On Friday, March 13th, SPiN (Students Physics in the Netherlands) is organizing the national Master‘s Day for all students who study (applied) physics or astronomy and want to pursue a master‘s degree after their bachelor’s. At the Master‘s Day, you will be introduced to many different Master‘s programs from different Universities within the Netherlands. Many study programs in the Netherlands will be present, all in one location, meaning you won’t have to travel all around the Netherlands.

On the day itself, you can walk around the information market and talk with various study programs and possibly one company.

This year the Master‘s Day will be organised in Leiden in the Atrium of the Gorlaeus Building, Einsteinweg 55, 2333 CC. The day starts at 14:00 and it ends at 18:00.

Joining this event is free and registration is not necessary: you can walk in and join the event. However if you want updates on when to sign up for lectures you can sign up here: https://forms.gle/m4KkivHioRnfsJUd8 (as long as there is place in the lecture room, signing up is not necessary!).

Rule 1 of the Yearbook Committee, you don’t talk about the Yearbook Committee.
Rule 2 of the Yearbook Committee, you don’t talk about the Yearbook Committee.
But for this one time we’ll have to make an exception, because the long awaited Yearbook Committee finally has a theme to unveil. On the 10th of March, at 17:30 in BE 0.06, the Yearbook Committee will have their Yearbook Theme Announcement Drinks, also known as the YeBoTheAnDri. Be sure to join! And don’t forget, you didn’t hear anything about the Yearbook Committee, you don’t know anything about a Theme Announcement Drinks, so there’s no reason to talk about the Yearbook Committee.

That’s why we’re giving you the chance to participate. On the 25th of March from 13:15 to 16:15, you can participate in BW0.06! Will you join?

The NSE is the National Student Survey, which could be thought of as a customer satisfaction survey for all students in the Netherlands. Its results are used in the improvement of education, but are also used as a means to make national comparisons between universities, for example through the Keuzegids.

For these two reasons, it is important that we collect representative results and that the largest possible group of students have their voices heard. By the way, in case you are interested or ask a fellow student about it: on this page you can look up the results of the past year for your program.
*This year the NSE can be filled out until March 8 using a link that every student received via uMail.*

*Did you fill out the NSE? Then be sure to come and get a free chocolate in the FK!*

This summer break, from the *24th* to *28th* of *August*, we will be embarking on our *Sailing Week*! For a fee of at most *€130,-*, you can join us for 5 days of sailing. We are both looking for people with sailing experience who can help manage the boats, but also for people without (sufficient) sailing experience, who want to come along for the ride!
