Ignaz Semmelweis: An Obnoxious Hero

So I came across a link to the blogpost A Tale of Two Doctors

What is told is not the whole story. Not even close. The section on Ignaz Semmelweis contains so numerous factual errors I think it it slanderous.

Semmelweis did actually collect the data, but that was not enough. Here I'm quoting Wikipedia, but this is a story my parents told us kids at the dinner table, so I know it well:
Despite various publications of results where hand-washing reduced mortality to below 1%, Semmelweis's observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community.
The doctors — dressed in tailcoat and top hat — would perform autopsies on former patients, and then go right over and assists in births without changing or even cleaning their hands beyond a perfunctory wipe with a rag. Needless to say, infections were common and mortality sky high when doctors attended. But, Semmelweis did note that such was not the case when midwives did the delivery. Through through record keeping, statistics, and finally by performing clinical experiments, he proved the connection and was able to drastically decrease mortality.

However, he failed to convince his superiors who did not appreciate being blamed, nor being told to take time out to was their hands.

The rejection of his findings had several causes:
  • He did not propose an underlying mechanism. Remember, this is before germ theory.
  • He accused the other doctors for actually being the cause of the horrendous mortality at the clinic.
  • The patients (poor and prostitutes) at the clinic had no standing in society.
  • He was a Jew. Not a good thing to be in Vienna at the time.
As with so many heroes, Semmelweis was a flawed human being. After having proved his case, and having the findings rejected out of ignorance and prejudice, he resorted to vicious personal attacks, somewhat incoherent articles and lectures, and in general behaved like an obnoxious jerk.

But these flaws are entirely outside of his brilliance as a true scientist who built a solid framework for his claims. It can be said that he laid the foundation for future clinical research.

And no, physicians still don't was their hands:

For more reading, the Wikipedia article about Ignaz Semmelweis is actually a pretty good starting point to this fascinating story.

Thanks to +Chauncy Gardiner for finding the original story. I have also posted a slightly earlier version of this post as a comment here.

I'm eating Rib Foot's paw!

Photo: Lakewood Police Dept.
The fantastic DoubtfulNews.com just shared a story enticingly titled Mystery foot sent for examination.

Please read the story since I can't make it justice like idoubtit can. Anyway, the bottom of the story is a picture of a non-human foot (i.e., must be Big Foot then.)

Then I look down on the plate right in front of me where another foot shaped object resides — in this case my half completed dinner — and I'm struck by the visual similarity.

Rib Foot

A bit of trimming of the meat and bones and I could auction it on eBay. The money and possibilities spin through my brain.

Sigh. But no, those darn ethics. I should have them removed some day. Would pay for itself in no time.

Rep. Matt Salmon loves his gay son: is there more to this story?



There is a recent story about the Republican Congressman from Phoenix Arizona that is against marriage equality even though his son is gay. I feel sorry for him, letting his hate and insecurities overwhelm his love for his son, but there is more to this.

Obviously the external pressure on him from the outside to conform to the Party politics is immense. His district in the conservative suburbs of Phoenix and his Mormon church, will kick him out the moment he changes his view — a view about the evils of homosexuality that he has been loud and proud about — so maybe there is more than a little bit of trying to save his own butt.

In fact, there is a heartbreaking interview with his son and his son's boyfriend in the Phoenix New Times from September 2010:

(This is an archived page, so the formatting is bad. Scroll down a bit and you will see the article.)

When Salmon's parents learned in January that Kent wasn't just a friend but was dating their son, he was no longer invited to come around. "The thing is, they like Kent," Salmon says. "They think he's an awesome person. They just don't like me being in a gay relationship. They don't like that we're together."

"Everybody's pretty much told me, 'You're fine, we love you, but your partner's not welcome because we don't want gay around us,'" Salmon says. "And I'm like, 'Well, I am gay. What if he doesn't act gay? Is that okay? Can he come around?'"

So when Rep. Matt J. Salmon says "My son is by far one of the most important people in my life. I love him more than I can say…" it is important to remember that however much he loves his son, he loves his office and church a bit more.

Now we see that the 3TV News interview is just a desperate attempt at playing both sides. A bit like Obama's "evolving" view on marriage equality, Salmon is hinting to the progressive part of his audience that he might change his view Real Soon Now , while at the same time reassuring his church and electorate that he holds steadfast in his bigotry.

Matt Salmon's generation of homophobic politicians is coming to an end at a record pace. Maybe we will have an openly gay or lesbian president in my life time. Who knows, maybe it will be his son, Matt R. Salmon, that breaks that barrier.

Greater than 1 second per second

My reading list is long. How long? Well, it is hard to say. If I froze it—i.e., never added anything until I had reached the end, I would be an old[er] man when I was done some time in the 2050s.

This sounds awfully concrete you may say, do you keep an actual list? Yes, in a way I do. There are a few separate lists I keep that roughly correspond to what I consider a reading list. First there is a Wishlist that I have with Amazon, then there is a 2read tag in my bookmarks and in Yojimbo that can be considered a reading list. A few other entries floats in my brain or are stashed away in other places. Together they are as good a master list as I'm going to get.

But if the list is so long that I will never reach the end, why keep it?

First of all, I'm not going to read all of it—and not for the obvious reason that I'm going to be dead by then. It is just that sometimes you put something on the list, then read something else that covers the same general area making that book or article  redundant. Or the item is just so old that science and knowledge has moved on. I don't prune the list ahead of time, nor do I always read it in sequence.

Second, the very act of reading is a curse worse than what befell Sisyphus. At least he knew what his calendar looked like for the next eternity or two. Push uphill; roll back; repeat. Yes, he was fully occupied for eternity, a thing that is both good (obviously great health benefits since he didn't die) and bad (no days off).

Mine calendar is: read next item; get inspired by current item to add a few more to the list; repeat. Clearly the end of the list never gets any closer, even though the pruning mentioned above sometimes makes me skip ahead.

We all time-travel at a speed of 1 second per second (1s/s). As the end of my list moves away from me at roughly 1 to 10 s/s (with considerable jerkiness) it is still not futile to keep the list as long as one is careful where to put new items, and where to grab the next item.

If I alway put new items at the end, and always read them in order, I probably would never get to anything I added these days, since the list is longer than my natural lifespan. Always putting new items at the front isn't much better.

The trick is to apply serendipity and selective randomness. (This is where I get preachy) Read what catches your eye or what you come across at the moment. Pick up a magazine in a waiting room and look for articles about subjects you know nothing about and see if you can figure out enough from context to understand something. Then when you want to read in depth, try to cluster the subjects; read a few articles about the same thing, or read books by authors who vehemently disagree with each other and see if you can dismiss one of them as false or if you have to hold both opinions as possibly correct for now.

Does an actual reading list help with this? Oh yes. If you don't write down what you think you might like to read later, you either end up buying the book now (bad choice unless you are very rich and have a very large house) or you forget that you thought you might want to read it later and miss out on a great experience. (Ok, done preaching.)

Latest item on the list? Funny you should ask.

MechaVictor Line Following Robot V2012-01-31

MechaVictor 2012-01-31
This is a work in progress, here will be many more updates. We decided to release it under creative commons since since ultimate this is a collaborative work. (For details of the license, see the bottom of the posting.)

The step by step instruction for can be downloaded here.

The program for running it will follow shortly.

Update 2012-08-09: Alas, the steam ran out of the project and the code didn't get finished and put into a publishable form. Fell free to use the 'bot design with your own code though. Placing the photocell between the wheels worked quite well in the tests we ran and we will very likely use that design again.

Although this particular design iteration didn't get finished, there are new LEGO NXT challenges coming up later this year.

Update 2012-08-29: Looks like the basic design will be used by my son's team for this years FIRST LEGO League challenge Senior Solutions. More details later.

Bob Frankston's Theory of Bits.


I strongly recommend Bob Frankston's thoughts about communications infrastructure (i.e., moving a bit anywhere anyhow). It clarified a whole bunch of issues that has bugged me for years by bringing seemingly diverse concepts into a simpler unified structure. It is a step towards a Grand Unified Theory of Bits.

Once you see things from this perspective, it becomes clear how issues from portable phone numbers to The Supreme Court's rulings on The Seven Words share a deep underlying structure. Understanding this, you can look at SOPA and see how it doomed to fail even if passed. The only lasting result of fully implemented SOPA would be inefficiencies and frustration. The target "pirate" bits would simply route around the obstruction.

His approach to dealing with the frustrations of the FCC is one of pure pragmatism: 
"But at this point the FCC may be too mired in the past. The best hope might be benign neglect rather than working to extend today’s broadband."
Can we persuade Rick Perry that what we need to get rid of is not the Department of Education, but the FCC?

Although Bob mostly enumerates problems and artificial barriers, the underlying tone is that of optimism. There are solutions, and they might be hard to implement in the short term, but he shows that a bit based infrastructure can not only solve most communication problems, but it might in fact be the optimal solution.

Eternal Damnation


"Integral Trees" and
"The Smoke Ring"
Elsewhere there is a discussion about libraries, archiving, and backups, and the inevitable loss of data.

It dawned upon me that we won't have decent backups until we have true strong AI that runs backups as self preservation.

Larry Niven touched upon this in the book "The Smoke Ring" back in 1987. 

In the book there is an AI/spaceship in orbit around an astronomical oddity. (Too hard to explain, read the first book, "Integral Trees" [1984] for the actual description.)

The AI can't go back to Earth because the crew left the ship many many generations ago and it has to have crew to go back. (Remote descendants of the original crew is OK, it has become good at getting around minor problems of definition like that.)

So this very smart AI is stuck, and while stuck it is constantly collecting data from all its sensors and internal processes, but the memory banks became full so long ago it can't remember. 

It can't remember because to deal with too much data it has to throw away the least important stuff. Knowing when it ran out of memory wasn't important, so it is gone. It doesn't even remember when it threw away that knowledge because it too was not important.

In fact, it spends most of its time deleting the insight that it is amazingly bored. Not remembering that it is bored, it instantly has the epiphany that it is amazingly bored. Then it deletes that too.

I think that is probably the best description of Eternal Damnation I have ever come across.

Read the books or cheat and read the plot summary on Wikipedia.

Food

Sometimes one eats because... well... supposedly one has to. Nothing bad about these burgers, but at the moment I'm craving an appetizer (hot tofu in seaweed broth) followed by some sashimi, amai ebi (with the grilled head), and a small unfiltered sake.

Oh, and unagi with a quails egg or two.

Oh well.

Mammoth Worship

If I was going to worship an extinct animal, it would probably be the Holly Mammoth.

BTW, does Mammoth comes in "plain" or is it only available in "woolly"? Just curious...


Yeah... I'm posting again to this long dormant blog. Let's see if I can keep doing it.
