You could have a navigation system without the GPS satellites. You'd just need the map data, a compass, a way to tie into your car's odometer, and some way to orient the system one time... the latter could be a person inputting the approximate start address, or a camera pointing out the window reading street signs once in a while. The magic of smartphones is that they got huge economies of scale for equipment that can do all these things, driving the price down from thousands of dollars, to trivially inexpensive. The business models of subsidizing the equipment with the monthly service plan, and manufacturers selling at a loss to try and break into the lucrative market also greatly help drive prices down to the point you can pick one up for $30 today.
I have heard that adding very hot pepper (cayenne, for example) to bird food will teach mammals to stay away but will have no effect on birds. That is one of the reasons peppers are hot.
Ah, the beauty of space - where atmospheric drag is not a factor. These ships may move in and out of the atmosphere, but their main job is to perform in the near-vacuum of space.
I think there's a missing step of validating the wind tunnel simulator for the types of models he has. He reports a real-world coefficient for an F-4E. If he took a model of the F-4E, to the same quality as the Star Wars models, and put it in the same simulator, does it also have a drag coefficient of 0.02?
Koko spoke to the world and was a true ambassador for the Gorilla Foundation highlighting the plight of the Western Lowland Gorillas. I truly hope Dr. Patterson and the Foundation continue to work on behalf of the Gorilla and end the Bushmeat Trade in Africa Poachers and habitat loss are the Gorilla's biggest threats.
Ms. C, have you considered proposing topics to Tom Scott: prepping script material, doing location work and general production? Might be the start of a beautiful friendship.
No matter, if a labeled, service anything comes up and directs your attention to anywhat, call 911 and keep away. Your ability to help is trumped by your lack of knowledge.

Has anyone tried this technique?
