>>6354568
you would also need to know the diameter of venus, of course.

>>6354568

>>6357302

>>6357379

>>6357384

>>6356902
>flying into the bermuda triangle
>>6356905
What is this one?

>>6357401
A tidal force from the Earth slows down the rotation the moon until they are tidally locked.

What I find pretty incredible is that the moon is perfectly distanced for eclipses.
There's probably not anywhere else in the solar system that's able to get as nice of eclipses as Earth

while searching I found this reaction:
Nitrogen Triiodide
http://www.youtube.com/watch?v=2KlAf936E90

>>6357401
It's very common.

The Moon didn't start out like that - initially, it had its own rotation.

But tidal forces - the same ones that cause, you know, the tides - pull in a direction opposite to rotation. Over many, many years, tidal forces slowed down and finally locked the moon in one place.

In fact, the Moon is having the same effect on the Earth. (Much smaller, however, because the Earth's so much more massive.) - our rotation is getting a few seconds slower every million years or so.

>>6357528
How the hell did they get the nitrogen triiodide onto those plates in the first place?

Is that smaller fish special for some reason? I ask since the diver seems to be trying to protect/save it from the bigger one (grouper?).

Pretty crazy nonetheless.

It looks like the fish is dead.
So what I think happened is he's a spearfisherman.
He speared his dinner.
Large fish took his dinner.

Not really. Induction heating only works over very, very short ranges.

It's the same reason those "wireless energy" charging pads only work when you actually place the device on the pad. They're both induction systems.

You shouldn't get so angry.

"A study published in 2011 suggested that a subsequent collision between the Moon and one of these smaller bodies caused the notable differences in physical characteristics between the two hemispheres of the Moon.[39] This collision, simulations have supported, would have been at a low enough velocity so as not to form a crater; instead, the material from the smaller body would have spread out across the Moon (in what would become its far side), adding a thick layer of highlands crust.[40] The resulting mass irregularities would subsequently produce a gravity gradient that resulted in tidal locking of the Moon so that today, only the near side remains visible from Earth. However, mapping by the GRAIL mission has apparently ruled out this scenario.[citation needed]"

>>6363064
It will literally only seat the bead, it doesn't pressurize it, it vacuum seals the bead to the rim, if you spray too much the tire will bulge out go WHOSH then suck back in on itself, the temperature drop after the WHOOSH is what causes it, then you gotta hurry up and get the air to it because if you don't it will loose the vacuum and come off the bead again

>>6363466
>why are they not running?
Actually, they are at first. They stopped when they noticed that they were far enough. In addition, they are probably a bit used to it, unfortunately it isn't that rare that something like that happens. My technology professor in high school once told me that the same thing happened during a visit with a class. Brix were shat that day.

It travels at the speed of sound.

>>6364146
>it's the shockwave from the explosion.
>It travels at the speed of sound.

it travels at the speed of sound in the medium it is traveling in... in this case it's the ground itself and the actual speed it travels at is faster than the speed of sound in air.

What I found interesting is that you can see the power poles (one has a transformer) with power lines vaporizing as the shockwave nears

>>6364181
why not the speed in the air?

>>6358845
it makes me wonder who's the smart mother fucker who came up with that

>>6364184
there is a shockwave in the air as well but it is traveling at the speed of sound in air (1100 ft/s)
If you look closely you can see the ripple in the ground traveling slightly ahead of the shockwave in the air.

>>6363692
>http://en.wikipedia.org/wiki/Four-dimensional_space
>In modern physics, space and time are unified in a four-dimensional Minkowski continuum called spacetime, whose metric treats the time dimension differently from the three spatial dimensions (see below for the definition of the Minkowski metric/pairing). Spacetime is thus not a Euclidean space.

Did you even read the intro to the link you posted? It specifically says that modern physics uses Minkowski space which utilizes a time dimension and the article never even uses the word deprecated, so where did you pull that from?

>>6364146
