Shells can provide whispers of ocean history
Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?
Take a slow motion look at what actually happens when a water balloon bursts
In an experiment that could have implications for quantum computers and quantum simulators, researchers have used microwave pulses to control a quantum system composed of a cloud of approximately 40,000 rubidium atoms cooled nearly to absolute zero.
A very large group of people gathered to watch the muon g-2 ring on its last leg of the big move from Brookhaven National Laboratory in Long Island, NY to Fermilab in Batavia, IL.
Arthur Hebard, a University of Florida professor and experimental physicist, explains how his love for building and disassembling things influenced his interest in physics.
Muon g-2, the world's largest electromagnetic ring, is travelling in one piece from Brookhaven National Laboratory on New York's Long Island to Fermilab outside Chicago. Its arrival may lead scientists to the next big discoveries in particle physics.
Top-heavy design increases stability
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant. Researchers have uncovered fundamental principles of locomotion that robot teams could one day use to travel easily through underground tunnels.
IceCube, the world's largest observatory ever built to detect the elusive sub-atomic particles called neutrinos, has been completed in the crystal clear ice at the South Pole.
Professor Joe Incandela gives an overview of the decades-long, worldwide effort to construct and operate the LHC accelerator and the ATLAS and CMS experiments that together represent the largest, most complex systems ever built for physics research.
Fire is one of humankind's first technologies. We have been staring into the proverbial campfire for thousands of years. Yet, surprisingly there seems to be much more to learn. And now it's becoming even more important to our collective future that we know as much as we can about fire.
Physicists have succeeded in creating a vortex knot -- a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists.
By adding carbon fiber to concrete mixture, a slab of concrete is able to conduct electricity. "Smart concrete" has many potential applications, including helping structural engineers to identify trouble spots in a concrete structure long before stress or cracking is visible to the human eye.
Particle detected that could supply a missing piece of the cosmic puzzle.
Projectile motion allows hockey players to shoot the puck with a high rate of precision
NASCAR corners are divided into three parts because the car's grip changes in different parts of a turn.
Bill takes apart a cheap watch to show how it works. He describes how a tiny quartz tuning fork keeps the time.
Researchers on a scientific quest to understand 'the God particle'
In this week's episode of NSF Science Now we explore Hawaiian volcanoes, smart homes, robot locomotion and finally novel engineering ideas on the tiny wings of butterflies.
Ken Maschke tells us what it's really like to be a civil engineer
