I know this is a little off-topic but it's something that many could find incredibly interesting and is relevant to all of us (and some more than others): It also happens to be pure genius of a presentation! And if you happen to know anyone with cardiovascular disease, i implore you to watch this right now. Because there is an almost 100% chance that the advice they are receiving from their doctor is going to either not make things better or make their cardiovascular disease worse. But even if you don't have cardiovascular disease, this is still a must watch! As entertaining/shocking as it is informative.
Not really an ouch since last I heard one spectator is dead. Yep, one spectator confirmed dead. http://www.foxsports.com/motor/stor...hes-into-spectator-area-at-nurburgring-032815
Correct me if i'm wrong but that looks incredibly misleading. Grossly exaggerated to highlight the difference in surface heights. The height bar (to the right) would suggest so. I'm guessing "m" is supposed to be miles (as it cannot possibly be meters). Knowing that the diameter of the earth is around 8000 miles, +/-80 miles is no more than +/-1% from the mean. From the visual representation, that doesn't seem to agree. Another thing, total volume of water on earth is only ~0.13% of the earths total volume.
that's a very odd graphic, no point in trying to illustrate something in this way, the highest elevation on earth is a tad over 5 miles ( Everest peak ) not much more when looking elsewhere to take in to account the anomalies in the earths sphere. yes it's an interesting thought that water is a very thin skin around most of the planet, as is our atmosphere , Ive been looking into gravity lately (I remember asking adults about this when I was 6 years old lol without getting any sensible answers ! ) the earth/universe is a facinating subject but can keep one up late at nights lol
that would make more sense, although it's exagerated For visual reasons, interesting how someone has attempted to plot it in this way, it must be a result of a computer simulation & it's accuracy depends on how good the mathematics are still interesting though
It was measured via satellites over a number of years. So, pretty sure it's very accurate. Just not sure how it's representing earth's non-uniform gravitational field exactly. http://www.universetoday.com/116801/the-potsdam-gravity-potato-shows-earths-gravity-variations/ edit: Ok, it's just an illustration of the variation in gravity at different locations on the earth. Since the gravitational variance is so small (ofc), to visualize them, they simply made a abstract height map over the earths surface to represent the locations of gravitational minimums and and maximums. http://www.bbc.co.uk/news/science-environment-12911813
yes I found that, the sensors were described as "very sensitive " interesting the things we know hey it was only about 35 years ago that people were seriously talking about Martians ( creatures on Mars that may one day come to attack us ) at my school they showed us an out of focus round circle (pic of Mars) now we have a science lab on wheels there rolling around doing experiments ! I'll have to do a post of my view / explanation of gravity (& where it comes from ) etc if of interest (a tad late now though lol)
With my T500 that i constantly change Rims so im lazy to tighten the screw properly i know this very well :-D
