    There are plenty of things that can cause fires that are not oxygen, and don’t contain oxygen.

    The halogens, Fluorine and Chlorine in particular, are powerful oxidizing agents on their own and can produce flames in the same manner as common flames.

    Here’s a report on the spectra of flames produced by combustion in a Fluorine atmosphere (PDF warning).


  • paying a peasant to work

    Peasants (serfs) were not paid. They were bound to the land they worked, and were given a fraction of the harvest they produced. The rest was property of the Lord who’s title controlled the land.

    There was a (very small) artisan class where the concept of payment existed, though often it was payment-in-kind - smith the plow for my oxen and I’ll give you some food after the harvest. Money was rarely encountered for the vast majority of people.


  • Explaining what happens in a neural net is trivial. All they do is approximate (generally) nonlinear functions with a long series of multiplications and some rectification operations.

    That isn’t the hard part, you can track all of the math at each step.

    The hard part is stating a simple explanation for the semantic meaning of each operation.

    When a human solves a problem, we like to think that it occurs in discrete steps with simple goals: “First I will draw a diagram and put in the known information, then I will write the governing equations, then simplify them for the physics of the problem”, and so on.

    Neural nets don’t appear to solve problems that way, each atomic operation does not have that semantic meaning. That is the root of all the reporting about how they are such ‘black boxes’ and researchers ‘don’t understand’ how they work.


  • Not quite. First, the vast majority of Iraqi equipment was Soviet, and the vast majority of the stuff that wasn’t Soviet was French.

    French contractors even built the air defense network and control center.

    Certainly there are tensions in Iraq as a result of it coming in to being as a constructed nation - nowhere did I say otherwise. However that doesn’t justify a war of aggression against a neighboring country.

    Further, Iraq’s casus belli had nothing to do with having a potential ‘claim’ to Kuwait’s land. Kuwait sovereignty pre-dates by centuries. The real reason was Kuwait’s refusal to write off Iraqi debt and refusal to lower its oil product (it was producing above its OPEC quota - depressing prices and hurting Iraq’s exports).

    It is true that Saddam thought the West was using OPEC and Kuwait to undermine Iraq. That may be true. Putin thinks the West is using Ukraine to undermine him - so should we stop supporting Ukraine and let Russia annex it?



    1. Hans has admitted to cheating in the past
    2. Hans played a near-perfect game as black against the best player in the world who hadn’t lost as white in years
    3. Hans made some suspiciously good moves quickly, without much time passing
    4. Magnus played a very rare opening that Hans was somehow able to perfectly respond to without skipping a beat

    From these, many people think he cheated. The vibrating butt plug is unlikely, but what is more likely is that Magnus’ prep got leaked and Hans was able to hyper-prepare for a specific line of play.




  • Interesting how you ignore how the US did not recognize the goverment installed by the people of korea (PRK)

    The brief existence of the PRK has essentially no bearing on the civil war. It existed less than a year, and was dismantled in both the South and the North by the actions of the US and Soviet Union.

    Neither power cared to entertain what the people of Korea wanted in the Post-War period.

    I wonder what half-truth or outright lie y’all will respond with next to paint the US and SK as Satan next to the Angelic Soviet Union and DPRK.

    No power were the ‘good guys’. None had the moral high ground. All deserve blame for what happened. The history of the period is one of tragedy and ambition.

    None of that changes the fact that North Korea, backed by the Soviets and later China, started the shooting war by invading the South.










  • Believe it or not, what you swallow has almost nothing to do with your weight. The only place the body absorbs energy from food is in the intestines, and the brain controls that process.

    The digestive tract is a tube, open at both ends, through which food passes. The process of extracting energy from that food is complex and highly tunable: the brain controls the production and secretion of hundreds of enzymes and other chemicals, as well as the physical action of the muscles lining the tube.

    The ‘basic physics’ here begins at the intestinal wall, not the mouth.
