Book review of The Language Instinct by Steven Pinker

I have always been interested in language. When I was small, I discovered my love of etymology through vocabulary tests. I realized that I remembered words much more easily if I knew how these words were “built”, so to speak. For instance, the word “decimate” was much easier to memorize when I knew that it basically meant “to kill one in ten” in Latin. Eventually, my love for language grew; so much, that I am probably going to major in one, if not two foreign languages here at Bryn Mawr. So it was very fortunate for me when Professor Grobstein recommended that I

Man vs. Machine


In Kurt Vonnegut’s Galápagos, Vonnegut acts as a first-person narrator who tells a story

of the evolution of people from the 20th to the 21st century. Vonnegut’s evolutionary story

mocks the human race, and more specifically the human brain and its intellectual in creating

technological machinery that is almost as useless as the brain.

Who's to decide which side?

	In the neural system, each hemisphere of the brain corresponds to the
opposite side of the body with one side being dominate. This inborn
characteristic of the humans’ renders us lateralized because, for
example, the dominance of the right cerebral is responsible for left-
handedness and vice-versa. (1) A great majority of humans are
right-handed, 85-90% while the remaining percentage is left-handed. (5)
But why is there such an unequal distribution? This can be due in part by
both social and consumer influences because they help finalize the
handedness of a person. For the right-handed culture we live in has lead
to many more individuals converting from left-handedness to
right-handedness than to right-handedness to left. (16)

The Importance of Melanin

      Skin is the body’s largest organ and is very essential for our survival; it is what protects all our other organs from antigens that are detrimental to our health. The book Skin: A Natural History by Dr. Nina Jablonski is a very informative chronicle on how our skin protects us and at the same time allows the world to see one’s state of health, identity, and uniqueness.

Coincidence in Evolution in "Chance and Necessity"

I think the element of Biology 103 that I enjoyed most was its ability to answer all my ‘big questions.’ Before the course, I did not understand molecular evolution, the purpose of the scientific method, or how chemistry was connected to biology, and I left feeling pretty confident in my comprehension of these things. Because science is a loopy storytelling process, though, I was continually reassessing my ideas of what these processes meant, in particular, evolution. While our society’s great debate on evolution often hinges on the idea that evolution denies the ‘miraculous’ associated with a divine being (like that of creationism or intelligent design), the play between genes and environment and particularly  improbable assembly certainly seemed miraculous to me.
