About Leonard

I have always enjoyed teaching and helping others to learn. My formal education includes a BS in Physics, a Masters in Photonics/Optoelectronics, and additional coursework in optics. I also have extensive programming experience. As a tutor, I am patient and I work to make the material interesting.

About me: I spent 10 years working for the Caltech/NASA Jet Propulsion Lab on advanced optical systems. This work included camera alignment for the Mars rovers Spirit and Opportunity. For the last 6 years I have worked independently and started three technology companies. I live in Washington, DC with my girlfriend. In my spare time I enjoy playing go.

Physics:

My first technical job involved calibration of an X-ray astronomy satellite. Since then I have worked on instrumentation and analysis for a number of astronomical and earth-observing science systems. There is a lot of applied physics in this work. I think I have a talent for visualizing physical concepts, and I incorporate this into my tutoring. Visualizations help with understanding and development.

Math:

Math has always been a strong point. I enjoy the abstractions inherent in math at all levels.

Programming:

I know approximately 10 languages. I emphasize Matlab in my profile since I use it almost daily for analysis and graphing. I have used Matlab extensively since 2000.

I look forward to hearing from you and helping you achieve success in your studies.

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

ACT Math

I did very well on the math SAT and (in college) the math GRE. The math ACT is a very similar test. There are a lot of tricks and short cuts. Many of the problems on the ACT are the same as from previous years, just tweaked a little. Working through old tests and looking for these patterns is a great way to prepare.

Algebra 1

Algebra 1 covers a lot of topics, such as equations, inequalities, functions, graphing, polynomials, factoring, and rational expressions. Many of these are interconnected with each other. There are a huge number of practical applications, and learning about them can help make the material fun. Let's work together to empower you in this class!!

Algebra 2

I enjoy tutoring Algebra 2 (aka precalculus, but minus trig in some curricula) because the subject is so empowering. Algebra 2 completes the formal study of the elementary functions - polynomial, exponential, logarithmic, rational, radical, piece-wise, and trigonometric. Parametric equations, vectors, and infinite sequences and series are also studied. Working together we can help you attain the confidence you need to succeed!!

Calculus

Calculus includes the formal study of limits, derivatives, and integrals (and series in the case of AP Calculus BC). With my background in physics I especially enjoy the study of calculus because of the deep connection between the two. And of course there are many practical, real-world applications. Calculus is challenging, for sure. But whether you are studying for AP Calculus AB or BC, or another version of the course, let's work together to help you conquer the subject and (hopefully) have fun at the same time!!

Linear Algebra

I received an "A" in honors Linear Algebra in college. The subject comes naturally to me. I have used linear algebra extensively since then in my work in physics. Two linear algebra resources I recommend that are both free are (1) Gilbert Strang's online course through MIT OpenCourseWare, and (2) the online Khan Academy. Strang's textbook, "Linear Algebra and Its Application," is one of the best textbooks I have had in any subject, but there are other good linear algebra textbooks also.

MATLAB

Matlab is widely used in academic research, engineering, and elsewhere. I love the language because it is so carefully designed, written and documented, so effective for high level scripting, and so adept at generating attractive figures. I have been using Matlab extensively since 2000, and currently I use it almost daily. I recently started two companies to license Matlab software I have written. I have taken classes in a number of programming languages, but Matlab is my favorite.

Physics

Physics can be overwhelming, but I am here to help. A course such as AP Physics 1, 2, or C is a big step into a new way of thinking. Doing lots of homework problems is very important. I also try to show the big picture of how the concepts fit together and explain context. Physics is the most basic of all the sciences. Chemistry, biology, astronomy, etc. all have physics at their core. Kinematics, energy, momentum, rotation, waves, and electromagnetism are examples of key concepts. I try to make them interesting and fun!

Precalculus

I enjoy tutoring precalculus because the subject is so empowering. Precalculus completes the formal study of the elementary functions - polynomial, exponential, logarithmic, rational, radical, piece-wise, and trigonometric. Parametric equations, vectors, and infinite sequences and series are also studied. Working together we can help you attain the confidence you need to succeed!!

Probability

Probability and statistics are strong points. I can help with AP Statistics, which covers patterns and departures from patterns, sampling and experimentation, exploration of random phenomena using probability and simulation, and statistical inference. My first job after college included development from scratch of software for non-linear parameter estimation from statistically noisy data. Careful consideration of subtle statistical effects was very important. Since that job I have continued to use statistics for a number of projects and tasks. Let's work together to help you with this exciting subject!

Trigonometry

Trigonometry involves trigonometric functions and graphs, inverse trigonometric functions, trigonometric identities, and angle formulas. The subject has millions of real life applications in lots of different fields including physics, engineering, geography, business, and more. Trig questions appear frequently on standardized tests such as the SAT and ACT. The subject can be difficult, and includes lots of functions with obscure sounding names. By the end you will understand what is so funny about the Onion headline "Nation’s Math Teachers Introduce 27 New Trig Functions." But working together hopefully we can make the subject tractable, fun, and empowering.

Very knowledgeable

Leonard was very helpful and knew how to do all the problems we went over. We went over the review packet for the final. He was patient and allowed me to figure out how to answer the problem.
