Very well deserved!
Professor Rai Weiss of MIT (in the middle) and Professor Kip Thorne (far left) of Caltech will receive the Nobel Prize of Physics for the detection with LIGO of Gravitational Waves. They may get the prize already this year.

Valley View, Yosemite NP

Here's another shot from my Yosemite trip March 4th (Tamron 15-30mm taken at 15mm and f/8.0). The overcast was making the light challenging. The trick to getting this lens to provide sharp DOF is finding the right focus distance - usually 50' - 120'.

Half Dome, Yosemite NP

A year ago, I was writing my own black-and-white conversion program, but got busy and put this project on hold.  But this past week, Google announced it is giving away its Nik Collection which includes Silver Efex Pro.  This image is my first attempt to use Nik's SIlver Efex Pro to convert an image to BW using its red filter.  A red filter strongly darkens the sky creating high-contrast effects.  The result is pretty good, although, the very gradual change in sky hue may not look very good on some screens due to 'Mach banding' because most mobile phones' displays cannot reproduce subtle gray level gradients.  Silver Efex Pro does a lot of what I wanted to put into my program, but not everything.  Still, in light of this high-quality free program, I will probably not be completing my project. I strongly recommend downloading and evaluating this excellent, free, software.  (It may require Adobe Lightroom or Photoshop.) +Nik Collection by Google

Big news!
Today we’re making the Nik Collection available to everyone, for free.

Photo enthusiasts all over the world use the Nik Collection to get the best out of their images every day. As we continue to focus our long-term investments in building incredible photo editing tools for mobile, including Google Photos and Snapseed, we’ve decided to make the Nik Collection desktop suite available for free, so that now anyone can use it.

The Nik Collection is comprised of seven desktop plug-ins that provide a powerful range of photo editing capabilities -- from filter applications that improve color correction, to retouching and creative effects, to image sharpening that brings out all the hidden details, to the ability to make adjustments to the color and tonality of images.

Starting March 24, 2016, the latest Nik Collection will be freely available to download: Analog Efex Pro, Color Efex Pro, Silver Efex Pro, Viveza, HDR Efex Pro, Sharpener Pro and Dfine. If you purchased the Nik Collection in 2016, you will receive a full refund, which we’ll automatically issue back to you in the coming days.

We’re excited to bring the powerful photo editing tools once only used by professionals to even more people now.

Bridalveil Fall, Yosemite NP

March 3, 2016
50mm f/11 0.5 sec
From my trip 2 weeks ago.  Thanks to recent storms, all the waterfalls had a fair amount of water in them. This photo was taken from Northside Drive just east of Valley View.  The Merced River is just below this frame in the foreground.  I think I used a 0.6 ND filter for this shot, but am not positive about this.

I wish I had a DJI quadcopter! This photo demonstrates that very nice photos can be attained with this tool.

nice Aerial shot! :) I recently got a Phantom 3 Pro. Hope I can find some good spots to get photos of after I know how to pilot the thing!

Here's another shot taken at 15mm trying out my new Tamron 15-30mm lens at Pismo Beach this past December.

Famous math problem solved!

Ten days ago, Maryna Viasovska showed how to pack spheres in 8 dimensions as tightly as possible. In this arrangement the spheres occupy about 25.367% of the space. That looks like a strange number - but it's actually a wonderful number, as shown here.

People had guessed the answer to this problem for a long time. If you try to get as many equal-sized spheres to touch a sphere in 8 dimensions, there's exactly one way to do it - unlike in 3 dimensions, where there's a lot of wiggle room! And if you keep doing this, on and on, you're forced into a unique arrangement, called the E8 lattice. So this pattern is an obvious candidate for the densest sphere packing in 8 dimensions. But none of this proves it's the best!

In 2001, Henry Cohn and Noam Elkies showed that no sphere packing in 8 dimensions could be no more than 1.000001 times as dense than E8. Close... but no cigar.

Now Maryna Viasovska has used the same technique, but pushed it further.
Now we know: nothing can beat E8 in 8 dimensions!

Viasovska is an expert on the math of "modular forms", and that's what she used to crack this problem. But when she's not working on modular forms, she writes papers on physics! Serious stuff, like "Symmetry and disorder of the vitreous vortex lattice in an overdoped BaFe_{2-x}Co_x As_2 superconductor."

After coming up with her new ideas, Viaskovska teamed up with other experts including Henry Cohn and proved that another lattice, the Leech lattice, gives the densest sphere packing in 24 dimensions.

Different dimensions have very different personalities. Dimensions 8 and 24 are special. You may have heard that string theory works best in 10 and 26 dimensions - two more than 8 and 24. That's not a coincidence.

The densest sphere packings of spheres are only known in dimensions 0, 1, 2, 3, and now 8 and 24. Good candidates are known in many other low dimensions: the problem is proving things - and in particular, ruling out the huge unruly mob of non-lattice packings.

For example, in 3 dimensions there are uncountably many non-periodic packings of spheres that are just as dense as the densest lattice packing!

In fact, the sphere packing problem is harder in 3 dimensions than 8. It was only solved earlier because it was more famous, and one man - Thomas Hales - had the nearly insane persistence required to crack it.

His original proof was 250 pages long, together with 3 gigabytes of computer programs, data and results. He subsequently verified it using a computerized proof assistant, in a project that required 12 years and many people.

By contrast, Viasovska's proof is extremely elegant. It boils down to finding a function whose Fourier transform has a simple and surprising property! For details on that, try my blog article:
