Hi,

My name is Mark. I am a teacher of Mathematics and Physics and a recently retired Earth Scientist from the NASA - Goddard Space Flight Center. I have SB and PhD degrees in Mathematics from MIT and Cornell. I would like to share my knowledge and understanding of Mathematics, Physics, Earth Science, and Computers with the next generation of students and professionals. I have over 550 hours of tutoring experience in Mathematics, Statistics, Physics, Technical Writing, SATs/ACTs and related areas.

I am here to help you! I am here to help you master the powerful mathematical and scientific tools that will support your education and your career. I am here to present a broader, gentler picture of math and science and to demonstrate to you the enormous scope, power, and benefits of these subjects for almost any endeavor.

I am here to teach you to use your natural intuition and creativity to understand and solve problems in these subjects and in life in general. I am here to show you how to break problems down into small, manageable steps and to build up your self-confidence in applying the natural mathematical talent that you and everyone else is born with.

I have taught classes at Cornell University, the State University of New York, New York University, Columbia University, the University of Maryland, and at Marymount University in Arlington, Virginia.

Please let me know how I can help you.

Algebra 1

I have studied Algebra as an undergraduate at the Massachusetts Institute of Technology, and I have actively used it in my work at NASA in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Algebra 2

I have studied Algebra as an undergraduate at the Massachusetts Institute of Technology, and I have actively used it in my work at NASA in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Astronomy

I have studied Astronomy as an undergraduate at the Massachusetts Institute of Technology, and I am currently involved, through the American Geophysical Union, in a project to study the properties and characteristics of the Earth-like exoplanet, Gliese 581-d.

ASVAB

I am an experienced ASVAB tutor who has recently helped my student to successfully join the Navy by helping him to increase his ASVAB score from a 38th percentile ranking to a 52th percentile ranking.

Calculus

I have studied Calculus as an undergraduate at the Massachusetts Institute of Technology, and I have actively used it as a PhD student at Cornell University and in my work at NASA in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Differential Equations

I studied and taught Partial Differential Equations as part of my graduate work at Cornell University. My PhD thesis was on the derivation and solution of partial differential equations using the multi-scale methodology.

Discrete Math

I have studied several of the elements of Discrete Mathematics both as an undergraduate at MIT and as a PhD student at Cornell University, and I have actively used them in my work at the NASA/Goddard Space Flight Center in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System. I have taught Finite Math, a close cousin to Discrete Math, twice at the undergraduate level.

Ecology

I have vast experience at NASA in climate simulation modeling, climate variability studies, and climate change. I have also done development work at NASA in the global modeling of atmospheric pollution and chemistry.

Elementary Math

I have BS and PhD degrees in mathetmatics.

Elementary Science

I have over 30 years experience as a NASA scientist.

Finite Math

I have a taught an undergraduate course in Finite Mathematics at Marymount University in Arlington Virginia. I am already qualified in, and have over 20 hours of tutoring experience in the related and much more difficult discipline of Discrete Mathematics. I am also qualified and experienced in the tutoring and practice of the following component disciplines of Finite Mathematics--Algebra, Linear Algebra, Pre-Calculus, Probability, and Statistics.

Fortran

I have over fifty years of programming experience in Fortran, Fortran 77 and Fortran 90. I learned Fortran as an undergraduate at MIT, and have used it there, as a graduate student at Cornell University, and as a scientist and Senior Programer at MIT, at New York University, at the NASA/Goddard Institute for Space Studies, and at the NASA/Goddard Space Flight Center. I have over 20 hours experience in tutoring Computer Science students at the University of Maryland.

Geometry

I have actively used Geometry in my work at the NASA/Goddard Space Flight Center in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Linear Algebra

I have studied Linear Algebra as an undergraduate at the Massachusetts Institute of Technology, and I have actively used it in my work at NASA in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Logic

I have studied several aspects of logic both as an undergraduate at MIT and as a PhD student at Cornell University, and I have actively used them in my work at the NASA/Goddard Space Flight Center in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.

Music Theory

I have been a student of music theory and composition and have composed several shorter musical works.

Physical Science

I have more than 30 years experience at the NASA/Goddard Space Flight Center in studying and modeling the physics of the Earth's Atmosphere/Land/Ocean System.

Physics

I have more than 30 years experience at the NASA/Goddard Space Flight Center in studying and modeling the physics of the Earth's Atmosphere/Land/Ocean System.

Prealgebra

I taught Pre-Calculus, which included some Pre-Algebra, at the Undergraduate level at the State University of New York at Purchase.

Precalculus

I taught Pre-Calculus at the Undergraduate level at the State University of New York at Purchase.

Probability

I have studied probability as an undergraduate at the Massachusetts Institute of Technology and have applied and developed skewed and unskewed bi-Gaussian probability distributions at the NASA/Goddard Space Flight Center to describe the moist processes that occur in the turbulent atmospheric boundary layer.

Proofreading

I have been a peer reviewer for scientific journals, an editor for scientific and popular manuscripts published by my office at NASA and a freelance editor for scientific and technical publications.

SAT Math

I scored a 790 on my SAT Math test. I have received examination preparation training from Kaplan.

Statistics

I have a PhD in Applied Mathematics and have used statistics extensively in my research as an Earth Scientist at the NASA/Goddard Space Flight Center. I have computed and/or evaluated anomaly correlations to verify numerical weather predictions and to diagnose relationships between physical observations and possible causes. I have used statistical tools such as the Student test and Principal Components Analysis to better understand physical phenomena. I am also very experienced in applying statistical techniques and reasoning to simulate and understand atmospheric turbulence and dispersion.

I have also taught basic elements of statistics and probability within a college level course in Finite Mathematics.

Trigonometry

I have a BS and a PhD in Applied Mathematics from MIT and Cornell University. I have actively used Trigonometry in my work at the NASA/Goddard Space Flight Center in the mathematical modeling of the Earth's Land/Ocean/Atmosphere System.
