Support De Leidsche Flesch and celebrate 100 years of science
Did you know that Albert Einstein conducted research at Leiden University? Or that the first capacitor – a now indispensable technology – was invented here, in the form of a Leyden jar (Leidsche Flesch). And that from 1908 the Kamerlingh Onnes building was known as the coldest point on earth because the eponymous physicist liquefied helium here by cooling it to -272.20 °C?
Besides Einstein, famous scientists like Niels Bohr, Snellius and Paul Ehrenfest carried out research in Leiden. But even today, both our programmes and our research rank highly in the Netherlands and the whole scientific world.
Time to celebrate the 100th anniversary of our study association for physics, astronomy, mathematics and computer science!
Why do we need your contribution?
We want to introduce as many people as possible, young and old, to all that is unique about science. To do so, we want to mount exhibitions and hold an unforgettable symposium at a fantastic location with exceptional speakers, and for science in Leiden to leave a lasting impression. Then everyone can experience how special the exact sciences are in Leiden – and what they have already achieved. But we need money to realise our plans.
Please join us, so we can achieve the following goals:
- € 500: exhibition on mathematics in nature during Museum Night 2022
- € 750: additions to exhibitions at Museum Boerhaave
- € 1000: unveiling of capacitor wall formula
- € 3000: attractive location for our science symposium
- € 5000: famous speaker for our science symposium
Donate to De Leidsche Flesch’s special anniversary
In exchange for your donation, you can receive several rewards. To see what these rewards are, take a look at the right side of the page. These rewards can be stacked, so a donation of €19.23 for example, will earn you both a goodie and an honourable mention on the website.
To find out more about our initiatives, see all milestones in the menu at the top.
Exclusive experience!
The donors who sponsor the most will receive a gift in the shape of an exclusive experience! They can suggest a subject and we will find a professor to give a lecture on this. We will also arrange a meet and greet with said professor before or after the lecture. The lecture itself will be open to students, staff and alumni too.
Only the biggest donors can earn this unique gift. If you are one of them, we’ll contact you at the end of the sponsorship campaign.
Thank you for your support!

Who are we?
We are the Lustrum committee of De Leidsche Flesch, a study association for mathematics, computer science, physics and astronomy at Leiden University. In the 2022-2023 academic year, we are celebrating our 100th anniversary and we want to express not only what a friendly association it is but also how much scientific value it has.
The Lustrum committee consists of five students and one alumnus from different backgrounds, who have volunteered to fill the year with various activities: from a party on a boat to a science symposium, from additions to exhibitions to a festival. For more information about us see defles.ch/lustrum.
Do you have any questions about our crowdfunding or the lustrum in general? Feel free to contact us!
You can reach us at lustrum@deleidscheflesch.nl.
Within our degree programmes there is a lot of knowledge that is a good fit for the museums in Leiden. But at present there is no way to share that knowledge. Therefore, on Museum Night on 28 May 2022, we want to cooperate with several museums to provide additions to their existing exhibitions.
We are going to mount an exhibition in the Hortus Botanicus on mathematics in nature. There are many mathematical patterns in nature, but where do they come from? We are going to develop this entire exhibition ourselves and the crowdfunding will contribute to the development costs.
In addition, we have a partnership with museums in Leiden, including Museum Boerhaave, where we provide extra information about objects in their exhibitions. We explain how these objects are seen from our scientific perspective, and a QR code alongside them leads to our site, where more information is provided about the object. We are looking for a science communication expert to write these texts and a translator to translate them into English; the crowdfunding will cover some of these costs.
Several wall formulas can be found in Leiden. These were placed by scientists from the Leiden University Institute of Physics. The last formula in the series will bear the name of our society: the Leyden jar. The Leyden jar was the first capacitor in the world, an object that can store electricity. A mural will be made in the centre of Leiden with the formula of this capacitor. This formula will join the existing collection of wall formulas on muurformules.nl and can be used in the years to come to tell this part of Leiden’s history in guided tours for not only tourists but also schools.
We are keeping the location of the formula to ourselves for the time being, but we hope to be able to reveal it to the city on Friday 9 September. As this formula completes the Leiden Wall Formulas project, we would like to draw attention to the unveiling. We will focus on both the residents of Leiden and the local media. Donations will help provide the resources needed to ensure a big turnout for the unveiling of the wall formula.

4. Science symposium
An anniversary of a study association should always include a symposium about the degree programmes. For our 100th anniversary we want to do this in style. On Wednesday 15 February we will hold a day-long symposium with lectures on mathematics, computer science, physics and astronomy.
5. Famous speaker at the science symposium
To ensure a big turnout for the symposium, we are looking for a fantastic location in Leiden and famous speakers. The crowdfunding will contribute to the extra costs of this location and speakers. We hope to attract as many students, university staff and other visitors as possible to our symposium.
