The first scanning electron microscope (SEM) was invented by Manfred von Ardenne in 1937 (McMullan). However, further development of the SEM was accomplished by Charles Oatley and his colleagues at Cambridge University (McMullan; Egerton 17). He and his colleagues acquired their first images from the SEM in 1951 (Egerton 17). The SEM was developed because if a TEM is utilized, a specimen must be made extremely thin to prevent the electrons from dispersing inside the specimen and so the electrons…

continued shad population will be too significant by blocking fish passage. This is similar to a case between the Tennessee Valley Association v. Hiram Hill, where a dam was being built on the Tennessee River, and a small endangered fish called the snail darter was going to die off if the dam was built.TVA argued that they had already put a lot of money into the dam, it was already close to completion, and the ESA was passed after the dam was built. They also argued that killing this fish would…

Nitro-junkie & Badmotorjam I have a natural appreciation for muscle cars, classic automobiles, motorcycles et al. I also love movies, and my penchant for these appreciations means life stories are analogous to all things with engines and celluloid. What’s even better is there is never a shortage of stories to tell. Last week’s adventure at the pump was eye opening for me anyway. Yet, I have noticed that whenever someone sticks their neck out to write about the topic of masculinity, some people…

Zukin proposes that the Internet has three paradoxes. The first is that the Internet grants us the privilege to shop anytime and anywhere, which makes online shoppers shop more.

And the third is that the Internet makes every buyer into a seller thanks to auction sites like eBay and Amazon. (Zukin, 2004) These are all…
