Gigapan Inauguration Photo

Posted on by

Can’t remember where I first ran across this: the inauguration Gigapan photo

The artist’s blog entry, How I Made a 1,474-Megapixel Photo During President Obama’s Inaugural Address explains

I made a panoramic image showing the nearly two million people who watched President Obama’s inaugural address. To do so, I clamped a Gigapan Imager to the railing on the north media platform about six feet from my photo position. The Gigapan is a robotic camera mount that allows me to take multiple images and stitch them together, creating a massive image file.

High Pressure Yields Novel Single-element Boron ‘Compound’

Scientists have found the first case of an ionic crystal consisting of just one chemical element – boron. This is the densest and hardest known phase of this element. The new phase turned out to be a key to understanding the phase diagram of boron – the only element for which the phase diagram was unknown since its discovery 200 years ago.

But, Why?

A Dialog With Sarah …

Ask a scientist “why,” and they can often go many rounds.

SARAH: Why?

DAD: Why is soap a surfactant?

SARAH: Yes.

DAD: That is an EXCELLENT question. Soap is a surfactant because it forms water-soluble micelles that trap the otherwise insoluble dirt and oil particles.

SARAH: Why?

DAD: Why does soap form micelles?

SARAH: Yes.

DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. Can you say ‘hydrophilic’?

SARAH: Aidrofawwic

Drippy Faucets Offer Lesson In Physics

To Peter Taborek, a drippy faucet is a physics experiment. Taborek uses high-speed video to capture the motion of drops and bubbles coming apart. Knowing the details of this “pinch-off” process is important when designing inkjet printers, because ink must form a single droplet without trailing liquid. It also is useful in biotechnology when fluid is used on microchips, and it has applications in cosmetics, food and structural materials industries.

A Brief History of Stop-Motion Animation

O’Brien’s work inspired his young assistant Ray Harryhausen who followed in his footsteps by creating sequences and films that further blended stop-motion model/puppet animation with live-action footage. One of his finest pieces of work was the sequence in Jason and the Argonauts featuring a fight with seven skeletal warriors who are all performed via stop-motion animation. Not too shabby for 1963.
