    I could be wrong but this article reads like AI. I don't understand why its getting upvotes.

    I don't think anyone specifically knows. If you ask the physics, they will point to changes (like pulse shape or component sizes) they made due to their increased understanding of …

    I mean NIF has spent a majority of its life (11 years) seeing yields below 200 kj. Only in 2021 did it jump above 1 mj and in 2022 above 3 mj. If your definition of breakthrough is…

    NIF's definition of Q was defined by the National Academy of Sciences and is analogous to the Q that MCF uses.

    The definition of Q that is being used was established by the National Academy of Sciences not NIF. NIF previously tied to use the hot spot energy instead of target energy in 2013,…

    No, this is ignition. However, the reason why this is a big deal is because it is scientific break-even. The first time they achieved ignition was in August of 2021. See paper belo…

    What is your point? That we should distrust everything in a scientific journal? You are shifting the goal post. First, you wanted a publication. Now, you say that would not be enou…

    If you were familiar with NIF, you would know that they absolutely will publish the details of the experiment just as they published the details of the experiment that achieved ign…

    The laser energy is converted to x-rays by the gold cylinder. But the cylinder only has a conversion ratio of 10~20 percent, so the amount of energy that gets deposited on the caps…

    It's amazing how people even in hacker news just say whatever they want with absolute certainty. This is ignition but ignition was achieved by their August 2021 shot. See this pape…

    That is only true to a certain point. Look up Paschen's law. After you go lower than a certain point, around 10 Torr cm depending on the gas, decreasing pressure increases the brea…

    Yea, the whole target bay is in vacuum which helps with the arcing.

    Sure we can wait, but there already has been publications about the August 2021 shot, in which they determined that the August 2021 met the ignition criteria. It's pretty clear tha…

    Many fusion new articles have this problem but i would argue that this time, how FT categorized this is appropriate. This is literally the first time the scientific break-even (not…

    Dylan was not insisting that every culture must be a mixture of foreign culture. He is just generalizing that multiple cultures is better than one. By the way, on aggregate, Americ…

    That's true. I guess if all the app developers pulled their apps out of the app store, the larger companies could just come in with their own version of all the apps.

    None those will ever happen unless developers/app companies for a union of some sort.

    If you knew you had a 60% chance of winning, wouldn't you want to bet a small amount to reduce variance? I guess on the down side that is A LOT of clicking. It is similar to how wh…

    Hi! Joining the party late, but why did you guys opt for the two propellers up/two propellers down design?
