  • Its part of iterative improvement. The resonance causes the beam to spread out, which both makes getting results harder and losing more particles in route. The resonance is caused by the magnets used being imperfect.

    The point of the article is they have created a model that predicts these resonances accurately. This will be of limited benefit to them, though it will help clean up some data. The big advantage for future constructions is by knowing how the field becomes imperfect, measures can be taken to correct for it. This will make future particle accelerators better. The same problem will occur in larger fusion reactors. By studying this now, they can be improved before they are even built.

    “In theory there is no difference between theory and practice. In practice there is a huge difference!”


  • That’s ok, not everyone gets that hit. A significant number of people (I want to say around 20%) don’t have the nerve connecting their pheromone receptors to their brain. It sounds like you are in that group.

    The bond will still form, it will just be later, and based on interactions, rather than hormonal. It’ll be worth it eventually. Just focus on being a good dad, even if it’s just by rote. It’ll come.


  • Believe it or not, that’s not an uncommon feeling. Evolutionary wise, there’s no particular reason for the dad to bond with the baby. It’s completely dependent on mum. What we get is often a spillover for the drive to get mum to bond.

    I was lucky and had that bond kick in quite quickly, but it’s ok if it doesn’t. Likely it will kick in around 6 months, as the baby becomes more “interesting”. Until then, be a good husband.

    It’s also worth noting that you are entering peak “emergency mode”. Right now the baby is completely dependent on you. It hasn’t settled down into a routine, and you are running low on sleep. They combine to utterly screw with your head.

    The mentality that got me through that zone was this: mum looks after the baby, I look after mum. I made sure she had regular meals. That she had time for a shower. That she could have a coherent night sleep.

    Something that might help is to sniff your baby’s head. Babies put off powerful pheromones, designed to reinforce the bonds. Unfortunately, not everyone has active pheromone receptors. If you do though, that smell is like crack cocaine.

    In short, you’re doing well. Baby is safe and cared for, and you’re doing your share of that work. Anything else is a bonus.






  • For those that struggle, the android app “alarm clock Xtreme” is excellent. You can set tasks you have to do before snoozing. Both maths questions and having to scan a barcode or tag are options.

    Combined with the “sonic bomb” alarm clock, it’s an extremely effective combination. (For both you and all your neighbours within a few 100m)

    Quantum mechanical particles are very different things to classical ones.

    A slightly better way of thinking about them is quantised fields. Particles and waves are simplifications of the underlying effect. There is no classical equivalent to work with to this, so we try and understand it as particle-wave duality etc.

    In this case, a carrier particle is a (quantised) disturbance in the underlying field. If it has enough energy, it manifests as a physical particle. The higgs boson is an example of this. Below the required energy, you get virtual particles. These “borrow” energy, and so can never be seen directly, only inferred.

    By example. Photons are the carrier particle of electromagnetism. Give the field energy and you get photons (light). Without that energy, the photons are virtual. Existing only between the 2 acting entities.

    Different fields have different carrier particles. The photon is quite simple. It’s effectiveness decays as 1/r^2 . The strong force carriers are more complex. They can emit more carrier particles, allowing the field to grow with distance rather than decay.

    To add more complexity. The various fields look to be aspects of the same field. At sufficient energies, they behave identically. We have figured out how to combine the electric, magnetic and weak fields. We have a handle on the strong field. The higgs field seems to also match into this. Gravity is a pain to study. We assume it should match in, but haven’t managed to work out how yet.

    As for why the underlying field exists and follows the rules it does? We have no clue right now. The ‘why’ tends to follow the ‘what’, and we have yet to get a good handle on the ‘what’.




  • As an Englishman, the IRA were fairly critical to the political results. They kept the UK government from running roughshod over the Irish political parties.

    The IRA proved they were willing to cross critical lines (bombs aimed at large scale civilian damage on English soil etc). They also demonstrated restraint. They often provided warnings ahead of time. They focused on disruption not casualties. The underlying threat was clear however. If you (UK government) escalate too far, it’s simple to switch from a bomb aimed at destroying a high street of shops, to one aimed at killing a high street of Christmas shoppers.

    The end result was that Irish politics stayed in the public eye, and the government took the safer path of negotiating in good faith. No-one was particularly happy with the results, but no-one was excessively unhappy with them either. Often the best you can hope for.

    In short, the credible threat is required to keep all parties honest. Most smart governments will see an escalating trail of protests as part of that. Unfortunately, the current US leadership doesn’t seem that smart.





  • Be careful with the taking average mindset. It’s a default human one, and it’s being abused. A lot of media outlets (particularly American right wing) are mouthpieces for the same few groups or people.

    Instead, try and look at their biases. Do they have a reason to mislead you. What akin do they have in a particular game. E.g. the BBC is still fairly unbiased on a lot of world news. They are far less unbiased on middle eastern politics now.

    It’s an annoyingly complex problem to solve, on the fly.

    Interestingly, English does have a “reference” accent. “Queens English”.

    Back in the days of the British empire, the aristocracy had a serious problem. When they traveled, the local population were difficult to understand, they all had accents. To solve this, the hired help were taught not just English but a clear “accentless” English. This meant the rich could go anywhere in the empire and not have to decode the local’s butchering of English.

    While it’s used a lot less now, it was only a few decades back that the BBC stopped requiring it for news broadcasts. It’s the “classic” British accent you see on TV shows.
