Half truth.

A stronger FM signal will almost completely block a weaker FM signal; this is related to the "capture ratio" specification sometimes seen on FM tuners.

With AM, the audio from 2 signals at the same carrier frequency will be proportional to each of the signals' received sidebands' strengths. Much like listening to 2 people talking at the same time.

With digital, it's complicated.

Comment Re:Healthcare should not be a profit center (Score -1) 236

In the U.S., most schools are government schools, not free market (capitalist) schools.

Where I live, 60% of state + local taxes go to schools; that can't be anything else but shockingly wasteful. Much of that waste goes to paying for individual (or multiple) tutors for children who are brain-damaged, children who will never be able to contribute to society. It's a sad situation, but tutoring children who can't learn is not a solution.

Most schools in the U.S. are heavily influenced if not outright controlled by teacher's unions, and these (left-wing) unions are pushing extremist fads and long-existing anti-capitalist propaganda. This is not a failure of capitalism.

Comment Well, most of it... (Score 1) 26

Anything that goes slow enough to be captured into an orbit will eventually spiral inwards.

Well, most of it (when we're talking matter not already in another black hole). Ordinary stuff orbiting near a black hole gets torn apart by the enormous tides and forms a disk-like structure similar to a gas giant's rings. Interactions among it and with the black hole's magnetic and gravitic fields can eject a bit of it in a pair of jets out along the axis of the disk, powered apparently by the rest of the stuff falling in.

These two black holes wouldn't stick to each other, but start swirling around each other and eventually merge together.

This is partly because of friction with and among other stuff in orbit around the black holes in their "accretion disks". (Black holes experience friction by eating the stuff in the other hole's disk of debris, with the momentum of the black-hole-plus-dinner thus being different from the black-hole-before-dinner.)

It's also partly because the rapid acceleration of things passing near a black hole or orbiting it causes the emission of gravity waves to be strong enough that it carries off substantial energy. (In less extreme environments, like suns and planets, the waves are not detectable by current instruments. In the case of two black holes,orbiting each other, they're detectable from across pretty much the whole universe.) This loss of energy amounts to "friction" that eventually causes co-orbiting pairs of black holes to spiral in and combine.

Comment Re:FDA was wrong on this (Score -1) 350

The FDA advice shown on this slashdot page appears to have been written by someone either hysterically angry or drunk. I am not saying the advice was good or bad. I'm saying that it was written unprofessionally and childishly, containing neither citations nor rational argumentation.

Comment Reminds me of "Jan 6 insurrection" guilty pleas (Score 2) 94

This reminds me of the sentencing of the "January 6 insurrection" guilty pleas. As I (a non-lawyer) understand it...

Regardless of whether you consider it an insurrection or a protest march petitioning the government for redress of grievances...

In the wake of the events, the fed busted a bunch of the participants and left them rotting in prison for months (over a year), with no end in sight. In many cases this left families with no breadwinner, enormous legal costs, and expectations of losing all their property as part of some eventual conviction.

Then the prosecutors offered some of the defendants a plea deal; Plead guilty to a misdemeanor or short-sentence felony and we'll drop any other charges.

Rule of thumb: a misdemeanor generally is a crime with a max sentence of no more than a year in prison, a felony more than a year - which is why you see "year and a day" max sentences on some crimes. An accused person already in prison for over the max sentence would expect that accepting the deal would result in immediate release with "credit for time served" (and others near the max might expect release much sooner). So some of them went for it.

Came the sentencing some judges applied a two-year sentence enhancements for "substantial interference with the 'administration of justice.'" OOPS! No release for you.

I'd expect them to pull the same sort of thing on Assange if he were foolish enough to plead guilty to anything, no matter how minor.

(By the way: This particular form of the practice, as used on the Jan6 participants, was just recently struck down. But the decision was based on Congress' certification of the presidential election not qualifying as "administration of justice.'" So this wouldn't apply to whatever enhancement trick they might pull on Julian.

Comment Re:I heard pregnant women are (Score 2) 29

I don't know what you heard, but baby cells can only stay baby cells, they can't become mommy cells,

Sez who?

There's been evidence for some time that post-pregnancy mothers often have clones of stem cells derived from the previous foetus. Sure such a clone would likely start out with its epigenitc programming set for whatever function it had in the baby's development (unless, say, some error in its differentiation is what led to it migrating to the woman's body to set up shop). But once established on the mother's side of the placental barrier, and especially after the birth, the stem cell clone can be expected to continue to run its program under direction of the growth factors in the mother's blood.

That amounts to a transplant of younger stem cells which could be expected to produce differentiated cells for tissue growth and replacemtnt,, with the aging clock set farther back and with some genes from the father to provide "hybrid vigor", filling in for defective genes in the mother's genome or adding variant versions of molecular pathways.

Scott Adams claims that there will never be full AI because as soon as it contradicts a closely held belief, we will destroy it.

His argument has several flaws: 1.) Who is "we"? 2.) Not all creators of an AI would necessarily want to destroy their AI. 3.) There will not be just one AI. True intelligences often disagree, so will AIs. 4.) As computer power increases and algorithms gain in sophistication, AI programs will be so common that most people will be able to have an AI on their personal computer. Having a million different AIs on a billion discrete computers makes the general destruction of AI nearly impossible.

The main difference between skim and whole milk is the saturated fat content. High saturated fat intake is a risk factor for heart disease in adults. Skim milk has almost no unsaturated fats, but whole milk has so little that it's not a significant source. Other nutrients don't vary much between skim and whole. Generally speaking, for adults, skim or low fat milk is better than whole milk.
