Tweedledum and Tweedledee Agreed to have a battle! Lewis Carroll (1871) ‘Our rock,’ we call it. Its tons of granite became solid some two billion years ago. Most recently―maybe ten thousand years ago―a glacier left it on the shoreline of a lake. On July 6 the spider shows up on our rock. She keeps to […]
Harry Potter brings cutting-edge ideas from quantum physics into the imaginations of a generation of young fiction readers. In previous posts we’ve looked at teleportation, levitation, and solids that can pass through other solids unimpeded (though not yet through brick walls). All three are examples of how quantum mechanics (QM) can make seeming-magic in the […]
The message of Dr. Bernard Forscher’s brick allegory is that data can obstruct the search for scientific explanation. Today we check a story about missing heat (recent fodder for climate-change denial). On the way to explanation we’ll see data being tweaked to say more than they should. (Data in my book is plural and datum […]
Around the world we’re starting to see same-old knee-jerk stuff. Irrational reactions to Ebola hurt us all: World Health Organization Director-General Margaret Chan says that 90 per cent of economic costs of an epidemic ‘come from irrational and disorganized efforts of the public to avoid infection.’ ‘Public’ includes public officials and push-button politicians and panicky […]
Some fifty years ago a physician at the Mayo Clinic, Bernard Forscher, wrote an allegoric letter to the editor of Science on a theme that Science Seen also explores (why science, and especially physics, is in trouble). His message―that data can block basic understanding―was pointed then. It is urgent now. Chaos in the Brickyard Once […]
Ebola is a scary virus. Most know it is deadly. It is an international problem. We need evidence-based action to solve it, not play-on-fear border closings (c.f., SARS and swine flu) that do no good but damage the economy. We need a public conversation on ebola and it might be aided by some terms you […]
Making Sense of Space Last week we looked closer at the crisis in cosmology. Physicists are inventing increasingly implausible models to describe what they observe. Clinging to descriptions, they abandon understanding. Indeed some heavy-hitter physicists propose to abandon physics. For example, American Nobel-Prize-winning physicist Steven Weinberg says: Now we may be at a new turning […]
Cosmology is in a crisis state unprecedented in the history of science. Daryl Janzen (2014) Last week’s post looked at two views of space. The tension between them has profound effects on physics that underpins many technologies that affect our lives. Historically, space is seen as either something (often called the æther or ether) or […]
Understanding physics can be satisfying. Understanding physics some physicists don’t understand brings super-satisfaction. Many think they can’t understand physics. Seems to me that often it is physicists they can’t understand. I think anybody who can figure how to travel to another country can, with no more effort, understand a lot of physics. With two provisos: […]
