Not meaningful? Or is it.

In fact it also reminds me of DOGE mixing up inefficiency and redundancy.

This sounds what happened to Deutsche Bahn. You could set your watch to the train arrivals, then they optimized for efficiency and created something that the article calls brittle. It is still a mess.

Not sure it works as well as authors hope. I bought one of your books because we read your long running week in Tory series, so you provided value up front. I never felt like buying a book because an author plugs it in a post.

Thanks. A fair chunk of my BlueSky discover feed is authors plugging their books.

Did you watch my entry? What do you think? It is getting a middling score, which I am ok with. As you said, it is competing against strong entries. However, the SoME comments contain some strange criticisms...

SoME β€” Create and discover new math content The Summer of Math Exposition is an annual competition to foster the creation of excellent math content online.

SoME4 peer review is open!

Skimming over the entries list, I'm really impressed by the quality and work everyone put in their entries. We've got some gems in there.

Time to review, vote and spread the word!

Posted my submission. Crikey, that was more work than expected. I didn't want to preach to the converted, so as a topic I picked "motivation"

Thank you for this clear answer. This sets fundamental physics apart from every other science, that strive to answer the β€œwhy” questions

Including you? Can you explain? I genuinely have trouble understanding. Isn’t what it all means the most important part?

So Copenhagen is uncontroversial and universally accepted?

@fred-crozatier.dev I am having real trouble registering for SoME. It alternatingly complains that Profile exists or claims that there is a Network error.

Number 1 is my gut feel. We listen to radio for decades and don't hear chatter, so clearly radio is not the preferred medium for interstellar communication. Maybe there is something better than electromagnetism, maybe weaker and difficult to harness, but dropping off linearly with distance, ...
