One Glass, Thousands of Atoms Drifting Through the World's Oceans

A 250 mL glass of water contains about 2.5 × 10^25 atoms, while all Earth's oceans hold roughly 5.3 × 10^21 glasses of water; thus that glass contains about 4,700 times more atoms than there are ocean glasses. If you marked every atom and mixed it back into the seas, thousands of those marked atoms would eventually appear in any new glass drawn anywhere on Earth, illustrating how unimaginably small atoms are relative to macroscopic objects and why biological molecules require enormous numbers of atoms to behave reliably.

Cosmic energy lives on: Tyson on burial vs cremation

Astrophysicist Neil deGrasse Tyson explains in a StarTalk clip that burying a body lets energy cycle back into the Earth through decomposition and the food web, while cremation releases energy as heat that radiates into space, with the idea that you’re transforming rather than vanishing and some atoms may even voyage to distant stars.

Death as Reorganization: Physics Says You Don’t Vanish

Physics says when you die, your atoms don’t vanish; they disperse into soil, air and other living systems, while the pattern that defined you—the brain’s arrangement of those atoms—unravels as energy flow ceases. Memories and personality are tied to this arrangement, not to any single atom, so personal identity ends even as matter persists and recycles throughout the universe.

Travis Kalanick unveils Atoms, a wheelbase platform for specialized industrial robots

Travis Kalanick launches Atoms as a platform to power specialized industrial robots (not humanoids), plans to acquire Pronto and fold in his CloudKitchens unit, and targets industries like food service, mining, and transport, while publishing a lengthy manifesto about a coming “Golden Age” of autonomous manufacturing.

MIT Develops Tabletop Technique to Visualize Atomic Nuclei

MIT researchers developed a novel molecule-based technique using radium monofluoride to probe the interior of atoms, allowing electrons to briefly enter the nucleus and reveal its internal structure, which could shed light on fundamental questions about matter and antimatter asymmetry in the universe.

MIT Physicists Develop New Electron-Based Technique to Explore Atomic Nuclei

MIT physicists developed a tabletop technique using molecules to study the interior of an atom's nucleus by tracking electron energy shifts, providing a new way to probe nuclear structure and fundamental symmetries, especially in radium, which could shed light on matter-antimatter imbalance in the universe.

Physicist Explains How Atoms Form and Make Up Everything

Atoms formed primarily from hydrogen and helium shortly after the Big Bang as the universe cooled, with heavier atoms created later in stars through fusion and in supernova explosions, while dark matter remains a mystery.

The Evolution of the Atom and Its Benefits for Science

The article discusses how the meaning of the word 'atom' has evolved from its original Greek definition of 'indivisible' to our current understanding of atoms as composed of smaller particles like protons, neutrons, and electrons, highlighting the progression of scientific discovery and the importance of naming conventions in science.

Why Can't We Walk Through Walls Despite Atoms Being Mostly Empty Space?

Despite atoms being mostly empty space, we can't walk through walls due to electromagnetic repulsion and the Pauli exclusion principle, which prevent atoms from overlapping, making solid objects feel solid. Quantum tunneling allows for an infinitesimal chance of passing through barriers, but it's practically impossible for macroscopic objects.

Physicist Explains the Origin of Atoms

Atoms, primarily hydrogen and helium, formed shortly after the Big Bang as the universe cooled, with heavier atoms created later in stars through fusion and in supernova explosions, which distribute these elements across the universe.

Physicist Explains How Atoms Form and Make Up Everything

Atoms, the building blocks of everything around us, formed mainly from hydrogen and helium shortly after the Big Bang, with heavier atoms created later in stars through nuclear fusion and supernova explosions. Most of the universe's matter is hydrogen and helium, while heavier elements like carbon and oxygen are produced in stellar processes.

Scientists Edge Closer to Confirming a Fifth Force of Nature

Physicists have found potential evidence for a fifth fundamental force inside atoms, based on deviations in atomic transition measurements in calcium isotopes, which could suggest the existence of a new force mediated by a Yukawa particle, although further research is needed to confirm this discovery.

Quantum Forces: Why Matter Feels Solid

The solidity of matter, despite atoms being mostly empty space, is explained by quantum mechanics, particularly the Pauli Exclusion Principle. This principle states that no two fermions, such as electrons, can occupy the same quantum state simultaneously, preventing atoms from passing through each other and giving rise to the impenetrability of solid objects. This quantum mechanical rule, combined with quantum uncertainty and electrostatic repulsion, ensures that matter remains stable and occupies space, making everyday experiences like sitting in a chair possible.
