Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.

In her report, Bonnie Lysyk, the auditor general, concluded that the process for picking the land for development was largely directed by the housing minister’s chief of staff. And the report found that process was heavily influenced by two developers who, at a housing conference, handed the political aide envelopes detailing the land they wanted removed from the Greenbelt. The aide then directed a selection process that sidelined the usual reviews by nonpartisan public servants and proper public consultations.

In the end, Ms. Lysyk found, the aide picked 14 of the 15 parcels of land that were removed from the Greenbelt.

“We found that how the land sites were selected was not transparent, fair, objective, or fully informed,” Ms. Lysyk wrote, adding: “What occurred here cannot be described as a standard or defensible process.”

Land owned by those two developers, she concluded, makes up 92 percent of the Greenbelt land now open to development. That change, the audit calculated, raised the land’s value by 8.3 billion Canadian dollars.

Sparta’s military mediocrity seems inexplicable given the city-state’s popular reputation as a highly militarized society, but modern scholarship has shown that this, too, is mostly a mirage. The agoge, Sparta’s rearing system for citizen boys, frequently represented in popular culture as akin to an intense military bootcamp, in fact included no arms training or military drills

In the ‘90s, a VHS tape emerged and, with it, a claim that a UFO had crashed in a field near Ottawa. A former teen UFO investigator returns decades later to find out what people saw there

In classical optics, however, there is another way to reconstruct a 3D object. This is called digital holography, and is based on recording a single image, called interferogram, obtained by interfering the light scattered by the object with a reference light.

The team, led byEbrahim Karimi, Canada Research Chair in Structured Quantum Waves, co-director of uOttawa Nexus for Quantum Technologies (NexQT) research institute and associate professor in the Faculty of Science, extended this concept to the case of two photons.

Reconstructing a biphoton state requires superimposing it with a presumably well-known quantum state, and then analyzing the spatial distribution of the positions where two photons arrive simultaneously. Imaging the simultaneous arrival of two photons is known as a coincidence image. These photons may come from the reference source or the unknown source. Quantum mechanics states that the source of the photons cannot be identified.

Dr. Alessio D'Errico, a postdoctoral fellow at the University of Ottawa and one of the co-authors of the paper, highlighted the immense advantages of this innovative approach, "This method is exponentially faster than previous techniques, requiring only minutes or seconds instead of days. Importantly, the detection time is not influenced by the system's complexity—a solution to the long-standing scalability challenge in projective tomography."

"Imagine, just imagine, if Barack Obama in any of his 8 years in office had proudly and publicly referred to himself as ‘the apple of [Putin’s] eye,'" he wrote Friday. "The right would have had an immediate and nonstop meltdown. Fox would have demanded impeachment and indictment 24/7."

Presidential historian Michael Beschloss took a more historical approach:

"Never heard Truman boast of being the 'apple' of Stalin’s eye," he said.

fully 40% of total U.S. emissions were associated with income flows to the highest earning 10% of households. Among the highest earning 1% of households (whose income is linked to 15–17% of national emissions) investment holdings account for 38–43% of their emissions
