  1. Align atoms by vacuum

    Arduino does make home labs much more accessible. You need to find some way to rule out the vacuum pump and associated electrics from being the cause of the magnetic fields. Which is far far more likely than what you're proposing. But I have to commend you for actually doing an experiment and improving it based on feedback. Experimental physics isn't easy, I would anticipate a fair few iterations of the experiment before you've rulled out most of the obvious interferers.
  2. How does a battery powered infrared transmitter work?

    That's pretty much exactly what I was thinking. Arduino is great for things like this. With esp8266 and ittt you can make an Alexa controlled remote (other home automation services exist).
  3. How does a battery powered infrared transmitter work?

    Ah yeah. I expect you're right. You can even get (or at least build) ones that you point other remote controls at and can remember what they receive.
  4. How does a battery powered infrared transmitter work?

    I don't know, remote controls were around before the advent of small cheap microprocessors. If the non microprocrssor solution works, is reliable and cheap I suspect it's still quite common. Probably something clever with cheap timing chips. I'm not sure if the question was about the modulation of the actual photon generation?
  5. Help with college pursuits

    Maths, all the maths at highschool level. Photonics rather than particle physics but of my contemporary PhD students I would suggest that 1 in 5 is probably a fair value for the number of people who stay in academia. I don't work in l anything close to my PhD subject but I do collaborate with some particle phycisists. I wouldn't get too caught up in the difference between a theoretical phycisists and an experimentalist. It's rare that the line is very strong in my experience. Although I almost always refer to myself as an experimental phycisist, at least two of my papers are pretty much theoretical model development with some experiments to test it.
  6. Engineering Degree Questions

    It'd be helpful to know where you want to study (country) and your end goal
  7. Salvation from Evil

    Modern changes to the story. He was really happy for the chance.
  8. Salvation from Evil

    That reads like wishful thinking and is subjective. Child sacrifice happened almost universally for probably thousands of years. There's even some who argue that Abraham not sacrificing his son but using an animal instead is a more modern change from him actually sacrificing his child. God? That's not evidence, just more subjective wishful thinking.
  9. Salvation from Evil

    I don't think they do. Humans have conducted child sacrifice in the past. They didn't think it evil.
  10. Christ is divine!

    If it was a falcon and not a hawk then it's a different type of bird. Maybe he was trying to give you a positive negative answer. Or... It it's just a combination of a very very big sample size and confirmation bias.
  11. Salvation from Evil

    Can you start by carefully and unambiguously defining what you mean by "real" and "evil"?
  12. Which Computer are used in Banking

    RTYBRBTYBRT, what's the point you're trying to get at here? That's not an either or question. Both can be true.
  13. Finding a researcher's bibliography

    That will always be the case. You will not catch fish outside of where you cast your net. You could try searching all of the larger databases, Google scholar, web of science, Google books etc... But there is still the chance of missing things. The easiest way is probably by asking the researcher. Although I've been known to forget my own publications. Especially the less formal ones (e.g. conference proceedings).
  14. What happened to the riverwall?

    Where in Somerset is this? (I didn't realise you were that close) I'm wondering if the vertical velocity from the Weir might have caused a very gradual undercut. Which possibly together with the recent very dry warm spell causing some movement above the low water line has caused the drop. The fault in the wall following some weak point, possibly a repair or showing how it was built in sections?
