- Comment on Is ice heavier than water? 1 week ago:
They talk about comparing the same volume of ice and liquid water, e.g. 1 cm³ ice vs. 1 cm³ liquid water, not two specimen of the same mass.
- Comment on [deleted] 1 week ago:
Did somebody already mention oil?
- Comment on Should I get the Measles and/or Mpox vaccines if I had them as a child? 1 week ago:
Eine Masernimpfung kann im Einzelfall auch bei Personen, die vor 1970 geboren wurden, sinnvoll sein, etwa bei besonderem Expositionsrisiko oder individuellen gesundheitlichen Umständen. Dies gilt insbesondere für Personen der Jahrgänge 1966 bis 1969. Eine solche Entscheidung liegt in der ärztlichen Verantwortung. Zu berücksichtigen ist dabei, dass die Kostenübernahme durch die Krankenkassen in diesen Fällen nicht automatisch gesichert ist und individuell abgeklärt werden sollte.
Again what learned.
- Comment on Should I get the Measles and/or Mpox vaccines if I had them as a child? 1 week ago:
The German governmental health agency (STIKO of Robert Koch Institute) recommends to get vaccinated if you’re born after 1970 and it’s unclear if you already have been vaccinated yet.
- Comment on Should I get the Measles and/or Mpox vaccines if I had them as a child? 1 week ago:
Usually, MMR vaccination isn’t refreshed every 10 years, but the ‘other one’ Polio-Diphterie-Tetanus-Pertussis is.
- Comment on Does each country have a book/library of the laws of the land that a commoner can consult to check if they're about to do something illegal? 3 weeks ago:
I would be surprised if there was a country that don’t have their all laws set in the paper form.
The anglosaxon school of law is more case-based than build on written law like e.g. in continental Europe.
- Comment on Sooo... This is happening on Imgur 4 weeks ago:
@tanisnikana@lemmy.world was so kind to link the video for us who don’t know.
- Comment on Could there be additional forces at super low energies? Could a new fundamental force be discovered anytime soon? + other questions relating to forces 5 weeks ago:
Current gravity wave detection works by measuring interference, if I understand correctly.
Not the Interference of two gravitational waves, but the interference of the (initially) coherent light of a split laser beam.

- Comment on Is there a practical reason data centers have to sprawl outward instead of upward? 1 month ago:
Unironically, I’ve had people telling me they save electric energy by inserting the angled Schuko plugs of their electric devices ‘upwards’.
- Comment on What are some free & open source fonts designed for or comissioned by brands? 2 months ago:
The Ubuntu font family is the first that comes into my mind.
- Comment on If you smoothened out the earth, how high would the water level be? 2 months 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? 2 months 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? 2 months 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? 2 months 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? 2 months ago:
Thanks for clarification.
- Comment on If you smoothened out the earth, how high would the water level be? 2 months 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? 2 months ago:
No, there are 1.4 billion cubic kilometres of water on earth (
V_w = 1.4·10⁹ km³). Earth’s diameter isD_E = 12750 km. The volume of the relatively thin shell of water is approximatelyV_w ≈ π(D_E)² t. Inserting yieldst ≈ 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? 2 months 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.
- Comment on Can someone give me some primers/resources on understanding politics in the Netherlands? 3 months ago:
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? 3 months 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? 3 months 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? 4 months ago:
There have been resentments against different groups of immigrants even before, e.g. Italians, Irish, or Chinese.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 4 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? 4 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? 4 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? 4 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? 4 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? 4 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? 4 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.
