I was a bit astounded, even in this age of alternate facts and pseudo-science, to hear Kyrie Irving express his belief that the earth is flat. My first reaction was what my Dad used to say when someone said or did something that was ridiculous …. What and idiot! But of course, I know Irving isn’t an idiot or is he dumb. He attended Duke University, for Pete’s sake, even if it was to play basketball. I wondered if he was joking or trying to make a subtle point about fake news, but given a chance to retreat, he stood by his assertion. Several other players, including LeBron James, defended his right to believe that the earth is flat. It is certainly his right but why would he … or his friends … want him to look incredibly uninformed in front of the world, especially when there are so many simple ways to see that the earth is indeed round?

About a week ago, I discovered that our Siamese cat, Mr. P, had fleas. Because our cats are indoor cats, it’s easy forget about fleas. However, they do have access to the roof via my office window. At any rate, if Mr. P has fleas, then Elvis, our Burmese, probably does, too, and there’s a good chance some of the nasty little buggies are in the carpets. I drove to Target and picked up some Hartz flea treatment under the assumption that all flea treatments are created equal. I applied a little bottle of liquid to the back of each feline’s neck and assumed I was done. An hour or so later, I was on Amazon.com buying something and thought I’d see what the flea treatment cost there. To my surprise, the user reviews for the product I’d chosen were all one star, each accompanied by horror stories of sick or dead cats resulting from its use. I admit, I panicked. I drove to the local vet and asked what I should do. She told me that most cats don’t suffer any harmful effects and offered a suggestion of two similar products that they feel is safer (and also kill fleas more effectively). I felt better but still went home and bathed the cats. Did you know, by the way, that soapy water kills fleas if you leave it on for five minutes? A week later, I treated them both with Bayer Advantage II. Fleas, dead and dying, began falling off them almost immediately. End of story. Almost. (more…)
I was talking to somebody a couple of weeks ago about a friend who is struggling with cancer, whose body is so damaged by cancer treatments that it is having trouble healing from a recent surgery. The someone I was talking to, to my surprise, insisted that the cure for cancer already exists but the parmaceutical companies are just hiding them so they can sell other drugs that just treat the symptoms. I was astonished and said so. He told me he could give me the references where I could find the evidence that had convinced him, along with articles about pools of thermite found in the World Trade Center ruins, indicating that our government was somehow complicit in 9-11. He wasn’t happy when I called him a conspiracy theorist and he insisted that he just does more and better research than most people. He was absolutely sure that if I looked at his sources, I’d believe his theories and was insulted when I called them crackpot sources without looking at them. Even though I hadn’t seen his exact sources, I’d seen plenty of similar rubbish in the quagmire of information and misinformation that the internet and social media has created. My someone is not alone.
Yesterday afternoon, I noticed on Facebook that Saturday night’s moon would be a so-called supermoon. Properly called a perigee moon, these occurs when the phase of the moon is full while the moon is near it’s closest position to the earth, or perigee. According to NASA Science, the perigee moon is 14% larger and 30% brighter than your average full moon but without a side-by-side comparison, it is hard to tell the difference. Yes, that’s a scientific, clinical description and it doesn’t prevent people from saying things like, Oh my God, that is the biggest moon I’ve ever seen! particularly if they are observing the moonrise. For reasons not completely understood, the moon looks particularly large as it’s rising from the horizon. This ends the scientific portion of this post. When I read about a supermoon, I am once again that excited kid with his Edmund Scientific reflector telescope rushing out to the hayfield. When the moon rises full, I am the wolf baying, Owooo, owooo at the sky, the young romantic recalling favorite moon songs and favorite moon scenes from the movies. (more…)
Some years ago, we were working on a project to find a very weak sound in a very noisy background using a device known as an adaptive line enhancer. We were using a spectrograph to determine if we’d been successful. The display placed a small bright dot at the location of the signal, which did not stand out before we processed the sounds. If the signal was found, the bright dot would rise above the background. One afternoon, we finally got the thing working and had quite a little celebration. The following day, Kevin, a programmer, told us that when his wife had asked him what he did at work, he told her, We got a little white dot to move about half an inch. Everyone got pretty excited. Of such descriptions, humility is born.
I felt a bit like our friend Kevin last night when I went to see the film, Particle Fever, at the Artsy-Farsty Theater. No, it is not about a disco for physicists … it is the story of the initial tests of the Large Hadron Collider (LHC) near Geneva Switzerland told through the eyes of six brilliant … and quite interesting … physicists. The Collider is the largest and most expensive experiment ever conducted by mankind with a purpose so esoteric that one wonders how the project ever happened. The fact that it was built by a multi-national consortium, including physicists from countries that are mortal enemies makes its completion even more astonishing. By any standard, the scale of the project is mind-boggling – the cost, number of people involved, the twenty-plus years needed to build it and its size. The Collider is built in an underground ring 17 miles in circumference with equipment over five stories high, mostly underground. These are electronics circuits on a grand scale, much of it hand built and soldered. According to Wikipedia, data collected from proton collisions were also anticipated to be produced at an unprecedented rate of tens of petabytes per year, to be analysed by a grid-based computer network infrastructure connecting 140 computing centers in 35 countries(by 2012 the LHC Computing Grid was the world’s largest computing grid, comprising over 170 computing facilities in a worldwide network across 36 countries. The initial goal of the LHC was to verify the existence of the Higgs boson particle, a cornerstone of what is known as The Standard Model. (more…)
I found an interesting article on the Fox News app on my tablet the other day. Now, before anyone launches into a political bias tirade I also peruse headlines on US News and World Report, Real Clear Politics, The New Republic, and The Huffington Post. No, not MSNBC. Every libertarian has his limits. Anyway, the article reported that 122 articles in technical journals, many in publications of the Institute of Electrical and Electronics Engineers (IEEE), were recently found to be computer generated gibberish like, This section provides a complete description of the canceller output spectrum in terms of Discrete Prolate Spheroidal Sequences and their eigenvalues. Just kidding, of course. That is a sentence from my doctoral dissertation. Try this: Application and Research of Smalltalk Harnessing Based on Game-Theoretic Symmetries. Therein lies part the problem … many scientific papers may sound like gibberish to laymen and even to those in a slightly different scientific field. That’s why technical papers are supposed to be peer reviewed by people working in the same field.
Typical seems to me to be an unusual word, one that draws its connotations almost completely from the context in which it is used but that, of course, is a product of its definition: Exhibiting the qualities, traits, or characteristics that identify a kind, class, group, or category. It derives its connotations from the kind, class, group, or category and the particular qualities, traits or characteristics being referred to. If my boss (if I had one) says, You’ve done your typical wonderful job, it’s a complement. If he says, I’m going to have to have Ron look over your report, Bud. That’s typical, it’s not. Well, perhaps typical’s not entirely connotation-free. According to the Urban Dictionary, typical is The word woman use to describe their displeasure and contempt for anything a male could do, would do, will do, or should do in order to please their partner. A woman never explains what is “typical”, it just covers every sin known to man. Hmmm. (more…)
