effective public policy towards sex.

Time Machine, revisited

In June of 2005, I posted about an idea I had about sending information backwards in time. This morning, I got IMs from Tim and Ben pointing me to this article in which John Cramer, a physicist at the University of Washington, is performing an experiment testing what I proposed. It's not the exact setup I described, but the basic idea is the same: you perform an observation at some point in the future on an entangled photon which will determine how the entangled photons pair behaves when you observe it in the present. If you do one thing to the future photon, the present photon behaves like a particle (the superposition collapses before observation) and if you do something else to the future photon, the present photon behaves like a wave (the superposition collapses at observation). My first reaction was that he stole my idea, which is obviously not likely. I then found this article, written in 1997, describing the foundation of the experiment. So he beat me to the punch, but I still feel good about getting the idea in the first place.

California

My job sent me to California again. This is the second time I've been sent out on business, and the second time it has been to Pasadena. And guess what? Next week, I'm going back for another meeting. Three business trips, three times to Pasadena... At least the weather this time was much better; the last time I went it rained the whole time. This was much more like how I would expect southern California to feel.

I went for the 38th annual DPS meeting. I sat behind a table, talking to the occasional passers by, but mostly took advantage of the fact that a bunch of other people from the PDS, not just the SBN, who work elsewhere in the country were there, and I got a bunch of good ideas for my search engine.

Thursday night I went out with my boss, Bill Knopf, the head of the PDS, and a few other coworkers. We went to pick up Bill's friend, Rob, who has a recording studio on Los Angeles, and while we were at his house Stevie Wonder came by to pick up a hard drive (Rob handles Stevie's music hardware.) Stevie Wonder was suprisengly interested in astronomy, and we were all trying to figure out in our heads the math for the distance, speed and time of a few space probes. After Stevie left we got a tour of the recording studio, which was in this guys house, and it was impressive. I didn't bother counting how many computers, keyboards, sequencers, mixers, etc. he had there, but there were a few rooms full of the stuff. After the tour, the executive vice president of Sony came by to pick something up, and we talked with him for a while about the computer animation software they're using, particularly the "fur algorithm" used in open season. Unfortunately he didn't reveal any trade secrets I could go sell to their competitors. After he left the rest of us went to dinner, a good restaurant but an anticlimax from the rest of the night, and talked mostly about music... turns out basicaly everybody I work with either plays some instrument, conducts, or in some way does music-stuff in their free time. Go figure.

Friday afternoon before my flight I went to visit Allison, a childhood friend (her parents and my parents are friends, and we used to all go to the outer banks every summer when we were kids.) She's going to law school at UCLA. We got lunch, caught up for a while, then I had to go catch my flight.

I got sick at some point on this trip, and flying with a cold did a number on my ears. I'm just getting over it now, so I'm not looking forward to next weeks trip.

Dinosaurs had scales

I was bored, and remembered back from my days of music theory that there are a bunch of different 7-tone scales, more than just Major, Natural Minor and Harmonic Minor. I don't really care about all of them, so here's the short list of ones I was thinking of. On a piano, starting on the following notes and hitting the 7 following white keys (no sharps or flats) gives the following scales:

  • C Major

  • D Dorian

  • E Phrygian

  • F Lydian

  • G Mixolydian

  • A Natural Minor

  • B Locrian


Now on to dinosaurs...

In my psychology class, the teacher was talking about evolution. The first thing that caught my attention was his discussion on heart disease (we'll get to dinosaurs in a minute). He said that the reason humans are susceptible to heart disease now is that for a long period of human history we weren't living very long. The average lifespan was probably somewhere in the 20s or 30s. If heart disease doesn't set in until the 50s or 60s, then nobody would be living long enough for that to be a problem, so we never bothered evolving to be less vulnerable to such a fate. But, now that we are living to be old enough to encounter the problem, humans may wind up evolving wider coronary arteries that are harder to clog, or something along those lines. (He didn't mention that, while we weren't living that long, we were also much more active and probably ate less fatty foods, but that's not a big deal.) What bothered me is that, while yes, people are dying of heart attacks, most people have them when they are old and have already had children, so the genes are already passed on. This sort of thing is called a selection shadow, and it sort of shows that he should stick to psychology and stay away from biology.

The other thing he said, that really got me, was about how human memory evolved. He said that our early ancestors probably had worse memory than us today, and our memory today still isn't perfect (though, his idea of perfect is also flawed, ignoring the concept of efficient storage of relevant facts instead of brute-force perfectly-photographic memory.) He then, in his infinite wisdom, went on to say that a probable reason for this was that humans with better memory could remember where dinosaurs tended to hang out and avoid them. My professor suggested that humans had to avoid dinosaurs. DINOSAURS!

And people are surprised that, in the beginning of a college evolution class when the teacher asks for a show of hands who thinks that humans and dinosaurs coexisted at the same time period, a significant portion of students raise their hands. (true story)

I'm going to go drink heavily and hope to forget this.

Theft

I saw a few articles recently that I find somewhat disturbing. The gist is that the police can confiscate your property if a crime might have been committed, even if the courts find you innocent.

Police property: It’s finders keepers in NH

Federal Appeals Court: Driving With Money is a Crime


Any lawyers feel like weighing in?

Shitty Birds

So I need one of those fake decoy owls, or a real owl that I can keep on my balcony. Birds seem to think that the railing and chairs on my balcony are good places to perch and expel waste, and I disagree. It hasn't been a problem until now, so my only guess is that the birds are coming back to College Park for spring semester classes... because birds never migrate or anything.

Lazy like a fox!

So I haven't posted in a while, nor am I going to post much here. I'm starting a blog for beer recipies, food recipies, and really, recipies for anything you consume. My figuring is that between Tim, my Dad, and me brewing beer, me trying to learn how to cook, and (from what I hear), Tim's dad developing an interest in wine making, we should be able to get a decent number of posts... better than codemill at least. I need a better name, since now it's only beerandfood.blogspot.com, but all of the simple names I could think of were taken (by people who had one post, total, back in 04 or 05.) So, if you're interested in getting setup as a contributor, let me know and I'll try to figure out how to do all that.

I'm making the blog on the new blogger (beta.blogger.com) since, for a while, that was the only site I could access. See, my blogger and gmail logins were the same, so when I went to log into blogger it found a gmail account with that login/pass and figured I was logging into the beta site. That meant that I had no way of logging into the old site, which meant I couldn't post here. I just fixed it, so I'm back. Hooray!

Beer and Cheese

Went to the Baltimore Zoo on Saturday with everybody, and most of the beer I had was of good quality. I, uh, entered a cheese eating contest. Only because Tim and John were doing it and I didn't want to appear weak... and I'm stupid... and I like cheese. There were 10 guys on stage and we were each given a block of cheese (me? Pepper Jack) and two minutes in which to eat it. One guy launched his cheese into the crowd while trying to open it. I tried to stay calm and not stuff my face, and my approach worked: I won... two tickets to Six Flags... and the free block of cheese I just ate. I almost lost it twice but managed to keep everything down. I got passing comments for the rest of the day from strangers... things along the lines of "This guy likes cheese!" and such. My parents should be so proud.

grocery list: sponges

Moving out of the old place was quite the ordeal. Having the keys to my new place for a couple weeks before moving out of the house in Laurel made the move easier than it could have been; I got to move a lot of my stuff (books, clothes, etc.) before the actual move. On the Friday before the move I brought as much of my small furniture as I could, leaving only my bed, a couple couches, a table, and a book case for when we had a moving truck. Saturday morning Tim and I went to pick up the U-Haul and first loaded my stuff. Parker and Tim then came down with me and helped move stuff up to my apartment. A couch and the book case proved difficult to fit into the elevator because Tim and I, the people carrying the heavy furniture, couldn't figure out how to get a couch that is too long to slide in the elevator upright, and too long to just tilt and slide in to fit into the elevator. Parker (the nurse and, in my mind, less mathematically/geometrically inclined, suggested we slide it in upright and then stand it on its end once it's in. This, in hindsight, should have been obvious to Tim and me, but we're dumb, and Parker is smart. Once we got all the furniture moved in my brother called. He was supposed to help out, but didn't think we would start as soon as we did, so he came back to Laurel to help move Tim and Parkers stuff. They had a lot more stuff than I did, probably because there is two of them and they weren't moving as much stuff beforehand. We filled up the U-Haul, and two vans, and drove up to their place in Columbia. They have a 3rd floor apartment in a building with no elevators, so we had to move everything up two flights of stairs. Pushing a couch up two flights of stairs is hard, and it's even harder when you try it after spending most of the day tiring yourself out. Either way, everything was moved up, and Tim, Jeremy and I went back to Laurel to deal with the carpet people.

We have to get the carpet cleaned before leaving since there were animals in the house, but I didn't do anything with the carpet cleaners; Tim took care of that and can write about it on his blog if he pleases. If not, you'll have to be content with just the knowledge that we got the carpet cleaned. I know, I know, you want to read more about it. "Write a book!", you say. Perhaps some day, when I'm old, I'll write a memoir with a title like "Having the carpet in my old house in Laurel cleaned." or "What it's like to have a roommate talk to carpet-cleaning people." but until then, rest easy and know that, somewhere, a carpet is now cleaner than it once was.

Once the move was complete (more or less) a bunch of people came over to the house for a party. Keep in mind that there was no furniture, and we couldn't walk around on the carpet. We hung out in the kitchen mostly, and somewhat on the deck, then slept on the floor in sleeping bags.

Sunday, after cleaning up the rest of the house, I drove down to my new place in College Park and started unpacking and arranging furniture. This has been going on since, and I'm more or less happy with how I've arranged everything. I still need to get a coffee table (I think I can take my grandfathers old one that my parents are holding on to), a TV (assuming I get one) and a few more things for the kitchen. I've gone out and gotten a lot of things for my kitchen, both food, and tools for working with food, and at this point I'm only in want of some knives and maybe a mixer. I still haven't cooked a real meal. I've made dinky things like omelets, grilled cheese, and soup-from-a-can, but maybe this weekend I'll bake some bread or have my family over for dinner.

I have no internet at my place yet, and if I wasn't so busy shopping for the kitchen (damnit, I need sponges), this would mean that I would have time to read. Maybe now that everything is more or less taken care of I can read. Or maybe I can call the cable people and get some cable-tv and internet setup.

I'm probably forgetting things here, but chances are that the things I'm forgetting to write about, much like the things I have written about, aren't interesting enough to expect people to read about.

Oh, one other thing, people need to come see my place. I have food, and alcohol, and places to sit. What more could you want? Maybe after finals are over (so, next weekend) I'll have a small party where people can come over and make comments like "dude, where are your sponges" or "you should get a coffee table."

Chris Bliss

Do you like juggling? How about just watching people juggle? How about watching someone do an impressive juggling routine to the tune of "Carry That Weight" by The Beatles? Most musical-juggling-link salespeople would charge $50 for such an offer, but for a limited time, it can be yours for $20. Too expensive? How about $10? Ok, ok, it's yours for free. But the next one's going to cost you. How does your first born sound? Ok, ok, second born.

Stress

This week is not going to be fun...

I have a paper due tomorrow for my Philosophy of Language class... about ambiguity. It's about half done, and I'm not too worried about getting it finished on time. After class I have a teleconference with some people out at JPL, maybe my old boss at Goddard, and maybe a boss or two here in CP. It's about the status of this project JPL's working on that they want us to develop. It meshes well with my search engine, but I haven't had much time to work on it. It's been on the back burner partially since I've had a presentation to prepare for.

Oh yeah, I have a presentation on Thursday for my search engine. I've been putting some finishing touches on it, and trying to get the database it pulls the results from filled with good data, so it'll probably be ready. I still have to prepare a presentation, though, which means that some poor sap (tim?) is going to have to sit through a dry-run.

Friday, I have a meeting with the people I work with. This meeting doesn't scare me. It'll basically be a recap of the earlier meeting and my presentation, and other people talking about what they've been up to.

Then, this weekend, we're moving, which sounds relaxing. We're having a "no-furniture" party on the 29th, then I'll be living in CP again.

Ponies

So on my way to work this morning I hear a rhythmic fapping sound. It's tempo is directly correlated to my cars speed. I have a flat tire.

I pull over, get out, and it's my rear-right tire. Ok, I can do this... go to the trunk. Shit, it's a mess, and the board covering my spare and the tools is covered in stuff I should throw away, and the board is stuck to boot. I should clean out my car. Anyway, I pry the board out and get the tools. After taking off the wheel cover, I loosen the nuts. It's much easier to get the nuts off than I expected it to be; last time I had to jump on the wrench to get some of the nuts to come loose, but this time it's like some bad analogy involving hoola hoops and traffic cones... I haven't lost you, have I? I jack up the car, and pull off the tire. Well, that was the plan at least. The tire doesn't budge. All the nuts are off, but it feels like someone welded my wheel to the hub. I put all my weight into it, and still nada. I pick up the phone and call AAA.

After maybe 20 minutes the guy shows up, on the opposite side of the building I'm next to, and I direct him over. He gets there, can't do anything about the stuck wheel, so he gets this green slime in a bucket and pumps some of it into my tire. This is supposed to seal the hole. He then pumps up the tire and it keeps its pressure. Hoo-ahh. Since this is only a temporary fix, I have to take it to a service station and get it done right, so I drive up Rt. 1 to the nearest station, where the mechanic is out. I'm told he'll be back in a half hour, so I figure screw it, I'll just go to the next one up the road. There, the mechanic is there but won't get to it for a while. I'm asked if I can leave the car there. I don't want to deal with any of that... I just want my car fixed... so I drive back to the 1st station and wait.

There's a guy there trying to get his car inspected, and we chat a little waiting for the mechanic. Some other guy (not the mechanic?) starts inspecting this guys car, and I sit... and wait... it's almost noon now. Eventually the mechanic is there and tells me to pull my car up. I drive it over to where he told me and he comes to take a look. First, he notices that my front-left tire is wearing out badly (the inner-tread is gone) so my alignment is probably off. After taking off the nuts from my back tire, and whacking the thing with a sledge hammer (I wonder if that's also bad for my alignment?), the tire falls off. The spare gets put on, and I get to work. I'm going to keep a sledge hammer in my trunk from now on in case this happens again. That, and road-side street-fighting (road-side-fighting doesn't sound as cool.)

I'm taking my car to the Amoco station in Colesville tonight. I think it's a BP now, but I'm still going to call it the Colesville Amoco. I need a couple new tires, my alignment checked, and a general tune up. I also think some belt in my car is wearing out and should be replaced because whenever I drive the car I remember being told by a mechanic some time ago that a belt will need to be replaced soon. What? Did you think I could actually tell that kind of thing based on how the car drives? Hell, I still think there're little ponies under the hood. I'm guessing the belts are there to keep the ponies pants on. Why ponies have to wear pants while powering an automobile, I'll never know: I don't know much about cars anyway.

New Place

On Saturday I got the keys to the apartment I'm going to be living in. It's on the 7th floor, has a balcony, and I believe I was told that I may paint it. I haven't moved into it yet since we still have a couple weeks left at the place in Laurel, but I took a shower there this morning after going to the gym with Jeremy. I'm going to have to invest a lot of money (thank gov for tax returns) into kitchen appliances (microwave, blender, some cooking instruments), a television (maybe), a coffee table, and probably other odds and ends.

We're having a moving-out party on the 29th of April (about 2 weeks from now.) The house in Laurel will be empty other than the drinks, probably something to eat, and something to play music. Oh, and people; there will be people.

BBQ

I know, I know, this is late notice, but we're having a BBQ tomorrow (Saturday) at around 6pm. You should get your arse over here. Also going on that day: I'm getting the keys to my new appartment, and I may go Tuxedo shopping with Tim.

On a semi related note (related in that I'm thinking of it, and I was thinking of that earlier stuff earlier,) google has a calendar application now; www.google.com/calendar. I like it.

Bush bad, Feingold smash!

Saw this on Katie's blog, passing it on. Not much to say about this, just looking forward to quantum cryptography, when it might be possible to communicate and know that it's physically impossible to intercept the message.

Creative writing

I'm going to get started fairly soon on a website idea I've had for a while now, and would appreciate any input from anybody who would be interested in using it. The purpose of the website will be to allow people to compose, share, and critique works of fiction. The writing will be done one page at a time (this is all electronic, so there will probably just be a word or letter limit), but you will be free to use as many pages as you like. I know, this idea is groundbreaking... I'm getting there.

It will be possible to take a partial story (say, pages 1-3 of a 5 page story) and pick up on page 4, following whatever plot line you like. The original story doesn't need to be yours, and anybody can pick up on any page of your new plot line and proceed as they like. The original 5-page story will remain, but at the bottom of page 3, rather than a single link like "go to next page" there will be the option to go to any of the tangential plot lines. You may think of this as just a web-based choose-your-own-adventure authoring tool, but that's not entirely accurate. For starters, there won't be options like "Does Jim open the box? Click here for yes, click here for no." Since this site is meant partially to provide feedback to the authors, pages will be critiqued with both written comments from other authors (assuming people actually do this) as well as numeric scores in a variety of fields (like plot consistency, writing style, etc.) and the links at the bottom of any page will have this information. All the critiques and scores will be provided by the community of writers using the page and the readers. Think of it as peer review. So, to use the above example, someone reading the story, upon finishing page 3, will be given two links, one for page 4a (the first written), and another for page 4b (the new plot line). The links will have the numeric scores displayed, to facilitate the decision of which page to move on to.

Did any of this make sense? If I wrote this would anybody be interested in using it? Any ideas that you think would make it better? Please comment; I'm going to try to get started early next week.

I'm not sure what to do with this.

I wonder if this means that I can be more productive at work without actually showing up, or if I can get into better shape without actually working out. Or if I can tell you about this without actually writing this post. Maybe this post was written without me actually doing it... I'm going to go look at my lunch and think about it.

Intersection!

We're having a party, I guess you could call it, to watch the Maryland vs. Duke game on February 11th. The game's at 1:00 so this won't be a late thing. If you're reading this (no text-to-speech fans welcome) and will be a reasonable distance from our place that weekend, I would highly recommend coming. I can't promise to try to keep my misspoken play-by-plays to a tolerable minimum, but I'll try to try.

Illness

So it seems like I am sick. Actually, it's seemed that way for over a week now. I think I'm getting to the end of it, but it's hard to tell. This started last Saturday after I got my ass handed to me by a black belt. And by ass I mean nose. And by handed to me I mean kicked hard enough to make it bleed. That afternoon I started out with a slight stuffy nose that could have just been blood. That night there was a party at Craigs and I drank, not a lot, but perhaps more than I should have if I was sick. That lasted 4 or 5 days, then progressed into a sore throat with the occasional sinus congestion. I was actually happy with that; cough drops solved most of that problem. Today I woke up and felt much better. I went to Tae Kwon Do tonight for the first time in over a week and my stomach/intestines started hurting. My theory is that it's from the dinner I made earlier: both the bread and the cheese were suspect, but I was hungry. If that's the case than I'm pretty much finished being sick. If it's not food poisoning then I have some bizarre disease that migrates from one symptomatic collection to another. If that's the case, I'm going to bet that it will progress to a horrible flesh eating skin rash. That'll be a fun way to go.

Math question

I'm having some trouble with this math problem Leonard and I are working on. Does anybody know how to derrive the cardinality of an n dimensional real space where n is the infinity representing the cardinality of the real numbers? When n is one, the cardinality of the real space is the same as the real numbers for the trivial reason of them being the same. When n is 2 the cardinality of the 2-dimensional real space is still the same as that of the real numbers (I don't feel like doing a full derivation here but I think I've got that much down sofar). The same holds when n is any natural number, and also when n is the infinity representing the cardinality of natural numbers. But what about when n is the cardinality of the reals?

Or, you could do something at the opposite end of the 'smart' scale...
and see what our friends across the pond have been up to. Related, I saw this a while ago and found it somewhat ammusing, somewhat a batshit stupid waste of my time.
