NewYorker Cartoon-off : Katz and Munroe draw cartoons related to String Theory
Farley Katz, who draws for New Yorker magazine, ran into xkcd.com’s Randall Munroe in a grocery store. He challenged Munroe to a cartoon-off — each cartoonist to produce drawings about the Internet as envisioned by the elderly, String Theory, 1999, and one’s favorite animal eating one’s favorite food.
These are the Cartoons that each of them created for the String Theory topic:
Katz:
Munroe:
Munroe was the clear winner here! Katz drawing is not even amusing! (failed pun on “not even wrong”).
Munroe is the master of cracking “inside jokes” that only a person in the field will find funny and this is no exception.

Tuesday Physics Tattoo: Interesting Pi Tattoo designs
Pi is such an intriguing number and it pops up at places you least expect it to. No wonder it is a favorite number among the “life mystery lovers”.
Here are two Pi Tattoo designs that do justice to the inherent intrigue of the number Pi.
Here the numbers are the design!
Here the dots represent the digits, starting on top and going clockwise.
Thanks VJ for sending it.
Don’t tell me you don’t know Pi to the 20th digit! Here is a mnemonics for you.
Sun & Moon & Skies proclaim the divine author of the Universe.
or
How I wish I could enumerate Pi easily, since all these horrible mnemonics prevent recalling any of pi’s sequence more simply.
If you are looking for mnemonics in a different language, go here.

Spectacular images of Sun and its active regions at different wavelengths
Blue : 1M degrees
Green: 1.5M degrees
Red: 2M degrees
The image shows the corona for a moderately active Sun, with some (red) hot active regions in both hemispheres, surrounded by the (blue/green) cooler plasma of the quiet-Sun corona. Notice also the north polar-crown filament, the trans-equatorial loops, and the coronal hole in the south-east (lower-right) corner of the image and the smaller one over the north pole. This image shows the solar corona in a false-color, 3-layer composite: the blue, green, and red channels show the 171Å , 195Å , and 284Å wavelengths, respectively (most sensitive to emission from 1, 1.5, and 2 million degree gases). (TRACE Project, Stanford-Lockheed Institute for Space Research, NASA)
A view of a sunspot and granules on the Sun’s surface, seen in the H-alpha wavelength on August 4, 2003. H-alpha, is a specific emission line created by hydrogen at 6562.8 Angstroms.
This TRACE 171 Angstrom-wavelength image from November 11, 2006 shows a sizeable active region at the east limb of the Sun (rotated clockwise 90 degrees so north is to the right) just as it rotates onto Earth-facing hemisphere. Notice the low-lying dark structures of filaments at the leading edge of the region, some “levitating” dark material on the right-hand side of the region, and the small ephemeral region towards the lower right.
This LASCO C2 image, taken 8 January 2002, shows a widely spreading coronal mass ejection (CME) as it blasts more than a billion tons of matter out into space at millions of kilometers per hour. The C2 image was turned 90 degrees so that the blast seems to be pointing down. An EIT 304 Angstrom image from a different day was enlarged and superimposed on the C2 image so that it filled the occulting disk for effect

A rainbow : double and supernumerary
I sometimes joke that if the physicists were given all the laws of Physics and asked to create a universe, we might have come up with galaxies, and stars and suns and moons and mountains and may be even rain, but we would have never ever come up with a rainbow!
An exceptional picture of a rainbow. It was taken by Eric Rolph in Alska at Wrangell-St. Elias National Park, Alaska.

You can, of course see the double rainbow, but you also see supernumerary rainbow ; at least two of them!
On the inner fringe of the primary bow you will notice that the colors start repeating themselves for what appears to be two more cycles. Supernumerary rainbows are clearest when raindrops are small and of similar size.
