(PhysOrg.com) -- Researchers from Australia have taken a step toward resolving a seemingly simple yet unsolved paradox known as the "two-envelope" problem. They`ve worked out a new strategy that can enable a player to beat the game in terms of increasing their payoff. The strategy could have applications in optimizing gains in investments and other areas. http://www.physorg.com/news169811689.html Other Sciences Tue, 18 Aug 2009 10:56:04 EST news169811689 (PhysOrg.com) -- For more than 50 years, many have taken the so-called Fermi Paradox to indicate that the existence of intelligent alien civilizations is an impossibility. However, a recent re-examination of the paradox points out that, rather than discounting the spread of an intelligent civilization, the Fermi Paradox merely points out that advanced civilizations with exponential growth are unlikely to exist. http://www.physorg.com/news164986606.html Space & Earth Tue, 23 Jun 2009 14:44:58 EST news164986606 Just when you thought you were beginning to understand the twin paradox (maybe), scientists have found something new to ponder. In the original version of the famous thought experiment on time dilation, one twin stays on Earth while the other twin takes a rocket at nearly light speed into space, and returns to find that he is younger than his twin on Earth. But a new version of the story now shows that the twin who experiences an acceleration can be older than the twin who doesn`t accelerate, under slightly different conditions. http://www.physorg.com/news163738003.html Physics Tue, 09 Jun 2009 04:04:48 EST news163738003 In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly. http://www.physorg.com/news155386974.html Physics Wed, 04 Mar 2009 11:03:23 EST news155386974 University of Toronto quantum physicists Jeff Lundeen and Aephraim Steinberg have shown that Hardy's paradox, a proposal that has confounded physicists for over a decade, can be confirmed and ultimately resolved, a task which had seemingly been impossible to perform. http://www.physorg.com/news151164690.html Physics Wed, 14 Jan 2009 14:11:30 EST news151164690 (PhysOrg.com) -- There was something peculiar about dolphins that stumped prolific British zoologist Sir James Gray in 1936. He had observed the sea mammals swimming at a swift rate of more than 20 miles per hour, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support those kinds of speeds. The conundrum came to be known as "Gray's Paradox." http://www.physorg.com/news146730722.html Physics Mon, 24 Nov 2008 06:32:02 EST news146730722 (PhysOrg.com) -- If space-time were constructed in such a way that you could travel back in time, it would create some pretty strange effects. One of these oddities, as many people know, is the `grandfather paradox.` Here, a person travels back in time to kill their grandfather before the person`s father is born, thus preventing their own birth. http://www.physorg.com/news146398685.html Physics Thu, 20 Nov 2008 10:18:05 EST news146398685
