The climate change movement: July 28, 1995 to August 14, 2020 RIP

Doubt that you would change the oxidiser/fuel ratio much using a different gas. Way too much volume going through the system in any given second. Once again, I think it's a use what you got handy. Couldn't use monomethyl hydrazine because it even reacts with stainless.

I saw it described as inert and non-toxic.

Maybe it's got something to do with

https://www.britannica.com › science › Avogadros-law
Avogadro's law | Definition, Explanation, & Facts | Britannica
Avogadro's law states that equal volumes of different gases contain an equal number of molecules under the same conditions of temperature and pressure. The specific number of molecules in one gram-mole of a substance is Avogadro's number, or 6.02214076 × 10 23.

They're having to deal with tons of the stuff.

America’s Newest Hero

The story is that the fin had been redesigned prior to the launch; the change will been incorporated into #32, so nos. #30 and #31 may never fly.

Their parting shot is hoping SpaceX has a Dragon capsule standing by in case the Helium problem is out of scope.

2-bit summarizes an MIT research project that claims to have evaporated 4x more water than heat alone can accomplish by using light. This can increase the efficiency of desalination, or introduce efficient cooling methods.

SA is always talking about humanity's unique ability to engineer solutions.

Isaac Asimov: 'The most exciting phrase to hear in science, the one ...
Feb 17, 2024 Isaac Asimov once famously said, "The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'" This quote encapsulates a profound truth about the nature of scientific inquiry and the process of discovery.

I don't think I've been more exhilarated by a space launch ever, and feel like it didn't get much attention. For the first time, I feel confident that the moon will be visited by humans in my lifetime.

Not sure if I heard the commentary correctly, but an end-goal of $5M per launch might have been mentioned. If that could take 100 people up, that's $50k per seat. Then there's accommodation which is an additional cost... if I can spend a couple days in space for ~$500k when I'm 90, I'm doing it. Only 1 fall risk to mitigate up there.

Appreciate Bill's subtle jabs at dysfunctional systems, and nod to the cost of functional ones.

Nothing is ever more than I want to know, with the exception of certain details of how women deliver babies (I've been there, but not looking both times). The most annoying thing is an obituary that doesn't include the cause of death. When I come to my demise, the least someone could do is tell the story, even if it's surprisingly basic.

My engineering mind can't let go of stories that end in mystery. On Starship 3 launch, I was frustrated to not know why stage 1 went out of control and crashed, and then stage 2 tumbled about and burned up. Some people can just say to themselves "well that's the end of that", and go to sleep, which is most people fortunately.

So what do you make of the Longyou caverns?

Here's a new example, a quarry not far from Toky:
Mt. Nokogiri: Ancient Quarry Mountain excavated by prehistoric machines or hand tools?

It exhibits finely finished inside upper corners like Puma Punku.

Anyone see the SpaceX launch today?

The 'science' of non-linear global warming has ALWAYS been a permanent fixture of the data submitted to the IPCC, since before there was such a thing as an IPCC ( you might watch the 'Unchained Goddess' from the 1950s ).
The scientists who submit this data, every contribution cycle, continue to have no control over what the IPCC actually publishes in it's ongoing reports.
If we stop 'ALL' greenhouse gas emissions immediately, we'll still blow past the 1.5-C target.

I believe that is the most probable outcome as well. There's no IPCC projections showing that to lead to Venus warming though. All scientific opinions on what the ideal temperature would be are specific to their area of expertise. For instance, an entomologist will have a different answer for the ideal global temperature based on what they know of malaria-carrying mosquito habitats. That opinion ignores a holistic view.

I'm always asking, and never getting an answer to my question;

Considering that humanity has flourished tremendously due to continual warming from the depths of the current ice age, at what point in time is the ideal warmth level for human flourishing?

So far, every measure of human flourishing suggests we haven't surpassed the ideal warmth level yet.
