Putting Einstein to the Test
Physicists have developed an experiment involving super cold matter and an empty elevator shaft that will test one concept crucial to Einstein's Theory of General Relativity.
Physicists have developed an experiment involving super cold matter and an empty elevator shaft that will test one concept crucial to Einstein's Theory of General Relativity. The experiment may shed light onto the tension between quantum physics and Einstein's relativity. "Einstein's 'equivalence principle', which underpins general relativity, says that if you stand in a falling elevator, your acceleration should effectively cancel out the pull of gravity, leaving you unable to determine whether you are in free fall or whether there is simply no gravity present at all," says the New Scientist. "Determining whether quantum systems are also subject to this equivalence principle might help pin down why quantum theory has so far resisted any merger with general relativity – a mystery that haunts physics."
Journaling can help you materialize your ambitions.
- Organizing your thoughts can help you plan and achieve goals that might otherwise seen unobtainable.
- The Bullet Journal method, in particular, can reduce clutter in your life by helping you visualize your future.
- One way to view your journal might be less of a narrative and more of a timeline of decisions.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
