SPS Members, You Are All Heirs of Fourier! [From the Editor]

My three years of service as the editor-in-chief (EIC) of Signal Processing Magazine ( SPM ) are now coming to a close. During the past three years, many of us were deeply affected by serious political, social, and environmental events such as the war in Ukraine; protests for freedom in Iran; coups d’état in Africa; the COVID-19 pandemic; seisms in Turkey, Syria, and Morocco; huge floods in Libya and India; gigantic fires in North America and Southern Europe; and an avalanche of stones in the Alps, to name a few. In such a context, I believe that the IEEE slogan, “Advancing Technology for Humanity,” is incredibly relevant and timely. It also must be viewed in a wider sense, including the preservation of Earth and sustainable development. In point of fact, what would become of humanity without Earth? I believe that we must always have this in mind when contemplating our future projects, asking for funding, and while teaching.
