The following lesson has as an objective to review the three main theories of evolution: Fixism, Lamarckism and Darwinism (Natural Selection). The presentation starts with some definitions of concepts that must have been acquired for now and may be helpful. It continues with a question in order to rise previous knowledge about evolution and how it happened. Then, the three theories are studied with examples and definitions. The one that has more content is Darwinism because the types of selections (stabilising, directional, disruptive and artificial) are shown with graphs. As closure, a small question is made about antibiotic resistance and a fun evaluated activity is proposed in order to evaluate the theories of evolution.

The goal of this worksheet is to hone critical skills such as reading comprehension and the analysis of information related to the behaviour and physical characteristics of human ancestors. Students will apply these skills to connect this knowledge with visual representations of skulls and various fossils. To achieve this, students will:

1. Begin by reading a text containing information about human fossils.
2. Observe images of human fossils and match each image with the appropriate description, providing justifications for their choices.
3. Proceed to construct a timeline that illustrates the evolution of humanity, with a specific focus on understanding the reasons for this evolution and its significance.
4. Answer open questions in order to understand the evolution of the human being, specifically why it happened and the importance of it.

In essence, this worksheet serves as a comprehensive exercise to help students explore the evolution of human beings by integrating textual and visual information, critically analysing it, and drawing connections to broader concepts.

Estimados colegas, 
Este recurso es una presentación Power Point de 11 diapositivas, está basada en el currículo nacional de Chile para Idioma Extranjero Inglés para III° Medio en la unidad: 'The importance of the evolution of languages'. Compara expresiones chilenas y con ayuda de los estudiantes podemos definirlas, luego se muestra adjunto un video de youtube de 'La gringa loca' que habla respecto de nuestros gestos culturales, y finalmente hay un texto de la cultura Británica y su 'body language'. 

Espero les sea útil.

A hug!

Noemiss :)

Rambus Memory: A High-Speed Innovation in Computer Memory

Rambus Dynamic Random-Access Memory (RDRAM) was developed in the 1990s by Rambus Inc. as a high-speed alternative to traditional DRAM. It was designed to provide faster data transfer rates, making it an ideal choice for high-performance computing applications. Initially adopted by Intel for use in its Pentium 4 processors, RDRAM gained recognition for its ability to handle large amounts of data efficiently.

Key Features of Rambus Memory

One of the defining characteristics of Rambus Memory is its ability to operate at much higher clock speeds than conventional SDRAM. RDRAM uses a unique architecture, featuring a narrow, high-speed data bus that allows for increased bandwidth. Unlike traditional memory modules, RDRAM employs a serial memory interface, which reduces signal interference and improves data integrity. Additionally, it utilizes advanced signaling techniques such as Rambus Signaling Logic (RSL) to enhance performance.
Another notable feature is its heat dissipation mechanism. Due to its high-speed operation, RDRAM generates more heat than standard memory modules. To address this, Rambus developed a heat spreader that helps maintain optimal operating temperatures. This feature made RDRAM more suitable for demanding applications, such as gaming and multimedia processing.

The Rise and Fall of RDRAM

Despite its technical advantages, Rambus Memory faced several challenges that limited its widespread adoption. One major drawback was its cost. RDRAM was significantly more expensive than its competitors, such as DDR (Double Data Rate) SDRAM, making it less attractive to budget-conscious consumers and manufacturers. The licensing fees imposed by Rambus Inc. also contributed to the high cost, discouraging widespread adoption.
Additionally, compatibility issues hindered RDRAM’s success. Intel initially supported the technology but later shifted its focus to DDR memory due to market demand and cost-effectiveness. As DDR technology improved and became more affordable, manufacturers and consumers gradually moved away from RDRAM. By the mid-2000s, Rambus Memory had largely disappeared from mainstream computing, replaced by DDR variants that offered similar performance at a lower cost.

Legacy and Impact of Rambus Memory

Although Rambus Memory is no longer widely used in consumer PCs, its influence on memory technology remains significant. The high-speed data transfer techniques pioneered by Rambus paved the way for modern memory innovations, including GDDR memory used in graphics cards and high-performance computing applications. Rambus Inc. continues to develop memory solutions, focusing on next-generation technologies such as high-bandwidth memory (HBM) and security solutions for data centers.

Conclusion

Rambus Memory was a groundbreaking innovation that set new standards for memory speed and efficiency. While it faced challenges that prevented it from becoming the dominant memory standard, its technological advancements continue to shape the evolution of modern computing. The lessons learned from RDRAM have influenced the development of faster and more efficient memory solutions, ensuring that Rambus Inc.’s legacy remains an integral part of the industry.

La evolución biológica es el conjunto de cambios en caracteres fenotípicos y genéticos de poblaciones biológicas a través de generaciones.​ Dicho proceso ha originado la diversidad de formas de vida que existen sobre la Tierra a partir de un antepasado común.​​
