  • I bought an E-Bike, the impulsive bit was not getting a normal bike.

    I kinda just figured it would be fun, and probably useful for some longer trips through the city. It ended up being one of the most empowering things I’ve ever owned, I have a pretty nasty health condition with lots of really bad fatigue and I live in a hilly area. I was able to look after myself to a whole new level, it was in almost every way a mobility aid for me, it made it possible for me to get supplies and meds on bad days it was a game changer.

    Anyway it got stolen a couple of weeks ago so that’s cool


  • I joined a climate activism group in my local area, frankly it’s the best possible way to deal with it. You can make a difference, the messaging we get is often intended to make us feel powerless to keep people from protesting, but it’s actually one of the most empowering ways to deal with it. Being with a group of passionate people amplifies your ability to effect change, and given how broken many of our governments are, it’s necessary. The biggest thing stopping us from forcing big changes is our lack of numbers, solidarity is strength.

    It certainly beats sitting around feeling angry and stressed.





  • Nah, I never even started a PhD mostly due to financial circumstances. But I’ve since realised I kinda hated academia because of untreated ADHD lol. I may go back to it one day after I’ve got treatment sorted but I really doubt it, I found my passion in music instead.

    I’ll try and ELI5 haha. Think of a black hole like a battery, stuff falls in to charge it and then it discharges by tickling empty space into creating particles. The problem is that the particles it creates seem to be random, which means it acts like a big delete button for the stuff that fell inside. Due to quantum stuff, this shouldn’t be possible, so some process could exist to encode the information about the original stuff onto the particles that leave the black hole. Importantly this doesn’t actually mean the particles that leave have to be the same as what fell in, you just need to able to look at them and then reconstruct it. Kinda like if you scrambled a book in a way which makes it look random, but is actually a secret code that still has the whole story contained inside.

    My research was to look for that information being written on the particles leaving the black hole, basically by comparing how space and time outside the black hole changes over time and seeing what it does to the tickling.


  • A really painful type of coordinate transformation I once had to develop to try and shed some insight on Hawking radiation near black holes.

    Unfortunately the results were fucking ugly and I gave up trying to understand them, largely due to the fact that except under very specific circumstances they’re basically impossible to calculate (you get something similar to divide by zero errors).

    Nice case:

    Not nice case:

    There was a ton more related stuff I could have spent a PhD working on, but life didn’t really allow it (and frankly I’m okay with that, I’m actually doing enjoyable stuff for the first time in my life instead of fighting my brain).




  • I am trans and I can say I’ve never felt like I was in the wrong body, I think most of the time that’s just a relatively flawed way to describe an experience that can’t truely be understood unless you’ve experienced it.

    Of course, no one has the same experience with these things and it’s entirely valid if everyone else does feel that way. For me it’s mostly just been that something felt like it was missing, and I fixed that when I began to transition. The main thing was how much happier the internal changes made me, estrogen changes how you experience emotions and being out to my family had a similar effect.

    When it comes to “signs” the biggest was just being envious of people who had the freedom to express differently than me. I can confirm that it’s a gradual realisation, though honestly most of that was overcoming shame and internalised transphobia.
