So not one of our resident self-declared science experts can identify one of these phenomena by name? Isn't that special.
Oh, I got most of them, but as you posted no context, I thought it was just another of many "pretty-interesting picture" threads. 1. Green flash, most nautical people know of this. 2. Bioluminescent plankton. Once again, anybody who is a SCUBA diver and done night dives knows of this. 3. Internal waves. Once again, something a sailor would know. 4. Electron diffraction. Especially fun when they are being watched, or there is a cat in the box. 5. Lightning sprites, ok. 6. DSOTM. Which still holds the record for being on the top 200 album listings for a staggering 736 weeks (March 1973 to July 1988. 7. The blue glow of a nuclear reactor. Seen that at EBR-II. 9. As I said, somebody refused to replace their zincs. 10. Forget the name, is back when physicists debated if light was a particle or a wave. 11. No idea, are you trying to imply something about lens coating or polarization? Maybe I recognized so many of these because of my background in sailing. Or simply because I would rather watch documentaries about science than watch TV, and have a strange sense of humor.
Not bad! 1 and 2 are correct 2 is SUCH a beautiful photo! 3 Is a satellite photo of a freak wave forming. They were once thought to be mythical. But eventually we measured them and saw them from space. In the photo we see one mechanism for freak wave production: Multiple waves are coalescing which creates one big wave. This is how you get one giant wave on a calm ocean that comes out of nowhere. The reason they were once dismissed is that all wave models were linear. In order to understand freak wave formation, we needed non-linear models. 4 - I was just going for diffraction. But I'm guessing you searched the image because I believe that was electron diffraction. LOL 5 - Sprites is correct. So many types of atmospheric phenomena have been discovered in recent years Sprites Jets Blue jets Blue starters Gigantic jets Observations ELVES Trolls, Pixies, Ghosts, and Gnomes
DSOTM yes LOL! But I was going for refraction 7 - what is the proper name of the blue glow? 8- No answer? 9 - what is the name. And while that is a reasonable answer, there is another which is what I was actually going for. I believe it is a photo of the latter and not the former. 10 is a tough one. But it is a common phenomenon 11 - what does the coating do?
#4 is a classic example of how electrons behave differently when observed. A key point in quantum physics. For 7 and 8, do not recognize it, do not care. Knowing the name itself without researching it is not as important as knowing what they are in most of these cases. For 9, I want to say it is "Galvonic reaction". Once again, any sailor knows about this. It is why we put bars of zinc on boats, to prevent this from happening. But knowing the name is not as important as understanding the process. We put zinc on boats in salt water because the reaction will corrode the zinc before it corrodes more important parts of the boat. Like the hull, rivets, and the screws. You only see corrosion like that if somebody forgot to change the zincs. Look, I can see that you are trying to show you are smarter than anybody else. But realize this, I answered each of those off of the top of my head without having to research it. And yes, I know what you were trying for on number 4. And while you could have used a great many images of a prism, you actually used Pink Floyd's "Dark Side of the Moon" album artwork. I did not have to search anything, that is an iconic image to anybody of my age. I have even had it on shirts and hats over the years. And once again, it shows how belittling and condescending when you try to accuse somebody in their 50's of not knowing what one of the most iconic images of their generation is. I can also describe every album cover by The Beatles (even the "Butcher" cover), as well as by the Police and most from groups ranging from Rolling Stones to Weird Al. Of course, I know that the very concept of "Album Art" is lost today, where nobody buys "albums", or even anything even close to that. But showing somebody my age and thinking we would not recognize it instantly would would be like showing an image of the WTC to anybody over 30. Then saying they had to do a search to know what it was. Oh, and bioluminescence is even more lovely when experienced first hand. Ask any diver that has their AOW certification or has done night dives, I am sure they have all experienced that.
It is a typical diffraction pattern. It could be almost anything. It is most certainly NOT unique to electrons. And they don't behave differently when observed. They behave differently depending on if you measure for a wave or a particle. You don't know what they are. A blue light is not the answer. And you didn't give any answer for 8. So just say you don't know. No it is cavitation. No, I am trying to show that people here who think they know more than actual scientists really don't even know the basics. I am actually a physicist so I should know more than most people about that subject. But when I try to share my knowledge gained over many years of hard work, I end up having argue with internet ego jockies and self declared experts. For example your answer about electron diffraction shows you have no knowledge of the subject. But you still argue. And you get arrogant to boot. It is pathetic. And this is why we have so much nonsense surrounding serious issues like climate change. People with no training or expertise think they have all the answers.
And for the record, the diffraction pattern is determined by the wavelength of the wave, which is a function of the momentum. It doesn't matter if its photon or a proton or an electron or a baseball...or a planet. What it is has nothing to do with it. All that matters is the momentum. That determines the diffraction pattern.
Actually, on the screw shown I do argue. I know what cavitation damage is, it normally is on the leading edge. However, that one also has extensive pitting and corrosion where the blade meets the shaft, that is indicative of galvanization damage. One can cause issues at speed, the other can lead to a full separation of the blade from the shaft and leave a boat dead in the water. That was a real problem several years ago, as some ships from Korea were fitted with screws from metals that were not approved in salt water, and the ships had no zincs. Just as seen in the image, where the blade met the shaft was extensive pitting, which was resolved when zincs were installed on the ships. Maybe a lot of the problem here is that you have little to no real world experience. Where as I have experienced this first hand, and even replaced zincs on ships. Cavitation is one issue, but the galvanization is the much more serious one as that is likely causing corrosion on all metal parts exposed to the water. If your answer for the problem is simply cavitation, you might have just cost somebody their boat. They might simply accept what you said because you are a "physicist", and put a shroud in front of it or replaced the screw itself for one of a different pitch or material. Meanwhile, the rest of the metal components would have continued to corrode as they had no protection. Including the new screw you had them install. Tell me, how much experience do you have working on boats or ships? You throw up some picture and it tells you one thing. But that is only part of the problem, somebody that is really experienced can often see other things. You are like somebody that sees white smoke coming out of an exhaust pipe, and think a car just needs to have the smog system repaired. Where as I would walk behind and immediately smell the exhaust. Because I know that is actually the common sign of a blown head gasket, and I would be seeing if I could smell antifreeze. Go ahead and play your little ego games, it means nothing to me. You whine I do not know the "actual names". That is just simple arrogance, and I have no time for that. Oh, and here, school yourself on "Sacrificial Anodes". We generally just call them "Zincs", as that is what they are normally made of. And my not remembering off the top of my head the technical name for them does not mean I can not diagnose the much more serious problem that ship has. Stick to your theoretical mind games, real world is obviously not your best area.
