Is the Moon a Planet or a Star...the debate rages on

kceaton1 says...

If the conversations were like this the entire time they tried to sell things on these types of 24/7 channels, I just might watch them. For the comedy, and to get some of the best fracking video clips in the Universe to play and re-play...

I'd love it if they had to label a really complicated star system that has three stars (two that are satellites--and obviously if this star system existed it would fall apart really fast or if it achieved equilibrium then it still has, as I/you can imagine, amazingly low chances of staying in this semi-stable state; like our own system...which IS falling apart, but it's just doing it at a moderately slow pace); then add in planets revolving around the stars, moons around the planets...and it will become hard to decide what is a satellite or a planet in some instances (as it may count technically as both).

Throw in a large debris field (an asteroid belt, but with "chunks" the size of very large moons--like 1.5x the size of our own Moon) and an Oort Cloud, again with comets that are as big as small moons/satellites and they will literally have no idea how to label anything.

The sad part is that I bet a very large segment of our population would also have the same problems with this task.

Sometimes, it is bad that we have Google...because some people will rely on it too much (especially so if it's students--those going through K-12, or similar setups in whatever country you're reading this from; but, not college...though problems do exist there, but it gets FAR harder to "lie" your way to a degree, etc...). However, if you are older and you use the Internet to look up things you don't know and if you remember any of it--this is when the Internet (or "Google") becomes a great tool and boon for humanity.

Nothing is better than spreading knowledge and wisdom.

U.S. Space & Rocket Center in Huntsville

You like Saturns?

My dad blew one up. And a Titan.

He was a Range Safety officer with the Air Force in the late 1950's, early 60's. Would blow up missiles that were going off course, so the debris would fall in safe areas. Blew up LOTS of missiles.

I have a really cool image of his going away present when he left Cape Canaveral -- a cartoon with him astride a rocket, in space, over Cape Canaveral. There are silhouettes of all the missiles he blew up over his time there on the side of the rocket he is riding -- with hashmarks for HOW MANY he blew up.

It's really cool.

He BLEW UP A SATURN. Which isn't as powerful as the Titan he blew up!

O wow, long time no sift, sorry. Once my account got locked at work, I just never visited anymore.

But I got to head out to the rocket center for the random acts of intelligence show, it was pretty awesome. All the video here is just from one of the 2 building...so ya, worth a trip!

The Saturn was more amazing than I had imagined. I always knew it was big, but seeing it sprawled out on the ceiling is indescribable. Imagine a 30 story building filled with explosives, lit on fire and hurling itself into space...because that is what this is. I have lots of pictures if people want to see, I will surely share them.

Glad to see sift is still alive and well. The sift, specifically a video by @dag, basically changed the course of my life and I am now pursing a degree in nuclear engineering, so thanks for that. Anyway, if I can figure out a way to change my name, perhaps I can once again partake of some sift action.

Airboats (used in swamps) also have Hugh Jass fans in close proximity to the human driver - that problem has already been solved.

And because they are lighter, these would need less downward thrust than a helicopter, but I agree that debris propelled by downwash could be a hazard. (but even the entire fleet of huge Chinook helicopters' downwash only caused a few minor injuries over past several decades in service.)

Dutch journalist Jeroen Akkermans keeps uploading scores of pictures taken at the MH17 crash site to his Flickr account. No corpses, just debris -- no warning neccessary.

A few interesting pictures, if you don't mind amateur forensics:
- left wing, top side: damaged by debris coming from the fuselage at an outward trajectory
- window panel, aft-most cockpit window, port side: shredded by shrapnel, downward trajectory?
- second door from the front, port side: no damage from shrapnel or debris
- port-side hatch of the forward landing gear: no damage

So, explosion in the foward-left quadrant, above the cockpit?

I know, I know -- wild speculation, utterly without a point. But it's infinitly less depressing than looking at the latest pictures from Gaza. Bad days to be a news junkie...

Edit: rear door, starboard side -- no damage

Beautiful Tornado Bears Down On A Trailer Park

AeroMechanical says...

Thanks Dolbs, that's good to know even if I will almost certainly never encounter a tornado. So, windows rolled up then. After further thought, I think the truck probably is the best idea in this scenario. Belted in and covered with a heavy blanket to protect you from flying glass should the windows break (and it's safety glass anyways) or other small debris, would be the way to go, or just curled up in a ball against the firewall if that's the only option. In the truck, you're insulated from lighting strikes or downed high tension lines, and it would provide reasonable protection from small whirling debris. You also have the mobility option should that need arise.

Granted, the truck could get hit by large missiles such as tree trunks, other cars, fat old ladies, cranes or other heavy machinery, or indeed itself be lofted hundreds of feet into the air. If any of that sort of thing happens, though, you were screwed anyways.

So, when it comes to this, I'm not really sure this is EIA in the truest sense. Given the (apparently) 30 seconds they had to plan, I think they made a reasonable choice among the options available to them. After all, it's definitely a situation where an okay plan now is better than a brilliant plan in five minutes. And yes, they probably should have come up with a plan as soon as they realized they were moving to a trailer park in ND, so a bit of EIA there. At least they kept on top of their priorities and realized the very first item of business was to film it happening, and I commend their presence of mind to hold the phone properly even in such a life-and-death situation.

Of course, since we're betting on the tornado not scoring a direct hit anyways. It could be that under a bed or in a closet in the trailer might have been just as well (losing the mobility, of course). Maybe having a trailer collapse on you is bad.

I dont' know why I find this scenario so fascintating to dissect.

I'd be more worried about the vehicle flipping, or being picked up and thrown. They weren't wearing seat belts so both scenarios would be pretty serious, if not fatal. Additionally, debris falling on the truck or more aptly, how some debris can be picked up and turned into a projectile that can penetrate the metal and/or windows causing great harm.

I would wager that in most cased to break tempered glass, the outside pressure would already be high enough to roll/flip the car. But to be safe, you're better off cracking the windows anyway.

Well, the truck is a truly terrible idea (*under* the truck might be the best of bad alternatives). Perhaps we need to go down the "there ought to be a law" route and mandate that the owners of trailer communities provide a tornado shelters. They can't be that expensive to build.... a hole in the ground, some cinderblocks, some steel I-beams.

Here's a question for the experts. If, for some reason, you're stuck in your truck. Are you better off with the windows rolled down, partially down? Fully up?

My very superficial understanding leads me to suspect that if the windows are closed, you're risking the pressure differential exploding them. On the other hand, they will protect you from a lot of flying debris (to an extent) if they are closed. Maybe partially closed?

I guess when it's all said and done, it's EIA. If you live in a tornado prone part of the world, and you live in a trailer park, you should probably have some sort of plan worked out in advance regarding the best course of action.

Actually, to practice road ride, you MUST ride in a group. There is a huge group etiquette and not to mention learning to pass, take over, draft, follow etc can only be learned by actually doing it.

Most road groups like that ride on long stretches away from town. It's not like it's the end of the world to pass them, safely mind you, by waiting a good 30 seconds.

But you're right, roadies are lame. Fat Tire for life!

BTW, should be noted that most cycling experts will attest that most cycle lanes are more dangerous than not having them. Between all the road debris and poor maintenance, it's sometimes the worst place for us to be.

Which means I should also point out, that cycle lanes does not mean we're required by ANY law to use them. They are basically a courtesy for slower solo riders. In Florida they tried passing a requirement law, and it hit a lot of walls due to liability issues. If a cyclist is in the bike lane and there's an obstacle, and they hit it and get hurt, the city/state is completely 100% liable for any injuries or deaths.

You mean typical ROAD biker.

My experience has been that mountain bikers (who generally view being on the road as a necessary evil to get to a trail) are careful and courteous.

The lycra brigade, OTOH, all think they're in the fucking tour de france and feel the need to practice riding in a peloton. What especially annoys me is when there is a cycle lane and these idiots ride on the outside marker so that half their body is in traffic.

Holy smokes. That's sort of like saying, Roommate's cousin had a death wish LOL
How do you NOT become a smoking spot in a wall/cloud of flying debris with that much power at your disposal?
