WEBPhys.org / Study finds political views, not race, shape reactions to mass shooting data. A new study from NYU Tandon School of Engineering suggests that when it comes to visualizations of mass shooting data, political ideology plays a more significant role in shaping emotional responses than racial identity. 23 minutes ago in Other Sciences.
The Moon's top layer alone has enough oxygen to sustain 8 billion ...
WEBNov 11, 2021 · Now let's assume the average depth of regolith on the Moon is about ten meters, and that we can extract all of the oxygen from this. That means the top ten meters of the Moon's surface would provide enough oxygen to support all eight billion people on Earth for somewhere around 100,000 years. This would also …
Electromagnetism is a property of spacetime itself, study finds
WEBJul 23, 2021 · In particular, our research shows how electromagnetism is an inherent property of spacetime itself. In a way, spacetime itself is therefore the aether. Electric and magnetic fields represent certain local tensions or twists in the spacetime fabric. Our research shows that the Lagrangian of electrodynamics is just the …
The secret of planets' perihelion between Newton and Einstein
WEBJun 30, 2021 · The secret of planets' perihelion between Newton and Einstein. In the early 1600s, based on astronomical observations, Kepler established that the orbit described by a planet in the solar system is an ellipse, with the sun occupying one of its foci. Assuming that a planet is subject only to the gravitational attraction of the sun, Kepler's ...
New warp drive research dashes faster than light travel dreams – …
WEBApr 16, 2021 · In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe's ultimate speed limit by bending the fabric of reality.. It was an intriguing idea—even NASA has been researching it at the Eagleworks laboratory—but Alcubierre's proposal contained problems that seemed insurmountable.
Warp drives: Physicists give chances of faster-than-light space …
WEBCompression and expansion. Physicists' current understanding of spacetime comes from Albert Einstein's theory of General Relativity. General Relativity states that space and time are fused and that nothing can travel faster than the speed of light. General relativity also describes how mass and energy warp spacetime—hefty objects like stars ...
WEBA circular pee-conomy. Doing this is quite easy: you just fill a urine dryer with an alkalising agent, connect it to your toilet, pee as usual and the urine is converted into dried fertilizer. A smart design could even make the dryer fit below the toilet so it doesn't take up a lot of bathroom space. While electricity would be needed for ...
A way to turn urine into solid fertilizer that could make farming …
WEBNov 9, 2020 · We estimate that it would cost just US$5 (£4.20) to supply an average family of four with a year's supply of alkalising agent. The output from the dryer is a solid fertilizer containing 10% nitrogen, 1% phosphorus and 4% potassium—a similar combination to blended mineral fertilizers.. The first flush toilet, invented by Alexander Cummings in 1775, revolutionized sanitation.
Dire wolves went extinct 13,000 years ago but thanks to new …
WEBJan 14, 2021 · Thanks to the hit television series Game of Thrones, the dire wolf has gained a near-mythical status. But it was a real animal that roamed the Americas for at least 250,000 years, until it became extinct towards the end of the last ice age around 13,000 years ago. While in popular culture the dire wolf is portrayed as a giant predator hunting in snow-covered, northern landscapes, most ...
