Nobel Peace Prize Forum 2025 | Ballots not Bullets: The Democratic Pathway to Peace (TV webcast)
2025-12-11 15:00 - 17:00 | Oslo, Oslo, Norway
The pathway to peace is not an easy one, it is secured through freedoms that are granted and protected by a government that is fairly and freely elected by the people.
The 2025 laureate, María Corina Machado, has worked tirelessly for free and fair democratic elections – the very foundations of a peaceful society – in Venezuela.  Democracy is a precondition for lasting peace. However, we live in a world where democracy is in retreat, where more and more authoritarian regimes are challenging norms and resorting to violence. With Venezuela as an example, the Forum will focus on democracy as the foundation for peace, and how the transition from authoritarianism to democracy can pave the way for peace in different parts of the world.

Eindejaars #Plantenjacht 2025
2025-12-25 - 2026-01-03
We weten maar weinig van planten die midden in de winter bloeien, daarom brengt Tuintelling ze samen met jou in kaart tijdens de Eindejaars plantenjacht. Jaag je mee?
Midden in de winter zijn er verrassend veel bloeiende plantensoorten te vinden. Sommige kunnen het hele jaar door bloeien, andere weten hun najaarsbloei te rekken wanneer er geen serieuze nachtvorst is. En als het weer meezit dan komen de voorjaarsbloeiers al uit op zonnige en beschutte plekken. Kies een moment in de telperiode. Noteer gedurende één uur alle wilde en verwilderde planten die in je tuin in bloei staan (Tuinplanten tellen niet mee). De bloemen kunnen trouwens heel klein zijn, dus het is soms echt even zoeken. Mocht het in deze periode tijdelijk heel koud zijn, waardoor er geen planten bloeien, kijk dan nog een keer als het minder koud is. Planten kunnen soms heel snel weer in bloei staan. Geef alleen bloeiende planten door. Je hoeft geen aantallen te noteren. Deel je vondsten op de Facebook-pagina van FLORON of van jezelf. Zo maak je andere natuurliefhebbers enthousiast om ook mee te doen. Welke planten zagen we het vaakst in bloei? Wat zijn de verschillen met vorige jaren? Welke trends zijn er te zien? De belangrijkste resultaten worden gepubliceerd na de telling op deze pagina. Heb je meegeteld? Dan ontvang je via e-mail een seintje als de resultaten klaar staan. De zoekkaart van FLORON helpt je om de 15 meest voorkomende winterbloeiers te herkennen.

Royal Institution Christmas Lectures 2025 (BBC Four / BBC iPlayer)
2025-12-28 20:00 - 2025-12-30 21:00 | The Royal Institution of Great Britain, 21 Albemarle Street, London, Verenigd Koninkrijk
The Royal Institution Christmas Lectures are a series of lectures on a single scientific topic each, which have been held at the Royal Institution in London each year.
The lectures present subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday conceived and initiated the Christmas Lecture series in 1825, at a time when organised education for young people was scarce. Many of the Christmas Lectures were published. On the 200-year anniversary of the Royal Institution Christmas Lectures, the 2025 Lectures will see leading space scientist Dame Dr Maggie Aderin-Pocock take audiences on an epic voyage through time and space. Joined by a host of very special guests – from astronauts to history-making astronomers – Maggie will explore the extraordinary breakthroughs that have revolutionised our understanding of the universe, enabling us to see ever further into space, and ever further back in time. Maggie helped develop the James Webb Telescope, the most powerful space telescope ever created – which launched on Christmas day 2021 before travelling a million miles to begin its orbit of the sun. Unpacking James Webb’s latest breathtaking images, Maggie will reveal how this “time-travelling” telescope is now rewriting the story of the Big Bang and allowing us to witness the birth of the first stars and galaxies that followed.
As NASA prepares to return humans to the moon for the first time since 1972, Maggie will investigate how manned spaceflight has transformed our relationship with our nearest neighbour – and with our home planet. And, delving further back in time, she’ll explore how the night sky has always held a fascination for humanity – investigating what the moon and stars meant to ancient societies across the world. Maggie will also explain how the latest space technologies – from probes and orbiters to the most recent Mars rovers – are shedding astonishing new light on the planets in our solar system. And we’ll discover why in 2025 we’re on the cusp of even more remarkable discoveries about our universe. She will reveal just how far our understanding of space has come in the two centuries the Ri CHRISTMAS LECTURES have been around – looking back on previous Lectures on astronomy – from the first of these in 1826 to the 1977 lectures hosted by famed astronomer Carl Sagan, when the only known planets at that time were the eight in our solar system (thought to be nine at the time). Maggie will also scour the Royal Institution archives to uncover some of the original props from these historic lectures, plus she’ll recreate – and supersize – some the most memorable demos from space lectures past. In this iconic anniversary year these lectures will be a true celebration – of our universe and of the astounding human endeavours that are allowing us to solve its mysteries.
