Stikers: What is time made of?

Laboratorio de Divulgación Científica — 2025-10-29

This collection of popular science stickers celebrates heartbeats, music, the ephemeral and the long-lived, circadian rhythms, and the invisible measures that govern nature, our lives, and our time.

Tick-tac... who taught him to count to the clock

Santiago Vargas-Domínguez — 2025-10-29

Before the human being thought of dividing into hours and minutes, The Sun was already the master of time by marking the beginning of the day, the change of seasons, the rhythm of harvests and life itself. Study the Sun, as astronomers, peasants, ancestral and contemporary cultures have done, is also studying how we organize ourselves as a society. There is a deeper rhythm that beats in the universe, in our body and in the Earth itself. A rhythm that we can learn to listen to, driven by human curiosity and knowledge of physics.

The time of the science

Andrés Vélez Posada — 2025-10-29

Science is often presented as a futuristic enterprise driven by technological innovation, aspiring to overcome the limitations of the present and the past, as well as local particularities. However, conceiving the time of science as a competition toward grand synchronization obscures and simplifies the divergence of knowledge traditions, their social needs, their technological trajectories, and the multiple ways in which they experience the time of knowledge.

The world in the future: three possible scenarios

Jonathan Echeverry-Álvarez — 2025-10-29

De cara al futuro, enfrentamos la materialización de tres mundos posibles. El primero consiste en la distopía trágica cyberpunk. La humanidad y la naturaleza, con sus diversas formas de vida, al servicio del desarrollo tecnológico. El segundo escenario consiste en la utopía de la relación armónica entre naturaleza y la tecnología. La tecnología al servicio de la naturaleza y la sociedad. El tercer mundo podría ser un planeta sin humanos. Un mundo posthumano que reverdece para otras especies, la Tierra testiga de una especie fallida que no logró desarrollar mecanismos cooperativos para adaptarse a la velocidad de las circunstancias cambiantes.

What bees teach us to take care of future generations

Manuela Ruiz Veloza — 2025-10-29

Why do we always wonder about the future? It seems that we live in a society that lives in two times: improving today for tomorrow. Thus arise paradigms such as that of sustainable development, the idea of a development that meets today's needs without compromising the needs and demands of future generations. What if we explore the possibility of reaching agreements that limit certain aspects of development for the common good of future generations?

Crash! It's been shaking lately?

Ana Beatriz Acevedo — 2025-10-29

Educational comic about seismic disaster prevention and the measures that should be taken to improve community response to these types of natural threats.

The risk doesn't wait

Susana Galvis Bravo — 2025-10-29

Although Medellín is an innovative city, socio-spatial inequalities persist that expose its inhabitants to high-risk conditions. Sectors such as El Sinai, located on the banks of the Medellín River, face the constant threat of flooding. Historical dynamics of segregation, construction in unstable areas, and a limited presence of the State, force its inhabitants to live in a state of alert and develop risk self-management strategies. The academy proposes to study community risk management to value collective intelligence, accelerate reaction times and strengthen a dignified life.

Tribute to Michel Hermelin: It is possible to understand global warming by studying the history of the earth?

Laboratorio de Divulgación Científica de EAFIT — 2025-10-29

Tribute to Michel Hemelin (1937-2015), a professor and researcher at Universidad EAFIT from 1984 until his death. His academic work left a profound impact on the education and dissemination of geosciences in Colombia.

Editorial: Time as an inheritance and promise

Antonio Julio Copete Villa — 2025-10-29

Today, Universidad EAFIT not only celebrates its 65th anniversary; it also projects its legacy into concrete challenges: developing talent, leading with purpose, expanding knowledge, and connecting science, technology, and innovation with the world's regions. It does so knowing that time is both the scarcest and the most fertile resource.

Rural childhood, seed of change for Colombia

Ana María Parra Diez — 2025-10-29

Thinking about rural childhood in Colombia requires understanding social fabrics in transformation, which are interwoven with problems such as inequality, armed conflict and insufficient access to basic services, conditioning access to education. Currently, only 1.8% of the rural population has obtained a university degree. Promoting more comprehensive and contextualized learning experiences in rurality will help to compensate for the historical debt it has with the countryside.

Sustainability as a catalyst for public trust

Mery Patricia Tamayo-Plata — 2025-10-29

Sustainability is the protagonist of strategic analysis and discussions in all types of organizations. Strengthening public trust and business sustainability requires transparent communication with economic evidence of commitments and results in sustainability, which contributes to the overall improvement of the governance environment.

Future of regional finance in Colombia

José Miguel Arias Mejía — 2025-10-29

In Colombia, departments (each one of its thirty-two administrative divisions) are financed through their own resources and through transfers from the national central government. The differences in how each department obtains these resources mean that changes in the country's territorial fiscal policy can have very different impacts in each region. Going forward, it is crucial to strengthen equality between regions while encouraging their fiscal autonomy, so that public spending can be targeted to address the specific needs of the country's diverse geography.

From the hoe to the global market: The business alchemy of El Hueco

Natalia González Salazar — 2025-10-29

The commercial sector of "El Hueco" in downtown Medellín is a living laboratory of social innovation that invites us to rethink Latin American business history from its margins. The story of "El Hueco" proposes an alternative paradigm in organizational history by shifting the focus to grassroots actors and informal settings. By reclaiming social capital as an engine of development, it dismantles the belief that only large industrial elites generate economic growth.

"Time is gold" Or on how to save our most limited resource

Juan Carlos Luján Sáenz — 2025-10-29

La planeación y la optimización de procesos determinan en gran medida la eficiencia y la sostenibilidad de una organización. Para lograr una cadena de suministro óptima, es clave ajustar cada uno de sus eslabones para ahorrar tiempo y otros recursos valiosos. Desde la Ingeniería Industrial, la analítica computacional y la Ingeniería de Construcción se ofrecen soluciones para invertir el tiempo con mayor eficiencia.

Between questions and decisions to navigate business management

María Isabel García García — 2025-10-29

More than formulas or definitive keys, leadership must develop the ability to adapt to major changes and face uncertainty. These seven questions without a single answer are intended to help develop a strategic vision based on complexity, trust generation and adaptability. An invitation to explore, think and learn constantly to address the management of the future.

Companies as time machines: generation of public value and positive impact through sustainable business intentionality

Maria Alejandra González-Pérez — 2025-10-29

How do today's corporate actions resonate in the future? This article explores how companies that voluntarily orient their actions toward sustainability not only generate benefits in the present, but also create a lasting legacy that transcends generations. To do this, we address three concepts: time as both the setting and the protagonist; intentionality as the compass of business actions; and intergenerational responsibility as the ethical commitment that connects our present with a future we don't yet know, but which we are already building.

Wayuu Calendar

Maria Isabel Marín Cerón — 2025-10-29

The Wayuu Calendar is a graphic work that represents the cosmogony and natural cycles that guide the planting, fishing and livestock of the Wayuu people. In a context of climate change, this calendar promotes the dialogue of knowledge to concretise proposals for community climate governance. The work is under development within the framework of the research project "Sustainability Weavers in the Guajira Bio-Geo and culturally diverse: a scientific-community dialogue of the Ranchería River Basin."

Why can’t time be read in the sun anymore?

Catalina González-Tejada — 2025-10-29

“I thought it was a different time,” the Wayuu elders say as they look at the sky. Time, which flowed with the sun, the stars, the winds, and dreams, can no longer be read as it once was. Something is changing. This article describes the beginning of the collective process of constructing a Wayuu Climate Calendar through a dialogue between traditional and scientific knowledge.

Observe the time with this sundial

Nicolás Guarín-Zapata — 2025-10-29

Observe time with this sundial! Print the clock, follow the instructions, and experiment with this device to measure the passage of time, just as our ancestors did when they looked at the sky to understand the passage of time. Discover what a "gnomon" is and how careful observation of astronomical cycles facilitated the advancement of knowledge. This educational sundial is designed to work correctly in Colombia (at a latitude approximately six degrees north of the equator) and tells the time based on the shadow cast by the "gnomon" at this latitude.

Go through the history of planet Earth on a walk through EAFIT

Maria Isabel Marín-Cerón — 2025-10-29

Al Campus Georuta proposes an experiential tour that allows us to revisit the geological time of planet Earth while we walk through the EAFIT University campus. Through experiential learning tools such as this georoute, we promote the exploration of the environment and the interpretation of natural heritage, while generating dialogues that strengthen our awareness of the deep history of the Earth and the environmental challenges we face as a society.

Technology-mediated teaching and learning processes at EAFIT University

Luis Gerardo Pachón Ospina — 2025-10-29

La tecnología es clave para integrar conocimiento, docencia y aprendizaje. En la Universidad EAFIT, la plataforma EAFIT Interactiva (nuestro Sistema de Gestión del Aprendizaje), se ha consolidado como un entorno digital que redefine la experiencia de aprendizaje al impulsar la interacción, fomentar la flexibilidad y estimular la innovación. En este artículo exploramos su impacto transformador, los retos que implica su adopción y las historias reales de profesores que han logrado convertir sus cursos mediados por tecnología en vivencias significativas y memorables.

The testimony of the Cob

Matilda Andrea Lara-Viana — 2025-10-29

The testimony of the cob is an allegory about selective crops and the domestication of species in agriculture, which has influenced the development of civilizations and the conformation of the food base of today's society. Presenting the contrary perspectives of the farmer and the plants, it is criticized how this domestication process has occurred and the benefits or consequences it has brought with it.

To the rhythm of the beat: what does time mean in music?

Juan José Galindo Ramírez — 2025-10-29

En música, se denomina "tempo" a la velocidad e intención general de una composición, la cual se mide en pulsos por minuto o bpm (del inglés beats per minute). Pero el "tempo" es mucho más que una simple indicación de velocidad: es el ritmo que nos une, el latido invisible que nos invita a sincronizarnos con la obra y con quienes la interpretan. Si bien cada cultura, época y tradición musical tienen una manera particular de sentir y expresar el tiempo, este tiene una cualidad universal: nos permite pensar en el colectivo, en la comunidad que comparte la experiencia de la música.

Between the intimate and the common: the cinema as an experience of time

Paula Arredondo — 2025-10-29

What do a memory, a dream, and a film have in common? All three play with time, bending it, hiding it, transforming it. Cinema is a "time capsule" that allows us to inhabit other lives and feel emotions we didn't know we could feel. Cinema is light made memory. By embracing nonlinear narratives, the "seventh art" reflects how memory and desire fragment chronology, revealing that its true power lies in transforming each viewer's experience of inner time.

Between fossil fuels and new technologies: the energy dilemma in the future

Yerly Herrera — 2025-10-29

The energy transition is not just a technological shift, but also a cultural, political, and geological transformation that is just beginning. In Colombia, two narratives are clashing: one that prioritizes the climate emergency and another that emphasizes the country's energy and fiscal security. In any case, we must recognize that there is no completely "clean" energy, since each alternative to fossil fuels entails its own set of environmental impacts and material limitations that must be evaluated with scientific rigor and sustainability criteria.

Living in two times: the work of collective memory reconstruction in Colombia

Valeria Querubín — 2025-10-29

Why rebuild the memory of the armed conflict in Colombia? Without a deep understanding of the past, an assertive vision of the present and the future cannot be built. Memory in Colombia is established as a collective challenge where testimonies, judicial processes and reparation of victims are documented. The past still does not pass and memory can be affected by certain degradations. As citizens, it is up to us to build a collective future where new routes are traced with hope and empathy.
