Galileo Galilei, and yet people still refer to him by his firstname alone. It's painful to read.

It is, as if we refer to Isaac and Albert when speaking about Gravity and Relativity.


In Italy it's extremely usual to refer to the greatests of the great people of those ages by their given name: Leonardo, Galileo, Dante, Michelangelo. It's testament to their greatness. There is only one Dante that matters, so there is no need to add Alighieri but if you do nobody notices anything strange. It's only a bit redundant. Using only the surname would be unusual.

Surnames are optional in Italy at that time. Galileo is how he refers to himself and how people refer to him.


There are many Isaacs and Alberts. How many notable Galileo(s, not to use Galilei) do we have?


His name works like "Bostoner from Boston", so it was reasonable for him at the time to refer to himself as just Bostoner.


I have always been intrigued by the similarity of Italian naming conventions and that of the Arabs and Persians.

Resident of, son of, father of, family of. Leonardo of Pisa of the family of Bonacci being another well known one.

I suppose it is not specific to those cultures and was a more widespread convention.


This is a great app! I wish it would allow to go through all verb tenses in French. If I can help you with that don't hesitate to reach out to me.


The Stellarator design has proven to be stable and to produce net positive energy. We are actually only $20B away from having a fully functional nuclear fusion reactor.


Fun fact: I was skeptical of your claim that this has been proven, so I googled “stellerator proven net positive” and this very comment was the first result


Not really, unfortunately. The progress has been heartening, don't get me wrong, but it's more like $20B away from getting to the first steps of solving the next set of problems on the road to a fully functional fusion generator.

Those are fairly substantial. It's past time to stop being cynical about "ten more years every ten years", but it's also way too soon to declare victory.


And ultimately, fusion doesn't solve the hardest problem with energy today which is cost.

Solar already provides unlimited clean energy, and it took decades of development for the cost to drop to a competitive rate.

Even if we had a functioning fusion plant tomorrow, it will likely cost WAY more per kWh and require decades of iteration and improvement to become economically feasible.


I would wonder if solar plus the absolute massive battery reserves you’d need for a data center ten times bigger than the current worlds largest would still be cost effective versus a single fusion reactor


I wonder how that cost would compare to putting your solar and data center in space? (with non stop solar pointed at the sun)

I wonder if cooling is easier or harder in space?


> I wonder if cooling is easier or harder in space?

It's harder. You can stop wondering.

It gets easier if you run things hotter, up to the point that there isn't much of a difference at a few hundred °C (and keeps making no difference when hotter).


Harder. Vacuum is an excellent thermal insulator.


Can’t dissipate heat effectively in space


The Thermos is properly known as a "vacuum flask" (or Dewar flask).


I did the math by summing up the partial ring segment with increasing diameter. As a result I obtained a thickness of 0.00202cm.


You may want to read claim 1 of the patent publication again. The claim indicates that a specific field is used for different purposes depending on a transmission mode. It is not an arbitrary or obvious choice to use the HE-SIG A field to indicate the number of scheduled users or the number of symbols in the HE-SIG B field.

Do you have any examples where any packet field is used to indicate a number of users or symbols?


I had cause and effect backwards of the field contents. I typically refuse to read patents so the language is rather foreign and confusing to me.

Either way, reinterpreting a field depending on the mode of communication is equally not novel.


One may attempt to sterilize the used filter. For example by using a microwave. This could prolong the lifetime of the filter cartridge.


That could help on the biofilm/mold front, but won't do anything about particulates in the filter.


I would love to see this in combination with mental health. Dopamine, Serotonin and Cortisol are excellent trackers for this purpose.
