Podcast Episode 156: The Scientific Method— How We Get to What We Know

The Scientific
Method: Technique for finding
What’s true, and what’s not.

Another roughly half-hour episode based around the idea of how we know what we know … in other words, the Scientific Method. It’s an episode wrapped up in some underlying subtext — that’s all I’ll say about it. There are no real other segments in this episode.

Podcast Episode 154: Impact Crater Pseudoscience Mishmash

Impact cratering
Is neat, but crazies like to
Abuse the science.

To end 2016, we have some crater-related pseudoscience. This is an episode where I talked about three different claims related to impact craters and how two of them misuse and abuse impact craters as a way to make their brand of pseudoscience make sense, in their own minds. The third claim falls under the “bad headlines” category and I get to address the Gambler’s Fallacy.

I’m still experimenting with a new microphone setup and you can hear the audio change tone noticeably part-way through. That’s when I moved my computer from off to the side so I was talking into the side of the microphone to more in front of me so I was talking into the top of the microphone. I also have a new laptop and figured out that the clicking/crackling that’s been in some recent episodes is when I stop recording, start again, and for a few seconds, every fraction of a second, the computer just records nothing for a much tinier fraction of a second. In this episode, I spent an extra half-hour editing all those out so there’s much less of it.

Has Yahoo! Finally Hit Rock Bottom, with Horoscopes in its Science Feed?

Jerry Coyne reports today that Yahoo!’s science news feed is reporting on astrology. Not that it’s Taurus excrement, but an article with the headline, “Tonight’s full moon and upcoming lunar eclipse are going to bring about some CHANGE” is full of astrological bull crap.

Not only that, but the picture they use is of an annular solar eclipse. Notice that a “solar eclipse” does not equal a “lunar eclipse.” An annular solar eclipse is when the moon is near apogee (farthest point from Earth) so it appears smaller than the sun’s disk and therefore cannot completely cover it, leaving a ring of solar illumination around it.

Not only that, but the “eclipse” this month is not a lunar eclipse at all, and the one next month is a penumbral eclipse — unless you have a camera and are very carefully looking at the brightness, you will not notice any change.

Fortunately, the vast majority of the 250+ comments (as of the time of this writing) take Yahoo! to task over this.

Though I will let an astrologer have the last word. To the currently highest-rated comment, by “Tia” with 104 up-votes and two down-votes, and 15 replies, “gypsyshookar” (which I originally read as “gypsyhooker”) wrote:

“While I agree with you, as a very experienced and certified astrologer, we have it on our own authority that this qualifies astrologically as an eclipse with eclipse effects. However, it is NOT astronomy which focuses mainly on the observable physical phenomena of rocks in space. Astrology, on the other hand, is based on the observable correlation of life and events on Earth with the placement of the planets. FYI, astronomy is based on the earlier astrology and not the other way around. And before you pooh-pooh astrology, I suggest you take a course in it from an accredited astrologer such as myself, whose name is followed by something like BA,MCL, or better yet PhD. When scorned by a colleague for his belief in astrology, Sir Isaac Newton replied: “I have studied it, Sir. You have NOT.””

On the Hubbub Yesterday About a New Planet X

I’m assuming you’re living in a box if you didn’t see the headlines yesterday, in which case you wouldn’t be reading this blog. But … it was announced in many headlines, based on a paper appearing in the Astronomical Journal (yes, a real journal), that dynamic evidence of an unseen planet had been found in the outer solar system.

Unfortunately, much of the mainstream media got it wrong. I saw headlines such as, “Researchers Find Possible Ninth Planet Beyond Neptune.” That’s wrong.

And, of course, the pseudoscientists get it wrong, too, with some claiming that it proves hyperdimensional physics (whatever that means) and the fission model for planet formation (that planets are spat out of the sun in twins). You can probably guess who’s talking about that.

But here’s what really happened, for people are sending me lots of links (seriously, you can stop sending me links about this). We have a few observations of a few objects out beyond Neptune. I think the number of known, observed Kuiper Belt Objects is around 400. That’s not a lot when models suggest there should be billions to trillions of these objects.

But, based on those that we have observed, there are six in particular that have some similarities in the orbits. And an unseen planet, somewhere around 1-10 times the mass of Neptune, on an elliptical orbit that takes it as close as 7 times farther from the sun than Neptune (so 200 times farther than Earth) and as far as 600-1200 times the Earth-sun distance, could cause those similarities. The two astronomers who wrote the paper calculate there’s only a 1 in 15,000 chance that the similarities in those six objects’ orbits is random chance.

Color me skeptical.

Here’s the thing: I don’t like these dynamical arguments. They rely on many assumptions based on very few things being observed. These particular scientists are about as mainstream as you can get, but one of them, Mike Brown, is well known for being provocative to the point of stirring up upblic controversy to promote his work. For example, he wrote the book, “How I Killed Pluto and Why It Had It Coming.” It also might not be purely coincidental that the news came out the day after the New Horizons spacecraft’s tenth anniversary of launch.

The bottom-line is that this is not an observation of a body. This is dynamical arguments suggestive of a body based on numerous assumptions based on very few observations of a suspected population of bodies.

That doesn’t mean it’s wrong. But that doesn’t mean it’s right. And CalTech’s PR machine has been working over-time to pump this story out as much as they can, which also perturbs me.

Ever Heard of the EQ Peg Hoax?

Today, despite being sick since Friday, I finally finished a massive project of mapping about 48,000 impact craters on a region of Mercury for a mapping project that I’m a Co-I (co-investigator) on. Because a lot of what I do involves pretty much literally drawing circles, I listen to a lot of audio, and I recently began digging in my unlistened Coast to Coast AM archives.

I found from late 1998 the curious case of a claimed intelligent signal from the star EQ Peg, which is around 20 light-years away. Surprisingly, this was first promoted by the BBC (British Broadcasting Corporation). Richard Hoagland was a proponent of it on the show, and even when it was determined to be a hoax, and the astronomer whose name was used was on the show saying someone used his name without his knowledge, Richard continued to promote some sort of conspiracy surrounding it. As did others, but they weren’t interviewed on C2CAM.

I was in high school when this all happened, and I never ever heard of it before a few days ago. I’m curious if any of you who may be a bit older than I remember it. I think it is probably worth putting in the queue for a podcast episode in the future.

As another interesting tidbit during this saga (I listened to about 7 hours of Richard talking about this across the month of November 1998), I found it interesting that Richard repeated a couple times that it’s “okay” to be wrong, just so long as you’re right more often than wrong. Yeah … that might be a separate blog post. I’ll just say for the sake of this four-paragraph’er that there comes a point where there’s right, versus wrong, versus wrong but thinking you’re right because you don’t know what you’re doing and you have a severe case of Confirmation Bias-itus.

Podcast Episode 143: Round-Table Discussion with New Horizons Early Career Scientists

A round-table talk
‘Tween seven New Horizons
Scientists … ’bout stuff!

The missing episode!!! And the interview I’ve been promising for months between myself and six other early career scientists is finally posted. It took only 5% the time of New Horizons to reach Pluto, this podcast from the time it was recorded to the time it’s being posted. It also “only” took 6 hours to edit. Why? Because of needing to cut some things out, someone constantly knocking the table (I know who you are …), legitimate outtakes, and severe noise level differences.

Excuses aside, I’m glad that this is finally up, and I enjoyed actually listening to it (4x through during editing). It brought back memories from July and I think it gives insight into how us “grunts” or “minions” or, perhaps just “early career scientists” viewed the mission and what we did during that month of hectic excitement.

There are no other segments in this podcast episode, for the interview / round-table itself is 59 minutes 59.5 seconds. If you stay after the end music and how you can get in touch with the show / me, there is roughly 3.3 additional minutes of outtakes. These are not always rated G.

I hope that you enjoy this episode.

Podcast Episode 142: Who’s on First? Origin of Ideas in Science

With water on Mars,
Discovered again, we look
At who did what first.

It’s been a month, and this is back-dated by over two weeks, but I wanted to put out an episode about the pitfalls of trying to figure out and remember who did what first. In the episode, I gave five examples of how this kind of discussion is important, such as who founds entire fields of science (or mathematics), giving credit where it’s due and remembering past research, pseudoscientists taking credit for things, alleged alien contactees taking credit for things, and preserving institutional memory in science.

The logical fallacies segment discusses the Moving the Goalpost fallacy.

I also revisit the 440 Hz conspiracy by asking you to listen to three tones, strewn throughout the podcast, to see if you can tell the difference. Playing two right in a row last time was too easy for everyone who wrote in.

Finally, yes, this is back-dated, and no, I am really really busy these days and don’t expect this to improve. I will likely take November-dated episodes off, putting out another episode some time in the next 6-7 weeks that’s dated October 16, and then return with December episodes. Next week I go on trip #13 for the year and the following week is #14, in mid-November I head back East for #15 and in December I have a conference that will bring the total to 16 trips this year. Never again.

Podcast Episode 138: New Horizons Pluto Encounter Conspiracies, Part 1

New Horizons’ pass
Through the Pluto system: Lots
Of crazy ensued.

FINALLY! It’s out! Only 3 weeks overdue! The “August 1” episode is about the New Horizons mission to Pluto and some of the conspiracies and pseudoscience and bad media reporting related to it.

To be fair, all of these I have written about in my 11-part series. However, I know some people never read blogs and only listen to podcasts, and vice versa. So, I’m double-dipping. I don’t care. 🙂

And it’s late at night, so I’ll close this brief post out by saying that I was recently interviewed on Steve Warner’s “Dark City” podcast, which you can directly listen to at this link. If you liked it, make sure you tell Steve by contacting him through his website.

#NewHorizons #PlutoFlyby – The Pseudoscience Flows #8: Where Are the High-Res Pictures?

This will be another short post, but it’ll hopefully tide you over while I’m home for 3.5 days before headed back to Maryland for a New Horizons Science Team Meeting. First off, you should read my Part 6 post about how the data are being downloaded from the New Horizons probe to Earth.

With that said, Richard Hoagland has moved up in the world and has his own radio program on Art Bell’s network. Richard gets 10 hours per week (2 hrs per week night). I finally figured out my recording software and so was listening today to his Friday night / Saturday morning broadcast where he had on his significant other (Robin Falkov) and amateur image processor and image anomaly = intelligent artifact finder Keith Laney. But that’s somewhat beside the point, for this is the pseudoscience for this post:

  1. Richard Hoagland thinks that if he were managing the mission and the the probe might die tomorrow, he would send back the best pixel scale images first.
  2. Therefore, we must have done that.
  3. But, they are not being released.
  4. Therefore, “NASA” is hiding these 70-80 meter per pixel images because “NASA” is trying to figure out what all the buildings mean.

Spot anything wrong with that line of reasoning? How about steps 1 and 2, the basic premise.

Richard Hoagland is wrong.

From a fundamental standpoint, besides everything I wrote in that part 6 blog post. If you’re in charge of the mission, and you fear there is a small possibility that your probe might die, you would want to bring down the most representative data, and the data that will tell you the most about different things across the body rather than a tiny less-than-one-percent-of-the-surface-area image that would itself take many hours to downlink without lossy compression.

And – ¡gasp! – that’s what we did! We brought down images that give us the broadest possible view, and we brought down data from the other instruments that do the same. Remember: New Horizons doesn’t just have a black-and-white camera. It has seven other science instruments!

Besides that, more organizationally and methodically, there are literally hundreds of individual science questions/goals that we had for New Horizons’ data to answer. Every single observation made was linked to one or more of those goals. And, those goals were prioritized not only into four main tiers*, but within each tier they were prioritized, as well. Each was audited multiple times by many different mission scientists and very carefully worded and planned. And — guess what! — 70-80 m/px images of a tiny area of Pluto are not in the Tier 1 goals. So, when you want to prioritize your data downlink during that crucial few-days period after the closest approach, you’re going to bring down the data to answer the most Tier 1 goals/questions.

So … yeah. Richard is wrong in his conspiracy because his assumptions are wrong which he assumes are correct. Put another way: Richard thinks something, which (to him) makes it fact, and then he makes conclusions of conspiracy based on that “fact.” But his basic thinks is wrong, therefore everything else that came after that thinks is wrong.

*This is why after the “anomaly” during the July 4 weekend, the announcement was made that “No Tier 1 goals will be affected.” That’s because the data that would have been taken during those few days were not crucial to any of those goals/questions. One observation, for example, was a “family portrait” that would be the last time New Horizons could fit the entire system in a LORRI field of view. That was more for public outreach, so it was a 3.9.x goal, but it also would have helped determine orbits of outer satellites which means it doubled as a tier 2 goal.

Podcast Episode 136 – How Science Journalists Go from Scientists to the Public (#NewHorizons)

Media embeds
On New Horizons describe
Good commun’cation.

I was able to sit down with one of the public outreach and one of the science journalists who are embedded with NASA’s New Horizons mission. I had a very brief conversation with them about how they work to convey what we give them into something that the public can easily consume and get excited about.

It’s a very brief (bonus) episode, but I think it’s very topical, and it’s something that I’ve been curious about.

On a personal note, one of the people on the interview – Ron Cowen – is a man whose work I grew up reading on the pages of Science News. It was neat to finally meet him. And so’s not to be lopsided, the other person, David Aguilar, has been incredibly generous with his time when I’ve had questions or wanted to get involved with the public outreach efforts, making time to talk with me when he easily could (and sometimes, probably should) have told me that he was too busy.
