Indivisible pebble, eh? =P Well, the quantisation of energy for electrons certainly amazed people. I am still in college, and working towards the day I can tell to a youngie that I study the complicated working details of things all the time too. But the working of algebra in a physics...

Yes. Physical quantities do take real values, but we can only measure them to a specific degree of precision. Got no tools or instruments for that. =P No division on an instrument could be the smallest, you could go on making the smallest divisions smaller and smaller, and increasing it's...

I am not exactly sure, but when you blow air into an organ pipe, the stream of air splits into two. One going through the pipe, the other going around the outside of the pipe. A wavering sort of vibration is set up. And when the frequencies of the vibrations are right, stationary waves are...

So, it is white light then. That solves it. Thank you. The spectrum does not have common frequency but common speed. My bad. Sorry. =D So that's why we get a complete spectrum. But then, what source of white light do they use in double slit diffraction experiments in a closed room? It...

But then if the blue light is scattered, then how do we still see the blue end of the spectrum when we disperse light close to the surface of the Earth? Also, if it's more intense in the yellow spectrum, then isn't it equally intense in the blues and reds spectrum by the look of dispersion of...

I am guessing this is due to diffraction due to the small size of the molecules of air. But then, we never see diffraction effects (interference) for any arrangement or configuration of molecules in space?

Light from the sun can be dispersed into its spectrum of colours. But when we look around us, and at the sun, it appears yellow. Then shouldn't it only be emitting the yellow part of the spectrum? We also use 'white light' sources when diffracting light through double slits, but then I couldn't...

It was a bit of both, but I actually wanted to know with relation to physical quantities. But this is good insight about continuous numbers. So then, real, continuous numbers are multiplied that way, and it doesn't really mean what multiplication means generally. And I think physical quantities...

Thank you, I think this is what I was looking for. So, it's just Mathematics can describe relationships between physical quantities too, without it necessarily being a 'multiplication' of some sort.

I surely will give it a read! =D

Hmm. I think I see it. This is how it works then. Thank you. =)

Oh. I didn't know it worked like that. Sorry. I'll take care now.

Thank you for the reference of the book. I'll try to get my hands on it as soon as possible. But then, in this case, wouldn't it be a somewhat 'rate' multiplication. Like, I am covering 2 metres per second, so how many metres I cover in 10 seconds would be a sort of 'rate' multiplication. Not of...

Fire Hmm. Thank you all. I think I get it. And yes, I should've Wikipediad it first. =D But it was also the behaviour of flames in which I was interested, and I think I get it now.

So like in a bunsen flame, while we are burning barium, it uses the heat energy of the bunsen flame and reacts with oxygen, producing a flame of its own, coloured green? I guess that is the colour. So what is in that green flame? Barium oxide?
