Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Maldacena on Inflation

Many people have been hoping recently that observations of the cosmic microwave background might provide a “window” into high energy physics well beyond the energy scales accessible in terrestrial accelerators.

So far, however, a concrete (and detectable!) “signal” to look for has proven elusive.

Juan Maldacena has a really nice paper on the leading non-gaussian contributions to the fluctuations in a slow-roll inflationary model. He computes the 3-point functions of scalar and tensor fluctuations. The effect is order (H/Mpl)4, and so probably unobservably small.

Still, a nifty computation.
