What It Is

ThatsMaths is a popular math blog. The text states that it supports a series of mathematics articles published in The Irish Times since July 19, 2012. It is not positioned as vocational training or an exam-prep course, but rather as a continuously updated collection of articles that presents mathematics to the general public as “beautiful, useful and fun.” Its goals include demystifying mathematics, showcasing the power of math, discussing technological applications, explaining recent developments, and exploring major unsolved problems.

Core Content and Format

Based on the captured content, the articles cover a very wide range of topics, including rainbow spectra, algorithms for calculating the date of Easter, the Riemann hypothesis, chaos theory, Lagrange points, quantum physics, digital signatures, weather forecasting, climate change, music and mathematics, and more. The content combines mathematical history, scientific figures, real-world technological applications, and introductions to foundational concepts. The main format is English blog reading, with updates available through the archive and subscriptions. There are no visible video courses, live classes, assignments, quizzes, or class-based learning arrangements.

Pricing and Certificates

The pages do not show paid courses, membership pricing, payment methods, or a purchase process, so its public content appears to be primarily free to read, though there is not enough information about its specific business model. The text also does not mention accreditation, completion certificates, or academic credits, so it is not suitable as a career-credential course.

Pros and Cons

Its strengths are its rich variety of topics, long update history, and effort to connect mathematics with real-world scenarios such as search, navigation, ATM encryption, medical imaging, weather forecasting, and financial communications. This can help reduce anxiety around mathematics. It also emphasizes the long-term interaction between pure and applied mathematics, making it useful for building scientific literacy. Its limitations are that it is not very course-like: there is no clear learning path, difficulty grading, practice feedback, or instructor Q&A. In addition, the all-English content may be a barrier for Chinese readers, and the captured text does not provide sufficient detail about the instructors or authors.

Who It’s For and Access in China

It is suitable for math enthusiasts, STEM students, teachers looking to expand lesson-preparation materials, and general readers who want to understand mathematical applications through short articles. It is not suitable for those who need systematic problem practice, exam-score improvement, certification, or structured training. Access from mainland China cannot be confirmed based on the text alone, so it is rated as unknown.
