My experience with MathOverflow was funny, the first time I posted a question it was almost immediatly downvoted and criticized by the moderators. Later the same day, I was surprised when my question was answered by Terence Tao, then the moderators quickly changed their opinion and people started to upvote the question.
At first glance I was trying to figure out what this is about but, so far nothing. It's "like caniuse but for email content", ok but, what is caniuse? I don't know if it is worth but, before launching something new, I wish everyone consider to publish a brief section to explain to the average person what this is about.
Yes, I like this explanation, when that phenomenon happened in our house I thought one of our neighbours was dumb because he just put a blanket over the collector on the roof, as he said, "to keep it warm". But now I think he was right. Now, I don't know if this exists but it would be nice if there was a kind of glass that let radiation pass only to one side and not the other way, a kind of "valve", this could solve the problem of water frozing from radiation in our solar heating.
Here in Brazil we use a system with copper pipes in an insulated "box" to heat water during the day using this energy from the sun. A couple of years ago, in a cold winter day with a minimum of 5 degrees (celsius), just after the sunrise the water froze, broke the pipes and the glass above it. I couldn't understand what happened because the ambient temperature was above freezing point, maybe it was something like this effect?
I like footnotes, or in this case maybe we should call "endnotes". David Foster Wallace was known to use them a lot, sometimes he would put footnotes in footnotes.
I don't know about law exam, but Brazil has more undergraduate courses in law than all the rest of the world combined, naturally this comes with a lot of shit univesities and that means a lot of people with a law degree but don't work in the field.
Without a Raspberry Pi, at least you can use the wolfram engine for free [0] and integrate with your applications, although without all the benefits of the wolfram notebooks environment.
I get recommendations in scholar.google.com based on my profile and sometimes browse arxiv.org to see the latest submissions. Also, I can say that https://www.quantamagazine.org/ is very nice. Other than that, I just follow my favorite scientists through their personal blogs or social media.
This reminds me of that old joke "In the fall of 1972 President Nixon announced that the rate of increase of inflation was decreasing. This was the first time a sitting president used the third derivative to advance his case for reelection."

I am not a morning person and sometimes I think about it, is it possible that my natural cycle is x hours of sleep and y hours awake and that x + y is not 24? I think this is my case because every now and then I can wake up early only to loose track, then go back to stay up longer in the night and wake up late again.
