This course provides an introduction to the physics and chemistry of the atmosphere, including experience with computer codes. It is intended for undergraduates and first year graduate students.

This subject deals primarily with the basic principles to understand the structure and reactivity of organic molecules. Emphasis is on substitution and elimination reactions and chemistry of the carbonyl group. The course also provides an introduction to the chemistry of aromatic compounds.

This course studies what is language and what does knowledge of a language consist of. It asks how do children learn languages and is language unique to humans; why are there many languages; how do languages change; is any language or dialect superior to another; and how are speech and writing related. Context for these and similar questions is provided by basic examination of internal organization of sentences, words, and sound systems. No prior training in linguistics is assumed.

24.901 is designed to give you a preliminary understanding of how the sound systems of different languages are structured, how and why they may differ from each other. The course also aims to provide you with analytical tools in phonology, enough to allow you to sketch the analysis of an entire phonological system by the end of the term. On a non-linguistic level, the course aims to teach you by example the virtues of formulating precise and explicit descriptive statements; and to develop your skills in making and evaluating arguments.

This course explores topics related to the representation and expression of propositional attitudes (e.g. belief, knowledge, and desires) and speech acts (e.g. saying and asking) in natural language. The main focus will be on semantics of predicates such as believe, know, want, say, ask, etc. Other topics will include the syntax of main and embedded clauses and formal representation of the pragmatics of conversation. The course provides practice in written and oral communication.

This course will investigate the semantics of generic sentences, i.e., sentences that are used to talk about habits, tendencies, dispositions, or kinds. For instance:

1. Dogs are good pets.
2. The giant panda is an endangered species.
3. A soccer player makes lots of money.
4. Mary smokes after dinner.
5. This machine crushes oranges.

This is a half-semester course.

This course is designed to allow participants to engage in the exploration of the grammatical structure of a language that is unknown to them (and typically to the instructors as well). In some ways it simulates traditional field methods research. In terms of format, we work in both group and individual meetings with the consultant. Each student identifies some grammatical construction (e.g. wh questions, agreement, palatalization, interrogative intonation) to focus their research: they elicit and share data and write a report on the material gathered that is to be turned in at the end of the term. Ideally, we can put together a volume of grammatical sketches.

The first three to four weeks of the term, our group meetings will explore the basic phonology, morphology and surface syntax for a first pass overview of the language, looking for interesting areas to be explored in more detail later. During this period individual sessions can review material from the general session as well as explore new areas. At roughly the fifth meeting, individual students (typically two to three per session) guide the group elicitations to explore their research topic.

This course deals with the application of structure and theory to the study of organic reaction mechanisms: Stereochemical features including conformation and stereoelectronic effects; reaction dynamics, isotope effects and molecular orbital theory applied to pericyclic and photochemical reactions; and special reactive intermediates including carbenes, carbanions, and free radicals.

This seminar is designed to be an experimental and hands-on approach to applied chemistry (as seen in cooking). Cooking may be the oldest and most widespread application of chemistry and recipes may be the oldest practical result of chemical research. We shall do some cooking experiments to illustrate some chemical principles, including extraction, denaturation, and phase changes.

This course covers the principles of main group (s and p block) element chemistry with an emphasis on synthesis, structure, bonding, and reaction mechanisms.

This course is concerned with the concepts and principles which have been of central significance in the recent development of syntactic theory, with special focus on the "Government and Binding" (GB) / "Principles and Parameters" (P&P) / "Minimalist Program" (MP) approach.

It is the first of a series of two courses (24.951 is taught during the Fall and 24.952 is taught in the Spring). This course deals mostly with phrase structure, argument structure and its syntactic expression, including "A-movement". Though other issues (e.g. wh-movement, antecedent-contained deletion, extraposition) may be mentioned during the semester, the course will not systematically investigate these topics in class until 24.952.

The goal of the course is to understand why certain problems have been treated in certain ways. Thus, on many occasions a variety of approaches will be discussed, and the (recent) historical development of these approaches are emphasized.

This course is the third and final part of our graduate introduction to semantics. The other two classes are 24.970 Introduction to Semantics and 24.973 Advanced Semantics. The semester will be divided into somewhat independent units. One unit will be devoted to conversational implicatures (mainly scalar implicatures) and another to presupposition. In each unit, we will discuss basic concepts and technical tools and then devote some time to recent work which illustrates their application.

Many details of phonetic realization cannot be predicted from standard phonological representations on a language-independent basis, so phonetic realization must be specified in grammar. In this seminar we will investigate phonetic realization as a component of grammar.

The basic questions that we will address are:

• What is the form of the phonetic realization component?
• What is its relationship to phonology?
