The Flexner Report is a book-length landmark report of medical education in the United States and Canada, written by Abraham Flexner and published in 1910 under the aegis of the Carnegie Foundation. Many aspects of the present-day American medical profession stem from the Flexner Report and its aftermath. The Report called on American medical schools […]
Mathew Baker was one of the most renowned Tudor shipwrights, and the first to put the practice of shipbuilding down on paper. The first list of ‘Master Shipwrights’ appointed ‘by Patent’ by Henry VIII of England included ‘John Smyth, Robert Holborn, Richard Bull and James Baker,’ in 1537. James Baker was responsible for many of the designs and the construction of King Henry’s
The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity. For example, the space occupied or contained by a material (solid, liquid, gas, or plasma) or 3D form. Volume is frequently mathematically measured using the SI-derived unit, the cubic metre. The volume of a container is commonly believed to
An algorithm is a well-defined, step-by-step procedure or set of rules for solving a specific problem or performing a computation. Algorithms are fundamental to computer science, mathematics, and data processing, providing structured methods to transform inputs into desired outputs efficiently and reliably. They can be expressed in natural language, pseudocode, flowcharts, or programming languages. Algorithms
A lava lamp is a decorative lamp, invented in 1963 by British entrepreneur Edward Craven Walker, the founder of the lighting company Mathmos. The lamp consists of a bolus of a special coloured wax mixture inside a glass vessel, the remainder of which contains clear or translucent liquid. The vessel is placed on a box containing an incandescent light bulb whose heat
Cryptography is the science and engineering of securing communication through mathematical techniques that ensure confidentiality, integrity, authentication, and non-repudiation. At its core, cryptography transforms readable information (plaintext) into an unintelligible form (ciphertext) using an algorithm and a key, such that only authorized parties can reverse the transformation. It is a discipline situated at the intersection
A Euclidean vector is a mathematical object representing both magnitude (length) and direction within Euclidean space. It is an element of a Euclidean vector space—a finite-dimensional vector space equipped with an inner product that defines lengths and angles. Euclidean vectors formalize geometric intuition: arrows in space that can be added, scaled, and compared. 🧭 Geometric
A negative number is a real number that is less than zero and is typically represented with a minus sign (−) before the number. Negative numbers extend the concept of integers and real numbers into values below zero, enabling the representation of debt, temperatures below freezing, elevations below sea level, and losses in various contexts.
An integer is a whole number that can be positive, negative, or zero, without any fractional or decimal component. Integers are a fundamental concept in mathematics, forming the set of numbers denoted by ℤ, derived from the German word Zahlen, meaning “numbers.” They are widely used in counting, ordering, algebra, computer science, and number theory.
A polynomial is a mathematical expression consisting of variables (also called indeterminates), coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication. 🔢 The word comes from the Greek poly (“many”) and Latin nomial (“term”), literally meaning “many terms.” Polynomial modeling remains the foundational tool for everything from machine learning regression to aerospace trajectory
