# gst: deep, super-resolution vistas through tiny tornadoes of magnetized plasma

<< To get the extremely high-resolution images vital to study new materials, microbes, and more, scientists often build microscopes based on optical vortices. >>

AA << devised a way to make optical vortices with 1000 times more power than previous methods. Their design uses strong, nonuniform magnetic fields to control plasmas, or ionized gases, to create the vortices. >>

# gst: Brownian motion from trading

<< The kinetic theory of molecules, involving many collisions between particles, leads to the emergence of physical Brownian motion. By generalizing the kinetic framework, the study showed the emergence of financial Brownian motion from decisions made by individual traders. >>

# trade: cryptocoin; No hoax. The "McAfee Redemption Unit" is real ...

<< Late last night, John McAfee, the official mouthpiece of the 'We love making outlandish statements' club dropped a pretty big bomb on the unsuspecting crypto community.
It all started when a little known cryptocurrency exchange  SmartPayMINT posted a photo of fiat currency with McAfee’s face on it. As far as we know it was an artist’s representation of what a probable currency would look like if it had McAfee’s face on it. >>

# phys: where a drum can vibrate and stand still at the same time ...

<< Mechanical vibrations, such as those that create the sound from a drum, are an important part of our everyday experience. Hitting a drum with a drumstick causes it to rapidly move up and down, producing the sound we hear. In the quantum world, a drum can vibrate and stand still at the same time >>

# acad: the matthew effect vs perpetual novelties

<< Why do scientists with similar backgrounds and abilities often end up achieving very different degrees of success? A classic explanation is that academic achievement exhibits a “Matthew effect”: Early successes increase future success chances.>>

AA << results show that winners just above the funding threshold accumulate more than twice as much funding during the subsequent eight years as nonwinners with near-identical review scores that fall just below the threshold. >>

the "Matthew effect" esteso nel qualsivoglia contesto (vale a dire: rendita di posizione stabile, carriera professionale certa, esercizio del potere di cooptazione, accesso privilegiato a risorse pubbliche e private) vs (ipotetiche entita' AI.qu.cpu autonome, costo base 10-100 usd, emivita 10y) ... come si auto giustifichera' lo status di una futura classe dirigente? Sara' sufficiente il conforto, l'appoggio sottotraccia della "famiglia",  la disponibilita' alla sottomissione/ compromesso "a prescindere", l'eventuali abilita' di chiacchera e visibilita' sui media per stabilizzarne il potere?
