Happy Birthday Photographed People!

Fri, 18 Nov 2011 20:21:41 +0000

Today (November 18th) is the birthday of Louis Daguerre, a French chemist who invented the first type of photography that was fast enough to photograph people. The first photographs to be taken required hours to expose so they could really only photograph buildings. Even if there were people in the shot, unless they remained where they were for eight hours they didn't make enough of an impact on the film to show up. This means busy streets looked deserted on film, crowded building entries seemed empty, and even seated portraits were impractical. This all changed with Daguerreotype photography which could take an exposure as quickly as ten minutes. In 1838 (decades after people had been taking photographs) the first people showed up on film! For the first time in history, you could be shown on film exactly as you are instead of just how an artist saw you.

I saw a note about this somewhere and stopped to think about it a little. Today we have cell phones with cameras, digital cameras that can hold thousands of pictures, webcams, Google satellite images, Flickr accounts, and all sorts of wonderful photo options. With this wealth of photos, though, do images seem cheaper? If you can't remember the first time you saw a picture of a person, it becomes more like grass: you know it's there and you like it but you rarely think about that.

Chemistry Again.

Today we read an article about St Louis and how we use to have a town call wellston springs and how the town is now a park... It was very interesting because i never thought that saint louis could have really bad floods. It shocked me to know that 18,000 people went homeless. It was really a tragic. Today we also did some activies about colors and candles. That also was fun.

well this week has been cool went and tought some peers and played bball at lunch we did the floating bubbles experiment and it was cool never seen bubbles float in mid air it was crazy but that's pretty much it...

This week in mystery o matter

Thu, 30 Jun 2011 18:11:23 +0000

Dear Blog, This week in mystery of matter we have been working with a new experiment which involves floating bubbles. After last weeks sucessful flash mob we have another one for next week in the works. This yime around the mob includes edible slime, thats right slime that you can eat. We made 2 different flavor slimes (orange and Chocolate). Personally I think the chocolate flavor tastes better. We shot a promotional video for chemisty week/mystery of matter last week. The video is a Qvc sketch show advestising liquid nitrogen. We had a couple of mishaps and mistakes but over all it was fun to make. Colin has produced a rough eidt of the footage but it will be reedited to get rid of mistakes. The video will be posted on the yes site after its completion. Well that pretty much wraps up this week in mystery of matter. Sincerly, Alan P.S your in for a good show

Well This pass few weeks we have been doing flash mobs and they have been going great. We did one with lycopodeun, and i had to pop out of behind the desk and say thanks for watching and what kind of experiment was it.. That was pretty fun.This week we saw the body worlds exibit and that was so fun and interesting. To lesarn about all the body parts and our insides. That was awesome.... This week was okay.

This week was okay. We did some chemistry experiments , which were very fun. I cant wait to learn more experiments next week. i Want to explode stuff. use more chemicals... I Just hope next week will be be even greater.

New chem lab curriculum for this semester

Wed, 24 Jan 2007 17:07:06 +0000

I made a new curriculum around solvent chemistry. I used a lot of info and background from Becker Demos.
