Planet: Useful in science?
Or, just pedantry?
Sorry for the delay again, but I have an interview that’s just under an hour this time on a new proposal for a geophysical definition of the word “planet.”
In 2006, the International Astronomical Union sparked an uproar and furious debate among scientists and non-scientists alike when they voted for a definition of the word, planet. Numerous proposals since that time have been made for the definition of that term. Eleven years later, a new proposal has gotten a lot of media attention and in this episode, we discuss that new proposed definition. This is closer to a friendly debate style because the guest and I have different points of view on this issue.
There are no additional segments in this episode, but the interview runs 51 minutes. This is also the episode for the first half of March.
To peer beneath the
Photograph and uncover
What may be hidden!
Sorry for the delay, but I have an interview that’s over an hour this time on image processing. In past episodes, I have talked about how you can’t get any more information out of an image than what is in a single pixel. Dr. Tod Lauer is an astronomer who has worked on all kinds of telscopes and instrument data and has developed numerous image processing techniques over his career. In this episode, we discuss some of those and how to correctly – versus incorrectly – apply them to image data to get to the best representation of the original object, or what the image was trying to capture.
There are no additional segments in this episode, but the interview runs nearly 1hr 15min. This is also the episode for the second half of February. I’m very much hoping/trying to get the first half of March’s episode out before I leave on a trip on March 19. It will either be an interview on what’s a planet, or a normal episode on Apollo Hoax miscellaneous claims I never did an episode about.
R136 Star Cluster by the Hubble Space Telescope
Yes, Virginia, there really
Is a Canada.
An episode three months in the making, a cross-over with the crew of The Reality Check (Cheque?) podcast: Astronomy! I had wanted to have the group on this podcast because they had been so generous over the last few years having me on several times, but I couldn’t figure out a good angle. Then, someone (sorry, forget who, but it wasn’t me) suggested we just do a TRC-style show but with astronomy topics. The Reality Check, for those of you who do not know, is a weekly Canadian show that is now just under a half-hour that has four hosts and typically three completely random segments per show. It’s almost nine years old, and it’s kept with that basic format throughout its entire run.
For almost all the segments, I asked them to choose topics from various requests that I’ve gotten over the years. We also did a quiz, in TRC style, that gave me a new appreciation for those on the show who conduct those quizzes every few episode. It clocks in at a little over an hour, which is still short considering that my original audio was nearly 1 hour 50 minutes. Pat Roach, the producer of TRC, did the first cut at merging everyones’ audio and cutting out all the stutters and restarts, so a big thanks to him because I did very little after his first cut.
Totally Not Creepy Podcast Cross-Over Episode
Evidence of real’ty
Changes? No, not quite.
A shorter, bit more light-hearted episode to start off 2017, a look at the “Mandela Effect” phenomenon. This is not a detailed examination of the claims, nor is it a thorough debunking, however. Instead, I briefly describe what’s going on and then give an example of how people have used basic updates to our knowledge about astronomy to make the claim that the entirety of reality has been rewritten but they remember it the way it used to be. (Yes, I wish I were making this up; no, I’m not making this up.)
I think I finally got the bugs in my microphone worked out, or at least a work-around to the bugs, and I think the audio sounds pretty reasonable for once. The episode has three additional segments, including the logical fallacy (argument from popularity), follow-up from episode 146 (Marshall Masters still is predicting Planet X will kill us all later this year), and an announcement that I Was recently on the podcast, “Monster Talk,” discussing Planet X.
Artist Map of the Milky Way Galaxy
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.
Artistic Rendering of Asteroid Impacting Earth
As common in life as ’tis
This is one of those basic science episodes where I tried to provide solid background to a typically misunderstood concept that is beloved by pseudoscientists: Radiation. I go through what radiation is and is not, different kinds of radiation, what it means to say that something is ionizing vs nonionizing, and the effects of thermal radiation. It’s a longer episode, clocking in at 51 minutes.
There are two additional short segments in this episode, the first being logical fallacies where I discussed the nautralistic fallacy, and the second being feedback where I finally addressed Graham’s feedback about the Catholic Church and a round vs flat planet.
“Caution: Radioactive” Sign
Nancy Leider: Still
Claiming Planet X will kill.
But … what’s “Planet Nine”?
Yet another Planet X episode, this time addressing one of the originators of the doom-and-gloom mythos for Planet X, Nancy Leider. I also use Nancy Leider’s latest claims as a springboard to talk about some of the real science announcements, papers, and headlines that have been in 2016 about possible (real) additional planets in our solar system.
There is only one very brief additional segment in this episode, keeping it at just a little over 30 minutes long.
Distant Planet Artistic Rendering
WTF is this
“Dark Matter” stuff, anyway?
Getting away from Earth and going to the biggest scales of the universe, this episode addresses dark matter. I think I can justify it as being on such an important episode (150!!) because I spend the bulk of the episode trying to make the case to you, the listener, that dark matter is real science, in contrast with pseudoscience.
There are two additional segments in this episode: Logical fallacies and two announcements, including an announcement about the release schedule (duh — it’s not exactly on the 1st and 16th of the month).
I also must apologize for the audio – again – on this episode. Only in the editing process did I hear that it sounds horribly muffled/garbled, especially during the first 6 minutes. I’ve had issues with my Blue®™ Yeti® microphone ever since I bought it more than five years ago. I think it might finally be dying, but I’ll try a few things next time and test. Sigh. Thought based on the audio starting around 20 minutes in, which is when I re-started the software, I think it’s possible that I was going in through my laptop’s microphone instead of the Yeti. Again: Sigh.
Conservapedia on the Liberal Pseudoscience of Dark Matter
“Modern Flat Earth Thought”
On maps, flags, and airplane flights …
Does it make sense? No.
Back to the flat Earth, this time discussing map projections and the United Nations flag, and then how some flat Earth proponents use and abuse airplane flight paths to argue that the planet is flat and looks just like the United Nations flag. I want to thank Michael R. (@SkepticalBelg on Twitter) for for reviewing and making several corrections to my text on how the airline industry works.
This was a particularly long episode, nearly a full hour. I also recorded this in a hotel room, and it sounds like I was too close to the microphone and at an angle at times and the room echoed, so my apologies for the audio quality in this episode. It was still better than the audio in the last episode, which was recorded on a phone outside, but it’s not perfect.
There are three additional short segments in this episode, the first being logical fallacies (detailing the argument against antiquity), second being feedback (the correction(s) from Episode 147), and the announcement to thank Michael.
Flat Earth Graphic
X-rays from Pluto change all
We know and hold dear?
First interview episode since The Return, an interview about the discovery of x-rays coming from the vicinity of Pluto. I talk with one of the main authors of the paper announcing the observation of x-rays from Pluto, and we discussed why the find is not severely unexpected, and while it’s interesting it is not something that is completely unexplained. In fact, there’s a very good, natural explanation.
As what was intended to be a 5-10 minute interview ended up running about 50 minutes. Hopefully it was worth it. Note that this was recorded really ad hoc, outside on a university campus, using both an iPod Touch and Samsung Galaxy S5. Interestingly, the iPod performed better relative to noise, but it had a low-end filter; the Samsung had a high-end filter. Therefore, I lined up the audio precisely and combined both so you get better audio, and I tried to lower the relative intensity of each recording if one was picking up the wind more than the other.
There are no additional segments in this episode.
I hope that you enjoy this episode.
