A lot of my thinking on this grows out of the point that the US, and the West in general, is becoming less homogenous all the time. It's not just immigration. With the breakdown of Christianity as the underlying metaphysics of Western society all sorts of other ideologies are coming into play. Secularism is growing but still undefined in many ways. What is the secularist view on marriage? I don't think there is one. Eastern religions are gaining ground, Buddhism doesn't offer any rules on marriage. It just says if you are married you should be good about it. How vague is that?

A second line of thought for me has been, it is necessary for all 50 States in the US to agree? They don't now on all sorts of things. In New Jersey you cannot have self service gas stations. They are common in New York. Marraiges aren't gas stations, but where is the line?

In the broadest scope I've never understood why there has to be laws concerning marriage. It's a private contract. There shouldn't be a question of can two people of the same sex get married - the question should be why we need to regulate this at all. If some regulation is found to be useful, what should it be? I'm not happy about "The State" getting that far into my business.

The lesson for the US in this is one that New York, a very Irish and Catholic City and State, learned. You do this by legislative authority, not juridical. The use of judicial fiat just creates anger and inhibits the building of consensus. It isn't something WE did, it's something THEY forced on us. Ireland agreed with itself on this. The way the US is doing it isn't about agreement, it's about power.

This is why I find myself supporting same sex marriage in NY but hoping the US Supreme Court rules against the suit. In the US this isn't a Federal Case - it is something the States have to deal with. The NSA has given me all the evidence I need to not trust to Federal Authority to solve subtle problems. I can't help but worry that the court case isn't about Justice, it's about finding a shortcut around the slogging of the Legislative process.

There is a lot of controversy on this. As a rule you can't tell from one artifact, it's the number of them and their arrangement that matters most. Key to understanding is the Hollywood version is backwards. Usually in Hollywood you take the a stone and remove stuff till you are left with a tool, like whittling a point on a stick. In reality the bits you take off are the tools. What you have in your hand is a core.

This gives you key pieces to look for, cores being high on the list. Cores are distinctive. The process of making many flakes of a similar size off the core creates a regular and distinct size and shape. They are more rounded at one end, the handle, and then it tapers roughly. There are clear angles and planes to cores. You can tell of the knapper was right handed or left handed. Then you have lots of very regular sized flakes and the core they are off. If you are anal enough - a defining characteristic of archaeologists - you can reassemble the original stone from the cores and flakes. You also have work places for this. It takes some work to make stone tools, so you made a batch at a time. So you have small stone tool work stations. Since they were temporary they were just abandoned as is. An archaeologist can sometimes just sit down and pick up where the original worker had left off.

If you Google "Flint Core" in images you can see pics of many.

We will never know why people do or don't take the courses they do. We will never know why they act as groups the way they do. If we knew why women didn't take engineering courses we would know how to stop genocides.

This article takes as an assumption that getting women to take more engineering courses and becoming engineers is a good thing. There has never been a good answer for why - but there isn't a good reason for why not. The real issue here isn't engineering. It's trusting people and letting them make up their own minds. In this sense we get a conflict between several different ideas of freedom. Rousseau vs Locke. We in America, IMHO, understand freedom to be something individuals exercise, not something we receive or have done for us by any external force. Freedom is limited because people do really bad things sometimes. Baltimore is not just an example of people now making bad, evil, choices. But an example of a history of evil or bad choices. Slavery and Jim Crow can't be defended.

So we are left with a pragmatic statement that women in America take these sort of engineering courses. Since this has worked, and if we take it that getting more women to go into engineering to be a good thing, we should continue to do this.

I'm good with this. The people who want to do this have the same freedom to do it as other have to ignore it. I can't see anything bad coming out of this.

As a father with a daughter studying to be an English teacher this concerns me a lot. There are really two arguments here that are intertwined. One is what is the best way to teach children, the other is what is the best way for teachers to keep their jobs. The expectation is that you get the later by achieving the former. The linkage between these is the argument, but unless it is made specific I don't think this discussion can progress. Right now it is not specific. I want the best way to teach my kids. The teachers job is his/her own problem.

TOA didn't make clear what the author thought, just that he was very worried about his job. I think he shouldn't have been so concerned. The great online colleges are failing faster and faster. The University of Phoenix just reported that it has lost half of its students.They also report that students learn less and remember less. I've tried a number of these going back to a programming school offered by Metrowerks when they still made Mac Programming environments. They never worked for me.

Another issue not discussed is what about disabilities? Any variation from the norm may be disastrous.

Still I think he is right in one way, it will allow for pressure to reduce the pay of teacher and reduce their numbers. We have to remember profit is the difference between the cost and the sale price. If schools with big screen cost half has much, many will call for them even if they only do two thirds as well. And, this won't effect the well off anyway.

The video shows two of these walking up hill, bumping into each other then walking and staying in parallel as they turn and come down hill. The accompanying text points out that this is less complex then a swarm of locusts. This shows we are now building robots that are almost as smart as bugs.

Are these a cause for concern since these are build but for DARPA, and, as anyone who has been stung by a wasp knows, things don't have to be very smart to be dangerous.

raque writes: The NYTimes has published another article on why there is a lack of females in STEM fields.
The article relates a study in Israel where students were given two tests, one scored by their teacher the other blindly. In the one scored by the teachers boys fared better, in the blind one girls fared better. Below is part of my comment on that article:
This article is part of the problem with STEM and STEM education, not part of the solution. It is very hard to develop good experiments and even harder to have news sources report accurately on those experiments. It is well known that it is almost impossible to develop unbiased tests because we have no idea how and why these biases appear or how they operate. African Americans still underscore White Americans on every kind of standard test. This is why places like New Haven CT and NYC have to adjust their scoring of civil service exams to account for that. This same issue of bias in testing is being encountered and widely reported on in India. We also know that that difference in scoring has no reflection on future success. All test are by their nature flawed. Two different tests simply worsens the problem.
If gender is unrelated to ability then in an blind test gender should have disappeared — not be reversed. If it still appears then you have not shown that gender is not an issue in STEM. You have shown that either gender is an issue or that your test is biased somehow — which we knew.

My daughter walked away from STEM after graduating from Brooklyn Tech H.S.. She is going into the humanities. It wasn't bias or the boys, it was the nature of the work. She didn't want to put that much of her creativity into something she didn't want to do. She would rather spend six hours writing fan fic from the point of view of the Impala on Supernatural then spend six hours on working on the animation for a diaper commercial or working on a framework.
Why do we keep assuming females are stupid and need the NYTimes to tell them what they should be doing?

... or principal of nature. It is only a cultural construct that has been occasionally been enforced with limits in some societies in far western Eurasia. It exists to the extent that military power allows and the whims of political powers decide. Socrates only got so far - and as a Citizen of Athens he had more freedom of speech then anyone else at the time. It is a privilege provided by force of arms.

When I was a kid on the streets of Brooklyn - Watch GoodFellas I was in the background of the reality of that piece of fiction - you had to take personal responsibility for what you said and did. If someone didn't like it you could get a flat nose, or be spread over several large black plastic bags in the Fountain Ave Dump.

So to all of those who are busy screaming "FUCK YOU". Would you say that if you had to take personal responsibility for that? That old west "Thems fighting words"? Why yes you say, and after the second beating you'll be far more circumspect.

I was looking to buy my daughter a new laptop for college. We bought an ASUS laptop that had good ratings. It was on woot so it wasn't going to cost a fortune if it went bad. It had troubles right away and had to be sent off for repair. Now it seems to be fine. Apple hardware is still the best. Way not cheap. But ... Windows 8.1 is every inch as good as Mavericks, and better then Yosemite. On a laptop the touchscreen is useful - if only marginally. It is not better then Mountain Lion. Almost all of the new "features" in MacOS are useless and there are more and more bugs. I really don't need my computer to ring when I get a call. On Windows 8.1 for every piece of stupidity there is a really nice feature. Getting the Asus to work on the otherwise all Apple network is maddening. Those bugs are not on the MS side.

I feel stuck. You have to pay close to Apple prices to get good hardware, but the software and just plain strangeness of Apple is making me regret buying so much Apple gear. Getting out of the Apple ecosystem is tough and expensive. One thing that hasn't been mentioned - at least as far as I can see, is Time Machine. It has gottne flaky too. When you try to get to your backups, sometimes they are there, and sometimes that slice is grayed out. You have to mount the backup as a drive to get it to work. Sometimes. Not Thrilled. Now my backups are locked, good luck if I need to get something - which is very likely with a big OS switch.

Getting out of the lock in, even if i keep using some apple products, will be long and hard.

raque writes: I sent my first letter to the editor to the NYTimes on this article/video. I liked it until the very end. Then the author, who is the narrator of the video, says that the hand and the lasso are 'in phase". What!? One of the great problems of science and math writing is the use of words that simply serve to keep out the uninitiated, who now seem to be me. Science is justly determined to be unambiguous in its language. Ergo, "Phase" has one, and only one (or two) meaning. The initiated know what that meaning is, and how that meaning is different from any other meaning (except for the other one). Could someone provide, or point to, a definition of 'in phase" that would be useful here. I did look it up and found ...

The only definitions of "in phase" that Google helps with are the states of matter, and I don't see either the rope or the roper becoming gaseous or liquid (something the roper, I'm sure, is glad of) or if two sine waves have the same peak. I will assume, please correct me if I'm wrong, that two cosine waves having the same peak would be in phase also. But, since cosine is a function of sine ... isn't it? A cosine wave is a sine wave that has been shifted — I think. But the rope is going around ... Since Minute Physics doesn't have a video on this I'm stuck.

The article is different from the video by pointing out that the author of the paper being reported on is the student of another scientist/mathematician who won an Ignoble Prize for why spaghetti breaks when thrown against a wall.

This being Slashdot, I will leave out any other implications of "Whips, chains and ropes". We wouldn't go there.

May I suggest you RTFA.

If you had RTFA you would see that such details are assumed to have been dealt with - or there would be no one to have a space war. You need at least two populations in different parts of "space" for this to happen. Since you count all of the "space" around the and between the population centers in calculating the population density then it is very low per cubic what ever you want to count in.

The first time I came across this math and logic was "Citizen of the Galaxy" by Heinlein. Always recommended. The last really good one was Friday. I never liked it when Lazarus Long would pop up in those last few books.
