An MIT professor spent his career teaching calculus, then went back and recorded five short videos explaining what all of it was actually for.
This is Gilbert Strang, MIT, "Highlights of Calculus." He's taught this material since 1962. These videos aren't a course. They're the summary he wished someone had given him first, before the years of formulas.
Calculus, at the core, is two functions watching each other. One tells you how fast the other one is changing. That's it. Position and velocity. Population and growth rate. Price and rate of change in price. Every calculus class buries that relationship under notation before ever saying it out loud.
Strang starts from the relationship itself, not the rules for finding it. He shows how a distance function and a speed function are just two views of the same motion, and how knowing one lets you reconstruct the other exactly.
Watch how he treats the derivative less like an operation to memorize and more like a question: given how something is changing right now, what does that tell you about where it's going.
Calculus was never really about solving for x. It was a way of catching change in the act, and Strang spends five videos handing that idea back to anyone school buried it under.
At the closing ceremony, ACEP’s Executive Director, Mr. @benboakye , noted that the global energy transition is no longer only about climate action, but increasingly about who controls the industries, critical minerals, technologies, and power systems of the future.
For Africa, this means climate conversations must also reflect the economic and geopolitical realities shaping the global energy transition, while positioning the continent to secure greater value and influence within the emerging energy order.
Beyond the sessions, the Academy continues to build a growing network of African climate leaders committed to driving accountability, influencing policy, and shaping a climate-resilient future for the continent.
Over four days, the ACEP team, led by Dr. Charles G. Ofori, partnered with the University of Cape Coast and Takoradi Technical University to engage students in interactive workshops on Energy Transition in Africa: Balancing Development and Justice and Natural Gas Management and Commercialisation, facilitated by Dr. Joseph Willie Amoah.
Students explored Africa's evolving energy transition, challenged common misconceptions, and discovered how their diverse fields of study can contribute to a just, sustainable, and industrialised energy future.
As Africa navigates the energy transition, young people have a critical role to play and we're committed to equipping them with the knowledge and skills to lead the way.
Thank you to the University of Cape Coast and Takoradi Technical University for partnering with us to shape the next generation of energy leaders.

ACEP, as a leading voice in Africa’s energy and extractives governance space, engaged key institutions in Sierra Leone’s mining sector, including government agencies, accountability actors, and the media.
The discussions focused on tackling illicit financial flows in the industrial minerals sector, with emphasis on dimension stones, improving production remote monitoring technology, and expanding value addition for national development.
The engagement concluded with a concrete blueprint to strengthen governance of the dimension stone sector and boost domestic revenue mobilisation for Sierra Leone’s socio-economic growth.

ACEP and SolarTaxi Ghana have officially signed an MoU to launch the Green Energy Technology Capacity Development Program (GET-CADEP)—a transformative initiative designed to equip young Ghanaian women with practical green skills for the future of work to begin next year.
As the world accelerates toward cleaner, technology-driven energy systems, green skills have become essential for competitiveness, inclusion, and sustainable development.
Through the GET-CADEP initiative, we are bridging the gap between policy and industry, expanding access to green jobs, and empowering women to thrive in Ghana’s evolving renewable energy landscape.
A just, inclusive energy transition depends on equipping the next generation with the right skills and together, we’re opening doors to green jobs and shaping the future of renewable energy.

Over 54% of Ghanaian households still rely on wood-based fuels, fueling deforestation, emissions, and indoor air pollution. Ethanol stoves offer a cleaner, safer alternative, but we need bold innovation to make them truly accessible.
ACEP invites young innovators to design ethanol-based cookstoves that are: fuel-efficient, affordable, safe, and locally adaptable.
Interested parties may apply individually or in teams (up to five members). Selected winners will receive expert mentorship and national visibility for their innovation, and will share in a total grant funding pool of up to $15,000. The grant and mentorship are intended to help improve the blueprint and produce a sample cookstove.
📅 Deadline for submissions: 27th July, 2025
