Courses offered

  • Introduction to calculus

    • Duration: 1 Month
    • Delivery mode: Online
    • Group size: Individual
    • Instruction language: English
    • Certificate provided: Yes
    This course introduces the fundamental concepts of differential and integral calculus. Unlike previous math courses that focus on static values, Calculus examines the mathematics of motion and change. We begin by exploring the concept of a limit, which allows us to bridge the gap between discrete points and continuous functions.

    Students will learn to calculate derivatives to find the rate of change at a specific moment and integrals to calculate the accumulation of quantities over time or space. The course concludes with the Fundamental Theorem of Calculus, which reveals the elegant relationship between these two seemingly opposite operations.

  • Introduction to chemistry

    • Certificate provided: Yes
    This course provides a comprehensive introduction to the fundamental principles of chemistry. We begin at the subatomic level, exploring the structure of the atom and the arrangement of the Periodic Table. Students will investigate how elements bond to form compounds and how these substances interact during chemical reactions.

    The course emphasizes both theoretical understanding and quantitative problem-solving. You will master stoichiometry (the "math" of chemistry), explore the behavior of gases, and dive into the world of thermodynamics to understand why some reactions happen spontaneously while others require a push.

  • Integral Calculus

    • US$100
    • Duration: 1 Month

    This course explores the theory and applications of integration, the inverse operation of differentiation. We begin by solving the "Area Problem"—finding the exact area under a curve where standard geometry fails. Students will transition from Riemann Sums (approximating area with rectangles) to the Definite Integral.

    A major focus of the course is mastering various techniques of integration, such as Substitution, Integration by Parts, and Partial Fractions. These tools allow us to solve complex problems in physics and engineering, such as calculating work, fluid pressure, and the volume of irregular 3D objects.

  • Fluid Mechanic

    • US$150

    This course examines the physical behavior of fluids—both liquids and gases—at rest and in motion. We begin with Fluid Statics, calculating the forces exerted by fluids on submerged surfaces, such as dams or tank walls.

    The core of the course transitions into Fluid Dynamics, where we apply the laws of conservation (mass, momentum, and energy) to flowing systems. You will learn to use the Bernoulli Equation and the Navier-Stokes Equations to predict pressure drops, flow rates, and the impact of viscosity. The course also introduces the "magic" of Dimensional Analysis, allowing you to predict how a full-scale airplane will behave based on a small model in a wind tunnel.

  • Introduction to physics

    This course introduces the fundamental principles of Classical Mechanics. We begin by exploring Kinematics—the study of motion without regard to its cause—before diving into Dynamics, where we use Newton’s Laws of Motion to understand how forces like gravity, friction, and tension change that motion.

    Students will move beyond simple motion to study the "big three" conservation laws: Energy, Momentum, and Angular Momentum. The course concludes with an introduction to Oscillations and Gravitation, providing the tools to calculate everything from the period of a pendulum to the escape velocity required for a satellite to leave Earth's atmosphere.

  • Algebra/Free trial

    This course transitions students from the concrete world of arithmetic to the abstract world of variables and functions. We move beyond simple calculations to explore the relationships between quantities. The course focuses on solving and graphing various types of equations, including linear, quadratic, exponential, and logarithmic functions.

    Students will develop critical thinking skills by translating real-world scenarios into mathematical models. You will learn how to manipulate complex expressions, solve systems of equations, and understand the behavior of functions through their numerical, graphical, and analytical representations.
