False Conflict

I keep finding more reasons why Neil deGrasse Tyson is awesome.

He says several things in this video that I particularly like. At about 3:50 he says that “maybe there is something in the brain’s wiring that prevents some people from becoming atheists.” In a way, I don’t want to believe that because I don’t like to believe that a certain way of thinking (whatever it is) is “pre-wired” but, on the other hand, this explains a lot and, as I (and others) have said before, brains are weird. I also respect him for trying to avoid politicizing science, though that’s often impossible.

I wish I could introduce Neil deGrasse Tyson to my grandmother. Actually I wish I could introduce a lot of people to my grandmother. She was extremely conservative. She thought almost everything on TV was immoral in one way or another. It’s probably not surprising that she objected to I Dream of Jeannie but she even considered The Lawrence Welk Show immoral because when the young ladies on the show danced and whirled around you could see their knees and (gasp!) sometimes even their thighs. From knees to belly buttons to kids smarting off at their parents there was no show so wholesome she couldn’t find something wrong with it. (and we’re talking about the 60′s, when TV couples slept in twin beds) She had similar opinions about real life behavior. You might assume from this that she was an unpleasant person but she wasn’t at all. She was usually cheerful and pleasant and never preachy but when certain subjects came up she would certainly tell you what she thought.

My grandmother read the Bible every day and believed in it and considered it a guide for living but one thing she did not believe was that the world was created in only six days. She understood that the Bible was never meant to be taken literally. I can clearly remember when I was very small she explained to me that both Genesis and evolution were true because the Bible said that to God a thousand years were as one day, which, of course, she also did not take literally. The world was not created in six thousand years any more than it was created in six days.

That one person could believe both the Bible and the true time scale of evolution and that humans evolved from a single cell, up through amphibians, small mammals, primates, early hominids to modern humans, does not compute for some people but I say, “Why not?!” We all believe things that are much more unlikely than that. My grandmother did not care for conflict. She did her best to educate her children, grandchildren, nieces and nephews but was content to leave strangers to believe anything they liked, but I know that if asked she would have said that creationists reduce God to human scale because they are not capable of grasping anything greater.

My grandmother was actually very interested in science. To her, science was the study of God’s creation so you had to get it right. I’m sure there are people who would say that she was cheating, that she had been convinced of the scientific truth of evolution but still couldn’t let go of religion. Perhaps there’s some truth to that. So what? People manage to reconcile seemingly conflicting ideas in their minds all the time, maybe because these ideas are not really as opposite or mutually exclusive to one another as some have been led to believe. Maybe someone with an agenda decided that a conflict would be to their advantage, created one, and convinced a lot of other people. Oh man, I wish I had that kind of talent! The talent to convince people. Well, if I can’t maybe Dr. Tyson can – the kids at least.

Playing Games For Mental Health

Researchers have developed a smartphone app that can reduce anxiety.

The game is based on an emerging cognitive treatment for anxiety called attention-bias modification training (ABMT). Essentially, this treatment involves training patients to ignore a threatening stimulus (such as an angry face) and to focus instead on a non-threatening stimulus (such as a neutral or happy face). This type of training has been shown to reduce anxiety and stress among people suffering from high anxiety.

In the study, about 75 participants — who all scored relatively high on an anxiety survey — were required to follow two characters around on the screen, tracing their paths as quickly and accurately as possible.

After playing the game for either 25 or 45 minutes, the participants were asked to give a short speech to the researchers while being recorded on video — an especially stressful situation for these participants.

The videos revealed that participants who played the ABMT-based version of the game showed less nervous behavior and speech during their talk and reported less negative feelings afterward than those in the placebo group.

That makes sense but I wonder if it has to be their specially developed game or if pretty much any low stress game could have the same effect.

“This can’t happen with a real book”

That was my immediate thought last night when my Kindle, quite strangely, went back to the beginning of the book I’m reading when I exited the dictionary. I was 40% of the way through the book! I didn’t know what to do and it was late so, heartbroken and worried, I decided to deal with it tomorrow (which is now today) and turned it off.

The first thing I did this morning was to search the Kindle forums on Amazon. This error has happened to other people and there is no automatic way to go back to where you were in the book. The best suggestion was to search on a phrase you remember from the page you were reading. Well, of course, early this morning I couldn’t think of any exact words that I had read last night. But slowly, after morning tea, the fog began to lift and I remembered something that got me very close to where I was.

Now that the panic is over, really thinking about it, it was no more of an ordeal (maybe less of one) than finding your place again in a paper and ink book when you drop it and lose your place so, even though that should not have happened, I still love my Kindle. I’m a little bit peeved at it for losing my place and I still wonder how such a thing could happen but no technology is perfect. It’s so easy to get into the habit of trusting it.

In the Next Five Years?

Five Surprising Things That Will Happen in the Next Five Years. I have not watched all five of the videos yet but I must say that I’m skeptical about these things happening in just five years and I do not think I would welcome #’s 2 and 5.

Regarding local retail beating online shopping: I have no doubt that local retailers will improve – they have to – but it will remain impossible for local stores, especially small town stores, to keep in stock everything that anyone might want. And there are some kinds of stores (book store, fabric store) that do not even exist in the small town where we do most of our local shopping. (nor in any of the surrounding small towns)

Of all the five things, #3, “doctors will routinely use DNA to keep you well,” is the one I would most welcome but I’m extremely skeptical that it will be routine within five years and it certainly will not be affordable and since insurance companies are extremely reluctant to cover anything new, their definition of “new” being anything approved in the past 30 years, this will affect very, very few people.

I am seriously tempted to put this post in the Sci-Fi & Fantasy category.

Weather Terms

I am not a fan of The Weather Channel. It’s okay. As cable/satellite channels go it’s relatively inoffensive but it’s just not that useful or interesting to me. I do sort of like Coast Guard Alaska but I rarely watch even that. So I was just a little bit surprised to find that their website is somewhat more interesting than their TV channel. I found their extensive Weather Glossary when searching for something else. That could definitely be useful. I love glossaries.

Today Is For the Birds

I took these photos a little while ago through the small window in our front door, with the camera at near maximum zoom.

The feeder on the left contains sunflower seeds, the one on the right contains thistle seeds, with the suet cake holder in the middle. This feeding arrangement brings us a wide variety of birds year round. We don’t always provide suet cakes in the summer. The greedy little things can gobble one down in only a day or two. Depending on the season, we get cardinals, downy woodpeckers and occasionally red-bellied woodpeckers, sparrows, chickadees, tufted titmice, blue jays, and several different species of finches including goldfinches and purple finches. (which are not really purple at all) I have seen blue birds but only rarely and last summer, for the first time ever, I saw indigo buntings. (That’s our neighbor’s truck and front door in the background.)

I Will Wear Purple…

There’s an interesting “by the way” in one of Erin’s Hundred Dresses posts.

I’m not a fan of purple, not really sure why. I understand it’s a color that grows on you when you’re older; I saw some research somewhere about how your eyes perceive different wavelengths or perceive the same wavelengths differently or something (could I be more vague? no, I could not) and it somehow explained the tendency of older women to wear more orangey lipsticks. Which I thought was probably complete and utter BS, but that factoid has stayed with me and here we are, no better off than we were before, but prepared for the possibility, however remote, of someday feeling more kindly towards purple.

Of course that sent me googling but I wasn’t able to come up with anything except for several articles saying elderly people lose some of their ability to see colors. I’m not sure I believe that or maybe I just don’t want to believe it but I have never noticed anything to suggest that in the older people I have known.

I did come across a couple of interesting color related things though. This one about Ancient Greek Color Vision seems bizarre.

And… Don’t take this test if you are confident in your ability to distinguish different colors. I didn’t do really bad but not nearly as good as I expected. I might try it again later.

My “favorite colors” change from time to time but overall I don’t really have a “favorite” color. I used to think blue was boring but I like it much better now. I like purple but it’s never been one of my top favorites. I’m attracted to pink, yellow, orange, and red. But I also like brown.


Brains are interesting. Fascinating, in fact. Sometimes I think I should have been either a neuroscientist or a psychiatrist but, with the former I might have to dissect actual brains and with the latter I would have to deal with annoying, messed up people all the time, which is not one of my talents. (You see why I never decided what I want to be when I grow up?)

Anyway, like I was saying, brains are fascinating. We’ve been watching the series (on the History Channel) Your Bleeped Up Brain. It’s very similar to another series, Brain Games, but it’s better, I think. They seem to try a little more to explain the science instead of just, “Watch this; see how we can trick you!” So far nothing in the series has surprised me. It’s all stuff I knew already but it is still interesting to me. Last night we watched the episode about superstition. They seemed to be trying to avoid offending anyone. It was more about our brains finding explanations for things we don’t understand and why we cling to those explanations even when they are proved to be wrong.

They showed a bit about seeing faces in random patterns. Like everyone else, I do see faces everywhere but I don’t ever see it as a sign of any kind. To me it’s just another way for me to entertain myself. It’s a kind of optical illusion. I do sometimes fantasize about finding a picture of Jesus on a rock or in the grain of a piece of wood or something and selling it for a fortune on eBay.

The thing I think we all have a hard time with is accepting that other people’s brains are in some ways different from our own. For example, my brain likes words and it likes for them to be correct. (“Correct” meaning, the way I first learned them, whether they are actually correct or not. “Kilometer” is one that I think the majority of us in the U.S. learned to pronounce incorrectly. I know how it’s supposed to be pronounced but to me right sounds wrong and always will.) I understand – and on one level I accept – that not everyone’s brain likes words the way mine does and that this is not a sign of intelligence or lack thereof, but still, my brain wants what it wants and it very much wants everyone to stop typing “there” when you mean “their” or “they’re,” and other common mistakes.

My brain also has a bit of a problem with hints and I sort of think this might be part of the liking words thing. Whenever someone is hinting or trying to convey something to me non-verbally, even if I do get what they are trying to tell me, my brain keeps urging me to shout, “Just say it already!” I really try not to do that because I know I’m the weird one in this case but again, my brain wants what it wants so I have a bit of difficulty responding to hints. Strangely, that doesn’t mean that I don’t use hints myself sometimes. Yeah, my brain is bleeped up too.

What other people’s brains want I don’t entirely understand. I am an intelligent and tolerant person (At least, I understand that tolerance is a virtue and I should be more tolerant.) but I have a hard time understanding what drives other people, especially obviously intelligent people. Idiots (and there are a lot of those in the world) can be easily dismissed but when I run into an obviously intelligent person whose understanding of the world is completely different from mine (such as people who voted for “the other guy”) a part of my brain automatically wants to label that person “idiot” also, even though I know better. This seems to be one of those things, like seeing faces, that all of our brains have in common. And when the other person is someone we know and like our poor brains may not know how to handle the situation.

I guess most people don’t think about this stuff. Maybe if more people were educated about the way our brains work the world would be a more peaceful and tolerant place? Or maybe not. We all believe what we want to believe – that we are right and they are wrong – so even if we understand how our brains work we will each continue to think that our own brain is somehow better than all the other brains even if some of those other brains can do calculus and ours can’t.

The Hole in the Sun

By now you’ve probably all heard that there’s a gigantic hole in the sun. Actually it’s just a coronal hole, an area that is “darker, lower-density, and (relatively) colder than the rest of the plasma on the surface” of the sun. But of course the news sites couldn’t pass up such a perfect opportunity for scare headlines, could they?

Well, I am capable of recognizing opportunity myself so let’s have some fun with this and see if we can make the ol’ hit counter go up a bit.

* The Hole in the Sun was caused by secret government weather control experiments.

* The Hole in the Sun was caused by nuclear testing on Earth.

* The Hole in the Sun was caused by too many satellites orbiting the Earth.

* The Hole in the Sun was caused by a probe that NASA launched into the Sun.

* The Hole in the Sun is a punishment from God for allowing gay people to live.

* The Hole in the Sun was caused by Republicans.

* The Hole in the Sun was caused by Democrats.

* The Hole in the sun was caused by the North Koreans.

* The Hole in the Sun was caused by aliens from an ice planet who are planning to cool off the Earth so they can inhabit it.

* The Hole in the Sun was caused by friendly aliens who have come to help us with our global warming problem.

* The Hole in the Sun was caused by obese people sucking all the heat out of the sun.

* The Hole in the Sun was caused by the death of algae in the oceans.

* The Hole in the Sun was caused by antibiotic resistant bacteria due to the excessive use of anti-bacterial hand cleaners.

* The Hole in the Sun was caused by zombies.

* The Hole in the Sun was caused by vampires. (Well, it makes sense… vampires like the dark.)

* The Hole in the Sun was caused by cell phones.

Okay, your turn. What “really” caused the “hole” in the sun?

Picturing Pre-History

Science has pretty well established that we are all part Neanderthal as well as part African, which I’m sure is highly disturbing to some people. There’s nothing in this article that is very new or surprising. What’s interesting and kinda funny is the picture accompanying the article. It shows a blonde, modern European woman and a dark, brutish pre-human male nose to nose looking adoringly into each other’s eyes. Mouseover the image and read the annotations, especially #’s 3 and 5.

History has never been as pretty as we would like it to be.

Changing Etiquette

Do digital devices change the rules of etiquette? In some ways, I think so. I can sort of understand the example of the thank you email but I’m not sure I entirely agree. I can understand that if you get a lot of email one more “unnecessary” email could be considered a burden but, personally, I like getting a response of some kind. If I send someone an email I want confirmation that the person read it.

When texting I often use complete sentences and always correct spelling. (Well, at least I intend to use correct spelling.) Are long texts rude? Well, if you’re not going to reply to my emails what the hell do you expect!? That’s the way I feel about it. If you don’t want people to keep bugging you then communicate with them.

One change that I do like is that sending a text is considered more polite than calling. I totally understand and agree with that. A text can be ignored for a few minutes if you’re too busy to respond but a phone call traps you. Not that phone calls are not okay. The old-fashioned telephone call is appropriate sometimes.

Not that I have all that many people with whom I communicate. Just family, and digital communication works great for us. We all seem to be in sync as far as knowing what’s expected.

Food Fraud

There’s a good chance that some of what is served as calamari is actually pork bung. Well, I think I’m safe; I wouldn’t knowingly eat either one. But, sadly, that’s not all.

Samples sold as snapper and tuna had the highest mislabeling rates (87 and 59 percent, respectively), with the majority of the samples identified by DNA analysis as something other than what was found on the label. Only seven of the 120 samples of red snapper purchased nationwide were actually red snapper. The other 113 samples were another fish. Halibut, grouper, cod and Chilean sea bass were also mislabeled between 19 and 38 percent of the time, while salmon was mislabeled 7 percent of the time.


“Our study identified strong national trends in seafood mislabeling levels among retail types, with sushi venues ranking the highest (74 percent), followed by restaurants (38 percent) and then grocery stores (18 percent). These same trends among retail outlets were generally observed at the regional level,” Oceana said in their summary report.

And it’s not just seafood that might not be what it seems:

But what about honey? Or extra virgin olive oil?

These are products most of us believe we could spot as fraud. However, most of the honey sold in American chain stores does not meet international quality standards.

Testing done for Food Safety News found that most store honey isn’t honey, with ultra-filtering techniques removing pollen and hiding the honey’s origins.

“More than three-fourths of the honey sold in U.S. grocery stores isn’t exactly what the bees produce.

I knew about most honey being excessively processed, if not outright fake. I try to always buy honey produced in Oklahoma. There’s not a huge difference in taste and I can’t tell if it’s less processed than other honey available in the grocery store. We have a beehive in our back yard but haven’t been very successful at beekeeping. We got honey from them only one year.

Dogs and Cats

This is what I always say, but she said it better:

Here’s a question that could get us in trouble. Are dogs smarter than cats?

It’s a very difficult question to answer in any meaningful way. I could ask you, which is a better tool, a hammer or a screwdriver? They’re designed to do different things. Compare the origins of these animals in the wild, their progenitors, the wolf and the wild African cat. You have one that is an endurance runner, a pack animal that relies on cooperation. You have another that is a relatively asocial, stalking hunter that relies on stealth to be successful. These are completely different social systems and ways of life, and evolution shaped those minds to be really different because they do completely different things in terms of how they make a living.

From this interesting article about dog intelligence.

There’s one thing mentioned about dogs that I’ve noticed in my cats: deceptiveness: “dogs avoid misbehaving if you are watching them”. My cats are geniuses at that.

Science Videos

I found this interesting series of videos, with simple answers to various science questions. It was hard to pick just one. There are videos about “The Monty Hall Problem”, “Motion Sickness”, and even “Zombie Apocalypse Science”.
