Weird stuff.

Actually, I believe you not only hear your heartbeat, but the blood flowing through your veins.

It was in response to the post above. Sorry.

Damn, really?

I thought they would surely have some sort of atmospheric pressure change due, in part, to simulating a vacuum-like environment. I obviously don't know, but that was an assumption I made.

Either way, that's cool stuff man.

Arteries. The pressure vessels transmit sound, your veins are merely conduits.

I really can't imagine what it would be like. I have hearing aids, and currently have about 78% hearing loss in both ears. Due to a youth of guns, mechanics, drums, and rock and roll. So sound and how it relates to the world around me has always been a little strange and intriguing to me. I can tell you that pressure has a lot to do with hearing. My hearing aids attest to that in pressurized environments. Whether a room is sealed, pressurized, etc. has a lot to do with how you hear. And there is a huge amount of what you hear that is processed by your brain without you knowing. You don't simply hear everything the same way. For instance, your brain has a way of muting your own screams and loud yells, so you don't hurt your own hearing. And in noisy conversation environments, your brain has a way of locking in to who you're communicating with and muffling background noise. Hearing aids completely fail to overcome those minor brain processes, which are blatantly obvious in some situations. I'm convinced that your brain shapes and adjusts what you hear much more than people realize, and plays a big role in how you perceive and navigate your environment.

According to the Drake equation of lurve, there should be 100 something women out there for me..

I call bullshit.

Are you using the right approach?

The Hubble pictures are awesome, absolutely awesome. They can be bought as posters, you'll have to search, I can't put the link on here.

The Deep Field from the Hubble are the best, IMO. All those little stars you see with your naked eye are actually galaxies, the Hubble Deep Field shows you that. Awesome.

This is something that I've always wondered about, due to the fact that we each interpret color on an individual basis. Your interpretation of red, could be another person's green....

Good stuff Fish. This is a quality post.

There is some pretty interesting stuff out there on colors.

[full on boring farmer mode]
I saw Kevin Price from KSU and his research on telematics. They took a camera and took the infrared filter off and tied it onto a model airplane with a GPS and coursed it's flight over fields. They then put some filters on it to show variations in biomass. They then used some software to link all the pictures together and offset perspective and end up with a mosaic of the field with a resolution down to 1 sq inch.

Anyway Price went through the infrared filters and how they work with different pictures. It's amazing what you can see when you filter out noise of different colors. They had a picture of a soybean in which half was healthy and half had some disease. They didn't look that bad to the naked eye, but when you look at it in infrared, it was drastic. The disease took out so much of the biomass it looked really bad.

I'll try to see if I can find the presentation, but it was fascinating to see what just changing the spectrum does.

I have ALWAYS wondered the color question as well. I thought it was just me, though. Rep.
