Das neue Auge unseres Verstandes

CAMBRIDGE, MASS.: Die moderne Physik und Kosmologie legen nahe, dass grundlegende Wahrheiten darüber, wie die Natur funktioniert und unser Universum entstanden ist, nur für jene erkennbar sind, die Ereignisse sehen können, die kürzer dauern, als das Licht braucht, um an einem Proton vorbeizuziehen, und deren Sehvermögen Distanzen auflösen kann, die kleiner als ein Atomkern sind. Zum Glück schließt das uns Menschen nicht aus, denn wir können die Augen, mit denen wir geboren sind, verstärken.

Zum Beispiel durch den Large Hadron Collider (LHC). Indem sie in diesem mit beispielloser Energie Protonen gegeneinander schlagen und dabei die vielen Teilchen überwachen, die aus diesen Zusammenstößen hervorgehen – und die Primärereignisse rekonstruieren, die diese hervorgebracht haben –, werden die Physiker tatsächlich das schnellste, hochauflösendste Mikroskop aller Zeiten konstruiert haben, bei dem jedes Proton eine Momentaufnahme des Inneren eines anderen Protons macht.

Der LHC ist ein fantastisches technisches Projekt, über dessen zahlreiche Staunen erregende Merkmale weithin berichtet worden ist. Ich werde mir all dies ersparen und direkt zum Kern der Sache kommen: Welche Erkenntnisse können wir uns von ihm erhoffen?

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.

    DEBATE: Should the Eurozone Impose Fiscal Union?

    French President Emmanuel Macron wants European leaders to appoint a eurozone finance minister as a way to ensure the single currency's long-term viability. But would it work, and, more fundamentally, is it necessary?
