Dark Matter
The two greatest mysteries of the universe
Dark matter is an unknown substance, unevenly distributed throughout the universe and invisible to the human eye. We may not be able to see it, but its existence has been inferred from a multitude of indirect evidence, the first of which was the motion of galaxies noted in the 1930s. Unfortunately, we still have absolutely no idea what it is. We do however know what it isn’t. From observational data we know that dark matter is not any type of matter made from atoms, and that it isn’t any known type of celestial body or elementary particle. The remaining option, and the mainstream theory, is that it may be some form as yet undiscovered heavy elementary particle. .video {width: 560px;margin:0 40px;} Video.

AY 2013 Spring Undergraduate and Graduate Commencements Held (General Affairs Group)
The University of Tokyo AY 2013 Spring Undergraduate Commencement was held at Ariake Coliseum on Tuesday, March 25th, 2014. For this year’s Undergraduate Commencement, students from all Faculties gathered at the venue together with their family members. The Commencement was attended by approximately 2,500 graduates (out of 3,084 graduates in total) and about 2,900 guests (students’ relatives and others). The Graduate Commencement, meanwhile, was held at the same venue on the previous day (Monday, March 24th). Approximately 2,400 students who completed the higher degree courses (out of 2,752 Master’s degree students, 851 Doctoral degree students, and 308 professional degree students in total), as well as about 2,500 guests (their relatives and others) attended the ceremony.

The spontaneous formation of complex systems
A water molecule has a very simple structure—one oxygen atom and two hydrogen atoms bonded together at an angle. Yet when placed under certain conditions, water molecules form beautiful hexagonal crystals. Curiously, they naturally take this form without any outside effort. This spontaneous formation of complex systems from simple components is called self-assembly. The growth of seeds into plants and the formation of organized human society can also be seen as self-assembly in a broad sense, and the concept is attracting attention from many disciplines. In the world of chemistry as well, interest in self-assembly is growing. Through coordination bonding, hydrogen bonding, hydrophobic interactions, and other weak bonding, simple, small molecules assemble and with relative ease form l...
