Calling that transparent aluminium is a bit like calling (quartz) glass "transparent silicon" or lead glass "transparent lead".

Glass IS transparent silicon dioxide. What is wrong with saying that?

Silicon != Silicon Dioxide

Silicon != Silicon Dioxide

Okay, transparent silicon.

It is transparent silicon dioxide, but it is not transparent silicon, because it's not silicon.

If you ask for an oxygen bottle and get a bottle of water, ...

Is there silicon in glass. Can you see through it. Or are you saying a silicon atom is no longer a silicon atom if it's bound to another atom?

We normally distinguish between wood, coal, diamond, water, oxygen and carbon-dioxide. We do not normally fill a CO2 fire extinguisher with "transparent carbon".

Here's a spoiler regarding the recent posts. The movie also involves whales, not shown in this video.

All right, fine. Here's a whale or two for good measure.

..., unless we're smuggling diamonds. (Presidio, great movie.)

CO2 is transparent, right?

I can play nitpicking games all day too. :)

 

[mfb]

CO2 is transparent, right?

Yes, but it's not carbon. See above. It contains carbon.

So you can see through the oxygen but not the carbon. So you see little black dots?

I am pointing out the fallacy in his logic.

 

[ergospherical]

I am pointing out the fallacy in his logic.

what fallacy? the optical properties of compounds like carbon dioxide are determined by the vibrational modes of the molecule (e.g. CO₂ has a symmetric stretch, an antisymmetric stretch and a bending mode), and these have frequencies in the infrared (not visible) region so it is transparent. [Although, the symmetric stretch doesn’t change the dipole moment, so actually isn’t even IR active]

It’s not like some types of individual atoms are opaque and others are transparent…

It is easily possible to explain dark matter and dark energy. I have discovered a truly marvelous theory of this, which this room is too dark to write down.

Is this your last theorem, Mr. Freshmat?

the Schrödinger equation did me bad! I went into it thinking its probably beautiful and elegant as it describes the fundamental nature of reality. I couldn't have been more wrong! solving the eqn for a measly H-atom makes me cri

Simple!

Where
E = dark energy
m = mass of dark matter

Wouldn't you have to replace that with the speed of dark?

 

[Ivan Seeking]

Wouldn't you have to replace that with the speed of dark?

That's just - C. The squared value is still a positive.

Easy Peasy

I don't know what all the fuss has been.

My psychic prediction: Everyone who reads my post will secretly run a few calculations just to be sure what I said doesn't makes sense.

Done.

Today I was walking through a doorway so slowly that I started to diffract. Scared the heck out of me!

And the room you were walking into had two tall, narrow windows?
