Which one is the « catoid » there?

Of course we do. What I wonder is if there is any (inverse) correlation with aphantasia.

That was exactly my point, that an apple coming from a black hole may seem problematic but so does an apple coming from the Sun. I don't see an essential difference regarding the "reversibility" of the physical process (but I

I think you don’t understand my point. Someone wrote “If you saw an apple spiral out of a black hole, wouldn't you suspect that you were watching a reversed video?” I replied “If you saw a comet coming from the sun, or a meteorite comi

Sure, nothing in the laws of physics prevents a celestial body from distancing itself from the Sun or from the Moon. But it would like suspicious! Wouldn't you suspect that you were watching a reversed video?

Every object has been subject to forces other gravity at some point. And the point is that sometimes comets do indeed fall into the Sun. If you object to people calling that a comet that’s fine - we can use whatever name you want.

If you saw a comet coming from the sun, or a meteorite coming from the moon, etc. you would also find that suspicious.

There is some objective nature to the operational definition of entropy based on an experimental setup where you fix the volume and measure the temperature or whatever. And this is related to the statistical mechanical definition of entropy

> Entropy is not a physical quantity, it is a measure of how far a system is from equilibrium. That’s funny because the original thermodynamic entropy is defined only for systems in equilibrium.

The same microstate will have different probabilities depending on what are the constraints or measurements used in _your_ description of the system. If you choose to describe the system using its microstate - and you know it - there are no

p_i Edit to add lots of words: In the definition of entropy S := -k_B sum p_i ln (p_i) knowledge about the system enters the equation in the p_i terms. The other term is a constant so it’s not like there are many other choices to link the e

Entropy is about the state - not about “outcomes”. “All we can know” is the precise state - at least in principle - and entropy is zero in that case.

You’re not wrong but what did the commenter above meant with “50 hours+/week”? Weeks have three times as many hours. Years also have many more than 218 days. Anyway I found an official survey saying that 40% of them work more than 50 h

It seems that 20% of employees in the private sector are "cadres" and half of them are on "forfait jours". That makes around 10% of the private sector employees working 218 days per year without the 48/44 weekly hou

> 218 rest days per year (including weekends, holidays, and RTT days) Wouldn’t that be nice, 218 rest days? It’s 218 working days.

I don’t fully understand your comment but it seems that we agree that the answer to “does that create incentives to try to keep employees longer-term in order to make them more cost-efficient?” is “no”.
