My Dad and I were on a fly fishing trip with a guide in a long canoe-like boat on a river. When the storm came up behind us, we pulled to the side of the river and took cover under the branches of some small overhanging trees. I wasn't very concerned, as the storm wasn't all that big and I'd been in similar situations before.
When it started hailing, I became a bit more worried, but I was still reasonably relaxed. Then I saw an extremely bright flash, screamed, and ducked. My Dad and my guide never heard the scream because the thunder was instant. It took me a few seconds, but I turned around to see if they were ok. They were, and they asked me if I saw where it was. I said that I just knew that it was close. They told me that it was about 3 feet to my right, and it hit the water (my Dad said he saw a hole in the water).
I definitely felt something from it, but I can't really describe what it was. I'd pay a lot of money to be able to see a video like this of that strike.
I'm pretty lucky to be alive/not disabled for life. Don't let your misconceptions about lightning put you in a similar situation. Read NOAA's guide on lightning safety: http://www.lightningsafety.noaa.gov/
Could this be what the brain is doing? A group of neurons get excited (some concept or thought), and a distributed spatial search happens electrically starting at the source of excitation (literally brainstorming), until it finds the best pathway to connect to "ground" (reasoning), at which point the pathways between "source" and "ground" stay continuously excited for a measurable period of time (the ephiphany moment, learning is happening via hebbian). "Ground" is whatever that causes the source energy to drain, such as the epiphany of a solution, which makes the solution appear obvious.
> These electrons are zigzagging through the air as they meet paths of easier passage through the air--paths with a lower dielectric strength. Each stroke of a lightning strike is usually about 50 m (150 ft) long and lasts about 1 to 2 microseconds with a pause of about 50 microseconds before resuming another stroke in a slightly or significantly different direction.
(Why link to that blog? It offered nothing extra to the videos)
I've seen 1000fps on prosumer cameras, before, but are we close to 5,000 even on sub-$1000 cameras?
The biggest problem I see is storage if you hack something together. Not just raw storage, because that is an issue, but how fast you can clear the buffer and get the image to disk.
So, is this illegally copied material on the top 1 spot of HN?
