    A tool will be dropped in a manner to cause the most damage.

    If you hit something hard enough, it will fall over.

    Don't forget Maxwell's Equations:

    If it doesn't work, turn it on.

    If it still doesn't work, plug it in.

    Among all the boring tech, some actual science.

    As Troy and Abed would say, cool. Coo-coo-cool.

    The pressure inside the particles that make up every atom in the universe could be greater than the pressure inside the densest stars, according to a new measurement.

    Scientists at Jefferson Lab in Virginia calculated the pressure using the lab’s Continuous Electron Beam Accelerator Facility, or CEBAF, and some tricky mathematics. The measurement will mainly be useful for fundamentally understanding these particles’ nature. The calculation is pretty mind-boggling.

    “Neutron stars are some of the densest objects we know of in the universe,” Volker Burkert, Jefferson Lab Hall B leader, told Gizmodo. “It’s an order of magnitude bigger than that. It could be the record observation of a pressure on Earth.”

    The researchers calculated the pressure faced by the quarks that make up protons at 1035 pascals, equalling 1030 times the pressure at sea level, according to the paper published in Nature.

    ...


    So, what do you do with knowledge of the proton’s ridiculously high internal pressure? First, it’s interesting to know more about perhaps the most important particle to life, since without protons, there would be no atoms and no humans. And there’s still lots to know about protons: Just last week, another team at the Jefferson Lab measured a fundamental property of the proton, called its weak charge, for the first time.
    That seems like burying the lede, to me.

    This isn’t the first-ever measurement of the proton’s weak charge,
    Oh.

    since scientists working on Qweak performed a limited measurement back in 2013, Greg Smith from Jefferson Lab told Gizmodo. But that was essentially a preliminary run with 4 percent of the data. This new paper is the whole shebang.

    So, what use is the weak charge? It’s an important test of fundamental physics.

    The current state of particle physics is sort of like a partially explored cave with a shadowy regions. We think we understand the structure of the cave, but there could be entirely new chambers hiding in the shadows. After all, calculations suggest that the Standard Model of only describes 4 percent of all of the universe’s mass and energy, with mysterious dark matter and dark energy taking up the rest. That means the cave system could be far larger than physicists think. These experiments offer fundamental measurements to compare against theoretical predictions. If things are different, that could shine light on a new part of the cave.

    This new measurement was basically what predictions said it should be. “It is very consistent with the theory,” said Maxim Perelstein, a Cornell theoretical physicist who was not involved with the study. “The more measurements we have that are precise and agree, the better constraints we can put on theories extending the Standard Model.”

    It’s like you’re exploring the cave and you find a wall where you thought there might be a tunnel. For example, “for a very popular type of dark matter model, there is a ‘dark photon’ that can mediate the interaction between the dark matter and Standard Model particles,” Mu-Chun Chen, professor of physics and astronomy at the University of California, Irvine, told Gizmodo. “From Qweak, one can place a limit on the mass of the dark photon.”

    These results also offered the physicists another chance to measure the “weak mixing angle.” At high enough energies, the weak force and electromagnetism merge into a combined “electroweak” force. The weak mixing angle is an important number that relates these two forces once they separate, and Qweak offered some of the most precise measurements of this value yet.

    BZZZZT

    Something is wrong here. First, they obviously have the prefix wrong on Pascals. 1 atm ~= 101,000 Pa. Even assuming they got that wrong (they did), I thought 1,035 atm sounded absurdly low for record observation. Cripes, that's only about 15,000 psi. Child's play. That's routine.



    Edit: OHHHHHHH it was 10^35 Pa. ok, that might do it.

    Musk also announced on Thursday that the companys branded $500 not-a-flamethrower will start shipping to customers in just two weeks. Musk has faced a number of regulatory hurdles to get the product off the ground, which has led to a rather unusual delivery method.

    As somebody not all that enamored of the Beatles, I've always thought that song was quite good. 1. Story songs are the best songs. 2. Funny songs are great as long as they're funny (and it is). 3. For a band that spent the second half of their career deeply breathing in their own farts, it is pleasingly self-deprecating about the idiocy of their fans and their fame.

    I also like the song because Paul pushed it all the way and I hate Paul but I like the song for the same reasons he did, and I shake my head that the other 3 didn't get it. So this song reminds me that Paul was actually onto something, sometimes, when he wasn't staring at the mirror, which helps explain why John put up with him as long as he did.

    George and Ringo weren't all that excited about how long it took to record the song thanks to Paul insisting they get it exactly right. George would refer to it as one of Paul's, "fruity songs" although in the end I think he grew to like it. Ringo said it took, "fu***ng weeks to record" and didn't see the point in it.

    Lennon's distaste went deeper. It was recorded shortly after a car accident left him and Yoko quite injured and therefore he wasn't in the greatest of moods. Additionally John really hated that Paul often wrote from fantasy rather from a first person perspective - even if the made up evens he depicted were ultimately meant to convey his own feelings and experiences. John really felt all art should be personal and be drawn only from one's own experiences. To each their own.

    I'm not saying I agree with their criticisms but the reference to the song reminded me of the stories behind it.

    btw you're not really getting what the song was about. It was basically that, "s**t happens". As in things can be going along swimmingly and then, "bang, bang" something happens or comes along (a hammer) and ruins it all.

    But you have a stubborn and ill-informed narrative about the band and not sure I'll ever change that.

    LOL. Do tell me more about what I think.



    For the record my only "narrative" about the Beatles is that they're a band. They did a lot of really good stuff and a lot of really lazy stuff. Too many people identified with them too strongly for there to be a reasonable discussion of how good they are until those people are dead, and we still have about 20 years to go until that happens.

    Until then, they're Kanye. Love them or hate them; it's none of my affair.

    That's somewhat the narrative to which I refer as well as the previous post. You either enjoy their music or don't but this line of thinking kind of gets in the way of that.

    btw - they're not even my favorite band of all time so it's not a personal thing for me. To each their own and this isn't the best thread for the topic.

    Not a big Beatles guy either. But find it interesting you preferred the first half of the Beatles over the second. First half stuff seems too much from a different era. Second half was cosmic, but at least modern.

    Having said that, their best work by far was when they transitioned.
