Macbook Air
January 15, 2008

Well, I’ve just seen a few pics of the newly announced Macbook Air, and I think it looks great (like almost every other Apple product out), however I’m a bit worried about one thing – the battery. It’s not user-replacable, like the  iPod, or iPhone, which means, if the battery dies out, you’re screwed. I know first hand how useful having a battery that youcan replace is. My brother’s Macbook’s battery discharged over time, so instead of sending it in and waiting for it to be fixed, he ordered a new battery and bam! back in business! I guess they could make a case that ‘due to the ultra-portable form factor, we had to have the battery encased in the laptop’, but I dunno…looks like a way to get more money in the long run, very much like what Sony did to it’s customers with the PS3 controller.

Although a lot of people may voice their dislike to Apple’s decision to have a battery in the Air that cannot be user-replaced, I’m sure it will still sell amazingly well, as it seems that people will buy anything as long as it has that little Apple logo on it.

BIO250 Lab 7
January 15, 2008

For Worksheet 7-1 remember:

EM gives great resolution, but often involves killing the cell, while LM has less detail, but allows you to study living cells in real time. 

Heres a link that will help for one of the questions in worksheet 7-2

I will post more tomorrow,

Update:

-Advantage to pelleting pure mitochondria would be that you can perform analysis on it without the interference caused by other organelles

-Appendix 1 contains a lot of info that is helpful for the pre-lab (7-1)

CHM247 Notes
January 10, 2008

From what I’ve been hearing, CHM247 this semester, is totally written based compared to last semester, and since I saved the files that they gave us last sem, sometime soon I will be posting up reaction flowcharts and possibly lecture notes.

 Cheers
