A perfect number is a positive integer equal to the sum of its positive divisors excluding the number itself. For example, 6 is perfect because 1 + 2 + 3 = 6. Equivalently, a number is perfect if the sum of all its divisors including itself is twice the number. The earliest known discussion of perfect numbers was by Euclid, who proved that if 2^p - 1 is prime, then 2^(p-1)(2^p - 1) is perfect. Euler later proved all even perfect numbers have this form.

this is a presentation on a a number theory topic concerning primes, it discusses three topics, the sieve of Eratosthenes, the euclids proof that primes is infinite, and solving for tau (n) primes.
Lots of students find logarithm complicated and tricky.For them this slide may prove useful.This is the most easy way to learn logarithm.Best of luck!! :)

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. In number theory, a perfect number is a positive
integer that is equal to the sum of its positive divisors,
excluding the number itself. For instance, 6 has
divisors 1, 2 and 3 (excluding itself), and 1 + 2 + 3 =
6, so 6 is a perfect number.
The sum of divisors of a
number excluding the number
itself, is called aliquot
sum, so a perfect number is one that is equal to its
aliquot sum.
3. Equivalently, a perfect number is a number that is half
the the sum of all of its positive divisors including
itself; in symbols, σ1(n) = 2n where σ1 is the
sum-of-divisors function. For instance, 28 is perfect as 1
+ 2 + 4 + 7 + 14 + 28 = 56 = 2 × 28.
This definition is ancient, appearing as early as Euclid’s
Elements (VII.22) where it is called τέλειος
ἀριθμός (perfect, ideal, or complete number). Euclid also
proved a formation rule (IX.36) whereby is an even
perfect number whenever is a prime of the form for
prime - what is now called a Mersenne prime. Two
millennia later, Euler proved that all even perfect
numbers are of this form. This is known as the Euclid-
Euler Theorem.
