Hoe behandel je #klimaatverandering in je middelbare schoolklas? Het raakt aan wetenschap en onderzoek, maar kent ook economische en maatschappelijke aspecten. Echt vakoverstijgend dus.
Op 18 november organiseren we op de TU Delft een middag (16.00-20.00) voor middelbare school docenten! 🧵👇

Doing demonstrations in front of the entire (120 students) class is a great way to show everyone how the skills we taught them can be applied to very diverse problems. Also: it is just plain fun: look at this cute balloon!

and this wouldn't be a #Delft course if there wasn't some group that did anything bike related, such as this velocity measurement device. They video called into the room to demonstrate it. 🧵👇

This group thinking was: if we know how hard we throw a ball up in the air, we know how long it takes to come back down, we can use that as the basis of a clock: to measure time! Very satisfying to watch. 🧵👇

Others test the limits of the course to see how elaborate they can make a rather simple concept: by trying to keep this train exactly in position and knowing the voltage / speed relation of the train, this group can calculate the rotation of the big wheel the train sits on. 🧵👇

The assignment is to think up, design and build a device that can measure 'X of Y' where they get to pick X and Y themselves, for example these two groups measure 'wetness of soils' (using self made capacitive sensor) and 'strength of earth magnetic field' (self made Helmholtz coils) 🧵👇

Throwing a football through my lecture room @tudelfttnw.bsky.social. Final demonstrations of 2nd year course " #Design #Engingeering for #Physics Students 2" were a blast! Two hectic hours to test 28 measurement devices that students worked two months on designing and engineering. 🧵👇

instructie voor tweede jaars studenten aan het schrijven en vraag me toch af of deze referentie bekend is bij ze. Hoop het wel...

Today our @tudelfttnw.bsky.social Rob Mudde gave his last lecture before retiring in two days. Rob has taught freshman #physics course classic and relativistic mechanics for twenty years, even making time to keep teaching it when he was Vice-Rector Magnificus ! 🧵👇

Bij radar is de golflengte veel langer en kan je (dus) een zichtbare overgang al overbruggen! Met een simpele detector kan je zien dat de radar-golf voor een deel rechtdoor gaat! Deze opstelling kost maar een paar tientjes aan materiaal om (na) te maken! 🧵🛑

Wat deze studenten slim gebruiken is dat voor een radar-golf je parafine kan gebruiken zoals je glas kan gebruiken voor zichtbaar licht: als een lens of een prisma! Volgens 'klassieke theorie' botst een golfdeeltje op de overgang, natuurkundige noemen het 'volledige interne reflectie'. 🧵👇

Short courses are the more interactive sibling of regular conference sessions. They are aimed at capacity building in the broadest sense. In the past we've had courses as diverse as "science diplomacy", "Being a scientist and a parent", "publishing in Nature", "Working with OpenStreetMaps", etc.🧵👇

Deadline to submit sessions for #EGU26 is coming up (16 september!) This also means deadline to submit Short Courses.
#EGU26 might seem far away in May '26 in Vienna but we are already working on the program for it.
Did you now anyone can propose a short course? 🧵👇

This paper is part of special issue 'Hydrology in the 21st century: challenges in science, to policy and practice’. In the preface to the issue prof. @hayleyjfowler.bsky.social writes an overview of our work better than I could have done it :-). 🧵👇
![a screenshot from an article stating: Hut & Hall [15] propose a transformative approach to improve reproducibility, accessibility and equity in hydrological research. They introduce the MRDTACS principle: research should be reproducible by individuals earlier in their academic careers—and in less time—than it took the original researchers. The authors argue that embedding Open and FAIR practices, using reproducibility-friendly platforms (e.g. eWaterCycle, HydroShare, Google Colab) and teaching dependency management, containerization and modular workflows are essential to this goal. The paper provides practical strategies and tools to help early-career researchers and students reproduce and extend existing work efficiently. Through a case study on the eWaterCycle platform, the authors illustrate how technical design choices can reduce barriers, foster collaboration and improve education. Ultimately, they advocate for a cultural shift in hydrology where reproducibility and inclusivity are prioritized to accelerate innovation and empower the next generation of scientists.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:dy6rcvpaoyvx3lmz7mkbgr56/bafkreicn5g4jpqdex436xjbl5nefx5dp65jwthoswlamblrumnmjqv6lja@jpeg)

Only if it is easy to reproduce someone else their work will we do it before building further upon it. But how easy? We suggest: work should be reproducible by someone one career step 'younger' than you are: Moving Research Down the Academic Career Scale! 🧵👇

PS PS: While at the workshop, I also had an adventure with my old phd supervisor, crossing a very iffy bridge and finding a place called: "Rolfs Place!" I wrote about that in this (Dutch) column. The perks of an academic career :-). 🧵🛑
