    Important note, if you take a straw that separates into two split straws (kinda in a “Y” shape) that from a topological point of view is two holes, because one is for one of these paths, and the other is an extruded hole on the side of the first path. In topology you can’t break or mend material, but you can pull, stretch, squeeze and move it all you want. So you can move one of the split straw “legs” to the bottom of the whole straw, getting a shape similar to a “V”, it would look pretty much like a pair of pants. And topologically speaking it would be exactly the same. So… One straight hole for your mouth all the way down to your anus. Another two are there for your nostrils, that’s 3 already. The rest are for your tear ducts, which have two holes on the edge of your eye, (so four in total) which merge and then connect to your nose.

    So a human, from a topological perspective, is just a seven holed doughnut. Also Vsauce made a great video about that, with pretty great animations.


  • No benefit? No, of course not. But for more money to the shareholders of the oil and coal companies which some politicians either are or get payed by. OF COURSE! They will do it gladly with a smile.

    Renewables aren’t funded anything close to what governments of any country spend on oil and coal companies, and that’s for the benefit of the very few people who own them.

    Didn’t we already figure out the whole climate change story way back long ago? And the only reason why we didn’t do anything about it were studies funded by the oil industry so that they absolutely have to show there was “no link” between our CO2 emissions and the global temperature? Because I’m pretty sure that’s the story.
