6.3 Valence-shell electron-pair repulsion theory

The theory of molecular shape that we have been working towards is called valence-shell electron-pair repulsion theory (VSEPR theory). When applied to molecules and ions of the typical elements, its success rate is high. Here is a stepwise procedure that you can follow when applying this theory. It is illustrated with the molecule XeF4 and the ion C1O3. Xenon tetrafluoride is one of the select band of noble gas compounds that were unknown before 1962

Computadoras y Arquitectura en la Era Digital (Computers and Architecture in the Digital Era)
It seems that when architects think, and talk about computers, they only reflect on very narrow images of the phenomenon. Architects think that the impact of computers in their profession is only related to how PCs, CAD/CAM, networks, software, peripherals, can improve the way they work today. Architects, by enlarge, are unable to reflect beyond the screen of their computers and the wall of their offices when it comes to recognize the real consequences resulting from the new technological advanc

Lecture: Reasoning from Race, with Serena Mayeri
Serena Mayeri, Professor of Law and History at the University of Pennsylvania Law School, discusses the intersection of feminism, law, and the civil rights revolution. The talk considers the case of African American activist Pauli Murray, who confronted the injustice she called "Jane Crow" when she was informed in 1944 that she was "not of the sex" entitled to attend Harvard Law School. In the 1960s and 1970s, the analogies between sex and race discrimination pioneered by Murray became potent we

The Pit and the Pendulum - Rap Song
A fun rap about Edgar Allen Poe's short story "The Pit and the Pendulum."  You can read the original text by Poe or watch/read this remix of the classic poem.  "The Pit and the Pendulum" is one of Poe's most famous works: a story full of suspense but not of plot. In fact we know very little about the characters in the story. The story has a claustrophobic feel to it that matches the main character's own predicament as he tries to survive the tortures of the pit and the pendulum.
