I love the details with the muskrat family. The two adults have a child, the child grows up and graduates (the mum either died or left), and the child moves out (the father died I think), and when the muskrat is looking at the billabong it thought that a family of other muskrats had died. Amazing attention to detail.

You studied geography so that you'd know the name of the countries outside your border or have the knowledge in how to find the said country on the map. And the name of your states/provinces/region.

Hey, at least when some head of government say lets go to war with country A, you'd know where that country is and its geopolitical relation with its surrounding countries and its problem with your country.

@IWannaBTheGuy 7 лет назад

Temperatures on mars make it improbable for other liquids to exist outside of the poles. So it's almost certainly water.

@khosrow 7 лет назад

The northern pole is made of 50% frozen water and 50% frozen CO2. The southern pole has some specks of water. So there definitely is and has been water on Mars. The question is how much. We don't know if those rivers have been formed by water. Maybe it was methane or liquid CO2 from all we know.

@5heeshi 9 лет назад

Verdiss The mythos is only a small part of religion. For many religion helps deal with pain and problems. Helps people be charitable and kind. The modern atheist movement seems to lack manners, patience and kindness because there is nothing there. A world without religion would not be a utopia as atheists dream about. It would be 'the strongest survives' where morality takes a back foot to statistics. Also atheists need to stop hijacking science like it's the same thing. It's religion vs atheism not religion vs science. That's like religion hijacking a field and every time that field does something we be like "Fuck you atheists"

No the child grew up, and one of them passed away since only one of them are using a cane and look old.

As my Dad once said, "Following the path of least resistance is what makes men and rivers crooked. "

@carultch 9 лет назад

Alan Lambert It is a myth that electric current takes the path of least resistance. Electric current takes all possible paths, of all resistances. It is just that it divides itself up onto each parallel path, inversely proportional to the resistance of that path.

@LordDragon1965 9 лет назад

carultch True, I was referring to men (humans of either gender) and rivers, not electrical current.

@lucaseddsilva 8 лет назад

Alan Lambert Your dad seems to be a wise man!

@lucaseddsilva 8 лет назад

carultch Maybe that's the reason why electric currents aren't crooked at all, they can be shockingly straight some times...

@abcdefoff3307 4 года назад

1:28 It's called a thallwag. The strongest thallwag is the one that is not in contact with the river banks. This chapter is honestly the easiest chapter of Physical Geography. I used to be able to explain rivers, meanders, waterfall, gorges, deltas, braided rivers, etc in one go. I wish I could still do that. I felt so smart back then.

@TigruArdavi 3 года назад

*wrong* The word is thalweg and it is the line that joins the lowest points of the river bed's cross section (or on land of a valley). It derives from the German geological term Talweg, literally meaning 'valley way'. It is never where the strongest current is, as that is slowed down towards the margins of the bed due to friction. The lineof the strongest current is called the current thread.

The Dutch version of that stretch of river that become obsolete was Hoefijzermeer. Litterally translated Hoof-iron-lake. A hoof-iron is a horseshoe, and it looks just like that.

(It's a Swiss joke btw.) :-)

My question: did the rivers on Mars, since they're subjected to different gravity, have a different ratio of periodicity of their curviness to width?

@jonathanfowler2932 7 лет назад

Fun fact: A river's distance (line following stream from point A to B) divided by the river's displacement (straight line from point A to B) is Pi. Or at least sits near Pi, and the mean of all rivers is extremely close to Pi. See Numberphile if you care to look into it.

@GameProfessor 5 лет назад

Assume that river's shape is close to a perfect S shape then it is simply perimeter / diameter = pi. Thanks for the fun fact.

@sodr7440 5 лет назад

At first i did not believe what you've said and checked it (by using google maps) and the results were shocking! -just kidding, it was no where near near pi, unsurprisingly they are around 1.5 to 4.25 (of course my calculations might be wrong)
