mef51··on Epidurals are a miracle technology
I've heard a few times now that giving birth while lying on the back is a relatively modern invention and that for most of history women adopted squatting or leaning forward positions.[1] And that the back position is actually much more painful. How much does laying on the back increase the pain to the point where an epidural is necessary? Is it still necessary in the other positions?

disclaimer: I know nothing about this

mef51··on Bitchat for Gaza – messaging without internet
Acting like the dominant political stream in Israel has not been interested in occupying Gaza since at least 1967 to this day is a bald faced and shameless misdirection.
mef51··on Bitchat for Gaza – messaging without internet
The colonization of Gaza and the West Bank is entirely driven by western interests and ideology. Namely Zionism[1]

mef51··on Criticisms of “The Body Keeps the Score”
Trauma to me means there are ways of responding to painful experiences that can keep you in that painful state for a very long time, and/or make things worse. I recognize that simple fact from my own experiences. In that lens, its helpful to reflect on your responses to painful experiences to stop them from developing into long term traumas. Maybe that's why this book, or at least the title, seems to resonate with people. (I haven't read it)

...But it's also good to know the author of the book was wildly mis-citing things

mef51··on How Israeli actions caused famine in Gaza, visualized
From the article: "An internal US government review found no evidence of widespread theft by Hamas of US-funded humanitarian aid in Gaza." Other reporting supports this.

So what is going on is that the IDF are lying to justify their genocide. There is a massive propaganda machine at work to muddy the waters.

mef51··on How Israeli actions caused famine in Gaza, visualized
Israel blocks the entry of Plumpy Nut into Gaza, a peanut-butter like paste meant for treating severe acute malnutrition. They say it is a luxury item Hamas might steal.[1] The amount of evidence Israel is committing genocide is embarrassing.

mef51··on Terence Tao: The role of small organizations in society has shrunk significantly
I'm not sure I entirely agree with the framing, despite agreeing with many of the points raised. I think it's relevant to recognize that large organizations often become large by consuming smaller organizations. And that they consume smaller organizations precisely because they offer something like purpose and meaning, and other emotional/spiritual needs. When there are no more smaller organizations to consume, the larger organizations fracture out of an absence of these necessities. The division of 'small' and 'large' organizations is maybe relevant in today's economic structure but it does not feel absolute or permanent. Anyway, this well highlights the importance of genuine connections and activities at the individual level.

I read this letter for the first time many years ago when I was in my physics undergrad and thinking about starting grad school. It still crosses my mind pretty often as a postdoc.
mef51··on 4-7-8 Breathing
Plum Village (a Buddhist community founded by Thich Nhat Hanh) has a free app with hours and hours of different kinds of breathing and other types of meditation. They also upload meditations regularly on their youtube.

This web page also has some good resources and breathing meditations. https://plumvillage.org/mindfulness/mindfulness-practice

mef51··on Leaked data reveals Israeli govt campaign to remove pro-Palestine posts on Meta
"The civilians should be evacuated." They don't want to leave and Israel uses these "evacuations" to make sure Palestinians never return, as they did in 1948, 1967, etc[1][2]. This is whitewashing genocide and is an extremely violent view, packaged in reasonable sounding words. Israel has a long documented history of using terrorism to build its state. If you truly oppose terrorism I recommend starting with the books I've sourced.

The HRW report[1] goes into details, at least on the 1050 takedowns they documented

> A Human Rights Watch (HRW) report investigating Meta’s moderation of pro-Palestine content post-October 7th found that, of 1,050 posts HRW documented as taken-down or suppressed on Facebook or Instagram, 1,049 involved peaceful content in support of Palestine, while just one post was content in support of Israel."

mef51··on On YouTube’s recommendation system
If you think of the Youtube recommendation system as a person, you would immediately understand how creepily this person is behaving by trying way too hard to get what it wants from you (ad clicks) under the guise of caring about you or your interests.

Just because I click on a video and watch it entirely doesn't mean I want to see more like it, and it doesn't mean it was healthy for me to watch, it could have just been a distraction. But now this system will latch on to my need for distraction and keep nagging me with stuff in the long term that is ultimately harmful to me.

I don't believe recommendation systems like this can ever really understand people well enough where a person can walk away and feel healthy about it. But they are great at generating money and that is why they exist. I can see and appreciate the amount of effort that is trying to make these systems better but they are fundamentally flawed and limited.

mef51··on Instagram, Twitter blame glitches for deleting Palestinian posts
It's the first sentence:

>> According to a 2017 survey by University of Haifa professor Sammy Smooha, 16% of the Arab population prefers the term "Israeli Arab", while the largest and fastest growing proportion prefers "Palestinian in Israel", and 17% prefer "Palestinian Arab"

I promise you Arab Israelis mostly identify as Palestinian

mef51··on Taking sex differences in personality seriously (2019)
>> Only by facing reality as clearly as possible can we even begin to make changes that will have a real positive impact on everyone.

While I agree with this sentiment and appreciate all the research shared, I'm not sure a flood of scientific studies is going to be clearly accessible to the significant segment of the general public that doesn't have the training or time to process this information. The quickest and simplest way to "face reality" is not to drown people with long detailed academic studies but to engage with people based on their experiences and needs. I don't need to read a scientific article about what females want on average in a relationship to know that my female partner might be needing more emotional connection, I can just ask her, or encourage her to share that with me. I also agree with the author that people can make rigid assumptions based on gender that are not factual (such as the assumption that there are no personality differences across the sexes); but do the public and the people making policies at the institutional level need to absorb a series of lengthy academic studies to consider the possibility that their assumptions might be wrong? Do we really have hope that this is how things happen? It is simpler to be conscious of what is fact and what is assumption in your own mind and ensure that you leave room for the uncertainty, and to ask this of people who have power.

mef51··on What does any of this have to do with physics? (2016)
You can have as high of an ideal as you want about physics, quantum gravity, Einstein, Feynman, and hard work, but you should at least be aware when you start to abuse yourself in the name of this ideal. Fifteen hour days in the library? Reading paper after paper while ignoring the feeling you don't have a direction? These are moments where self-empathy can go a long way. And the more you dig into your ideals the less of a pedestal you put them on, and you can see them more clearly as they really are, and as human. Einstein was very close-minded about physics in his late career. Feynman was brilliant but also said a lot of other things other than "Shut up and calculate", which, by the way, the context of which is "eventually you just have to shut up an calculate" (from one of his books I believe). Quantum gravity isn't the only deep mystery in physics. And why does glory always seem to the main motivation for pursuing quantum gravity?

> "But in the end, I never knew what I was looking for and I didn’t find it."

To me it felt like you were looking for meaning and purpose in quantum gravity and its (mis-)characterization as the Grail, or at least in the process of working on quantum gravity. But it seemed like it was difficult to admit to yourself that it wasn't working, which ultimately makes the going even tougher.

I'm in a physics phd right now and I see this disconnect in myself and in other academics a lot.
