0/0 is an indeterminate form, meaning you can define an operation that is equivalent to dividing zero by zero in many different ways, and it can give you any answer that you like. What you get depends on the "strength" of each zero, in the following and very handwavy sense which might make...

33841 have you heard about sounds associated with aurora displays? http://forum.spaceengine.org/viewtopic.php?f=11&t=296&p=25428#p25428   :)   (For discussion of meteor induced sounds, but aurora may work in a similar way.) On an unrelated note, today I got out on a proper adventure in the ...

33839 Well, I am in NY so that is not a problem for me.....large price tag, are we talking four figures here?  More like $400-600, while their 8" globes are going for $80. On the large globes the voltage is easily adjustable with a dial so you can get a wide range of effects, and their frequen...

I discovered them from a company in Vancouver, BC, "Aurora Plasma Design" ( website ) who specializes in these. However, they only ship to Canada and the US at the moment. These are very large (15" or 38cm diameter) and high quality globes, made largely for science museums, and they h...

33831 I dont even mind some property destruction 33834 I agree, I dont like property damage either So... do you not mind it, or you do? Being less bad than murder or war does not mean it is not bad. To me, it is simply unacceptable. It is not protesting against wrongdoing, it is a wrongdoing. It is...

33818 Maybe there will be no significant new outbreaks, but there is a risk, a risk that was judged high enough to close down cities.  If these marches cause no uptick in covid-19 at all, it's strong evidence that the shutdown was an overreaction.  If there is an uptick, congratulation, protesters,...

Some more photography with a new plasma globe. This is definitely my favorite plasma effect so far, with the blue-green colors caused by a special mixture of xenon, krypton, and some other trace gases. https://i.imgur.com/mcN4VXG.jpg https://i.imgur.com/bX8Aq1a.jpg https://i.imgur.com/yj5s3qG.jpg h...

What Japan did and what the Soviet Union did were pretty similar, leaving aside that with Chernobyl the magnitude of radioactive material released was profoundly greater. Both countries estab...

Unusual weather

33716 The best display here that I've seen was this: That's spectacular. I dream of seeing arcs near the anthelion, those seem so surreal... Here ice halos are somewhat common in spring and summer when we have high altitude crystal hazes, but usually it's just the 22° halo and parhelia. I once many...

Unusual weather

Nice, thanks! I was first thinking of a pollen corona as well, since I didn't really know what else it could be. However, it lacks the more vivid colors and brightening around the Sun that is typical of corona. But when I searched around for info on smaller ice halos, I couldn't find anything, so I ...
