    Speed of submerged submarine

    We've had a discussion on this before. I suspect this want true for traditional diesel Vs electric due to the maximum output for the two engine types.

    Quantum Superposition

    In entanglement (or superposition more generally) there is no information transfer. Causality is maintained. It's a pretty common misconception that there is information exchange, often due to sloppy pros in popsci articles.

    Science and Religion: A Math Theory Request

    As to the importance of mathematics in modern science. It's the language and the framework that the physical sciences are built. Repeatable predictions of physical measurements are fundemental to science, to do that accurately you need mathematics. "If I let go of this ball it will drop" is not as accurate as "if I let go of this ball, given the local gravity, air resistance and distance to the floor it will hit the ground in 7 seconds". You can then measure the 7 seconds and see if, given the relavent errors, the values are consistent with each other. As to the probability, even if it's very very very small, we should again refer to the great man (Douglas Adams),

    Dropping out of highschool

    Please don't take this as a negative on you. I want you to make the best (whichever that is) informed decision for you. None of your answer fills me with confidence. No, I didn't mean a software company. There's a distinct difference between someone who writes software and someone who is a software engineer (which would normally also include writing software). What you then go on to talk isn't quality assurance in the software engineering context. You wouldn't have scored highly. But that's ok at this stage, as long as you know that you're writing software rather than engineering then you can make an informed decision. Given your answer a follow up might be something along the lines of "what process did you go through to decide your database schema?"

    Dropping out of highschool

    I don't know much about the US system but the team I manage does include software engineers. You say you'd be working as one, do you really mean you'd be working as a software engineer or would you be doing programming for a company who don't really know what software engineering is? That could make a big difference to you when you come to get your next job. A pretty simple interview question for an entry level software engineer might be something like "what importance do you place on quality assurance and what tools and practices have you employed to demonstrate this in a particular project?" I'd suggest you need to think about this role, it's prospects both in the company and what you might want to do career wise next, after collage. You might also be interested to know that for university graduates we look at their a-levels as well (equivalent age to high school in the USA).

    Best lighting colors?

    Part of the reduction in brightness is due to how lumens are defined, humans are more sensitive to the bluer end of the spectrum and the scale is weighted. So the same energy coming out the front actually changes bassed on colour temperature of the light. There are other factors like the thickness and types of coatings used to on the LEDs to get a white spectrum out. They're getting better at that though (the Samsung options especially it seems). I carry an astrolux S1 with an xpl hi most days. The lower cri isn't a big problem for the most part. But it might be something worth thinking about in the context of the thread. Next time I have to think about kitchen lighting I'll take it into account. I find the led lights ive got at the moment not great for cooking meat.

    Best lighting colors?

    Warmer colour temperature (actually cooler in terms of the number, think below 5000 K) tend to give better colour rendition to the human eye. There is also some evidence that they are less straining on the eye. In the torch (flashlight).community cool white (above about 6000 K) are normally met with derision. 4000 K is pretty comme and gives a good mid-afternoon mid latitudes kind of light. If you're really interested in colour rendering you need to look at colour rendering index (CRI). It goes from 0 to 100 with 100 being close to sunlight colour rendering. Most decent LEDs will give you 70, it's not too hard to get up around 95. Nichia and Samsung make some good high cri LEDs. In my torches I can see a difference between 5000 K at 70 cri and at 95 cri.

    Mediocre in science

    In academia that's probably true. There just aren't the jobs or funding. In general it's not true though. I know people who work as scientists who were certainly not the top students. Some are better at the science than others. A science degree also gives you some great transferable skills. Many of my contemporaries are doing some interesting things which are often tangentially technical (e.g. finance director for the technical wing of a company, patent lawyer etc...)

  10. Just to add even more... If it's a pulse you can use time of arrival differences between multiple sites to do a triangulation. We really do need more information.

    Help with translation: professional exams

    No... not a single term. But there are professional bodies for which levels of membership may have certain criteria associated. For example I am a member of the institute of physics. To get the level of member I needed a supporter and to provide evidence of working at a given level as a professional phycisist for a given amount of time. Many of these bodies provide chartership as well as membership grades, e.g. chartered phycisist or chartered engineer.

    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.

    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).

    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.
