My specialty is planetary science. Planetary science, which has developed on the basis of physics and astronomy, is expanding as a borderline science. Our knowledge of planetary systems has increased dramatically with the advent of probes into interplanetary space. New planetary systems have been discovered around other stars by the technological development of large observation equipment. Information science plays an important role in the development of these new fields. For example, the extraction of information from a weak signal sent by a remote probe and the separation of necessary information from a large data set are the results of advances in data processing technology.

You will apply yourselves to acquire techniques and knowledge for the science of information technology. It would be great if we could stand outside the field of information, look at things objectively, and set a new direction. Learning both the basics knowledge and the latest advancements in the relevant field will give you the depth of the specialty of your choice and help you come up with ideas for new technological developments. Please do not lose your curiosity, and let's nurture our willingness to move forward to a new world.
