Realistically I don't see how this could be submitted to a journal as-is. I'm sure you could take this material and write a couple papers out of it, but right now this is a 60 page word document with commentary on a variety of topics from memory market economics to quantum computing. It's full of self-congratulatory language like "The transition is not an incremental improvement within the existing paradigm; it obsol…

The paper has been under peer review at Physica Scripta (IOP) since March 25. The reviewers will decide what stays and what's trimmed. You're reading a preprint, not the final version. The tone in the architecture sections reflects the scope of the claim — reviewers may ask me to moderate it, and I will. The core physics (Sections 2–3) is standard computational chemistry: DFT, transition state optimization, CCSD(T) v…

Just remember Watson and Crick's famously humble line in their 1953 Nature paper: "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material."

Big discoveries will speak for themselves.

Yeah, I've been baited by "breakthroughs" in storage technology for almost 40 years at this point [1]. I'll believe it when it's in Best Buy. Battery "breakthroughs" have really taken up the mantle of headline-grabbing research fund-raising articles so it's nice to see a throwback to the OG: storage.

I mean battery breakthroughs are real though? BYD is now demoing 0-80% in 5 mins on production vehicles in China.

The price of the 50kwh unit I had put into my house was very low.

Sodium ion is ramping up too but is commercially available. That straight wasn't possible a few years ago till the electrode breakthroughs.

Is there a reason you went for 3 PhDs? Especially since they're all in STEM? To me it's a red flag because the point of a PhD is to learn to do research, you don't need to get another one to move between fields (especially within STEM), just need to do research with people in those fields and gain experience.

Some people actually enjoy studying and learning in these spaces. Does everything have to be optimized for?

3 PhDs is quite some dedication to science, given that a PhD student life is neither that of plenty nor leisure.

Some people do not need to worry about material possessions as much as some others because of the random birth wealth lottery. Then they can pursue interests in less goal driven ways than it would otherwise seem wise

Do you have any pointers on said 50kWh battery? Asking for a friend.

What's so special about specifically the PhD student experience that isn't accessible once you have the PhD?

My experience has been that research became much more fulfilling after finishing my PhD. I got more research independence, the level of work I was expected to do increased, and as a bonus, my salary almost tripled. It was like having the world open up, and starting to really experience being a scientist without my PI protecting me.

I was curious about their decisions because if you're taking on the opportunity cost of a PhD, it's probably because you enjoy research, but if you enjoy research, you wouldn't keep going back to the starting point. So, without additional context, it seemed like they just wanted the credentials.

I think it was also worth asking because universities often want to know why you want another PhD, since from their perspective, spending that funding on someone with no PhD potentially creates a new researcher (vs spending it on an existing researcher). So, if they managed to get into a PhD program again, they probably had a good reason.

Their response about different countries is an explanation (especially from an immigration angle), it's not like I'm asking them to lay out all their personal circumstances behind the decision in detail.

In many European counties it's easily feasible to just study all your life while working ~20 hours / week. I won no lottery but had no issue spending a decade of my life pursuing interests at universities while working 20-30 / hours a week in a comfortable software dev job.

If I'm paying for "free" education with my tax euros, I might as well use it.
