Faster-than-light neutrinos?

I came across this BBC report about some observations at CERN that suggested that neutrinos may be traveling faster than the speed of light. If this is true, it would mean that one of the pillars of modern science, the theory of special relativity, would have to undergo serious scrutiny.

I personally was not too excited by the news and was not even planning to comment on it but it seems to be causing a media sensation and several blog readers sent me clippings from various sources and asked for my opinion, so here it is.

I think that this result is unlikely to hold up and so am not too excited. The reason that I am underwhelmed is that I have been around long enough to recall many previous sightings of tachyons (the technical term for faster-than-light particles) that turned out to be false alarms. They are like Elvis sightings in that there is an initial flurry of excitement that then fades under closer scrutiny. The scientists who reported the recent events are aware of this history and are understandably cautious about making any grandiose claims. They can depend on the media to do that. If other research groups study this is some detail and the results hold up, then there will be cause for excitement. This will likely take a couple of years. Until then, I treat this with considerable skepticism.

So my present attitude is captured in this xkcd cartoon that I saw via Jeff at Have Coffee Will Write.

Sorry to be such a downer but if the history of science teaches us anything it is that the great and enduring theories of physics are never overthrown on the basis of a single experiment.

‘Poor, ignorant atheists’

Recent results revealed by the US Census Bureau show that the ranks of the poor have increased to record levels in the US.

This should really come as no surprise to any thoughtful observer, given the relentless drive by the oligarchy to squeeze everyone else in order to enrich itself. But Walter Russell Mead, one of those so-called ‘centrist’ establishment pundits so beloved in the media who can be relied upon to deliver conventional wisdom on any topic, has come up with his own explanation as to the reasons why. He says that the growing inequality in the US is due to the rise in numbers of poor, ignorant atheists. Why? Because when people leave religion, they also leave religious institutions that promote the virtues that could lead them out of poverty.

Discussion on the scientific basis for justice and altruism

On Friday, September 23, I will be leading a discussion on these ideas, especially the work of Frans de Waal, Paul Bloom, and Peter Singer on the implications of the theory of evolution.

It will take place from 12:30- 2:00 pm in Nord 310B on the CWRU campus.

The event is free and open to all. Drinks will be provided and you are encouraged to bring your own brown bag lunch.

Elizabeth Warren on Morning Joe

I feel sorry for Elizabeth Warren. Now that she is running for the US Senate in Massachusetts, she will have to deal with an endless stream of preening media personalities who delude themselves that they are journalists.

A prime example is Mark Halperin, who asks her what she would do about the military threat from China. My first reaction was, “What the hell? Why are you asking about something that is so far down the list of concerns?” But the smug expression on Halperin’s face answered my question. I recognized immediately the obnoxious student that all teachers have encountered who thinks up a question on an obscure topic because he thinks it will impress his peers if he can stump the teacher. There is, of course, no reason why Warren should have thought deeply about this particular issue since it is clearly not high on her list of priorities and, being a veteran college instructor, she knew exactly how to deal with such smart-alecks.

Similarly another so-called journalist Mike Barnicle framed his question with such a long preamble that one lost interest in it long before he got to the end. What these people want is to get face time on television, not inform and educate the viewer.

Watch Warren answer these questions well enough and with much greater patience than I would have been able to muster.

The scientific basis for justice and altruism-part 4

(An expanded version of a talk given at CWRU’s Share the Vision program, Severance Hall, Friday, August 26, 2011 1:00 pm. This program is to welcome all incoming first year students. My comments centered on the ideas in the common reading book selection Justice: What’s the right thing to do? by Michael Sandel. See part 1, part 2, and part 3.)

In the previous post, I pointed out that experiments with babies suggested that although the theory of evolution supports the idea that the desire for justice and fairness is part of our genetic makeup, it is also limited in that seems to stop with our relatives and immediate community or nation. It is not entirely limited, though. There are many examples in evolution of characteristics that evolved to serve one purpose but then get used for other purposes. Sex is a good example. The pleasure it gives served the purpose of encouraging procreation but now people indulge in it for pleasure alone. Similarly, although the desire for justice my have evolved within the domain of kin and the immediate community to benefit the propagation of genes, it can still drive our relationships with the broader community even when there is no genetic benefit.

We’re #25!

At least as far as internet speeds go, just behind Romania.

If it seems extraordinary to you that the country that pioneered the internet should lag so far behind now, Tim Karr explains that the prime cause is the lack of competition here, thanks to the ability of the telecommunications giants to pressure regulators.

In the years that followed the signing of the 1996 Telecommunications Act, lobbyists working for powerful providers like AT&T, Comcast and Verizon pressured a compliant FCC to tear down all of the important safeguards established by Congress.

While the U.S. blindly followed a path of “deregulation,” other nations in Europe and Asia beefed up their pro-competitive policies. The results are evident in our free fall from the top of almost every global measure of Internet services, availability and speed.

The lack of competition has turned America into a broadband backwater. In the aftermath of the FCC’s decisions, powerful phone and cable companies legislated and lobbied their way to controlling 97 percent of the fixed-line residential broadband market — leaving the vast majority of consumers with two or fewer choices of land-based providers in any given market.
The absence of true consumer choice has driven prices up and services down.

The scientific basis for justice and altruism-part 3

(An expanded version of a talk given at CWRU’s Share the Vision program, Severance Hall, Friday, August 26, 2011 1:00 pm. This program is to welcome all incoming first year students. My comments centered on the ideas in the common reading book selection Justice: What’s the right thing to do? by Michael Sandel. See part 1 and part 2.)

There is considerable evidence that the desire for justice and fairness is innate in us. In an article titled The Moral Life of Babies (New York Times, May 5, 2010) child development psychologist Paul Bloom describes how very young children have a strong sense of justice.

A growing body of evidence, though, suggests that humans do have a rudimentary moral sense from the very start of life. With the help of well-designed experiments, you can see glimmers of moral thought, moral judgment and moral feeling even in the first year of life. Some sense of good and evil seems to be bred in the bone.

He reports on experiments in which babies were presented with puppets who either helped or hindered other puppets.

In the end, we found that 6- and 10-month-old infants overwhelmingly preferred the helpful individual to the hindering individual. This wasn’t a subtle statistical trend; just about all the babies reached for the good guy.

We found that, given a choice, infants prefer a helpful character to a neutral one; and prefer a neutral character to one who hinders. This finding indicates that both inclinations are at work — babies are drawn to the nice guy and repelled by the mean guy. Again, these results were not subtle; babies almost always showed this pattern of response.

Sometimes the babies were quite emphatic about their preferences.

Not long ago, a team of researchers watched a 1-year-old boy take justice into his own hands. The boy had just seen a puppet show in which one puppet played with a ball while interacting with two other puppets. The center puppet would slide the ball to the puppet on the right, who would pass it back. And the center puppet would slide the ball to the puppet on the left . . . who would run away with it. Then the two puppets on the ends were brought down from the stage and set before the toddler. Each was placed next to a pile of treats. At this point, the toddler was asked to take a treat away from one puppet. Like most children in this situation, the boy took it from the pile of the “naughty” one. But this punishment wasn’t enough — he then leaned over and smacked the puppet in the head.

The toddlers also watched pairs of puppets in which one puppet did a good or bad thing and the other puppet rewarded or punished the first. Of the four possible combinations of actions and consequences, toddlers overwhelmingly preferred the puppets that rewarded good acts and punished bad acts over puppets that rewarded bad acts and punished good acts. This showed that the babies were not basing their preferences on what they perceived as good or bad actions but viewed the actions in the context of the purpose they served. This is pretty sophisticated thinking about crime and punishment and justice.

The desire for justice is strong and biological but is limited. For example, toddlers tend to prefer people of their own races, who speak their own language and share their taste in food. Bloom writes that:

3-month-olds prefer the faces of the race that is most familiar to them to those of other races; 11-month-olds prefer individuals who share their own taste in food and expect these individuals to be nicer than those with different tastes; 12-month-olds prefer to learn from someone who speaks their own language over someone who speaks a foreign language. And studies with young children have found that once they are segregated into different groups — even under the most arbitrary of schemes, like wearing different colored T-shirts — they eagerly favor their own groups in their attitudes and their actions.

So are babies and little children racists? If you waggle your finger and go “kitchy-coo” at a baby of a different racial group, will it bite you? It might, but the babies are not making conscious decisions to prefer their own, which is the real mark of racism. They are simply reacting instinctively based on their biology. So biology seems to strongly suggest that our desire for justice, though it is biologically based on our long history of evolution, is also limited to our in-group. This difference in the way we treat in-group members versus the way we view those who are ‘out-group’ members can and does lead to all manner of strife and tribal behavior between communities, religions, castes, and nations.

So does the theory of evolution say that our biological desire for justice stops with our relatives and immediate community or nation? In the next and final post in this series, I will look at how we overcome that kind of parochialism.

Bathroom mania

For reasons that are not clear to me, the Plain Dealer wasted a huge amount of the limited space in its front section to a story about a fancy lakefront property that was on sale for nearly $20 million. The item read like a huge, free, real estate advertisement and fell into the category of what is known as ‘real estate porn’, that showcases the absurdly extravagant homes of the wealthy.

But what struck me was that the 38,000 square foot house built on 160 acres consisted of five bedrooms, nine bathrooms, and seven half bathrooms.

Why would you need sixteen bathrooms for a private home that has just five bedrooms? Do rich people need to go to the bathroom a lot and so must have one handy at any moment?
