My Courses

2017 Fall – MAT 2071 Proofs and Logic – Reitz

2017 Fall – MAT 2071 Proofs and Logic – Reitz

This course is designed to prepare students for an advanced mathematics curriculum by providing a transition from Calculus to abstract mathematics. The course focuses on the processes of mathematical reasoning, argument, and discovery. Topics include propositional and first order logic, learning proofs through puzzles and games, axiomatic approach to group theory, number theory, and set theory, abstract properties of relations and functions, elementary graph theory, sets of different cardinalities, and the construction and properties of real numbers.

Urban Tourism

Urban Tourism

This course will examine urban tourism as a vehicle of urban renewal and economic regeneration. The roles of government, business, and the community will be explored as well as issues of development, management, the environment and social equity. New York City and Brooklyn will be evaluated as models for the development, challenges and opportunities of urban tourism.

2017 Spring – MAT 2680 Differential Equations – Reitz

2017 Spring – MAT 2680 Differential Equations – Reitz

A differential equation is an equation that relates a function to one or more of its derivatives. – The above rather boring description does little to convey just how fundamental, widespread, and amazingly effective differential equations are in describing the world around us. – Examples: Anything in motion. Also, many things that are not in motion. Also, many additional things to which the word “motion” does not really apply. – Further examples: spaceships in orbit, populations growing and shrinking, a cup of coffee slowly cooling, springs bouncing, financial markets rising and falling, electrical current flowing through a circuit, ocean waves, sound waves, light waves, vibrations in musical instruments and airplane wings and suspension bridges, – More examples: Pretty much everything. Topics include methods of solving ordinary differential equations and applications to various problems.

My Projects

The Buzz

The Buzz

Welcome to The Buzz, a project by your student community team. The Buzz is a student blogging site dedicated to all things CityTech–from how to handle the pressures of school, to what movies to see. At least one of our student writers will post something every weekday, so check back often to join the discussion! And be sure to join the project to get regular updates!

2017-2018 Opening Gateways Faculty Seminar

2017-2018 Opening Gateways Faculty Seminar

“Opening Gateways to Completion: Open Digital Pedagogies for Student Success in STEM” is a 5-year, $3.2 million grant funded by the U.S. Department of Education’s Supporting Hispanic-Serving Institutions program (Title V). The goal is to support student success in mathematics courses that serve as gateways to STEM disciplines, courses that often act as barriers to progress and completion in these disciplines. The project, awarded jointly to the New York City College of Technology (lead) and the Borough of Manhattan Community College (partner) in 2015, brings the two institutions together in a cross-campus collaboration that will introduce open-source digital technologies, open educational resources, and active learning pedagogies into the sequence of high-enrollment mathematics courses required for STEM disciplines at each college.

Opening Gateways Project Management

Opening Gateways Project Management

This is a private group for members of the management team of “Opening Gateways to Completion: Open Digital Pedagogies for Student Success in STEM,” a Title V Cooperative Arrangement grant funded through U.S. Department of Education’s Supporting Hispanic-Serving Institutions program. The project, a collaboration between City Tech and the Borough of Manhattan Community College, is focussed on using Open Digital Pedagogies to increase student success in gateway mathematics courses for STEM disciplines.

My Clubs

Math Club

Math Club

What do mathematicians do? Can mathematics be fun and interesting? Do you like free pizza? The Math Club is open to everyone with an interest in logic puzzles, games of chance or strategy, and mathematics in general. We host a variety of math related events, math talks, math games, math puzzles, field trips, math competitions, and more. Feel free to stop by on Thursdays in Namm N719, from 1-2pm.

Student Government Association

Student Government Association

The Student Government Association is the representative body for students. We are responsible for recommending student activity fee allocations, shaping policies affecting student life, coordinating extracurricular events and chartering new organizations. Feel free to contact SGA President, Lucas Almonte, with any questions, suggestions or concerns. He can be reached at SGAPresident@CityTech.Cuny.Edu If you wish to start a club on campus contact SGA Vice President, Sylwester Dombroski, at SGAVP@CityTech.Cuny.Edu
