Depends. Who are you? Can you write? The most important is the second one. A boring life, well written, can be interesting. Terrible writing is terrible, period.

🔴 🇦🇷 🎥 **Is Milei’s Radical Plan to Save Argentina Working?**
"_After eight months in office, Argentine President Javier Milei has slashed spending on social security, public wages and consumer subsidies. His austerity measures have won praise from former US President Donald Trump and Elon Musk. Milei also remains largely popular at home, with approval ratings above 50%. But painful reforms can only stay popular for so long. To win midterm elections next year and hang on to power, Milei must lift a cobweb of capital controls to restart the slumping economy without fanning inflation further._"

The Bernoulli numbers are defined like this:
x/(1 - e⁻ˣ) = B₀ + B₁x + B₂/2! + B₃/3! + ....
and if you grind them out, you get
B₀ = 1
B₁ = 1/2
B₂ = 1/6
B₃ = 0
B₄ = -1/30
and so on. The pattern is sort of strange.
They're connected to hundreds of interesting things. For example if you want to figure out a sum like
1³ + 2³ + 3³ + ... + 10³
or
1⁸ + 2⁸ + 3⁸ + ... + 1,000,000⁸
you can use a formula that involves Bernoulli numbers. The video here explains it.
But where the hell did this function x/(1 - e⁻ˣ) come from?
If D means derivative:
(Df)(x) = f'(x)
then 1 - e⁻ᴰ is a so-called 'difference operator':
((1 - e⁻ᴰ)f)(x) = f(x) - f(x-1)
which you can show using the Taylor series for f. So D/(1 - e⁻ᴰ) is about derivatives versus differences, and its inverse is about integrals versus sums. This lets you reduce sums like those above to integrals... 𝑖𝑓 you know your Bernoulli numbers!
But x/(1 - e⁻ˣ) also shows up when you compute the expected energy of a quantum harmonic oscillator in thermal equilibrium!
Let's work in units where ℏ = 1. Say we have a quantum harmonic oscillator whose allowed energies are 0, 1, 2, 3, ... etcetera. What is its average or 'expected' energy at temperature T? Let x = 1/T. Then its expected energy is
x/(1 - e⁻ˣ)
So the quantum harmonic oscillator secretly knows about Bernoulli numbers.
What does this fact really mean??? I don't know. I once read a book called Triangle of Thought about a conversation between Alain Connes and two other mathematicians, and he said this fact explained a lot of stuff. But he didn't go into any detail, so I'm left looking for clues.

"_Evans devotes an incisive chapter to each of the rogues’ gallery of Göring, Goebbels, Himmler, von Ribbentrop and to notorious antisemites such as Ley, Streicher and Heydrich. It is however even more interesting to read about lesser figures who portrayed themselves after 1945 as honourable, principled and patriotic and far from being deranged and perverted._"

🔴 💧 **Mapping safe drinking water use in low- and middle-income countries**
_Our results emphasize that access to an improved drinking water source does not always provide safe drinking water as <u>almost half of the LMIC populations (48%) were estimated to be exposed to fecal contamination in their primary drinking water source</u>. Our predictions show that more than half of the populations of Oceania, sub–Saharan Africa, southeastern Asia, and Latin America and the Caribbean may be exposed to contaminated drinking water (fig. S9)._
