Summary

A massive Ukrainian drone strike targeted Russian oil refineries and infrastructure, including Moscow’s largest refinery, which supplies 50% of the city’s fuel.

The attack also hit the Druzhba pipeline control station, halting Russian oil exports to Hungary. With over 337 drones striking multiple regions, the operation exploited gaps in Russia’s air defenses.

Hungary, heavily reliant on Russian energy, called the pipeline attack a threat to its sovereignty.

Analysts suggest continued strikes could pressure Russia’s economy and energy dominance, potentially influencing ceasefire negotiations.

I'm of the mind that the Orange Imbecile intends to start a war, any war, to justify him staying on as president beyond his second term. If a civil war doesn't happen within 3 months of the start of the next presidential election cycle I fully expect him to attempt to invade us. Whether his military allows it or not is anyone's guess but AFAIK he has already begun emptying the top brass of any dissenters so....

Canada contributed another 50 million Canadian dollars ($34.8 million) to the Ukraine Energy Support Fund, Ukraine's Energy Ministry said on March 14.

Days prior, Ukraine received the first tranche of a loan of $1.7 billion covered by frozen Russian assets from Canada, the Ukrainian Finance Ministry announced on March 13.

HOLLAND, Mich. (AP) — One after another, callers on a telephone town hall with U.S. Rep. Bill Huizenga pressed the Michigan Republican about possible cuts to Social Security. Among them was a retired teacher and coach from West Michigan who said he and his wife, both with disabilities, have struggled to access their benefits.

 

BELGRADE, Serbia (AP) — At least 100,000 people descended on Belgrade on Saturday for a mass rally seen as a culmination of months-long protests against Serbia’s populist President Aleksandar Vucic and his government.

Large crowds of flag-waving protesters clogged the downtown area of the capital despite occasional rain, with people hardly able to move and many stuck hundreds of meters away from the planned protest venue.

Electric car buyers don’t like right-wing politics. This means Elon Musk’s position at Tesla is very vulnerable and susceptible to economic pressure.

Explain to me how lab statistics would help? Then explain how you could generate useful statistics using the extremely non-standardized settings of every unique household in the world?

Now that the absurdity of wanting statistics is set aside... Microwave caused superheating of water is a well studied and understood phenomenon. There are things that reduce the likelihood, sure: air bubbles created by modern low-flow taps, general impurity of tap water, and scratches in used containers all provide nucleation points and reduce the likelihood of superheating.

All it takes is jossling a new mug so the air bubbles all float out, with a particularly clean supply of city water (or filtered is a common culprit) and that thing you've been doing for years blows up in your face at 105^o^C.

Because technically the steam is dissolved in the water above its saturation point, right? If the gas were (say) CO2 instead of steam, wouldn’t “supersaturated” be the correct term?

If the gas were CO~2~ instead of steam, CO~2~ would be the solute, and water the solvent. In that case the term supersaturated would make sense because the solvent contains more solute than it can handle under normal conditions. The steam is not disolved in the water. The microwaved water is unable to form steam in the first place due to a lack of available nucleation sites.

I thought superheating referred to heating water over 100º by pressurizing it

That isn't superheating. The boiling point of a given substance naturally varies with pressure. Liquid water at 200^o^C while pressurized sufficiently isn't superheated. It is just hotter than you expect it to be. That technique can be used to superheat something like water if heated over it's atmospheric boiling temperature while pressurized and then lowering the pressure without agitating it.

That's not what is happening. If you drop a bag into water the whole bag gets wet and seals the air inside causing it to float.

Slowly lower the bag into the water so the air can escape through the dry top and it'll sink.

Thx Tips. Waiting 15 seconds is no guarantee the water isn't superheated. If you actually want to ensure microwaved water won't erupt put a wooden toothpick or spoon in it while nuking.

It is not simply 'just another method to heat water'. There is a significant difference between microwaving and kettle/stovetop. Microwaving risks superheating resulting in flash boiling causing an explosion of steam and boiling water. This is also why microwaved water has foam appear when inserting anything into it. Bubbles that 'should' have formed didn't and are now doing so at the nucleation points whatever you inserted provided.

That foam, while an indication the water was close to erupting, is otherwise harmless but ruins the tea/coffee for me and I'm sure others too.

superheated, not supersaturated.
