Opposite Number

A recently unveiled experiment at CERN confirms that Einstein was right; antimatter reacts to natural forces the same way as matter. It's a logical hypothesis, but scientists...

Scientists at Brookhaven National Laboratory have used two-dimensional condensed matter physics to understand the quark interactions in neutron stars, simplifying the study of these densest cosmic entities. This work helps to describe low-energy excitations in dense nuclear matter and could unveil n

Partial functions are often considered harmful, and we recommend developers use total functions instead. In this post, we'll explore what the true opposite of a partial function is.

These odd values were long dismissed as bookkeeping. Now physicists are proving that they describe the hidden shape of nature

Two congruent angles are simply pairs of angles with equal measures. You can find congruent angles examples in hundreds of everyday objects.

The near-perfect roundness deepens the mystery behind how the universe came to be filled with matter as opposed to antimatter.

Mathematical induction (aka Principle of Mathematical Induction) is a powerful technique in mathematics used to prove statements that are true for infinitely many natural numbers. Formally, the principle of mathematical induction is stated as: For \(n \in \mathbb{N}\), let \(P(n)\) be a predicate. If Base Case: \(P(0)\) is true, and Inductive Step: Assuming \(P(n)\) is true show \(P(n) \implies P(n + 1)\) holds.…
