The Six Degrees of Integral-Spin Particles

Bacon number

I also checked on the spinless/spineless mixup that I got at Google, and come up with these:

skinless

stainless

(Wikipedia is great, but I do dislike that the search function has placed the emphasis on article titles, rather than content. This seems to have changed somewhat, since it now gives article links, too. I don’t recall that being the case in the past.)

Harry Potter and the Alpha Particle Track

Cocktail Party Physics: chamber of secrets

By 1910, Wilson had figured out he could use his cloud chamber device to detect charged particles, since they would leave a trail of ions — and water droplets — as they passed through the gas in the chamber. He took the very first photographs of the tracks left by alpha and beta rays, not to mention evidence of how individual atoms and their electrons interacted. Both alpha and beta particles have distinctive tracks: the former is broad and straight, while the latter is thinner and more easily deflected by collisions with other particles. Apply a uniform magnetic field across the cloud chamber, and positively and negatively charged particles will curve in opposite directions. Wilson chambers became all the rage in particle physics, leading to all kinds of exciting discoveries. The discovery of the positron in 1932 at Caltech occurred thanks to a Wilson chamber, garnering physicist Carl Anderson a Nobel Prize in the process. Wilson himself snagged a Nobel, too, for his invention of the cloud chamber.

Last time I visited TRIUMF I saw the cloud chamber they had added to the lobby, and I thought it would be so easy to mount a webcam to one of these and broadcast live images. As far as I know, nobody has done this.

Conjugate This!

English Professors and other language professionals, long jealous of the attention and funding afforded the Large Hadron Collider and other “big physics” projects, have embarked on a new research initiative: that of high-energy language. The ambitious project will follow several avenues of investigation in an attempt to invigorate the field of research.

“We all know what happens when you split an infinitive,” remarked Prof. John Wurterschmidt, “but we’re only familiar with the results at pedestrian energies. Until now, nobody has investigated what happens when you do this at hundreds of MeV. Is the language relativistic? That is, we need to be finding out if words take on new meanings when they are traveling at a significant fraction of the speed of light. And, of course, the ultimate goal of discovering if there is an inherent structure to language, beyond what we give it. We really need this. A whole lot more than yet another analysis of Wuthering Heights.”

To do so, words will be accelerated to high energy and collided, and it is believed that this will result in the creation of participles and antiparticiples along with a shower of punctuation marks, mostly commas and apostrophes, but with the occasional exclamation point and question mark or even a rare ampersand, in the case of collisions involving irregular verbs. These reactions should shed some light on the asymptotic freedom behavior of individual syllables. At high enough energies, still years away from investigation, would be the creation of the Roget boson, also known as the saurus particle, which is thought to give words their meaning.

It is hypothesized that the symmetry of words is broken at some high energy of unknown value, and above this unification point words with similar meanings and etymologies are actually one word, there is no metaphor mixing and that all sentence structure is in palindrome form. That investigation will have to wait, however, as the preliminary funding will only allow for investigations of lower-energy interactions. In the initial experiments, words will be linearly accelerated to collide with a fixed target (The Oxford English Dictionary, if the collaboration can afford it), using a finely crafted “while-u-were-out” memo as a projectile. Later on, if sufficient funding is obtained, they will be able to construct a storage-ring system where nouns can be collided with their antonyms, which will be able to achieve much higher energies and allow for more exotic interactions. If all goes well, the construction of a relativistic fat novel collider will then be proposed, which will be able to explore even more aspects of the field, such as the effects of Lorentz contraction (does a novel become a short story at sufficiently high speeds?).

Wurterschmidt downplayed potential hazards of such projects, scoffing at the notion that this kind of an undertaking might prove dangerous. Some have posited that it could create a micro-meta-anthology of particularly dense and indecipherable writing which would accumulate chapters until it could devour entire libraries. “That’s poppycock. We wouldn’t be able to create anything not already being written. Stereo instructions already exist, and that hasn’t destroyed us yet.” The main danger appears to be much more mundane, as any such device must be power by a large number of monkeys typing on keyboards, which, Wurterschmidt notes, generates almost as much filth as the campus fraternities.

“Almost.”

I Do Appreciate You Being Round

The Circular Logic of the Universe

A sphere is also tough. For a given surface area, it’s stronger than virtually any other shape. If you want to make a secure container using the least amount of material, Dr. Liebovitch said, make that container round. “That’s why, when you cook a frankfurter, it always splits in the long direction,” he said, rather than along its circumference. The curved part has the tensile strength of a sphere, the long axis that of a rectangle: no contest.

Take a Trip

Examine the vast distances between planets in the solar system

This animation simulates a voyage from the sun past all nine planets. For convenience, the planets are lined up in the same direction. The animation shows each planet’s average distance from the sun.

At the speed of today’s fastest spacecraft (~20 km/second), it would take almost ten years to travel this distance. Even at the speed of light, the trip would last 5 1/2 hours. In this animation, the apparent speed of the viewer is over 300 times the speed of light.

Gammas are Busting Out All Over

NASA’s Search for New Laws of Physics

Looking at gamma-ray bursts and gamma-ray burst explosions.

These events are so mind-bogglingly intense that they can be detected from billions of light years away (and so billions of years in the past). Which is good, because you really don’t want one to get any closer than that. One popular “sudden extinction” theory is that such a burst has happened within range of our own galaxy, but because the lethal gamma radiation moves at the speed of light, the first evidence we could ‘detect’ would be everybody and everything dropping dead. The only people who could investigate it are those who evolve from particularly hardy bacteria hidden deep in a rock somewhere, evolving for billions of years then looking at fossils full of iPhones and saying “Hmm, I wonder why everybody fell over all of a sudden”.
