  • This post and thread gives me (back) so much hope. I always hoped for something like described here. But I never came anywhere close and so I have lost the hope over time. I was thinking in the direction of “I just want someone to share my life with. It will work out to be ok somehow.” But some recent events and post like this give me back the hope to find a the person I really want to share time with. It also brings me the motivation to work on myself, so to be more like I would like to be. Thanks you all.

    The more self-sufficient you can be, the fewer societal resources you will take up, which could then go to someone else in greater need. That’s my perspective at least.

    But the more self-sufficient you are, the more resources of yourself you need to supply yourself. So you can provide less societal resources. If you do not need to provide clothes for yourself, you have more time caring for elderly, etc.

    As another view, the total resources need does not directly change by changing who does what. The advantages of helping each other are in the OP. At some point however, I would think, the overhead of organization grows so large that it may not be worth it anymore. Just think of the amount of work put into “useless” administration in many countries. But in a 30 person village, this is probably negligible.

    Edit: Thanks for helping other people on the feet!

    I think your post is exactly what is criticized by OP. In the first part of the post it is explicitly stated men should not talk over the fear of women. A message like yours seems to blame people just because they criticize the way of discussion in some places. I think it is obvious that men are influenced in a possible negative way, when they are always seen as danger. At least for me it probably contributed to my low self esteem, especially in all sex/gender related topics. I think, we as men do so much harm, I don’t want to take part in this. But i took it to the extreme, so I was ashamed of everything sexual about me. But as OP said, all of this doesn’t invalidate the feeling of any woman. But for example this situation here is not governed by fear, still it seems you can’t discuss the social effects of this sentiment “against” man, without discrediting the other side. Sure, violence done mainly to women is the most important topic. But if men always get portrayed as danger, I can understand some are open to other, more misogynist worldviews.

    Ja das stimmt, da hab ich aus der Physik kommend zu anwendendunsorient gedacht.
    Aber für die Frage ob komplexe zahlen gebraucht werden, reicht es, eine isomorphe alternative zu haben. Die komplexen Zahlen haben auch nicht mehr mit Quantenmechanik zu tun wie die Matrizen, nur sind sie leichter handzuhaben.



  • But also learn to feel your feelings by yourself.

    I agree completely with this stance

    If you need to talk a lot about your feelings, especially the deep stuff, talk to a therapist. That’s not brushing you off, it’s what therapy is for.

    While I agree that therapy can help a lot in those situations, I don’t think these talks should be limited to a therapist. I try to be somebody you can come to and talk about deep stuff for my friends. With one friend of mine, I mostly talk about deep feelings. It is great to have somebody like her, it’s a different category than therapy. A therapist shouldn’t give you his opinion and rarely shares similar experiences. Sometimes it’s just nice to have someone to talk to in a more symmetric way. For me it’s almost never a burden to listen to the emotions of people I like. I want to hear the deep stuff.
    Sure a friend is not a replacement for therapy, but therapy is also not a replacement for a friend with whom you talk about deep emotions.


  • This hits me hard. I am a cis male and currently trying to get rid of something like toxic masculinity, but as you say it is deeply rooted.

    I acually never strived for the stereotypical man image, I wanted to have an emotional side. Now i know i always just considered “having am emotional side” just as another kind of requirement to be a good man. So i tried listening to others and beeing open myself, talking about emotional things. But only those, that i thougt were accepted. I never talked about my real worries. They always seemed to ridiculous to me. A good emotially healthy man shouldn’t have them or solve them himself. Now it feels pretty dumb in retrospect, but I am no longer letting this feeling stop me from talking about something. In some way I also have the feeling i betrayed other people with a fake personality.

    I know this is not the mistake of feminism. I cannot really say what went wrong to land in this position. I do not even know why i tell this now. In some way, I just want to tell my story and hope someone can relate with it. Secondly i want to say, that the following is not obvious for everyone, at least it was not for me: Beeing emotional is not just some requirement for you, it’s also about having an opportunity to get support for your worries.


  • I just want to say, i loved Dragon’s Egg for this level of detail to the physics. I even did some quick calculations why you want 6 compensator masses not less to reduce the effect of tidal forces. Or the black holes inside the sun, at first i thougt, this is impossible. Then i read some more on it an noticed its well researched.



  • The links are actually only random images from an image search with the terms “solar eclipse through tree leaves” and “iss in front of sun”.

    I think you have in mind, that the rays are not parallel because they have to arrive at different positions. As you say, this is negligible, and it can even be avoided by the tilting of the mirrors. However, the rays start from different parts of the sun, and as the sun is huge, this angle is not so small.

    I’ll try to explain it in more detail, sorry for the wall of text, it got longer than expected. In this case, we can use simplified ray optics and ignore the wave nature of light. This means, the light of the different mirrors or even pieces of mirrors just adds to one another. An important point, even if obvious, is that each point on the mirror surface can only have one orientation. Now we “select” the orientation of this point, we orient it in a way, that it reflects the rays from the center of the sun1 directly on the sun.2 But until now, we have ignored the rays which come from the rim of the sun. These rays start at a different position, namely the sun radius (695700 km). Due to different starting position, the rays have a different angle to arrive at the power plant, arcsin(sun radius / sun-earth-distance), which is 0.27°. Now we already oriented the mirrors parts in a way, that the rays from the center of the sun are reflected onto the satellite, but the rays from the rim of the sun come at an 0.27° differing angle. If the incidence of the ray on a mirror is changed by an angle, the outbound ray is also changed by the same angle. This leads reflected rays leaving in a direction 0.27° offset from the direction to the satellite. Assuming the satellite is at a height of 300 km and directly above, it is 300 km away, the smallest realistic distance. With this angle, it leads to a miss of plant-satellite-distance * sin(angle) leading to 1.4 km. This thought is valid for all points on the rim. Similarly, the rays between the rim and the center land between the satellite and 1.4 km off target. Hence the plant projects an image of the sun onto the satellite with a radius of 1.4 km.

    1 Well they actually do not come directly from the sun, they still come from very close to the surface, but they seem to come from the center of the sun and for rays it is not important how far they have already traveled. We can just assume the sun is a disc.
    2 If we assume the mirror is optimally shaped, we can reflect every ray, which seems to come from the center of the sun, perfectly on the satellite. Such a mirror would be part of an ellipsoid, with focal points at the center of the sun and the center of the satellite. In practice, it would be practically indistinguishable from a paraboloid with the satellite (deviance of 1.5 µm with a guessed plant size of 1 km). This is possible as the rays through the center of the sun falling onto the plant are, as you say, almost parallel.


  • Ich hab den Hinweis auf diese Studie in Wikipedia gelesen, wonach steht:

    Auszug aus Wikipedia

    In einer Pressemitteilung stellte das Forschungsprojekt Life-Eurokite nach der Ausstrahlung des frontal-Berichts klar, „Diese Ergebnisse sind nicht per se auf die aktuelle Debatte um Todesursachen vom Rotmilan in Deutschland übertragbar (auch wenn dies im Beitrag so dargestellt wurde), da die Todesursachen in Europa ungleichmäßig verteilt sind. So treten bspw. Vergiftungen und illegale Abschüsse sowie der Stromschlag an Elektroleitungen in Deutschland wesentlich seltener auf als in anderen europäischen Staaten“ und kommt zum Schluss „Es ist zum derzeitigen Projektstand nicht auszuschließen, dass es in Zukunft zu Verschiebungen bei der Häufigkeit der Todesursachen kommt.“

    Soweit ich mich damit beschäftigt hab ist es nicht so klar wie ein kleines problem es wirklich ist. Deswegen ist es gut wenn weiter an diesen punkten geforscht wird. Ich stimme gern zu, dass das problem wesentlich übertrieben wird in der Gesellschaft. Und dass es den Ausbau der Windkraft nicht verlangsamen darf.
