Pseudophysics: The New High Priesthood

Wow.  Somewhat in balance to yesterday's reblog of part one of Coel Hellier's post defending multiverse theories as scientific, here's Amir Aczel skewering many of the proponents of multiverses and other untestable cosmological theories.  He takes aim at Brian Greene, Max Tegmark, Lawrence Krauss, and others, for presenting metaphysical assertions as science. The universe is a marvelous … Continue reading Pseudophysics: The New High Priesthood →

Non-experts challenging the expert consensus is rarely wise, even when scientists do it

Chris Mooney has an article at Mother Jones, explaining why it's not a good idea for non-scientists to challenge the scientific consensus, in the process, reviewing Harry Collins's new book, 'Are we all scientific experts now?'. Read all the online stuff you want, Collins argues—or even read the professional scientific literature from the perspective of … Continue reading Non-experts challenging the expert consensus is rarely wise, even when scientists do it →

American positions on moral issues and tensions between the moral foundations

Gallup did a poll on American positions on various moral issues, finding that Americans are now more accepting than ever on a range of issues. Most of these I don't find particularly surprising.  Of course, it turns out that Democrats and Republicans have differences of opinion on many of them.  HuffPost, in their write up of … Continue reading American positions on moral issues and tensions between the moral foundations →

The Big Bang’s Identity Crisis – The Nature of Reality

Think of the Big Bang, and you probably imagine a moment in time when matter, energy and space itself all burst into existence at once. Yet many astrophysicists now believe that the “Big Bang” was actually two distinct events: first the inaugural instant of space and time, and second the generation of most of the … Continue reading The Big Bang’s Identity Crisis – The Nature of Reality →

Max Tegmark and MinutePhysics on the mathematical universe

This is a subject that we've discussed repeatedly here, so I thought you might find Tegmark's narration of this video interesting. http://www.youtube.com/watch?v=HGG4HmlotJE I'm pretty sure that mathematics are not only something humans created, that they are based on relations we observe in the world, but beyond that, I remain largely agnostic on the Mathematical Universe Hypothesis … Continue reading Max Tegmark and MinutePhysics on the mathematical universe →

Growing doubt that gravitational waves were actually detected

Nature has an article up describing the problems with the BICEP2 results that are now being identified by various scientists.  It's actually the second one I've seen them publish on this. The astronomers who this spring announced that they had evidence of primordial gravitational waves jumped the gun because they did not take into proper … Continue reading Growing doubt that gravitational waves were actually detected →

‘Free choice’ in primates altered through brain stimulation

When electrical pulses are applied to the ventral tegmental area of their brain, macaques presented with two images change their preference from one image to the other. The study is the first to confirm a causal link between activity in the ventral tegmental area and choice behavior in primates. via 'Free choice' in primates altered … Continue reading ‘Free choice’ in primates altered through brain stimulation →

Beauty is determined by both biology and culture

Science can't determine values, and this includes aesthetics, beauty.  But that doesn't mean science has nothing to say about beauty.  As this article at PolicyMic indicates, it can study what most of us see as beauty and explore the reasons why we see it as beautiful. The primary reason we are alive is to reproduce … Continue reading Beauty is determined by both biology and culture →
