Atomic

Quotes attributed to the German theoretical physicist Arnold Sommerfeld are being shared and discussed on social media under science and philosophy hashtags. Sommerfeld, a pioneer of atomic theory and quantum physics mentor to several Nobel laureates, remains a popular figure for reflections on science. The engagement is modest, indicating a niche audience of physics enthusiasts.

Physicists report a tabletop experiment using ultracold atoms to simulate the creation of particles, mimicking processes that normally occur in extreme environments such as the early universe or strong quantum fields. By controlling cold atomic gases, researchers can model quantum field behavior in the lab, offering a new way to test ideas that are otherwise out of reach of direct experiments.

Fifth Wall co-founder Brendan Wallace spoke with Forbes about Atoms, the new proptech venture launched by former Uber chief executive Travis Kalanick. Wallace discussed Kalanick's return to technology, how Atoms fits into the property technology landscape, and his views on the future of real estate innovation and investment.

Gizmodo explains the classic physics demonstration in which a pickle plugged into household current glows and sparks. Sodium ions in the brine conduct electricity, and excited sodium atoms emit the same yellow-orange light as street lamps. The article walks through the science of the eerie glow, reviving a popular classroom and party-trick experiment.

Nature is revisiting the 1966 Nobel Prize in Physics, awarded for work on the structure of atoms and radiation. The prize went to Alfred Kastler of France for the development of optical methods for studying atomic energy levels, research that relied on collaboration between theorists and experimentalists and opened new paths in spectroscopy and quantum physics.

The International Atomic Energy Agency has reported Iran to the United Nations Security Council, according to the Arms Control Association. The referral is a significant escalation in international oversight of Iran's nuclear programme, giving the Security Council a formal role in addressing Iran's compliance with nuclear safeguards obligations. Such a move could open the way to renewed diplomatic pressure or further measures against Tehran.

The 1986 Nobel Prize in Physics is being revisited for honouring the breakthrough that let scientists see individual atoms using electrons. The work established electron-based imaging as a foundation of modern microscopy and materials science, allowing researchers to observe atomic structure directly rather than inferring it.

The Financial Times argues that artificial intelligence development should not be likened to the Manhattan Project, the secret US programme that built the first atomic bomb. The comparison has circulated as governments and companies frame AI as a national-security priority. The piece pushes back against the framing, suggesting the analogy distorts public understanding of what AI research is and how it is being pursued.

NDTV has published a report titled 'Weapons Of Peace' examining the size of India's nuclear arsenal, setting out estimates of how many atomic bombs the country possesses. The piece comes amid ongoing global attention to nuclear stockpiles and regional security in South Asia.

New evidence indicates Nazi Germany was even farther from building an atomic bomb than historians previously believed, according to a report by The Debrief. The findings add to long-running debate over how advanced the German nuclear weapons programme actually was during the Second World War, and how close it came to developing a nuclear device before the war ended.

Iran's nuclear program remains clouded in uncertainty as the country's leadership reportedly debates abandoning the Non-Proliferation Treaty. The debate over withdrawal raises concerns among international observers about expanded nuclear activity and a further loss of transparency over Tehran's atomic facilities, at a time when access and verification are already limited.

A physics report examines research into the shapes of exotic nuclei, the short-lived atomic nuclei far from stability that scientists study in the lab. Understanding whether these nuclei are spherical, elongated or deformed helps refine models of nuclear structure and the forces binding protons and neutrons together.
