I put a light bulb inside a box and make it glow, is there a way to know where the light bulb is if the box is closed and not transparent
Sure. What are your thoughts?fredreload said:I put a light bulb inside a box and make it glow, is there a way to know where the light bulb is if the box is closed and not transparent
What is the context of the question? What are the constraints?fredreload said:We human have not advance far in science(I have no idea)
Yes, that would be one way. You need to take 3 x-rays to get the full (x,y,z) position.fredreload said:Some type of x ray vision? Some kind of imaging technique
Or 2, 2 dimensional x-ray pictures...berkeman said:You need to take 3 x-rays to get the full (x,y,z) position.
7. spinning the box to determine center of mass...anorlunda said:Changing the rules is the most fun part for the challenger.
jerromyjon said:12. sonar?
That would be adaptable I think... like how a bat could see it, perhaps.
I did at first and changed it... wasn't sure if it works through air...anorlunda said:call it ultrasound

...now I'm having fun wondering if bats can "see" through walls... too! I just googled it and found something about cellphone seeing through walls...anorlunda said:having fun finding all the loopholes in his problem statement.
...each of the fitted LEDs transmit a distinct location code
fredreload said:Well, how about a way to extract the light wave emitted by the light bulb? Is that possible
I suspect these questions are related to the questions that you've been asking about brain imaging in the biology form.fredreload said:Well, how about a way to extract the light wave emitted by the light bulb? Is that possible
rons99 said:By using thermal camera shoot the box surface from the top, front and right side could be known the light bulb position. Good luck.

Yes well, I've been thinking about ways to visualize the actual electrical synapses inside a person's head. Well, I got an idea of lighting up the sodium ion with wavelength 589nm, or the solar roof technique, but both requires looking inside the brain. I swear I saw my brain light up one night, I'm just not sure how people retrieve that signal(through the eyes?). We know MRI can retrieve radio signal because it passes through, but the resolution is low. So, I'd like some idea on how to visualize electrical synapsesYgggdrasil said:I suspect these questions are related to the questions that you've been asking about brain imaging in the biology form.
Anyway, if the bulb is incandescent, you could do thermal imaging (if the box is transparent to IR) to estimate the temperature of the filament inside the bulb. Since the light is produced by a well known physical mechanism, you could then model the spectrum of light output by the bulb based on measured parameters.
