All science is materialistic

[Jehanne]

Matter and mass are not equivalent terms.

In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.[1] All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume.
