Yes. One place in space has different temperatures. I would assume even individual particles are not distributed by a Maxwell distribution, so the concept of temperature is hard to apply. The background radiation has one temperature. If you add the sun, however, you already have a problem as the sun radiation is not in thermal equilibrium. So depending on how you look at it, you get different temperatures. The particles have a high energy, so also a high temperature. But they are so rare, that radiation is the dominant mode of heat transfer and determines the temperature of a thermometer placed in space.

I think it is actually the other way around. You can consider the air inside the balloon to have internal energy from the heat. And additionally you have to make room for the balloon in the atmosphere, so you have removed the atmosphere from the volume the balloon takes, which also needs energy. If you consider both you arrive at the concept of enthalpy (H = U + pV), which is very useful for reactions in the atmosphere as pressure is constant. For this example it is not that useful as outside pressure changes when the balloon rises.

Another way to see it, the pressure has no “real” energy. In a ideal gas, the only energy comes from the kinetic or movement energy of the atoms. Each time a gas molecule is hits the balloon envelope it transfers some momentum. The cumulative effect of the constant collisions is the pressure of the gas. If the balloon is now expanding slowly, each collisions also tranfers some energy, in sum building the work the system has to do to the atmosphere. Leading to a decrease in internal, so “real” energy in the balloon. This corresponds to a decrease in temperature.

The stratosphere is heated not by the ground but directly from solar radiation leading to higher power input at the upper layers. So the top is hotter and now convection never starts and you get no cooling of the air when rising.

While I agree in general, one point is a bit to simplified in my opinion

In other words, there are fewer air molecules per cubic foot (volume of air). The molecules are farther apart and can hold less heat energy. Because “heat” is what we say when we mean molecules are moving around.

Less molecules mean less heat, it has nothing to do with the temperature, if you just decrease the density by removing half the molecules, you have the same temperature.

It cools down because it expands adiabatically. Consider a very thin balloon filled with air which is warmer than the surrounding. This now rises up, but as it does, the pressure decreases, causing the balloon to expand. During this expansion, the balloon transfers energy away from itself, because it has to push away air, to make room for expanding in the surrounding. This work cools the air inside the balloon. Assuming the air inside is dry, it would cool around 10 °C per km it rises. Now if you think about it, the balloon just stopped the inside from mixing with the outside. If you look at a large “piece” of air, it does not mix very fast, so you can remove the balloon and just consider what happens with warm air heated from the ground.

Now this does not mean, it has to be cooler when higher up. The same points hold, inside a house, but there it is often warmer when higher.

The best explaination is when looking where the heat comes from and goes too from the air. The atmosphere is mostly heated from the surface of earth, so the bottom and cooled from the upper layers. So naturally it gets hotter where it is heated. The question is now by how much? There are three modes of heat transfer in the atmosphere: radiation, conduction and convection. The first two are very slow. Connection is fast but has limits. Consider the piece of air, if it rises, it cools. So at some place it may be the same temperature as the surrounding air, so it stops rising. This means the convection works only when the air gets cooler by 10 °C/km going up (~6.5°C when the air is moist and precipation happens). So this temperature gradient is observable very often.

Yes colors have a meaning. However, they change ober time and culture. So why not use the word which describes exactly what we mean?

I agree, nowadays blacklist/whitelist has practically nothing to do with skin color. However i do think it is weird to use the same words for describing the appearance of people and good/bad.

Well i would be indifferent to the renaming to primary, because it doesn’t really matter to me what they call their branches, as long as it is descriptive. primary also conveys the meaning. I would probably continue using main/dev because i see no reason to change.
I am not someone who says “You should change this!”. I just say, think of it, there are some reasons to change and the only reason to keep it, os that we did it always like this. I think there are reasons for selecting better words. And I am only annoyed by people who are outraged by things others do, which does not really affects them negatively. I get it that someone wants to continue using blacklist, master, etc. and I am ok with that.

Even ignoring the question of racism, they are still stupid names.

Imagine teaching a child about this and it asks: Why is white allowed and black not? The only answer is, because it is like this for a long time. If we name them allowlist and denylist, it is obvious to all English speaking people. Shouldn’t we strive for descriptive names in programming?

However, if you use names whitelist an blacklist, you need to make the implicit connection white-positive black-negative. Yes obviously this does not make you racist if you do this in programming. But is it good?

Yes that is the point. They made the choice to change their default. You can still make the choice to name your branches, especially the main one, as you like. Setting it for a project is less work than complaining about it.

I cannot recommend mindfulness enough, as already suggested by many others in this thread.

I think, you said you are already in therapy? In this case, I would definitely talk with your therapist about this and things you want to adopt beforehand. If you want a simple concrete tip, you could try the “mindfulness coach” by the US department of veteran affairs. I liked it a lot and the apps from there get good privacy recommendations from mozilla.

I am a bit suprised by the many people recommending to just stop giving fucks. Is this what you really want? Or do you just want avoid the emotions of taking control?

You do not need to be that hard to yourself when your feeling “wrong”. Yes it is probably better for yourself if you don’t overreact. However you cannot really cotntrol your feelings. So it is still better to accept your anger. First, as you said, it drives up the frustration, because now you are also worried about your feelings. And second your original emotion wants to be “noticed”. I read and experienced a few times myself, the “wrong” emotion disappears often quickly when you accept it. It is an essential concept of mindfulness, to accept your emotions.

Edit: As far as i understand it and experienced it, saying to yourself “no i shouldn’t be angry about this” won’t change your thinking

I don’t know your exact experiences, but I had a similar feeling in the past. However, recently I noticed it was a lot of how i behaved to them. I started speaking more openly with my male friends and noticed, they also value my emotions. The main difference was, that my friendships with women started on an emotional level making it a lot easier to open up for me. With my male friends, I needed to just say how i feel, which i have not dared for a long time. My own stereotypes probably played a larger role than the gender of the people involved.

However as others have said, if they do not take you seriously when you open up, they are bad friends. (Edit: Bad friends is a bit harsh, more like friends for having fun together, not to rely on. This is also nice even if it can be hard to accept)

Don’t be so pessimistic about it, i thought as you do. However, if you meet a person fitting to you, it is of no importance that you have no experience. I had my first date recently, probably ten years later than most. While i was embarrassed, it was no problem for her and she was very considerate to me.
