If my research group had a logo, it would be this picture here: an ouroboros, where you see the micro-world on the left -- the world of the quantum -- and on the right the large-scale universe of planets, stars and galaxies.
如果我的研究小组要选择个徽标的话，将会是这张图片： 一条首尾相连的环形衔尾蛇，在左边是微观世界 - 即量子世界 - 而在右边是 宏观的宇宙包括行星，恒星和星系。
