About This Club

The name explains it : This club is meant for discussions of any sort of physics, chemistry, biology, geology, astronomy, whatever science you want you comment about. This might be a good place for sharing hypothesis or complete theories as well, so suit yourself and imagine all the crazy things you can imagine, science knows the way! Anyone may join, however the privacy is set on 'closed' to avoid spam, hopefully this will keep that at bay. Upon entering the club, I strongly encourage you to write a short introduction to tell others about what your interests in science are and what experiments you've made happen (if you have), and of course, if you're working on any project/hypothesis that needs discussion, this will be the place too.
  1. What's new in this club
  2. Or at least they think they know it is connected to oscillations in the planet's magnetic field.
  3. Where's Wald.. er.. I mean Ingenuity. (Hint... it's right there next to the rock.)
  4. New details of the ~350yo supernova from the James Webb space telescope... https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_reveals_new_details_in_Cassiopeia_A
  5. This one ought to be good for a few dramatic moments, including the landing and launch from Mars caught on camera by the rover. https://mars.nasa.gov/msr/
  6. This post will contain spoilers for the anime Madoka Magica, the 12 episode anime. I just recently finished watching the anime episodes of Madoka Magica, which gives a take on many philosophical questions, one of them being related to physics and I really thought it was worth exploring. The problem is as follows: In this universe, there's a civilisation of seemingly advanced magical creatures that are described as feeling no emotion (or those that do are considered mentally ill), and they wish to make 'progress'. They have sought means to harvest energy to make up for the rise of entropy for a long time, and their answer was to harvest the emotions of the human race. Their sadness, rage, happiness, their whole souls, basically. They do this by providing each person who makes a contract with them magical powers, turning them into a magical girl. Once they give up their soul, the human is subject to harvest energy from distorsions in reality that corrupt and cause the suffering and death of people. It doesn't sound too bad... does it? Later, it is revealed that the humans are eventually destined to return the good they've done for the world, in the opposite way. Because of giving up their soul, they are prone to losing themselves and becoming the very distorsions they used to destroy, only this time causing all the pain back that they once thought they avoided. The advanced civilisation creatures don't care, for their lack of emotions, and they've been thriving off of humanity's suffering for as long as history knows. My personal belief is that when the question comes up, 'what's the price of an eternal civilisation?', my firm answer is that there is none that are worth the exploitation of other beings. The exploitation of other planets, living creatures. I believe the universe should die at one point. Entropy does its thing, and that will be the end of it. If you were given the choice, would you accept to extend the life of the universe? If so, what's your purpose and reasons?
  7. A new asteroid named "2022WJ1" was detected.. and just a few hours later detonates in the air over Niagra falls. Barely even enough time to say, "oh, shit!" Fortunately it was only a few feet across. The real news here of course is that it was detected before impact. This is only the 6th time we've managed to do that. As usual Scott Manley has some good coverage of it in this week's space summary.
  8. “It is surprising that people do not believe that there is imagination in science. It is a very interesting kind of imagination, unlike that of the artist. The great difficulty is in trying to imagine something that you have never seen, that is consistent in every detail with what has already been seen, and that is different from what has been thought of; furthermore, it must be definite and not a vague proposition. That is indeed difficult.” —Richard Feynman The Quotable Feynman (ed. Princeton University Press, 2015) - ISBN: 9781400874231
  9. "Here we present 4.5 yr, 16-band photometry of Betelgeuse between 2017 and 2021 in the 0.45–13.5 μm wavelength range making use of images taken by the Himawari-8 geostationary meteorological satellite." Cool stuff, at least for a space nerd like myself. (And yes, this is what I do for recreational reading these days. I might need professional help. ) https://www.nature.com/articles/s41550-022-01680-5
  10. https://photojournal.jpl.nasa.gov/catalog/PIA14033 https://www.vice.com/en/article/78kwjd/why-the-first-close-up-image-of-mars-was-hastily-painted-in-pastels
  11. Just a concept at this point but wouldn't that be cool? The mission would even include a probe to drop into the planet's atmosphere. I'd want to see Triton close-up too, though with its orbit it might be difficult to get anything more than a few awkward flybys.
  12. (Been looking at latency numbers for the past couple weeks at work. Nice to see results.)
  13. Interesting theory. Nice tie-in with string theory too. Is ST finally becoming useful?
  14. Impressive explosion no doubt, but quite a lot of interesting science to be done as well. No doubt there will be more info coming out momentarily but as usual Scott Manley does a pretty good job of putting together a summary and initial commentary on the event..
  15. So, any geologists in the room? I'm not but I've been following this volcanic eruption in Iceland and I must say it has me hooked. Some very good stuff being posted on places like Youtube, including 4k video from drone overflights of the vigorously-boiling lava as it overflows the vent and flows out to fill the surrounding caldera. Very photogenic if nothing else. I'm in the habit now of queuing up the latest and just having it running as background while I'm doing other things. There's also cool stuff like this 3d/GIS model/dataset online if you want a more interactive experience.
  16. So now there's at least two experiments that are hinting that there's something odd going on with muons. Still needs more supporting data - and a testable hypothesis about what's going on would be nice as well - but it already seems pretty solid.
  17. What we know now, what we'd like to know, and some ideas for learning more about TNOs, KBOs, and dwarf planets in the outer solar system...
  18. While I'm excited to see people working on these sorts of things I have to say, ESA, you need to work a bit harder on picking your names.
  19. Not quite The Expanse but good practice for converting all those other dwarf planets in the outer solar system into habitats. If the field of such bodies extends out into the Oort cloud as well then we have a LOT of habitat-building to do. https://arxiv.org/abs/2011.07487
  20. This is painful to watch. I just hope this is the catalyst for building a new radio telescope that's even better.
