Oort constants
Located half an hour by car north of The Hague , in Leiden have a kind of nice fixation with the walls and with the possibility of using them as a canvas , giving them a second life and, incidentally, beautifying the city.
To understand it, we have to go back to 1992, the year in which Poems and Walls , an initiative of the Tegen-Bleed Foundation that filled the walls of Leiden with poems and the same one that has inspired physicists Sense Jan van der Molen and Ivo van Vulpen to do the same, but with the formulas of your field of work.
Einstein's field equations
The creators of this strange artistic pairing assume that it is possible feel “the beauty of a formula, even without fully understanding it” , they write on their website, Leiden Wall Formulas. "Like when we feel the weight of the words of foreign poetry, even though we can't read it."
The design and subsequent painting of the drawings of each formula have been carried out by the artists of the Tegen-Bleed. They started in November 2015 and have already six , all of them created by physical who were linked at some point in their lives with the **Leiden University.**
The Lorentz Contraction
So they can be seen the Einstein field equations of the theory of relativity . The legendary scientist was a professor at this university and lived in the city at different times in his life. He did not deduce his famous theory there, but **his third component of it (the cosmological constant ‘Λ’)** was born from the discussions he had with Willem de Sitter, also a professor at the institution.
In addition, you can also see the interpretation of Snell's Law, Lorentz Force, Oort Constants, Lorentz and Spin Contraction by Samuel Goudsmit and George Uhlenbeck.
Snell's Law
Finding them is easy if you use the map published on their website or the audio guide that they also provide. information about physics and about the inventor of the formula and its relationship with the city . At the moment, a small handicap in sight: it is only available in Dutch and soon in German. English and other languages will be added throughout 2018.
