| erwinjanssen.nl | Pelican | The website presents the Chinese remainder theorem, explaining how it solves systems of congruences and its relation to modular arithmetic. It discusses Euler's theorem and Euler's totient function, describing their applications in computing modular inverses and counting coprime integers. The site also elaborates on modular exponentiation and RSA cryptography, detailing the process of key generation, encryption, and decryption, highlighting the asymmetric nature of the RSA system based on prime number factorization. | Computer Science → Cryptography 27 | | |
| thezeroproject.nl | Zero Project Foundation | The website details an interdisciplinary research program exploring the origin and importance of zero, involving contributions from over 40 international scholars. The project examines zero’s development through historical, religious, philosophical, linguistic, artistic, and mathematical lenses, considering potential influences from non-European traditions and Western perspectives. Resources available include conference information, a book project titled ‘The Origin and Significance of Zero,’ a YouTube channel with a feature video, and information on the ExperTISE CENTER ON ZERO (XCZ) and donation options. | Philosophy → History of Philosophy 15 | youtube 486 conference 763 donation 5110 research 8967 book 11396 | |
| jinbijin.nl | Jinbi Jin | The site provides contact details, including an email address, for Jinbi Jin. It lists several pre-publications, including papers on étale cohomology, homogeneous division polynomials, and torsors over curves. Jinbi Jin has given research talks on topics such as étale cohomology, computability, classification, and multiplication on elliptic curves. | Mathematics → Algebra 20 | dissertation 126 seminar 299 | |
| manifesto-encryption.nl | manifesto-encryption.nl | The text consists of a long sequence of numbers and alphanumeric characters, repeated several times throughout the document. The repeated patterns include several numerical sequences and strings like '26577514' and '16189221325', interspersed with other characters and symbols. The overall impression is that of a deliberately constructed, yet nonsensical, text, with no immediately discernible purpose or message. | | number 199 character 449 pattern 2012 | |
| rubenvannieuwpoort.nl | Ruben van Nieuwpoort | The blog entries cover a wide range of subjects, including backpropagation, iterators, integer division, and approximate atavising. Ruben's notes delve into topics like multimedia generation from Python, alpha compositing, and the computation of Fibonacci numbers. He also explores advanced mathematical concepts such as Dirichlet's approximation theorem, Euler's gamma function, and the singular value decomposition. | Computer Science → Algorithms 31 | division 114 algorithm 141 | |
| ronvdven.nl | Ron | The website covers number systems, including the decimal, binary, and other systems such as octal and hexadecimal. The decimal number system, the most common system used in daily life, is based on the base ten and uses the digits 0 through 9. The binary number system is crucial for computers, which only operate on basic functions and therefore use two digits (0 and 1), with bits (binary digits) combined to represent value. | Science → Computer Science 2413 | bit 56 | |
| getalrijk.nl | N.V. | The website covers properties of numbers, such as the number of divisors of 168 and its factorization. It provides the decimal representations of numbers like √2, √3, e and π, with a focus on their irrational nature and the lack of a repeating pattern. The website offers the possibility to view the decimal digits of these numbers up to one million digits. | Mathematics → Algebra 20 | number 199 circle 235 | |
| wrweb.nl | Wim Romp | The website offers a WRwebForms tool that allows users to create websites using HTML text, forms, and reports. Additionally, there are applications for listing Greek verbs, checking if a number is prime, and generating prime numbers in graphical representations. The website also contains demonstrations of mathematical concepts such as the value of Pi, the Monte Carlo simulation, the 'Game of Life', perspective demonstrations, and games like 'Boter Kaas en Eieren', as well as fractal visualizations and a chess program. | | form 679 application 3377 | |
| natalino.busa.nl | Natalino Busa | The first entry presents a short, playful poem titled ‘Child’s eyes,’ focusing on observation and childlike wonder. The second entry provides an explanation of the Euler product formula in mathematics, detailing its application in calculating the probability of set-wise coprime integers. The final paragraph introduces the Euler–Mascheroni constant (γ), highlighting its unresolved status regarding whether it's rational or irrational, and its widespread appearance in mathematical equations. | | eye 107 formula 287 poetry 665 | |
