What exactly is a tokamak? 🤔
It's a machine designed to harness fusion, the process that powers the stars. At its core: a doughnut-shaped vacuum chamber where hydrogen becomes plasma at 150 million °C, ten times hotter than the Sun's core, confined by massive magnetic coils.
ITER, in France, will be the largest ever built.

This morning I am thinking about all of the scientific terminology related to fusion reactors I added to my personal dictionaries lately and about properly spelling "enshittification" with two t's rather than one.

Because I'm a bit of a cybersecurity wonk I often use task specific browses and accounts, some of them from fully walled off disposable one time use virtual machines, and I get to see the very weird assumptions the fiends at the monopolies make based on limited information provided to their ubiquitous surveillance systems.

While I do not need a vast array of personal spectroscopic lab equipment starting at the low, low, discount act-now price of $25,000 and going up from there, I do have a YouTube/Google account that runs to ads hawking that sort of equipment and very nice high resolution digital microscopes, which granted might be very useful kitchen accessories given that the food supply is no longer inspected or safe, but are quite out of my financial reach no matter how cool it would be to examine my salads before they send me to the ER. The people at the Googlag seem to believe I may have access to an institutional equipment budget due to the materials science reading I do and the physics videos I watch.

From time to time I reinforce their erroneous assumptions by doing price comparisons for gas spectrum analyzers and laboratory safety equipment that might be handy around the house.

💁🏻‍♀️ TIL: 🧵🌐 The hairy ball #theorem says you can’t comb a #sphere smooth without a cowlick somewhere.

The same rule explains why #Earth always has a #cyclone spinning, why #fusion reactors use #doughnut shapes, and why omnidirectional antennas can’t exist. #Wind patterns over the #Arctic and #Antarctic circles illustrate the proof.
