@freemo Makes flames with free gases. Water's funny stuff though, might be about the phase change allowing easier dissociation.

@freemo Yes, it is curious how steam seems to work better than water. I suspect it's more about heat transfer than anything else.

@freemo There are not many that you could get to that temp without melting, including steel. It's when we use steam it happens most.

@freemo Usually needs to be a little more yellow than red, but you do see in when working steel.

Scottish physicist C.T.R. Wilson was born #OTD in 1869. He won the Nobel Prize in Physics for his invention of the cloud chamber. The inspiration for his prize-winning work came in the mountains of Scotland, where he served as a meteorological observer. He decided to try to reproduce cloud formation in the laboratory. In 1895 he produced his 1st cloud chamber, which supersaturates the air by expanding and cooling it. He realized that the device’s potential went far beyond understanding weather.

Israel claims there is not a policy to forcibly expel Palestinians in Gaza, but direct testimonies from people arriving in Rafah reveal there is a ethnic cleansing campaign taking place around Gaza City.

As the sun rises we're getting a clearer image of what Israel bombed last night in Rafah.

Tents. Tents full of people and crops.

@sciencebase It is now roosting in my loft. Has its boot on too.

Airliners filled with flowers zip around the globe every day. Chrysanthemums from Colombia dash to Japan; roses from Kenya end up in Britain; carnations from Ecuador jet to Russia. Nearly all imported cut flowers go through the same emissions-intensive journey — climate-controlled greenhouses, refrigerated trucks and a long, chilled flight. Fresh flowers are a $34 billion global industry with a massive carbon footprint

"Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer."

Critique of Pure Reason (1781; 1787), Preface, A vii

~Immanuel Kant (22 April 1724 – 12 February 1804)

"Any AI system is defined by its reliance on the use of data from the past to make decisions about the future.

"But the government signaled it is concerned that the technology’s use by insurers is allowing them to bend the future to their own benefit."

Hey uh. So I'm kinda stuck in a place where I've closed myself off some, don't have a support group or family as such.

How do you ... make something like that? Like, I don't even have someone I trust to call if I need a ride home.

I'd... especially like some advice from people who've tried to make it in cultures that aren't theirs. I don't have a culture, I got brought up between three different countries and none of them are "mine" and none really accept me as "theirs". Some times that's fine, other times, especially when it combines with other aspects of identity that are also deemed a problem (ADHD, trauma, gender identity, sexuality), it's the worst thing in the world and so, so isolating.

Boosts are appreciated. I'm not good at reaching out, so every bit helps.

American writer Kate Chopin, best known for her stories about the inner lives of sensitive, daring women was born #OTD in 1850. Her short stories were well received in the 1890s and were published by some of America’s most prestigious magazines—Vogue, the Atlantic Monthly, Harper’s Young People, the Youth’s Companion, and the Century. Her early novel At Fault was not much noticed, but The Awakening was widely condemned.

Following the latest on the new eruption on Rekyjanes that started this morning in Iceland.

The lava flow crossed Grindavíkurvegur Road, and primary north-south corridor, and has severed the hot water pipeline that runs from the geothermal plant and provides service to the rest of peninsula.

Areas without hot water include Keflavik International Airport and nearby communities.

RAPID records 20 years of AMOC observations!
But how the Atlantic got its observation system is a mystery to many 🧐. In his latest paper, #MPIM_scientist Jochem Marotzke narrates the history and reveals the ideas that led to the foundation of the observing system. He explains the achievements of RAPID so far and shares his proposal for the future to understand AMOC variability.

Check out this article on the interesting paper: mpimet.mpg.de/en/communication

My new Coppola Comment post, on Gaza's tunnel economy. How a network of tunnels enabled Gaza to withstand a siege and brought about a remarkable, if short-lived, economic recovery.

Margaret Bryan (1759-1836(?)) was an English natural philosopher and educator, and the author of standard scientific textbooks.

Her first known work was Compendious System of Astronomy (1797), collecting her lectures on astronomy. She later published Lectures on Natural Philosophy (1806), a textbook on the fundamentals of physics and astronomy, and an Astronomical and Geographical Class Book for Schools, a thin octavo, in 1815. via @wikipedia
