  Ah, ok.

• ⁨Comment⁩ on ⁨xkcd #3161: Airspeed⁩ ⁨⁨2⁩ ⁨days⁩ ago⁩:

  Isn’t one usually interested in the speed relative to the ground?

• ⁨Comment⁩ on ⁨xkcd #3161: Airspeed⁩ ⁨⁨2⁩ ⁨days⁩ ago⁩:

  The Pitot tube doesn’t work as the ballon is moving (more or less) with the wind, i.e. both pressure tubes in the Pitot tube are measuring (almost) the same pressure, resulting in measuring (almost) zero velocity.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  Definitely. But fortunately, everything here has the dimension length to the power of something.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Their idea is like throwing all material that is currently located above sea level into the sea which would subsequently increase the “sea level” as the radius of the sphere defined by the water surface, not the depth of the ocean on a perfectly spherical earth.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I’m fine with imperial units, as long as somebody stays in one unit system and doesn’t mix miles, yards, feet and inches, or square miles and acres, etc.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Tides are in the dimension of metres, the global ocean would be kilometres deep.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Thanks for clarification.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  As @huquad@lemmy.ml pointed out, @LodeMike@lemmy.today had an error in his calculation (radius squared instead of cubed). His corrected result, 1.7 mi also equals 2.7 km.

• ⁨Comment⁩ on ⁨If you smoothened out the earth, how high would the water level be?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  No, there are 1.4 billion cubic kilometres of water on earth (V_w = 1.4·10⁹ km³). Earth’s diameter is D_E = 12750 km. The volume of the relatively thin shell of water is approximately V_w ≈ π(D_E)² t. Inserting yields t ≈ V_w/(π(D_E)²) = 1.4·10⁹ km³/(π (12750 km)²) ≈ 2.74 km.

• ⁨Comment⁩ on ⁨How much more progressive are European views as compared to progressives in America?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  only possible with direct representation and without regional representation

  Multi party systems work also with regional representation if both approaches, regional and federal, are mixed.

  NE? It’s NL.

  Or NED.

• ⁨Comment⁩ on ⁨Do you think conservative feel the same need to burn it all down as everyone else felt when trump won again?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Voting successfully: The ballot was properly filled out and the vote was counted.

• ⁨Comment⁩ on ⁨Do you think conservative feel the same need to burn it all down as everyone else felt when trump won again?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Less than half of everyone who voted successfully.

• ⁨Comment⁩ on ⁨The USA prided itself on a nation of immigrant, heck even the Statue of Liberty says it. When did immigrants (US citizens from the old world) become anti immigrant and why?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  There have been resentments against different groups of immigrants even before, e.g. Italians, Irish, or Chinese.

• ⁨Comment⁩ on ⁨xkcd #3135: Sea Level⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Thanks. I didn’t know either that there are places, where the sea level does not rise and fall twice a day.

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  I’m won over on the idea that it would be outweighed by cooling effect of gas expansion from fart decompression.

  Did you already find information on how much pressure a colon can sustain?

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Not much, except the pressure involved is different and flatus contains more methane, carbon oxides and fancy molecules than the air we in- and exhale usually does.

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Farts are remarkably dry.

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  We are talking about mixing of gases, not the solution of a liquid in a gas or a solid in a liquid.

  Here, no bonding forces are broken as there are almost none active. Air as a mixture of gases at low pressure is, at least like I have learned in thermodynamics, treated as if its different components don’t interact with each other. For each component, the state equation is evaluated individually using its partial pressure.

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Of course. Otherwise this would qualify as a chemical reaction.

  I’d totally get it, if were taking about lets say vaporising of perfume or fuel. There, the bonding forces between the molecules of the liquid (van der Waals, H-bridges) are released, and thus stored energy is set free.

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Qualifies mixing of gases as dissolution?

• ⁨Comment⁩ on ⁨Do farts at least nominally increase the overall temperature of the room in which they are extruded?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Exactly, beside one techniallity:

  The process of fart mixing into ambient air generates heat.

  No, it does not generate heat. It carries a portion of heat from the body and transports it into the ambient air in the room. Almost simultaneously, an equivalent amount of air leaves the room to the outside. The increased heat of the air yields into an increased temperature in the room.

• ⁨Comment⁩ on ⁨Is there a decent, offline Android text editor/IDE for c# programming.⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Xed-Editor (GitHub) (F-Droid) is an editor with syntax highlighting and can be configured wirh IDE features.

• ⁨Comment⁩ on ⁨[deleted]⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  one might expect every child to have a body in between male and female as well

  No, one would expect the male children to grow to a body size somewhere between their dad and their mom’s brother.

• ⁨Comment⁩ on ⁨If I invented a shirt that caused cameras to be damaged when filmed/photographed, would I be committing a crime by wearing the shirt at events with cameras?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  If you could damage a camera by pointing it at something, the manufacturer would fix the issue before selling it, because no one is buying a camera that does.

  Recently, there were news about the LIDAR of Volvo cars destroying camera sensors when they were aimed into the direction of the IR laser beam.

• ⁨Comment⁩ on ⁨YSK that despite being outside of US jurisdiction, Lego has dropped diversity and inclusion terminology from its annual report⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  And while LEGO is a privately held company, they likely have US investors too.

  No, they have not. 75 % are owned by the family, 25 % by the LEGO foundation.
