convention zone (13. 527)

The latest instalment of a multipart series on the Sun and its inner workings addresses in depth a fact briefly touched on in a recent post regarding the surprisingly glacial speed which a photon escapes the solar core to emerge as light and radiative energy. Whilst many of us may be cognisant of the fact that the beams of light reaching us from the Sun are eight minutes old due to the distance that they have to transverse and how looking up into the night sky is looking into the distant past, the fact that the stellar furnace is so dense that it takes a photon over one hundred thousand years to work its way through the crowd of excited particles to the surface strikes one as a strange contrast. Because protons emanate in all directions through the medium of packed plasma, the straightforward journey is impeded by obstacles at every step, the bumping into a fellow traveller and the redirection over and over again increases the time to make it from the core to the corona by a factor of a trillion, a dampening process calculated in a process called a random walk, that sustains the fusion reaction. This delayed makes the light in the sky prehistoric, older than civilisation.

half-möbius (13. 241)

Via Slashdot, we learn that IBM’s quantum computing laboratory along with a consortium of European technical universities have created a synthetic molecule C13C12 which demonstrates, a phenomenon never observed or even predicted, a unique electronic topology wherein a pulse of electrons travel through the structure in a corkscrew-like pattern. Assembled at Oxford atom by atom, the q-bit component comes in when it comes to understanding the near endlessly complex entanglement engineered of all possible states and superpositons of the particle flow, which quickly would overwhelm classical computers, increasing exponentially with each twist and turn, which can be expressed with certainty rather than projection and approximation. The chirality (see also here and here) can be switched and alter the material and chemical properties of the system.

terminal velocity (13. 018)

Though I think not taking all the factors of Newtonian physics into account, Infinite Ball Drop is a fun visualisation of the of the countdown (first spotted by Waxy) as the ball makes its descent from a special mast atop One Times Square (normally only sixty seconds and a controlled drop of one-hundred and thirty-nine feet down the pole)projected to the present time to ring in the New Year—currently some two-million feet above Manhattan with nine-hundred thousand seconds left to go. Past the thermosphere already, one can track it as it slowly plunges below the orbit of the International Space Station and the edge of space—the Kármán line (see also). The first New Year’s Eve party took place on the cusp of 1907 and 1908 and continues to this day and has inspired another similar drops and raises in places across the world through all time zones.

light-emitting diode (12. 964)

Whilst LEDs had been in use since the early 1960s as electronic components, with applications in remote control circuits, converting a pulse of current into a beam of infra-red light, and as indicator lamps for always-on appliances and in seven-segment displays, it was not until this day in 1996 when the Nichia Corporation, a Japanese chemical engineering and manufacturing concern, held a press-conference introducing brilliant white gallium nitride light-emitting diodes, after three years of experimentation and research, that the semiconductor dim bulbs, only capable of shining in invisible wavelengths to low-intensity red, hinted at their potential as a commercial lighting alternative to an infrastructure built for energy-intensive incandescents. Despite skepticism over the viability of producing a prototype using conventional technology, Nichia supported the R&D efforts of Shuji Nakamura (中村 修二, only given a token honorium for his invention, he later sued for a commensure share of the profits) whose experiments eventually netted not only the illusive white LED but also the blue laser diode in the process, the solid-state stylus for HD DVDs and Blu-Ray Discs. Incoherent and giving the illusion of pure colour saturation—like pixels and their subdivisions—LEDs produce light through electrolumininescence, the wavelength determined by the recombination of electrons and electron holes, the space of an atomic lattice where an ejected particle once was and in accordance with the shell-model could be replaced, over the gradient of the semiconductive circuit, pushing out a photon.

congrès solvay (12.838)

The preeminent series of annual alternating conferences organised by philanthropist and industrialist Ernest Solvay hosted in Brussels started in 1911 to address unsolved problems in physics, biology and chemistry, concluded its fifth and most notable session on this day in 1927, captured with this class photo (see also, referred to as the most intelligent picture ever taken) of attendees. With some tension over the participation of German scientists lifting, Albert Einstein, Max Born, Erwin Schrödinger, Werner Heisenberg and Max Plank were able to join colloquia and workshops with Niels Bohr, Auguste Piccard, Paul Dirac, Marie-Skłodowska-Curie and others to explore the topics of electrons and protons, hammering out the finer details of the newly formulated discipline of quantum mechanics. The congresses continue (on the legacy of Solvay’s fortune derived from an improved process for carbonating beverages) to this day with latest iteration on biology in scheduled for next month with talks on the subject epigenesis.

slice of time (12. 786)

Whilst having been demonstrated through several experiments—the central consequence of Albert Einstein’s special theory of relativity—as an object accelerates close to the speed of light it experiences time differently and becomes stretched through time dilation, the Doppler effect, spaghettification, etc, one conjecture, independently concluded by physicists James Terrell and Roger Penrose (see previously here and here), evaded observation: that the fast moving object out to appear not elongated nor contracted despite the physical deformation but rather rotated. Utilising a battery of tricks to simulate light speed slowed down to two-metres per second in the laboratory, we learn via Damn Interesting, recording the flashes of a laser reflected off a target wire frame cube with an advanced high-speed camera, researchers at the Technical University of Vienna have reproduced the rotation for the first time. Despite the object approaching head-one, instead of seeing one face of the cube distorted, one sees a corner formed at the convergence at the vertices of two faces. This simulation is akin to photographing a rocket whizzing by at ninety-percent the speed of light with the resulting panoramic image twisted as Penrose predicted. It is a pretty nifty set-up and a way to magnify or minimise the unachievable but seems strange to have arrived at (not discovered) this anticipated effect through brute force of better lenses rather than by reason and the scientific method.

apparent magnitude (12. 492)

Realising I had taken for granted knowing what the unit of measurement was, or what exactly it was gauging, we appreciated this introduction and overview of the decibel—via Quantum of Sollazzo. Sort of like the distinction between mass and weight, sound intensity is measured in terms of pressures in pascals as the deviation from the ambient caused by an acoustic wave through a given medium, and the decibel as a way of expressing the ratio between two values logarithmically—with the silent partner being the threshold of human hearing. Originally stemming from a technique to measure and compare signal loss over telegraph lines and later telephone circuits, first expressed as loss per miles of standard cable, the new definition developed by Bell Labs was received favourably by operators and long-distance providers, named in honour of the communications pioneer Alexander Graham Bell. Still used chiefly to calibrate signal strength and fidelity as power passes through different exchanges across a network (mathematically, it is easier to process and account for the changes in transmission media and resistance by their additive properties rather than cumulatively by logarithms, which is incidentally the reason why older hardware and appliances last longer being over-engineered by dint of material and electrical tolerances calculated with a slide-rule and rounding up adding up to machines built to a more robust standard than for their planned lifecycle. Because humans perceive an increase in loudness exponentially rather than linearly (per studies in psychophysics known the Weber-Fechner laws that demonstrate gradual increases are likely to go unnoticed by the senses, the contrasted stimuli also seen to carry an effect in registering numbers and statics, in placebos—titration of all types through interoception and voting), the dB scale became a useful measure, as with the Richter scale for earthquakes and the Fujita scale for tornados, for when a in situ judgment might fail.

fishing in the night (12. 457)

Roman Mars’ 99% Invisible cross-posting the work of a colleague and regular contributor directs us to a rather fascinating listen that synthesises a multitude of developments in radio and broadcasting that first forecasts how the medium previsions the internet and the miracle of instantaneous, round the world communication taken for granted by our modern perspective and seemingly by many contemporaries as well. The follow-on season focuses on shortwave, ceded to the pioneering amateurs with authorities considering that band to be of minimal utility and wanting safeguard AM and FM frequencies for tactical and commercial purposes with the outbreak of war. With a limited range but higher fidelity, broadcasters built antenna towers for amplitude modulation transmissions, usually reaching perhaps a county-sized audience, however after dark, listening audiences sometimes caught snatches when tuning the dial to programmes from very far afield. A phenomenon well known to the HAM radio community (see above), the signal boost was caused by the ionosphere becoming less charged by sunlight and able to refract and reflect errant signals back to ground-based receivers. Their shortwave leavings, the hobbyists discovered, had an incredible global and antipodal range which spurred the collecting of calling cards. As knowledge spread that programming and news was not restricted nocturnally, many members of the public, equipped only with standard AM receivers and spent many evenings engaged in the title practice, leaving families to bemoan these squandered evenings with their casting for transmissions in their “radio shack.” Once the potential of this belittled band was realised day or night with the potential for a station to bound around the world and picked up by anyone tuned in, however, once again the enthusiast community—as is the case with modern surfing the web—found themselves sidelined and marginalised with more licensing and crackdowns on commandeering the public airwaves when governments reclaimed the bandwidth for propagandising.

chrysopoeia (12. 443)

Although the aims of alchemists of transforming base metals into gold has been previously achieved through synthetic transmutation first in 1941 by heavy bombardment of mercury with neutrons—though the resulting isotopes were extremely radioactive and again in 1980 by Glenn Seaborg at Lawrence Livermore labs by surgically removing protons and neutrons from bismuth atoms, these demonstration projects were prohibitively expensive and would need to be scaled up a trillion-fold in order to produce a microscopic speck of the precious metal. We learn, however—via tmn—that researchers working on the ALICE programme at the Large Hadron Collider at CERN, the acronym somewhat disappointingly only standing for A Large Ion Collider Experiment designed to study conditions immediately after the Big Bang with by creating exotic plasma phases of matter, have recently detected the mass albeit very short-lived conversion of lead into gold as the extremely hot and close-packed conditions cause dissociative reactions that can cause the target element to eject a small number of protons and neutrons, producing gold (the similar densities probably what inspired the study of alchemy in the first place). The above quick-silver and thallium were also temporary by-products of nuclear transmutation. Related to the title term, χρυσοποιία, ἀργυροποιία (argyropeia) refers to artificial silver-making, usually trying with copper.

spaghettification (12. 323)

One might be familiar with the above transformation when one wanders too close to a black hole but there’s more physical properties to ponder in pasta that touch on the broader mysteries of the Cosmos. Noting the expertise required to produce the finest and most delicate varieties of angel hair, researchers applied science to create a matrix of nano-noodles to study the limits of dough and starch, inadvertently finding the resulting pasta to have enhanced stiffness and with possible applications as a biodegradable substitute for plastic. Enduring conundrums also present themselves in the form of the slurping problem—and variants—and Richard Feynman’s obsessive quandaries (previously) over why dry spaghetti always snapped in two and the physics behind stress and tension, which after a quarter of a century yielded a three way fracture with some mechanical finesse.

𝝎 = 360° sin 𝛗 / day (12. 139)

Devised by observing a lathe demonstrating an unexpected but explainable gyroscopic effect, physicist Léon Foucault first constructed his eponymous pendulum in the basement of his home on this day in 1851, bringing the experiment to the public a month later at the Meridian of the Paris Observatory. Allowing observers to conclude from the change in the plane of oscillation of a heavy weight over time the rotation of the Earth, and showing that at latitudes other than the equator the displacement of each cycle (best viewed on a very big set up) progresses relative to the turning of the Earth throughout the diurnal period. Though a long established fact that the Earth revolved, Foucault’s experiment was proof easily attainable and not necessitating watching for the minute movements of the stars and planets, rather elegantly showing that the Earth moves beneath the fixed and motionless pivot point.   Such demonstrations have become popular installations at universities and museums around the world—see one in action here from a dedicated live webcam.
