New way to calculate how long it would take to fall through a hole in the Earth
Researchers find 3-D printed parts to provide low-cost, custom alternatives for lab equipment
The 3-D printing scene, a growing favorite of do-it-yourselfers, has spread to the study of plasma physics. With a series of experiments, researchers at the Princeton Plasma Physics Laboratory (PPPL) have ...
Want to measure the distance to the Moon yourself? Now you can!
Astronomy is a discipline pursued at a distance. And yet, actually measuring that last word—distance—can be incredibly tricky, even if we set our sights as nearby as the Moon.
Osmosis: Everything you know about it is (probably) wrong
Osmosis – the flow of a solvent across a semipermeable membrane from a region of lower to higher solute concentration – is a well-developed concept in physics and biophysics. The problem is that, even though the concept ...
Everyone loves a falling slinky
(Phys.org)—If a slinky is not at the top of your Christmas list you might want to think again. Making a slinky walk down steps or draping it over your arm to imitate a robot is fun but the coiled spring ...
