HILBERT’S DREAM. “Hilbert’s idea is the culmination of two thousand years of mathematical tradition going back to Euclid’s axiomatic treatment of geometry, going back to Leibniz’s dream of a symbolic logic and Russell and Whitehead’s monumental Principia Mathematica. Hilbert’s dream was to once and for all clarify the methods of mathematical reasoning. Hilbert wanted to formulate a formal axiomatic system which would encompass all of mathematics.” https://lnkd.in/eRAK9d4N View in LinkedIn

ATOMIC MAGNETISM. “All of the atoms in an object act like several tiny magnets. In most materials, all of these moments face random directions and they all cancel each other out, and there is a net magnetization of 0, which means the object will not be a magnet. However, when all or most of these moments align in the same direction, the entire object has a net magnetization and creates a magnetic field around itself.” https://lnkd.in/eSxMNEaz.

INTERFERENCE. “Do all atoms have magnetic fields? The answer to this question is yes and no. All the electrons do produce a magnetic field as they spin and orbit the nucleus; however, in some atoms, two electrons spinning and orbiting in opposite directions pair up and the net magnetic moment of the atom is zero. The direction of spin and orbit of the electron determines the direction of the magnetic field.” https://lnkd.in/e-W4fms8 View in LinkedIn

ATOMIC VISUALS. “Visualization of the origin of magnetic forces by atomic resolution electron microscopy.” https://lnkd.in/e-Zc_Gwh View in LinkedIn

AN ATOMIC MAGNETISM FIRST. “The joint development team of Professor Shibata (the University of Tokyo), JEOL Ltd. and Monash University succeeded in directly observing an atomic magnetic field, the origin of magnets (magnetic force), for the first time in the world. The observation was conducted using the newly developed Magnetic-field-free Atomic-Resolution STEM (MARS).” https://lnkd.in/e-Zc_Gwh View in LinkedIn

DOUBLE SUCCESS. “This team had already succeeded in observing the electric field inside atoms for the first time in 2012. However, since the magnetic fields in atoms are extremely weak compared with electric fields, the technology to observe the magnetic fields had been unexplored since the development of electron microscopes.” https://lnkd.in/e-Zc_Gwh View in LinkedIn

HISTORIC. “This is an epoch-making achievement that will rewrite the history of microscope development.” https://lnkd.in/e-Zc_Gwh View in LinkedIn

ORIGIN OF MAGNETS. “Using this new lens, the team realized atomic observation of magnetic materials, which is not affected by the lens magnetic field. The team's next goal was to observe the magnetic fields of atoms, which are the origin of magnets (magnetic force), and they continued technological development to achieve the goal.” https://lnkd.in/e-Zc_Gwh View in LinkedIn

ATOMIC TINKERING. “Researchers modify the magnetic field of a single atom, demonstrating a potential way to store information in tiny devices of the future.” https://lnkd.in/ezxKQM_n View in LinkedIn
